Relay transmission method and network node

摘要

A relay transmission method and a network node are disclosed. The method includes: receiving configuration information about a relay link subframe, the relay link subframe is configured in subframes in a period equivalent to an integer multiple of one frame, where the relay link subframe takes on a specific HARQ timeline; and performing relay link transmission according to the relay link subframe. The relay transmission method put forward herein meets various constraint conditions of the LTE FDD system in the relay transmission performed according to the selected relay link subframe, and is backward-compatible with the UE in the existing LTE system.

1. A relay transmission method, comprising:
receiving, by a relay node, configuration information about a relay link subframe, wherein the relay link subframe is configured according to at least one basic pattern periodically in a period equivalent to four frames, each frame includes 10 subframes, wherein the basic pattern includes downlink (DL) subframes and uplink (UL) subframes, and wherein an interval between the UL subframes is one of 8 ms or 16 ms and a interval between the DL subframes is one of 8 ms or 16 ms; and performing, by the relay node, relay link transmission on the relay link subframe, wherein the maximum number of hybrid automatic repeat request (HARQ) processes on a relay link is equal to the number of basic patterns in the period equivalent to four frames, wherein a subframe number of a UL subframe included in the basic pattern=(a subframe number of a DL subframe included in the basic pattern+4) mod 40.
