Timing adjustment method, user equipment, base station, and mobile communication system

摘要

In response to receiving second transmission timing adjustment information (TA #2) during connection processing while the user equipment (20) is performing the connection processing to the base station (10) based on first transmission timing adjustment information (TA#1), the first transmission timing adjustment information (TA #1) is applied to transmission timing adjustment for transmission processing until a valid term of the first transmission timing adjustment information (TA #1); and the second transmission timing adjustment information (TA #2) is applied to transmission timing adjustment for transmission processing after the valid term of the first transmission timing adjustment information (TA #1).
