CA 2680375

A method includes separating resource elements from multiple code blocks into different groups, and decoding the code bits of the resource elements within each group without waiting for a completed reception of a transport block to start decoding. A method includes separating coded bits from multiple code blocks into different groups, and decoding the code blocks containing coded bits within each group. A first CRC is attached to the transport block and a second CRC is attached to at least one code block from the transport block. An improved channel interleaver design method including mapping from coded bits of different code blocks to modulation symbols, and mapping from modulation symbols to time, frequency, and spatial resources, to make sure each code block to get roughly the same level of protection.

L'invention concerne un procédé de séparation d'éléments de ressources de multiples blocs de codes en différents groupes, et de décodage des bits de code des éléments de ressources dans chaque groupe sans attendre la fin de la réception d'un bloc de transport pour commencer le décodage. Le procédé consiste à séparer les bits codés des multiples blocs de codes en différents groupes, puis à décoder les blocs de codes contenant des bits codés dans chaque groupe. Un premier CRC est rattaché au bloc de transport et un second CRC est rattaché à au moins un bloc de code du bloc de transport. L'invention concerne également un procédé d'entrelacement de canaux amélioré consistant à mettre en correspondance des bits codés de différents blocs de codes avec des symboles de modulation, et à mettre en correspondance les symboles de modulation avec des ressources temporelles, de fréquence et spatiales afin de s'assurer que chaque bloc de code bénéficie sensiblement du même niveau de protection.
