METHOD OF REFERENCE SIGNALING RESOURCE ALLOCATION FOR CONTROL CHANNEL TRANSMISSION IN WIRELESS COMMUNICATION SYSTEM

摘要

PURPOSE: A reference signaling resource allocation method for the transmission of control channels in a wireless communications system is provided to efficiently utilize limited resources and to reduce loads. CONSTITUTION: A base station sets up user equipment(UE) for an E-CCH(Enhanced Control Channel) setting of the base station(S810). The base station performs a scheduling for the user equipment for each sub-frame(S820). If an E-CCH of the user equipment is set to localized mode based on a DMRS(Demodulation Reference Signal), the base station sets up a DMRS port according to the coupling level of the E-CCH(S830). The base station continues to map E-CCH payload symbols onto allocated E-CCEs(Enhanced Control Channel Element)(S840). The base station transmits an E-CCH scheduled at a sub-frame(S850).
