摘要： A communication device sets a first channel access timer to a first duration in which at least a first portion of a communication channel is expected to be busy, the first timer corresponding to a first one of a plurality of component channels of the communication channel. The communication device also sets a second channel access timer to a second duration in which at least a second portion of the communication channel is expected to be busy, the second timer corresponding to a second one of the plurality of component channels. The communication device counts down the first timer and the second timer. When at least one of the first timer and the second timer reaches zero, the communication device determines whether one or more of the component channels are idle, and transmits at least one signal in at least one of the component channels determined to be idle.

摘要： An access point generates a management communication frame, that includes information indicating network parameters of a wireless communication network, for transmission in an operating channel of the wireless communication network. The operating channel including i) at least one primary component channel used at least for synchronizing with client stations associated with the access point and ii) at least one scanning channel specified, by the first communication protocol, to be used for scanning by client stations not associated with the access point. The access point generates a physical layer data unit to include the management communication frame, and transmits the physical layer data unit in the at least one scanning channel, specified by the first communication protocol, to allow discovery of the wireless communication network by client stations that are not associated with the access point.

摘要： In a wireless communication network that operates according to a communication protocol that defines one or more first transmission modes that provide extended range communications as compared to one or second transmission modes defined by the communication protocol, a communication device generates a communication frame that includes information indicating that the one or more first transmission modes should not be used when transmitting in the wireless communication network. The communication device transmits the communication frame to instruct one or more other communication devices in the wireless communication network to not use the one or more first transmission modes when transmitting in the wireless communication network.

摘要： A first communication device in a first wireless network determines a transmit power for transmitting a first packet during a spatial reuse opportunity corresponding to a transmission in a second wireless network. Determining the transmit power includes using a spatial reuse parameter, indicative of an acceptable interference level in the second wireless network, included in a second packet transmitted by a second communication device in the second wireless network. The first communication device generates the first packet to include information to indicate to a third communication device, that is an intended receiver of the first packet, to not transmit an acknowledgment of the first packet according to a normal acknowledgment procedure during the spatial reuse opportunity. The first communication device transmits the first packet at the determined transmit power, and receives the acknowledgement from the third communication device, the acknowledgement having not been transmitted according to the normal acknowledgment procedure.

摘要： A method for operation of a first communication device in a wireless local area network (WLAN) communication channel, having a plurality of component channels, between the first communication device and a second communication device is described. A first physical layer (PHY) protocol data unit (PPDU) and a second PPDU, distinct from the first PPDU, are generated. The first PPDU and second PPDU are transmitted simultaneously to the second communication device over the WLAN communication channel, including: transmitting the first PPDU via a first component channel within a first radio frequency (RF) channel segment that occupies a first frequency bandwidth, and transmitting the second PPDU via a second component channel within a second RF channel segment that occupies a second frequency bandwidth that does not overlap the first frequency bandwidth segment, and is separated from the first frequency bandwidth segment by a frequency gap.

摘要： A communication device generates a first data unit that spans a first bandwidth, and transmits the first data unit during a transmit opportunity (TXOP) to at least one other communication device. The communication device subsequently determines, based on respective values of TXOP duration fields included in respective physical layer (PHY) preambles of one or more data units previously transmitted during the TXOP, whether a second bandwidth of a second data unit to be transmitted by the communication device during the TXOP can be greater than the first bandwidth of the first data unit. In response to determining that the second bandwidth of the second data unit can be greater than the first bandwidth of the first data unit, the communication device generates the second data unit to span the second bandwidth greater than the first bandwidth, and transmits the second data unit during the TXOP.

摘要： A communication device determines an overall bandwidth of an operating channel for a wireless local area network (WLAN), where the overall bandwidth spans a plurality of sub-channels. The communication device determines that one or more sub-channels within the overall bandwidth will not be used for the operating channel, and generates a packet that includes i) a first subfield that indicates the overall bandwidth of the operating channel, and ii) a second subfield that indicates the one or more sub-channels within the overall bandwidth that will not be used for the operating channel. The communication device transmits the packet to inform one or more other communication devices in the WLAN of the operating channel for the WLAN, the operating channel.
