摘要： Aspects of a serial clear to send to self message procedure are presented. Aspects of a system may include a wireless local area network station (STA), which enables transmission of a channel reservation confirmation message, such as a CTS frame, via a reference RF channel, for example, a primary channel. The STA may enable transmission of one or more subsequent channel reservation confirmation messages, for example CTS frames, via a corresponding one or more subsequent RF channels, for example, a secondary channel. The STA may enable transmission of data frames via the reference RF channel and/or at least a portion of the corresponding one or more subsequent RF channels.

摘要： A method for configuring a multiple input multiple output (MIMO) wireless communication begins by generating a first preamble for a first antenna of the MIMO communication, wherein the first preamble includes a carrier detect field, a first channel select field, a first signal field, and a second signal field. The method continues by generating a second preamble for at least one other antenna of the MIMO communication, wherein the second preamble includes the carrier detect field, a plurality of channel select fields, and the second signal field. The method continues by simultaneously transmitting the carrier detect field via the first antenna and the least one other antenna. The method continues by transmitting the first channel select field and the first signal field via the first antenna. The method continues by, subsequent to the transmitting the first channel select field and the first signal field via the first antenna, transmitting the plurality of channel select fields via the at least one other antenna. The method continues by simultaneously transmitting the second signal field via the first antenna and the at least one other antenna.

摘要： A station in the WLAN monitors each transmitted frame to determine whether the frame transmission was protected by an existing outstanding airtime reservation. If a frame is transmitted without an airtime reservation and no response frame is received, the station assumes that the transmission failed due to contention, and monitors the number of contention attempts made to transmit each frame, and the number of failures to receive an acknowledgement. Based on this information, the station dynamically adjusts an RTS/CTS threshold used to determine whether or not an RTS/CTS exchange mechanism should be enabled. If a frame is transmitted during a time interval protected by an outstanding airtime reservation and no response frame is received, the station assumes that the transmission failed due to a bit error, and monitors the number of bit error rate (BER) attempts made to transmit each frame, and the number of BER failures to receive an acknowledgement. Based on this information, the station dynamically adjusts a fragmentation threshold used to determine whether or not a data frame fragmentation mechanism should be enabled.
