In operation, the control circuitry selects a Demodulation Reference Signal (DMRS) mapping pattern from among a plurality of DMRS mapping patterns. The DMRS mapping patterns include a first DMRS mapping pattern with first DMRS resource elements to which first DMRSs in a first half of a subframe are mapped and second DMRS resource elements to which second DMRSs in a second half of the subframe are mapped. Also, in operation, the transmitter transmits downlink control information that includes a plurality of bits indicating the selected DMRS mapping pattern."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Communication apparatus and control signal mapping method","description":"A communication apparatus includes control circuitry and a transmitter.
