MEDIUM ACCESS APPARATUS AND METHOD FOR PREVENTING A PLURALITY OF STATIONS IN A WIRELESS LOCAL AREA NETWORK FROM COLLIDING WITH ONE ANOTHER |
摘要 |
<p>A method and apparatus for preventing a plurality of stations in a wireless local area network (WLAN) where a plurality of high throughput (HT) stations and a plurality of 802.11 legacy stations coexist from colliding are provided. The method includes generating a data frame having an HT format by inserting information indicating that a medium will be unavailable until the reception of an acknowledgement (ACK) frame is concluded into a physical layer (PHY) header having a format that can be interpreted by both the HT stations and the legacy stations; transmitting the data frame; and transmitting a reset frame which resets network allocation vectors (NAVs) of a plurality of stations which have heard the data frame, and has a format that can be interpreted by both the HT stations and the legacy stations. The apparatus includes a data frame generation unit; a reset frame generation unit; and a transmission unit.</p> |
