TDDシステムバックホールリンク通信方法、デバイスおよびシステム

Japanese Patent JP5393875

B2

The present invention provides a method, device and system for backhaul link communication in a TDD system. Wherein, the method includes: a base station allocating an uplink subframe for uplink transmitting of the backhaul link and a downlink subframe for downlink transmitting of the backhaul link, and notifying subframe allocating information to a relay node; and the base station communicating with the relay node by the uplink subframe and the downlink subframe of the backhaul link. The solution allocates the uplink subframe and the downlink subframe of the backhaul link according to certain rules, performs related HARQ operation based on the allocated uplink subframe and downlink subframe, and ensures the availability and reliability of backhaul link communication.
