Title:
COMMUNICATION METHOD AND DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/067826
Kind Code:
A1
Abstract:
The present application relates to the technical field of communications, and provides a communication method and device. The present application is used to reduce the interference between reference signals of different layers. The method comprises: receiving or sending a first signaling, different values of preset domain segments comprised in the first signaling corresponding to various reference signal combinations, respectively, all reference signals comprised in the various reference signal combinations forming a reference signal set, the reference signal set comprising at least two reference signal groups, any two reference signal groups meeting the following conditions: orthogonal code sequences W(·) of all reference signals in the first reference signal group forming a first sequence group and orthogonal code sequences W(·) of all reference signals in the second reference signal group forming a second sequence group, the first sequence group comprising at least two sequence subgroups, the second sequence group comprising at least two sequence subgroups, and sequences in one sequence subgroup in the first sequence group being orthogonal to sequences in some sequence subgroups in the second sequence group; and generating and sending at least one reference signal.
