Title: Method and apparatus for avoiding collision in medium access of wlan
Inventor: KWON CHANG YEUL
IPC: H04W74/00
Filed: 2006-04-10
Abstract: A method and an apparatus for preventing a collision for medium access in a wireless LAN are provided to use the optimum collision prevention method according to the state of a wireless LAN by adaptively determining a collision prevention method according to the throughput of each station in the wireless LAN. If association request frames are received from stations, an AP(Access Point) judges the throughput of each of the stations belonging to a BSS(Basic Service Set), based on the HT(High Throughput) capabilities Info field of each of the received association request frames(110,120). As a result, if it is judged that HT stations and legacy stations exist together in the BSS or HT stations using their respective channel bandwidths exist together in the BSS, the AP judges whether every HT station supports an EPP(Extended Phy Protection) mechanism(130). If every HT station supports the EPP mechanism, the AP determines that HT-formatted data frames to be used in the BSS should contain EPP information, and notifies every station of this policy(140).
