Embodiment Construction

[0073] In order to make the above objects, features and advantages of the present application more obvious and comprehensible, the present application will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0074] One of the core concepts of the embodiments of the present application is to dynamically adjust the carrier resource allocation of small cells according to the load information and interference information of adjacent small cells, so that the carriers between small cells are staggered as much as possible, so as to reduce the number of small cells. At the same time, the carrier resource allocation of each small cell is adaptive to its cell load status, thereby improving spectrum resource utilization and user experience.

[0075] refer to figure 1 , which shows a flow chart of the steps of Embodiment 1 of a method for dynamic carrier adjustment of a small cell of the present application, wherein the...

Abstract

An embodiment of the present application provides a method for dynamic carrier adjustment of a small cell, including: when the interference information of the target small cell is greater than the preset upper interference threshold and the load information is lower than the preset lower load threshold, deleting the target small cell The first carrier in the carrier set; the first carrier is the overlapping carrier between the target small cell and its neighbors; when the interference information of the target small cell is greater than the preset interference upper threshold, and the load information is higher than the preset load working threshold, delete The second carrier in the working carrier set of each neighboring cell of the target small cell; the second carrier is an overlapping carrier between each neighboring cell and the target small cell; when the load information of the target small cell is higher than the preset load upper threshold, the target Carriers are added to the working carrier set of the small cell. According to the load information and interference information of adjacent small cells, the embodiment of the present application dynamically adjusts carrier resource allocation of small cells, so that carriers between small cells are staggered as much as possible, thereby reducing interference between small cells.

Description

technical field [0001] The present application relates to the field of communication technologies, and in particular to a method for dynamically adjusting a carrier of a small cell and a device for dynamically adjusting a carrier of a small cell. Background technique [0002] With the vigorous development of mobile broadband technology, various smart terminals bring a blowout growth of data services. At the same time, more and more data traffic is concentrated in indoor and outdoor hot spots. Traditional macro base stations have encountered bottlenecks in network construction and coverage. In order to achieve deep network coverage and capacity improvement, and taking into account cost effects, operators have turned more attention to small cells (Small Cells). Small cells can well meet the requirements of providing high data rate services with high service quality and low cost. [0003] In LTE (Long Term Evolution, Long Term Evolution) spectrum planning, TD-LTE (Time Divisi...
