Abstract: A method, a computer-readable medium, and an apparatus are provided for wireless communication at a user equipment (UE). The apparatus drops transmission of hybrid automatic repeat request-acknowledgment (HARQ-ACK) feedback for one or more downlink HARQ processes. The apparatus transmits, to a base station, a combined HARQ-ACK feedback triggered by the UE dropping a threshold amount of HARQ-ACK feedback, the combined HARQ-ACK feedback including dropped HARQ-ACK feedback for the one or more downlink HARQ processes.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a downlink control information transmission comprising a resource allocation for downlink traffic and at least one dedicated table bit that indicates whether the UE is to use, to decode the downlink traffic, a first modulation order and a first target code rate corresponding to a first modulation and coding scheme (MCS) table or a second modulation order and a second target code rate corresponding to a second MCS table (a 1024 quadrature amplitude modulation table). The UE may decode the downlink traffic according to the first modulation order and the first target code rate or the second modulation order and the second target code rate based at least in part on at least one value of the at least one dedicated table bit. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine a state associated with a sensing procedure, for sensing availability of a resource, based at least in part on one or more state parameters. The UE may perform the sensing procedure to sense availability of the resource based at least in part on determining the state. Numerous other aspects are provided.

Abstract: A base station may associate multiple user equipment (UEs) with one or more UE groups and generate group common downlink control information (DCI) for each UE group for semi-persistent scheduling (SPS) cancellation, such that group common DCI may be transmitted to UEs of a respective UE group. The base station may associate each of UEs with a respective UE group, wherein the UEs are configured with SPS configurations by the base station, each SPS configuration configuring respective SPS occasions. The base station may further determine to cancel one or more SPS occasions associated with at least one of the SPS configurations, generate one or more group common DCI for the one or more UE groups to cancel the one or more SPS occasions, and transmit the one or more group common DCI to one or more UEs associated with the at least one of the SPS configurations.

Abstract: Aspects described herein relate to receiving, from a base station, an uplink resource grant for transmitting uplink control information, where the uplink resource grant indicates an uplink control information format, bundling a number of instances of feedback in a number of feedback bits, where the number of feedback bits corresponds to the uplink control information format, and where the number of instances of feedback correspond to SPS downlink communications, and transmitting, to the base station and in the uplink control information, the number of feedback bits. Other aspects relate to transmitting the uplink resource grant, and receiving uplink control information based on the indicated uplink control information format.

Abstract: A UE may receive, from a base station, a first configuration associated with transmitting a low priority UL channel and a second configuration associated with transmitting a high priority UL channel concurrent in time with the low priority UL channel. The UE may cancel the transmission of the low priority UL channel to transmit the high priority UL channel independently, or multiplex the low priority UL channel with the high priority UL channel to transmit both the low priority UL channel and the high priority UL channel together based on a third configuration received from the base station or at least one condition. At least one condition includes a power headroom, a coding rate of high priority data/UCI, or a percentage of resource in high UL channel that is taken by low priority UL transmissions

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may multiplex one or more demodulation reference signals (DMRSs) with data or uplink control information in each symbol of one or more physical uplink communications. The UE may transmit the symbols of the one or more physical uplink communications. The physical uplink communications may include physical uplink repetitions. Numerous other aspects are provided.

Abstract: Aspects of the present disclosure provide techniques for communicating channel state information (CSI) reports. In some aspects, downlink resources can be monitored for reception of downlink signaling, a CSI report can be generated based on the reception of the downlink signaling, where the CSI report indicates CSI for each of multiple sub-bands of the downlink resources, and the CSI report can be transmitted with hybrid automatic repeat request (HARQ) acknowledgement or negative acknowledgement (ACK/NACK) feedback associated with the downlink signaling to facilitate retransmission with improved block error rate (BLER). In some aspects, a base station receiving the CSI report, or otherwise based on uplink signals, can determine transmission parameters for retransmission to facilitate the improved BLER.

Abstract: Aspects of the present disclosure provide apparatus, methods, processing systems, and computer readable mediums that allow a switch between coherent physical uplink control channel (PUCCH) transmissions (e.g., that include demodulated reference signals (DMRS)) and non-coherent PUCCH transmissions (e.g., without DMRS). An example method by a user equipment (UE) generally includes receiving, from a network entity, a configuration of a set of PUCCH resources with different PUCCH formats, receiving signaling, from the network entity, indicating one of the PUCCH resources for a PUCCH transmission and whether the PUCCH transmission is to be sent as a coherent transmission or non-coherent transmission, and sending the coherent or non-coherent PUCCH transmission in accordance with the indication.
