    • A method and an apparatus for transmitting data in a wireless communication system are provided. A machine-to-machine (M2M) apparatus in a deregistration with context retention (DCR) mode generates an uplink (UL) data having a size which is smaller than 140 bytes, transmits a ranging request message (AAI-RNG-REQ) including the UL data to a base station, and receives from the base station a ranging response message (AAI-RNG-RSP) as a response to the ranging request message. The ranging request message comprises a ranging purpose indication field for indicating a location update for transmitting the UL data in the DCR mode. Also, the ranging response message comprises a location update response field for indicating a location update success in transmitting the UL data as a response to the ranging purpose indication field.
    • 提供了一种用于在无线通信系统中发送数据的方法和装置。 在具有上下文保持(DCR)模式的注销中的机器对机器(M2M)装置产生尺寸小于140字节的上行链路(UL)数据,发送包括以下内容的测距请求消息(AAI-RNG-REQ) 将UL数据发送到基站,并从基站接收作为对测距请求消息的响应的测距响应消息(AAI-RNG-RSP)。 测距请求消息包括用于指示用于在DCR模式中发送UL数据的位置更新的测距目的指示字段。 此外,测距响应消息包括位置更新响应字段,用于指示在作为对测距目的指示字段的响应的发送UL数据中的位置更新成功。

    • Provided is a method for performing coordinated communications by a relay station. The method comprises the following steps: receiving a signal from a terminal; measuring channel state information which indicates the state of the channel that receives the signal; comparing the channel state information and a preset threshold value to determine whether to decode the received signal; and, if the received signal is determined to be decoded, decoding the received signal to remove noise, encoding and forwarding the encoded signal to a base station (decode and forward: DAF), and, if the received signal is not determined to be decoded, amplifying the received signal, and forwarding the amplified signal to the base station (amplify and forward: AAF). The channel state information is at least one of frame error rate (FER), bit error rate (BER), signal to noise ratio (SNR) and signal to interference plus noise ratio (SINR). According to the present invention, time delay required for channel decoding can be reduced in hybrid DAF coordinated communications, data transmission and resource usage can be performed in a more efficient manner in coordinated communications using multiple terminals, and unnecessary consumption of power can be reduced.
    • 提供一种用于执行中继站的协调通信的方法。 该方法包括以下步骤:从终端接收信号; 测量指示接收信号的信道的状态的信道状态信息; 比较信道状态信息和预设阈值以确定是否对接收到的信号进行解码; 并且如果确定接收到的信号被解码,则对接收到的信号进行解码以去除噪声,编码并将编码信号转发到基站(解码和转发:DAF),并且如果接收信号未被确定为被解码 放大接收到的信号,并将放大的信号转发到基站(放大和转发:AAF)。 信道状态信息是帧错误率(FER),误码率(BER),信噪比(SNR)和信噪比加噪声比(SINR)中的至少一个。 根据本发明,可以在混合DAF协调通信中减少信道解码所需的时间延迟,可以以更有效的方式在使用多个终端的协调通信中执行数据传输和资源使用,并且可以减少不必要的功率消耗。
