Abstract: A User Equipment (UE) including a wireless transceiver and a controller is provided. The wireless transceiver performs wireless transmission and reception to and from a first cellular station and a second cellular station. The controller continues to send or receive UP data to or from the first cellular station via the wireless transceiver after receiving a handover command message for a handover of the UE from the first cellular station to the second cellular station, and receives a Radio Resource Control (RRC) request message from the second cellular station via the wireless transceiver after sending a handover complete message to the second cellular station. Also, the controller detaches from the first cellular station in response to receiving the RRC request message.

Abstract: Methods and apparatus are provided for UE-triggered handover and early preparation with coexistence of the network-triggered handover. In one novel aspect, the UE is configured early measurement report configuration, receives an early handover command from the serving base station with a handover candidate cell list, monitors handover triggering conditions for each candidate cell on the handover candidate cell list based on a UE-triggered handover configuration and performs the UE-triggered handover to a candidate cell when the corresponding triggering condition is met for the candidate cell. In one embodiment, the UE receives a network-triggered handover command to a target cell, suspends the UE-triggered handover configuration and performs the network-triggered handover to the target cell. The UE discards the UE-triggered handover configuration upon success of the network-triggered handover and resumes the UE-triggered handover configuration upon failure of the network-triggered handover.

Abstract: A User Equipment (UE) including a wireless transceiver and a controller is provided. The wireless transceiver performs wireless transmission and reception to and from a primary cell (Pcell) and a secondary cell (Scell) of a service network. The controller activates duplication of Packet Data Convergence Protocol (PDCP) Packet Data Units (PDUs) for Carrier Aggregation (CA) using a plurality of Radio Link Control (RLC) entities. In response to detecting that an RLC failure of one of the RLC entities, which is not associated with the Pcell, has occurred, the controller sends a Radio Resource Control (RRC) message for reporting the RLC failure to the service network via the wireless transceiver.

Abstract: A wireless transmit receive unit (WTRU) is configured in dual connectivity with a master cell group and a secondary cell group. Uplink (UL) data is sent in an active one of the master cell group and the secondary cell group as an active UL transmission cell group. It is determined whether a UL transmission is to be switched to an alternate one of the master cell group and the secondary cell group and the UL traffic is switched from the active UL transmission cell group to the alternate cell group in response to the determination that the UL transmission is to be switched.

Abstract: A User Equipment (UE) including a wireless transceiver and a controller is provided. The wireless transceiver performs wireless transmission and reception to and from a cell. The controller receives a System Information Block type1 (SIB1) comprising first configuration of a bandwidth size of an initial Downlink (DL) Bandwidth Part (BWP) from the cell via the wireless transceiver, and applies the first configuration for communication with the cell via the wireless transceiver in response to the UE in a Radio Resource Control (RRC) idle or inactive state successfully completing a random access procedure.

Abstract: A User Equipment (UE) including a wireless transceiver and a controller is provided. The wireless transceiver performs wireless transmission and reception to and from a first service network and a second service network. The controller receives a Radio Resource Control (RRC) message comprising a measurement configuration for SFN (System Frame Number) and Frame Timing Difference (SFTD) from the first service network via the wireless transceiver, performs first SFTD measurements between a Primary Cell (PCell) of the first service network and neighbor cells of the second service network via the wireless transceiver in response to the measurement configuration for SFTD indicating the neighbor cells, and sends a result of the first SFTD measurements to the first service network via the wireless transceiver.

Abstract: Aspects of the disclosure provide a mobile terminal including a processing circuit. The processing circuit is configured to obtain a serving cell measurement result of measuring a first set of signal beams from a serving base station, determine a cell-level signal quality parameter based on the serving cell measurement result, and determine whether the cell-level signal quality parameter meets a poor cell-level signal quality condition. The processing circuit is further configured to, in response to a determination that the cell-level signal quality parameter meets the poor cell-level signal quality condition, obtain a neighboring cell measurement result of measuring a second set of signal beams from a neighboring base station, determine whether a measurement event occurs based on the serving cell measurement result and the neighboring cell measurement result, and send a measurement report to the serving base station in response to a determination that the measurement event occurs.

Abstract: Aspects of the disclosure provide methods and apparatus for radio resource control. For example, an apparatus includes transceiver circuitry and processing circuitry. The transceiver circuitry is configured to transmit and receive wireless signals. The processing circuitry is configured to control, when the apparatus is in a power saving mode, the transceiver circuitry to perform a measurement of a potential carrier provided by a network system for communication usage by the apparatus in a connected mode. Then, the processing circuitry provides, before a transition of the apparatus from the power saving mode to the connected mode and via the transceiver circuitry, a result of the measurement of the potential carrier, to the network system. Further, the processing circuitry receives, in the connected mode, carrier configuration information that is determined by the network system based on the result of the measurement of the potential carrier.
