    摘要： A method of re-transmitting a packet of an access point (AP) in a polling-based Wireless Local Area Network (WLAN) includes: scheduling a super frame to form a first period of providing a polling message to arbitrary stations at the AP and allowing only stations receiving the polling message to get access to a medium without contention, and to form a second period of allowing the stations to get access to the medium through contention; transmitting packets stored in a first transmission queue to the corresponding stations during the first period of the super frame; and enqueuing a packet whose transmission results in failure during a first portion of a second transmission queue to re-transmit the packet whose transmission has resulted in failure during the second period upon a determination that at least one of the packets transmitted to the stations has resulted in a failure to be transmitted.

    摘要： A terminal location estimation method in a wireless communication system in which an access point (AP) provides an access service to a plurality of terminals includes defining a plurality of beam spaces around the AP through space multiplexing; scheduling the beam spaces according to a predetermined pattern; simultaneously forming a beam in at least one beam space; and detecting the existence and location of a terminal according to whether a response message in response to the formed beam is received. Accordingly, an AP forms beams in a predetermined scheduling pattern, and each of the terminals detecting the beams registers its location by informing the AP that each of the terminals exists in a relevant beam area, and thus, a location of each of the terminals can be estimated without using a complex DOA algorithm.

    摘要： A method for transmitting data at a high rate in a wireless LAN is provided. A wireless access point requests reliable node information from a wireless terminal having a transfer rate equal to or less than a predetermined transfer rate if data to be transmitted to the terminal occurs. The terminal produces a frame containing information related to reliable nodes that can communicate with the terminal and information of greatest transfer rates between the reliable nodes and the terminal, and transmits the frame to the access point. The access point selects an optimal relay node from the reliable nodes, based on the greatest transfer rates between the reliable nodes and the access point and transfer rates between the reliable nodes and the terminal, and determines if a relay gain exists when using the optimal node. If the relay gain exists, the access point performs relay transmission to the terminal; otherwise, it performs direct transmission to it.
