摘要： A method includes generating first and second data units corresponding to first and second PHY modes, respectively. Generating the first data unit includes FEC encoding first information bits, mapping the FEC-encoded bits to first constellation symbols, and generating first OFDM symbols to include the first constellation symbols. The first OFDM symbols utilize a first tone spacing, and include a first number of non-zero tones collectively spanning a first bandwidth. Generating the second data unit includes FEC encoding second information bits, block encoding the FEC-encoded bits, mapping the block-encoded bits to second constellation symbols, and generating second OFDM symbols to include the second constellation symbols. The second OFDM symbols utilize the first tone spacing, and include a second number of non-zero tones collectively spanning a second bandwidth less than the first bandwidth. The second number of non-zero tones is less than the first number of non-zero tones.

摘要： Systems and techniques relating to wireless communications are described. A described technique includes obtaining data for a transmission to a wireless communication device. The wireless communication device can be configured to process incoming transmissions based on an aggregate data unit format that specifies signaling for aggregating multiple medium access control (MAC) data units. The technique includes, in a physical (PHY) frame, an aggregate data unit that is based on the data and the aggregate data unit format, the aggregate data unit including a single MAC data unit. The technique includes, in the PHY frame, an indication to signal that the MAC data unit in the aggregate data unit is singular and to cause the wireless communication device to accept the aggregate data unit without a corresponding block acknowledgement agreement.

摘要： In a method for generating a preamble (100) of a data unit for transmission via a communication channel, an indication of a first number of spatial or space-time streams is included in a first field (VHT-SIGl) of the preamble. The first number of spatial or space -time streams corresponds to transmission of the data unit to a first receiver. One or more training sequences (VHT-LTFl....N) are included in a second field of the preamble. The preamble is formatted such that the first field of the preamble will be transmitted prior to the second field of the preamble being transmitted.

摘要： The present disclosure includes systems and techniques relating to wireless communications. A described system, for example, includes a device configured to transmit signals, in a frequency band, to the wireless communication devices. The signals can include spatially steered first signals that concurrently provide data to the wireless communication devices.

摘要： A set of channels is scanned, each channel in the set having a first bandwidth. When it is determined that one or more channels in the set of channels are not being utilized by one or more other wireless communication systems, a channel not being utilized is selected as a primary channel for a wireless communication system. When it is determined that all channels in the set of channels are being utilized by one or more other wireless communication systems, (i) a channel in the set that is aligned with a primary channel of another wireless communication system is selected as the primary channel, or (ii) a channel in the set that overlaps with a secondary channel of another wireless communication system is selected as the primary channel, where the secondary channel of the other wireless communication system has a bandwidth greater than the first bandwidth.

摘要： In a method for transmitting channel feedback data from a receiver to a transmitter, channel data for a plurality of orthogonal frequency division multiplexing (OFDM) tones for one or more spatial or space-time streams corresponding to the communication channel is determined. A compressed form of the channel data is determined. Determining the compressed form includes determining a plurality of angle values associated with the one or more spatial or space-time streams and the one or more OFDM tones of the plurality of OFDM tones. For each of the one or more spatial or space time streams, a per-tone signal to noise ratio (PT-SNR) associated with one or more OFDM tone of the plurality of OFDM tones is determined, and an average signal to noise ratio (avg-SNR) is determined by averaging signal to noise ratio (SNR) values corresponding to one or more OFDM tones of the plurality of OFDM tones. A feedback report is generated to include at least i) the plurality of angle values corresponding to the one or more spatial or space-time streams and the one or more OFDM tones, ii) the PT-SNRs corresponding to the one or more spatial or space-time streams and the one or more OFDM tones, and iii) the avg-SNR corresponding to the one or more spatial or space-time streams. The feedback report is included in a data unit to be transmitted from the receiver to the transmitter.
