摘要： A method and apparatus for reducing the power consumption of a wireless LAN device that operates in a wireless network are disclosed. The method for reducing the power consumption includes receiving a high throughput (HT) frame; judging whether the received HT frame is decodable; and if the received HT frame is not decodable, switching the wireless LAN device into a standby mode, and maintaining the device in the standby mode for a duration of the HT frame.

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.

摘要： A method and apparatus for guaranteeing fairness regarding access to a medium among 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 are provided. In the WLAN, information that allows a plurality of hearing legacy stations and a plurality of hearing HT stations which receive a data frame having an HT format transmitted by a transmitting HT station to fairly contend for use of a medium is transmitted as a frame having a format that can be interpreted by all the legacy HT stations. Therefore, the legacy stations can contend for a medium under the same conditions as the HT stations.

摘要： A data transmission method in a wireless LAN, an access point device and a station device are provided. The data transmission method for transmitting data from an access point on a wireless LAN includes allocating a sub-contention free period in which 802.11 based legacy stations and high throughput (HT) stations with multiple antennas obtain a channel use right through polling, and an HT contention period in which the HT stations can obtain a channel use right through contention. According to the method and devices, when there are no objects of polling in a contention free period, the period, in which the HT stations can obtain the channel use right though contention, is made to begin earlier such that without wasting the channel use period, the channel can be used flexibly.
