LINK ADAPTATION METHOD IN A WIRELESS LOCAL AREA NETWORK (LAN) SYSTEM AND AN APPARATUS THEREOF, CAPABLE OF TRANSMITTING ADDITIONAL INFORMATION ACCORDING TO MODULATION AND CODING SCHEME (MCS) FEEDBACK (MFB) AND MFB TYPE TO AN MFB REQUESTER EFFICIENTLY

摘要

PURPOSE: A link adaptation method in a wireless LAN network system and an apparatus thereof are provided to enable an MFB requester to transmit control information required in a link adaptation procedure to an MCS feedback response person.;CONSTITUTION: A processor (72) receives physical layer convergence procedure (PLCP) protocol data unit (PPDU) from an access point (AP). The processor estimates MFB on the basis of the PPDU. The processor transmits feedback information including an MFB field and an MFB type field to the AP. The MFB field includes the MFB. The MFB type field indicates whether the MFB is a response to MFB request (MRQ) of the AP or not.;COPYRIGHT KIPO 2013;[Reference numerals] (72) Processor; (74) Memory; (76) Transceiver
