BASE STATION, TERMINAL AND COMMUNICATIONS METHODS

摘要

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 forms a cell, and communicates with the terminal. 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.
