PROBLEM TO BE SOLVED: To provide a more robust scheme for providing precoding information in a mobile communication system. SOLUTION: A receiver apparatus (700) for providing precoding information comprises: a detector (710) for detecting an event and a transmit unit (720) for transmitting absolute precoding information at a first time instant in response to a detected occurrence of the event and for transmitting differential precoding information at a second time instant different from the first time instant.
