- the wireless transceiver unit 311 when the UE receives DCH data from the access network, the wireless transceiver unit 311 is further configured to send an F-DPCH to the UE, where the F-DPCH is used by the UE.
- the base station performs uplink transmission power control on the UE.
- the wireless transceiver unit 311 when the UE receives DCH data from the access network, the wireless transceiver unit 311 is further configured to disable the function of sending a downlink DPCCH to the UE.
- the radio transceiver unit 311 is further configured to receive the second RRC signaling sent by the RNC.
- the processing unit 312 is further configured to: When the UE does not receive DCH data from the access network, send an F-DPCH to the UE according to the indication of the second RRC signaling; when the UE receives DCH data from the access network And sending, according to the indication of the second RRC signaling, a downlink DPDCH to the UE.
- the wireless transceiver unit 311 is further configured to: when the UE does not receive DCH data from the access network, the received first network signaling includes an F-DPCH configuration.
- the wireless transceiver unit 311 when the UE receives DCH data from the access network, the wireless transceiver unit 311 is further configured to send a downlink DPCCH to the UE.
- each device whether UE, RNC or base station, can be implemented by hardware, such as an integrated circuit or a PCB.
- Any of the transceiver units can be a radio unit, such as a transceiver, and any of the processing units can be a processor, including but not limited to a baseband processor or a central processing unit.
- the UE When transmitting E-DCH data, the UE is still receiving DCH data (generally voice or high-layer control signaling).
- the DCH data is carried on the downlink DPCH channel, and the DPCH channel can be divided into two parts, DPDCH and DPCCH, and DPDCH bearer.
- the DPCCH For DCH data, the DPCCH carries the physical control information required to receive the DCH data, such as the transmission power control TPCXTransmit Power Control, the pilot pilot, and the transport format combination indication TFCI (Transmit)
- the UE When the UE sends the E-DCH data, if the DCH data is not received, in the prior art, the UE does not need (and does not need to) receive the DPCH, but needs to receive the F-DPCH, and the F-DPCH carries the transmission power control.
- the TPC is used to perform uplink power control on the UE.
- the UE may add the LPN (low power node, ie, the micro base station, corresponding to the first base station mentioned in FIG. 26 to FIG. 31 before) to the E-DCH activation in the B area shown in FIG. 1 .
- the LPN can receive the E-DCH data sent by the UE, but the downlink quality of the LPN is relatively poor.
- the UE should The F-DPCH is received from the LPN.
- the downlink of the LPN is relatively poor.
- the UE may not receive the F-DPCH of the LPN, and the LPN may not send the F-DPCH, thereby saving power consumption of the LPN, saving power consumption of the UE, and avoiding The high error rate caused by the poor downlink transmission quality of the LPN affects the uplink transmission of the UE.
- the UE should also receive the DCH from the LPN, that is, simultaneously receive the DPCCH and the DPDCH, but due to the poor downlink quality of the LPN, the DPCCH
- the error rate of the DPDCH is relatively high.
- the UE does not receive the DPDCH from the LPN, but receives some control information that is carried on the DPCCH.
- the UE does not receive the DPCCH, and further reduces the power consumption of the downlink channel received by the UE. If the LPN needs to perform uplink power control on the UE, the UE may receive the F-DPCH sent by the LPN.
- the transmit power overhead and the receive power overhead of the F-DPCH are smaller than the DPCCH, and the UE decodes the TPC on the F-DPCH to adjust. Send your own uplink power.
- the UE moves from the B area to the C, the downlink quality of the LPN gradually improves, and the RNC control UE can return to the soft handover procedure of the prior art.
- the network indicates that the UE starts to receive the DPCH sent by the LPN. If the UE does not receive the DCH data from the network, the embodiment indicates that the UE receives the F-DPCH sent by the LPN through network signaling. .
- the embodiment of the present invention enables the UE to not receive the F-DPCH or the DPCCH or the DPDCH when needed, for example, the UE can be flexibly shut down when the downlink quality of a base station to the UE is degraded. Partially receiving the function, or turning off the corresponding sending function to the UE, reducing the transmission power loss of the low-quality wireless link sent by the base station, and reducing the receiving power loss of the low-quality wireless link received by the UE, reducing the link quality degradation and causing network communication
- the base station and the RNC can use the closed wireless link to serve other UEs, increasing the downlink capacity of the network.
- the disclosed apparatus and method may be implemented in other manners.
- the device embodiments described above are merely illustrative.
- the division of the unit is only a logical function division.
- there may be another division manner for example, multiple units or components may be combined or Can be integrated into another system, or Some features can be ignored or not executed.
- the mutual coupling or direct coupling or communication connection shown or discussed may be an indirect coupling or communication connection through some interface, device or unit, and may be in an electrical, mechanical or other form.
- the units described as separate components may or may not be physically separated, and the components displayed as units may or may not be physical units, that is, may be located in one place, or may be distributed to multiple network units. Some or all of the units may be selected according to actual needs to achieve the objectives of the solution of the embodiment.
- each functional unit in each embodiment of the present invention may be integrated into one processing unit, or each unit may exist physically separately, or two or more units may be integrated into one unit.
