Abstract:
A method for reporting an optimal beam includes: a MSG3 is sent to a base station on a measured optimal beam; and a MSG4 returned by the base station is waited to be received on both the optimal beam and an initial beam originally configured to send the MSG3. As the MSG3 is sent to the base station on a measured optimal beam, the optimal beam can be reported implicitly in the random-access process; and as no bit for representing beam information needs to be additionally defined, resources can be saved.
