Problems solved by technology

However, this way of sharing the spectrum has caused interference problems between the nodes with the same coverage, especially the interference from the macro base station to the downlink reception of the users in the small base station, and the interference from the high-power terminal users at the edge of the macro base station to the nearby small base stations

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 present invention includes the following steps: Step 1. For each user who needs base station services, calculate the user's interference protection radius r according to the user coverage probability P greater than the threshold value β 0 ; Step 2, take the user as the center, and the circular area with the interference protection radius as the radius is the interference protection area of ​​the user; Step 3, record the available wireless resource set of the macro base station and all small base stations as Ω, and the current user interference protection area The wireless resource occupied by the base station is denoted as R, where the available wireless resource of the current user can only be selected from the wireless resource set Ω\R, that is, the small base station inside the interference protection area of ​​the current user cannot communicate with the main service of the current user The base stations share radio resources. The present invention can effectively suppress co-frequency interference, improve frequency spectrum utilization, increase system coverage probability, and improve user performance 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...
