Embodiment Construction

[0197] The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are only some of the embodiments of the application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0198] figure 1 It is a flowchart of a method for disabling the PDCP packet copy function shown in an exemplary embodiment of the present application. This embodiment is described from the UE side, as shown in figure 1 As shown, the methods for disabling the PDCP packet replication function include:

[0199] In step S101, at least one MAC CE sent by a base station is received, and the MAC CE carries target carrier information.

[0200] In this embodiment, the UE receiving at least...

Abstract

The present disclosure relates to a method and device for disabling and enabling a PDCP packet copy function, a method and device for sending MAC CE, user equipment, a base station, and a computer-readable storage medium. Wherein, the method for closing the packet replication function of the data packet convergence protocol includes: receiving at least one MAC CE sent by the base station, the MAC CE carrying target carrier information; according to the MAC CE, closing the logical channel mapped on the target carrier and opening the PDCP The PDCP packet replication function of the DRB or SRB of the packet replication function. In the embodiments of the present disclosure, by disabling the PDCP packet copy function of the DRB or SRB mapped on the logical channel corresponding to the target carrier and enabling the PDCP packet copy function, the problem that the data packet on the logical channel corresponding to the deactivated target carrier cannot be sent can be solved.

Description

technical field [0001] The present disclosure relates to the field of communication technologies, and in particular, to a method and device for disabling and enabling the replication function of a packet convergence protocol, a method and device for sending media access control control elements, user equipment, a base station, and a computer-readable storage medium. Background technique [0002] At present, the 3rd Generation Partnership Project (3rd Generation Partnership Project, referred to as 3GPP) is carrying out the standardization work on the fifth generation mobile communication technology (5th Generation, referred to as 5G) new radio interface (new radio, referred to as NR), in order to To solve the reliability problem of data packet or signaling packet transmission, 3GPP has adopted a packet duplication scheme at the user plane packet data convergence protocol (PDCP for short) layer. However, since the PDCP layer is located at the top layer of the wireless user pla...
