    • A method for supporting P2P communication between two user equipments in TDD CDMA systems, performed by user equipment, comprising: receiving signals transferred via the downlink control channel from network system; acquiring the timeslot allocation information and the spreading code allocation information of other active user equipments allocated in the specific downlink timeslot associated with the direct link used by said user equipments, according to the received signals; and synchronizing the P2P communication signals received by the user equipment and signals from network system, according to the acquired timeslot allocation information and spreading code allocation information, so as to reduce the interference caused by the downlink signals transmitted from network system to other user equipments during the P2P communication process.
    • 一种支持由用户设备执行的TDD CDMA系统中的两个用户设备之间的P2P通信的方法,包括:经由所述下行链路控制信道从网络系统接收的信号; 根据接收到的信号,获取在与所述用户设备使用的直接链路相关联的特定下行链路时隙中分配的其他活动用户设备的时隙分配信息和扩展码分配信息; 并根据所获取的时隙分配信息和扩展码分配信息,同步由用户设备接收的P2P通信信号和来自网络系统的信号,以便减少由网络系统向其他用户设备发送的下行链路信号所引起的干扰 P2P通信过程。
