Method for allocating physical channel of mobile communication system and communication method using the same
First Claim
1. A communication method of a mobile communication system comprising:
- a step in which a terminal carries a preamble signature code (Csig,s) generated by using one of a plurality of signatures (AP#s) and a physical channel (PRACH) access preamble code (Cpre,n,s) of a first up-link generated by using one (SC#i) of ‘
x’
number of physical channel (PRACH) preamble scrambling codes (SC#m) of the first up-link allowed to a corresponding cell, on an access preamble to (AP), and transmits them to a base station through a channel (RACH) of the first up-link;
a step in which the terminal receives an AI from the base station which decodes the signature included in the received AP and the type of the physical channel (PRACH) scrambling code of the first up-link and generates an AI informing whether the signature is available for use, through a channel (AICH#m) of a first down-link; and
a step in which the terminal transmits its message to the base station by using a channelization code that is determined by an acquired signature and the physical channel (PRACH) message part scrambling code (MSC#m) of the first up-link.
