A method for preventing a relay node from missing a transmission from an access node. The method includes, when a ten millisecond periodicity is used for Multicast/Broadcast Single Frequency Network (MBSFN) subframes, setting a time between an uplink grant from the access node to the relay node and an acknowledgement/negative-acknowledgement message (ACK/NACK) from the access node to the relay node equal to ten milliseconds. The method further includes, when a forty millisecond periodicity is used for MBSFN subframes, the access node sending the relay node an asynchronous grant for an uplink retransmission when a data packet is missed, and when the relay node receives the grant for the uplink retransmission, the relay node retransmitting the missed data packet. |
