Abstract

The invention relates to a down-link cell-edge user determination method and a down-link cell-edge user determination device with an aim to solve the problem about poor accuracy existing in the cell-edge user determination method in the prior art. The down-link cell-edge user determination method includes: S1, acquiring reference signal received power (RSRP) of a service cell where a target user is located and reference signal received power of multiple neighboring cells, and taking the neighboring cell with the largest reference signal received power as the strongest neighboring cell; judging whether or not (RSRPservice-RSRPneighbor) is smaller than RSRPthi and RSRPneighbor is greater than RSRPth2, and if yes, identifying the target user as a cell-edge user. Two judgment conditions that (RSRPservice-RSRPneighbor) is smaller than RSRPthi and RSRPneighbor is greater than RSRPth2 are adopted, the RSRP of the target user in the service cell is taken into consideration, the RSRP of the neighboring cells is also considered, ignorance of interference factors of the neighboring cells is avoided, and accuracy in determining the cell-edge users in improved.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, in particular to a downlink edge user determination method and a downlink edge user determination device. Background technique [0002] In a communication system, spectrum utilization rate and service quality (Quality of Service, QoS for short) are important performance indicators of the system. In order to achieve high spectral efficiency, the frequency reuse factor should be as close to 1 as possible when deploying the network. In order to provide satisfactory services, it is necessary to ensure the QoS of users, especially cell edge users. The Long Term Evolution (LTE for short) system uses Orthogonal Frequency Division Multiplexing (OFDM for short) technology to carry user information on different carriers that are orthogonal to each other to combat frequency selective fading and eliminate Interference between users in the same cell. In this case, all interference come...
