    APPARATUS AND METHOD OF RECEPTION, AND, APPLIANCE AND METHOD OF TRANSMISSION
    The present invention relates to methods and equipment for configuring search space and for searching space channel structure for signaling control information.
    Third generation (3G) mobile systems, such as universal mobile telecommunications systems (UMTS) standardized within the third generation partnership project (3GPP), have been based on radioaccess technology for multiple band code division access (WCOMA). Today, 3G systems are being applied on a large scale around the world. After emphasizing this technology through the introduction of high speed packet access (HSDPA), also called high speed reverse link packet access (HSUPA), the next main step in the evolution of the UMTS standard brought the combination of a multiplexing orthogonal frequency division (OFDM) for downlink (direct access) and multiplexing access for single carrier frequency division (SC-FDMA) for uplink (reverse link). This system was called long-term evolution (LTE), as it aims to adapt to future developments in technology.
    The LTE system represents efficient packet radio access and radio access networks that provide full IP-based functionality with low latency and low cost. Detailed system requirements are given in 3GPP TR 25.913, Requirements for evolved UTRA (E-UTRA) and evolved UTRAN (E-UTRAN), võ.0.0, January 20 09, (available at http://www.3gpp.org / and incorporated herein by reference). Downlink supports QPSK, 16QAM, and 64QAM data modulation schemes and Uplink supports BPSK, QPSK, 8PSK and 16QAM.
    access to the LIE network must be extremely flexible, using a number of channel bandwidths defined between 1.2s and 2y MHz, centrastadú with fixed channels of 5 MHz (UTBà} : terrestrial radio access - 2MTB. The spectral efficacy is increased was up to four wz cmiparous with UTRA, and improvements in architecture and signaling reduce roundtrip latency.The antenna technology, Multiple Input / Output (MIMO) should allow lu times more users per cell than the WCOMA original technology gives radio access, from 3GPP. To adapt the maximum allocation arrangements of ..... powavel frequency, both the band operation, paired (duplex frequency division FDsj and the band operation using pareads (TED duplex frequency division), LIE can coexist with previous 3GPP radio technologies, even on channels adjacent to the calls: can be addressed and received from all previous ranloac technologies esso 3GP2.

    Q data is mapped into 1: 0 physical resource blocks via pairs of virtual resource blocks, a pair of virtual resource blocks is mapped to a pair of physical resource blocks. The following two types of virtual resource blocks are defined according to their mappings in the physical resource block in downlink 111:
    .25 ~ Localized Virtual Resource Block ÍLVRB} ~ Distributed Virtual Resource Block (DVRBj
    In the transmitter mode located using the local VRBs, the: edB has total control, if which and how the resource blocks are used, it is d-sve Use this control 30 normally to harvest resource blocks which result in a great efficiency spectral, In most mobile control systems, this results in adasocute blocks of smooth resources or multiple clusters of adjacent blocks of physical cars and transmission to a union user equipment, because the radio channel is coherent in the frequency domain, implying that if a block of physical resource 5 offers a great spectral efficiency, then it is very possible that an adjacent physical resource block offers a similar great spectral efficiency. In the distributed transmission mode using the distributed VRBs, the blocks of physical resources that carry data to it: Π & are distributed 10 in the frequency band to reach at least some blocks of physical resources that offer a spectral efficiency sufficiently large, thus obtaining the diversity of photography.

    One of the main features of LEE is the ability to transmit multicast or broadcast data from multiple cells on a standardized single frequency network 5, which is known as a single frequency multimedia broadcast network operation. In MBBFN operation, the: U'E receives and copbin synchronous signals from multiple cells. To facilitate this operation, the UE needs to perform an estimate: of separate channel based on an MBSFN reference signal. Ear to 10 avoid mixing a reference signal: MBS FM with the normal reference signal in the same subframe, certain known subframes of the MBBFM subframes are reserved from the MFSFN transmission.

A donor edede (d-eõBj 41S directly serves a: da equipment user UE1 415 and one on relay (RU) 320 which still serves PB 2. 425. The link between the donor B 15 et 4:10 and relay node 420 is typically referred to as the Basifnaul of the upifni / docnliai relay. between relay node 420 and user equipment 425 attached to the relay node (also indicated camp r-UBs) is called an access link (relay).
    Donor C- edodoB transmits L1 / L2 data control 20 to the ÜE1 415 user computer and also to the relay node 420 which still relays the control and the 11 / X2 data to the UB2 425 user equipment. 0 ne relay can operate in the so-called multi-time action mode, in which case the transmission and reception operation cannot be done at the same time. In particular, if q link from abodeB 410 to relay node 420 operates on; same frequency spectrum as the relay node link 420 for UE2 425, due to the relay transmitter causing interference with my own receiver, simultaneous edodeB-to-ne relay transmissions and ~ to ~ ÜP relay in the same 30 frequency resources ask for no possible, unless sufficient isolation of the output and input signals is provided, when the relay node 420 transmits the edodeB
    fixed to na reié. Siri lly, when a 42D relay node receives data from the doaoor eNcdeE, it cannot transmit data to the ÜEs 425 attached to the ne relay. Thus, there is a subframe division between the relay backhaul link and the 5 relay access link.
    How do you support the relay nodes, m 3GP it has now been agreed that:
    - The sGbquadro® of the direct access backhaul of the relay during which the eNodeB is configured for the transmission of the direct access backhaul of the relay, are 1 n d i a d of the information and rr 1 and s t tios.
    - The subframes of the direct link backhaul of the relay during which the transmission of the direct access hackhaul inlé-to-edodeB is indicated in a semi-static or implicit way · obtained by tsharreaction HARQ timing of the subframes of the direct link backhaul of the role.
    ~ Nos: direct access backhaul subframes of the relay., A transmit® relay node for the donor Nodes and consequently the r-üEs are not expected to expect to receive any data from the rabble node. To support backward compatibility for UUs that are not yet aware of their connection to one on the içomu relay: qs EU »Version 3, for which a nb relay appears to be a standard éNodeB, the relay node ednfigures direct access backhaul subframes as EBEFE subframes.
    Next, a network configuration is assumed as shown in Figure O for exemplary purposes 0 ehcdeB duadur transmits control and data ld / Ll for the user equipment (XBÍ ie 4.10 also, for c reXê (nê relay) 420, and the relay node: 420 transmits control and L1 / L2 data to equipment 30 relay-user used.) 425 * Supposing that the relay node operates in a time duplex mode, that is, the transmission operation is reception not are performed at the same time. Whenever the relay node is in mode : 'tr an sort ir, α 2E2 needs to receive the control channel © 51 / .1,2 to the shared physical channel- direct access (PDSCH ;, whereas when the no grating is sa mode '' receive, that is, is receiving: the channel of: control 11/12 and PDSCH of ho B, alo pods transmit t go to UBS and, therefore: ü £ 2 cannot receive information dc relay node in this sub-block of the case was that the UE2 does not know that it is attached to the relay node (for example, a DD Version S (, the relay node 420 must behave like a normal e-iFadeB. As will be understood by the technicians in that matter, in a switching system without the relay node, any user equipment can always assume that at least one Li / 1.2 control signal is present in any subframe. To support this user equipment operating below one in the relay, the relay node must, therefore, simulate this expected behavior in all subframes,
    As shown in Figures 2 to 3, each downlink subframe consists of two parts, the control channel region and the data region. 1 Figure 5 illustrates an example of the configuration of mbsfn frames in the relay access link in situation-, in which the relay backhaul transmission occurs. Each subframe comprises one part of the control data 510, 520 and a part of data 530- , 540. The first CFDM 720 symbols in a MbSFF subframe are used by relay node 420 to transmit control symbols to r-lJEs 425. For the remainder of the frame, the relay node can receive data 540 from donor B 410. Thus , there can be no transmission from relay node 420 to r-lE 425 in the same subframe, 0 r ~ UE receives the first, up to two symbols from the OFbM control and ignores the remaining part of: subframe, Subframes not MBSFk are transmitted over rule node -42 0 for r-DF 525 and cent role symbols 51-5, as well as data symbols 530 are processed in r-UE 425. A subframe. MB3FN can be configured to anything 15 ms in each 40 mA. Therefore, the backhaul subquaers for direct access to the relay also open up both 10 ms and 4 ms (4 ms, be : siMlaT form to the configuration of EBSEN sub-frames, the direct access hackhaul sub-frames of the relay cannot be configured in the sub-frames with #Q # 4 r # 5 and # 9. These subframes that can be configured with 5 subbasic DL sub-arrays are called 5 illegal DL sub-arrays 7 '. Thus, DL backhaul relay subframes can be »gtwi.s or MB3FE sub-frames on the side d-eNB. It is currently accepted that the DE backhaul relay subframe, during which the eNE 410 direct access backhaul transmission to relay 410 can occur, are indicated in a systematic manner. direct link backhaul transmission from relay node 420: for p eNB 410 to occur, they are Indicated in a semi-static or impistic way obtained by HARQ temporization of the DL hackhaul relay subquadrcs.
    How the hBSEN subframes are configured: in the relay IS nodes as direct access backhaul sub frames of direct soesse :, the relay node cannot receive OECCH from the donor etodeB. Therefore, a new physical control channel (OP-BDCCH) is used to indicate dynamics or 'foend.-persistently w resources among the s ul quads those indicated in a semi-tactical way for data 20 direct access and direct link backhaul. Direct access hackhaul data is transmitted in one. new channel, physical data (R-PDSCH; and direct link backhaul data is transmitted on a new physical channel and given fR-PUSCH). Ort; RPDcClhs; for the relay node they are mapped in an R-FDCCH 2δ region within the PDSCH region of the subgroup. The new relay expects to receive E ~ FoCCk within the subframe region. In the time domain, the R-PDCdH region extends the configured direct access backhaul subframes, in the frequency domain, the R-PDCCH region exists in certain: pre-configured resource blocks for the 30th highest signal relay in the layers. Regarding the project $ ac use of an R-ãoCCH region within a subquadron, they have been determined. the following features in the pad tool ration:
    ~ Q R-PDCCH is indicated for BBBs for airtight transmission. In addition, the set of resources currently being used for 5 , traaamis-sâo. B-PúCCH dentins of the semi-static PPBs mentioned above can vary dynamically between sub-subgroups,

    ~ Nc casc <of the MRSFN sub-classes, the relay transmits the control signals: to the r-UEs. Then, it may be necessary to switch to the transmission mode for the reception, so that the relay node can receive the data transmitted by the donor eNodoB 15 within the same subframe. In addition to this failure, the delay in signal propagation between the donor eNodoB and the na sweet roll be taken into account. Thus, the F-PDCCH is first transmitted starting from an OFDM symbol that, within the subframe, is significantly delayed before the country receives it.
    - The mapping of the R-FDCCH in the flisca resources can be done either in a distributed way in the frequency w in a hollow shape. 11 h in the f r e q uen oi.

    Thanks to the design of the search space, of the present invention, it is possible to avoid the complexity by giving total flexibility, providing sufficient choices for the different 25 scenarios with a limited number of blind decoding experiments.
    Next: the legacy of the PuCCE concept is supposed to be reused, that is, an eFDCCü is the aggregation of il, 2, 4, t) eCCFe. A FAB: pair is also supposed to be divided into 30 four eCCEs.
    With reference to Figure 5, the number of different canaries could be defined as follows. According to the position of the EP :, there are gr 1 mainly behind scenarios:
    1. g Slfíl scenario comprising cell center UEs, which can be configured, for example, with a lower level of candidate aggregation;
    2 »the SlOc scenario with overcoming cell ws can be configured with a certain higher level of candidate aggregation and a certain lower level of candidate aggregation;
    3, the old2 scenario can be configured with a higher level of candidate aggregation; a à meson: time, according to cos ..... the feedbacfe W, there are mainly three scenarios:
    i. the scenario 5201 comprising c W with more accurate feedback, for example, moving at low speed, greferenoialmsnte using local candidates!
    il. the 5202 scenario comprising d W. with less accurate feedback, for example, moving at high speed, pm f a r en ç j. a ç. ç'én u s an a ca n d 1 d act u i st r 1 bu i ds; and the sanario unio3 comprising the UE with feedback
    each possible combination can cause a blockage · Also, this approach makes it difficult to package different PCI messages within the same PR3 pair.
    For example, with reference to Figure f, Corsican UE1 and UE2 can be seen, both being, for example, medium bFs.
    in this situation, only spatial multiplexing, Cpma indicated in the figure, is possible, locating the UE1 for APS to UE2 for ÃP7. However, if there are many types of these ÜEs in the system, the blocking between search spaces becomes more and more critical 5 ,
    This can be improved by providing a plurality of search patterns having a certain number of candidates for one or more levels of aggregation in order to avoid overlapping search patterns at the same level of aggregation 0 for at least two patterns.
    more specifically, Figure 7 schematically illustrates two patterns, pattern 0 and pattern 1, according to an embodiment of the present invention.
    In particular, in Figure 7, the horizontal axis 5 represents the VRB index; α vertical axis represents 0 value
    AF while the remaining axis represents the level of aggregation. The two patterns 0 and 1 each comprise a plurality of candidates arranged at any level of aggregation levels 1, 2, 4 and / or 3. As can be seen, the pattern Ú has 0 candidates at the level of aggregation 1 and at howl of aggregation 2.
    Similarly, pattern 1 also has candidates in aggregation howl 1 and in aggregation howl 2. Besides. in addition, the two patterns are designed in such a way that they are not suppository. In particular, the mapping of candidates at aggregation level I 5 of pattern 0 does not overlap with candidates at aggregation level 1 of pattern I. Similarly, the mapping of candidates at level i aggregation of level 0 does not overlap with that of candidates at aggregate level 2 of standard 1 <
    Alterúãtivamsnte cu, Alem said, the patterns 0 and 1 are 0 designed so that the same levels of aggregation and the corresponding number of candidates are present. Alternatively, or, moreover, the mapping of candidates to complementary eCCEs in the sides of the respective aggregation levels, that is, the eCCE® of aggregation level 1 in the G pattern, are used for aggregation level 1 in the standard 1, and similar to the aggregation level 1.
    Defining pattern 0 and pattern 1 in this way, 5 c packaging is done, that is, multiplexing, of different SCI messages in the same: PRE, since the standards do not overlap, In particular, it is possible that the indications DL and UL for the same DE are transmitted in the same PRE pair. In addition, both standard 0 and standard 1 define the number of candidates in museums at the aggregate levels, they can be applied to different UEs in the same scenario, for example, they could be applied, respectively, to UE1 and ÚE2 of the Figure B, without overlapping ·. This gives greater flexibility while the number of possible active UEs can be increased without arising blocks on the 15 channel.
    Alterratically, or, in addition to Figure 1, B illustrates schematically another criterion for defining another search pattern, in accordance with an embodiment of the present invention.
    In particular, pattern 0 in Figure B corresponds to the pattern Q already defined in Figure 71 Q Pattern 3, is polished: in Figure 3 and constructed in order to provide candidates with a higher level of aggregation, collected with α pattern Ú, also providing Candidates without overlapping at aggregation level 2 compared to standard 0. This gives a : possibility of using standard 0 and standard 23 at the same time.
    In addition, this allows DCI messages from EVs configured with: candidates with a higher level of aggregation to be multiplexed with the messages ECI dbs DEs oonfígurais cam candidates of lower level of aggregation. Even in the same 30 BE, candidates for aggregate assets 1, 2 and 4 can be co-dependent so that the ÜS search space does not need to be reconfigured, even if the EU scenario changes,
    Furthermore, this project is advantageous, as it allows different patterns: to have candidates in different aggregation levels. For example, cell center patterns can be associated with patterns having candidates with a mere level of aggregation, such as the pattern 0 »At the same time, 5 cell edge IBs can be associated with patterns having candidates with a higher level of aggregation aggregation, as standard 3 »Thus, with a limited number of blind deucdification experiments, different can be configured with different numbers of candidates with a lower level of aggregation and candidates with a higher level of aggregation.
    Aiternatively ,: or, moreover, s. Figure 3 schematically illustrates another criterion for the definition of another search pattern, according to: according to: an embodiment of the present invention,
    In particular, Figure 3: illustrates a pattern <1. in which only candidates of a higher level of aggregation are used, this approach gives an advantage that the spatial and / or frequency diversity can be obtained, at least stops with a higher level of aggregation, as in the mode. In addition, another benefit is that since candidates of aggregation level 2.20 can easily block candidates from other aggregation levels, pattern 4 can always be configured on another antenna port to avoid blocking candidates from other aggregation levels .
    Although in the real1 sections only 25 patterns were defined: search, the present invention is not limited to these and the number of patterns can be increased or reduced, constructing: other patterns according to the rules presented above <
    Figure 10 illustrates, schema ti the lover to provide information on five search patterns according to an embodiment of the present invention.
    As can be seen, patterns O and 1, as well as patterns 2 and 3 offer complementary candidates. This, in turn, allows the packaging of different DÇI messages nòfsj same is; PRBís}. In addition, Q: and 1 standards will offer candidates with a lower level of aggregation, while Standards 2 and 3 offer principal candidates for higher levels of aggregation. This is beneficial, since with a limited number of blind decoding studies, different UEs can be configured with different numbers of candidates with a lower level of aggregation and candidates with a higher level of aggregation. In addition, pattern 4 offers candidates for AL 3, so that spatial and / or diversity. iffequêncíá can be obtained at least for the aggregation spike as the fallback mode. In addition, it can be seen that the standards are such that the applicants did not overlap at the same level of aggregation.
    When using the search patterns as described above, it is possible to define a search space by configuring the patterns with the following parameters:
    -standard 10, as the standard 0, I, 1 and / gu 3, cmg above d and fines; and / or
    - port: antenna, determining which dm-re 20 ports are used to demodulate: ó: ePECCH; and / or
    - PB set, determining which iBc eCCEs should be detected in; and / or
    - Diversity framework, detfôtfiii.near if, for example, EVRB, DVRB, 3ESC ceo used for mapping in the
    2E RRB.
    In particular, the antenna port can be used to define the üh-RB port, the pattern being mapped to ueti.n, thus going to spatial domination. The advantage of this parameter is that it offers the gain of special programming, allowing 3u thus broader channels in the space domain and offering the possibility of more: candidates to avoid the blockade. The RB set can be used to determine in the set ò and RBs the pattern being mapped, thus defining the frequency domain. The advantage of this parameter is that it offers a range of frequency programming, thus allowing more candidates in the frequency domain and offering the possibility of also more candidates avoiding bioqueao. flnalmaute, the diversity configuration can be used to determine, for example, whether LvRB, WBB, SFEC are used for mapping in PRB. The advantage of this parameter is that it offers spatial diversity and / or gives frequency when the channel is not known as, for example, when a selective programming of frequeue1a / sewage is not possible.,
    An exemplary configuration is illustrated schematically in Figure 11, according to a realization of the present invention.
    In particular · .. the configuration comprises:
    - a UB1 being a half cell ÕE with accurate feedback, as the case of Figure B, and configured with c pattern 3 in AR3, in distributed mode, and Pattern 4 in AP7 in distributed fear, * and
    - a 0E1 being half a cell with feedback. The least accurate, core in the case of Figure S, and configured with c pattern 2 in APB, in distributed mode, and Pattern 4 in : AP7 in distributed mode.
    Thus, the PEI and UE2 being in similar conditions ask to use complementary standards, in order to obtain the same 5 performances. Sketches in this color: figuration, candidates Ai-2 and AL 4 from search spaces EE1 and UE2 can be multiplexed within a PRB pair, since patterns 2 and 3 are complementary. Thus, this allows for empathy with other words, the multiplexing of different DPI ü noÇs messages; same (s; PRSís}. At the same time, there is no blocking of candidates AI.2 s Al4 from PEI to PEL. In addition, pattern 4 contains two AL3 candidates, so there is no blocking of AIG candidates from 3El to BB2. Furthermore, as candidates

    Alternatively, or in addition, an applicable set of subframes can be added to the search space configuration, thus also providing diversity in the time domain. In particular: <- · <: 00: 0 :: - ^ SUÇmarirOSíííd: .aU-ta, :: 1 :: 000: 01: 000: 0: 0 :: 0: 0 ::, :::,: 0: /: ©: U : tqUanqO :: the common search space needs to be monitored ·, can be configured: a greater number of candidates with a higher level of aggregation, that is, of ; patterns while

    As an example ·, the set of subframes can be 20 l. Connected to seboon definitions together for CSI communication <Alternatively, or, in addition, the subframe set can be linked to low power ABS subframes and BBS subframes not low power.
    Figure 12 illustrates another design pattern separated by 25 levels of aggregation according to an embodiment of the present invention.
    in this resuscitation, standards are designed and refined with levels of aggregation. In particular, each pattern contains candidates at one level: aggregation. In addition, pure levels of aggregation X, 2 to 4, there are two patterns which are complementary to each other. In addition, the figure illustrates, to the right of each pattern, a corresponding number of candidates, anno Umi:
    This solution proves: it benefits from a more flexible combination and the çpnf i.guration of the standards.
    Figures 13 and 14 illustrate these techniques and search pattern configurations in accordance with other embodiments of the present invention.
    In particular, in Figure 13, a cell center UE with feedback mends is configured with the 0 η X pattern in Figure 10, with distributed transmission. In particular, the upper part of Figure 13 illustrates the two patterns:
    ·· SSI: thief O, AP 7, VRB set õ, DVRB
    - S33 ·: Standard A AP A VRB set q, DVPB while the bottom of Figure 13 illustrates the resu 1Can configuration. you.
    In addition, in Figure 14, a ΠΒ of cell center with. less feedback is configured with the A 3 ® 4 standards in Figure 10, with. distributed transmission. <Fm particular, the top part of Figure 14 illustrates the three patterns:
    - 337: Pattern 2, ÜP 7, VRB: set 0, DVFB - S32: Pattern 3, AP 7, VRB set 0, WRB ~ 33 3: Pattern The AP 3, VRB set d, PVRB

    In particular, in Figure 15, all candidates within a pattern do not overlap, so there is no candidate block within a pattern. Alternatively, or in addition, he said, the standard 0 and 1, as well as G and 3, have complementary candidates. Alternatively, the level of aggregation 3 in standard 3 and the level of aggregation 1 in standard 0 offer complementary candidates,
