Systems and methods of performing power control of a physical channel in a communication system

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

• processing circuitry;
• memory containing instructions executable by the processing circuitry whereby the wireless device is operative to:
• determine a transmission power for a transmission on the physical channel according to a power control loop;
• wherein the loop specifies the transmission power based on at least one parameter, with a value of the at least one parameter being dependent on which of different transmission time interval (TTI) lengths defined as usable on the physical channel is selected for the transmission on the physical channel.

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

• transmitting, to a wireless device, an indication of a value of at least one parameter which is dependent on which of different transmission time interval (TTI) lengths defined as usable on the physical channel is selected for the transmission on the physical channel;
• wherein a transmission power for a transmission by the wireless device on the physical channel is according to a power control loop;
• and
• wherein the power control loop specifies the transmission power based on the parameter.
