  • Publication number: 20230284188
    Abstract: Aspects of the present disclosure provide techniques for wireless communication. A method by a user equipment (UE) includes receiving scheduling information from a network entity. The scheduling information schedules transmission of a first uplink (UL) channel repetition of a plurality of UL channel repetitions in a first full duplex (FD) slot of a plurality of slots. Additionally, the first UL channel repetition is associated with one or more time domain resource allocations (TDRAs) and one or more frequency domain resource allocations (FDRAs). Additionally, based on the one or more FDRAs associated with the first UL channel repetition, a portion of the first UL channel repetition is scheduled to occur in a downlink subband of the first FD slot. The method also includes taking one or more actions to transmit the first UL channel repetition based on the scheduling information.

  • Patent number: 11751234
    Abstract: Methods, systems, and devices for wireless communications are described. A first base station may communicate during asynchronous slots in accordance with a set of communication parameters determined from a handshake procedure performed with a second base station. For example, based on a change to a slot type of a slot to an asynchronous slot, the first base station and the second base station may perform the handshake procedure to determine the set of communication parameters and may communicate one or more messages during the slot in accordance with the set of communication parameters. Additionally, or alternatively, a user equipment (UE) may transmit a sounding reference signal (SRS) associated with a transmission configuration indicator (TCI) state based on a slot type of a first slot in which the UE transmits the SRS and a reference signal received in a second slot having the slot type.

    Abstract: Certain aspects of the present disclosure provide techniques for enhancing sidelink resource utilization for a user equipment (UE) that supports full duplex (FD) communications. For example, an FD UE may receive incoming sidelink communication over a first set of resources and, in FD mode, simultaneously transmit another sidelink communication over the same first set of resources. According to aspects of the present disclosure, the potential interference between the two sidelink communications will be mitigated or reduced, such as by having the FD UE negotiate with other sidelink UEs over transmission power levels and related aspects, such as beam coordination and/or resource subset designation, or the like.

  • Patent number: 11723028
    Abstract: A user equipment (UE) communicates with a base station operating in a sub-band frequency division duplexing (FDD) mode. The UE receives a downlink transmission in a usable bandwidth (BW) of an active downlink bandwidth part (BWP) in a sub-band full duplex (SBFD) slot, where the usable BW does not include frequency resources used for guard band and uplink transmission. The UE monitors for one or more control resource set (CORESET) configured by the base station within the active downlink BWP during monitoring occasions.

  • Publication number: 20230247465
    Abstract: A victim user equipment (UE) may experience cross-link interference (CLI) from a physical uplink shared channel (PUSCH) transmission from an aggressor UE or self-interference (SI) from a PUSCH transmission from a transmitter of the victim UE. The present disclosure provides for configuration of measurement resources and a CLI report for mitigation of CLI. A base station may transmit a configuration of the measurement resources including channel state information interference measurement (CSI-IM) resources and a configuration of a CLI report. The CSI-IM resources match PUSCH symbols or demodulation reference signal (DMRS) symbols of an aggressor UE. The victim UE measures a CLI or a SI on the CSI-IM resources. The victim UE reports the CLI or the SI to the base station according to the configuration of the CLI report. The base station may schedule transmissions to mitigate the CLI or the SI.

  • Patent number: 11716699
    Abstract: A user equipment (UE), such as a full-duplex UE, may receive a downlink transmission from a first transmit-receive point (TRP) in a full-duplex multi-TRP configuration. The UE may perform an uplink transmission to a second TRP in the full-duplex multi-TRP configuration based at least in part on a timing advance adjustment associated with the uplink transmission. The UE may apply the timing advance adjustment based at least in part on an indication received from a base station. The indication may be to set a timing advance offset to a value that satisfies a threshold value based at least in part on the downlink transmission and the uplink transmission being associated with two different TRPs. The downlink transmission and the uplink transmission may not be separated by a guard symbol when the downlink transmission and the uplink transmission are associated with the two different TRPs, which may improve a resource utilization.
