Preamble allocation method and random access method in mobile communication system |
摘要 |
The present invention relates to a preamble allocation method and a random access method in a mobile communication system. In the present invention, one among preamble resources is allocated to specific mobile stations in advance, before random access. The mobile stations request random access by transmitting a preamble based on the pre-allocated preamble resource to a base station. It is therefore possible to prevent collision caused by the fact that other mobile stations transmit the same preamble.
