Claim of US Patent No. 10,893,491

1. A method by a wireless device for determining a maximum output power, the method comprising:obtaining, by the wireless device, a first time resource for transmitting a first signal in a first cell on a first carrier;
obtaining, by the wireless device, 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, determining the maximum output power;
determining a reference time based on at least one of the first time resource and the second time resource;
determining the maximum output power based on the reference time, wherein the reference time is determined as a function of a length of at least one of the first time resource and the second time resource; and 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; and
based on the determined maximum output power, transmitting the first signal in the first cell and the second signal in the second cell.
