Abstract: In various aspects, the disclosure provides the capability for a UE to implement a partial PLMN scan, providing quick results to a user's request for a manual PLMN scan, in a way that is expedited relative to the conventional method of providing PLMN results only when a full scan is completed. In further aspects, the disclosure provides for various optimizations to expedite a PLMN scan, which may be implemented either with the partial PLMN scan, or in a full PLMN scan, to further expedite the provision of PLMN scan results to the user.

Abstract: Techniques for controlling receive diversity on a wireless device are disclosed. In one aspect, one or more thresholds are determined based on one or more parameters. One or more other parameters are compared against the one or more thresholds to determine whether to enable or disable receive diversity. For example, a wireless device may determine a threshold value based on a first parameter related to communication of the wireless device. The wireless device may decide to enable or disable receive diversity based on a second parameter and the threshold value. The wireless device may receive data transmission with receive diversity when a decision is made to enable receive diversity. The first parameter may relate to characteristics of data being received by the wireless device and may be represented by percentage downlink utilization. The second parameter may relate to channel conditions and may be represented by an improvement in received signal quality with receive diversity enabled.

Abstract: Systems and methodologies are described herein that facilitate efficient transfer of quality of service (QoS) context during inter-radio access technology (RAT) handovers. In particular, techniques are described herein for establishing rules for whether a user equipment unit (UE) or an associated network should establish QoS for a mixed-mode application, identifying flow to bearer mappings when translating QoS across an inter-RAT handover, mapping QoS parameters of respective RATs, mitigating QoS depreciation upon multiple handovers, performing one or more actions if QoS is not acceptable in a new RAT, maintaining QoS during tunnel mode, and handling scenarios in which a UE moves between a RAT using network-initiated QoS and a RAT using UE-initiated QoS.

Abstract: A method, an apparatus, and a computer program product for wireless communication are provided in which user equipment performs a circuit-switched fallback procedure to connect to a CDMA2000 network. The CDMA2000 network may be selected by the UE or by the network. A plurality of PLMN IDs may be maintained, where the IDs relate to a network that includes an LTE RAN. Each PLMN ID may be associated with a CDMA2000 network sharing the LTE RAN. A CDMA2000 network may be selected for circuit-switched fallback of a user equipment operating in the LTE RAN. The user equipment may be configured to perform a circuit-switched fallback procedure on the selected CDMA2000 network. The CDMA2000 network may be selected by a mobility management entity responsive to a PLMN selection procedure. The PLMN selection procedure may be performed when the UE reports multiple-operator capability.
