    • A method for processing NDI in a random access procedure and a method for transmitting and receiving a signal using the same are disclosed. The method for transmitting an uplink signal from a user equipment (UE) to a base station comprises receiving a first uplink (UL) grant signal through a message identified by a temporary cell identifier (Temporary C-RNTI) from a base station, the first uplink grant signal including a new data indicator (NDI) toggled if the base station indicates new transmission; receiving a second uplink grant signal through a downlink control channel identified by a cell identifier (C-RNTI) from the base station, the second uplink grant signal including a new data indicator (NDI) with a predetermined value; and determining uplink signal retransmission of the user equipment depending on whether the NDI of the second uplink grant signal has been toggled, wherein the UE ignores the NDI received using the temporary cell identifier.
    • 公开了一种在随机接入过程中处理NDI的方法以及使用其进行发送和接收信号的方法。 用于从用户设备(UE)向基站发送上行链路信号的方法包括:从基站通过由临时小区标识符(Temporary C-RNTI)标识的消息来接收第一上行链路(UL)准许信号,第一 上行链路许可信号包括如果基站指示新的传输则切换的新数据指示符(NDI); 通过由所述基站由小区标识符(C-RNTI)标识的下行链路控制信道接收第二上行链路许可信号,所述第二上行链路许可信号包括具有预定值的新的数据指示符(NDI); 以及根据所述第二上行链路许可信号的NDI是否被切换来确定所述用户设备的上行链路信号重传,其中,所述UE忽略使用所述临时小区标识符接收到的所述NDI。
