    摘要： A method for reporting channel information in a wireless local area network system is provided. The method includes receiving a data block for requesting a modulation and coding scheme (MCS) feedback from a requesting station, the data block including a data field and a stream indicator indicating a number of at least one spatial stream in the data field; determining, the MCS feedback based on the data block; and, transmitting the MCS feedback to the requesting station, the MCS feedback including a recommended MCS and a recommended stream indicator indicating a number of at least one recommended spatial stream. The number of the at least one recommended spatial stream in the MCS feedback is equal or less than the number of the at least one spatial stream in the data block.

    摘要： A channel sounding method in a wireless local area network (WLAN) system is provided. The method, performed by a transmitter, includes transmitting a null data packet announcement (NDPA) frame to a receiver to initiate a channel sounding procedure; transmitting a null data packet (NDP) to the receiver and receiving a feedback frame. The feedback frame includes a plurality of segment frames and a channel feedback report. The channel feedback report is split into a plurality of feedback segments. Each of the plurality of feedback segments is respectively included in each of the plurality of segment frames. The each of the plurality of segment frames includes a first-segment subfield indicating whether the each of the plurality of feedback segment included is a first segment and a remaining-segment subfield indicating the number of remaining feedback segments.

    摘要： A method of dynamic frequency selection by an access point (AP) in a basic service set (BSS) in a wireless local area network is provided. The access point configured to communicate over a primary subchannel and a secondary subchannel. The method includes: transmitting a frame including a quiet element and a quiet channel element; and performing channel measurements in the quiet interval. The quiet element defines an quiet interval during which no transmission occurs, the quiet channel element indicates that the secondary subchannel is to be quieted during the quiet interval, and the quiet channel element indicates a condition under which the primary subchannel may be used during the quiet interval.
