Abstract
A wireless terminal capable of communicating with a wireless communication system comprised of a plurality of wireless terminals and a plurality of base stations. The wireless terminal selects a sequence from a group of certain sequences for random access. At least one sub-carriers on an uplink channel including at least one data channel is allocated for at least one random access channel. Each data channel includes a continuous set of data sub-carriers. The wireless terminal then filters the at least one random access channel by applying a Raised Cosine filter, maps the selected sequence to the at least one random access channel to generate a random access channel signal, and transmits the random access channel signal to a base station.
