Transmit power priority based on cell types in wireless devices
A base station transmits configuration parameters of one or more first cells of a first cell type operating in a first frequency band and one or more second cells of a second cell type operating in a second frequency band. The base station receives a first uplink signal, during a time interval, via the one or more first cells, and a second uplink signal, during the time interval, via the one or more second cells, wherein a transmission power of the first uplink signal is scaled in response to a calculated total transmit power of a plurality of signals comprising the first uplink signal and the second uplink signal exceeding a first value.
