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.

Abstract: Aspects of the present disclosure can improve the round trip time delay of reverse link transmissions of an access terminal. The access terminal determines a first traffic-to-pilot power (T2P) ratio after a session negotiation. Then, the access terminal determines a second T2P ratio of a first subpacket of a physical layer packet, wherein the second T2P ratio may be boosted relative to the first T2P ratio. The access terminal transmits the at least one subpacket at the second T2P ratio utilizing a reverse link. Therefore, the physical layer packet may be early terminated, and round trip time delay of the reverse link may be reduced.
