Abstract

The present invention provides a method and device for determining the interference intensity in a cell system. The method includes: screening out one or more first measurements that one or more terminals report that the target cell is a neighboring cell at a preset time point After reporting, according to the reference signal received power of the target cell and the transmit power headroom of the terminal in the first measurement report, obtain the interference intensity of each terminal as an interference source reaching the target cell, and obtain the one or more Interference strength generated by the uplink signal of the terminal to the target cell. In this way, by calculating the interference intensity in the cell system, the present invention can not only obtain the average value of PRB-level interference noise, but also obtain the interference intensity on the entire physical uplink shared channel PUSCH, and can reflect the interference situation of multiple adjacent cell terminals on the serving cell , the data is more comprehensive, and the uplink interference situation can be better analyzed.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a method and device for determining interference intensity in a cell system. Background technique [0002] The LTE (Long Term Evolution, long-term evolution) system adopts OFDMA (Orthogonal Frequency Division Multiple Access) multiple access mode in the downlink, and SC-FDMA (Single-carrier Frequency-Division Multiple Access, single-carrier frequency-division multiple access) in the uplink. Division multiple access) access mode. Due to the inherent characteristics of OFDMA / SC-FDMA itself, that is, the PRBs (Physical Resource Blocks) used by all UEs (User Equipment, user equipment) in a cell are orthogonal to each other in the frequency domain, so the intra-cell interference very small. However, since the frequency reuse factor of LTE is 1, that is, all cells are using the entire system frequency band at the same time, the interference in the LTE system ca...
