Problems solved by technology

[0009] The purpose of the present invention is to provide a control method of multi-antenna communication mode in a mobile communication system to solve the problem of using relatively fixed multi-antenna communication mode in the prior art. The communication between the terminal and the network side, resulting in inflexible control of the multi-antenna communication mode, which in turn leads to technical problems that cannot receive data accurately or cannot meet the high-speed requirements of the terminal

Embodiment Construction

[0037] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0038] Considering the problems caused by the relatively fixed multi-antenna communication mode used by the existing communication system to communicate between the terminal and the network side, the applicant has devoted himself to research and found that various multi-antenna communication modes have their own advantages and applicable occasions. Therefore, the present invention proposes a multi-antenna communication method for adaptively selecting the terminal to communicate with the network side according to information such as channel correlation information (including channel correlation, signal-to-noise ratio of received signals) and the location of the user, so as to be able to To maximize the advantages of multi-antenna technology.

[0039] see figure 1 , which is a control method of a multi-antenna communication mode in a mobile communication system of th...

Abstract

The key idea of method is: according to the user's location information, channel dependency information and received signals S / N ratio information, the communication system self-adaptively selects the multi antenna communication way at terminal side and network side. It comprises: 1) deciding if user locates at switching area; if yes, the system will operates at single cell mode or multi cell mode according to the presetting; otherwise, the system operates at single cell mode; 2) according to the channel dependency and / or S / N ratio of received signals, the system decides if the system will works at single-cell mode or at multi-cell mode.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method for controlling a multi-antenna communication mode in a communication system, in particular to adaptively changing the multi-antenna working communication mode in a mobile communication system according to the signal-to-noise ratio and channel correlation of received signals. Background technique [0002] In a traditional mobile communication system, a terminal is usually provided with a single antenna, and the terminal communicates with the network side through a single-antenna working mode. However, with the development of services such as high-speed data, the single-antenna working mode is far from meeting its needs. For this reason, multi-antenna technology has been proposed and developed rapidly. The so-called multi-antenna means that both the terminal and the base station have multiple antennas. [0003] The communication mode of multi-antenna work in the mobile...
