Abstract
In a terminal, in a slot having allocated thereto both an uplink control channel (PUCCH) and an uplink channel (PUSCH) that includes uplink data, in a case where the difference between the power spectrum density (PSD) of the PUCCH and the PSD of the PUSCH is greater than a threshold value (permitted difference), a control unit drops symbols of the PUSCH in a transmission interval for the PUSCH overlapping with a transmission interval for the PUCCH. A transmission unit transmits at least the PUCCH in the slot.
Claims13
A terminal comprising:
- a receiver, which, in operation, receives information associated with a mode where both an uplink control channel (PUCCH) and an uplink channel (PUSCH) are transmitted in a slot;
- and
- circuitry, which, in operation, controls a transmission of the PUCCH and the PUSCH in the slot based on a difference between a power spectrum density (PSD) of the PUCCH and a PSD of the PUSCH,
- wherein, in a case where a transmission interval for the PUCCH and a portion of a transmission interval for the PUSCH are superposed, the circuitry, in operation, sets a transient period in an interval that does not overlap with the transmission interval for the PUCCH, within the transmission interval for the PUSCH.
A communication method comprising:
- receiving information associated with a mode where both an uplink control channel (PUCCH) and an uplink channel (PUSCH) are transmitted in a slot;
- and
- controlling a transmission of the PUCCH and the PUSCH in the slot based on a difference between a power spectrum density (PSD) of the PUCCH and a PSD of the PUSCH,
- wherein, in a case where a transmission interval for the PUCCH and a portion of a transmission interval for the PUSCH are superposed, the controlling includes setting a transient period in an interval that does not overlap with the transmission interval for the PUCCH, within the transmission interval for the PUSCH.
A terminal comprising:
- a receiver, which, in operation, receives information associated with a mode where both an uplink control channel (PUCCH) and an uplink channel (PUSCH) are transmitted in a slot;
- and
- circuitry, which, in operation,
- controls a transmission of the PUCCH and the PUSCH in the slot based on a difference between a power spectrum density (PSD) of the PUCCH and a PSD of the PUSCH,
- wherein:
- in a case where the difference is greater than a threshold value, the circuitry, in operation, changes a transmission format of the PUCCH, and
- in a case where the transmission format has been changed from a short PUCCH to a long PUCCH, the circuitry, in operation, performs power scaling for the long PUCCH.
