METHOD FOR MULTIPLEXING CONTROL SIGNAL AND REFERENCE SIGNAL IN MOBILE COMMUNICATIONS SYSTEM

摘要

A multiplexing method of a control signal and a reference signal in a mobile communication system is provided to code-division-multiplex reference signals of plural MSs(Mobile Stations) with total bandwidths which group control signals of the plural MSs, thereby largely setting CAZAC(Constant Amplitude Zero Auto-Correlation) series length of reference signals for demodulation even though control signals having small transmission bands are transmitted. Control signals of plural MSs are grouped. Reference signals corresponding to the control signals are code-division-multiplexed with the same bandwidths as the grouped control signals. Control resources used for the control signals of the plural MSs are grouped. The reference signals corresponding to the control signals are allocated to reference resources of the same bandwidths as the grouped control resources.
