Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may jointly measure channel state information (CSI) resources corresponding to a first reporting occasion of a first CSI report in setting and a second reporting occasion of a second CSI report setting if the first reporting occasion is linked to the second reporting occasion based at least in part on a slot position of the first reporting occasion relative to a slot position of the second reporting occasion. The first CSI report setting may be associated with the second CSI report setting for reporting CSI associated with non-coherent joint transmission. The UE may transmit a first report for the first CSI report setting at the first reporting occasion and a second report for the second CSI report setting at the second reporting occasion. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communication are described that provide for reduced timing between certain downlink communications and responsive uplink communications relative to certain legacy systems (e.g., legacy LTE systems). A user equipment (UE) or base station may be capable of operating using two or more timing configurations that each include an associated time period between receipt of a downlink communication (e.g., a grant of uplink resources or shared channel data) and a responsive uplink communication (e.g., an uplink transmission using the granted uplink resources or feedback of successful reception of the shared channel data). In cases where a UE or base station are capable of two or more timing configurations, a timing configuration for a transmission may be determined and the responsive uplink communication transmitted according to the determined timing configuration.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station, a channel occupancy time (COT) duration indication that indicates a first COT duration associated with a first channel occupancy initiated by the base station. The UE may initiate, during a time duration that is outside of the first COT duration and based at least in part on performing a listen-before-talk procedure, a second channel occupancy having a second COT duration. Numerous other aspects are described.

Abstract: Wireless communications systems and methods related to channel access in a shared radio frequency band in an unlicensed spectrum or a shared spectrum are provided. A wireless communication device determines a channel access procedure based on whether one or more channel access conditions are satisfied for accessing an unlicensed frequency band. The one or more channel access conditions are associated with at least one of sensing across multiple channel occupancy times (COTs), a transmission beam characteristic, a transmit power, a transmission duty cycle, or a beam dwell time. The wireless communication device transmits, based on the channel access procedure, a communication signal in the unlicensed frequency band.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may perform a channel access procedure associated with a transmission of a sidelink communication that is to be associated with resources that are associated with a first configured grant configuration, wherein the channel access procedure is unsuccessful, wherein the sidelink communication is associated with a hybrid automatic repeat request (HARQ) process identifier, and wherein a state associated with the HARQ process identifier is changed to pending based on the channel access procedure being unsuccessful. The UE may transmit, based on successfully performing another channel access procedure, a retransmission of the sidelink communication using resources associated with the first configured grant configuration or a second configured grant configuration based on the state associated with the HARQ process identifier being changed to pending. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may receive, from a base station (BS), a channel state information reference signal (CSI-RS) communication; and transmit, to the BS, a physical uplink control channel communication including feedback information that is a response to the CSI-RS communication and including an interference measurement. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. A communication device, otherwise known as a user equipment (UE) may receive, in a first control resource set (CORESET), a first downlink control information (DCI) message scheduling a first uplink shared channel, the first CORESET corresponding to a first CORESET pool index. The UE may receive, in a second CORESET, a second DCI message scheduling a second uplink shared channel, the second COREST corresponding to a second CORESET pool index different from the first CORESET pool index, where the second DCI message may be received before transmission of the first uplink shared channel. The UE may transmit both the first uplink shared channel and the second uplink shared channel based on the first uplink shared channel and the second uplink shared channel corresponding to a same hybrid automatic repeat request (HARM) process.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine a transmission of a channel status information (CSI) report based at least in part on receiving a CSI request via PDCCH repetitions, based at least in part on transmitting the CSI report via PUCCH repetitions, or based at least in part on transmitting the CSI report via PUSCH repetitions. The UE may determine, based at least in part on the determined transmission of the CSI report, CSI processing criteria including one or more of a CSI processing timeline, a CSI processing unit occupation duration, a resource and port occupation duration, or a CSI reference resource slot. The UE may selectively transmit the CSI report based at least in part on the determined CSI processing criteria. Numerous other aspects are described.
