Claim:
1. A method for implementing opportunistic mobile receive diversity (“OMRD”) on a multi-subscriber identification module (SIM) wireless communication device having at least a first SIM associated with a first radio frequency (RF) resource and a second SIM associated with a second RF resource, comprising: receiving a request from a protocol stack associated with the first SIM to utilize the second RF resource for receive diversity; determining whether a protocol stack associated with the second SIM currently has a lower priority than the protocol stack associated with the first SIM; and granting control of the second RF resource to the protocol stack associated with the first SIM in response to determining that the protocol stack associated with the second SIM currently has a lower priority than the protocol stack associated with the first SIM, wherein granting control provides to the protocol stack associated with the first SIM a capability to enable and disable receive diversity using the first and second RF resources, and wherein enabling receive diversity configures the first and second RF resources to receive, while the first SIM protocol stack is not in idle mode, a downlink signal associated with the first SIM by coupling a path for signals associated with the second RF resource to one or more components that process a first RF resource signal path associated with the first SIM.
