RANDOM ACCESS METHOD FOR IMPROVING SCRAMBLING EFFICIENCY

摘要

A random access for improving the scrambling performance is provided to perform the scrambling with the identifier of a terminal to which a cell identifier is not assigned, thereby increasing the randomizing performance. A terminal randomly selects a random access preamble in the MAC(Media Access Control) layer of a terminal, and then transmits it to a base station(S601). The second message receiving terminal receives a random access response, in which a random access preamble identifier corresponding to the random access preamble which the receiving terminal transmits is included, from the base station(S602). The terminal transmits the third message to the base station by using the uplink authentication included in the random access response(S603).
