Relay transmission method and apparatus

摘要

A relay transmission method and apparatus are provided. The method includes: configuring a subframe of a Time Division Duplex relay frame for a subframe of relay link), where the configuring the subframe of the TDD relay frame for the subframe of relay link includes: configuring a downlink subframe of the TDD relay frame for a DL subframe of relay link, and/or configuring the DL subframe of the TDD relay frame for an uplink subframe of relay link, and/or configuring a UL subframe of the TDD relay frame for the UL subframe of relay link; and performing relay transmission according to the subframe of relay link. When data is transmitted, a subframe that can be used for relay link transmission is configured, data transmission performed by using relay link complies with inherent constraints of a TDD frame structure in the prior art.

1. A relay transmission method, comprising:
performing, by a base station, transmission between the base station and a relay node (RN) on a relay link, the relay link comprising an uplink (UL) relay link from the RN to the base station and a downlink (DL) relay link from the base station to the RN; wherein a time division duplex (TDD) frame includes ten subframes that are labeled as 0 to 9 from a first subframe to a tenth subframe, subframes 0, 4, 5 and 9 of the TDD frame being downlink subframes, subframes 2, 3, 7 and 8 of the TDD frame being uplink subframes, and subframes 1 and 6 of the TDD being special subframes; and wherein subframe 9 of the TDD frame is configured for the DL relay link and subframe 3 of the TDD frame is configured for the UL relay link; or, subframe 4 of the TDD frame is configured for the DL relay link and subframe 8 of the TDD frame is configured for the UL relay link; or, subframes 4 and 9 of the TDD frame are configured for the DL relay link and subframes 3 and 8 of the TDD frame are configured for the UL relay link.
