Abstract
This application provides a communication method and a device. The method includes: sending, by a terminal device to a network device, a random access preamble, receiving, by the terminal device, a random access response (RAR) from the network device, wherein the RAR indicates a first resource, and sending, by the terminal device, downlink channel quality indication information to the network device, wherein the downlink channel quality indication information is carried in a Message 3 on the first resource, and the downlink channel quality indication information is used to indicate downlink channel quality.
