Terminal, base station, and method for one-shot HARQ-ACK feedback

A terminal according to an aspect of the present disclosure includes a receiving section that performs reception in at least one of a zero power channel state information reference signal (ZP-CSI-RS) resource and a non zero power channel state information reference signal (NZP-CSI-RS) resource configured for a plurality of transmission/reception points, and a control section that controls interference measurement for at least one of a periodic channel state information (CSI) report, a semi-persistent CSI report, and an aperiodic CSI report based on the reception. According to an aspect of the present disclosure, measurement and reporting of CSI for a multi panel/TRP can be appropriately performed.

Terminal, radio communication method, and base station

A user terminal includes: a control section that determines a set of one or more candidate occasions for reception of a downlink shared channel available in a time unit, based on a HARQ-ACK timing value using the time unit shorter than a slot and a format of the time unit; and a transmitting section that transmits a codebook being determined based on the set of the one or more candidate occasions.

Terminal, radio communication method, base station, and system for controlling HARQ-ACK feedback

A terminal includes a communication unit configured to transmit and receive a multi-carrier signal in a frequency band equal to or higher than a predetermined frequency, and a control unit configured to determine a first frame structure of the multi-carrier signal, wherein in the first frame structure, at least one of a subcarrier spacing and a number of resource blocks in a maximum channel bandwidth, a CP (cyclic prefix) ratio, and a time unit or a frequency unit of scheduling is different from a second frame structure of the multi-carrier signal in a frequency band equal to or lower than the predetermined frequency.

A terminal includes a receiving unit configured to receive control information from at least one of another terminal and a base station, and to receive data from the another terminal; a transmitting unit configured to transmit, to the base station, a response relating to a retransmission process corresponding to the data; and a control unit configured to determine the response, based on at least one of the control information received from the another terminal and the control information received from the base station.

A terminal including a receiving unit configured to perform sensing of resource reservation information and resource allocation information transmitted from another terminal by using a sensing window; a control unit configured to determine an available resource set, by identifying a predetermined resource in a resource selection window, based on the resource reservation information and the resource allocation information; and a transmitting unit configured to execute transmission to the another terminal by using a resource selected from the resource set.

In one aspect, a terminal includes a receiver that receives system information including configuration information, which is first information, regarding a Physical Uplink Control Channel (PUCCH), and receives a downlink control information including second information regarding the PUCCH, the downlink control information being for at least one of a message in response to a random access preamble and a contention resolution message in a random access procedure. The terminal also includes a processor that controls a transmission of uplink control information based on the configuration information regarding the PUCCH and the second information regarding the PUCCH. The configuration information regarding the PUCCH is configured commonly with the terminal and other terminals, and the second information regarding the PUCCH is configured individually for the terminal and not configured with the other terminals. In other aspects, a radio communication method, a base station, and a system are also disclosed.
