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.
摘要翻译：一种无线通信系统中的终端位置估计方法，其中接入点（AP）向多个终端提供接入服务包括通过空间多路复用来定义AP周围的多个波束空间; 根据预定模式调度光束空间; 同时在至少一个梁空间中形成梁; 以及根据是否接收到响应于所形成的波束的响应消息来检测终端的存在和位置。因此，AP以预定的调度模式形成波束，并且通过向AP指示每个终端存在于相关的波束区域中，检测波束的每个终端登记其位置，因此每个终端的位置可以估计不使用复杂的DOA算法。

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.

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.
摘要翻译：提供了一种在无线LAN中以高速率发送数据的方法。如果发送到终端的数据发生，则无线接入点从具有等于或小于预定传输速率的传输速率的无线终端请求可靠节点信息。终端产生包含与终端通信的可靠节点和可靠节点与终端之间传输速率最大的信息相关联的帧，并将帧发送到接入点。接入点根据可靠节点与接入点之间的最大传输速率和可靠节点与终端之间的传输速率，从可靠节点中选择最佳中继节点，并确定在使用最优节点时是否存在中继增益。如果存在继电器增益，则接入点对终端执行中继传输; 否则，它直接传输到它。
