Abstract:
A mobile station (MS) obtains a parameter, performs transmission of a preamble, and sets a counter incremented based on transmission of the preamble. The MS is able to indicate a random access problem corresponding to one transmission timing cell group in a case where the counter reaches the parameter +1 and the transmission of the preamble is performed on the one transmission timing cell group, where the one transmission timing cell group being one of the plurality of transmission timing cell groups, and the MS is able to not indicate a random access problem corresponding to another transmission timing cell group in a case where the counter reaches the parameter +1 and the transmission of the preamble is performed on the another transmission timing cell group, where the another transmission timing cell group being one of the plurality of transmission timing cell groups.
