Abstract
This application discloses a power control method for an uplink control channel, and an apparatus. Based on a time-frequency resource of a first physical uplink control channel (PUCCH) for carrying first uplink control information (UCI) and a time-frequency resource of a second PUCCH for carrying second UCI overlapping, a terminal sends the first UCI and the second UCI over a third PUCCH by using first power. The first power is determined based on a quantity of bits of the first UCI and/or a quantity of bits of the second UCI, to improve UCI transmission reliability in this scenario.
Claims20
An apparatus, comprising:
- at least one processor configured to:
- determine a first uplink control channel for carrying first uplink control information (UCI) and a second uplink control channel for carrying second UCI;
- and
- based on a time domain resource of the first uplink control channel overlapping a time domain resource of the second uplink control channel, send the first UCI and the second UCI over a third uplink control channel by using a first power;
- wherein:
- the first power is determined based on a quantity of bits of the first UCI and a size of a time-frequency resource for carrying the first UCI via the third uplink control channel and not based on a quantity of bits of the second UCI and a size of a time-frequency resource for carrying the second UCI via the third uplink control channel, wherein a priority of the first UCI is higher than a priority of the second UCI.
A power control method for an uplink control channel, the method comprising:
- determining a first uplink control channel for carrying first uplink control information (UCI) and a second uplink control channel for carrying second UCI;
- and
- based on a time domain resource of the first uplink control channel overlapping a time domain resource of the second uplink control channel, receiving the first UCI and the second UCI from a terminal over a third uplink control channel, wherein transmit power of the third uplink control channel is a first power,
- wherein:
- the first power is determined based on a quantity of bits of the first UCI and a size of a time-frequency resource for carrying the first UCI via the third uplink control channel and not based on a quantity of bits of the second UCI and a size of a time-frequency resource for carrying the second UCI via the third uplink control channel, wherein a priority of the first UCI is higher than a priority of the second UCI.
