Method for connecting mobile station to base station, mobile station, base station, multi-carrier mobile communication system, and random access channel mapping method

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.

1. A processing method of a mobile station, wherein a random access channel having guard time and a control channel in an uplink line from the mobile station to a base station are provided, the method comprising:
obtaining, by the mobile station, correction information for correcting a transmission timing shift in an uplink line of the mobile station from the base station; correcting, by the mobile station, the transmission timing shift according to the correction information; and requesting, by the mobile station to the base station, communication resource allocation information of transmission data to the base station using the random access channel having the guard time within a period in which the correction information is valid when a communication resource for transmitting the control channel in the uplink line is not assigned to the mobile station.
