Abstract

The invention relates to the technical field of communication, in particular to a user interference degree-based frequency domain resource allocation method in a wireless network, which comprises the following steps of: acquiring a UE (User Equipment) interference list corresponding to each user in a cell, and determining the interference degree of each user in the cell according to the UE interference list corresponding to each user in the cell; in a frequency domain resource position allocation stage of a scheduling process, according to the interference degree of each user in a cell and the number of RBs required by each user, frequency domain resources are sequentially allocated to each user in the cell, and the frequency domain resources are allocated from an edge resource initial position according to a resource allocation direction. Wherein the users with stronger interference degree in the cell distribute resource positions preferentially, and the users with weaker interference degree or without interference distribute resource positions later. According to the invention, based on the interference degree of the user, the resource position is preferentially allocated for the user with relatively strong interference degree, the allocation reasonability of the spectrum resource is improved, and various problems of the traditional ICIC are effectively solved.

Description

technical field [0001] The present invention relates to the technical field of 5G communication, in particular to a frequency domain resource allocation method in a wireless network based on the degree of user interference. Background technique [0002] Since 2017, the Ministry of Industry and Information Technology has authorized different 5G spectrums to three operators and radio and television. Among them, China Mobile 5G spectrum: N41 NR / LTE: TDD 2515-2675 bandwidth 160M, N79 NR: TDD 4800-4900 bandwidth 100M; China Telecom N78 NR: TDD 3300-3400 bandwidth 100M, N78 NR: TDD 3400-3500 bandwidth 100M; China Unicom N78 NR: TDD 3300-3400 bandwidth 100M, N78 NR: TDD 3500-3600 bandwidth 100M; China Radio and Television: N28 NR: FDD 703 -733 758-788 bandwidth 30M, N79 NR: TDD 4900-4960 bandwidth 60M, N78 NR: TDD 3300-3400 bandwidth 100M. [0003] Limited by industrial chain development and network planning, operators often choose one or two 5G frequency bands to build 5G. For ex...
