Abstract: 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.

Abstract: 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.

Abstract: A method is described. A block allocation that indicates a plurality of contiguous tone blocks of a wireless local area network communication channel is selected for a multi-user, multiple input multiple output (MU-MIMO) orthogonal frequency division multiple access (OFDMA) data unit. A contiguous tone block corresponds to a respective device set having at least one communication device. Respective spatial stream allocations are selected, for at least some of the blocks, that indicate a number of spatial streams for the corresponding block of the data unit. The number of streams of a block is equal to a number of communication devices of the device set that corresponds to the block. A first field is encoded and transmitted to indicate the selected block allocation and the selected spatial stream allocations. A second field is encoded and transmitted to indicate a respective device identifier for each communication device of the respective device sets.

Abstract: A communication device is configured to operate in a first wireless communication network that utilizes a communication protocol developed for use in frequency bands that are licensed by a government entity for wireless communication applications. The communication device determines whether one or more communication channels in an unlicensed frequency band are not being utilized by any second wireless communication networks, wherein the government entity does not require licenses to use the unlicensed frequency band. In response to determining that one or more communication channels in the unlicensed frequency band are not being utilized by any second wireless communication networks, the communication device selects a set of one or more communication channels in the one or more communication channels for use by the first wireless communication network, and utilizes the set of one or more communication channels for communications in the first wireless communication network.

Abstract: A first communication device receives sounding feedback packets from a plurality of second communication devices in a group of second communication devices for OFDMA communication. Each sounding feedback packet includes beamforming feedback information to be used by the first communication device for beamforming to the corresponding second communication device, and one or more quality indicators corresponding to one or more sub-channel blocks of an orthogonal frequency division multiplexing (OFDM) communication channel associated with the corresponding second communication device. Respective sub-channel blocks are allocated based on the quality indicators, to respective ones of the second communication devices in the group. The first communication device transmits an OFDMA data unit that includes respective OFDM data units directed to respective ones of the second communication devices in the group. The respective OFDM data units are transmitted in the respective sub-channel blocks allocated to the second communication devices in the group.

Abstract: 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.

Abstract: A first communication device allocates respective frequency sub-channels for subsequent orthogonal frequency division multiple access (OFDMA) communications with two or more second communication devices, including allocating a first frequency sub-channel, a second frequency sub-channel, and a third frequency sub-channel between the first frequency sub-channel and the second frequency sub-channel. The first communication device generates and transmits a first downlink OFDMA data unit configured to prompt the two or more second communication devices to transmit as part of a multi-user transmission that spans the first frequency sub-channel, the second frequency sub-channel, and the third frequency sub-channel. The first communication device receives an uplink OFDMA transmission and determines that the uplink OFDMA transmission did not include a transmission within the third frequency sub-channel. In response, the first communication device does not transmit within the third frequency sub-channel when transmitting one or more subsequent downlink OFDMA data units via the communication channel.
