Abstract: This disclosure provides systems, devices, apparatus, and methods, including computer programs encoded on storage media, for PUCCH/PUSCH DMRS bundling. A UE may transmit, to a network entity, a first indication of a maximum DMRS bundling duration for maintaining transmit phase coherence for transmitted DMRS. The UE may receive, from the network entity based on the first indication of the maximum DMRS bundling duration, a second indication of at least one of a DMRS bundling activation or a DMRS bundling duration. Based on the at least one of the DMRS bundling activation or the DMRS bundling duration, the UE may transmit at least one UL repetition including bundled DMRS.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a mobile station may generate capability information that indicates a capability of the mobile station to support cross-slot channel estimation based on uplink reference signals across uplink transmissions after switching between a first carrier and a second carrier, based at least in part on the mobile station being capable of supporting cross-slot channel estimation across the uplink transmissions. The mobile station may transmit the capability information. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine a number of repetitions of a message 3 (msg3) communication of a four-step random access channel (RACH) procedure that are to be transmitted to a base station. The UE may transmit, to the base station, the repetitions of the msg3 communication based at least in part on determining the number of the repetitions of the msg3 communication. Numerous other aspects are provided.

Abstract: Wireless communication devices, systems, and methods related to bundling of uplink communication signals under timing advance (TA) conditions are provided. For example, a method of wireless communication performed by a user equipment can include receiving, from a base station, a timing advance (TA), wherein the TA is scheduled to be implemented by the user equipment at a first time, the first time being after a start of a first uplink communication of a group of bundled uplink communications scheduled with phase coherence and before a start of a second uplink communication of the group of bundled uplink communications; determining whether to implement the TA at the first time or a second time, the second time being after transmission of the second uplink communication; and implementing the TA based on the determining

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may select, from a first path and a second path, a path for an uplink communication associated with at least one of a variable payload size for hybrid automatic repeat request (HARQ) feedback or channel state information (CSI) feedback, wherein the first path is on an uplink of the UE and the second path is on a sidelink of the UE; and transmit the uplink communication on the selected path. Numerous other aspects are provided.

Abstract: Certain aspects of the present disclosure provide techniques for coordinated power savings configurations for access link and sidelink(s). A wireless node may receive information from a user equipment (UE) over a sidelink. In some aspects, the wireless node forwards the information to a base station (BS) over an access link and receives, from the BS, a first power savings configuration for the access link and a second power savings configuration for the sidelink. In some aspects, the wireless node receives, from a BS, a first power savings configuration for an access link and determines a second power savings configuration for the sidelink based on the information and the first power savings configuration.

Abstract: Some aspects provide a method for wireless communication by a user equipment (UE). The method generally includes receiving signaling of a spatial preemption indication (PI), identifying, based on the spatial PI, at least one beam that the UE is preempted from using for at least one of transmitting or receiving at least one target signal, and refraining from using the identified beam for transmitting or receiving the target signal, for at least a time period.

Abstract: Certain aspects of the present disclosure provide techniques for providing channel state information associated with sidelink air interfaces. A method that may be performed by a first wireless node (e.g., a user equipment) includes receiving, from a base station, a reference signal (RS) configuration indicating one or more sidelink resource sets and transmitting, to one or more second wireless nodes, one or more sidelink reference signals based at least in part on the RS configuration. The method also includes receiving one or more feedback reports from the one or more second wireless nodes, wherein each of the feedback reports includes an ordered sequence of at least one parameter associated with a sidelink channel quality of the sidelink reference signals. The method further includes forwarding the one or more feedback reports to the base station.
