Systems and Methods to Derive Configured Output Power with Different TTI

The method of claim 4, wherein the reference time comprises:

• a lowest common multiple of a length of the first time resource and a length of the second time resource;
• a highest of the length of the first time resource and the length of the second time resource;
• a fraction of the length of the first time resource or the length of the second time resource;
• a half of the length of the first time resource or the length of the second time resource;
• a fraction of a highest of the length of the first time resource or the length of the second time resource;
• a half of a highest of the length of the first time resource or the length of the second time resource;
• or
• a value configured for at least one of the first time resource and the second time resource.

A wireless device (110) for determining a maximum output power, the wireless device comprising:

• a memory (230) storing instructions;
• and
• a processor (220) configured to execute the instructions to cause the wireless device to:
• obtain a first time resource for transmitting a first signal in a first cell an a first carrier;
• obtain a second time resource for transmitting a second signal in a second cell on a second carrier;
• based on the first time resource and the second time resource, determine the maximum output power;
• based on the determined maximum output power, transmit the first signal to the first cell and the second signal to the second cell.

A method by a network node (115) for determining a maximum output power, the method comprising:

• configuring a wireless device (110) with a first time resource for transmitting a first signal in a first cell on a first carrier;
• configuring the wireless device with a second time resource for transmitting a second signal in a second cell on a second carrier;
• determining a maximum output power based on the first time resource and the second time resource;
• based on the maximum output power, receiving, from the wireless device, at least one of the first signal on the first cell and the second signal on the second cell.

A network node (115) for determining a maximum output power, the network node comprising:

• a memory (530) storing instructions;
• and
• a processor (520) configured to execute the instructions to cause the network, node to:
• configure a wireless device (110) with a first time resource for transmitting a first signal in a first cell on a first carrier;
• configure the wireless device with a second time resource for transmitting a second signal in a second cell on a second carrier,
• determine a maximum output power based on the first time resource and the second time resource;
• based on the maximum output power, receive, from the wireless device, at least one of the first signal on the first cell and the second signal on the second cell.
