Abstract
In a radio communications 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. 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 a control channel different from a first control channel detectable by the terminal regardless of whether the terminal is in connected state or idle state and being detectable by the terminal only in a case where the terminal is in the connected state. The base station transmits control information for the terminal by mapping the control information to the second control channel. The connected state is a state where the terminal holds information concerning a network, and the idle state is a state where the terminal does not hold information concerning a network.

18. A base station for communicating with a terminal in a cell, comprising:
-
a transmission unit configured to transmit control information for the terminal on a second control channel that is a control channel different from a first control channel monitored by the terminal while the terminal is in connected state or idle state, the second control channel being monitored by the terminal only while the terminal is in connected state, wherein the connected state is a state where the terminal holds information concerning a network, and the idle state is a state where the terminal does not hold information concerning a network. - View Dependent Claims (19, 20, 21, 22)

23. A base station for communicating with a terminal in a cell, comprising:
-
a transmission unit configured to transmit control information for the terminal on a first control channel monitored by the terminal while the terminal is in connected state or idle state or on a second control channel monitored by the terminal only while the terminal is in connected state, wherein in a case where the terminal is not configured with monitoring of the second control channel, the control information for the terminal is transmitted on the first control channel, in a case where the terminal is configured with monitoring of the second control channel, the control information for the terminal is transmitted on the first control channel or the second control channel, and the connected state is a state where the terminal holds information concerning a network, and the idle state is a state where the terminal does not hold information concerning a network.

24. A terminal for communicating with a base station in a cell, comprising:
-
a reception unit configured to monitor a second control channel that is a control channel different from a first control channel monitored by the terminal while the terminal is in connected state or idle state, the second control channel being monitored by the terminal only while the terminal is in connected state, and to receive control information for the terminal that is transmitted on the second control channel, wherein the connected state is a state where the terminal holds information concerning a network, and the idle state is a state where the terminal does not hold information concerning a network. - View Dependent Claims (25, 26, 27, 28)

29. A terminal for communicating with a base station in a cell, comprising:
-
a reception unit configured to receive control information for the terminal that is transmitted on a first control channel monitored by the terminal while the terminal is in connected state or idle state or on a second control channel monitored by the terminal only while the terminal is in connected state, wherein in a case where the terminal is not configured with monitoring of the second control channel, the reception unit monitors a candidate of the first control channel, and receives the control information for the terminal, in a case where the terminal is configured with monitoring of the second control channel, the reception unit monitors a candidate of the first control channel and a candidate of the second control channel, and receives the control information for the terminal, and the connected state is a state where the terminal holds information concerning a network, and the idle state is a state where the terminal does not hold information concerning a network.
