  • Patent number: 8619580
    Abstract: Provided is a method and apparatus for transmitting a packet in a wireless communication system. A method for transmitting a packet by a packet transmission apparatus in a wireless communication system includes determining whether the packet is a response packet, and transmitting the packet with a higher channel access opportunity than another packet transmission apparatus of the wireless communication system, if the packet is a response packet. Accordingly, it is possible to solve the problem that the total system performance degrades because a packet transmission apparatus fails to fully use its own transmission time by failing to rapidly receive a response packet even when packets remain to be transmitted in a wireless communication system using a contention-based channel access scheme.

  • Publication number: 20120163216
    Abstract: Disclosed is a media access control apparatus and method in a wireless local area network (LAN) system, which improves the performance of a wireless network by obtaining a transmission opportunity based on information on a station (STA), received from an access point (AP) in a contention-based distributed media access control system such as an IEEE 802.11 wireless LAN system. In the media access control apparatus and method, a station determines a contention window (CW) value based on information on other stations accessing a same access point and information on the idle state of a channel, so that an inefficient CW value is be set in a Distributed Coordination Function (DCF) used in the IEEE 802.11. Accordingly, it is possible to increase the processing speed of the station and to the efficiency of a wireless LAN network.
