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.
