    摘要： Certain aspects of the present disclosure provide techniques and apparatus for generating a unified format of channel state information (CSI) feedback for Very High Throughput (VHT) wireless systems. One example method generally includes generating, at a first apparatus, a frame comprising information relating to SNR if a second apparatus is communicating with the first apparatus using single-user MIMO (SU-MIMO) or multi-user MIMO (MU-MIMO) and transmitting a signal based on the generated frame to the second apparatus. Another example method generally includes generating, at an apparatus, a structure comprising CSI, wherein the CSI includes one of a first matrix with estimates of a channel associated with the apparatus or a second matrix obtained based on singular value decomposition (SVD) of the first matrix and wherein the structure further comprises an indication of which of the first and second matrices is included in the CSI; and transmitting the structure over the channel.

    摘要： Systems, methods, and devices for wireless communication. In one aspect, an apparatus for wireless communication is provided. The apparatus includes a receiver configured to receive a wireless signal comprising a packet. At least a portion of the wireless signal is configured to be received over a bandwidth lower than or equal to 1.25 MHz. The packet is formed from at least one orthogonal frequency-division multiplexing (OFDM) symbol comprising thirty-two tones. The thirty-two tones correspond to frequency subcarriers within the bandwidth. The thirty-two tones of the at least one OFDM symbol are allocated as: twenty-four data tones, two pilot tones, five guard tones, and one direct current (DC) tone. The apparatus includes a processor configured to evaluate the wireless signal. The processor includes a transform module configured to convert the at least one OFDM symbol into a frequency domain signal using a thirty-two point mode.
