Title

(EN) BIT-LEVEL INTERLEAVING WITHIN CODE BLOCKS USING MULTIPLE MODULATION ORDERS ACROSS LAYERS

(FR) ENTRELACEMENT DE NIVEAU BINAIRE DANS DES BLOCS DE CODE À L'AIDE DE MULTIPLES ORDRES DE MODULATION À TRAVERS DES COUCHES

Abstract

(EN) Systems and techniques are provided for wireless communication. For example, a network entity can obtain a plurality of coded bits of a code block (CB) associated with multiple modulation orders, the multiple modulation orders corresponding to a set of transmission layers for the CB. The network entity can determine, based on a set of respective values of the multiple modulation orders, an interleaving configuration indicative of a number of rows for a rectangular interleaver. Using the rectangular interleaver configured with the interleaving configuration, an interleaved bit sequence for the plurality of coded bits can be generated. A plurality of modulated symbols can be output based on the interleaved bit sequence, each modulated symbol mapped to a respective subset of the interleaved bit sequence, and wherein the plurality of modulated symbols includes one or more modulated symbols corresponding to each transmission layer of the set of transmission layers.

(FR) L'invention concerne des systèmes et des techniques destinés aux communications sans fil. Par exemple, une entité de réseau peut obtenir une pluralité de bits codés d'un bloc de code (CB) associé à de multiples ordres de modulation, les multiples ordres de modulation correspondant à un ensemble de couches de transmission pour le CB. L'entité de réseau peut déterminer, sur la base d'un ensemble de valeurs respectives des multiples ordres de modulation, une configuration d'entrelacement indiquant un nombre de rangées pour un entrelaceur rectangulaire. À l'aide de l'entrelaceur rectangulaire configuré avec la configuration d'entrelacement, une séquence de bits entrelacés pour la pluralité de bits codés peut être générée. Une pluralité de symboles modulés peuvent être émis sur la base de la séquence de bits entrelacés, chaque symbole modulé étant mappé sur un sous-ensemble respectif de la séquence de bits entrelacés, et la pluralité de symboles modulés comprenant un ou plusieurs symboles modulés correspondant à chaque couche de transmission de l'ensemble de couches de transmission.
