摘要： A method for acknowledging a first medium access control (MAC) service data unit (MSDU) is described. A first aggregate MAC protocol data unit (A-MPDU) of a first orthogonal frequency division multiple access (OFDM A) data unit is received at a first communication device from a second communication device. The first A-MPDU includes a first fragment of a plurality of fragments of the first MSDU. A second A-MPDU of a second OFDMA data unit is received at the first communication device from the second communication device. The second A-MPDU includes a second fragment of the plurality of fragments and the second fragment is an end fragment of the plurality of fragments. A fragment acknowledgment data unit is generated by the first communication device to acknowledge receipt of each of the plurality of fragments of the first MSDU. The fragment acknowledgment data unit is caused to be transmitted to the second communication device.

摘要： A first communication device determines whether the first communication device is to use a first channel access mode or a second channel access mode for accessing a communication channel when the first communication device is triggered for uplink transmission by a second communication device. The first communication device receives a trigger frame from the second communication device. The first communication device transmits, to the second communication device, a data unit triggered by the trigger frame, including using the determined one of the first channel access mode or the second channel access mode to gain access to the communication channel.

摘要： An access point generates a trigger frame to trigger an uplink multi-user (MU) transmission by multiple client stations. The access point generates the trigger frame to include a common information field and multiple per-station information fields. The access point generates the common information field to include (i) a subfield that indicates a bandwidth of the uplink MU transmission, and (ii) information that indicates a guard interval and a long training field (LTF) mode to be used by the multiple client stations for the uplink MU transmission, and generates each per-station field to include respective frequency allocation information that indicates respective frequency resources to be used by the respective client station for the uplink MU transmission. The access point transmits the trigger frame to the multiple client stations to trigger the uplink MU transmission by the multiple client stations.

摘要： A wireless communication device including a first media access control device and a first transceiver. The first media access control device is configured to selectively generate a first timestamp having a first length and a second timestamp having a second length. The first timestamp indicates a first synchronization time of the wireless communication device, the second timestamp indicates only a first portion of the first synchronization time, and the first synchronization time is used by a client station to synchronize timing between the wireless communication device and the client station. The first media access control device is further configured to generate a beacon including either the first timestamp or the second timestamp, and an indication of whether the beacon includes the first timestamp or the second timestamp. The first transceiver is configured to transmit the beacon from the wireless communication device to the client station.

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： As part of a beamforming training procedure, a first communication device transmits a beamforming training packet. The first device then receives a plurality of respective beamforming feedback packets from a plurality of second communication devices. The first device then uses the plurality of beamforming feedback packets to select a group of multiple communication devices from among the plurality of second communication devices, wherein the group is selected for simultaneous transmissions to the first communication device. The first device then transmits a synchronization signal to the group to prompt second communication devices in the group to simultaneously transmit to the first communication device at a particular time. The first device then receives simultaneous transmissions from the group responsive to the synchronization signal.

摘要： 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.
