    Abstract: A user equipment (UE) in communication with a base station (BS) is disclosed that includes a receiver that receives Channel State Information (CSI)-Reference Signals (RSs) from the BS, a processor that generates CSI based on the CSI-RS and performs CSI omission, and a transmitter that transmits, to the BS, CSI reports including the CSI where one or more linear combination (LC) coefficients are omitted based on the CSI omission. Further, in the CSI omission, the processor prioritizes LC coefficients based on a predetermined priority rule and the processor also determines the omitted one or more LC coefficients based on the prioritized LC coefficients. In other aspects, a method for a UE and a wireless communication system are disclosed.

    Abstract: A terminal includes a receiving section that receives downlink control information for which cyclic redundancy check (CRC) bits are scrambled with use of a radio network temporary identifier (RNTI) common to one or more terminals, and a control section that controls reception of data associated with a multicast traffic channel (MTCH) with use of a physical downlink shared channel scheduled by the downlink control information in one or more bandwidth parts in a cell. Therefore, it is possible to appropriately control reception of multicast transmission using a physical downlink shared channel.

    Abstract: A user terminal includes: a receiving section that receives configuration information of a search space set; and a control section that controls monitoring of downlink control information (DCI) of a first format other than formats 0_0 and 0_1 used for scheduling of an uplink shared channel and a second format other than formats 1_0 and 1_1 used for scheduling of a downlink shared channel in the search space set configured based on the configuration information. According to an aspect of the present disclosure, monitoring of downlink control information can be appropriately controlled.

    Abstract: A terminal includes: a reception unit configured to receive information related to MCS (Modulation and coding scheme) applied to a terminal-to-terminal direct communication; a control unit configured to determine, in a case where a plurality of MCS tables are configured by the information, which MCS table is to be used, and to determine an MCS from the determined MCS table; and a communication unit configured to perform the terminal-to-terminal direct communication using the determined MCS, wherein the control unit determines an upper limit and a lower limit of available MCSs in the determined MCS table, based on a parameter included in the information.

    Abstract: A terminal includes a reception unit configured to receive information for scheduling a resource used in terminal-to-terminal direct communication, from a base station; and a transmission unit configured to transmit a signal to another terminal, by using the resource. The reception unit is configured to receive, from the another terminal, a response related to a retransmission control corresponding to the signal. The terminal further includes a control unit configured to select either of information including a positive response or information including a negative response, based on the response related to the retransmission control. The transmission unit is configured to transmit the selected information to the base station.
