Abstract
Embodiments of the present application provide a method and a device for determining a power control offset for a PUCCH, for resolving the issue in which existing methods for determining a power control offset for a PUCCH are incompatible with new radio communications systems. The method comprises: determining the number of bits, OUCI, of first uplink control information (UCI) required to be transmitted on a PUCCH, and determining the number, NRE, of resource elements (RE) carrying the first UCI in the PUCCH; and determining, according to formula (I), an offset ΔPUCCH_TF,c(i) for calculation of power control of the PUCCH, and g(OUCI/NRE) is a function having OUCI and NRE as variables thereof.

A method for determining a Physical Uplink Control Channel, PUCCH, power control offset, comprising:
- determining a quantity OUCI of bits of first Uplink Control Information, UCI, required to be transmitted on a PUCCH, and determining a quantity NRE of Resource Elements, REs, bearing the first UCI in the PUCCH;
- and
- determining the offset ΔPUCCH_TF,c(i) for PUCCH power control calculation according to a formula ΔPUCCH_TF,c(i)=10 log10 (2g(OUCI/NRE)−1), wherein g(OUCI/NRE) is a linear fitting function with OUCI and NRE being variables, and g(OUCI/NRE) is a*(OUCI/NRE)+b, wherein a and b are tuning coefficients, 1.5≤a≤2.5, and −1≤b≤1.
A terminal, comprising:
- a memory configured to store instructions;
- a processor configured to read the instructions in the memory to:
- determine a quantity OUCI of bits of first Uplink Control Information, UCI, required to be transmitted on a PUCCH, and determine a quantity NRE of Resource Elements, REs, bearing the first UCI in the PUCCH;
- and determine an offset ΔPUCCH_TF,c(i) for PUCCH power control calculation according to a formula ΔPUCCH_TF,c(i)=10 log10 (2g(OUCI/NRE)−1), wherein g(OUCI/NRE) is a linear fitting function with OUCI and NRE being variables, and g(OUCI/NRE) is a*(OUCI/NRE)+b, wherein a and b are tuning coefficients, 1.5≤a≤2.5, and −1≤b≤1.
