摘要： A communication apparatus includes: a receiver configured to receive a system information block from a base station, the system information block including one or a plurality of tracking reference signal (TRS) resource configurations for the communication apparatus in a radio resource control (RRC) idle state or an RRC inactive state. The receiver receives downlink control information (DCI) including a TRS field relating to availability of the one or the plurality of TRS resource configurations, from the base station. The system information block further includes: information for configuring a correspondence between each TRS resource configuration in the one or the plurality of TRS resource configurations and a bit of the TRS information field indicating availability of the TRS resource configuration; and information for configuring a validity duration for the TRS field.

摘要： A user equipment comprises: a radio resource control (RRC) processor configured to perform processing in an RRC layer; and a non-access stratum (NAS) processor configured to perform processing in a NAS layer which is a layer higher than the RRC layer. In a case where the user equipment is in an RRC inactive state with respect to the second network during the communication with the first network, the RRC processor is configured to execute processing of receiving paging addressed to the user equipment from the second network, and notifying the NAS processor that the paging has been received in a case where a transmission-possible notification indicating that information indicating that the communication with the first network is prioritized over the communication with the second network is transmittable is provided from the NAS processor.

摘要： A user equipment according to an aspect of the present disclosure performs communication with a base station in a BWP that is a subset of a total bandwidth of a cell of the base station. The user equipment comprises: a communicator configured to perform the communication using an active BWP to be used for the communication with the base station among a plurality of the BWPs configured in the user equipment; and a controller configured to store a downlink frame timing in a BWP with an SSB when the active BWP is the BWP with the SSB, which is the BWP in which the SSB is transmitted from the base station. The controller is configured to adjust an uplink transmission timing in the active BWP with reference to the stored downlink frame timing when the active BWP is a BWP without the SSB, which is the BWP in which the SSB is not transmitted from the base station.
