Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a network entity, a configuration of at least one sounding reference signal (SRS) resource, wherein the configuration indicates a pseudo-random sequence for muting an SRS associated with the at least one SRS resource. The UE may transmit the SRS using the at least one SRS resource based at least in part on the pseudo-random sequence. Numerous other aspects are described.

Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. A user equipment (UE) may receive, via a control channel in a primary cell, one or more downlink control information (DCI) messages that include a secondary cell (SCell) dormancy indication and a request for hybrid automatic repeat request (HARQ) feedback. The DCI messages may have a format associated with downlink scheduling, and fields used to carry the SCell dormancy indication and the request for HARQ feedback may have a configuration that depends on whether the DCI messages are used to schedule a downlink data transmission. Furthermore, in some aspects, a DCI message may include a field that has a value to indicate whether the DCI message does or does not schedule a downlink data transmission, to enable the UE to correctly receive and decode the SCell dormancy indication and the request for HARQ feedback.

Abstract: Wireless communication systems and methods related to configuration for user equipment (UE)-initiated channel occupancy time (COT) in a frame-based equipment (FBE) mode are provided. A user equipment (UE) receives, from a base station (BS), a configuration for the UE to initiate a COT in an FBE mode. The configuration indicates a first FBE frame period. The UE initiates the COT in a first FBE frame having the first FBE frame period. The UE transmits, to the BS during the COT, an uplink communication signal.

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: 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: Certain aspects of the present disclosure provide techniques for communicating using sidelink resources allocated in an unlicensed spectrum. A method that may be performed by a first UE includes establishing a connection with a second UE for sidelink communication in an unlicensed spectrum and communicating with the second UE via the connection using one or more sidelink sub-channels in the unlicensed spectrum according to a mapping between sidelink sub-channels and resource block (RB) sets of the unlicensed spectrum, wherein the unlicensed spectrum comprises a plurality of RB sets and one or more guard bands disposed between RB sets in the plurality RB sets.

Abstract: Aspects relate to techniques for exchanging resource pool (RP) configurations between wireless communication devices. A transmitting wireless communication device can transmit a remaining minimum system information (RMSI) message including a RP configuration of the transmitting wireless communication device to at least one receiving wireless communication device. The RMSI message is transmitted within a minimum resource block set that is common to both the transmitting wireless communication device and the at least one receiving wireless communication device. The transmitting wireless communication device may then communicate with the at least one receiving wireless communication device on a sidelink based on the RP configuration.
