摘要： Systems, methods, and devices for acknowledging communications from a plurality of wireless devices in a wireless network are described herein. In some embodiments, an access point for the wireless network transmits a group acknowledgment (ACK) to indicate whether communications (packets) from the plurality of wireless devices have been received or correctly decoded within some time interval. Each wireless device may have a different time interval associated with it. For some embodiments, the time interval for a wireless device is relative to when a previous group ACK was sent. A group ACK may include a bitmap. In some embodiments, the bitmap indicating whether a communication has been received or correctly decoded may be transmitted as part of a beacon.

摘要： One aspect of the disclosure provides a method for wireless communication by a station or wireless device. The method includes waking from a sleep state. Further, the method includes determining an availability of a transmission medium. In addition, in response to determining that the transmission medium is not available, the method can include determining a sleep time period, entering a second sleep state based on the sleep time period, and freezing a backoff counter for the duration of the second sleep state.

摘要： A base station in a cellular wireless communications system uses one or more control algorithms to control a transmission pattern of a 1xRTT or DO discovery beacon. The transmission pattern enables access terminals using any one of multiple wake-up periods and wake-up offsets to discover all macrocell frequencies in a finite amount of time. In addition, for base stations allocating a single transmit chain to both 1xRTT and DO beacons, the transmission pattern enables a definite maximum discovery time for both 1xRTT and DO beacons for all access terminals entering the base station coverage.
