    摘要: Systems and methods for generating a control signal for automatic wireless network version detection of a transmission. The control signal enables a receiver to detect the wireless network version detection of the transmission, so that the proper wireless network version is used for interpreting signaling information and decoding of the payload of the transmission. In some examples, the control signal is within a preamble of the transmission. The wireless network version can be an IEEE 802.11 version, such as proposed IEEE 802.11be. The control signal is compatible with legacy systems and can indicate the legacy signaling information by way of a Legacy Signal (SIG) (L-SIG) symbol. In some examples, the control signal can indicate the wireless network version by using an identifier symbol which is generated from at least part of, but is not identical to, the L-SIG symbol.

    摘要: Methods, devices and systems for allocating spectrum in a wireless local area network. A bit representation of the availability or unavailability of a plurality of sub-bands of a portion of frequency spectrum is generated and included in a physical layer protocol data unit, which is transmitted to a target station to allocate resource units within the portion of frequency spectrum for use by the target station. The sub-bands may be 20 MHz spectrum sub-bands for large-size resource units, or the portion of frequency spectrum may be a single 20 MHz band sub-divided into multiple sub-bands for allocating small-size resource units. A station that receives the data unit may decode the bit representation and use the allocated resource units to communicate over the wireless local area network.

    摘要: A method and apparatus for feeding back channel information from a first device to a second device in a wireless communication system are provided. The first device estimates channel parameters based on a signal received from the second device, and determines a set of angle parameters indicative of an angle representation of a V matrix, which is the right singular matrix of a singular value decomposition of an estimated channel matrix H. The angle parameters can be derived according to a Givens rotation method or Cosine-Sine decomposition. The first device applies a Trellis Coded Quantization (TCQ) scheme to map the angle parameters to a trellis. A Viterbi algorithm applied to the trellis generates quantized angle parameters which are transmitted to the second device.
