摘要： Certain aspects of the present disclosure propose transmitting a feedback message to an access point. The feedback may comprise a beamforming extension field, which may carry per tone signal to noise ratio of a station. For certain aspects, the station transmitting the per-tone SNR may be a single user (SU)-capable device. For certain aspects, the station may indicate to the access point whether or not it has a maximum likelihood (ML) receiver.

摘要： A communication device for allocating tones is described that includes a processor and instructions in memory in electronic communication with the processor. The communication device determines whether a bandwidth for signal transmission is 20, 40, 80 or 160 megahertz (MHz). The communication device respectively allocates tones for 20, 40, 80 or 160 MHz as follows: for a very high throughput (VHT) signal A1 (VHT-SIG-A1): 52, 104, 208, 416; a VHT signal A2 (VHT-SIG-A2): 52, 104, 208, 416; a VHT short training field (VHT-STF): 12, 24, 48, 48; one or more VHT long training field(s) (VHT-LTF(s)): 56, 114, 242, 484; a VHT signal B (VHT-SIG-B): 56, 114, 242, 484; and a data field (DATA): 56, 114, 242, 484. The communication device also transmits the signal.

摘要： Aspects of the present disclosure relate to techniques for generating responses to extended length frames having increased symbol lengths without changing the short interframe space duration. According to certain aspects, a method for transmitting an extended length frame generally includes generating a packet having a preamble decodable by a first type of device having a first set of capabilities and a second type of device having a second set of capabilities, wherein at least a first portion of the packet is generated using an increased symbol duration or increased cyclic prefix relative to a second portion of the packet generated using a standard symbol duration or standard cyclic prefix and the packet includes padding symbols after the first portion, and outputting the generated packet for transmission.

摘要： Certain aspects of the present disclosure provide methods and apparatus for uplink (UL) multiuser multiple-input, multiple-output (MU-MIMO) transmissions in a High Efficiency WLAN (HEW) system. One example method generally includes generating a packet having a preamble portion and transmitting the packet. The preamble portion typically includes a long training field (LTF); a first signal (SIG) field subsequent to the LTF; one or more other LTFs located subsequent to the first SIG field; and at least one second SIG field, wherein all SIG fields in the preamble portion, other than the first SIG field, are subsequent to the one or more other LTFs. Another example method generally includes receiving, from an apparatus, a packet having a preamble portion comprising tone-interleaved LTFs; and performing frequency offset adjustment on the packet based on the tone-interleaved LTFs.
