Abstract
A method for wireless communication of a user equipment (UE) in a radio resource control (RRC) Inactive state, the method includes sending, by the UE, an RRC Connection Resume Request message to a base station, and transmitting, by the UE, a packet to the base station using one or more radio resources allocated by the base station, where the base station identifies the UE based on the RRC Connection Resume Request message, which includes a UE ID or a UE-specific preamble. Before the UE enters the RRC Inactive state, the base station sends a pre-configured random access configuration to the UE for transmitting the packet in a subsequent a random access procedure. The pre-configured random access configuration includes at least one of a pre-configured bandwidth part configuration, a plurality of access control parameters, the UE ID, and a time pattern for the random access procedure.
