In this embodiment, the sending module 112 is further configured to send a receiving capability message to the RNC before the receiving module 111 receives the second instruction signaling sent by the RNC, where the receiving capability message is used to indicate that the first base station can receive an E-DCH service sent by the UE.
The base station according to this embodiment may be configured to execute the technical solution in the method embodiment shown in
According to the base station provided by this embodiment, when a first base station in an access network is not in an E-DCH active set of a UE, a sending module sends an E-HICH to the UE after a receiving module receives an E-DCH service sent by the UE, so that the sending module may continuously send an E-DCH service to the first base station when the UE learns, according to the E-HICH, that the first base station correctly received the E-DCH service sent by the UE. Therefore, uplink coverage of the first base station may be well utilized to improve a throughput rate and reliability of transmission at an edge area of a HetNet; further, uplink interference that is caused to the first base station when the UE, in area B shown in the figure, performs service transmission in a HetNet may be reduced.
