Abstract

The invention discloses a method for activating a PDCP repetition mechanism of a packet data convergence protocol and a node device, wherein the method for activating the PDCP repetition mechanism of the packet data convergence protocol includes: the second node receives the message sent when the first node configures the PDCP repetition mechanism for the bearer A notification message: after receiving the notification message, the second node changes or determines the activation or deactivation status of the uplink PDCP repetition mechanism of the bearer. The solution of the present invention realizes the activation state of the repetition mechanism of the uplink UL of the bearer while configuring the PDCP repetition mechanism for the bearer.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method for activating a repetition mechanism of a packet data convergence protocol (PDCP) and a node device. Background technique [0002] In the LTE (Long Term Evolution, long-term evolution) system, E-UTRAN (UMTS Terrestrial Radio Access Network, terrestrial radio access network) is composed of multiple eNodeBs (Evolution Node B, evolved Node B), eNodeB and EPC (Evolved Packet Core network, evolved packet core network) are connected through the S1 interface, and eNodeBs are connected through the X2 interface. [0003] In the 5G system, consider introducing a CU (Central Unit, central node) for centralized control and scheduling, RRC (Radio Resource Control, radio resource control) functions and some layer 2 or / and layer 1 functions in the central node CU , other functions of the base station are deployed on a DU (Distribute Unit, distribution node). [0004] The inte...
