A method for vehicle to everything (V2X) communication in a wireless communication system is provided. The method includes receiving, from a first network, first downlink control information (DCI) for scheduling of a sidelink associated with a second network, wherein the first network is associated with a new radio (NR) network and the second network is associated a long term evolution (LTE) network; and performing, based on the first DCI, a sidelink communication; wherein the first DCI is scrambled by a first radio network temporary identity (RNTI) different from a second RNTI scrambling a second DCI, wherein the second DCI is for scheduling of a sidelink associated with the first network, and wherein the first DCI is used to activate or deactivate a semi-persistently scheduled sidelink transmission.
