Abstract: A station (STA) of a wireless local area network (WLAN) transitions implicitly between power management (PM) modes or PM states, without providing an explicit indication of the PM mode/state change to an access point (AP) of the WLAN. Transitions include changes between an active mode and a power save (PS) mode, or between an awake state and a doze state of the PS mode. Transitions occur immediately after receipt of a beacon indicating pending data for the STA, after an offset time indicated in the beacon, or at a specific wake time negotiated with the AP. After data reception is complete, the STA transitions implicitly to the PS mode or a doze state of the PS mode, after a power save inactivity timeout period or after receiving an indication that data transmission is complete.
Abstract translation: 无线局域网（WLAN）的站（STA）在功率管理（PM）模式或PM状态之间隐含地转换，而不向WLAN的接入点（AP）提供对PM模式/状态改变的明确指示。 转换包括在主动模式和省电（PS）模式之间或在PS模式的唤醒状态和打盹状态之间的变化。 在信标指示的偏移时间之后或在与AP协商的特定唤醒时间之后，在接收到指示STA的未决数据的信标之后立即发生转换。 在数据接收完成之后，STA在省电不活动超时时段之后或在接收到数据传输完成的指示之后，隐含地转换为PS模式或PS模式的打盹状态。

Abstract: In embodiments, a wireless device, such as a Wi-Fi device, transmits communication signals on secondary channels within an operational bandwidth of a wireless network, concurrent with a transmission from another wireless device on a primary channel. The wireless device may detect that a first frequency band within an operating bandwidth of a wireless network is occupied by a first transmission transmitted by a second wireless device, and determine that a second, different frequency band within the operating bandwidth of the wireless network is not occupied. In response, the wireless device may transmit a second transmission occupying the second frequency band concurrent with the first transmission. The wireless device may set a duration of the second transmission based at least in part on a determination of whether the second wireless device is configured to assess the state of all frequency bands within the operating bandwidth before beginning a subsequent transmission.

Abstract: A device and method generates a hopping scheme for mobile stations of a wireless network. The method includes receiving a number of channels N of the wireless network. The method includes generating a shuffling matrix as a function of the number of channels N, each row of the shuffling matrix being indicative of a respective one of the mobile stations, each column of the shuffling matrix being indicative of a respective broadcast time of a discovery signal in a hopping scheme. The method includes generating the hopping scheme for the mobile stations in the channels as a function of the shuffling matrix. The hopping scheme maximizes an interval between two consecutive broadcast times that any two of the mobile stations are assigned to transmit discovery signals on adjacent channels.
