Allocating radio resources in mobile communication system
First Claim
Patent Images
1. A method for allocating radio resources in a mobile communication system, the method comprising:
- receiving, by a mobile terminal, a system information block (SIB) including grouping information for a random access procedure;
selecting, by the mobile terminal, at least one preamble group using the SIB according to a size of a message to be transmitted by the mobile terminal;
randomly selecting, by the mobile terminal, at least one preamble within the selected at least one preamble group; and
transmitting, by the mobile terminal, the selected at least one preamble.

Abstract
Transmitting information using a preamble of a Random Access Channel (RACH) in an Evolved Universal mobile Telecommunications System (E-UMTS) is provided. A preamble transmission is used to inform a base station of specific information when a terminal uses a RACH and the base station efficiently allocates radio resources for data transmission to the terminal according to the specific information. Delay time before the terminal transmits data is reduced and unnecessary consumption of radio resources is minimized.
