Description

Dense cell interference coordination method and device

Technical Field

The present application relates to the field of mobile communications, and in particular, to a method and an apparatus for coordinating interference in a dense cell.

Background

The fifth generation mobile communication technology (5 g) network needs to support 1000 times of increase of traffic volume, and the core technology is to deploy a super-dense network, and increase the number of low power stations and reduce the radius of a cell to improve the transmission capability of a unit area and increase the system capacity. In an ultra-dense network scene, the deployment density of stations is increased, and the distance between stations is reduced, which leads to more serious inter-cell interference. At the cell edge, the user rate and experience are difficult to be effectively improved. And as the number of neighboring stations increases, there may be multiple interferers of close strength, making the interference situation more complex. How to avoid inter-cell interference through site cooperation is an important problem to be solved by ultra-dense networks.

The basic idea of inter-cell interference coordination is to coordinate the scheduling and allocation of resources among cells according to certain rules and methods to reduce inter-cell interference. In order to complete interference coordination between cells in time domain, the concept of Almost Blank Subframe (ABS) is introduced. For the ABS, only some necessary paging or system message signals are included, and the configured power is very low, so that the ABS is configured in the interfering cell, and the interfered cell schedules the user at the position of the ABS, thereby implementing inter-cell interference coordination in the time domain.

In the time domain inter-cell interference coordination under the ultra-dense networking scene, the key is to determine the ABS patterns used by the interfering cell and the interfered cell. In a traditional mode, after an interfered cell discovers an interfering cell for a certain user, according to a network quality condition fed back by the user, an interference coordination request between time domain cells is sent to the interfering cell, then the interfering cell sends an ABS pattern set to the interfered cell, the interfered cell selects an ABS pattern and then feeds the ABS pattern back to the interfering cell for confirmation, and then resource scheduling is carried out based on the confirmed pattern; or the interfered cell directly sends an ABS pattern set to the interfering cell, and after the interfering cell selects one ABS pattern, the interfering cell and the interfered cell perform resource scheduling based on the confirmed pattern. However, with the rapid development of mobile internet services and the rise of 5G + vertical industry services, richer service types gradually appear, and the requirements for mobile networks, especially service guarantees, are more diverse, whereas the time domain inter-cell interference coordination method in the existing ultra-dense networking scenario cannot provide sufficient network guarantees in the dense cell networking scenario in the 5G environment.
