US 10,567,004 B2 · Method and apparatus for constructing interleaving sequence in a wireless communication system

Abstract

The present disclosure relates to a pre-5th-Generation (5G) or 5G communication system to be provided for supporting higher data rates Beyond 4th-Generation (4G) communication system such as Long Term Evolution (LTE). Method and apparatus for interleaving is provided. The method includes the following steps: constructing a plurality of pseudorandom sequences according to a pre-defined length of an interleaving sequence to be constructed; for each of the constructed pseudorandom sequences, constructing at least one corresponding numerical digit random sequence according to a number of more than two types of numerical values in this pseudorandom sequence; and, for each of the constructed pseudorandom sequences and the at least one corresponding numerical digit random sequence thereof, constructing a corresponding interleaving sequence according to a mapping relation between this pseudorandom sequence and the numerical digit random sequence, so that a plurality of interleaving sequences are allocated and indicated as multiple access signatures.
