A UE may receive, from a base station, a first configuration associated with transmitting a low priority UL channel and a second configuration associated with transmitting a high priority UL channel concurrent in time with the low priority UL channel. The UE may cancel the transmission of the low priority UL channel to transmit the high priority UL channel independently, or multiplex the low priority UL channel with the high priority UL channel to transmit both the low priority UL channel and the high priority UL channel together based on a third configuration received from the base station or at least one condition. At least one condition includes a power headroom, a coding rate of high priority data/UCI, or a percentage of resource in high UL channel that is taken by low priority UL transmissions
