Abstract
Provided is a terminal which can suitably transmit an uplink signal. In a terminal (100), a PC parameter control unit (104) sets a first power control parameter corresponding to a first service, when a prescribed condition relating to a control channel used for transmission of uplink signal allocation is met, and sets a second power control parameter corresponding to a second service, when the prescribed condition is not met. A transmission unit (109) transmits the uplink signal by using transmission power calculated by using the first power control parameter or the second power control parameter.
Claims12
A terminal comprising:
- reception circuitry, which, in operation, receives an uplink grant;
- circuitry, which, in operation,
- determines an uplink channel scheduled by the uplink grant utilizes a first service or a second service based on a detection period for detecting the uplink grant, wherein
- the first service is Ultra-Reliable and Low Latency Communications (URLLC),
- in a case where the detection period of the uplink grant is less than or equal to a determined value, the circuitry, in operation, determines the uplink channel scheduled by the uplink grant utilizes the first service, selects a first power control parameter that corresponds to the first service, and calculates a transmission power using the first power control parameter, and
- in a case where the detection period of the uplink grant is greater than the determined value, the circuitry, in operation, determines the uplink channel scheduled by the uplink grant utilizes the second service, selects a second power control parameter that corresponds to the second service and is different from the first power control parameter, and calculates the transmission power using the second power control parameter;
- and
- transmission circuitry, which, in operation, transmits an uplink signal on the uplink channel using the calculated transmission power.

A terminal comprising:
- circuitry, which, in operation,
- generates uplink control information, wherein the uplink control information is included in an uplink signal,
- determines whether or not to perform power boosting for transmission of the uplink signal based on a number of resource elements for the uplink control information, wherein
- in a case where the number of resource elements for the uplink control information is equal to or greater than a determined value, the circuitry, in operation, determines to perform power boosting for the transmission of the uplink signal, selects a first power control parameter that corresponds to a first service, and calculates a transmission power using the first power control parameter,
- in a case where the number of resource elements for the uplink control information is less than the determined value, the circuitry, in operation, determines to not perform power boosting for the transmission of the uplink signal, selects a second power control parameter that corresponds to a second service, and calculates the transmission power using the second power control parameter, wherein the transmission power calculated using the first power control parameter is greater than the transmission power calculated using the second power control parameter, and
- the first service is Ultra-Reliable and Low Latency Communications (URLLC);
- and
- transmission circuitry, which, in operation, transmits the uplink signal using the calculated transmission power.
