Embodiment Construction

[0092] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0093] First, some concepts mentioned in the embodiments of the present invention are described as follows.

[0094] The fifth generation (5Generation, 5G) new air interface (New Radio, NR) system mainly supports three types of services:

[0095] Enhanced Mobile Broadband (eMBB);

[0096] Massive Machine Type Communications (mMTC);

[0097] Ultra-Reliable and Low Latency Communications (URLLC);

[0098] For URLLC, due to its relatively high requirements on delay and reliability, a solution currently proposed by the 3rd Generation Partnership Project (3rd Generation Partnership Project, 3GPP) is to introduce a repeated transmission mechanism, that is, through multiple The path transmits the same Packet Data Convergence Protocol (PDCP) layer Protoc...

Abstract

The invention provides a repeated transmission maintenance method, a terminal and network equipment, and relates to the technical field of communication. The repeated transmission maintenance method is applied to the terminal and comprises the step of maintaining a repeated transmission timer for first repeated transmission carried by a target. According to the repeated transmission maintenance method, the repeated transmission timer is maintained for the first repeated transmission carried by the target, repeated transmission deactivation can be carried out more flexibly through the timer, and the problem that the terminal carries out ping-pong switching between the repeated transmission activation state and the repeated transmission deactivation state can be avoided.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a repeated transmission maintenance method, terminal and network equipment. Background technique [0002] Currently, for packet data convergence protocol (Packet Data Convergence Protocol, PDCP) repeated transmission, it only supports explicit repeated transmission activation / deactivation by the network, the repeated transmission activation / deactivation method is not flexible enough, and may cause the terminal to retransmit activation and deactivation. Do ping-pong switching between repeated transmission deactivation states. Contents of the invention [0003] Embodiments of the present invention provide a repeated transmission maintenance method, terminal and network equipment to solve the problem that the existing repeated transmission activation / deactivation method is not flexible enough, and the terminal may perform ping-pong between repeated transmission acti...
