Abstract
The present invention provides an authorized shared access (ASA) assisted interference coordination method in a heterogeneous time-division duplexing (TDD) relay network. In a TDD relay system architecture, an ASA controller assists a secondary system to perform an interference coordination mechanism by adjusting a time slot structure configuration and synchronization information, and a mobility management entity (MME) obtains a time slot configuration and the synchronization information of a primary system through ASA, and selects, according to relevant information of a relay node inside a management range, an optimal time slot configuration and a working mode for the relay node.
