Systems and methodologies are described that facilitate employing a hybrid transmission structure in a wireless communication environment. Each transport block (e.g., MAC PDU) can be split into multiple code blocks. Moreover, each of the code blocks can be further divided into two or more code block segments. Further, code block segments from a given code block can be transmitted over a channel during disparate time slots of a subframe. Also, within a given subframe, code block segments corresponding to differing code blocks can be transmitted sequentially in time. Utilization of the foregoing can enable employment of a pipelined decoder structure at a receiver while allowing for optimization of time/frequency diversity.

L'invention concerne des systèmes et des procédés qui facilitent l'utilisation d'une structure de transmission hybride dans un environnement de communication sans fil. Chaque bloc de transport (par exemple, MAC PDU) peut être séparé en de multiples blocs de code. De plus, chacun des blocs de code peut être encore divisé en deux ou plusieurs segments de bloc de code. En outre, des segments de bloc de code provenant d'un bloc de code donné peuvent être transmis sur un canal pendant des intervalles de temps disparates d'une sous-trame. De même, dans une sous-trame donnée, des segments de bloc de code correspondant à des blocs de code différents peuvent être transmis de manière séquentielle dans le temps. L'utilisation de l'invention peut permettre l'emploi d'une structure de décodeur à architecture pipeline au niveau d'un récepteur, tout en permettant une optimisation de la diversité temps/fréquence.
