Abstract: This disclosure relates to methods, devices, and systems for wireless communications, and more particularly to aggregating physical uplink shared channel (PUSCH) resource units relating to a random access message. A user equipment (UE) may identify a random access message of a random access procedure. The random access message may include a random access preamble and a random access payload. The UE may aggregate multiple PUSCH resource units of a set of PUSCH resource units associated with one or more PUSCH occasions (POs) based on one or more of a payload size of the random access payload or a modulation and coding scheme associated with the random access payload. As a result, the UE may transmit the random access payload of the random access message on a PUSCH using time and frequency resources of the aggregated multiple PUSCH resource units over the one or more POs.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station may configure an uplink transmission pattern related to an uplink transmission resource on multiple component carriers. The base station may transmit, to a user equipment (UE), information related to activating the uplink transmission pattern in a single scheduling message. Accordingly, the UE may transmit information on the multiple component carriers in one or more uplink symbols based at least in part on the uplink transmission pattern. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit a first indication of one or more carriers, including a first carrier, that are affected by an operation associated with one or more other carriers. The UE may receive a second indication to switch a transmitting radio frequency (RF) chain of the UE from a second carrier to the first carrier at a first time. The UE may perform the operation at a second time that at least partially overlaps with the first time. The UE may suspend the switch of the transmitting RF chain to the first carrier based on performing the operation. The UE may configure the transmitting RF chain to be tuned to the first carrier or the second carrier at a third time that occurs after the second time. Numerous other aspects are described.

Abstract: Certain aspects of the present disclosure provide techniques for signaling a scheduling offset for non-terrestrial networks (NTNs). In one aspect, a method for wireless communications by a user equipment (UE) includes receiving first signaling indicating a first part of a scheduling offset associated with a common timing advance (TA); receiving second signaling indicating a second part of the scheduling offset; and transmitting an uplink transmission based on the first and second parts of the scheduling offset.

Abstract: A UE transmits UE capability information to a first base station on a first carrier. The UE capability information is associated with a CA switching period for a second carrier or is indicating a set of bands associated with CA bands of at least the second carrier. The first and second carriers belong to different TAGs. The UE switches from communicating on the first carrier associated with a first TA of a first TAG to communicating on the second carrier associated with a second TA of a second TAG. The first TAG is different from the second TAG. The first TA is greater than the second TA. The second carrier is associated with the CA switching period or the set of bands associated with the CA bands. The UE communicates with a second base station on the second carrier based on the transmitted UE capability information.
