at least one processor;
and
one or more memories coupled to the at least one processor and storing programming instructions for execution by the at least one processor to instruct the first BBU to:
obtain first clock synchronization information, wherein the first clock synchronization information comprises a clock frequency and a clock phase of the first BBU;
and
send the first clock synchronization information to the second BBU;
and
wherein the one or more memories store the programming instructions for execution by the at least one processor to instruct the second BBU to:
receive first clock synchronization information sent by the first BBU;
and
configure local clock information of the second BBU based on the first clock synchronization information.
