MOBILE COMMUNICATION SYSTEM, BASE STATION DEVICE, AND MOBILE STATION DEVICE

摘要

PROBLEM TO BE SOLVED: To transmit highly reliable reception quality information to a base station device by sufficiently securing the time (integration time) for measuring reception quality for information to be transmitted in downlink. SOLUTION: The mobile communication system includes a mobile station device 200 measures reception quality of a signal received from the base station device 100 and transmits reception quality information to the base station device 100. The base station device 100 adds transmission timing delay information instructing transmission of the reception quality information in non-periodic timing to the mobile station device 200 to an uplink data transmission permission signal and transmits it to the mobile station device 200. In a case where the uplink data transmission permission signal including the transmission timing delay information is received from the base station device 100, the mobile station device 200 transmits the reception quality information to the base station device 100 in timing instructed by the transmission timing delay information.
