    • A system and method for reliable multicast communications is disclosed herein. In one aspect, a first station may receive a first multicast frame having a first modulation and coding scheme and a first sequence number. The station may then receive a subsequent negative acknowledgement request having a second modulation and coding scheme and a indicating a second sequence number for previously transmitted multicast frame, with the second modulation and coding scheme having a lower data rate than the first modulation and coding scheme. The station may then selectively acknowledge the negative acknowledgement request based on a comparison of first sequence number and the second sequence number. In another aspect, the station transmits a negative acknowledgement if the second sequence number does not match the first sequence number and may further receive acknowledgement frame from an access point.
    • 本文公开了用于可靠多播通信的系统和方法。 在一个方面,第一站可以接收具有第一调制和编码方案和第一序列号的第一多播帧。 然后,站可以接收具有第二调制和编码方案的随后的否定确认请求,并且指示用于先前发送的多播帧的第二序列号,其中第二调制和编码方案具有比第一调制和编码方案更低的数据速率。 然后,站可以基于第一序列号和第二序列号的比较来选择性地确认否定确认请求。 在另一方面,如果第二序列号与第一序列号不一致,则站点发送否定确认,并且还可以从接入点接收确认帧。

    • A station, method, and apparatus for network detection in a wireless communication system are provided. One implementation may include a station for identifying the presence of at least one access point to associate with. The station comprises a processor configured to generate a probe message, the probe message including a scrambling seed. The processor is further configured to transmit the probe message. The processor is further configured to receive a first probe response message from each access point, the first probe response message being encoded with the scrambling seed. The processor is further configured to receive the second probe response message from each of the access points, the second probe response message from each of the access points including at least an address of the access point. The processor is further configured to identify an access point to associate with based on the second probe response messages. The processor is further configured to generate an association request to transmit to the identified access point. The processor is further configured to transmit the association request to the identified access point.
