Embodiment Construction

[0038] According to the background art, it can be known that the technical problem in the prior art is that in the scenario where the cell moves on the ground, the amount of PUR configuration for the UE is very large.

[0039] In order to solve this problem, an embodiment of the present invention provides a data transmission method based on a satellite system. The method includes: receiving PUR configuration information, the wireless resources configured by the PUR configuration information correspond to a group of cells; according to the PUR configuration The message initiates a PUR transfer.

[0040] Through this method, the radio resources of a group of cells can be configured through a single PUR configuration information, thereby effectively reducing the amount of PUR configuration for the UE.

[0041] In order to make the above objects, features and beneficial effects of the present invention more comprehensible, specific embodiments of the present invention will be desc...

Abstract

A data transmission method and device based on a satellite system, a storage medium, a UE, and a base station, the method comprising: receiving PUR configuration information, wherein wireless resources configured by the PUR configuration information correspond to a group of cells; initiating according to the PUR configuration information PUR transmission. Through this method, the PUR of multiple cells can be configured through one PUR configuration information, and there is no need to configure the PUR for the UE cell by cell, which greatly reduces the amount of PUR configuration for the UE.

Description

technical field [0001] The present invention relates to the communication field, in particular to a data transmission method and device, a storage medium, a UE, and a base station based on a satellite system. Background technique [0002] 3GPP RP#86 established the project FS_IoT_NTN to study the support of narrowband Internet of Things (NB-IoT for short) / enhanced Machine-Type Communication (eMTC for short) services in the satellite system. [0003] In the low-to-medium altitude satellite system, when the cell is moving on the ground, the visible time of a beam to the UE is very short. Taking a cell with a height of 1200 km and a satellite diameter of 60 km as an example, the visible time of a single beam to the UE is 11 seconds. A cell consists of a beam or multiple adjacent beams. It takes a relatively long time to complete an uplink (UpLink, UL for short) preconfigured uplink resource (Preconfigured UL Resource, PUR for short) transmission block transmission, which may o...
