TRANSMISSION METHOD AND DEVICE OF CONTROL INFORMATION CAPABLE OF EFFICIENTLY PERFORMING HIGH SPEED/HIGH CAPACITY COMMUNICATION BY INCREASING CHANNEL CAPACITY FOR CONTROL INFORMATION TRANSMISSION

摘要

PURPOSE: A transmission method and a device of control information are provided to improve block error rate(BLER) performance of corresponding channel by optimizing transmission of a control channel configured in a data region.;CONSTITUTION: An E-PDCCH and a PDSCH have different DMRS for optimization of E-PDCCH transmission. A DMRS(1310) corresponding to an E-PDCCH may have a predetermined rank according to the E-PDCCH. A DMRS corresponding to the E-PDCCH may be a DMRS of a rank 1. A DMRS corresponding to a PDSCH may have a different rank from that of the DMRS corresponding to the E-PDCCH. If a rank of a DMRS corresponding to the E-PDCCH is 1, the DMRS may have a higher rank, of which the rank of the DMRS corresponding to the PDSCH greater than 1.;COPYRIGHT KIPO 2013;[Reference numerals] (1310) DRMS for an E-PDCCH; (1320) DRMS for a PDSCH
