The present invention proposes methods and apparatuses for scheduling a transmission. The method implemented at a terminal device, comprising: receiving, from a network device, a scheduling configuration for a device to device, D2D, transmission of the terminal device; receiving, from the network device, an uplink scheduling grant for a cellular uplink transmission in a same time resource overlapping with the D2D transmission; determining a scheduling priority for the D2D transmission relative to the cellular uplink transmission based on at least one of: a first comparison between an associated priority of the scheduling configuration and a first priority threshold, and a transmission restriction; and performing at least one of the D2D transmission and the cellular uplink transmission based on the determined scheduling priority.
