Abstract:
A method and apparatus for generating and utilizing spreading sequence codebooks for a symbol-level sequence spreading is disclosed. In one embodiment, a method performed by a wireless communication device, comprising: receiving a first number from a wireless communication node; selecting a first spreading sequence codebook from at least one spreading sequence codebook; selecting a first spreading sequence from the first spreading sequence codebook according to the first number; and spreading data symbols according to the first spreading sequence, wherein the at least one spreading sequence codebook each comprises a plurality of spreading sequences configured based on one entry of a first sequence set after cyclic shifting operation, wherein the first sequence set before cyclic shifting operation is configured based on a second sequence set.
