Title:
METHOD AND APPARATUS FOR DETERMINING MODULATION AND CODING SCHEME FEEDBACK IN WIRELESS LOCAL AREA NETWORK SYSTEM
Document Type and Number:
WIPO Patent Application WO/2012/067393
Kind Code:
A1
Abstract:
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.
