Abstract

Se describen las técnicas para enviar los datos de tráfico y la información de control en un sistema de comunicación inalámbrica. En un diseño, un transmisor (por ejemplo, un Nodo B o un UE) puede llevar a cabo la formación de haces para enviar los datos de tráfico en M niveles basados en una matriz de precodificación, donde M puede ser uno o mayor. El transmisor puede además llevar a cabo la formación de haces para enviar la información de control en hasta M niveles basados en la misma matriz de precodificación utilizada para los datos de tráfico. El transmisor puede enviar los datos de tráfico con formación de haces en un primer canal físico y puede enviar la información de control con formación de haces en un segundo canal físico. El transmisor puede multiplexar los datos de tráfico con formación de haces y la información de control con formación de haces con el uso de la multiplexión por división de tiempo (TDM) o la multiplexión por división de frecuencia (FDM).
