摘要:
A method for receiving orthogonal time, frequency and space (OFTS) basis allocation information by an user equipment in a wireless communication system using an OTFS transmission scheme includes receiving control information including information on an OTFS basis size N from a base station; and receiving data on OTFS bases of a predetermined size indexed according to a pre-defined rule in an N×N OTFS transform matrix on time and frequency domains corresponding to the OTFS basis size, wherein the OTFS bases of the OTFS basis size N is represented into an N×N OTFS transform matrix, wherein in the N×N OTFS transform matrix, a row index represents a cyclic frequency shift index, and a column index represents a cyclic time shift index, wherein the indexing according to the pre-defined rule includes indexing the OTFS bases of the predetermined size in an order such that the cyclic frequency shift and the cyclic time shift in the N×N OTFS transform matrix are maximized.
