Abstract
The present invention relates to a physical channel allocation method of a mobile communication system and a communication method using the same which is capable of allocating physical channels efficiently for a RACH (Random Access Channel) and a CPCH (Common Packet Channel) having extra up-link scrambling code in a next generation mobile communication system. The communication method of the mobile communication system in accordance with the present invention comprises transmitting a preamble signature code Csig,s generated by using one signature among a plurality of signatures AP#s and a PRACH (Physical Random Access Channel) access preamble code Cpre,n,s generated by using one PRACH preamble scrambling code SC#j among a x-number of PRACH preamble scrambling codes SC#m permitted to the pertinent cell along with an AP (Access Preamble) through a RACH from a terminal to a base station, receiving an AI (Acquisition Indicator) informing a usage of the signature by decoding a signature included in the received AP and the kind of the PRACH scrambling code from the base station by the terminal, and transmitting a message of the terminal to the base station by using a channelizing code determined by the approved signature and PRACH message part scrambling code MSC#m. Accordingly, the terminal and base station can communicate efficiently.
