1. A user equipment for supporting multiple component carriers through carrier aggregation, comprising:
- a radio frequency (RF) unit, anda processor, coupled to the RF unit, configured to;
control the RF unit to receive control information associated with respective maximum allowed powers for the multiple component carriers;
determine a maximum transmission power PMAX,PUCCH of physical uplink control channel (PUCCH) and a maximum transmission power PMAX,PUSCH of physical uplink shared channel (PUSCH) for a component carrier x among the multiple component carriers; and
determine a transmission power PPUCCH of the PUCCH within the maximum transmission power PMAX,PUCCH and a transmission power PPUSCH of the PUSCH within the maximum transmission power PMAX,PUSCH; and
control the RF unit to transmit the PUCCH at the transmission power PPUCCH and the PUSCH at the transmission power PPUSCH on the component carrier x,wherein the maximum transmission power PMAX,PUCCH is set to be PMAX,x, where PMAX,x is a maximum allowed power for the component carrier x, andwherein the maximum transmission power PMAX,PUCCH is set to be ‘
PMAX,x−
PPUCCH’
, andwherein the multiple component carriers share a maximum transmission power PMAX of the user equipment.
