Title:
SAMPLE SET GENERATION METHOD AND DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/098259
Kind Code:
A1
Abstract:
A sample set generation method and device. The method comprises: constructing a first basis vector space and a second basis vector space, wherein the first basis vector space comprises O basis vector groups, each basis vector group comprises N1*N2 spatial domain basis vectors, the second basis vector space comprises Nsb frequency domain basis vectors, O is a positive integer, N1 is the number of antenna ports of a first dimension of a transmitting end of channel state information (CSI), N2 is the number of antenna ports of a second dimension of the transmitting end of the CSI, and Nsb represents the number of sub-bands; and constructing a CSI sample set corresponding to each task in a plurality of tasks according to the first basis vector space and the second basis vector space, wherein the CSI sample set corresponding to each task is constructed on the basis of some of spatial domain basis vectors in one basis vector group in the first basis vector space and some of frequency domain basis vectors in the second basis vector space, the CSI sample sets respectively corresponding to the plurality of tasks are used for training a first model, the first model is used for performing training on the basis of a CSI sample set of a target scenario to obtain a second model, and the second model is adapted to the target scenario.
