1. A method for random access in a wireless communication system including a base station and a wireless terminal, the method comprising:
at the wireless terminal, recognizing a multiple allocation of random access preambles including a first random access preamble and a second random access preamble, the second random access preamble being received from the base station; and performing only one random access procedure among a first random access procedure using the first random access preamble and a second random access procedure using the second random access preamble, in a case of receiving a new request requesting for one random access procedure among the first random access procedure and the second random access procedure while another random access procedure among the first random access procedure and the second random access procedure is already ongoing.
