Abstract (en)

[origin: WO2019032222A1] A method of wireless communication by a user equipment (UE) without a radio resource control (RRC) connection to a base station includes receiving system information from the base station and transmitting a data communication to the base station over a control plane without establishing an RRC connection with the base station. A UE in an RRC suspended state may transmit a data communication to the base station over a user plane without resuming an RRC connection with the base station. The data communication may comprise data and UE identity information and/or a cause indication. A base station may indicate resources in the system information for the transmission of the data communication information and receive the data communication over the control plane without establishing an RRC connection with the UE or over a user plane without resuming an RRC connection with an RRC suspended UE.
