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： A communication device receives a plurality of information bits and determines a maximum number of information bits that can be encoded such that, after the plurality of information bits have been encoded using i) a forward error correction scheme, and ii) a block coding scheme, the block coded bits fit within a single orthogonal frequency division multiplex (OFDM) symbol. The maximum number of information bits is based on a number of repetitions of coded information bits by the block coding scheme, and a number of block coded bits for the maximum number of information bits is less than a number of data tones of the single OFDM symbol. The communication device encodes the plurality of information bits using the forward error correction scheme and the block coding scheme to generate block coded bits, and generates a physical layer data unit to include the block coded bits in the single OFDM symbol.
