Claim Text:
1. A method for a mobile terminal to request a random access connection, the method comprising: obtaining, by the mobile terminal, first information indicating a signature root sequence index and a cyclic shift parameter; receiving, by the mobile terminal from a base station, second information different from the first information, the second information indicating a total number of random access signatures to be divided between a first and second signature set, and a number of random access signatures within the first signature set such that the mobile terminal can determine a number of random access signatures within the second signature set, wherein the first signature set corresponds to a first data size and the second signature set corresponds to a second data size that is different from the first data size; generating, by the mobile terminal, random access signatures of the first and second signature sets according to the one signature root sequence index and the cyclic shift parameter; selecting, by the mobile terminal, a random access signature from either the first signature set or the second signature set based on selection criteria, the selection criteria including the size of data to be transmitted and a radio condition provided by the base station; and transmitting, by the mobile terminal to the base station, the selected random access signature.
