Claim of US Patent No. 10,772,139

1. A terminal device comprising:receiving circuitry configured to receive a message including first configuration related to a Sidelink Direct Discovery;
controlling circuitry configured to determine whether or not the first configuration includes a second configuration used for causing the terminal device to report system information related to a Sidelink Direct Discovery announcement monitoring, and to start, on the basis of a determination that the first configuration includes the second configuration, a timer with a predetermined value being configured, wherein the first configuration including the second configuration includes frequency information indicating a frequency in which the system information is broadcasted; and
transmitting circuitry configured to transmit, to a base station device, configuration information related to a Sidelink Direct Discovery announcement monitoring, based on (a) whether the configuration information related to Sidelink Direct Discovery announcement monitoring is acquired from the system information and (b) whether the timer is running; wherein
the receiving circuitry is configured to receive the system information with use of the frequency indicated by the frequency information.
