Abstract: Disclosed are systems and techniques for performing sidelink communications. For instance, a first client device can determine a first transmit power parameter for transmitting sidelink communications. The first transmit power parameter can either be received from a base station associated with the first client device or it can be a default parameter based on the first client device not being associated with a base station. The first client device can transmit, to a second client device, a first sidelink transmission having a first power level corresponding to the first transmit power parameter. The first client device can receive, from the second client device, a first sidelink reception having a second power level corresponding to a second transmit power parameter.

Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for managing transmit power control. In one aspect, a wireless device may receive a message including a path loss value and may transmit a signal to a UL Rx point using an uplink transmit power associated with the received path loss value. In another aspect, a wireless device may receive a reference signal, and a message including an offset value, and may transmit a signal to a UL Rx point using an uplink transmit power including a downlink path loss value associated with the reference signal minus the offset value. In another aspect, a base station may obtain a power measurement of a signal from a wireless device and may send to the wireless device a path loss value associated with the received power measurement, or an offset value associated with the received power measurement.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) and base station may communicate in on a wireless channel of an unlicensed radio frequency spectrum band. The base station may transmit synchronization signal blocks (SSBs) in a discovery reference signal (DRS) slot. The base station may multiplex a channel state information (CSI) reference signal (CSI-RS). The base station may multiplex an aperiodic CSI-RS or a periodic CSI-RS with the SSBs in the DRS slot. For an aperiodic CSI-RS, the base station may separately trigger the CSI-RS measurement and CSI-RS reporting. For periodic CSI-RS, the base station may transmit an indication of whether the periodic CSI-RS is present.

Abstract: Methods, systems, and devices for wireless communications are described. The methods, systems, and devices may enable a base station to transmit a measurement configuration for measuring interference (e.g., cross link interference (CLI)). The measurement configuration may include a measurement direction configuration for measuring the interference. Additionally or alternatively, the UE may select a measurement direction configuration for measuring interference based on the measurement configuration. The UE may measure interference based on the measurement configuration. The UE may transmit a measurement report to the base station. The measurement report may include an indication of the selected measurement direction configuration.

Abstract: This disclosure provides systems, methods, apparatuses, and computer-readable media for multiplexing channel state information (CSI) reports in scenarios involving multiple transmit-receive points (TRPs). In one aspect, a user equipment (UE) may receive at least one configuration that identifies a resource for multiplexing CSI reports that have a potential to collide in a slot. The UE may receive the at least one configuration from either, or both, of a first TRP or a second TRP. The UE may transmit at least one of a first set of CSI reports to the first TRP or a second set of CSI reports to the second TRP, multiplexed in the resource, according to the at least one 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, configuration information including multiple transmission configuration indication (TCI) states associated with a control resource set (CORESET). The UE may receive, from the base station, a physical downlink control channel (PDCCH) in a region associated with the CORESET, wherein the PDCCH includes at least one control channel element (CCE). The UE may perform blind decoding for multiple configured PDCCH candidates based at least in part on a resource element group (REG) bundle included in the at least one CCE, wherein the multiple configured PDCCH candidates are associated with one or more of the multiple TC states associated with the CORESET. Accordingly, the UE may identify the PDCCH transmitted by the base station based at least in part on the blind decoding.

Abstract: Enhancement for bandwidth part (BWP) is disclosed. A base station configures a plurality of BWPs, and activate multiple BWPs for downlink and multiple BWPs for uplink from the plurality of the configured BWPs at a given time. Downlink control information (DCI) that includes BWP activation information can be transmitted on a physical downlink control channel (PDCCH) to a user equipment (UE). The BWP activation information includes a link direction, a schedule of the one or more multiple BWPs for downlink and multiple BWPs for uplink, numerologies, reserved sub-band information, tracking reference signal configuration, or any combination thereof. Correspondingly, a UE receives DCI on a PDCCH that includes BWP activation information, and determines activation of multiple BWPs for downlink and multiple BWPs for uplink at a given time based on the received DCI and its capabilities. Associated enhancement for PDCCH and PDSCH scheduling and LBT procedures are also disclosed.
