Title:
NTN SYSTEM COMMUNICATION METHOD, DEVICE AND COMPUTER READABLE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2023/077599
Kind Code:
A1
Abstract:
The present disclosure provides an NTN system communication method, a device and a computer readable medium. According to a first aspect of the present disclosure, a communication method in a non-terrestrial network (NTN) is provided. The NTN provides communication with a network device for user equipment (UE) by means of multiple satellite (SATs), the multiple SATs comprising a first SAT, the first SAT being connected to the UE, and the multiple SATs comprising a second SAT, the second SAT being connected to the network device. One or more satellite transmission paths exist between the first SAT and the second SAT, adjacent satellites in each satellite transmission path being connected by means of an inter-satellite link (ISL), and each ISL corresponds to one satellite jump. The method is applied to the first SAT and comprises: sending link delay information to the UE, the link delay information indicating a link delay corresponding to at least one satellite transmission path of the one or more satellite transmission paths.
