Document Type and Number:
WIPO Patent Application WO/2019/160089
Kind Code:
A1
Abstract:
A base station device provided with: a reception unit which receives a DCI format to be used to schedule a PDSCH, and an upper layer parameter including a parameter subframeAssignment-r15; and a transmission unit which transmits HARQ-ACK corresponding to the PDSCH, wherein, if the duplex mode of a primary cell is FDD, it is determined whether the number of bits in a HARQ Process number field within the DCI format is three or four on the basis of whether or not EN-DC has been set, whether or not the upper layer parameter including the parameter subframeAssignment-r15 has been set, and whether or not the DCI format is mapped to a USS given by a C-RNTI.
