Abstract: A random access procedure between a user equipment (UE) and a base station may include repetition of a random access message 3 to improve reception and provide for selection of a refined beam. The UE may receive, using a first receive beam, a random access message 2 transmitted by a base station using a first transmit beam. The random access message 2 indicates to the UE to transmit a plurality of repetitions of a random access message 3. The UE may transmit the plurality of repetitions based on the random access message 2. The UE may receive a random access message 4 transmitted by the base station using a second transmit beam that is a sub-beam of the first transmit beam based on transmitting the plurality of repetitions. The base station may select the second transmit beam based on at least one of the plurality of repetitions.

Abstract: Certain aspects of the present disclosure relate to wireless communications, and more particularly, to techniques for determining when to apply beam updates. A method that may be performed by a user equipment (UE) includes receiving signaling indicating a beam update, determining an application time of the beam update occurs between a downlink control information (DCI) scheduling a transmission and the scheduled transmission, and deciding whether to apply the beam update to the scheduled transmission.

Abstract: A configuration to suspend UE communication with a base station based on instructions from the base station. The apparatus receives, from a base station, a silencing instruction for at least one of uplink communication or downlink communication. The apparatus determines a first duration associated with the at least one of uplink communication or downlink communication based on the silencing instruction. The apparatus refrains from all of the at least one of uplink communication or downlink communication with the base station for the first duration in response to receiving the silencing instruction.

Abstract: Aspects relate to obtaining, at a first scheduled entity, a first priority ranking of first uplink (UL) data scheduled for transmission to a scheduling entity and a first data scheduled for transmission to a second scheduled data, as well as a second priority ranking of second data scheduled for transmission to a third and fourth scheduled entity, respectively. The scheduling uses at least a portion of a sidelink resource reserved for sidelink communication for the transmissions. The scheduling of the transmissions using at least the portion of the sidelink resource are based on the first priority ranking and the second priority ranking. Various transmission cancellation and reception preemptions are transmitted from transmitting scheduled entities to other transmitting or receiving scheduled entities, respectively. Such cancellations and preemptions are based on the priority rankings, prediction of data transmission collisions and prediction of interference at receiving entities.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine an operating mode associated with synchronization signal block (SSB) transmission in a band, wherein the operating mode is one of a licensed operating mode or an unlicensed operating mode; and receive one or more SSBs based at least in part on the operating mode. Numerous other aspects are described.

Abstract: A user equipment (UE) may receive a downlink control information (DCI) including an antenna port field and a transmission configuration indication (TCI) field for scheduling a physical downlink shared channel (PDSCH). The TCI field may indicate that two or more reference signals apply to two or more demodulation reference signal (DMRS) ports across all resource blocks and symbols for the PDSCH for at least one transmission layer of the PDSCH. The antenna port field may indicate a plurality of indicated DMRS ports. The UE may map two or more DMRS ports of the indicated DMRS ports to at least one transmission layer of the PDSCH. The UE may receive the at least one transmission layer of the PDSCH as a single-frequency-network (SFN) transmission based on the two or more reference signals and the two or more DMRS ports.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit beam information, associated with the UE, during a random access channel (RACH) procedure and while in an inactive mode or in an idle mode. The UE may remain in the inactive mode or in the idle mode after transmitting the beam information. Numerous other aspects are provided.

Abstract: Certain aspects of the present disclosure provide techniques for measurements on a first frequency band applicable to procedures on a second frequency band. A technique that may be performed by a user equipment (UE) may include sending a base station (BS) an indication of the first frequency band, which may be a preferred measurement frequency band. The UE may then measure one or more reference signals (RSs) on the preferred measurement frequency band. The UE may then apply the measurements of the one or more RSs on the preferred measurement frequency band for one or more procedures on the second frequency band.

Abstract: Certain aspects of the subject matter described in this disclosure can be implemented in a method for wireless communication by a user equipment (UE). The method generally includes receiving, from a network entity, a configuration for a first bandwidth part (BWP) configured with frequency hopping, determining a frequency location of the first BWP during each of a plurality of frequency hops for the frequency hopping based on a reference frequency location, and communicating with the network entity via the first BWP and in accordance with the configuration.

Abstract: A user equipment (UE) determines a beam failure of a default uplink beam for the UE. The UE transmits an uplink beam failure report in response to determining the beam failure of the default uplink beam, the uplink beam failure report indicating that a reported beam is the default uplink beam for the UE. A base station receives an uplink beam failure report from the UE and determines that a reported beam is a default uplink beam for the UE.
