Title:
METHOD AND DEVICE FOR SEQUENCE DETERMINATION
Document Type and Number:
WIPO Patent Application WO/2019/100739
Kind Code:
A1
Abstract:
Provided in embodiments of the present invention is a sequence determination method. The method provides a sequence group, one sequence group number corresponding to at least two sequences. One of the sequences is for use when mapping consecutive subcarriers; the other sequence is for use when mapping equally spaced subcarriers. The embodiments of the present invention ensure, for sequences of one sequence group, that cross-correlations are as high as possible for transmission signals for which equally spaced mapping is employed and transmission signals for which consecutive mapping is employed of other sequences in the group.
