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.

摘要： Apparatus and methods for communicating and applying training sequences are described herein. For example, provided is a method for generating a short training field (STF) sequence comprising thirty two values or less. The STF sequence can include a first subset of values including zero and non-zero values. The non-zero values can be located at indices of the first subset that are at least a multiple of two, and can be a multiple of four. The STF sequence includes a second subset of zero values that can include all values not included within the first subset. The method further includes transmitting a data unit comprising the STF sequence over a wireless channel. In another example, a method is provided that includes generating a long training field (LTF) sequence comprising thirty two values or less, and transmitting a data unit comprising the LTF sequence over a wireless channel.

摘要： A method, an apparatus, and a computer program product operable in a wireless communication system are provided in which a first signal is generated for transmission to a wireless node to enable the wireless node to determine a first preferred beam pattern. A second preferred beam pattern is determined from a second signal received from the wireless node. The apparatus communicates with the wireless node through at least one of the first or second preferred beam pattern.

摘要： Certain aspects of the present disclosure relate to techniques for medium reservation in the case of multi-user (MU) communications. Multiple mechanisms are supported for protecting MU transmissions, wherein appropriate control messages can be exchanged between an access point and served user stations before transmitting downlink data packets.

摘要： Systems and methods for communicating packets having a plurality of formats are described herein. In some aspects, a signal (SIG) field in the preamble of a packet may indicate whether an extension field, such as an extension SIG field or SIG-B field, is included in the packet. In another aspect, one or more detectors may be used to auto-detect packets formatted as one of at least two different formats based on a short training field (STF) of a received packet. In some aspects, along training field (LTF) in the preamble of a packet may indicate whether the payload is repetition coded.
