中继传输的方法及设备
摘要：
本发明的实施例公开了一种中继传输的方法及设备，所述方法包括：选取时分双工TDD中继帧中的子帧作为中继链路子帧，所述选取TDD中继帧中的子帧作为中继链路子帧包括：选取TDD中继帧中下行子帧用作下行中继链路子帧、和/或选取TDD中继帧中下行子帧用作上行中继链路子帧，和/或选取TDD中继帧中上行子帧用作上行中继链路子帧；根据所述中继链路子帧进行中继传输。本发明实施例中，在进行数据传输时，选取了可以用于中继链路传输的子帧，在使用中继链路进行数据传输时符合现有技术中TDD帧结构固有约束，而且对使用TDD中继帧的系统进行覆盖扩展，使得吞吐量增强。
摘要（英）：

The embodiment of the invention discloses a relay transmission method and a relay transmission device. The method comprises the following steps: selecting a subframe in a time division duplex (TDD) relay frame as a relay link subframe, wherein the step of selecting the subframe in the TDD relay frame as the relay link subframe comprises the following steps of selecting a downlink subframe in the TDD relay frame as a downlink relay link subframe, and/or selecting the downlink subframe in the TDD relay frame as an uplink relay link subframe, and/or selecting an uplink subframe in the TDD relay frame as the uplink relay link subframe; and carrying out relay transmission according to the relay link subframe. In the embodiment of the invention, in the process of data transmission, the subframe which can be used for relay link transmission is selected, when a relay link is used for carrying out data transmission, the intrinsic constraint of the TDD frame structure in the prior art is met, and a system using the TDD relay frame is covered and expanded, thereby enhancing the throughput.
