Patent ID: 10419167

Abstract:
The present invention relates to the field of communications technologies, and in particular, to a Radio Link Control (RLC) data packet retransmission method and an eNodeB, so as to resolve a technical problem that a throughput of user equipment (UE) is relatively low because of a relatively large retransmission delay caused when a micro eNodeB performs a hybrid automatic repeat request (HARQ) on a data packet. In embodiments of the present invention, if feedback information that is received by a macro eNodeB for an RLC data packet transmitted by a micro eNodeB is a NACK, the macro eNodeB determines whether a HARQ combination gain can be obtained by performing a HARQ on the RLC data packet by the micro eNodeB. If the HARQ combination gain can be obtained, the micro eNodeB retransmits the RLC data packet in a HARQ manner, so that the throughput of UE can be improved.
