Power control of physical channels having different transmission time intervals based on respective power control loops

A wireless device for performing power control of physical channels in a wireless communication system, the wireless device comprising:

• processing circuitry;
• memory containing instructions executable by the processing circuitry whereby the wireless device is operative to:
• determine transmission powers for transmissions on physical channels having different transmission time interval lengths according to respective first and second power control loops, wherein the loops use a common closed-loop power control parameter;
• and
• adjust the common closed-loop power control parameter based on a first indication of a value associated with the first power control loop and a second indication of a value associated with the second power control loop.

A method, in a network node, for performing power control of physical channels in a wireless communication system, comprising the network node:

• transmitting, to a wireless device, a first indication associated with a first power control loop controlling transmit power on a first physical channel having a first transmit time interval (TTI);
• and
• transmitting, to the wireless device, a second indication associated with a second power control loop controlling transmit power on a second physical channel having a second TTI that is different from the first TTI;
• and
• wherein both the first and second indications adjust a common closed-loop power control parameter used by the first and second power control loops.
