TECHNICAL FIELD
[0002] Embodiments described herein generally relate to wireless networks. Some embodiments relate generally to interference cancellation in a wireless network.
BACKGROUND
[0003] Wireless, radio access networks (RAN) enable mobile devices (e.g., radiotelephones, cellular telephones, user equipment (UE)) to communicate within that network with a fixed landline infrastructure (e.g., base station, evolved node B (eNodeB), access point). For example, these radio access networks can include WiFi™, 3 rd Generation Partnership Projects (3GPP), or Bluetooth™.
[0004] To improve the capacity of LTE-A networks, deployment of heterogeneous networks to achieve cell splitting gains and Multi-User Multiple Input-Multiple Output (MU-MIMO) are considered. In both scenarios, co- channel interference, either from inter-cell or co-scheduled intra-cell users, is expected to become the dominant limiting factor for achieving higher network capacity. In typical systems, such interference is mitigated by using coordinated multipoint techniques (Co MP) that help to avoid interference at the transmitting base station (i.e., network side). [0005] There are general needs to reduce interference in a wireless network.

DETAILED DESCRIPTION
[0021] The term "base station" may be used subsequently to refer to any fixed transceiver apparatus that may communicate using one or more particular radio technologies. For example, base station can refer to an access point (AP), an eNodeB, or a cell site.
[0022] FIG. 1 illustrates communication systems having intra-cell and inter- cell interference that may use network assisted interference mitigation. The intra- cell system 100 may have one base station/access point 110 that is
communicating with two user equipment (UE) devices 111 , 112. The inter-cell system 101 may have a plurality of base stations 121 , 122 that are each communicating with their respective UE devices 123, 124. Both base stations 121, 122 may be connected directly or via some network entity 130 through a respective backhaul link 140, 141. The UE devices 123, 124 can be affected by interference by the neighboring base station 121, 122.
[0023] Interference mitigation may be performed at the UE side by accounting for spatial properties of the interference. This may provide increased gains in spectral efficiency.
[0024] Further enhancements for interference mitigation at the receiver side should be achieved by considering more advanced receiver algorithms that may utilize additional information about interference structure. For example, receivers could be provided with side knowledge of the interference such as, but not limited to presence of interference, the modulation format, precoding and reference symbols, etc. Such receivers may be considered for performance improvement of different physical channels such as Physical Downlink Shared Channel (PDSCH), Physical Downlink Control Channel (PDCCH), or Enhanced Physical Downlink Control Channel (EPDCCH).
[0025] The present embodiments include advanced receiver structures and corresponding signaling for PDSCH. Different advanced receiver structures (such as maximum likelihood (ML) or reduced complexity ML, codeword level interference cancellation (CWIC), maximum a posteriori probability (MAP) use different levels of signaling support. In the present embodiments, the parameters that should be provided for different receiver structures to facilitate interference cancellation. Other enhancements to approve operation of advanced interference cancellation/suppression receivers.
[0026] The operation principle of CWIC and MAP relies on the possibility of the demodulation and the decoding of the interfering layers a victim UE for the purpose of interference cancellation. The main difference between the two is that the output of the CWIC receiver for interfering layer are hard coded bits, while for the MAP receiver are soft metrics also indicating probability of the decoder decisions. Since the SIC and MAP involve decoding of the interfering layer(s), victim UE receiver should be provided with information about assumptions that were used to generate the interfering signal designated to the UE in the neighboring cell.
[0027] The procedure for deriving a received coded sequence at the eNodeB transmitter, particularly a soft buffer partition and a circular buffer size Nm may be determined by denoting the soft buffer size for the transport block by Nm bits and the soft buffer size for the rth code block by Nc¾ bits. The size Nc¾ may be obtained as follows, where C is the number of code blocks computed:
Ncb = min for DL-SCH and PCH transport channels; and
Figure imgf000006_0001
Ncb = Kw for UL-SCH and MCH transport channels where Nm is equal
KcKMIMomin{MDL HARQ,Miimit
where:
[0028] if the UE signals ue-Category-vlOxy, and is configured with transmission mode 9 or transmission mode 10 for the DL cell, Nsoft is the total number of soft channel bits [4] according to the UE category indicated by ue- Category-vlOxy. Otherwise, Nsofl is the total number of soft channel bits [4] according to the UE category indicated by ue-Category.
[0029] Kc can be determined by the following:
li Nsofl = 35982720, else if Nsoft = 3654144 and the UE is capable of supporting no more than a maximum of two spatial layers for the DL cell,
c = 2
else
Kc = 1
end if
[0030] KMIMO ^ equal to 2 if the UE is configured to receive PDSCH transmissions based on certain transmission modes. Otherwise, KMIMO is equal to 1.
[0031] If the UE is configured with more than one serving cell and if at least two serving cells have different uplink/downlink (UL/DL) configurations, MDL_HARQ is the maximum number of download (DL) hybrid automatic repeat requests (HARQ) processes for the DL- reference UL/DL configuration of the serving cell. Otherwise, MDL_HARQ is the maximum number of DL HARQ processes as defined in section 7 of 3 GPP TS 36.213: "Evolved
Universal Terrestrial Radio Access (E-UTRA); Physical layer procedures". Mumu a constant equal to 8.
[0032] Denoting by E the rate matching output sequence length for the rth coded block, and rv;^ the redundancy version number for this transmission (rvidx= 0, 1 , 2 or 3), the rate matching output bit sequence is e¾, where k = 0,1 ,.. 1 .
[0033] Figure 2 illustrates soft buffer partition. It can be seen that the coded bit sequence depends on: UE-Category-vlOxy, UE capability of supporting two spatial layers for the DL cell, number of HARQ processes, and number of configured cells in CA.
[0034] As these parameters are UE-specific some ambiguity may occur at the victim UE for the decoding of interfering layers. One or more solutions to this problem are discussed subsequently.
[0035] In an embodiment, an indication is made to the UE information about HARQ soft buffer partition by configuration of one or multiple sets which includes parameters: {ue-Category-vlOxy, UE capability of supporting two spatial layers for the DL cell, number of HARQ processes, number of CCsJ by radio resource control (RRC). Then by means of downlink control information (DCI) signaling dynamically indicate the particular set that should be used for the decoding of the interfering layer. In case of single set configuration the DCI based signaling may not be used.
[0036] In another embodiment, the victim UE is assumed to be the same { ue-Category-vlOxy, UE capability of supporting two spatial layers for the DL cell, number of HARQ processes, number of CCs} parameters as the one which are used for the decoding of the serving signal.
[0037] In another embodiment, configure default { ue-Category-vlOxy, UE capability of supporting two spatial layers for the DL cell, number of HARQ processes, number of CCs} which should be used for the decoding of the serving and interfering layers. Configured { ue-Category-vlOxy, UE capability of supporting two spatial layers for the DL cell, Number ofHARQ processes] may not exceed current UE capability.
[0038] In order to improve the interference suppression/cancellation performance the maximum likelihood receiver should be capable of processing more spatial layer than number of receiver antennas. For example, the victim UE with two antennas should be able to process three or larger number of spatial layers using maximum likelihood criterion. For the UE with maximum three layers processing the layer partition between serving and interfering nodes can be e.g. as follows:
{Number of serving layer 1, Number of interfering layers 0, 1 or 2}
{Number of serving layer 2, Number of interfering layers 0 or 1 }
[0039] To support such receivers (capable of processing larger number of streams than receiver antennas) at least two modulations schemes corresponding to up to two interfering layers should be signaled to the UE. The indicated modulation could be {Spare, QPSK, 16QAM, 64QAM} , where 'Spare' may indicate empty physical resource block (PRB) pair.
[0040] Per PRB pair and per layer assignment of the modulations can be broadcasted in the DCI transmitted in the common or UE-specific search space as shown in the table of FIG. 3. Modulation assignment can be also signaled for the PRB sets comprising a plurality of adjacent PRB pairs. [0041] In another embodiment, each modulation of the PRB set can be indicated to the UE as indicated in FIG. 4. FIG. 4 illustrates a table of the various modulation assignments for the PRB pairs for each interfering layer (e.g., layer 1 , layer 2). Each PRB is a bitmap, where ones (or zeros) in the bitmap may indicate that particular PRB on the particular layer carriers PDSCH with the indicated modulation (e.g., 'Spare' , QPSK, 16QAM, 64QAM).
[0042] To facilitate measurement of the channels corresponding to serving and interfering nodes, were one of the node may use more than one spatial layer, the UE-specific RS should support up to four orthogonal antenna ports across neighboring cells. In an embodiment, UE-specific antenna port 7, 8 and 11 , 13 (with orthogonal cover code (OCC) length 4 processing) may be used for orthogonal UE-specific scheduling of the PDSCH transmissions in the neighboring cells with up to two layers. The indication of which UE-specific antenna ports are to be used for PDSCH may be signaled with the help of additional bit(s) in the DCI format 2C/2D (or other formats based on DCI format 2C/2D). This bit may be used to dynamically switch between legacy and new {Antenna port(s), scrambling identity and number of layers indication} combinations. FIG. 5 illustrates a mapping table for legacy antenna ports, scrambling identity, and number of layers indication. FIG. 6 illustrates a mapping table of new antenna ports, scrambling identity, and number of layers indication of the present embodiments.
[0043] In another embodiment, the 4 orthogonal UE-specific RS across neighboring cells for PDSCH with up to two layers can be achieved by using antenna ports 7, 8 and 9, 10 (with OCC length 2 processing and frequency division multiplexing) in the neighboring cells. An antenna port(s), scrambling identity and number of layers indication mapping table illustrating such a concept is illustrated in FIG. 7.
[0044] In another embodiment, a new DCI format (e.g., DCI format 2E) can be defined to support channel estimation on serving and interfering signals. In this case the tables illustrated in FIGs. 5 and 7 may be merged into a signal table that uses 4 bits for antenna port(s), scrambling identity and number of layers indication. This merged table is illustrated in FIG. 8. [0045] Assuming that interference cancellation receiver can only be used for PDSCH reception with no more than 2 layers, the antenna port(s), scrambling identity and number of layers indication can be represented as 3 bits as illustrated in FIG. 9. In such an embodiment, it may not be necessary to newly define or change the existing DCI format(s).
[0046] In some of the embodiments, PDSCH RE mapping may be performed either assuming mapping of UE-specific antenna ports 7, 8, or antenna ports 9, 10 or antenna ports 7, 8, 9, 10, depending on the additional configuration signaled from the network.
[0047] In another embodiment, by using RRC signaling, the network may configure one table for antenna port(s), scrambling identity and number of layers indication out of two available, as shown in FIGs. 10 and 11 , that may be used by the UE-specific RS processing. Depending on the RRC configuration, either antenna ports 7, 8 or 11 , 13 or 9, 10 can be used to transmit one or two layer PDSCH.
[0048] To improve the channel estimation performance for UE-specific reference signals on interfering layer, a PRB bundling assumption for UE- specific RS of interfering layer(s) may be configured for the UE using RRC signaling.
[0049] For some receivers, it may be desirable to signal PDSCH resource elements (RE's) mapping used on the interfering layers. In such an embodiment, the network may configure for the UE (using RRC signaling) one or more sets that includes the following parameters: {PDSCH start, ZP CSI-RS, NZP CSI- RS, MBSFN sub frames, CRS configuration}. The particular set used by interfering node for PDSCH transmission may then signal in DCI using IPQI bits (interfering PDSCH RE mapping and Quasi co-location signaling). For some receivers it may be desirable to signal PDSCH REs mapping used on the interfering layers. In such an embodiment, the network may configure for the UE (using RRC signaling) one or more sets that includes the following parameters { PDSCH start, ZP CSI-RS, NZP CSI-RS, MBSFN subframes, CRS
configuration} . The particular set used by interfering nodes for PDSCH transmission may then signal in DCI using IPQI bits (interfering PDSCH RE mapping and Quasi co-location signaling).
