Abstract: Methods, systems, and devices for wireless communications are described that provide for system information (SI) for access and backhaul. An access node (AN) may provide SI to devices within its cell indicating communication procedure configurations. The AN may provide SI to devices that is specific to whether the communication procedure is an access procedure or a backhaul procedure. The AN may transmit a common master information block (MIB) directing the devices within its cell to a search space in order to receive the remaining SI. The search space may be shared between access devices and backhaul devices or alternatively may be separate between access and backhaul devices. The remaining SI may not be shared between access and backhaul devices. The devices may determine different configurations as defined by the SI from the AN for communications procedures based on whether the procedure is an access procedure or a backhaul procedure.
