AI Technical Summary

Problems solved by technology

[0008] To sum up, static interference coordination cannot reasonably allocate edge frequency band resources according to user load changes, and the spectrum utilization rate is low.
In the current method of dynamically dividing the edge frequency band, the division of the edge frequency band of the current cell refers to the load information of the entire cell of the neighboring cell, not the edge load information, resulting in inaccurate basis for dividing the frequency band

Abstract

The present invention provides a method and device for dynamically dividing edge frequency bands. The method for dynamically dividing edge frequency bands includes: obtaining frequency band resources required by all edge users in this cell at each preset timing period, and receiving frequency band resources sent by neighboring cells. Edge frequency band information: determine the edge frequency band information of the cell according to the frequency band resources required by all edge users in the cell and the edge frequency band information of neighboring cells. The invention can rationally allocate the edge frequency band occupied by each cell and improve the throughput of the system.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method and device for dynamically dividing edge frequency bands. Background technique [0002] In a communication system, spectrum utilization and service quality (QoS) 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) system adopts Orthogonal Frequency Division Multiplexing (OFDM) technology. OFDM technology uses the orthogonality between frequencies as a way to distinguish users, and carries user information on each other. On different orthogonal carriers, it can effectively resist frequency selective fading. In addition, since the frequencies used by users in a cell are orthogonal to eac...
