Claim:
1. A method performed by a network node of a radio network, for controlling power of uplink transmissions from a user node configured to switch between a first operating mode and a second operating mode when transmitting radio signals, the method comprising: signaling to the user node a first value of a maximum allowed transmit power to be applied by the user node when operating in the first operating mode using a nominal band of relatively narrow bandwidth, and a second value of the maximum allowed transmit power to be applied by the user node when operating in the second operating mode using a nominal band of relatively wide bandwidth; thereby requiring the user node to use a transmit power not exceeding the first value when transmitting radio signals in the first operating mode, and to use a transmit power not exceeding the second value when transmitting radio signals in the second operating mode such that the user node is instructed to transmit with lower power when operating in the second operating mode as compared to when operating in the first operating mode.
