Abstract: Methods, systems, and devices for wireless communication at a user equipment (UE) are described. A UE may receive control signaling configuring at least a first UE operation mode and a second UE operation mode. The UE may transmit one or more uplink messages to a base station in the unlicensed radio frequency spectrum band using a first set of parameters according to the first UE operation mode. In some examples, the UE may receive a control message comprising an indication that the UE is to switch from communicating according to the first configured UE operation mode to communicating according to the second configured UE operation mode. The UE may then transmit, in response to the received indication, one or more uplink messages to the base station in the unlicensed radio frequency spectrum band using a second set of parameters according to the second UE operation mode.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive downlink control information (DCI) that includes an indication to transmit a physical uplink shared channel (PUSCH) communication, associated with the DCI, using a single-frequency network (SFN) communication scheme in which each layer of the PUSCH communication is transmitted simultaneously from multiple antenna modules of the UE. The UE may transmit the PUSCH communication in accordance with the DCI. Numerous other aspects are described.

Abstract: This disclosure provides systems, methods and apparatus for wireless communications. In one aspect, a device, such as a user equipment (UE) may receive a configuration including one or more channel state information (CSI) measurement resources associated with a set of CSI hypotheses. The set of CSI hypotheses may correspond to a set of transmission configuration indicator (TCI) states, or a CSI interference measurement (CSIIM) resource, or both. The UE may select a first CSI measurement resource of the one or more CSI measurement resources for a channel measurement based on a CSI hypothesis of the set of CSI hypotheses. The UE also may select the CSIIM resource or a second CSI measurement resource for an interference measurement based on the CSI hypothesis of the set of CSI hypotheses. The UE may, as a result, transmit a report based on the channel measurement or the interference measurement, or both.

Abstract: A first UE may be configured to receive a common message associated with the first UE and at least one second UE. The first UE may be configured to obtain a common message configuration having at least one of a first indicator for a first data portion of the common message associated with the first UE or at least one second indicator for at least one second data portion of the common message associated with the at least one second UE. The common message configuration may be obtained from at least one of a header of the common message or DCI scheduling the common message.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine a power headroom (PHR) value for a component carrier (CC) based at least in part on a physical uplink shared channel (PUSCH) transmission in the CC, wherein the PUSCH transmission includes a first repetition associated with a first set of power control parameters and a second repetition associated with a second set of power control parameters, and wherein the PHR value is determined based at least in part on one or more of the first repetition or the second repetition. The UE may transmit information identifying the PHR value for the CC. Numerous other aspects are provided.

Abstract: This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer storage media, for handling hybrid automatic repeat request (HARQ) processes with discontinuous reception (DRX) operations. A user equipment (UE) may use timers to maintain an ON duration in DRX. The UE may receive, via downlink control information (DCI), an indication of a feedback transmission opportunity (TxOP) for a HARQ process. The UE may activate a timer at the end of the TxOP regardless of whether the UE transmits feedback in the TxOP to ensure that the UE remains active. In some implementations, a base station may provide the UE with multiple opportunities to transmit a feedback message. The UE may reactivate a timer after each feedback TxOP for the same HARQ process or may activate the timer after the first feedback TxOP and may refrain from activating the timer after subsequent feedback TxOPs for the HARQ process.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a mobile station may receive, from a base station, information indicating resource locations in which one or more synchronization signal blocks (SSBs), of a set of SSBs, are to be transmitted. The mobile station may selectively monitor a plurality of sets of resource element groups (REGs) of physical downlink control channel (PDCCH) repetitions based at least in part on whether at least one SSB, of the one or more SSBs, is to collide with one or more of the plurality of sets of REGs. Numerous other aspects are described.

Abstract: This disclosure provides systems, methods, and devices for wireless communication that support mechanisms for sidelink beamforming alignment over a set of resources based on a deterministic sequence in a wireless communication system. In aspects, an sidelink initiator user equipment (UE) may initiate a beamforming alignment procedure with a responder UE over a the sidelink. The initiator UE may define a set of subchannels specified by a deterministic sequence. The set of subchannels may be subchannels over which the initiator UE may perform reception beam sweeping. The deterministic sequence may be anchored to a direct frame number (DFN) of the sidelink frame without initial sensing, and may be determined via a sequence index, as a function of sidelink UE identification ID(s), or a combination thereof. In this manner, the number of bits for indicating the deterministic sequence to the responder UE may be reasonable, manageable, and/or moderate.

In some aspects, a UE may receive, from a BS, a positioning reference signal (PRS). The UE may further transmit, in response to and at a predetermined time after the receiving the PRS, a sounding reference signal (SRS) to the BS. Further, the UE may receive, from the BS, a delay measurement corresponding to the PRS.
