A technique for transmitting uplink scheduling grant information (702) from a network node to a wireless device in unlicensed spectrum is described. As to a method aspect of the technique, a listen before talk (LBT) process is performed (202) on each of at least one carrier in the unlicensed spectrum. The uplink scheduling grant information is transmitted (304) on one of the at least one carrier in response to a positive result of the LBT process on the one carrier. The uplink scheduling grant information (702) is indicative of an uplink scheduling grant on multiple carriers in the unlicensed spectrum.
