Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may identify, when using carrier aggregation and a plurality of component carrier groups, first traffic associated with a first service type and second traffic associated with a second service type for concurrent transmission. The user equipment may transmit, concurrently, the first traffic associated with the first service type using a first component carrier group of the plurality of component carrier groups, and the second traffic associated with the second service type using a second component carrier group of the plurality of component carrier groups. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless communication device may generate a Reed Muller generating matrix for an information bit vector that includes a plurality of information bits. The wireless communication device may remove, from the Reed Muller generating matrix, a row vector consisting of all 1-values to form a modified Reed Muller generating matrix. The wireless communication device may encode the information bit vector using the modified Reed Muller generating matrix to form a codeword. The wireless communication device may transmit the codeword without transmitting a pilot signal or demodulation reference signal for the codeword. Numerous other aspects are provided.

Abstract: Aspects are presented which enable a UE to determine a supplementary uplink (SUL) configuration for an uplink cancellation indication (ULCI) for cancelling uplink communications in SUL. The UE receives from a base station a first configuration associated with a first block of an ULCI and associated with at least one of a SUL carrier a non-supplementary uplink (NUL) carrier in a cell. The base station configures the UE with a second configuration associated with a second block of the ULCI and associated with a SUL carrier in the cell, and the UE determines the second configuration. The UE monitors the ULCI based on the first configuration and the second configuration.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless communication device may determine that a first set of downlink control information (DCI) formats is associated with a same DCI size as a second set of DCI formats, and perform a padding operation so that the first set of DCI formats and the second set of DCI formats are associated with different DCI sizes. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit a sounding reference signal (SRS) on a plurality of antenna ports. The UE may transmit the SRS on one or more virtual antenna ports, the one or more virtual antenna ports being based at least in part on the plurality of antenna ports. Numerous other aspects are provided.

Abstract: A user equipment (UE) sends an indication supported combinations of sounding reference signal (SRS) resources, unsupported combinations of SRS resources, or compatible SRS resources to a base station. The base station selects one or more SRS resources for the UE from the SRS resources that are supported by the UE or are compatible for the UE. In some examples, the UE receives a configuration from the base station for multiple SRS resource sets. After configuring the UE with multiple SRS resource sets, the base station selects one of the SRS resources sets, and may indicate the selected SRS resource set to the UE. The UE transmits a physical uplink shared channel (PUSCH) to the base station using SRS resources from the selected SRS resource set.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive activation or reactivation downlink control information (DCI) for a semi-persistent scheduling (SPS) configuration, wherein the activation or reactivation DCI includes a downlink association index (DAI) that is incremented by: a value of one to represent an initial SPS communication associated with the SPS configuration, or a value equal to a number of SPS occasions that are multiplexed in a same physical uplink control channel (PUCCH) communication. The UE may transmit acknowledgement or negative acknowledgement (ACK/NACK) feedback in the PUCCH communication based at least in part on the DAI. Numerous other aspects are provided.
