Abstract: A method performed by a multi-subscriber identity module (MUSIM) user equipment (UE) for continuing operation of the MUSIM UE in a first mode, the MUSIM UE including a first SIM and a second SIM, and the method including transmitting, by the MUSIM UE, an uplink signalling message in response to determining a trigger condition has been satisfied, the uplink signalling message including one of compatible band information for the first SIM and the SIM, or one or more other stacks serving band information associated with the second SIM, receiving, by the MUSIM UE from a network, a radio resource control (RRC) reconfiguration signalling message for performing at least one activity at the first SIM in response to the transmitting the uplink signalling message, and performing, by the MUSIM UE, the at least one activity based on the RRC reconfiguration signalling message.

Abstract: A method for determining a number of paths between a Radio Frequency Integrated Circuit (RFIC) and a plurality of Subscriber Identity Modules (SIMS) of a User Equipment (UE), the plurality of SIMS including a primary SIM and a secondary SIM, the method including detecting, by the UE, at least one event associated with the secondary SIM, determining, by the UE, a tune away duration associated with the primary SIM based on the at least one event associated with the secondary SIM, determining, by the UE, an amount of resource loss by the primary SIM and a data throughput reduction of the primary SIM based on the tune away duration, and determining, by the UE, the number of paths between the RFIC and the plurality of SIMS based on the amount of resource loss by the primary SIM and the data throughput reduction of the primary SIM.

Abstract: Some example embodiments disclose methods for improving Paging Type2 performance in Dual Sim Dual Standby (DSDS) devices, wherein the methods include transmitting a status Packet Data Unit (PDU) for a Signaling Radio Bearer (SRB) to a network; initiating a first timer in response to the transmitting the status PDU; blocking a radio frequency tune away to a first Subscriber Identity Module (SIM) if one or more missing PDUs are not received before expiry of the first timer; initiating a second timer in response to the blocking the RF tune away; and retaining, by a second SIM, radio frequency resources until expiry of the second timer or the one or more missing PDUs are received from the network.
