Abstract: Various aspects of the disclosure relate to rate matching techniques for block encoding. In some aspects, a decision regarding whether to use repetition-based rate matching or puncture-based rate matching is made based on a block size of information being encoded. In some aspects, repetition-based rate matching uses a bit-reversal permutation technique.

Abstract: In conventional wireless communication systems, only a single transmit precoding matrix indicator (TPMI) with a single associated sounding reference signal (SRS) resource indicator (SRI) is configured/activated in downlink control signal (DCI) for retransmission of data. To enable better performance in retransmission, the UE may dynamically turn on/off/switch panels for retransmissions.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may determine an automatic gain control parameter, for a group of downlink symbols associated with a base station, based at least in part on an automatic gain control resource included in the group of downlink symbols. The user equipment may perform, based at least in part on the automatic gain control parameter, automatic gain control for one or more data symbols included in the group of downlink symbols. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may perform channel state information measurements on reference signal transmissions from a base station. The UE may identify a set of cross layer coefficients associated with a set of spatial layers based on the channel state information measurements. The UE may additionally identify a set of precoding coefficients associated with a spatial layer from the set of spatial layers. In some implementations, the set of precoding coefficients may be based on the set of cross layer coefficients. In some examples, the UE may transmit the set of cross layer coefficients and the set of precoding coefficients to the base station.

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: Methods, systems, and devices for wireless communications are described. In some systems, a user equipment (UE) may report basis subset selection for a set of beams, where the basis vectors are used for frequency domain compression. To reduce reporting overhead, the UE may transmit two reports indicating the basis vectors. The first report may include first information for the basis vectors and is of a known payload size to both the UE and a base station, while the second report may include second information for the basis vectors and may have a payload size dependent on the first information. The base station may decode the first report and may use the decoded first information to decode the second report. Based on the first and second information, the base station may determine the reported set of basis vectors to use for frequency domain compression and may determine non-zero precoding coefficients.

Abstract: Certain aspects of the present disclosure provide techniques for indicating a preemption of resources impacting a joint transmission from multiple transmitting entities to a user equipment. The transmitting entities may be associated with a virtual cell ID or a demodulation reference signal (DMRS) port group ID.

Abstract: Methods, systems, and devices for wireless communications are described for configuring contention-free uplink resources and contention-based uplink resources as preconfigured uplink resources (PUR) available for a user equipment (UE) to transmit one or more uplink transmissions without a specific allocation for the uplink transmission from a base station. Each of two or more UEs may be configured with separate portions of contention-free PUR that each UE may use to transmit a relatively small first uplink communication that provides an indication that the UE will transmit a relatively larger second uplink communication using contention-based PUR. The UE may transmit a buffer status report (B SR) using the contention-free PUR. The first communication may provide an indication of one or more physical layer parameters associated with the second uplink communication. The UE may transmit the second uplink communication using the indicated one or more physical layer parameters via the contention-based uplink resource.

Abstract: Aspects of the disclosure relate to wireless communication systems configured to provide techniques for multiplexing dedicated control information for a plurality of users in a single information block and polar coding the information block to produce a polar code block of dedicated control information for transmission over a wireless air interface. The information block may further include group cyclic redundancy check (CRC) information for the information block and individual CRC information for each dedicated control information.
