Problems solved by technology

[0012] In addition, after an MCG failure occurs in the UE, the UE may receive a reconfiguration message from the MCG. Such a reconfiguration message may be sent to the UE by the base station before receiving the MCG failure information message, so the base station does not consider the UE The current problem of MCG failure

Embodiment 1

[0068] figure 2 is a flow chart showing the method executed by the user equipment according to Embodiment 1 of the present invention.

[0069] Such as figure 2 As shown, in the first embodiment of the present invention, the steps performed by the user equipment UE include: step S201, step S203 and step S205.

[0070] In step S201, when a transmitting PDCP entity (transmitting PDCP entity) submits a PDCP PDU to the lower layer (lower layer), that is, when it is delivered to the RLC layer, if the transmitting PDCP entity is associated with two RLC entities, and the two The RLC entities belong to different cell groups, for example, one belongs to the MCG and the other belongs to the SCG. At this time, it is judged whether the transmission of the primary RLC entity is suspended or not.

[0071] If the transmission of the primary RLC entity is not suspended or not suspended (or simply the primary RLC entity is suspended), then in step S203, the sending PDCP entity submits the P...

Embodiment 2

[0089] image 3 It is a flow chart showing the method executed by the user equipment according to the second embodiment of the present invention.

[0090] Such as image 3 As shown, in the second embodiment of the present invention, the steps performed by the user equipment UE include: step S301, step S303 and step S305.

[0091] In step S301, before transmitting the MCG failure information message, the UE determines whether the primary path is configured as an MCG, or determines whether the primary path is associated with the MCG.

[0092] If the UE determines that the primary path is configured as an MCG, or determines that the primary path is associated with the MCG, then in step S303, the UE performs a change operation as follows: configure the primary path as an SCG, or configure the primary path as associated with an SCG couplet.

[0093] Then, in step S305, the MCG failure information message is delivered to the lower layer for transmission.

[0094] Since the confi...

Embodiment 3

[0100] Figure 4 is a flow chart showing the method executed by the user equipment according to the third embodiment of the present invention.

[0101] Such as Figure 4 As shown, in Embodiment 3 of the present invention, the steps performed by the user equipment UE include: step S401 and step S403.

[0102] After the UE detects MCG failure, or when the UE is performing operations related to MCG failure recovery, the UE may receive an RRC reconfiguration message (RRCReconfiguration). At this point, in step S401, it is determined whether the RRC reconfiguration message is received before the UE generates / sends the MCG failure information message, or after the UE sends the MCG failure information message.

[0103] Then, in step S403, the UE performs a given operation according to whether synchronization information is included in the RRC reconfiguration message and the content of the synchronization information, and sets an RRC connection reconfiguration complete message.

Abstract

The present invention provides a method executed by a user equipment (UE), comprising the following steps that when a sending packet data convergence protocol (PDCP) entity submits a PDCP protocol data unit, i.e., a PDCP PDU, to a radio link control (RLC) layer, whether a main RLC entity of a main RLC entity and an auxiliary RLC entity associated with the sending PDCP entity is suspended or suspended are determined; if it is judged that the transmission of the main RLC entity is not suspended or suspended, the sending PDCP entity submits the PDCP PDU to the main RLC entity; if it is judged that the transmission of the main RLC entity is suspended or suspended, the sending PDCP entity submits the PDCP PDU to the auxiliary RLC entity.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, and more specifically, the present invention relates to a method executed by user equipment and corresponding user equipment. Background technique [0002] With the rapid growth of mobile communication and the great advancement of technology, the world will move towards a fully interconnected network society, that is, anyone or anything can obtain information and share data at any time and anywhere. In order to enhance the mobile broadband service requirements and the communication requirements of massive Internet of Things terminals, the new generation of communication technology (5G) will study the technical enhancements of users under dual connection and even multi-connection (RP-181469New WID on DC and CA enhancements). [0003] Dual connectivity or multi-connection means that a UE working in a connected state establishes a physical path with more than one network node ...
