摘要:
A method for preventing a first network node from missing a transmission from a second network 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 second network node to the first network node and an acknowledgement/negative-acknowledgement message (ACK/NACK) from the second network node to the first network node equal to ten milliseconds. The method further includes, when a forty millisecond periodicity is used for MBSFN subframes, the second network node sending the first network node an asynchronous grant for an uplink retransmission when a data packet is missed, and when the first network node receives the grant for the uplink retransmission, the first network node retransmitting the missed data packet.
