摘要:
Provided are a method and apparatus which can reduce the possibility of collision with other frames when transmitting a broadcast/multicast frame in a wireless local area network (LAN) following a Distributed Coordination Function (DCF) rule, thereby ensuring reliable transmission. The wireless communication method for sending or receiving a predetermined frame through contention between an access point and one or more stations according to DCF is characterized in that the access point uses the shortest of interframe space (IFS) intervals for access to a wireless medium. Therefore, when wireless LAN STAs operate in a DCF mode, the possibility of collision during broadcast or multicast frame transmission can be reduced while adopting conventional CSMA/CA mechanism, thereby improving reliability in successful frame transmission.
