Embodiment Construction

[0035] The present invention provides a method for power control of user equipment. The core of the present invention is: UE gradually increases the transmit power of uplink DPCCH in a step-by-step manner according to the detection result of the downlink control channel of the base station.

[0036] Describe the present invention in detail below in conjunction with accompanying drawing, the processing flow of the embodiment of the method of the present invention is as follows figure 1 shown, including the following steps:

[0037] Step 1-1: The UE maintains the CELL_DCH state, and when the UE has new data to send, it resumes DPCCH transmission according to the set power.

[0038] When the UE is idle without data transmission, the UE also maintains the CELL_DCH state, but does not transmit the uplink DPCCH.

[0039] When the UE in the CELL_DCH state has new data to send, the UE starts the power control process of the DPCCH recovery period. The UE first sets a number of attemp...

Abstract

The invention discloses a power control method of user facility, which comprises the following steps: recoverying and carrying out ascending DPCCH (private physics control channel) launching; checking descending control channel of base station; adjusting the ascending DPCCH sending power according to the result of descending control channel. The invention can control UE sending power when the DPCCH recovers, which improves the system capacitance.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method for power control of user equipment. Background technique [0002] At the 29th meeting of 3GPP RAN (Third Generation Partnership Project Radio Access Network), a permanent online (Continuous connectivity for packet data users) work item was approved. The main goal of this work item is: to improve packet service the number of online users. [0003] In the wireless access network, the service flow model of some services is to send data intermittently, and the number of data interruptions may be very large during a service process. For example, in the web browsing service, generally, web page downloading (with data transmission) and web page browsing (without data transmission) are performed alternately. There are also some businesses that require sporadic data transmission for a long time. [0004] In the above services, if the same state is maintained when there is no...
