Problems solved by technology

[0003] However, in the hybrid networking architecture composed of the MIMO system and the traditional single-transmission system, due to the different transmit powers of the MIMO system and the traditional single-transmission system, the power of each physical antenna is unbalanced, which makes MIMO unable to achieve the best performance.

Abstract

Embodiments of the present invention provide a method, device and system for transmitting data in a hybrid network. The method includes: determining in the hybrid network the order number N of the highest order multiple-input multiple-output MIMO data and a number M of data types, N being an even number no less than 2, and M being a natural number no less than 2; obtaining, by means of the i-th linear transformation of the i-th data in the M types of data, a number N of i-th output data of equal power, wherein i is a natural number less than or equal to M; outputting the number N of i-th output data of equal power to a number N of physical antennas respectively, so that the received output data are merged and transmitted by each physical antenna. The present invention makes possible the power balance of each radio channel in a hybrid network.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a method, device and system for sending data in a hybrid network. Background technique [0002] The Multiple-Input Multiple-Output (MIMO) system uses multiple transmitting antennas and receiving antennas at the transmitting end and receiving end respectively, and signals are transmitted and received through multiple antennas at the transmitting end and receiving end, thereby improving each quality of service for each user. Although the MIMO technology is more and more widely used, the traditional single-input single-output (Single-Input Single-Output, SISO) technology is still adopted. Therefore, the hybrid networking architecture composed of the MIMO system and the traditional single-transmission system is widely used. [0003] However, in the hybrid networking architecture composed of the MIMO system and the traditional single-transmission system, the power of each physica...
