Certain aspects of the present disclosure provide techniques for handover timelines and power optimization for user equipment (UE) in multiple subscriber identity module (MSIM) dual receive (DR) scenarios. An example method, performed by a UE, includes entering a DR mode in which a first subscriber identity module (SIM) is active in a first radio access technology (RAT) and a second SIM is idle in a second RAT, identifying one or more channel frequencies, of a neighbor channel frequency list, that are incompatible with the DR mode, and performing a channel measurement procedure with the second SIM, on a subset of the neighbor channel frequency list that does not include the one or more channel frequencies that are incompatible with the DR mode.

Methods and devices are disclosed for implementing opportunistic mobile receive diversity ('OMRD') on a multi-SIM wireless device. The wireless device may receive a request from a protocol stack associated with the first SIM to utilize the second RF resource for receive diversity, and determine whether a protocol stack associated with the second SIM currently has a lower priority than the protocol stack associated with the first SIM. Upon determining that the protocol stack associated with the second SIM currently has a lower priority than the protocol stack associated with the first SIM, the wireless device may grant control of the second RF resource to the protocol stack associated with the first SIM. Granting control may provide, to the protocol stack associated with the first SIM, a capability to enable and disable receive diversity using the first and second RF resources.
