The present application provides a communication method and device, which relate to the technical field of wireless communication and are used to solve the problem of large differences in uplink coverage performance of different terminal devices within the coverage of network devices. The method includes: a relay device receives a power parameter from a network device, the power parameter corresponds to a first terminal device; the relay device receives a first signal from the first terminal device; the relay device receives a first signal from the first terminal device; The signal and the power parameter determine the first transmit power of the second signal; the relay device uses the first transmit power to send the second signal to the network device. Based on this solution, the relay device can determine the transmit power when forwarding signals of different terminal devices within the coverage of the network device according to the power parameters sent by the network device, so that the signal transmission gains for different terminal devices are different, so that each The signal transmission performance of the terminal equipment is similar, which improves the coverage performance of the terminal equipment.
