Problems solved by technology

When the inter-cell interference fluctuates greatly at different times, even if the channel quality during uplink transmission is predicted based on the channel quality at the time of receiving SRS, the estimated SINR of the cell may still be inaccurate

Abstract

The invention discloses a method and device for processing inter-cell interference, a control device and a base station. The method comprises the steps of: managing a first cell by a first base station, obtaining resource scheduling information of neighbor cells of the first cell in a first time interval, and determining the level of the inter-cell interference of the first cell according to the obtained resource scheduling information; and measuring the inter-cell interference value of the first cell in a second time interval, using the interference level determined according to the resource scheduling information of the first time interval as an index, and storing the inter-cell interference value of the first cell in the second time interval. Based on an association relation between the stored interference level and the practical inter-cell interference value obtained by measurement, the first base station can rapidly and accurately predict the inter-cell interference value in the future by determining the interference level of the inter-cell interference, and the influences of the fluctuation of the inter-cell interference on the accuracy of SINR estimation are further reduced.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a method, equipment, control device and base station for dealing with inter-cell interference. Background technique [0002] In the Long Term Evolution (English: LongTermEvolution; abbreviation: LTE) system, during uplink scheduling, the user equipment sends a Sounding Reference Signal (English: Sounding Reference Signal; abbreviation: SRS) to the base station equipment, and the base station estimates the uplink channel quality according to the time when the SRS is received. Signal to Interference plus Noise Ratio (English: SignaltoInterferenceplusNoiseRatio; abbreviation: SINR) of the cell during uplink transmission, and at the scheduling time, resources for uplink transmission are scheduled for the user equipment, and the modulation and coding method used by the user equipment during uplink transmission is determined. [0003] Generally, when estimating t...
