摘要： A method for wireless communication comprises a donor enhanced Node B (eNB) transmitting system information for a subframe structure to a relay node (RN), which information comprises radio resource configuration and/or timing information for uplink backhaul transmission. The RN uses an automatic method to select the Round Trip Time (RTT) value for the Hybrid Automatic Repeat request (HARQ) on the uplink backhaul (Un) relay link. The RTT value is implicitly determined according to the Un (backhaul) subframe or MBSFN subframe configuration periodicity. The RTT option is signaled by the Un subframe configuration period of the MBSFN Un downlink signals.
