A method can include, in an access point (AP) configured to control data transfers for associated stations (STAs) in time intervals, storing a unique identifier and quality-of-service (QoS) requirement for each STA of a first set in a nonvolatile memory of the AP. In response to a STA associating with the AP, if the associating STA is in the first set, allocating time for the STA in the time intervals to meet the QoS requirement of the STA without receiving transmitted QoS data from the STA, and if the associating STA is not in the first set, establishing a QoS for the STA having a lower priority than any associated STAs of the first set. Corresponding systems and devices are also disclosed.

Methods, systems and devices for providing differentiated quality of service for wireless communication devices

A method can include, by operation of a station wireless device (STA): receiving a plurality of different broadcast transmissions, determining an air time availability of each of a plurality of access point devices (APs) from data included within the broadcasts, for each of the plurality of APs, estimating a data rate for the STA with respect to the AP from traffic data included in at least one broadcast transmission from the AP, selecting one AP from the plurality of APs based on predetermined traffic metrics for the plurality of APs, and associating with the selected AP. Corresponding devices and systems are also disclosed.

Devices, systems and methods for throughput oriented association with access point devices

A method includes comparing a first battery life value of a first wireless device with a second battery life value of a second wireless device, and in response to determining, based on the comparing, that the first battery life value is less than the second battery life, adjusting a communication schedule so a duration of awake state operation of the first wireless device is less than a duration of awake state operation of the second wireless device.

Apparatus, systems, and methods for battery life based wireless communication scheduling

A method can include negotiating a target wake time (TWT) with a TWT session period (TWT SP) duration and generating mask data that inhibits communications according to a second standard during at least a portion of TWT SP. A method can further include, by operation of second communication circuits, generating a communications mask from mask data received from WLAN circuits, in response to the timing signal, synchronizing the communications mask with the TWT SP, and in response to the communications mask, inhibiting communications according to the second standard during at least a portion of the TWT SP. Corresponding devices and systems are also disclosed.

WLAN coexistence with other standards using communications mask aligned with target wake time

A method can include at a first station in a wireless network, receiving path loss (PL) transmissions from at least a second station, dynamically changing power for transmissions from the first station to the second station based on the received PL information, determining PL values for transmissions received at the first station from other stations, and sending PL transmissions from the first station that include the determined PL values for at least one other station. The PL transmissions are configured to be received by stations of the same wireless network and stations of a different wireless network. Corresponding devices and systems are also disclosed.

Methods, systems and devices for varying wireless transmit power based on path loss information

Systems and methods compare a first battery life value associated with a first wireless device with a second battery life value associated with a second wireless device. Based on the comparison, systems and methods adjust a communication schedule by allocating timeslots of the communication schedule to the first wireless device and transmit the adjusted communication schedule to the first wireless device.

Two methods for energy-efficient idle listening enhancement for WLAN systems are provided. The first method performs a change of operation of a station (STA) from an active mode to an idle listening mode without notifying the change to an access point (AP) associated with the STA. In the idle listening mode, the AP may transmit frames to the STA using a higher bandwidth, but the STA can only sense channels in a lower bandwidth to save energy. The second method transmits a frame to the AP associated with the STA to notify the AP the change of operation of the STA from the active mode to the idle listening mode. In the idle listening mode, the AP may transmit frames to the STA using the lower bandwidth, and the STA can only sense channels in the lower bandwidth to save energy.

Energy-efficient idle listening schemes

Systems, methods, and devices schedule requests associated with wireless communications devices. Methods include receiving a plurality of requests from a plurality of wireless communications devices that is compatible with an 802.11 transmission protocol, where each request of the plurality of requests includes a proposed service period and proposed service interval. Methods further include generating, using a processing device, a plurality of quantization factors by quantizing the proposed service interval included in each of the plurality of requests, determining, using the processing device, a common service interval based, at least in part, on the plurality of quantization factors and a basic service unit, and generating, using the processing device, an allocation pattern to allocate the proposed service periods within the common service interval.
