Abstract

Se describen sistemas, metodologías y dispositivos que pueden facilitar la señalización no coherente de ancho de banda eficiente para transmisiones del canal de control de enlace ascendente; un dispositivo de comunicación (por ejemplo, un dispositivo móvil, estación base) se puede configurar para utilizar o generar un conjunto de palabras clave ortogonales complejas para facilitar la transmisión de información del canal de control utilizando señalización no coherente en una manera eficiente en ancho de banda; un conjunto de palabras clave ortogonales complejas puede comprender un primer subconjunto de palabras clave donde dichas palabras clave tengan una propiedad de correlación cruzada deseable y otro subconjunto de palabras clave que pueda incluir palabras clave expurgadas, donde las palabras clave expurgadas pueden incluir palabras clave descartadas y/o pares de palabras clave que producen una propiedad de correlación cruzada del peor caso; el conjunto y los subconjuntos de palabras clave se determinan con base, por lo menos en parte, en un criterio de palabra clave predefinido; una porción de las palabras clave descartadas se puede utilizar para otros propósitos, tal como decodificación de borrado, estimación de nivel de interferencia, y/u operación del canal de control de modo múltiple.
