A communication system includes a mobile station and a base station. The mobile station calculates estimated TA information based on the position of the mobile station and an amount of propagation path delay. The mobile station determines, based on TA information transmitted from the base station and the estimated TA information, whether the TA information is addressed thereto. The mobile station determines whether to transmit "Message 3" to the base station depending on determination results, and transmits "Message 3" when the TA information is addressed thereto.
