    Abstract: According to example embodiments, a method for wireless communications by a user equipment (UE) is included. The method generally includes performing channel estimation at a plurality of frequency locations based on reference signals (RS) transmitted from at least one transmission point, computing at least one channel feedback metric for each frequency location, and transmitting the channel feedback metrics to the transmission point. According to certain aspects, a method for wireless communications by a base station (BS) is provided. The BS may receive channel feedback metrics from a UE, calculated at a plurality of frequency locations based on RSs transmitted from the BS. The BS may perform interpolation to determine values for channel feedback metrics for frequency locations between frequency locations of the received channel feedback metrics.

    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: Certain aspects of the present disclosure generally relate to resolving ambiguous user equipment (UE) capability signaling. According to certain aspects, a method for wireless communications by a UE is provided. The method generally includes determining capabilities of the UE to support at least one of multiple-input multiple-output (MIMO) or coordinated multipoint (CoMP) features on different operating frequency bands of a radio access network (RAN), signaling, to a base station (BS) of the RAN, a first combination of capabilities of the UE for a combination of bands, signaling, to the BS, a second combination of capabilities, different than the first combination of capabilities, for the combination of bands, and identifying, based on or more criteria, a particular combination of capabilities to be used to communicate with the BS. In certain aspects, the UE may identify the combination of capabilities to use by applying a deterministic rule.
