Abstract: Methods and corresponding apparatuses for LTE's WLAN mobility set prioritization are discussed. The method includes detecting an integrated WLAN and a legacy WLAN, measuring the connection quality of the integrated WLAN and/or the connection quality of the legacy WLAN, and determining whether to select the legacy WLAN over the integrated WLAN based on the measurement results. The method further includes detecting a WWAN using both licensed and unlicensed spectrum, and refraining from connecting to the legacy WLAN in response to the detecting.

Abstract: Methods and apparatus for offloading traffic from a cellular network to a wireless local area network (WLAN) are described. One example method generally includes receiving, from a serving base station, a request to measure one or more WLAN access points (APs), determining one or more metrics for the WLAN APs, comparing the metrics for the WLAN APs to a threshold, and reporting metrics for at least a first AP of the WLAN APs if the metrics for the first AP exceed the threshold.

Abstract: Techniques for aggregating heterogeneous carriers in a wireless communication system are disclosed. A mobile device may receive a configuration for aggregating a plurality of component carriers including one or more cellular carriers and a wireless local area network (WLAN) carrier. The one or more cellular carriers may include LTE carriers, and aggregation may be performed at a sub-IP protocol layer of operation. In one aspect, protocol entities may be modified to perform quality of service determinations, carrier selection, traffic mapping, or the like, in view of the different capabilities and characteristics of the heterogeneous carriers in the carrier aggregation configuration.

Abstract: Systems and methodologies are described that facilitate processing service data units (SDU) in-order during communication handover in wireless networks. In particular, for mobile devices using re-transmission schemes, SDUs can be processed in-order by indicating to a target base station an index of a last SDU received in-order before handing off communication to the target base station. Additionally, SDUs received subsequent to one or more non-acknowledged SDUs can be forwarded to the target base station. Utilizing this information, the target base station can determine one or more SDUs the mobile device is preparing to re-transmit and can wait for this SDU before processing subsequently received SDUs. Also, a timer can be utilized to end a waiting period for the SDU.

Abstract: Techniques for avoiding collision of traffic in a wireless network are described. A station detects for synchronization of its traffic with traffic of other stations. The station may detect for synchronization based on, e.g., percentage of first transmission failures, counters indicative of statistics of transmitted frames, and/or other information. The station may confirm synchronization of its traffic, e.g., by monitoring for traffic from another station during a service period for the station. The station adjusts transmission of its traffic when synchronization is detected to avoid collision with the traffic of the other stations. The station may delay transmission of its traffic by a predetermined amount of time, by a pseudo-random amount, or until after the other stations finish their transmissions.

Abstract: An application may be associated with an application endpoint that is accessed via a wireless local area network. In this disclosure, a wireless station may select and associated with one of a plurality of access points that provides better application throughput to the application endpoint. The application throughput may be based upon a combination of the wireless link rate (between the wireless station and the access point) as well as a measured application data rate (from the access point to the application endpoint). An access point may measure and advertise application data rates for a plurality of application endpoints, including one or more servers coupled to the local area network, a gateway to a wide area network, and/or a server coupled to the wide area network.
