In another implementation manner, after adding the first base station to the E-DCH active set of the UE, the radio transceiver unit is further configured to receive first control signaling sent by a network; and receive an F-DPCH of the first base station according to an instruction of the first control signaling; or receive a downlink DPDCH sent by the first base station, where the downlink DPDCH is used to carry DCH data received by the UE from the first base station.
In another implementation manner, the radio transceiver unit is further configured to receive a downlink DPCCH of the first base station, where the downlink DPCCH is used by the first base station to send physical layer control signaling to the UE.
In another implementation manner, the first control signaling sent by the network includes second RRC signaling sent by the RNC; or first physical layer signaling sent by a second base station in the access network, where the second base station is in the E-DCH active set or a DCH active set of the UE.
In another implementation manner, before receiving the first control signaling sent by the network, the radio transceiver unit is further configured to measure common pilot channel quality of each cell; and send a measurement report to the RNC when measuring that common pilot channel quality of the first base station is greater than a preset first threshold, so that the RNC sends the second RRC signaling to the UE according to the measurement report, or so that the RNC instructs the second base station to send the first physical layer signaling to the UE.
