Abstract

The present invention relates to the field of communications technologies, and in particular, to an RLC data packet retransmission method and an eNodeB, so as to resolve a technical problem that a throughput of UE is relatively low because of a relatively large retransmission delay caused when a micro eNodeB performs a 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, that is, whether a delay is relatively small. If the HARQ combination gain can be obtained, the micro eNodeB retransmits the RLC data packet in a HARQ manner, so that the delay is relatively small, and impact on a throughput of UE is avoided as much as possible.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a method for retransmitting an RLC data packet and a base station. Background technique [0002] A Long Term Evolution (Long Term Evolution, LTE) system includes an evolved packet core network (Evolved Packet Core, EPC), an evolved base station (Evolved NodeB, eNodeB) and a user equipment (User Equipment, UE). The EPC is a part of the core network, including a Mobility Management Entity (MME) responsible for signaling processing and a Serving Gateway (SGW) responsible for data processing. The eNodeB and the EPC are connected through the S1 interface, the eNodeBs are connected through the X2 interface, and the eNodeB and the UE are connected through the Uu interface. [0003] The Evolved Universal Terrestrial Radio Access Network (Evolved Universal Terrestrial Radio Access Network, E-UTRAN) is composed of eNodeBs and is responsible for wireless-related functions. The E-UTR...
