  • Publication number: 20200107396
    Abstract: A user equipment (UE) and a base station (BS) for a mobile communication system are provided. The UE performs a random access (RA) procedure with the BS in a radio resource control (RRC) idle mode. The UE transmits a preconfigured uplink resource request message to the BS and receives a configuration message indicating a preconfigured uplink resource from the BS. The UE starts a time alignment timer (TAT) which is used for the RRC idle mode in response to the RA procedure. When the UE determines that there exists an uplink message to be transmitted in the RRC idle mode and determines that the current timing advance (TA) value is valid, the UE transmits the uplink message on the preconfigured uplink resource.

    Abstract: A distributed unit and a centralized unit of a base station are provided. The distributed unit receives an RRC connection request message from a user equipment. In response to the RRC connection request message, the distributed unit transmits a base station end (BS-end) connection request message to the control unit, wherein the BS-end connection request message carries a first application protocol identity and a first RRC message. The first RRC message is the RRC connection request message. The control unit transmits a BS-end connection determination message to the distributed unit, wherein the BS-end connection determination message carries the first application protocol identity, a second application protocol identity, a second RRC message, and a piece of SRB information. The distributed unit retrieves the second RRC message from the BS-end connection determination message and transmits the second RRC message to the user equipment.
