Embodiment 1

[0029] An interference coordination method based on interference protection areas of the present invention will be described below with reference to the accompanying drawings and in combination with preferred embodiments of the present invention.

[0030] In this embodiment, only frequency resources are multiplexed and allocated. At this time, Ω and R are simplified as frequency sets, and Ω is an available frequency set of the entire system.

[0031] see figure 1 , the method for dividing the interference protection area and the frequency resource allocation method for the macro user of the macro base station-home base station two-layer network in the present invention. According to the method proposed by the present invention, the interference protection area and wireless resource allocation of users of any layer can be designed, thereby solving the interference suppression problem of multi-layer heterogeneous networks.

[0032] Step 1: According to P(SINR>T)>β, calculate th...

Abstract

The invention discloses an interference coordination method based on an interference protection area. The method comprises the steps of: 1, calculating interference protection radiuses r0 of users needing base station services according to the fact that a user coverage probability P is greater than a threshold value [beta]; 2, taking the users as centers, and taking circular areas in which the interference protection radiuses are taken as radiuses as interference protection areas of the users; and 3, marking an available wireless resource set of a macro base station and all small-sized base stations as [omega], and marking wireless resources already occupied by the base stations inside the interference protection area of a current user as [R], wherein [R] is a proper subset of [omega], and the available wireless resources of the current user can only be selected from a wireless resource set [omega]\R, namely, the small-sized base stations inside the interference protection area of the current user cannot share the wireless resources with a master service base station of the current user. Through adoption of the interference coordination method, same frequency interference can be suppressed effectively; the spectrum utilization ratio is increased; the system coverage probability is increased; and the performance of the users is improved at the same time.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to an interference coordination method for wireless homogeneous or heterogeneous networks. The multiple access technology may be frequency division multiple access (Frequency Division Multiple Access: FDMA), orthogonal frequency division multiple access (Orthogonal Frequency Division Multiple Access: OFDMA) and other multiple access technologies. Background technique [0002] In recent years, the mobile communication industry is facing an opportunity for substantial development. The fourth generation (4G) system has gradually been commercialized around the world, and the fifth generation (5G) mobile communication technology has also been adopted by various research organizations, mobile communication operators, and international organizations. attention of standardization organizations. From the perspective of the industry's vision for 5G, 5G will have ultra-high spectrum ut...
