The base station sets monitoring of a second control channel in the terminal through RRC signaling that is higher-layer control information, the second control channel being transmitted using a second transmit port different from a first transmit port used for transmission of a first control channel. The base station transmits control information for the terminal by mapping the control information to the second control channel. The first transmit port is a transmit port used for transmission of a cell-specific reference signal that is a reference signal common within a cell, and the second transmit port is a transmit port used for transmission of a terminal-specific reference signal that is a reference signal specific to the terminal."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Base station and terminal","description":"In a radio communication system in which a base station and a terminal communicate with each other, the base station is capable of efficiently notifying the terminal of control information.
