A method of wireless communication comprising: receiving, by a first wireless device of a wireless network from a base station of a wireless network, a schedule for communications over a shared radio frequency spectrum band, the schedule identifying a first set of communication resources allocated by the base station for direct communications between the base station and other wireless devices of the wireless network and a second set of communication resources allocated by the base station for device-to-device, D2D, communications between wireless devices other than the base station that are performed using a communication scheme, wherein the communication scheme comprises a scheduled communication scheme, or a contention-based communication scheme, or a combination thereof; identifying by the first wireless device one or more transmission time intervals of the second set of communication resources; selecting by the first wireless device a transmission time interval from the one or more transmission time intervals; and transmitting by the first wireless device an indication that the selected transmission time interval is reserved by the first wireless device to at least one second wireless device of the wireless network within communication range of the first wireless device to configure the at least one second wireless device to refrain from contending for access during the selected transmission time interval, wherein the indication is transmitted in a discovery interval, the indication comprising an identifier of the first wireless device, a wake-up schedule for the first wireless device, transmission parameters, association parameters, or a combination thereof. receiving, by a first wireless device of a wireless network from a base station of a wireless network, a schedule for communications over a shared radio frequency spectrum band, the schedule identifying a first set of communication resources allocated by the base station for direct communications between the base station and other wireless devices of the wireless network and a second set of communication resources allocated by the base station for device-to-device, D2D, communications between wireless devices other than the base station that are performed using a communication scheme, wherein the communication scheme comprises a scheduled communication scheme, or a contention-based communication scheme, or a combination thereof; identifying by the first wireless device one or more transmission time intervals of the second set of communication resources; selecting by the first wireless device a transmission time interval from the one or more transmission time intervals; and transmitting by the first wireless device an indication that the selected transmission time interval is reserved by the first wireless device to at least one second wireless device of the wireless network within communication range of the first wireless device to configure the at least one second wireless device to refrain from contending for access during the selected transmission time interval, wherein the indication is transmitted in a discovery interval, the indication comprising an identifier of the first wireless device, a wake-up schedule for the first wireless device, transmission parameters, association parameters, or a combination thereof.
