Abstract: A communication control method according to an embodiment comprises: receiving, by a first network apparatus, first information from a first user terminal, the first network apparatus configured to belong to a first Public Land Mobile Network (PLMN); and notifying, the first network apparatus, the first user terminal of second information. The first information includes a first identifier included in a discovery signal which the first user terminal has directly received from a second user terminal. The second information includes information corresponding to the first identifier. The communication control method further comprises determining, by the first network apparatus, in response to receiving the first information, whether the first identifier is a second identifier allocated in the first PLMN. The first network apparatus notifies the first user terminal of the second information in response to determining that the first identifier is the second identifier.

Abstract: In a mobile communication system, a base station performs downlink multi-antenna transmission by applying a precoder matrix for defining downlink transmission directivity. The mobile communication system includes a first user terminal that selects one of first precoder matrix information and second precoder matrix information as precoder matrix information to be fed back to the base station. The precoder matrix information is referred to determine, in the base station, the precoder matrix to be applied to transmission to a second user terminal that establishes a connection with the base station. The first precoder matrix information indicates the precoder matrix that is preferred to the first user terminal. The second precoder matrix information indicates the precoder matrix that is not preferred to the first user terminal.
