Abstract: A mobile communication system performs multi-antenna transmission by applying a pre coder matrix for determining transmission directionality. The mobile communication system comprises a user terminal that starts feedback of predetermined precoder matrix information to a node in response to an instruction from the node controlling communication. The predetermined precoder matrix information is used to decide the precoder matrix that is applied to transmission to another user terminal different from the user terminal. The user terminal comprises: a control unit that switches whether to stop the feedback after starting the feedback in response to the instruction.
