A wireless communication device having a first SIM and a second SIM and a radio frequency (RF) resource including multiple receive chains and at least one transmit chain may detect, during a connection to a first network associated with the first SIM, a start of a communication activity associated with the second SIM that uses one or more transmit chains and one or more of the receive chains. The wireless communication device may determine whether a carrier frequency of a cell serving the network associated with the first SIM is within a downlink frequency range supported by an unused receive chain of the RF resource. If not, the wireless communication device may identify a neighbor cell of the first network with a carrier frequency within a downlink frequency range supported by an unused receive chain of the RF resource, and attempt to camp the first SIM on that neighbor cell.

Systems and methods for maintaining service on multiple SIMs in a wireless communication device operating in a multi-SIM multi-standby (MSMS) mode

Certain aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless communication device may determine, when involved in a multimedia broadcast or multicast service, a set of parameters relating to the state of the wireless communication device. In some aspects, the wireless communication device may determine to decode a signal associated with the multimedia broadcast or multicast service during a measurement gap based at least in part on the set of parameters. In some aspects, the measurement gap may be a gap configured for performing an intra-radio access technology (IRAT) or inter-frequency cell measurement.
