POWER CONTROL

摘要

Measures for enabling per-carrier power control for inter-band multi-carrier capable devices, such as for example inter-band carrier aggregation capable devices. Such measures may for example comprise calculating a desired cumulative output power value for a combination of at least two uplink carriers of a terminal device, said two uplink carriers operating on different bands, setting an output power value for each of the at least two uplink carriers of the terminal device based on the calculated desired cumulative output power value, and providing, for the terminal device, a power control instruction for the at least two uplink carriers at the terminal device in accordance with the output power values set for the at least two uplink carriers.

1. A method for enabling per-carrier power control on a network side of a cellular system, the method comprising:
calculating a desired cumulative output power value for a combination of at least two uplink carriers of a terminal device, said two uplink carriers operating on different bands, the calculation being based on an intermodulation power equation for the intermodulation power of a specific order intermodulation distortion of the at least two uplink carriers; setting an output power value for each of the at least two uplink carriers of the terminal device based on the calculated desired cumulative output power value; and providing, for the terminal device, a power control instruction for the at least two uplink carriers at the terminal device in accordance with the output power values set for the at least two uplink carriers.
