    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： The present invention relates to a method of determining a Modulation and Coding Scheme (MCS) feedback in a Wireless Local Area Network (WLAN) system, including an MCS FeedBack (MFB) responder receiving a first frame, including a request message requesting to send the MFB, from an MFB requester and the MFB responder sending the MFB, including a recommended MCS value, to the MFB requester. The recommended MCS value is derived with reference to at least one of unsolicit type information indicative of a type of the MFB, transmit type information indicative of a transmission type of data, coding type information indicative of a coding scheme applied to the data, a group ID indicative of a group of target stations (STAs) to which the data will be transmitted, and MFB bandwidth information indicative of a bandwidth of a channel.
