Embodiments of the present disclosure provide methods, apparatuses and computer programs for scheduling a transmission. A method implemented at a terminal device comprises 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 ina 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. With embodiments of the disclosure, D2D transmission and cellular uplink transmission from a terminal device can be well coordinated.
