摘要： A method for establishing an uplink transmission. A recipient station receives a trigger frame. The trigger frame including at least one per user info field. Each of the at least one per user info field comprising at least a user identifier field identifying a STA to be allocated a resource unit, a resource unit allocation field for allocating a resource unit for the identified STA, and a spatial stream allocation field identifying a number of streams to be allocated for the identified STA. The recipient STA evaluating an order of the at least one per user info fields to determine a sequence of the allocated streams that matches the order of the at least one per user info fields. The recipient STA comparing the values from each of the resource unit allocation fields and grouping corresponding at least one per user info fields with matching values to identify members of a set STAs allocated to MU-MIMO. In some aspects, the spatial stream allocation field of the per user info fields comprises three bits.

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.

摘要： The present invention discloses methods and devices for communicating data in a Wireless Local Area Network (WLAN). An orthogonal frequency division multiplexing (OFDM) frame is communicated between an access point (AP) and a station (STA). The OFDM frame comprises a preamble section and a data payload section. The data payload section includes communication payload data and reference signal (RS) data pertaining to a wireless channel. The RS data comprises one of an orthogonal sequence-based reference signal (OSRS), a quasi-orthogonal sequence-based reference signal (QOSRS), and a tone interleaved long training field (TIL)-based RS.

摘要： Methods and apparatuses for supporting outside the context of a basic service set (OCB) concurrent with infrastructure-based communications, including cellular communications or basic service set (BSS) communications, are described. OCB service information is transmitted by an infrastructure unit in an infrastructure-based communication. The OCB service information include a service identifier and channel information for each available OCB service. The infrastructure unit may then communicate with a terminal unit over an OCB communication link, to provide an OCB service to the terminal unit. The OCB service information may be communicated in an OCB operation information element (IE) including a service hash field and an operating class and channel field.
