    • A method for modifying a synchronous non-adaptive retransmission scheme to solve the limitation of the synchronous non-adaptive retransmission scheme is disclosed. A method for indicating not only the new data transmission but also the retransmission using a data scheduling message is disclosed. A method for determining whether there is an error in the ACK signal transmitted from a data reception end using another message to be received later is disclosed. The retransmission method for a multi-carrier system includes: receiving a grant message including scheduling information for transmitting uplink data wherein a retransmission scheme for the uplink data is predetermined by a first retransmission scheduling, transmitting the uplink data according to the scheduling information and retransmitting the uplink data according to second retransmission scheduling by receiving the second retransmission scheduling information associated with the uplink data with retransmission request.

    • A method for efficiently transmitting and receiving control information through a Physical Downlink Control Channel (PDCCH) is provided. When a User Equipment (UE) receives control information through a PDCCH, the received control information is set to be decoded in units of search spaces, each having a specific start position in the specific subframe. Here, a modulo operation according to a predetermined first constant value (D) is performed on an input value to calculate a first result value, and a modulo operation according to a predetermined first variable value (C) corresponding to the number of candidate start positions that can be used as the specific start position is performed on the calculated first result value to calculate a second result value and an index position corresponding to the second result value is used as the specific start position. Transmitting control information in this manner enables a plurality of UEs to efficiently receive PDCCHs without collisions.
    • 提供了一种通过物理下行链路控制信道(PDCCH)高效地发送和接收控制信息的方法。 当用户设备(UE)通过PDCCH接收到控制信息时,所接收的控制信息被设置为以搜索空间为单位进行解码,每个搜索空间在特定子帧中具有特定的开始位置。 这里,对输入值执行根据预定的第一常数值(D)的模运算以计算第一结果值,并且根据与候选开始位置的数量相对应的预定的第一可变值(C)进行模运算 对计算出的第一结果值执行可用作特定开始位置的计算第二结果值,并将与第二结果值对应的索引位置用作特定开始位置。 以这种方式发送控制信息使得多个UE能够有效地接收PDCCH而不发生冲突。
