1. A baseband (BB) processor for a base station configured to, when executing instructions stored in a memory, perform operations comprising:
providing, to a radio frequency (RF) interface for transmission to a user equipment (UE), a service configuration signal including an indication of whether radio resource control (RRC)/non-access stratum (NAS) signaling is allowed to be transmitted by the UE during an INACTIVE state of the UE;
receiving a direct transmission signal from the UE during the INACTIVE state of the UE, wherein the direct transmission signal comprises one or more access control parameters including a Resume Cause;
controlling subsequent direct transmissions from the UE during the INACTIVE state of the UE based on the one or more access control parameters; and
receiving an uplink (UL) transmission as one of the subsequent direct transmissions from the UE during the INACTIVE state of the UE, wherein the UL transmission comprises the RRC/NAS signaling indicated in the service configuration signal.
