摘要： In a wireless communication system a control channel is required in order to use limited resources effectively. However, the control channel resource is part of the system overhead, and thus reduces the data channel resource used for data transmission. In the long term evolution (LTE) system based on OFDM, one sub frame the consists of fourteen OFDM symbols wherein a maximum of three OFDM symbols are used for the control channel resource and remaining eleven OFDM symbols are used for the data channel resource. Therefore, the quantity of energy that can be transmitted for the control channel resource is extremely limited compared to the data channel resource. For this reason, the coverage of the control channel becomes less than that &; of the data channel, and even if a user can successfully receive the data channel, reception failure of a control channel sometimes˜results in failure of data recovery. In the present invention, in order to expand the coverage of the control channel to at least the coverage of the data channel, the time resource of the transmission resource wherein the control channel is transmitted is expanded and allocated for sending and receiving the control channel. By way of methods for extending the time resource are provided a method wherein a plurality of sub frames are used to transmit one control channel, and a method wherein a part of a data channel is used for the control channel.

摘要翻译： 在无线通信系统中，为了有效地使用有限资源，需要控制信道。 然而，控制信道资源是系统开销的一部分，从而减少了用于数据传输的数据信道资源。 在基于OFDM的长期演进（LTE）系统中，一个子帧由十四个OFDM符号组成，其中最多三个OFDM符号用于控制信道资源，剩余的十一个OFDM符号用于数据信道资源。 因此，与数据信道资源相比，可以发送用于控制信道资源的能量的数量极其有限。 因此，控制通道的覆盖范围小于＆; 的数据通道，即使用户能够成功接收数据通道，控制通道的接收故障有时会导致数据恢复失败。 在本发明中，为了将控制信道的覆盖范围扩展至数据信道的覆盖范围，发送控制信道的发送资源的时间资源被扩展并分配用于发送和接收控制信道。 提供了一种用于扩展时间资源的方法，其中使用多个子帧来发送一个控制信道，以及一种方法，其中将数据信道的一部分用于控制信道。
