TRANSMISSION METHOD OF RELAY LINK, BASE STATION AND RELAY SYSTEM

摘要

The present invention discloses a transmission method of relay link, a base station and a relay system. The method includes the following steps: obtaining the conditions of receiving the data transmitted by relay node RN; according to the receiving conditions, transmitting ACK/NACK feeding information to the RN, and transmitting uplink scheduling instruction to the RN, which indicates the RN to transmit data to the base station according to the uplink scheduling instruction. HARQ reliable transmission on the network using relay technology is realized by the embodiment of the present invention.
