Abstract
A terminal according to one aspect of the present disclosure includes a receiving section that receives, by using at least one of downlink control information (DCI) and a Medium Access Control Control Element (MAC CE), an indication indicating disabling or enabling of a transform precoder for a physical downlink shared channel (PUSCH), and a control section that switches, based on the indication, a waveform to be used for the PUSCH. According to one aspect of the present disclosure, it is possible to easily perform switching of a waveform.
Claims4
A terminal comprising:
- a receiver that receives, from downlink control information (DCI), indication indicating whether a transform precoder is disabled or enabled for a physical uplink shared channel (PUSCH);
- and
- a processor that determines, based on the indication, whether the transform precoder is disabled or enabled for the PUSCH,
- wherein a size of each field in the DCI is a larger one of a size of a field in a case where the transform precoder is disabled and a size of a field in a case where the transform precoder is enabled.
A radio communication method for a terminal, comprising:
- receiving, from downlink control information (DCI), indication indicating whether a transform precoder is disabled or enabled for a physical uplink shared channel (PUSCH);
- and
- determining, based on the indication, whether the transform precoder is disabled or enabled for the PUSCH,
- wherein a size of each field in the DCI is a larger one of a size of a field in a case where the transform precoder is disabled and a size of a field in a case where the transform precoder is enabled.
A base station comprising:
- a transmitter that transmits, by downlink control information (DCI), indication indicating whether a transform precoder is disabled or enabled for a physical uplink shared channel (PUSCH);
- and
- a processor that determines, based on the indication, whether the transform precoder is disabled or enabled for the PUSCH,
- wherein a size of each field in the DCI is a larger one of a size of a field in a case where the transform precoder is disabled and a size of a field in a case where the transform precoder is enabled.
A system comprising a terminal and a base station, wherein:
- the terminal comprises:
- a receiver that receives, from downlink control information (DCI), indication indicating whether a transform precoder is disabled or enabled for a physical uplink shared channel (PUSCH);
- and
- a processor that determines, based on the indication, whether the transform precoder is disabled or enabled for the PUSCH, and
- the base station comprises:
- a transmitter that transmits the DCI,
- wherein a size of each field in the DCI is a larger one of a size of a field in a case where the transform precoder is disabled and a size of a field in a case where the transform precoder is enabled.
