Title:
COMMUNICATION METHOD AND DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/138919
Kind Code:
A1
Abstract:
The present application relates to the technical field of wireless communications, and provides a communication method and device, for solving a problem of large difference in uplink coverage performance of different terminal devices in a coverage range of a network device. The method comprises: a relay device receives a power parameter from a network device, the power parameter corresponding to a first terminal device; the relay device receives a first signal from the first terminal device; the relay device determines a first transmit power of a second signal according to the first signal and the power parameter; the relay device sends the second signal to the network device by using the first transmit power. On the basis of the solution, the relay device can determine, according to a power parameter sent by a network device, the transmit power when signals of different terminal devices in a coverage range of a network device are forwarded, so that signal transmission gains of different terminal devices are different, thus the signal transmission performance of the terminal devices is similar, and the coverage performance of the terminal devices is improved.
