Abstract

The invention discloses a method and apparatus for reducing uplink interference to reduce the complexity of uplink interference and error adjusting probability, and ensure effect of uplink interference reduction. The method includes the steps of a base station providing A3 measurement related parameters for each UE with the management scope of the base station, determining current flow losing difference of each UE based on the A3 measurement results reported by each UE, and determining the uplink receiving power upper limit for each UE to corresponding service cell based on the current flow losing difference of each UE and the uplink receiving interference power upper limit from each UE to an adjacent area corresponding to current flow losing difference. The emission power of the UE, of which the uplink receiving power to corresponding service cell exceeds the corresponding uplink receiving power upper limit, is not increased. In this way, a target UE is selected based on A3 measurement results reported by each UE, and the accuracy of the target UE selected is high. The error adjusting probability is reduced, and the effect of uplink interference reduction is ensured.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, in particular to a method and device for alleviating uplink interference. Background technique [0002] In the Long Term Evolution (LTE), as the number of user equipment (User Equipment, UE) continues to increase, the uplink interference problem of the LTE system is becoming more and more serious, especially for UEs between overlapping coverage cells, to The higher the received power of the own serving cell, the greater the interference to neighboring cells. In order to reduce system interference and improve communication quality, in the prior art, the method of "open-loop power control plus closed-loop adjustment" is usually adopted, and "slow power control" is performed for each UE separately. Among them, the implementation scheme of the above-mentioned closed-loop adjustment mainly includes : Perform power control based on uplink received power, perform power control base...
