Embodiment Construction

[0040] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with specific embodiments. It should be understood that the invention is not limited to the specific examples.

[0041] figure 1 and 2 A system frame diagram of the present invention is shown, which includes a base station controller 1, a mobile terminal 2 and multiple base stations (including the source base station 3 to which the mobile terminal belongs and other adjacent base stations around the mobile terminal).

[0042] In the adaptive compound open-loop multi-antenna macro-diversity technical solution of the present invention, firstly, the mobile terminal 2 continuously measures the signal strength from the source base station 3 and the signal strength from neighboring base stations during the moving process. Within a period of time, if the signal strength from the source base station 3 is greater than the signal strength of the adjacent base st...

Abstract

The invention discloses a technological scheme of self-adaptive multi-antenna great-diversity, which is characterized by the following: selecting fitful antenna for the same base station or different base stations according to positional information in different honeycomb deme regions of mobile terminal; adopting self-adaptive multi-output and input (MIMO) transmission technology to form self-adaptive compound multi-antenna great-diversity scheme; reducing adjacent regional interference problem effectively; obtaining superior entire system property than traditional multi-antenna.

Description

technical field [0001] The present invention relates to a mobile communication network, and more particularly, to the technology of multi-antenna macro-diversity in a cellular communication network. Background technique [0002] With the rapid development of wireless communication technology, the serious shortage of spectrum resources has increasingly become a bottleneck to curb the wireless communication business. How to fully develop and utilize limited spectrum resources and improve spectrum utilization is one of the hotspots in the current wireless communication field. Among them, multiple-input multiple-output (MIMO) wireless communication technology is currently a key technology for improving spectrum utilization in the field of mobile communication. [0003] The concept of multiple-input multiple-output (MIMO) wireless communication technology is very simple. Any wireless communication system that uses multiple antennas or antenna arrays at its transmitting end and r...
