METHOD, DEVICE AND SYSTEM FOR DATA TRANSMISSION

摘要

A method, device and system for data transmission. The method includes: taking a first user terminal as a relay user node between a second user terminal and the network side; and forwarding from the first user terminal a data message interacted between the second user terminal and the network side. The channel quality and transmission rate can be improved, the technical defect in the prior art resolving that it is difficult for those user services requiring a high data transmission rate to obtain a guarantee of reliability.
