Prioritization in Radio Access Technology of Uplink Signals
A wireless device receives, from a base station transmits, a first maximum total transmit power (TTP) and a second maximum TTP allowed, respectively, for a first cell group and a second cell group of a second radio access technology (RAT) type different from a first RAT type of the first cell group. A total transmission power, based on a first power, for transmitting first uplink signals via the first cell group and not exceeding the first maximum TTP, and a second power for transmitting second uplink signals via the second cell group and not exceeding the second maximum TTP, exceeds a power value. The second uplink signals and not the first uplink signals are transmitted based on a scheduled transmission of the first uplink signals being dropped based on: the total transmission power exceeding the power value, and the first RAT type having lower priority than the second RAT type.
