Abstract

Se describen sistemas y metodologías que facilitan la asignación de recursos y manejo en un sistema de comunicación inalámbrica. Como se describe en la presente, una estructura de rejilla de recursos puede utilizarse para asignar recursos para usuarios respectivos que corresponden con un canal determinado (por ejemplo, un Canal de Control de Enlace Ascendente Físico (PUCCH). La rejilla de recursos puede construirse utilizando uno o más desplazamientos cíclicos y un conjunto de cuatro cubiertas ortogonales para proporcionar eficiencia mejorada en el uso de recursos. Además, los intervalos en la rejilla de recursos pueden asignarse a usuarios respectivos basándose en índices de usuario mediante una o más funciones de asignación de recursos. Por ejemplo, una función de asignación de recursos puede desfasar una primera cubierta ortogonal en desplazamientos cíclicos en incremento, alternar entre la segunda y cuarta cubiertas ortogonales en desplazamientos cíclicos en incremento con la extenuación de la primera cubierta ortogonal, y desfasar a través de una tercera cubierta ortogonal en desplazamientos cíclicos en incremento con la extenuación de la segunda y cuarta cubiertas ortogonales.
