摘要： A method of operating an access point includes defining a restricted access window during which stations that belong to a same infrastructure basic service set as the access point are not allowed to transmit data frames. The method further includes generating a beacon announcing the restricted access window, and transmitting the beacon to the stations that belong to the same infrastructure basic service set as the access point. The method also includes, during the restricted access window, receiving a poll frame from a first station of the stations that belong to the same infrastructure basic service set as the access point. The method further includes, subsequent to the poll frame, transmitting a data frame to the first station.

摘要： A communication device comprises a network interface including at least i) a first transmit flow unit, and ii) a second transmit flow unit. The network interface is configured to generate, using the first transmit flow unit and when in a composite channel transmit mode, a first set of OFDM tones, and generate, using the second transmit flow unit and when in the composite channel transmit mode, a second set of OFDM tones. Further, the network is configured to generate, when in the composite channel transmit mode, a composite channel OFDM symbol comprising the first and second sets of OFDM tones. The composite channel OFDM symbol includes lower-edge and upper-edge guard tones, with at least one of i) the number of lower-edge guard tones being greater than a first number of lower-edge guard tones used in a first transmit mode different than the composite channel transmit mode and greater than a second number of lower-edge guard tones used in a second transmit mode different than the composite channel transmit mode, and ii) the number of upper-edge guard tones being greater than a first number of upper-edge guard tones used in the first transmit mode and greater than a second number of upper-edge guard tones used in the second transmit mode.

摘要： Systems and techniques relating to wireless communications are described. A described technique includes monitoring wireless communication channels, including a first channel and a second channel, to produce a monitoring output, determining a first transmission period for the first channel, determining a second transmission period for the second channel, transmitting, based on the first transmission period, a first packet on the first channel to cause one or more wireless communication devices to set a transmission protection period for the first channel and the second channel based on a reception of the first packet, transmitting, based on the second transmission period, a second packet on the second channel, and monitoring, after the end of the first transmission period, for one or more acknowledgements. An end of the second transmission period can be aligned with an end of the first transmission period.

摘要： A first preamble for a first data unit includes a first long training field and a first signal field modulated according to a first technique. The first data unit is generated according to a first data unit format and includes the first preamble. A second preamble, generated for a second data unit, includes a second signal field and a second long training field. Information in the second signal field is repeated and/or the second long training field is generated so that a duration of the second long training field is longer than a duration of the first long training field. A portion of the second signal field is modulated according to a second technique or a portion of the second long training field is modulated according to the second technique to signal to a receiver that the second data unit is formatted according to a second data unit format.
