Embodiment Construction
[0043] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and examples.
[0044] In the embodiment of the present invention, by setting the minimum received code power level Qrxpwrmin (minus receive power) and SIRtarget in the UE in advance and setting a smaller Minimum_DL_Power in the Node B, three factors for controlling the downlink transmission power are comprehensively considered: Qrxpwrmin, SIRtarget and Minimum_DL_Power to reduce the downlink transmission power of the base station and reduce the call drop rate of the user equipment.
[0045] figure 2 It is a schematic flowchart of a method for UE controlling Node B downlink transmission power in the present invention. see figure 2 , the process includes:
[0046] Step 201, UE compares the acquired code power level Qrxpwr with the set minimum received code power le...
