Abstract: In a communication system according to the present invention, a UE and an Men perform both a direct communication and a communication through a SeNB. Along with moving of the UE, a handover process of switching the MeNB to which the UE is connected, from an S-MeNB to a T-MeNB is performed. The connection between the UE and the SeNB is maintained during the handover process. The UE starts transmitting data to the SeNB before a communication path between the UE and the MeNB is changed from a path formed by the S-MeNB and the UE to a path formed by the T-MeNB and the UE.

Abstract: The object of the present disclosure is to provide a radio communication control method and a radio communication apparatus which allow efficient avoidance of the influence of noise. The radio communication control method according to the present disclosure includes: a first process of obtaining a received field strength of a preamble signal received through radio communication; a second process of calculating a receiving sensitivity estimated value as an estimated value of a receiving sensitivity, based on a radio frequency used in the radio communication and an amount of receiving sensitivity degradation as an amount of degradation in the receiving sensitivity which is caused by an operation of at least one interface; and a third process of controlling the operation of the at least one interface being activated, based on the received field strength obtained in the first process and the receiving sensitivity estimated value calculated in the second process.
