TRANSMISSION DEVICE AND A METHOD OF A CONTROL CHANNEL IN A RADIO COMMUNICATION SYSTEM CONSISTING OF A FORMAT OF NEW DOWNLINK CONTROL INFORMATION FOR CAPACITY EXPANSION OF DOWN LINK CONTROL CHANNEL

摘要

PURPOSE: A transmission device and a method of a control channel in a radio communication system are provided to overcome limitation of PDCCH(physical downlink control channel) capacity according to limited radio resource of a control region by DCI(downlink control information) format 1A commonly used for all transmission modes as well as the smallest size of down link control information.;CONSTITUTION: A base station particularly establishes a mixed resource allocation field(S600). The base station generates a mixed DCI including a mixed resource allocation field(S605). The base station adds a CRC(Cyclic Redundancy Check) to the mixed DCI(S610). The base station generates an encoded data(S620). The base station performs a transmission rate matching(S625). The base station generates modulation symbols(S630). The base station maps the modulation symbols to a physical resource element(S635).;COPYRIGHT KIPO 2013;[Reference numerals] (AA) Start; (BB) End; (S600) Particularly establishing a mixed resource allocation field; (S605) Generating a mixed DCI; (S610) Adding a CRC; (S615) Scrambling RNTI; (S620) Generating an encoded data by channel coding; (S625) Matching a transmission rate; (S630) Generating a modulation symbol; (S635) Mapping to a physical resource element
