The network entity may further transmit an indication including the beam sweep pattern to a user equipment (UE). In another aspect, a UE may receive a beam sweep pattern for at least one of a SPS based downlink periodic transmission, an uplink control transmission for the SPS based downlink periodic transmission, or a CG based uplink periodic transmission from a network entity.

Abstract: A method for wireless communication performed by a user equipment (UE) includes receiving, from a network node, a message indicating a set of multi-slot monitoring configurations supported by a base station based on a minimum monitoring occasion periodicity associated with a search space being greater than or equal to one slot. The method also includes transmitting, to the network node, a selection message indicating selection of a single multi-slot monitoring configuration from the set of multi-slot monitoring configurations. The method still further includes monitoring the search space for a physical downlink control channel (PDCCH) transmission in a plurality of non-consecutive monitoring occasion groups, each monitoring occasion group comprising a plurality of non-consecutive monitoring occasions based on the single multi-slot monitoring configuration.

Abstract: A base station may schedule a plurality of synchronization signal blocks (SSBs) in an extended discovery burst (DRS) transmission window including a plurality of candidate SSBs including at least two candidate SSBs with a same SSB beam index, and transmit the plurality of SSBs based on the scheduling of the plurality of SSBs in the extended DRS transmission window. A UE may monitor for a plurality of SSBs in the extended DRS transmission window including the plurality of candidate SSBs including at least two candidate SSBs with the same SSB beam index, and perform measurements based on SSBs of the plurality of SSBs received from the base station. The base station may transmit a signal indicating one or more scheduling parameters of the plurality of SSBs, and the UE may determine SSB index of each candidate SSB of the plurality of candidate SSBs.

Abstract: Example implementations include a method, apparatus and computer-readable medium of wireless communication. A user equipment (UE) may receive a configuration indicating whether a beam switching gap is expected at a first symbol position within a subframe of a physical channel for the UE, the first symbol position having a first cyclic prefix length that is longer than a second cyclic prefix length of a second symbol position within the subframe of the physical channel for the UE. The UE may determine whether a transmission includes a missing symbol for the beam switching gap based on the configuration and the symbol position of a symbol where a beam switch is scheduled.

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, an indication that demodulation reference signal (DMRS) bundling is to be used for channel estimation by the base station for one or more physical uplink control channel (PUCCH) repetitions, where the indication is a semi-static configuration or a dynamic indication. The UE may transmit, to the base station, the one or more PUCCH repetitions by maintaining a phase continuity among DMRSs of the one or more PUCCH repetitions based at least in part on receiving the indication that DMRS bundling is to be used. Numerous other aspects are described.

Abstract: Control information such as downlink control information (DCI) may be used to indicate whether the DCI is for semi-persistent scheduling (SPS) cancellation. For example, the base station may transmit, to a user equipment (UE), first DCI to trigger an SPS configuration of a plurality of SPS occasions. The base station may further determine to cancel one or more SPS occasions of the plurality of SPS occasions, and transmit second DCI to trigger an SPS cancellation that cancels the one or more SPS occasions, the second DCI including at least a redundancy version field including one or more redundancy version values to indicate the SPS cancellation.

Abstract: Wireless communications systems and methods related to multiple starting points for new radio sidelink transmission over unlicensed band are provided. In some aspects, a UE may perform a channel access procedure to access a first physical sidelink shared channel (PSSCH) transmission resource of an unlicensed new radio spectrum. In some aspects, the first PSSCH transmission resource may be reserved by a control message and may include a plurality of transmission starting points. Further, the first UE may transmit first data to a second UE via the first PSSCH transmission resource starting at a later transmission starting point than one or more prior transmission starting points of the plurality of transmission starting points when the performing the channel access procedure fails at each of the one or more prior transmission starting points.
