Abstract: In a particular implementation, a method of wireless communication includes searching, at a user equipment (UE) having a first subscriber identity module (SIM) and a second SIM, transmit beams from a base station and receive beams from the UE to determine a subset of transmit beams. The method also includes storing indicators of the subset of transmit beams in a database accessible to the UE in response to the second SIM performing a particular operation that causes the first SIM to perform a tune away operation. The method further includes, after completion of the particular operation, performing measurement operations on the subset of transmit beams to select a particular transmit beam of the subset of transmit beams and a corresponding particular receive beam for attachment to the base station.

Abstract: Certain aspects of the present disclosure provide techniques for A method for wireless communication by a user equipment (UE), comprising initiating a timer upon reception of a first segmented packet of a plurality of packets of an RLC physical data unit (PDU) at radio link control (RLC) layer, resetting the timer when a packet data convergence protocol (PDCP) layer receives an RLC PDU from the RLC layer, and upon expiry of the timer, initiating a radio recourse control (RRC) connection reestablishment (RRE) procedure with a network.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive information identifying a recovery time associated with packet data convergence protocol (PDCP) communication using a reordering timer, wherein a distribution of recovered PDCP counts associated with the PDCP communication is associated with a configured characteristic for a packet recovery time. The UE may communicate on a link using a communication configuration associated with a correlation between the packet recovery time and a link characteristic. Numerous other aspects are described.
