Embodiment 1
[0138] The base station counts the signal power of edge users in SRS and PUCCH channels in units of one hour, and the distinction between edge users and center users is obtained through the center / edge user distinction module of the algorithm.
[0139] Among them, there are N records about SRS, and there are M records about PUCCH. These records are sorted and processed to obtain the distribution curve CDF of RS and PUCCH respectively. RS and CDF pucch .
[0140] Take the value at 5% of the distribution curve as the signal power of SRS and PUCCH at the cell edge, respectively, P RS and P pucch .
[0141] Judging the difference between the two ΔP=P SRS -P pucch ,Find It is determined that the coverage of the PUCCH is basically equivalent to the coverage of the SRS.

Abstract
The invention relates to a wireless communication technology, in particular to a method for adjusting a power parameter value and equipment thereof, aiming at solving the problem that the coverage area of each signal path is inconsistent easily caused by the inaccurate manual adjustment of the power parameter value in the prior art. The method of the embodiment comprises the following steps of: ensuring a difference value between SRS power and physical uplink signal path power, wherein the SRS power is signal power when a terminal transmits SRS, and the physical uplink signal path power is signal power when the terminal receives transmission data and control information through a physical uplink signal path; and adjusting an SRS power parameter value or a physical uplink signal path powerparameter value when the difference value is within a previously-set adjustment range. The embodiment of the method can lead the power difference value between the adjusted powder of a reference signal for detecting and the power of the physical uplink signal path to be smaller, and reduces the condition that the coverage area of each signal path is inconsistent.
Description
technical field [0001] The invention relates to wireless communication technology, in particular to a method and equipment for adjusting power parameter values. Background technique [0002] SRS (Sounding Reference Signal) is a known signal provided by the transmitting end to the receiving end for channel detection. The reference signal for sounding is mainly used for the following two purposes: [0003] 1. Uplink channelestimation, used for coherent detection and demodulation at the eNodeB (evolved base station) side; [0004] 2. Uplink channelquality measurement, that is, CQI (Channel Quality Indicator, channel quality indicator) measurement. [0005] For a TDD (Time Division Duplex, Time Division Duplex) system, since the uplink and downlink are symmetrical, the uplink reference signal can also be used to acquire downlink channel quality information. [0006] PUSCH (Physical Uplink Shared Channel, Physical Uplink Shared Channel) is used to carry data from the transpo...
