Preferred embodiments of this invention provide a base station and a terminal appropriate for a protocol for realizing a high performance and a low delay by relaying in a base station only if a direct transmission is not performed between terminals and omitting a data transmission channel for relaying if the direct transmission is performed. When a receiver terminal receives data directly from a sender terminal, the receiver terminal transmits a report of a direct receipt of the data to the base station. When the base station receives the report of the direct receipt of the data, the base station omits the data transmission channel for relaying.
