    FIELD OF INVENTION
    Exemplary and non-limiting embodiments of the present invention generally relate to wireless communication systems, methods, devices and computer programs, and more specifically relate to downlink and data transmission reference signal to user equipment , such as Rel-10 user equipment (LTE-Advanced). BACKGROUND OF THE INVENTION
    This section is intended to provide a background or context for the invention that is described in the claims. The present description may include concepts that can be implemented, but are not necessarily those that were previously conceived, implemented or described. Therefore, unless otherwise indicated herein, what is described in this section is not prior art to the description and claims of this application and is not admitted to be prior art by inclusion in this section.
    The following abbreviations that can be found in the specification and/or the drawing data are defined as follows:

    A modern communication system is known as an evolved UTRAN (E-UTRAN, also referred to as UTRAN-LTE or as E-UTRA). In this system, the DL access technique is OFDMA, and the UL access technique is SC-FDMA.
    A specification of interest is 3GPP TS 36,300, V8.11.0 (2009-12), Third Generation Partnership Project; Specification Group Radio Access Network; Evolved Universal Terrestrial Radio Access (E-UTRA) and Evolved Universal Terrestrial Radio Access Network (EUTRAN); General description; Phase 2 (version 8), incorporated herein by reference in its entirety. This system may be referred to for convenience as LTE Rel-8. In general, the set of specifications generally denoted as 3GPP TS 36.xyz (eg 36,211, 36.311, 36,312, etc) can be seen as describing the LTE Version 8 system. More recently, release 9 versions of at least some of these specifications have been published, including 3GPPTS 36,300, V9.3.0 (2010-03).
    Figure 1A reproduces Figure 4.1 of the 3GPP TS 36.300 V8.11.0, and shows the general architecture of the EUTRAN system (Rel-8). Reference can also be made to Figure 1B. The E-UTRAN system includes eNBs, providing the E-UTRAN user plane (PDCP / RLC / MAC / PHY) and control plane protocol (RRC) terminations for the UEs. The eNBs are linked together via an X2 interface. The eNBs are also linked via an S1 interface to an EPC, more specifically to an MME via an MME S1 interface and an S-GW via an S1 interface (MME / S-GW 4). The S1 interface supports a many-to-many relationship between MMES / S-GWS / UPES and eNBs.
    The eNB has the following functions: functions for RRM: RRC, Radio Admission Control, Link Mobility Control, dynamic resource allocation for UEs, both in UL and DL (scheduling); IP header compression and user data stream encryption; selection of an MME in an EU annex; routing of User Plans in relation to EPC (MME / S-GW); programming and transmission of paging messages (originated from the MME); scheduling and transmission of broadcast information (sourced from MME or O&M); and a measurement and configuration of mobility measurement and scheduling reports.
    Of particular interest here are additional versions of 3GPP LTE (eg LTE Rel-10) aimed at future IMTA systems, referred to herein for convenience only as LTE-Advanced (LTE-A). Reference in this regard can be made to 3GPP TR36.913, V9.0.0 (2009-12), Third Generation Partnership Project; Technical Specification Group Radio Access Network; Requirements for other enhancements to E-UTRA (LTE-Advanced) (Version 9). Reference can also be made to 3GPP TR 36.912 V9.3.0 (2010-06) Third Generation Partnership Project Technical Report; Technical Specification Group Radio Access Network, the feasibility study for further advances to E-UTRA (LTE-Advanced) (Version 9).
    The goal of LTE-A is to deliver significantly increased services through higher data rates and lower latency at a reduced cost. LTE-A is aimed at extending and optimizing LTE 3GPP Rel-8 radio access technologies to provide higher data rates at a lower cost. LTE-A will be an optimized radio system meeting the ITU-R requirements for IMT-Advanced while maintaining compatibility with LTE Rel-8.
    As specified in 3GPP TR 36.913, LTE-A must operate on spectrum allocations of different sizes, including wider spectrum allocations than LTE Rel-8 (eg up to 100MHz) to achieve the peak data rate 100 Mbit/s for high mobility and 1 Gbit/s for low mobility. It was agreed that carrier aggregation should be considered for LTE-A in order to support bandwidths greater than 20 MHz. Carrier aggregation (CA), where two or more support elements (CC) are aggregated , is considered for LTE-A in order to support transmission bandwidths greater than 20MHz. Carrier aggregation can be contiguous or non-contiguous. This technique as a bandwidth extension can provide significant benefits in terms of peak data rate and cell throughput compared to non-aggregate operation as in LTE Rel-8.
    A terminal can simultaneously receive one or several transport elements, depending on its capabilities. An LTE-A terminal with reception capability beyond 20 MHz can simultaneously receive transmissions on multiple component carriers. A Rel-8 LTE terminal can receive transmissions on a single-component carrier only, as long as the component carrier structure follows Rel-8 specifications. Furthermore, it is required that LTE-A must be compatible with LTE Rel-8 in the sense that a Rel-8 LTE terminal must be operable in the LTE-A system, and that an LTE-A terminal must be operable in a system Rel-8 LTE.
    In the context of LTE-A MIMO DL improvements it was decided to introduce two types of downlink reference signals. The first is referred to as DM-RS. DM-RS is a UE-specific precoded reference signal used for data detection/demodulation for up to eight spatial layers. The second DL reference signal is referred to as CSI-RS. CSI-RS is a cell-specific reference signal used for CQI / PMI / RI and sound channel determination. CSI-RS has a lower time/frequency density compared to, for example, CRS which is specified for use in Rel-8.

In this document, the impact of CSI-RS insertion in LTE Rel-8 PDSCH is discussed. It is reported that replacing Rel-8 RE PDSCH for LTE-A CSI-RS transmission may degrade Rel-8 PDSCH performance because legacy UE would treat corresponding REs as data and include them in channel decoding PDSCH. This situation is considered to be worse than decoding usually with an erasure. Based on the simulation results, it was concluded that when the CSI-RS transmission interval is shorter than 5 ms, the performance impact for the PDSCH Rel-8 is obvious, in the case of a high modulation order speed or encoding. To maintain good performance for a range of 2ms or 5ms, the CSI-RS should have low frequency density, eg less than 6 RE. Other solutions include tuning MCS to a Rel-8 PDSCH packet when an RB has a CSI-RS inserted. It was also noted that a uniform distribution of CSI-RS causes less performance loss of Rel-8 PDSCH than a continuous distribution.
    It was agreed in 3GPP RAN1 that the CSI-RS density is one RE per antenna port per PRB per subframe. Two examples of CSI-RS subframe patterns are shown in Figure 1C. CSI-RS is not necessarily present in every DL subframe, and can be configured with a duty cycle of, for example, 2, 5 or 10 ms.

    During RAN1 #60bis it was decided that the match rate should be applied to the CSI-RS locations for the Rel-10 UE, and that the server cell's PDSCH RE mapping avoids the serving cell's CSI-RS.

    Related to the background discussion above, it can be seen that for Rel-8/9 UEs (terminals), which are not aware of the existence of CSI-RS, the RE PDSCH mapping cannot avoid the CSI-RS cell locations server. Therefore, in a case where there is PDSCH transmission to a Rel-8/9 terminal in a subframe containing the CSI-RS REs it will puncture (replace) the Rel-8/9 PDSCH REs without any terminal sensitization Rel-8/9 of the additional PDSCH interference source experienced by the UE decoder.
    The eNB may take actions to mitigate such interference. For example, the eNB can avoid scheduling Rel-8/9 UEs in subframes containing CSI-RS, or can adjust (step down) the MCS level for affected UEs in order to overcome interference by the CSI-RS. That is, the eNB can make the UE Rel-8/9 operate with a more robust MCS, in order to alleviate to some degree the additional interference experienced by the UE due to the presence of the CSI-RS.
    Furthermore, regarding the exemplary embodiments of the present invention it can be noted that in the Rel-8/9 version of the LTE specification there is no explicit signaling mechanism that informs the UE at which exact time the network is correctly acquired its radio capabilities and met version information (eg Rel-8 or Rel-9) of the EU.
    Figure 3 shows the EU capacity transfer procedure described in section 5.6.3 of 3GPP TS 36.331 V9.3.0 (2010-06) Technical Specification Third Generation Partnership Project; Technical Specification Group Radio Access Network; Evolved Universal Radio Terrestrial Access (E-UTRA), Radio Resource Control (RRC); Specification protocol (version 9). Figure 5 shows the UE RRC connection reconfiguration procedure described in section 5.3.5 of 3GPP TS 36.331 V9.3.0.
    As shown in Figure 3, UE capability transfer is not recognized in upper layer (and due to L1 errors it can fail without knowledge that UE failure occurred). If an event like this error occurs, a Rel-10 UE entering a cell with CSI-RS transmission enabled, could experience CSI-RS interference just like a Rel-8/9 UE. Furthermore, the UE can perform the rate-matching of the entire CSI-RS, while the eNB, unaware of the Rel-10 capability of the UE due to the lack of signaling transfer capability, would continue the corresponding PDSCH rate as if the UE Rel-8/-9 was capable. This could result in a transmission failure.
    For example, the eNB can request the capabilities of the UE and, after a successful UE capability transfer procedure, uses the RRC connection reset procedure (figure 5) to configure the UE for a specific transmission mode (TM) 8de Rel-9 (or specific Rel-10) (or TMx, where x>8, which is predicted to be part of Rel-10 specifications). This series of events would be an implicit indication to the UE that the network has correctly acquired its UE radio capabilities, and that the network is aware of the UE release. On the other hand, if the UE transfer capability fails (figure 3), it is possible that the transfer capability cannot be followed by the RRC connection reconfiguration procedure (Figure 5) to configure the UE to, for example, TM 0 or 1. These exemplary TMs are independent release and can be operated (with some restrictions) without network knowledge of actual UE radio capabilities/release. After such a series of events have occurred, the EU cannot be assured that the network has truly and precisely acquired the EU radio capabilities. That is, receipt by the UE of the RRC connection reconfiguration procedure that configures the UE at, for example, TM 0 or 1 does not guarantee to the UE that the network has actually acquired the UE configuration parameters previously.
    As a background to the above discussion, the information bits to be transmitted over the PDSCH are turbo encoded and then combined with the circular buffer rate. That is, depending on the number of available ERs (symbols) the correct number of coded bits is taken from the circular buffer (DC) for transmission (for code rate of 1/3 it is entire CB, for code rate > 1/3 a subset of the CB bits is transmitted, for a code rate < 1/3 CB bits are repeated wrapping around the circular buffer). Thus, the "matching rate around RS CSI" generally means that both the UE and the eNB know that certain REs (symbols) are not available for the PDSCH and this is taken into account in the matching rate process. A puncture of PDSCH by CSI-RS means that in the process the rate of matching CSI-RS REs (symbols) is assumed to be available for the PDSCH, but in the next step the PDSCH symbols in the CSI-RS REs are replaced by the CSI symbols -LOL. In case both punctures and rate corresponding the same number of PDSCH REs is transmitted, but rate matching has better performance, especially for high code rates.
    Reference in this regard can be made with Figure 4 (discussed in more detail below), where the circular damper does not demonstrate simplicity and generality. That is, Fig. 4 is an example of rate-matching and an exemplary CSI-RS puncture pattern, where the left side assumes PDSCH transmission based on DM-RS- while the right side assumes PDSCH transmission based on CRS.
    The aforementioned agreement on the correspondence rate around CSI-RS is justified from a performance standpoint. However, considering the previous scenarios it creates at least the following problem.
    The eNB shall use the PDSCH match rate around CSI-RS when it is known that a particular PDSCH transmission is targeted by a Rel-10 UE. However, and as highlighted above, the moment at which the UE knows that the eNB has correctly acquired its UE radio capabilities (and therefore is aware of the UE release) is not well defined. The eNB can perform a reconfiguration of the CSI-RS (eg change the number of antenna ports in real time, motivated by energy savings, for example). However, increasing the number of RS-CSI ports in real time can lead to additional PDSCH puncture and increased interference in the UE, and consequently a loss in performance.
    Alternatively, reducing the number of RS-CSI ports can create silenced REs, assuming that PDSCH remains with the match rate around the set of CSI-RS REs, before switching, which in turn reduces the overall spectrum efficiency. In the case where the eNB activates / deactivates ER silencing or modifies the ER silencing parameters (eg by an increase or a decrease in the reuse factor) for the inter-CSI cell measurements, then the corresponding rate of the PDSCH around the silenced set of ERs must occur to avoid performance degradation, similar to the case of a real-time change in the number of CSI-RS ports.
    From the standpoint of exemplary embodiments of the present invention, silenced REs can be considered to have the same effect as CSI-RS REs. That is, they (and possibly in some subframes along with CSI-RS) either cause PDSCH puncture or the PDSCH rate is combined around silenced REs. In general, a muted RE is an RE with zero power from a given cell, and the presence of muted REs can improve the intercellular measurements of a UE in CSI-RS for the purpose of DL transmission systems , with the participation of several cells.
    In the case where there is no common understanding between the UE and the eNB as to which the rate-matching is used for the PDSCH transmission then it follows that the PDSCH transmission cannot be correctly decoded by the UE.
    Exemplary embodiments of the present invention address and resolve these various problems and difficulties. It should be noted that the problem related to the correspondence rate discussed above is applicable to all transmission modes (not just the specific 10 Rel-TMs).
    Before describing in detail the exemplary embodiments of the present invention, reference is made to Figure 2 to illustrate a simplified block diagram of various electronic devices and apparatus that are suitable for use in practicing the exemplary embodiments of the present invention. In Figure 2, a wireless network 1 is adapted for communication via a wireless connection 11 with an apparatus, such as a mobile communication device, which may be referred to as a UE 10, via a network access node , such as one from node B (base station), and more specifically an eNB 12. Network 1 may include a network control element (NCE) 14, which may include the MME/SGW functionality shown in Figure 1A, and it provides connectivity to an additional network such as a telephone network and/or a data communications network (eg internet). The UE 10 includes a controller, such as at least a computer or data processor (DP) 10A, at least one non-transient computer readable memory means built-in such as a memory 10B (MEM) that stores a program of instructions. of computer (PROG ) COI, and at least one suitable radio frequency (RF) transceiver 10D for bidirectional wireless communications with the eNB 12 via one or more antennas. The eNB 12 also includes a controller, such as at least a computer or a data processor (DP) 12A, at least one computer readable memory means incorporated such as a memory 12B (MEM) which stores a program of computer instructions ( PROG) 12C, and RF transceivers 12D suitable for communicating with UEs 10 via a plurality of antennas and antenna ports when multiple input/multiple output (MIMO) operation is in use. The eNB 12 is coupled via a data/control path 13 to the NCE 14. Path 13 can be implemented as the S1 interface shown in Figure 1A. The eNB 12 can also be coupled to another eNB via the data/control path 15, which can be implemented as an X2 interface shown in Figure 1A.
    For the purposes of describing exemplary embodiments of the present invention, the UE 10 can be assumed to also include RRC / PHY (LI) 10E functions, the eNB and 12 can be assumed to include a corresponding RRC / PHY (L1) 12E functions . The eNB 12 AND RRC / PHY (L1) functions can be assumed to function to provide PDSCH CSI-RS puncture, rate matching and related operations as well as perform RRC signaling to and from the UE 10, and are improved for operation with the exemplary embodiments of the present invention, as described in detail below. The functions UE 10 RRC / PHY (L1) 10E can be assumed to operate to receive and interpret the CSI-RS puncture of the PDSCH, to perform rate matching and related operations, as well as perform the RRC signaling and the eNB 12, and are improved to function with the exemplary embodiments of the present invention, as described in detail below.
    At least one of PROGS 10C and 12C is assumed to include program instructions which, when executed by the associated DP, allow the device to function in accordance with exemplary embodiments of the present invention, as will be discussed in greater detail below. That is, the exemplary embodiments of the present invention may be implemented, at least in part, by computer software executable by the DP 10A of the UE 10 and/or by the DP 12A of the eNB 12, or through hardware, or by a combination of software and hardware (and firmware).
    In general, the various UE 10 embodiments may include, but are not limited to, cellular phones, personal digital assistants (PDAs) with wireless capability, wireless communication capable laptops, capture devices. of images, such as digital cameras having wireless communication capabilities, gaming devices with wireless communication capabilities, music storage and playback devices with wireless communication capabilities, Internet devices enabling wireless Internet access and navigation, as well as handheld units or terminals that incorporate combinations of such functions.
    Computer readable MEMs 10B and 12B can be of any type suitable for the local environment and a technique can be implemented using any suitable data storage technology, such as memory-based semiconductor devices, random access memory, read-only memory , read-only programmable memory, flash memory, magnetic memory devices and systems, memory devices and optical systems, fixed memory is removable memory. PD 10A and 12A can be of any type suitable for the local technical environment, which may include one or more of the general purpose computers, special purpose computers, microprocessors, digital signal processors (DSP) and architecture-based processors multi-core, as non-limiting examples.
    In accordance with exemplary embodiments of the present invention, before the UE 10 becomes aware that the eNB 12 has correctly acquired the radio capabilities of the UE 10 (and therefore the release (e.g., Re1-8, Re1-10 ) from the UE), the PDSCH transmission to the UE 10 is punctured by CSI-RS REs and both the eNB 12 and the UE 10 (i.e., the eNB 12 and UE 10 RRC / PHY (L1) functions 10E, 12E) use this hypothesis in transmission / rate matching and reception / rate matching, respectively), whenever PDSCH and CSI-RS are to be transmitted in the same subframe.
    After the UE 10 has learned that the eNB 12 has correctly acquired the radio capabilities of the UE, the PDSCH transmission to the UE is the same rate of about CSI-RS RES.
    The time when the rate-matching mode is changed as defined above by explicit downlink signaling, or by implicit signaling/rule.
    Describing the exemplary modalities in more detail, the application of methods and apparatus is considered to have at least two aspects.
    The rate of correspondence around CSI-RS and PDSCH and the PDSCH CSI-RS punch is shown in Figure 4. These two modes can be defined by specifying which set of REs is available for PDSCH transmission (in 3GPP TS 36.211) . Furthermore, if some REs are silenced (not shown in Figure 4), to facilitate measurements or inter-cell interference, these silenced REs are treated in the same way as CSI-RS REs, ie, the PDSCH match rate it is also performed around the silenced RES or the puncture of PDSCH and silenced RES.
    Figure 4 illustrates an example match and puncture rate for an exemplary CSI-RS pattern. In Figure 4 PDCCH, CRS, UE-specific, RS and CSI-RS are not shown for simplification (compare with Figure 1C). In Figure 4, the left side (Figure 4A) assumes PDSCH transmission based on DM-RS while the right side (Figure 4B) assumes PDSCH transmission based on CRS.
    In the second aspect, defining the point at which the mode match rate will be changed can be achieved, for example, by explicit signaling implemented as RRC signaling (L3). In this case, this can be a new additional DL acknowledgment message added in the UE 10 capacity transfer procedure (Figure 3), or a new parameter can be added in the RRC connection reset message (Figure 5) that defines the CSI- RS and/or rate match mode related to RE muted. Explicit signaling can also be performed by DCI signaling (L1/L2), such as by using a bit (or by common encoding with some other DCI field) in Rel-10 DL pockets indicating the rate-matching mode.
    In the second aspect, the definition of the point at which the correspondence rate mode is changed can be obtained through the use of an implicit rule (possibly in combination with the signaling). An implicit rule of thumb might look like the following.
    Rule: A Rel-10 network supporting CSI-RS, potentially including the possibility of RE muting, uses the RRC connection reconfiguration process (Figure 5) only after the Rel-10 network has correctly acquired the UE 10 radio capabilities The use of the RRC connection reconfiguration procedure is thus interpreted by UE 10 as an implicit indication so that the CSI-RS related correspondence rate is changed. More specifically, due to the asynchronous nature and/or possible errors, the eNB 12 starts to match the rate around CSI-RS, for a given UE 10 only after it has received the complete RRC connection reset message from that UE 10.
    An alternative modality is that the UE 10 applies the match rate mode change in accordance with the delay rules of RRC procedures with some residual configuration ambiguity, or the synchronous RRC reconfiguration is used via intra-cell transfer to avoid the ambiguity of the residual configuration.
    More specifically, in RRC Rel-8 and Rel-9 connection reconfiguration, and due to the RRC procedure delay, there may be some ambiguity between the eNB and UE (eg a few ms) about when the new configuration is applied in the UE 10. This ambiguity is accepted or, if not acceptable, an intra-delivery cell is used as a way to ensure a synchronous reconfiguration in the UE (no time ambiguity). Reference may be made, for example, to section 11.2, "Delay requirements processing for RRC procedures", of the above 3GPP TS 36.331, as well as section 5.3.5.4, "Receiving an RRC Connection Reconfiguration including the information of mobility control by the EU (delivery) "of the 3GPP TS 36,331. Additional general information regarding intra-delivery cell (in a different context) can be found in 3GPP RAN TSG GT1 Meeting #60bis, RL-102291, Beijing, China, April 12 - 16, 2010, Source: NTT DoCoMo, Title : Assignment of UE Methods during CIF configuration, specifically in the section titled "Method 2: Employ time synchronization using RACH (eg intra-delivery of eNodeB)".
    Before the eNB 12 applies the match-shifted rate mode to a UE 10 Rel-10, if the UE knows the CSI-RS (and potentially muted RE if specified / enabled) setting, the UE 10 can mitigate some of the interference of punches (eg for paging, RACH response, and transmission of system information). Therefore, even according to the exemplary modalities of the CSI-RS (and silenced RE) the configuration is transmitted by an Information System in the SIB (or in the MIB). The inclusion of this information in a SIB (MIB) is desirable, at least from the point of view of varying the number of RS-CSI antenna ports and/or real-time muting parameters. In this case, similarities are achieved with the specification and execution aspects considered in real-time CRS antenna port number change. However, exemplary modalities are not precluded in the case where the CSI-RS (and RE muted) configuration is provided via dedicated RRC signaling.
    Based on the above, and for the purpose of describing exemplary embodiments of the present invention, the first rate-match mode may comprise puncturing the downlink shared channel transmission with a set of resource elements, and the second rate mode may comprise the corresponding downlink rate of the shared channel around those resource elements which are members of the resource element set. The set of resource elements can include, for example, one or more REs containing CSI-RS symbols, as well as possibly one or more muted REs.
    There are a number of technical effects, advantages and benefits that can be realized through the use of exemplary embodiments of the present invention. For example, there is no incompatibility between the eNB 12 and the UE 10 with respect to which rate-matching mode is used in the presence of CSI-RS transmission and/or RE muted. Furthermore, the use of the optimized match rate around CSI-RS and/or muted REs is applied as soon as possible. Furthermore, exemplary modalities can be implemented with very little or no DL signaling overhead. In addition, interference due to CSI-RS puncture can be mitigated by UE 10 at the beginning of the RRCJDLE state, or right after entering the state RRC.CONNECTED.
