Abstract: Methods for improving the time to acquire an identity of a base station by a mobile station, by relying on locally-unique attributes of the base stations instead of globally-unique attributes of the base stations, are presented. In some embodiments, data may be requested, the data may contain a globally unique attribute of a base station, a first locally unique attribute of the base station, and a second locally unique attribute of the base station. In some embodiments, data may be received in response to the request, the data may contain at least the first locally unique attribute and the second locally unique attribute. It may then be determined that the data did not contain the globally unique attribute, and an identity of the base station based at least in part on the first locally unique attribute and the second locally unique attribute may be acquired.

Abstract: In a TD-SCDMA user equipment (UE) with multiple receive chains, receive diversity may be implemented where multiple receive chains may simultaneously activate to receive downlink signals. Receive diversity may be enabled when single chain reception provides undesired results and when receive diversity will not impact power consumption too much. A state machine controls receive diversity operation based on operating conditions such as control channel activity, successful control channel decoding, signal-to-interference ratio, and other factors.

Abstract: Methods and apparatuses are presented for managing a multi-subscriber identity module (SIM) user equipment (UE) such that data throughput may be improved in a dual-SIM, dual active (DSDA) scenario. For example, a method is presented that includes acquiring first timing information of a first subscription and second timing information of a second subscription. Additionally, the example method may include detecting a first conflict between communications of the first subscription and the second subscription in a time slot of a first time interval. Moreover, the example method may include estimating one or more additional conflicts in one or more subsequent time intervals based on timing of the time slot, the first timing information, and the second timing information. Further, the example method may include respectively adjusting one or more transmit block sizes (TBS) for each of the one or more subsequent time intervals.

Abstract: A user equipment (UE) may reducing the interference and improve the random access of the multiple users in the network. In some instances, the UE adjusts a timing advance and/or guard period values to reduce the interference experienced in a particular guard period. The adjustment is based on selecting a timing advance parameter for uplink synchronization based at least in part on an interference distribution in a guard period of a frame in a TD-SCDMA network.

Abstract: The various embodiments provide methods implemented in a MSMA communication device for managing a victim subscription's de-sense by proactively implementing an RF coexistence management strategy on the victim subscription when an RF coexistence event starts. In various embodiments, a MSMA communication device may implement an RF coexistence management strategy by determining when an aggressor subscription will de-sense a victim subscription and configuring the victim to anticipate and mitigate de-sense during the aggressor's transmissions. Thus, the various embodiments may provide dramatic improvements to the victim's overall reception performance and overall user experience.
