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 communication device receives a signal during a backoff period of a backoff procedure, wherein the communication device is part of a first communication network. In response to determining that i) the signal is valid, ii) the signal is from another communication network, and iii) the power level of the signal does not meet a threshold that is higher than a default threshold, the communication device continues a count of a backoff timer during reception of the signal. In connection with comparing the power level of the signal to the threshold higher than the default threshold, the communication device sets a transmit power level to a reduced power level that is lower than a default power level. The communication device transmits at a transmit power level that is less than or equal to the reduced transmit power level in response to the backoff timer expiring.
