Abstract

A user equipment and a method for scheduling a timeline for cancelling uplink (UL) transmission are provided. The method includes: transmitting a low priority UL channel; receiving a first DCI format scheduling a high priority UL channel; and cancelling the transmission of the low priority UL channel and transmitting the high priority UL channel in response to determining that the high priority UL channel overlaps in time with the low priority UL channel.

 transmit a low priority UL channel; 
 receive a first downlink control information (DCI) format scheduling a high priority UL channel; and 
 cancel the transmission of the low priority UL channel and transmit the high priority UL channel in response to determining that the high priority UL channel overlaps in time with the low priority UL channel. 
   
     
     
         8 . The UE of  claim 7 , wherein a starting time of the high priority UL channel and an ending time of the first DCI format are separated by an offset greater than at least one absolute time duration. 
     
     
         9 . The UE of  claim 8 , wherein:
 the at least one absolute time duration includes a first absolute time duration and a second absolute time duration, and   the first absolute time duration is determined based on a radio resource control (RRC) configuration and the second absolute time duration is determined based on UE capability information.
