Title:
ADJACENT CELL CONFIGURATION INFORMATION TRANSMISSION METHOD AND SYSTEM, AND COMPUTER-READABLE STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2020/248816
Kind Code:
A1
Abstract:
Provided by the present disclosure are an adjacent cell configuration information transmission method and system, and a computer-readable storage medium. In the adjacent cell configuration information transmission system, when a CSI-RS configuration used for mobility measurement in at least one associated cell is updated, a first base station determines, according to an adjacent cell relationship, a second base station corresponding to an adjacent cell of the cell the CSI-RS configuration of which was updated, wherein both the first base station and the second base station support a new air interface NR, and there is no direct communication interface between the first base station and the second base station; the first base station sends the updated CSI-RS configuration information to a selected first relay node, the first relay node sends the updated CSI-RS configuration information to the second base station, and according to the updated CSI-RS configuration information, the second base station instructs a terminal within a coverage range of the second base station to perform corresponding measurement on the cell associated with the first base station. The present disclosure enables CSI-RS configuration information interaction when there is no direct connection interface between two base stations supporting an NR air interface.
