摘要： A communication device receives a physical layer (PHY) protocol data unit (PPDU). The PPDU includes i) a PHY preamble and ii) PHY data portion that includes one or more PHY midambles, and the PHY preamble includes i) an indication of a length of the PPDU, typically in the L-SIG field, and ii) an indication of a periodicity of PHY midambles in the PHY data portion, for instance as a new field within the HE- SIG-A field. The communication device calculates a number of PHY midambles in the PPDU using i) the indication of the length of the PPDU, and ii) the indication of the periodicity of PHY midambles. The communication device calculates a reception time for the PPDU using the calculated number of PHY midambles, and processes the PPDU using the calculated reception time.

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 wireless local area network (WLAN) communication by a first WLAN communication device is described. A first media access control (MAC) data unit is generated at the first WLAN communication device. The first MAC data unit is transmitted from the first WLAN communication device to a second WLAN communication device via a first WLAN communication channel having a first radio frequency (RF) bandwidth. A second MAC data unit is received at the first WLAN communication device from the second WLAN communication device via a second WLAN communication channel having a second RF bandwidth that does not overlap the first RF bandwidth. The second MAC data unit corresponds to an acknowledgment of the first MAC data unit from the second WLAN communication device.
