Abstract

The invention provides a CoMP (coordinated multiple point transmission / reception) multi-user scheduling method based on QoE (quality of experience). The method includes: grouting users, to be more specific, grouping the users into several groups according to the large-scale channel response of the base station of the cells where the users are located; determining user priority, to be more specific, determining the subjective QoE priority of the users according to the subjective wills of the users to business, determining the objective QoE priority of the users, and synthesizing the subjective priority and the object priority to determine the final priority of the user; scheduling the users, to be more specific, scheduling the users according to the grouping and the priority. By the method, user capacity is increased greatly by reasonable scheduling while cell throughput rate is guaranteed and the high-QoE users are scheduled preferentially.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a multi-user scheduling method of CoMP (Coordinated Multiple Point transmission / reception). Background technique [0002] In a cellular communication system, in order to make full use of wireless spectrum resources, a reuse factor of 1 is used. However, while improving spectrum efficiency, it brings interference between adjacent cells, especially for users located at the edge of the cell, which is very serious. Therefore, the key technology of coordinated multi-point transmission (CoMP) is introduced in LTE-A (Long Term Evolution Advanced). CoMP provides services for multiple users at the same time through the cooperation of several adjacent cells. It can use resources such as multiple base stations, multiple antennas, and multiple users to turn inter-cell interference signals into useful signals and greatly improve the performance of the entire system. . [0003] In CoMP...
