SYNCHRONISATION DE PBCH ET ASPECTS DE CONCEPTION DE CODE POLAIRE IMPLIQUANT UN PREMIER BROUILLAGE DES DONNÉES UTILES ET UN SECOND BROUILLAGE DES DONNÉES CODÉES

摘要

PBCH design may affect timing indication in a wireless network and polar code interleaver design, among other things. Mechanisms may indicate half frame timing though de-modulation reference signal sequence initialization, de-modulation reference signal mapping order, or de-modulation reference signal resource element location. The payload of the PBCH comprises a master information block (MIB), which payload is scrambled and encoded using a polar code. After rate matching and interleaving of the polar codeword, second scrambling is applied and the data is modulated.
