Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a sounding reference signal (SRS) configuration indicating a first SRS resource set that includes NSRS,0_21 SRS resources and a second SRS resource set that includes NSRS,0_22 SRS resources, the first SRS resource set and the second SRS resource set being configured for uplink transmissions scheduled by a second downlink control information (DCI) format. The UE may transmit an uplink transmission scheduled using the second DCI format, the uplink transmission being transmitted based at least in part on the SRS configuration. Numerous other aspects are described.

Abstract: Certain aspects of the present disclosure provide techniques for unlicensed channel occupancy time sharing based on received signal strength. A method that may be performed by a first user equipment (UE) includes receiving a first transmission from a second UE, the first transmission indicating the second UE has acquired a frequency band for a channel occupancy time (COT). The method may also include transmitting a signal within the frequency band during the COT in response to a signal strength of the first transmission as received by the first UE being greater than at least one threshold.

Abstract: Methods, systems, and devices for wireless communications are described. A first user equipment (UE) may determine that that the first UE is scheduled to transmit a control signal and a synchronization signal associated with a synchronization signal block. The first UE may transmit, to a second UE during a first set of symbols within a time period, the control signal associated with a sidelink communication. In some examples, the first UE may transmit, to the second UE during a symbol subsequent to the first set of symbols, the synchronization signal associated with the synchronization signal block, and may communicate with the second UE according to the transmitted control signal and the transmitted synchronization signal.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may receive a cancellation indication associated with an uplink transmission on a shared radio frequency spectrum band, the shared radio frequency spectrum band having a listen-before-talk channel access mechanism to access the shared radio frequency spectrum band; determine, based at least in part on the reception of the cancellation indication associated with the uplink transmission on the shared radio frequency spectrum band, whether the uplink transmission is to be cancelled or transmitted at a reduced transmit power; and when the uplink transmission is to be transmitted at the reduced transmit power, transmitting the uplink transmission at the reduced transmit power.

Abstract: Aspects relate to transmission of physical uplink control channel (PUCCH) information. A user equipment may receive a first physical downlink control channel (PDCCH) candidate carried by a control resource set that also carries a second PDCCH candidate, where these PDCCH candidates are associated with different aggregation levels. The user equipment may identify a PUCCH resource for transmission of information (e.g., an ACK or a NACK) that is associated with a physical downlink shared channel (PDSCH) transmission scheduled by the first PDCCH candidate. For example, the user equipment may identify the PUCCH resource based on a control channel element (CCE) index that corresponds to a starting CCE of the first PDCCH candidate and the second PDCCH candidate.

Abstract: Certain aspects of the present disclosure provide techniques for indicating actual transport block size (TBS) on shaping encoding. For example, in shaping encoding, instead of using a compensated rate code (e.g., by padding or truncating) for a fixed number of output bits that is often different from the TBS scheduled, the present disclosure supports using multiple actual TBS for a given nominal TBS to improve efficiency of the shaping encoder. A transmitter (e.g., a network entity or use equipment (UE)) may encode a payload size of bits with a shaping encoder to obtain a transport block (TB), which has an actual TBS. The actual TBS is selected from a set of TBSs based on a nominal TBS. The transmitter then transmits to a receiver, an indication of the actual TBS. The indication enables the receiver to decode the corresponding encoded bits. The transmitter then transmits the TB to the receiver.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may transmit, in a first slot within a channel occupancy time (COT), a first communication; determine whether one or more transmission criteria are satisfied for transmission of a second communication in a second slot within the COT; and selectively transmit the second communication in the second slot within the COT based at least in part on a result of determining whether the one or more transmission criteria are satisfied. Numerous other aspects are provided.
