Abstract

A procedure for selecting the best path from among a direct link setup (DLS) path and an access point (AP) path is disclosed. A method for selecting the best path by a first wireless station from among the DLS path and the AP path includes: receiving a first message, e.g., a path switch request message, comprising measured quality information of a link constituting the DLS path and/or a link constituting the AP path from a second wireless station, a counterpart of the DLS path; and determining whether to switch a data transmission path or a data reception path between the DLS path and the AP path by using the received measured channel quality information. Although there is no explicit request from the counterpart of the DLS link, the path switch request message including the measured channel state information of the DLS link and the link of the AP path is transmitted, so the wireless stations using the DLS service can acquire the channel state information of the links frequently to transmit data by using a path of better channel state.
