AI summary

A method of bandwidth part (BWP) management for a network is provided. Position information of user equipments is received. Whether interference exists between any two of the user equipments is determined based on the position information of the user equipments and the position information of the base stations to obtain an interference status of the user equipments. Interference exists between user equipment(s) of any two base stations in each of the at least one base station combination. Interference exists between a first user equipment and a second user equipment in a first base station combination. BWP resource allocation is performed based on the at least one base station combination and the interference status of the user equipments to obtain a BWP resource allocation result. The first user equipment is assigned with a first BWP frequency band and the second user equipment is assigned with a second BWP frequency band.
