Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may initiate a first service, having a first priority during a time interval, associated with a first subscriber identification module (SIM), and a second service, having a second priority during the time interval, associated with a second SIM of the UE, the first priority having a higher priority than the second priority. The UE may identify a first type of communication associated with the second SIM. The UE may adjust, based at least in part on the first type of communication, at least one of the first priority or the second priority during the time interval. The UE may perform a communication in accordance with the adjusted at least one of the first priority or the second priority. 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 that data is buffered for transmission via a first logical channel that does not have a valid scheduling request configuration. The UE may transmit, via a scheduling request resource of a second logical channel that has a valid scheduling request configuration, a scheduling request for resources to transmit the data buffered for transmission via the first logical channel. Numerous other aspects are described.

Abstract: A UE may obtain an indication of a first subset of PRACH resources in a set of PRACH resources, the first subset of PRACH resources having a set of channel metrics that is greater than or equal to a first threshold value, select a first PRACH resource from the first subset of PRACH resources based on a first set of channel metrics of the first PRACH resource or a first RO associated with the first PRACH resource, and transmit a RACH message to a network node in the first RO. The UE may evaluate the multiple qualifying SSBs/CSI-RSs and select one SSB/CSI-RS among the qualifying SSBs/CSI-RSs based on a scheduling opportunity of the associated ROs and a power usage on the UE side.

Abstract: Aspects are provided allowing a MSIM UE to transmit a controlled pattern of fake HARQ-ACK and a controlled RLC status report in response to un-decoded data transmissions from a base station, while suspending SRS antenna switching during performance of an activity in a different network subscription, in order to relieve MCS penalties in response to such suspension while minimizing RLC holes. The UE sends a plurality of SRSs to a base station in a first network using a first SIM of the UE, where each of the SRSs is sent using a different antenna. The UE suspends SRS transmission from the different antennas while performing an activity in a second network using a second SIM of the UE. The UE sends a HARQ-ACK to the base station while the SRS transmission is suspended in response to at least one of a plurality of un-decoded data transmissions from the base station.

Abstract: Aspects relate to random access channel procedures. In some examples, if a user equipment (UE) has not successfully received a random access channel (RACH) downlink message prior to the end of a random access window for a first RACH attempt, the UE may elect to proceed with a second RACH attempt. For example, the UE may determine whether there are any remaining downlink symbols available during the random access window to receive the RACH downlink message. If not, the UE may retransmit a physical RACH (PRACH) preamble.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine to initiate a random access channel (RACH) procedure with a base station (BS). The UE may determine, based at least in part on determining to initiate the RACH procedure, whether a timing alignment timer, associated with a timing alignment of the UE and the BS, is expired. The UE may initiate the RACH procedure using the timing alignment based at least in part on determining that the timing alignment timer is not expired. Numerous other aspects are provided.
