METHOD FOR UPLINK COMMUNICATION IN MOBILE COMMUNICATION ENVIRONMENT

摘要

PURPOSE: An uplink communication method in a wireless communication environment is provided to grasp which terminal is near what femto base station, thereby grasping location information of the terminal with high accuracy even without a GPS(Global Positioning System) receiver. CONSTITUTION: A macro BS(Base Station) and a femto BS share setup information for MDRA(Multiple Destination Random Access) communication(205). The macro BS broadcasts setup information for an MDRA channel to a terminal(210). The terminal selects an RA(Random Access) code and an uplink RA channel(215). The femto base station senses the RA code(225). The terminal checks the RA code and RA channel information within an RA response(245). The macro base station recognizes the terminal(255).
