Abstract: Provided is a method of wireless communication which includes selecting a codebook from a plurality of codebooks in accordance with an antenna characteristic, and transmitting an indication of the selected codebook. Each of the plurality of codebooks is associated with one of a plurality of antenna characteristics. In some designs, channel state information is received from a user equipment. The channel state information may be used to determine downlink scheduling and/or precoding. In some designs, the channel state information may include feedback elements associated with different subband granularity. The feedback elements may also indicate a selection of a subset of precoder column vectors and/or a phase offset between two groups of transmit antennas.

Abstract: A method, an apparatus, and a computer program product for wireless communication are provided in which downlink transmission modes in a wireless network are semi-statically configured for a mobile terminal in multiple-input multiple-output (MIMO) operation. The apparatus provides multiple precoding matrix indicators (PMIs) for a plurality of ranks. The provision of multiple PMIs by the apparatus enables balanced performance among different ranks and avoids less than optimal performance observed when the apparatus provides only a single rank and PMI that are generally not optimal for all transmissions. Feedback configuration information received by an apparatus defines a plurality of channel state information feedback instances conditioned on an admissible rank value. Rank indicators (RIs) and PMIs corresponding to the feedback instances are determined and feedback is provided for the channel state information feedback instances.

Abstract: Aspects disclosed herein relate to channel and interference estimations in a multiple transmission point environment including an eNB and RRHs. In the disclosed aspects, one or more transmission points can signal to a UE to measure channel state conditions based on a first and a second resource pattern. The UE may receive the signaling and perform interference estimation based at least in part on the first resource pattern, and channel estimation based at least in part on the second resource pattern. The UE may generate a channel state report based on the interference and channel estimations, and transmit the channel state report to a transmission point. The eNB may employ the received channel state report in scheduling one or more resources for use by the UE, and may select or adjust network traffic on the first and the second resource pattern, to affect the resulting channel and interference estimation.

Abstract: Transmission of control data by a user equipment (UE) in circumstances following a TDD subframe reconfiguration from an evolved node B (eNB) may result in a conflict with a scheduled transmission of the control data. In one example, a UE may modify periodicity, content, priority, or other aspects of channel state information (CSI) or sounding reference signals (SRS) to resolve any conflicts resulting from a TDD subframe reconfiguration and to ensure transmission of the CSI or SRS. In another example, a UE may detect a hybrid automatic repeat request (HARQ) conflict resulting from a TDD subframe reconfiguration. In such example, the UE may determine and apply a HARQ soft buffer size for a HARQ process or determine and apply a codebook size for a HARQ process in carrier aggregation to resolve such HARQ conflict.
