    • 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 signalings including position information from a plurality of subscriber stations (SSs) with global 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 and the time slot information allocated to the SSs in the scheduling into the broadcast message.
    • 提供一种用于无线通信系统中的直接链路的方法,其应用于具有广播和时分双工(TDD)功能的基站,该方法包括以下步骤:从多个订户接收包括位置信息的连接请求信号 具有全球定位系统(GPS)的车站(SS); 根据连接请求信号确定可以执行直接链路的SS; 向可以在调度中执行直接链路的每个SS分配时隙; 根据位置信息计算两个SS之间的相对距离; 确定发射SS的初始发射功率,并进行多次调整; 最后,将调度后的发送功率值和分配给调度中的SS的时隙信息添加到广播消息中。
