Uplink power control of a terminal device

A first radio access network node for uplink average power control of a terminal device, the first radio access network node comprising:

• processing circuitry;
• and
• a memory comprising instructions which, when executed by the processing circuitry, cause the first radio access network node to:
• estimate average total uplink transmit power for the terminal device;
• determine a dynamic power threshold from the average total uplink transmit power according to a back-off average power control loop, wherein, in the back-off average power control loop, a setpoint value of total average transmission power is compared with a value of the estimated average total uplink transmit power;
• and
• hand over the terminal device from the first radio access network node to a second radio access network node after having estimated the average total uplink transmit power for the terminal device, in order for the second radio access network node to set a value of a power regulating parameter as function of the dynamic power threshold and to provide the value of the power regulating parameter to the terminal device for uplink power control of the terminal device, wherein the value of the power regulating parameter is provided to the terminal device from the second radio access network node upon the terminal device having been handed over from the first radio access network node to the second radio access network node.

A non-transitory machine-readable storage medium comprising computer code which, when run on processing circuitry of a first radio access network node, causes the first radio access network node to perform operations to control uplink average power of a terminal device, the operations comprising:

• estimating average total uplink transmit power for the terminal device;
• determining a dynamic power threshold from the average total uplink transmit power according to a back-off average power control loop, wherein, in the back-off average power control loop, a setpoint value of total average transmission power is compared with a value of the estimated average total uplink transmit power;
• and
• handing over the terminal device from the first radio access network node to a second radio access network node after having estimated the average total uplink transmit power for the terminal device, in order for the second radio access network node to set a value of a power regulating parameter as function of the dynamic power threshold and to provide the value of the power regulating parameter to the terminal device for uplink power control of the terminal device, wherein the value of the power regulating parameter is provided to the terminal device from the second radio access network node upon the terminal device having been handed over from the first radio access network node to the second radio access network node.
