Abstract

The system's designation involves identifying a time-domain resource unit ux, and determining the redundant version RVx used for system communication on the time-domain resource unit Ux according to the time-domain resource unit Ux, where X is the identifier of the time-domain resource unit, the redundant version RVx satisfies RVx=(Intl(XJ / X2 *(lnt2(x / M) mod K))) mod L, X is a non-negative integer, XI and X2 are non-zero real numbers, M is a positive real number, K and L are positive integers, mod indicates the modulo operation, Intl indicates rounding up or rounding down, and Int2 indicates rounding up or rounding down. The invention relates to a method and apparatus for determining redundant versions of system information.
