Abstract:
A wireless communication device having a root complex, a WLAN module, a power module and an interface linking the root complex and the WLAN module, wherein the root complex is configured to implement a power management policy based upon a latency tolerance value for the WLAN module and wherein the power module is configured to adjust the latency tolerance value based upon receive and transmit parameters of the WLAN module. The power module may be configured to adjust the latency tolerance value on a per-frame basis.
Abstract:
Methods, devices, and apparatuses are described for wireless communications using a multidimensional algorithm for roaming. In one aspect, an initial set of candidate access points (APs) is produced by a station using a roaming scan. The initial set may be identified based at least in part on an initial metric (e.g., beacon signal strength). A probe signal may be transmitted by the station to at least one of the candidate APs in the initial set and information may be received in response to the probe signals. The station may then identify a reduced set from the initial set based at least in part on the received information, where the reduced set is used to select a target AP. At least one additional metric may be identified and the probe signal may be configured to obtain information corresponding to the additional metrics. This information may be used by the station to select the candidate APs in the reduced set.
Abstract:
Methods, systems, and devices are described that enable a WLAN access point (AP) to schedule packet transmissions to (or from) a mobile device taking into consideration the schedule of various other coexisting transmission/reception (Tx/Rx) activities on the mobile device. Various approaches may increase throughput at the mobile device. Various approaches also may benefit other stations associated with the same AP.
Abstract:
Disclosed are systems, methods and devices for obtaining round trip time measurements for use in location based services. In particular implementations, a fine timing measurement request message wirelessly transmitted by a first transceiver device to a second transceiver device may permit additional processing features in computing or applying a signal round trip time measurement. Such a signal round trip time measurement may be used in positioning operations.

Abstract:
This disclosure describes techniques for operating a client device to communicate with a wireless access point to validate data within a frame by comparing channel quality metrics and duration metrics to thresholds. Information received within a validity window may be treated as correctly received even if the frame fails a subsequent verification process or if reception of the frame is terminated prior to the end of the frame.
