Abstract
The new wireless multimedia environment is coming because of the variety of an user requirement and a traffic increase which we can not accept in the IMT-2000 present systems. To offer the wireless multimedia service the world wireless communication company which included the ITU-R is developing the standard and technique of 4G systems. We analyzed the technique criteria of the 4G wireless communication system in this paper which is based on that of WiBro System. We referred to the technique criteria of the WiBro system and deduced an occupied frequency bandwidth which is the common element of the uplink and downlink system among main wireless communication technique criteria. And we verified this through the simulation. So we proposed the occupied frequency bandwidth for 4G wireless communication in this paper.
