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 configuration message that indicates a radio resource allocation and a transmission scheme for one or more first configured grant-small data transfer (CG-SDT) occasions and one or more second CG-SDT occasions. The one or more second CG-SDT occasions are at least partially nested, in time, frequency, or a combination thereof, within the one or more first CG-SDT occasions. The UE may therefore transmit, to the base station, an uplink communication within the one or more first CG-SDT occasions or the one or more second CG-SDT occasions, using the radio resource allocation and the transmission scheme. Numerous other aspects are provided.

Abstract: A base station may configure CSI-IM resources in a downlink BWP in a full-duplex slot. A UE may measure interference components in the CSI-IM resources and generate/transmit a CLI report comprising the measurement of the interference components to the base station. The measurement of interference components may include an RSSI measurement of intra-cell CLI from an interfering uplink signal transmitted from an aggressor UE or a self-interference from an uplink channel of the UE. The uplink signal may be an SRS, and the CLI report may include the RSSI, an RSRP, and/or an RSRQ of the interference in the CSI-IM resources in the uplink channel. The CSI-IM resources and the CLI report may have various configurations.

Abstract: A wireless device can flexibly switch between different frequency-division duplexing (FDD) modes including one or more half-duplex (HD) FDD modes and a full-duplex (FD) FDD mode in wireless communication. The wireless device can intelligently switch between the FDD modes to meeting different requirements of power consumption, traffic latency, and/or coverage enhancement.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may receive a timing advance (TA) command indicating partial TA compensation, start a TA timer for partial TA compensation for full duplex based at least in part on receiving the TA command, and perform a synchronization procedure based at least in part on expiration of the TA timer for partial TA compensation for full duplex. Numerous other aspects are provided.

Abstract: Apparatus, methods, and computer-readable media for managing HARQ-ACK processes in wireless user equipment (UEs) allow selective compression of HARQ-ACK information within HARQ-ACK codebooks. A wireless base station may transmit control information including scheduling information for K downlink transport blocks for a UE, and may signal bundling rules for selectively compressing an original HARQ-ACK codebook of size K into a constrained HARQ-ACK codebook of size N

Abstract: Some techniques and apparatuses described herein permit a user equipment (UE) to transition among different power configurations, which include different values for different power parameters, that impact an amount of power consumed by the UE. In some aspects, these transitions may be signaled by a base station based at least in part on traffic volume for the UE, which may assist with improving throughput and/or extending battery life of the UE. Furthermore, these transitions may be signaled dynamically, such as in downlink control information (DCI) and/or a medium access control (MAC) control element (CE) MAC-CE, which may conserve battery power and/or network resources as compared to reconfiguring the UE using an RRC message, and which may allow the UE to be reconfigured quickly as conditions associated with the UE change.

Abstract: Certain aspects of the present disclosure provide techniques for scheduling and bandwidth part (BWP) adaptation for extended reality (XR). A method that may be performed by a user equipment (UE) includes obtaining an indication to change at least one of a minimum control-channel-to-data-channel delay or a bandwidth for receiving a first transmission on a BWP; changing the at least one of the minimum control-channel-to-data-channel delay to a new minimum control-channel-to-data-channel delay or the bandwidth on the BWP to a new bandwidth; and receiving the first transmission on the BWP using the at least one of the new minimum control-channel-to-data-channel delay or the new bandwidth of the BWP.

Abstract: A UE receives DCI in a PDCCH, the DCI triggers reception of AP CSI-RS, and the PDCCH has a first numerology and the AP CSI-RS has a second numerology. The UE determines, when a CORESET is configured on an active BWP of a serving cell for receiving the AP CSI-RS and when the first numerology is the same as the second numerology, a default AP CSI-RS beam for receiving the AP CSI-RS based on a beam used for receiving the CORESET with a lowest ID in a latest monitored slot of the active BWP of the serving cell. The UE determines, otherwise when the first numerology is the same as the second numerology, the default AP CSI-RS beam for receiving the AP CSI-RS based on a QCL assumption of a PDSCH TCI state with a lowest ID on the active BWP of the serving cell for receiving the AP CSI-RS.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may receive downlink control information (DCI) that schedules a first communication on a first bandwidth part and a second communication on a second bandwidth part; determine one or more parameters for the first bandwidth part and the second bandwidth part based at least in part on the DCI and in accordance with a bandwidth part configuration for a virtual bandwidth part; and perform the first communication and the second communication based at least in part on the one or more parameters. Numerous other aspects are provided.

Abstract: Certain aspects of the present disclosure relate to wireless communications, and more particularly, to techniques for a UE to measure sounding reference signal (SRS) transmission from another UE. The measurements results may be used, for example, by a serving cell for interference mitigation purposes. For example, the disclosed techniques may include a first UE receiving a configuration for measuring SRS transmitted by a second UE; determining a first bandwidth part (BWP) associated with the configuration; determining a frequency reference point for the SRS to be measured; determining SRS measurement resources, based on one or more parameters of the configuration and the frequency reference point; and measuring SRS transmitted by the second UE on the determined SRS measurement resources.
