    摘要: Techniques for supporting communication over an extended range in a wireless network are disclosed. In one aspect, a station sends multiple messages of a given type for different operating modes. These messages can be detected by stations with different capabilities, which may avoid collisions between stations. In one design, a first station receives a Request-to-Send (RTS) message from a second station having data to send. The first station sends a first Clear-to-Send (CTS) message and also a second CTS message in response to the RTS message. The second CTS message has an extended range as compared to the first CTS message. The first station thereafter (i) receives data sent by the second station in response to the second CTS message and (ii) sends an acknowledgement having an extended range.

    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.
