Claim of US Patent No. 9,749,969

1. A method for multiple-serving-cell connectivity in a UE, comprising:
Step A: receiving a downlink signaling of a first serving cell to obtain a first power control parameter;
Step B: transmitting a first PUCCH signal to the first serving cell with a first power in a first sub frame; and
Step C: transmitting a second PUCCH signal to a second serving cell with a second power in the first sub frame;
wherein the second power is a smaller value between a difference value and a second ideal power, the difference value is obtained
by subtracting the first power from a maximum total transmitting power; the first power is a transmitting power of the first
PUCCH signal without performing a power reduction, and the second ideal power is a transmitting power of the second PUCCH
signal without performing a power reduction; the power is a linear value; the first power control parameter comprises a configuration
parameter of the first power.
