    BACKGROUND
    [001] The present invention concerns wireless communications, and more particularly the detection of wireless transmissions from a user of a spectral resource.
    [002] Radio spectrum is a limited resource that must be shared among many different types of equipment such as cellular, home network, broadcast and military communications equipment. Historically, each part of the radio spectrum has been allocated for a certain use (called "licensed" and/or "primary" use). This strategy has resulted in all applications/uses not being allowed on the allocated carrier frequency except for those applications included in the license agreement. In practice, this results in large parts of the radio spectrum not being used much of the time. For example, in the ultra high frequency (UHF) band, where TV broadcasts take place, large geographic areas are not used, mainly because of the large output power required for such applications; this large output power requires a large reuse distance in order to minimize the risk of interference. An example of such geographic areas within Scandinavia is illustrated in Figure 1. In Figure 1, the shaded areas represent geographic locations in which a given carrier frequency is being used by a licensed user (eg by TV Broadcasting). In the remaining areas, the so-called "white spaces", the given carrier frequency is allocated to the licensed user, but is not actually being used by that user.
    [003] In order to make better use of licensed spectral resources, some countries in the future will allow unlicensed services (so-called "secondary" uses to take place in areas (called "white spaces") in which the licensed user (primary) is not broadcasting. However, the primary user will always have priority to use the spectrum to the exclusion of others. Therefore, some sort of detection mechanism is needed on the (unlicensed) devices to enable them to detect whether a licensed user is currently streaming. If such licensed use is taking place, the unlicensed user is required to discontinue his transmission on that carrier frequency. The most direct sensor is a signature detector adapted to detect specific signatures transmitted by the licensed/primary user (typically implemented as a matched registrar).
    [004] Another consideration regarding the detection of licensed user transmissions is the placement of the sensors. When the secondary (ie unlicensed) use is for cellular telecommunications, one solution is to include the sensors in the base station of the mobile communication system. However, because of shading fading and the like, there is a risk that the base station will not detect transmissions from the primary user despite the fact that a mobile device/terminal (generally referred to as "user equipment"- "UE") (connected to the base station) is interfering (or able to interfere) with the licensed user. One way to combat this problem is to include a detection device in all UEs operating on these white space carriers; that is, all UEs can detect licensed use of spectral resources and can respond by interrupting their own unlicensed transmissions.
    [005] A main problem with having UEs performing detection concerns the fact that detection parameters can change after the UE has been manufactured. Such detection parameters include, but are not limited to, aspects such as how sensitive the UE detection needs to be, how the licensed data traffic has been defined and what frequency ranges are of interest in the analysis.
    [006] Also another problem is that, even if the demands and/or definitions were known at the time of manufacture, it can still be very computationally intensive for the UE to perform the necessary functions for detection (ie, detection can be very demanding processing of its maximum processing capacity and/or may require excessive consumption of your battery and/or increase budget.
    [007] Therefore, there is a need for systems capable of operating in blanks in an efficient mode that seeks to reduce the cost (in terms of energy and otherwise) and complexity involved in such unlicensed operation, while still performing well. in connection with detecting potential transmissions from the primary user even in the face of changing detection requirements. SUMMARY
    [008] It should be emphasized that the terms "comprises" and "comprising", when used in this specification, are used to specify the presence of reported features, integers, steps or components; but the use of these terms does not preclude the presence or addition of one or more other features, integers, steps, components or groups thereof.
    [009] According to an aspect of the present invention, the aforementioned objectives and others are achieved in methods and apparatus that detect wireless transmissions of a user of a spectral resource. The user can be, but is not required to be, a licensed user of the spectral resource. Such operation includes operating receiving equipment within a user equipment to receive signals within a given bandwidth around a given carrier frequency. User equipment verifies that it is readily able to analyze the received signals to verify that a user signature pattern is present in the received signals. If not, it works cooperatively with a remote unit to analyze the received signals to see if a user signature pattern is present in the received signals. The analysis results are then reported to a head node.
    [0010] In some embodiments, working cooperatively with the remote unit includes verifying that the user equipment would be able to analyze the received signals to verify that the user's signature pattern is present in the received signals were it not for the lack of application software and/or information. In response to this, the user equipment requests application software and/or information from the remote unit. Application software and/or information is subsequently received from the remote unit. Then, the received application and/or information software is used by the user equipment to at least partially analyze the received signals to verify that the user's signature pattern is present in the received signals.
    [0011] In some embodiments, working cooperatively with the remote unit includes communicating a representation of the received signals (eg, raw or processed signals) to the remote unit for the purpose of obtaining at least partially analyzed results relating to whether the pattern of User signature is present in the received signals. The user equipment then subsequently receives, from the remote unit, the analyzed results at least partially relating to whether the user's signature pattern is present in the received signals.
    [0012] In some embodiments, the remote unit provides application software and/or information to the user equipment which can then at least partially analyze the signal, and the remote unit also performs part of the analysis itself, with the results of this analysis being returned to the user equipment.
    [0013] In another aspect, the operation referenced above is performed by a user equipment in a mobile communication system that is not licensed to use the spectral feature; the head node is a base station in the mobile communication equipment; and the remote unit is in direct communication with the user equipment.
    [0014] Also in another aspect, the method is performed by a user equipment on a mobile communication system that is not licensed to use the spectral feature; and the user equipment starts executing the method in response to a detection request received from a base station operating in the mobile communication system. The detection request includes, in some embodiments, a frequency and a bandwidth to be detected by the user equipment. In some embodiments, the detection request additionally includes a minimum signal level that serves as a threshold above which the user is considered to be making wireless transmissions via the spectral feature.

    [0020] The various features of the invention will now be described with reference to the figures, in which like parts are identified with like reference numerals.
    [0021] The various aspects of the invention will now be described in more detail in connection with several exemplary embodiments. To facilitate an understanding of the invention, many aspects of the invention are described in terms of sequences of actions to be performed by elements of a computer system or other hardware capable of executing programmed instructions. It will be recognized that, in each of the modalities, the various actions can be performed by specialized circuits (for example, analog and/or discrete logic gates interconnected to perform a specialized function), by one or more processors programmed with an appropriate set of instructions or by a combination of both. The term "set of circuits configured to" perform one or more described actions is used in this document to refer to any such modality (ie, one or more specialized circuits and/or one or more programmed processors). In addition, the invention it can be further considered to be fully incorporated into any form of computer-readable carrier, such as solid-state memory, magnetic disk, or optical disk containing an appropriate set of computer instructions that induce a processor to perform the techniques described in this document. Thus, the various aspects of the invention may be incorporated in many different forms, and all such forms are considered to be within the scope of the invention. For each of the various aspects of the invention, any such form of embodiments as described previously, may be referred to in this document as "logic configured to" perform a described action, or alternative. as "logic that" performs a described action.
    [0022] In an aspect of embodiments consistent with the invention, a UE (for example, at a time determined by itself or in response to a request from a head node such as a base station) performs detection in a certain frequency band . In some embodiments, the UE downloads a detection application (i.e., software) from a remote unit, which enables the UE to analyze the detected signal and determine for itself whether transmissions from a licensed user have been detected. In other embodiments, the UE receives the detected signal from the frequency band of interest and stores it (for example, in a baseband format). The stored signal sequence is then encoded and transmitted to a remote unit (e.g. the base station/head node or some other unit) which performs at least part of the detection analysis. Then, the result of the detection analysis is communicated back to the UE, which then performs any remaining necessary analysis and, based on the result, decides whether transmissions from a licensed user are present in the analyzed frequency band. A corresponding action can then be performed depending on the result.
    [0023] In yet other embodiments, the two approaches described above are combined into a single unit, with the UE making a decision as to whether it is capable of performing the analysis itself. If the answer is "yes", then it transfers the remote unit detection application and performs the analysis. If the answer is "no", then the UE sends an encoded version of the detected signal to a remote unit which, as described above, performs the analysis and returns the results to the UE. The decision as to whether the UE itself is capable of performing the analysis, for example, might be based on which licensed user it is looking for. The identity or other distinguishing marks related to the licensed user may be provided to the UE by the mobile communication network. The UE then checks, for example, when accessing a locally stored table, whether it is capable of performing-requested-detection-internally (ie, itself) or whether it needs help. The stored table contains information as to which signals the UE is capable of analyzing.
    [0024] Starting first with figures 2 and 3, figure 2 is a block diagram of an exemplary system capable of performing various aspects of the invention and figure 3 is, in one aspect, a flowchart of steps/processes/functions, performed by an exemplary UE consistent with the invention. In another aspect, Figure 3 can be considered to represent the various elements of logic 300 configured to perform the various functions described in Figure 3 and its supporting text.
    [0025] In Figure 2, a licensed user (LU) 201 is depicted operating within a geographic area that includes a blank 203. Licensed user 201 transmits a signal intended to be received, for example, by a licensed receiver 205 Although, for the sake of simplicity, only one licensed receiver 205 is shown in Figure 2, in practice there can be any number of licensed receivers, each intended to receive the signal transmitted by the licensed user 201.
    [0026] A mobile communication system is configured in accordance with various aspects of the invention to allow it to operate as an unlicensed user within blank 203. The mobile communication system includes a base station 207 that serves one or more UEs, including UE 209. In the context of the invention, base station 207 exemplifies a "head node". In other modalities a different equipment constitutes the "head node". For example, in WLAN systems, a router can operate as a head node in the context of the invention.
    [0027] The UE 209 includes circuitry configured to periodically detect whether the licensed user 201 is transmitting within the blank 203 and, in addition, to transfer, from a remote unit 211, software and/or other information necessary to analyze detected signals in the case that the UE 209 is able to perform this task were it not for the lack of software and/or other information, or alternatively to send some form of the detected radio energy in the frequency band of interest to the remote unit 211 , which then performs the analysis on behalf of the UE 209. In Figure 2, a second antenna associated with the UE 209 is depicted as a dotted line to show that the UE 209 optionally may have a dedicated communication link to communicate with the remote unit 211. In alternative embodiments, the UE 209 uses the same communication devices that are used to communicate with the base station 207. Other alternatives are also pos. possible since, in the context of the invention, a "remote unit" can be incorporated as any equipment other than the UE itself. To provide another non-limiting example, a remote unit may be a concentrator that the UE first contacts via a base transceiver station. This hub can then connect (for example, via a wired or wireless connection) to a server located on the Internet.
    [0028] In these and all other embodiments, the equipment functioning as the "remote unit" operates as described in this document.
    [0029] For the sake of simplicity, only a single remote unit 211 is shown and described in figure 2 in connection with the two different functions (i.e. transferring software/information to the UE and/or processing a signal received on behalf of of the EU 209). While such a dual function circuitry is certainly a possibility in some embodiments, in alternative embodiments there may be separate remote units, each dedicated to performing a respective task of tasks.
    [0030] Referring now to figure 3, functions and the set of circuits by which they are performed are shown. The UE 209 is connected to the base station 207 (head node) and is requested by the base station 207 to perform detection on a certain carrier frequency for a signal having a certain bandwidth (BW) (or carrier frequencies and bandwidths in the case of non-contiguous frequency bands are detected) (step 301). The detection request may expressly identify the carrier frequency and bandwidth to be detected, or alternatively the UE 209 may be pre-programmed to already have this information available from a local source. The detection request may additionally include a minimum signal level that the UE 209 (or circuitry 300 included in a UE consistent with embodiments of the invention) will use as a threshold above which a detected signal is considered to be a transmission of the licensed user; below this threshold UE operation is not considered to interfere with a licensed user. The detection that the UE is requested to perform may be on the same carrier frequency and bandwidth as a signal it receives from or transmits to base station 207, but this is not a requirement. The detection request may, but not necessarily, include a measurement sampling interval to be used when detecting. Yet another information that the detection request may include, but not necessarily, is some kind of indicator of which signal signature to search for, or a reference to a communication standard that defines for the UE which signal signature to search for. In summary, the various pieces of information that will influence the detection operation of the UE 209 can be obtained by the UE 209 in any of several ways, such as by querying a database, which can be pre-stored locally within the UE 209 or can be stored within the UE 209 after a head node update. An update like this can be broadcast to all nearby UEs, or alternatively it can be directed to UE 209 via dedicated signaling.
    The UE 209 receives the detection request (step 303) and, in response to this, the UE 209 receives signals in the frequency range/ranges of interest (i.e. as specified by the detection request) using an antenna and a radio receiver (step 305). The signal energy received in this operation can be stored for further analysis and/or processing.
    [0032] The antenna and radio receiver used for detection can be an integral part of UE 209. However, this is not a requirement. For example, in some embodiments, the UE 209 can only be expected to perform detection when it is located in a "hot spot" where antenna and receiving components can be shared through, for example, network communication equipment. Bluetooth® personal area or something similar. For a Frequency Division Duplexing (FDD) system, there is really no need for a UE that is capable of receiving on frequencies it uses only for transmission, so a shared external device like this can be a valuable resource.
    [0033] In an aspect of embodiments consistent with the invention, the UE checks whether it is readily able to analyze the detected signal (decision block 307). As used in this document, the term "readily capable" means "capable of performing the indicated function without any additional hardware modification or provision of new or additional software or other information". The answer can be "no" for any of a number of reasons. For example, the UE may not have the latest version of a detection/analysis application needed to perform the task. Or information needed to perform the detected signal analysis (for example, the signature of a signal being transmitted by the licensed user 201) may have changed after the UE was manufactured or after the last time you performed the analysis. Yet another possibility is that there may not be enough processing power in the UE to perform the necessary analysis of the received signal. The enumeration of these few possibilities is intended to serve merely as an example, and is not intended to limit the scope of the invention.
    [0034] If the UE is readily able to analyze the detected signal ("SIM" path outside decision block 307), then it performs the analysis of the detected signal (step 309). The analysis results are then tested to verify that a licensed user's signature was detected (decision block 311). If so ("YES" path outside decision block 311), then an indication is sent back to the head node, informing that a signal signature ("SS") has been detected (step 313). The head node receives the indication and proceeds in this way (step 315).
    [0035] In alternative embodiments, the UE, upon verifying that the signal signature has been detected, can itself decide whether to use the detected frequency band, and the head node is merely informed of the decision.
    [0036] Returning to the discussion of decision block 307, if the UE is not readily able to analyze the detected signal ("NO" path outside decision block 307) then it is checked whether the provision of application software and/or or other information would be sufficient to make the UE readily able to analyze the detected signal (decision block 317). If the answer is "yes" ("YES" path outside decision block 317), then the UE sends a request to a remote unit for it to transfer the required application software and/or other information (step 319). The remote unit receives the request, and transfers the requested application software and/or other information to the UE (step 321).
    [0037] The UE, upon receiving the requested application software and/or other information from the remote unit, then proceeds to analyze (at least in part) the detected signal (step 309) and perform further processing as described above.
    [0038] Returning to the discussion of decision block 317, if the UE cannot be made able to perform the required analysis of the detected signal ("NO" path outside decision block 317), then it sends the stored signal (" raw" or processed in some way) to a remote unit in order to offload this job or at least part of it (step 323). Any type of known transmission method can be used for this communication.
    [0039] The remote unit receives the signal, performs the requested analysis for it and then sends the results back to the UE (step 325). The UE receives the analysis results from the remote unit (step 327) and then proceeds directly to determine whether a signal signature has been detected in the detected signal (decision block 311). Further processing proceeds as described above.
    [0040] To further illustrate concepts present in embodiments that are consistent with the invention, another figure will be discussed. Figure 4 is, in one aspect, a flowchart of steps/processes/functions performed by an exemplary UE consistent with the invention. In another aspect, Figure 4 can be considered to represent the various elements of logic 400 configured to perform the various functions described in Figure 4 and its supporting text.
    [0041] The illustrated mode starts with the UE receiving a detection request (step 401) from a head node and, in response to this, the UE receiving signals in the frequency range/ranges of interest (i.e. as specified by detection request) using an antenna and a radio receiver (step 403). The signal energy received in this operation can be stored for further analysis and/or processing.
    [0042] The UE then checks whether it is readily able to fully analyze the received signals itself to check whether a licensed user signature pattern is present in the received signals (decision block 405). If so ("SIM" path outside decision block 405), the UE circuitry performs the analysis itself (step 407).
    [0043] However, if for some reason the UE is not readily able to fully analyze the received signals itself to verify that the licensed user's signature pattern is present in the received signals ("NO" path outside decision block 405) , the UE responds by working cooperatively with a remote unit to analyze the received signals to check whether a licensed user signature pattern is present in the received signals (step 409). In some embodiments, this may mean working with the remote unit to obtain software and/or other information necessary to make the UE readily capable of performing the desired analysis. In other embodiments, this may mean sending a representation of the received signal ("raw" or processed in some way) to the remote unit, which performs the desired analysis and returns the results.
    [0044] Also in other modalities, both aspects can be used. That is, a remote unit can be consulted to provide application software and/or information that enables the UE to at least partially analyze the signal, and then the same or a different remote unit is consulted to perform the rest of the analysis, which results are returned to the UE.
    [0045] In still other modalities, the UE, at the beginning, is able to partially analyze the signal, and so it does this. The partial results of the analysis are then communicated to a remote unit which completes the analysis and returns the results to the UE.
    [0046] Also in other embodiments, a remote unit is used to partially analyze the signal, and the partial results are returned to the UE which then completes the analysis.
    [0047] Those of ordinary skill in the art will recognize from the foregoing description that there are many cooperation combinations that are possible between the UE and the remote unit, and all of these are intended to be within the scope of the invention.
    [0048] Figure 5 is a block diagram of a UE 501 adapted with circuitry configured to carry out the various aspects of the invention. For purposes of clarity, only those components having particular relevance to the invention are shown. Persons of ordinary skill in the art will readily understand that the UE 501 also includes another circuitry (not shown) that is well known in the art and therefore need not be described in this document.
    [0049] In this example, the UE 501 employs so-called multiple-input, multiple-output (MIMO) communication technology. MIMO systems employ multiple antennas at the transmitter and receiver (for example, the UE antennas 503-1, 503-2, ..., 503-N) to transmit and receive information. The receiver can exploit the spatial dimensions of the signal at the receiver to achieve greater spectral efficiency and higher data rates without increasing bandwidth. However, the use of MIMO communication technology is not an essential resource for the invention; in alternative embodiments, the UE 501 can employ exactly a single antenna.
    [0050] The base station (head node) (not shown) communicates with the UE 501 via a multipath channel. In downlink transmissions, an information signal, 1(t), (e.g. in the form of a binary data stream) is provided to the base station, which applies processes such as error encoding, bit mapping input for complex modulation symbols and generate transmit signals for each of one or more transmit antennas. After upconversion, filtering and amplification, the base station transmits the transmit signals via its one or more transmit antennas to the UE 501.
    [0051] Receiving equipment in the UE 401 demodulates and decodes the signal received in each of its antennas 503-1, 503-2,..., 503-N. UE 501 includes a controller 507 for controlling operation of various UE components, including receiver signal processing circuitry 505. Receiver signal processing circuitry 505 demodulates and decodes the signal transmitted by the base station. In the absence of bit errors, the output signal from UE 501, 1(t), will be equal to the original information signal 1(t).
    [0052] The controller 507 is further configured to make the UE 501 perform processes such as those exemplified by the UE-related steps shown in one and the other of Figures 3 and 4. As mentioned earlier, the UE 501 may include (but not in all modes) the short range transceiver equipment (TRX) 509 to enable it to communicate with one or more remote units. The TRX short-range equipment 509 can operate in accordance with any of several known short-range communication technologies, such as BluetoothT0 communication equipment, WLAN equipment and so on.
    [0053] Various embodiments of the invention are capable of improving unlicensed operation of communication equipment in an area allocated for use by a licensed user, in which the UE detects operations (that is, to determine whether the licensed user is currently using licensed spectral resources) are simplified. This may include any combination of: • transferring the detection algorithms and/or other information from a remote unit, where the detection algorithms and/or other information makes the UE capable of analyzing a detected signal to detect the presence of a signature of sign associated with a licensed user; • let a remote unit perform at least parts of the analysis required to detect the presence of a signal signature with a detected signal.
    [0054] The UE detection requirements in white space applications are thus made easier and more flexible, which in turn results in lower cost and other benefits relating to white space detection in the UE.
    [0055] The invention has been described with reference to particular embodiments. However, it will be readily apparent to those skilled in the art that it is possible to incorporate the invention in specific forms other than those of the embodiment described above. The modalities described are for illustrative purposes only and should not be considered restrictive in any way. The scope of the invention is provided by the appended claims, rather than the foregoing description, and all variations and equivalences which fall within the range of claims are considered to be covered therein.
