摘要： A terminal according to one aspect of the present disclosure includes a control section that determines, in a radio resource control (RRC) connected state, relaxation of at least one of measurement and reporting for radio resource management (RRM) on the basis of a given condition, and a transmitting/receiving section that performs at least one of the measurement and reporting to which the relaxation is applied. According to one aspect of the present disclosure, it is possible to appropriately perform relaxation of measurement/reporting.

摘要： A terminal includes: a transmission unit configured to transmit grouping-triggering information to one or more of other terminals; and a reception unit configured to receive feedback information items from the one or more of the other terminals. The transmission unit shares data with the other terminals and transmits the data to a base station together with the other terminals in a case where the feedback information items include at least one positive response.

摘要： [Problem] The present invention is designed so that, in radio communication systems in which communication is performed using different configurations from those used in existing LTE systems, the load and/or the latency of UEs can be reduced.
[Solution] A user terminal has a receiving section configured to receive a first synchronization signal (PSS), a second synchronization signal (SSS), and a broadcast channel (PBCH), and a control section configured to control, in a predetermined block that is formed by a predetermined number of symbols and a predetermined number of subcarriers, reception of the PSS and the SSS which are located in a first frequency domain, and the PBCH which is located in at least part of a second frequency domain that is broader than the first frequency domain, wherein the PBCH is located in the predetermined block in at least part of a predetermined domain that is neighbor with the SSS in the frequency direction, and the PBCH is not located in a predetermined domain that is neighbor with the PSS in the frequency direction.
