Method And Apparatus For Pusch/Pucch Power Scaling Considering Dual Connectivity In Power Limited State

A method of controlling a transmit power by a User Equipment (UE), the method comprising:

• establishing a Radio Resource Control (RRC) connection with a Master evolved NodeB (MeNB) through a primary serving cell, the MeNB being associated with a Master Cell Group (MCG) including one or more serving cells configurable for the UE;
• establishing a connection with a Secondary eNB (SeNB), the SeNB being associated with a Secondary Cell Group (SCG) including one or more serving cells configurable for the UE;
• and
• transmitting a first uplink channel through a serving cell of the MCG and a second uplink channel through a serving cell of the SCG, wherein a first transmit power for the first uplink channel and a second transmit power for the second uplink channel are allocated based on a priority, and the priority is determined based on whether Uplink Control Information (UCI) is included in at least one of the first uplink channel or the second uplink channel and based on a type of a cell group.

A User Equipment (UE), comprising:

• a memory comprising instructions;
• and
• a processor in communications with the memory, wherein the processor is configured to execute the instructions to:
• establish a Radio Resource Control (RRC) connection with a Master evolved NodeB (MeNB) through a primary serving cell, the MeNB being associated with a Master Cell Group (MCG) including one or more serving cells configurable for the UE;
• establish a connection with a Secondary eNB (SeNB), the SeNB being associated with a Secondary Cell Group (SCG) including one or more serving cells configurable for the UE;
• and
• transmit a first uplink channel through a serving cell of the MCG and a second uplink channel through a serving cell of the SCG, wherein a first transmit power for the first uplink channel and a second transit power for the second uplink channel are allocated based on a priority, and the priority is determined based on whether Uplink Control Information (UCI) is included in at least one of the first uplink channel or the second uplink channel and based on a type of a cell group.

A non-transitory computer readable medium having program instructions stored thereon which, when executed by a processor, cause the processor to perform:

• establishing a Radio Resource Control (RRC) connection with a Master evolved NodeB (MeNB) through a primary serving cell, the MeNB being associated with a Master Cell Group (MCG) including one or more serving cells configurable for a User Equipment (UE);
• establishing a connection with a Secondary eNB (SeNB), the SeNB being associated with a Secondary Cell Group (SCG) including one or more serving cells configurable for the UE;
• and
• transmitting a first uplink channel through a serving cell of the MCG and a second uplink channel through a serving cell of the SCG, wherein a first transmit power for the first uplink channel and a second transmit power for the second uplink channel are allocated based on a priority, and the priority is determined based on whether Uplink Control Information (UCI) is included in at least one of the first uplink channel or the second uplink channel and based on a type of a cell group.
