The present disclosure provides a method (100) in a terminal device for adapting transmission power among two or more physical uplink channels. The method (100) comprises: identifying (S110) at least one physical uplink channel carrying Ultra-Reliable and Low-Latency Communications (URLLC) related data, from the two or more physical uplink channels; prioritizing (S120) the at least one physical uplink channel over at least one physical uplink channel not carrying URLLC related data of the two or more physical uplink channels; and adapting (S130) transmission power of the two or more physical uplink channels based on the prioritizing, such that the total transmission power of the two or more physical uplink channels does not exceed the maximum transmission power at the terminal device.
