Title:
WIRELESS COMMUNICATION SYSTEM, WIRELESS COMMUNICATION DEVICE AND WIRELESS COMMUNICATION METHOD, AND COMPUTER PROGRAM
Document Type and Number:
WIPO Patent Application WO2003069925
Kind Code:
B1
Abstract:
A wireless communication system that uses a receiver having a multi-user detection function and a transmitter combining control information and user data and outputting the resultant to realize a wireless communication network that does not require coordination between base stations, for example, when a hand-off is performed or when a cell is overloaded. Upon receiving a transmission signal from a mobile station at the boundary with a neighboring cell, a base station combines control information for hand-off operation control with user data addressed to a mobile station in its own cell and sends the data. In response to this data, a mobile station in the neighboring cell separates the control information by use of the multi-user detection function, detects the signal, and sends a hand-off request to the base station.
