Abstract
In a P-MP fixed wireless access system using quasi-millimeter and millimeter wave bands, a relaying path is autonomously set up for subscriber stations without the need for additional provision of a repetition radio circuit using a costly MMIC. A subscriber station in the fixed wireless access system is provided with a repeating function for relaying signals between a different subscriber station and a base station, a buffer memory for temporarily storing signals to be communicated therebetween, and a table for registering information for identifying a relaying path between an own reference wireless station and a lower-level subscriber station for signal repetition. The base station is provided with a table in which, in order to perform signal communication with an arbitrary subscriber registered in the base station, routing information is registered for determining whether or not to set up a relaying path via a different subscriber station registered in the base station.
