  • Opportunistic mobile receive diversity (OMRD) in a dual-SIM dual-active (DSDA) device
    Patent number: 9544042
    Abstract: 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.
    Type: Grant
