A wireless device operates as a wireless station (STA) associated with a first access point (AP) of one basic service set (BSS) in a first set of intervals, and as a second AP of another BSS in a second set of intervals. The wireless device, operating as a STA receives, in a first interval of the first set of intervals, indication that data is buffered in the first AP for the STA. The wireless device, operating as a STA issues, in a second interval of the first set of intervals, a request to the first AP for at least some portion of the buffered data. The second interval is later than the first interval and separated from the first interval by a third interval, the wireless device operating as the second AP in the third interval. Due to such operation, efficiencies such as reduced data loss can be obtained.

Efficient dual-mode operation of a wireless device as an access point and a wireless station of respective WLAN networks

A dual-mode device may compute an expected time instance of arrival of a first beacon based on prior received beacons. If the first beacon is received at an actual time instance which is in variance with the expected time instance, the device re-computes a sequence of future time instances of arrival of respective future beacons and schedules a sequence of station windows, with each station window to cover the corresponding future time instance of the sequence of future time instances and to have a desired first period. The dual-mode device operates in station mode in the sequence of station windows and in the AP mode in a sequence of AP windows, wherein each station window of the sequence of station windows is operated alternately with each AP window of the sequence of AP windows in a TDM manner, with each AP window having a desired second period.
