Embodiment Construction

[0030] The present invention will be further explained below in conjunction with specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and not to limit the scope of the present invention. In addition, it should be understood that after reading the teachings of the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms also fall within the scope defined by the appended claims of this application.

[0031] In the present invention, single antennas belonging to different base stations form a distributed multi-antenna system under the action of a centralized control terminal, and at the same time, the distributed multi-antenna system is adaptively divided into different clusters according to the distribution of users. Multiple base stations and their multiple antennas provide communication services for users in these clusters. In this w...

Abstract

The invention provides a microcellular multi-antenna system adaptive clustering adjusting method. The method comprises steps that the plurality of single-antenna microcellular base stations are managed in a unified manner by using a concentrated control terminal, and the plurality of antennas of the microcellular base stations form the distributed multi-antenna system with the action of the concentrated control terminal; the microcellular base stations in the region are evenly distributed to multiple clusters; each cluster achieves distributed wave beam forming for mobile users in the cluster; the access user number and the signal to noise ratio condition of each cluster obtained by feedback are subjected to statistics; according to the statistics condition, adaptive adjustment of the number of the microcellular base stations in each cluster is carried out, and the emission power is adjusted with the combination of the distributed wave beam forming, so that the communication quality of the mobile users can be ensured; and the concentrated control terminal adjusts the emission power in each cluster, and the inter-cluster interference is reduced under the precondition of meeting the intra-cluster communication. The method reduces the interference of the whole microcellular system while improving the communication quality.

Description

Technical field [0001] The invention relates to an adjustment method for adaptive clustering of a microcellular multi-antenna system, belonging to the technical field of communication. Background technique [0002] The advantage of micro-cell technology is to use indoor fixed-line lines and the combination of the Internet and wireless access, so that the wireless base station of the micro-cell realizes high-speed wireless access to indoor users. At present, the research on microcells mainly focuses on the research on the protocol, signaling and high-speed packet transmission of the interconnection between microcells and macrocells, while the research on the microcell base station itself, especially the use of multiple antennas at the microcell base station Technical research is very limited. [0003] In terms of theoretical research on microcellular systems, the literature (An Overview of the femtocell concept, Bell LABS TECHNICAL JOURNAL, Article first published online: 15MAY2008...
