摘要： A first communication device associated with a first communication network determines that a second communication device associated with a second communication network is located proximate to the first communication device. The first communication device generates a data unit that includes information indicating i) a color identifier of the second communication network, the color identifier usable to identify transmissions from the second communication network, and ii) that a dynamic clear channel assessment (CCA) procedure should not be used for transmissions from the second communication network. The first communication device transmits the data unit to at least one other communication device associated with the first communication network such that the at least one other communication device associated with the first communication network does not use the dynamic CCA procedure for transmissions identified as being from the second communication network.

摘要： Embodiments described herein provide a method for resource unit signaling with reduced data bits in a wireless local area network. At a wireless transceiver, a data frame may be obtained for transmission. The data frame includes a first preamble portion and a second preamble portion compliant with a wireless local area network communication protocol. When an available resource unit for transmitting the data frame is less than an allowed bandwidth, the first preamble portion and the second preamble portion may be configured with resource unit signaling bits. When the available resource unit is greater than or equal to the allowed bandwidth, the resource unit may be virtually divided into a plurality of channels. At least one of the first preamble portion and the second preamble portion may be configured with a first number of bits representing a number of users spatially multiplexed on a channel from the plurality of channels.

摘要： A method for transmitting a subchannel availability for an uplink (UL) multi-user (MU) transmission is described. An availability of one or more subchannels of an orthogonal frequency division multiplex (OFDM) channel are determined by a first communication device for the UL MU transmission. A High Throughput (HT) Control field of a media access control (MAC) header that includes an indication of the determined availability of the one or more subchannels is generated by the first communication device. A MAC protocol data unit (MPDU) that includes the HT Control field is generated by the first communication device. The MPDU is transmitted by the first communication device to a second communication device via the OFDM channel for a subsequent allocation of radio resources for the UL MU transmission by the second communication device.
