Abstract: A method for decoding an orthogonal frequency division multiplex (OFDM) data unit is described. OFDM symbols of the OFDM data unit are received that include a first OFDM symbol that corresponds to a legacy signal field followed by a second OFDM symbol that corresponds to a candidate signal field. It is determined whether the candidate signal field corresponds to a repetition of the legacy signal field. At least some of the OFDM symbols of the OFDM data unit are decoded according to a first communication protocol indicated by the determination of whether the candidate signal field corresponds to the repetition of the legacy signal field.

Abstract: Systems and methods for performing efficient blind decoding. A first plurality of decision metrics corresponding to a first repetition of periodic decoding information is stored. The first plurality of decision metrics is grouped into sequential portions. A plurality of combined versions of the sequential portions is stored into combining buffers arranged in sequence. Each combined version is associated with a different sequence of timing information. A first of the plurality of combined versions stored in a first of the combining buffers is combined with a second version of a second plurality of decision metrics that corresponds to a second repetition of the periodic decoding information. The second version is associated with timing information adjacent in the timing information sequence to the timing information associated with the first combined version. The data is decoded based on information in the combining buffers.

Abstract: Methods and systems are disclosed for transmitting high efficiency signals. The method includes creating a first signal and a second signal each comprising a plurality of information fields. The method includes determining respective intervals for repeated transmissions of each of the first signal and the second signal. The method includes determining whether a first transmission of the repeated transmissions of the first signal will be consecutively followed by a second transmission of the repeated transmissions of the second signal. The method includes adding scheduling information, based in part on determining the first transmission will be consecutively followed by the second transmission, indicating that the first transmission will be consecutively followed by the second transmission.

Abstract: A computer readable storage medium or media stores machine readable instructions that, when executed by one or more processors, cause the processors to generate, using reference signals received via a first communication channel from a first communication device to a second communication device, an estimate of the first communication channel using the received reference signals, calculate one or more transmit beamforming vectors using the estimate of the first communication channel, and utilize the one or more transmit beamforming vectors to process signals to be transmitted via a second communication channel from the second device to the first device. The first device processes the signals to be transmitted from the second device to the first device according to a model H ei, where H is a matrix representing the second communication channel and ei is a vector with all components of ei, except an ith component, being equal to zero.
