Methods and apparatus for data transmission in new radio (nr) inactive state

Abstract

Apparatus and methods are provided for NR data transmission in the INACTIVE state. In one novel aspect, one or more data transmissions are performed in the UE INACTIVE state. The UE initiates the one or more data transmission in the INACTIVE state, restores the UE INACTIVE AS CONTEXT, performs the one or more data transmissions, and stops the data transmission upon detecting one or more preconfigured suspension conditions. In one embodiment, large sized data that cannot be carried by Msg3/MsgA are segmented. The UE multiplexes the BSR and the UL data in one MAC PDU and transmits the MAC PDU in the first UL transmission opportunity. In one embodiment, the UE goes to the CONNECTED state when one or more preconfigured fallback conditions are met. In another embodiment, the UE goes to the IDLE state when one or more preconfigured failure conditions are met.
