    Abstract: Enhanced hybrid channel state information (CSI) reference signal (CSI-RS) for full dimension multiple input, multiple output (FD-MIMO) is discussed in which a base station configures a first CSI-RS resource for non-precoded CSI-RS and a second CSI-RS resource for beamformed CSI-RS. The first and second CSI-RS resources are associated with the same CSI process in a hybrid CSI-RS operation. The UE provides a first CSI report including a first rank and precoding matrix indicator (PMI) based on measurement of the non-precoded CSI-RS. The base station may use this first CSI process. CSI report for the beamforming of the beamformed CSI-RS. The UE further provides a second CSI report including a second rank, second PMI, and CQI based on measurement of the beamformed CSI-RS. Additional aspects may provide for a base station to aggregate multiple two-port CSI-RS resource configurations into a single multiport CSI-RS resource configuration that may be dynamically shared between different UEs.

    Abstract: An apparatus and method for communication including determining an assignment for one of a plurality of symbol durations in a format combination; determining if at least one bit from one or more first upper channels is available if the assignment is associated with the one or more first upper channels and occupying the one of the plurality of symbol durations with the at least one bit, or if unavailable, occupying the one of the plurality of symbol durations with at least one bit from one or more second upper channels or another first upper channel, wherein the first upper channels and the second upper channels are different; and disabling transmission of format information; or including enabling a BTFD hypothesis testing mode; receiving one or more symbol durations on a physical channel; and attempting to decode the received symbol duration with a first hypothesis that a DCCH channel is not transmitted.

    Abstract: Aspects of the present disclosure relate to wireless communication. In some aspects, a user equipment may determine at least one of: a first number of coefficients to be included in a first set of coefficients in a transfer domain that characterize compressed channel state information (CSI) for a first layer, or a first quantization scheme to be used to interpret the first set of coefficients. The UE may determine at least one of: a second number of coefficients to be included in a second set of coefficients in the transfer domain that characterize the compressed CSI for a second layer, or a second quantization scheme to be used to interpret the second set of coefficients. The UE may transmit a report that identifies the first set of coefficients and the second set of coefficients based at least in part on the determination(s). Other aspects are provided.

    Abstract: A method of wireless communication performed by a user equipment (UE), the method including: receiving an indication of uplink (UL) precoding information, wherein the UL precoding information includes a set of frequency domain (FD) bases and coefficients applied to one or more antenna ports; determining a size of the FD bases based at least in part on an item selected from a list consisting of: a dedicated indication, a frequency resource allocation of an UL channel, and an UL bandwidth part (BWP); receiving a grant of a physical uplink shared channel (PUSCH), wherein a frequency resource allocation of the PUSCH includes a plurality of FD units; and determining precoding matrices for the plurality of FD units based at least in part on entries of the set of FD bases, wherein the entries correspond to positions of the FD bases in a range of a frequency resource.

    Abstract: Certain aspects of the present disclosure provide a technique for parallel distribution matching (DM) encoding. A user equipment (UE) implements the technique to perform a first round of parallel DM encoding using k information bits as input by: 1) segmenting the k information bits into N blocks of information bits, and 2) encoding the N blocks of information bits in parallel with N DM blocks. Each of the N blocks outputs one or more encoded information bits in each of the NDM blocks, and a total number of information bits output by the N DM blocks is less than k. The UE then performs a second round of parallel DM encoding using k′ information bits that were not encoded in the first round of DM encoding. The second round of parallel DM encoding includes a same encoding process as implemented in the first round of parallel DC encoding.
