METHOD FOR DIRECT LINK IN WIRELESS COMMUNICATION SYSTEM

摘要

A method for direct link in wireless communication system is provided, which is applied in a base station with functions for broadcast and time division duplex (TDD), the method comprising the following steps: receiving connection request signalin gs including position information from a plurality of subscriber stations (SSs) with glob al positioning systems (GPSs); determining the SSs which can carry out the direct link, according to the connection request signalings; allocating time slots to each SS which can carry out direct link in the scheduling; calculating a relative distance between the two SSs according to the position information; determining an initial transmit power for the transmitting SS, and adjusting it many times; finally, adding the adjusted transmit power value a nd the time slot information allocated to the SSs in the scheduling into the broadcast messag e.
