Embodiment Construction

[0042] Considering the low accuracy of in-band interference positioning and inaccurate interference detection in the related art, the present invention proposes to determine the probability that the base station will cause interference to occupied resources according to the interference element information (including measurement information and configuration information, etc.), and then determine the interference The interference contribution coefficient of the base station that causes interference when it occurs, so that the position where the interference may occur can be determined based on the actual measurement data before the interference occurs, and the interference can be accurately located based on the position information, thereby avoiding the hysteresis of in-band interference detection. In addition, the accuracy of interference discovery and the accuracy of interference location can be improved.

Abstract

The invention discloses a method and a device for positioning in-band interference. The method comprises the following steps of: acquiring interference element information; determining all probable interference scenes and the probability of each interference scene in all the interference scenes according to the interference element information; determining an interference index of a base station involved by each interference scene; and determining the position of the base station which generates interference and the position of the interference according to the interference element information. By the method and the device, the interference can be positioned before the interference takes place, so the problem of delay of the positioning of the current interference is effectively solved; the interference can be accurately positioned on the basis of positional information; and the precision of discovering the interference and the accuracy of positioning the interference can be improved.

Description

technical field [0001] The present invention relates to the communication field, in particular to a positioning method and device for in-band interference. Background technique [0002] Frequency and code resource planning is the basis of network quality. However, with the development and construction of cities, the wireless communication environment becomes more and more complex and changeable, resulting in changes in the coverage of wireless base stations. Therefore, the planning effect of frequency and code resources is often quite different from the actual situation. Due to the coverage problems of some base stations, it often leads to serious in-band interference in related areas. [0003] In addition, with the development of user scale and business, the network capacity continues to increase, and the reuse of frequency and code resources also continues to rise. In high-density service hotspot areas, there are often high-capacity configurations where the distance betwe...
