Problems solved by technology

[0005] In the traditional NR scheduling algorithm, frequency selection scheduling is performed only according to the subband report of the UE, but the CQI (channel quality indicator, channel quality indicator) report of the subband has a relatively small granularity and cannot indicate the level of interference. For the UE, if the traffic volume is relatively large, PRBs (Physical Resource Blocks) with high and low interference will be scheduled together, resulting in decoding failure and decreased throughput. to interfere

Abstract

The embodiment of the invention provides an interference detection method and device, electronic equipment and a storage medium, and relates to the technical field of communication. The method comprises the following steps: receiving channel state information reference signals (CSI-RSs) reported by at least one candidate terminal and at a plurality of moments; according to the CQI of the coincident sub-band in the CSI-RS at the multiple moments, determining the number of times that the coincident sub-band reported by each candidate terminal in the at least one candidate terminal is interfered; and determining an interfered sub-band in the overlapped sub-bands according to the interfered times of the overlapped sub-bands reported by each candidate terminal in the at least one candidate terminal. According to the embodiment of the invention, the problem of low accuracy caused by determining the interfered sub-band based on the CQI at a single moment can be avoided, a foundation is laid for solving the problem of low throughput caused by the interfered sub-band, and the service level of a network is improved.

Description

technical field [0001] The present application relates to the field of communication technologies, and in particular, the present application relates to an interference detection method, an apparatus, an electronic device, and a storage medium. Background technique [0002] When multiple communication systems are networked together, the bandwidths of different communication systems overlap, and the overlapping bandwidths will cause serious interference to different communication systems. For example, when a new radio (NR) system and a long term evolution (LTE) system are jointly networked, the LTE base station is not completely disconnected from the network, and the NR base station may be interfered by surrounding LTE base stations. [0003] For example, the NR system occupies 100MHz bandwidth, but the 40MHz bandwidth overlaps with the two 20MHz bandwidths of the LTE system. Therefore, if the LTE cell and the NR cell cover the same or overlap, they will cause serious interfe...
