Design of symbol-group-based diffusion scheme

摘要

A method, system and device for the design of a symbol-group based spreading scheme are described. An exemplary method for wireless communication includes transmitting, by a terminal, a first spread signal generated by spreading, by a terminal, a first group of N data symbols using a first set of N sequences, wherein N is a symbol. -group length, L is the spreading length, each of the N sequences of the first set comes from a set of orthogonal spreading sequences comprising L sequences, and each of the L sequences has length L. Another exemplary method for wireless communication includes, by a network node, transmitting, by a network node, an indication of a first set of N sequences, and a first comprising a group of N data symbols spread using the first set of N sequences. and receiving a spread signal.
