摘要： Provided is a coding/decoding apparatus for an orthogonal frequency division multiple access (OFDMA) communication system that takes multiple users into consideration and uses block coding/decoding scheme. In the apparatus, a mapper determines paths through which information of users will be provided, according to states of sub-channels allocated to the users. A coding/decoding unit parallel-processes the information of the users through the paths selectively connected by the mapper. The coding/decoding unit includes coders/decoders having performance lower than the maximum processing performance determined taking into account a size of a processing block and the number of sub-channels.

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 method for transmitting data at a high rate in a wireless LAN is provided. A wireless access point (100) requests reliable node information from a wireless terminal (120) having a transfer rate equal to or less than a predetermined transfer rate if data to be transmitted to the terminal occurs. The terminal (120) produces a frame containing information related to reliable nodes (100,110) 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 (100) 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.

摘要： A handoff method is provided in a communication network including a plurality of fixed nodes attached to a router connected to at least one external network, and at least one mobile node associated with a current fixed node. The method detects movement of a mobile node; prepares a handoff of the mobile node from a current fixed node to potential fixed nodes upon detecting movement of the mobile node; decides whether to handoff to one of the potential fixed nodes as a target fixed node; and performs the handoff from the current fixed node to the target fixed node. The handoff method enables the mobile station to quickly move its association from one access point to another by minimizing a probe delay which is a primary contributor to handoff delay.
