Title:
QUASI-CO-LOCATION INDICATION METHOD AND APPARATUS
Document Type and Number:
WIPO Patent Application WO/2020/143807
Kind Code:
A1
Abstract:
The present application provides a quasi-co-location indication method and apparatus, relating to the technical field of communications, and used for causing a terminal to learn a quasi-co-location relationship between a plurality of antenna ports of a first reference signal resource. The method comprises: a terminal receives quasi-co-location indication information, said quasi-co-location indication information being used for indicating M antenna port sets corresponding to the first reference signal resource; each antenna port set in the M antenna port sets contains one or a plurality of CDM sets configured by the first reference signal resource; said CDM group contains a plurality of antenna ports; a quasi-co-location relationship is present between any two antenna ports in the same antenna port set; afterward, according to the quasi-co-location indication information, the terminal determines a quasi-co-location relationship between the plurality of antenna ports of the first reference signal resource.
