AI Technical Summary
Technical Problem
Existing link re-establishment schemes for PC5 link failures suffer from significant latency issues.
Method used
In the Radio Resource Control (RRC) state of the Uu interface of the first terminal, PC5 RLF information is sent to the network device through the Uu interface, random access, or pre-configured resources, and candidate second terminal information is received for link re-establishment.
Benefits of technology
The link reconstruction process has been simplified, the reconstruction latency has been shortened, and the problem of large latency during PC5 link failure in existing technologies has been solved.

Abstract
The application provides a link re-establishment method, device, terminal and network equipment, wherein the link re-establishment method comprises the following steps: in the case that the PC5 link of the first terminal occurs RLF, according to the RRC state of the Uu interface of the first terminal, the first information is sent to the network equipment by using the first mode; the first information comprises PC5 RLF information; the candidate second terminal information sent by the network equipment is received; PC5 link re-establishment is carried out according to the candidate second terminal information; wherein the first mode comprises any one of the following: through the Uu interface; through the information of random access; through the pre-configured resource. The present scheme can avoid the situation that the link can only be re-established by sending information to the network equipment through the second terminal, simplifies the implementation process, shortens the link re-establishment delay, and well solves the problem that the link re-establishment scheme for PC5 link failure in the prior art has a large delay.
