METHOD OF RANDOM ACCESS IN RADIO COMMUNICATION SYSTEM, RADIO COMMUNICATION SYSTEM, RADIO TERMINAL AND BASE STATION DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a radio terminal where either of a plurality of random accesses can be selectively carried out.

SOLUTION: If first information for use in a first random access and second information for use in a second random access received from a base station device are detected, a radio terminal selects either one of the first information and the second information. Also, during continuation or after completion of one random access using the selected information, the radio terminal transmits third information to be transmitted to the base station device in a process of the other random access which is not selected.
