摘要： In a mobile station, correction information is obtained from a base station for correcting a transmission timing shift in an uplink line of the mobile station, and the transmission timing shift is corrected in accordance with the correction information. Within a period in which the correction information is valid, the mobile station requests communication resource allocation information from the base station, using a random access channel having guard time. In an alternate embodiment, if a communication resource for transmitting a control channel in the uplink line is assigned to the mobile station within a period during which the correction information is valid, the mobile station instead requests the communication resource allocation information from the base station using the control channel in an uplink line from the mobile station to the base station.
