Embodiment Construction

[0092] In order to make the objectives, technical solutions 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 Radio (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 provided by the 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 protocol data unit (Protocol Data Unit, PDU), which imp...

Abstract

The invention provides a repeated transmission maintenance method, terminal and network equipment, and relates to the technical field of communication. The repeated transmission maintenance method is applied to a terminal, and includes: maintaining a repeated transmission timer for the first repeated transmission of a target bearer. In the above solution, by maintaining the retransmission timer for the first retransmission of the target bearer, the retransmission deactivation can be performed more flexibly through the timer, and the terminal can avoid ping-pong switching between the retransmission activation state and the retransmission deactivation state The problem.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular, to a repeated transmission maintenance method, a terminal and a network device. Background technique [0002] Currently, for Packet Data Convergence Protocol (PDCP) repeated transmission, only network explicit repeated transmission activation / deactivation is supported. The repeated transmission activation / deactivation method is not flexible enough, and may cause the terminal to activate and deactivate repeated transmission. Do ping-pong switching between repeated transmission deactivation states. SUMMARY OF THE INVENTION [0003] Embodiments of the present invention provide a repetitive transmission maintenance method, a terminal, and a network device, so as to solve the problem that the existing repetitive transmission activation / deactivation method is not flexible enough, and the terminal may perform ping-pong between repetitive transmission activation and ...
