Abstract: Methods, systems, and devices are described for assisting discovery of a wireless local area network (WLAN). A timing reference originating from a first radio technology is identified by a user equipment (UE). A WLAN receiver of the UE is woken up according to a beacon transmission schedule to listen for a beacon on the WLAN. The first radio technology is a non-WLAN radio technology, and the beacon transmission schedule is based at least in part on the timing reference.

Abstract: Methods, systems, and devices are described for using information relating to a motion state of a mobile device to inform a handover decision of the mobile device. In one aspect, a method may include obtaining motion state information of the mobile device and, based on the motion state information, generating predictive information, for example relating to whether the mobile device is moving out of a network coverage area, such as a WLAN, to a WWAN or another WLAN. The mobile device may then participate in a handover based on the predictive information. In one aspect, the mobile device may participate in the handover prior to disconnection with a serving network and/or prior to a connection quality with the serving network falling below a connection quality threshold.

Abstract: Systems and methodologies are described that facilitate providing flow control feedback for controlling downlink data transmission rates. Various schemes can be utilized to send the flow control feedback from an access terminal to a base station. For example, a control PDU (e.g., MAC control PDU, PDCP control PDU) can be generated based upon a level of resource utilization of the access terminal, and sent to the base station for controlling the downlink data transmission rate. Following this example, a type of control PDU, a value included within the control PDU, etc. can be selected as a function of the level of resource utilization. By way of another illustration, a CQI report that includes a value selected as a function of the level of resource utilization associated with the access terminal can be generated and transmitted to the base station for controlling the downlink data transmission rate.

Abstract: Systems and methodologies are described that facilitate managing interaction between paging and discontinuous reception (DRX) cycles for users operating in a communication system. As described herein, a connected mode user having an associated DRX cycle can modify its schedule for paging reception to minimize unnecessary periods of activity. For example, a user can initially schedule monitoring of paging occasions that coincide with periods of activity associated with the DRX cycle of the user. If such paging occasions are not sufficient to reach a minimum required number of monitored paging occasions, additional paging occasions can be monitored as needed by scheduling additional periods of activity and/or extending periods of activity specified in the DRX cycle. Additionally or alternatively, a network can synchronize a connected mode DRX cycle associated with a user with an idle mode paging cycle for the user, thereby providing power and performance benefits with low complexity.

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: Methods, systems, and apparatuses are described for managing interfaces for wireless communications. In one method, at least one active interface of a user equipment (UE) may be used for the wireless communications. While using the at least one active interface, a need for increased bandwidth for the wireless communications may be detected. Based at least in part upon detecting the need for increased bandwidth, at least one additional interface of the UE may be activated for use in the wireless communications. More than one of the active interfaces of the UE may be simultaneously used for the wireless communications, and may be used independent of network coordination of the active interfaces.
