Abstract: A communication apparatus comprises: a receiver configured to receive on a physical downlink control channel, from a base station, downlink control information including information for indicating a subgroup identifier of a paging occasion; and a controller configured to calculate a user equipment identity (UE_ID). The controller is configured to calculate the UE_ID by using a first formula on a basis of a fact that the communication apparatus has received first information for indicating a number of subgroups per the paging occasion and second information for a configuration of a UE_ID based subgrouping, and monitor the paging occasion on a basis of the subgroup identifier based on the UE_ID calculated by using the first formula and the subgroup identifier indicated by the information included in the downlink control information, and calculate the UE_ID by using a second formula on a basis of a fact that the communication apparatus has not received the second information, and monitor the paging occasion on a basis of the UE_ID calculated by using the second formula.

Abstract: A terminal includes: a receiving unit which receives, from a core network device, an identifier of a subgroup of a paging occasion to which the terminal belongs, and which receives, from a base station, system information including information for indicating a total number of subgroups of the paging occasion and information for indicating a number of paging occasions corresponding to one Paging Early Indication (PEI) monitoring occasion; and a control unit which performs monitoring of a physical downlink control channel (PDCCH) for first downlink control information (DCI) including a field of a PEI in the PEI monitoring occasion, wherein the control unit performs monitoring of a PDCCH for second DCI in the paging occasion in a case where a value of the PEI indicates the subgroup of the paging occasion to which the terminal belongs; and performs no monitoring of the PDCCH for the second DCI in the paging occasion in a case where the PEI is not detected, or a value of the PEI does not indicate the subgroup of the paging occasion to which the terminal belongs, and a number of bits for the field of the PEI is determined based on the information for indicating the total number of subgroups of the paging occasion and the information for indicating the number of paging occasions corresponding to the one PEI monitoring occasion.

Abstract: A user equipment is configured to communicate with a plurality of networks using a plurality of subscriber identity modules, the user equipment communicates with a base station of a first network. The user equipment performs inter-network measurement for measuring a difference in system frame number and a difference in frame timing between the first network and a second network. The user equipment transmits a radio resource control (RRC) message including a difference measurement result obtained by the inter-network measurement to the base station.

Abstract: A user equipment for communicating with a plurality of networks using a plurality of subscriber identity modules communicates with a base station of a first network. The user equipment acquires a measurement timing configuration indicating a timing at which the user equipment measures a radio condition in a second network. The user equipment transmits a radio resource control message including an information element based on the measurement timing configuration to the base station.

Abstract: A terminal includes: a receiving unit configured to: receive system information including information used for configuring a resource for a reference signal for tracking and receive on a physical downlink control channel, downlink control information used for scheduling of a physical downlink shared channel; and a control unit configured to: use, in an idle state or an inactive state, the resource for the reference signal for tracking, the resource being configured based on the information used for configuring the resource for the reference signal for tracking, and control, in a connected state, reception of the physical downlink shared channel such that the resource configured based on the information used for configuring the resource for the reference signal for tracking is ignored.
