There is provided a method for transmitting data by a wireless device configured to support WAN communication and V2X communication, the method comprising scheduling a first data transmission to be performed in an N-th subframe, wherein the first transmission uses the WAN communication; scheduling a second data transmission to be performed in an (N−1)-th subframe, wherein the second transmission uses the V2X communication, wherein the (N−1)-th subframe for the second transmission is offset from the N-th subframe by a DFN (Direct Frame Number) offset; determining which one of the first transmission or the second transmission to be dropped, based on a priority between the WAN and V2X communications, wherein the determining is further based on comparison between a length of a last symbol in the (N−1)-th subframe for the second transmission with a length of the DFN offset.
