Abstract
A disclosure of the present specification provides a method for executing power control by a user equipment (UE). The method may include the steps of: determining a first amount of power for transmitting a first uplink control information (UCI) by a user equipment (UE) set to have a dual connectivity with a first cell group and a second cell group; and determining a second amount of power for transmitting a second UCI. Herein, when the first UCI includes HARQ-ACK but the second UCI does not include HARQ-ACK, the determination of the first amount of power may have a priority over the determination of the second amount of power.
Claims16
A method for performing a power scaling, the method performed by a user equipment (UE) and comprising:
- determining, by the UE configured with dual connectivity to a master cell group (MCG) and a secondary cell group (SCG), a first power for a first transmission in a first subframe toward the MCG;
- wherein the first power for the first transmission toward the MCG is determined to be less than or equal to a first threshold configured for the MCG,
- determining a second power for a second transmission toward the SCG;
- determining whether a total power related to the MCG and the SCG exceeds a maximum total power,
- scaling down the second power for the second transmission toward the SCG if the exceed is determined and if the first transmission toward the MCG in the first subframe is overlapped with the second transmission toward the SCG.
A user equipment (UE) for performing a power scaling, the UE comprising:
- a reception unit configured with a dual connectivity to a master cell group (MCG) and a secondary cell group (SCG);
- and
- a processor configured to:
- determine a first power for a first transmission in a first subframe toward the MCG;
- wherein the first power for the first transmission toward the MCG is determined to be less than or equal to a first threshold configured for the MCG,
- determine a second power for a second transmission toward the SCG;
- determine whether a total power related to the MCG and the SCG exceeds a maximum total power,
- scale down the second power for the second transmission toward the SCG if the exceed is determined and if the first transmission toward the MCG in the first subframe is overlapped with the second transmission toward the SCG.
