Problems solved by technology

[0003] In the process of realizing the present invention, the inventors found that although the methods of improving channel quality in the prior art can meet the reliability of data transmission, there are some problems: for example, for inter-cell cooperation technology, multiple base stations transmit to the same user For the same content, the waste of resources is serious and the cost is high
For relay technology, users and base stations interact through relay stations, and the cost of deploying relay stations is also high
In addition, it is difficult to guarantee services that require relatively high data transmission rates or cause increased costs.

Abstract

The invention discloses a method, equipment and a system for transmitting data. The method comprises the following steps that: a first class of user terminal serves as a relay user node between a second class of user terminal and a network side; and the second class of user terminal forwards data messages to the network side through the first class of user terminal. By the method, the equipment and the system, the cost can be reduced, the transmission rate can be improved, and the technical defect that service with high requirements on data transmission rates is difficult to guarantee or the manufacturing cost is increased in the prior art is overcome.

Description

technical field [0001] The present invention relates to the technology in the field of wireless communication, and in particular, to a data transmission method, device and system. Background technique [0002] With the development of mobile communication services, users have higher and higher requirements on the transmission rate of data services. The channel quality of users who are relatively close to the base station is relatively ideal, and the transmission rate can be increased through multiple antenna multiplexing technology (MIMO, multiple input multiple output) or high-order modulation and coding methods to meet user service needs. For users far away from the base station, or users in an environment with many obstacles, the channel quality is not ideal. Multi-antenna diversity or inter-cell cooperation technology can be used to improve user communication quality, or relay stations (Type1 relay) can be used to expand coverage. , to ensure the reliability of data tran...
