Patent Searching and Data

A mobile communication system, a mobile communication method, and a base transceiver station
Document Type and Number:
Japanese Patent JP6017558
Kind Code:
A mobile communication system directly performs user-data communication between a plurality of radio terminals without involvement of a radio base station. The user-data communication directly performed between the plurality of radio terminals is performed by using a part of radio resources assigned to the mobile communication system. The plurality of radio terminals include a transmission-side terminal that transmits the user data and a reception-side terminal that receives the user data. The mobile communication system switches between a first assignment mode in which the transmission-side terminal or the reception-side terminal assigns a radio resource used for the user-data communication, and a second assignment mode in which the radio base station assigns the radio resource used for the user-data communication.
