METHOD FOR RANDOM ACCESS IN WIRELESS COMMUNICATION SYSTEM, WIRELESS COMMUNICATION SYSTEM, WIRELESS TERMINAL AND BASE STATION MODULE Russian patent published in 2014 - IPC H04W74/08 

FIELD: radio engineering, communication.

SUBSTANCE: invention relates to wireless communication networks and specifically to random access in a wireless communication system. A wireless terminal selects one preamble from a first preamble which is randomly selected by the wireless terminal, used for first random access in accordance with a competitive random access procedure, and a second preamble which is assigned to the wireless terminal by a base station, used for second random access in accordance with a non-competitive random access procedure. Random access is then performed using only the selected preamble, and information is then transmitted during or after random access using the selected preamble, said information being transmitted to a base station during random access using an unselected preamble, wherein said information is used until the process is complete.

EFFECT: selectively performing any random access and efficiently using such resources as signature in random access.
