Abstract

The invention discloses a clustering method for reducing interference increments, comprising: randomly dividing all users into a first group and a second group; calculating interference weights Wab among all users in the first group and the second group respectively; Determine the user m and user n corresponding to the maximum interference weight Wab in the two groups; calculate △Pm, △Nm, △Pn and △Nn, and determine △m and △n; according to the size relationship between △m and △n, further Determine whether to switch user m and user n to another group, and repeat the above steps to complete the clustering calculation. Therefore, the clustering method for reducing the interference increment provided by the embodiment of the present invention divides the users into two clusters randomly, and performs repeated exchanges according to the interference weights of the users until there is no exchangeable, so as to reduce user interference. This method has lower calculation load, reduces inter-cluster interference, and improves clustering gain.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a clustering method for reducing interference increment. Background technique [0002] One of the trends in future mobile communication development is high-speed broadband and rapid data growth. In order to expand system capacity, the most common method is to use cell densification, such as the formation of micro cells and pico cells. However, the resulting inter-cell interference has become the main factor limiting the communication performance of cell edge users. Interference cancellation is a way of eliminating inter-cell interference. In order to better improve the communication performance of cell edge users, a cooperative transmission technology is proposed. This technology reduces the inter-cell interference and enhances the communication performance of edge users by performing joint processing or cooperative scheduling on the inter-cell interference suffered by cel...
