Abstract
Una disposición de comunicación de acceso múltiple por división de tiempo hibrido/acceso múltiple por división de código que comprende: . una pluralidad de celdas incluyendo una celda en particular y otras celdas: . la celda en particular caracterizada porque comprende: medios para determinar las celdas que interfieren potencialmente entre las demás celdas que interfieren potencialmente con la celda en particular; medios para cada ranura de tiempo, para eliminar esa ranura de tiempo para la comunicación de enlace ascendente, si las primeras de las que potencialmente interfieren usan esa ranura de tiempo para comunicaciones de enlace descendente; medios para asignar una ranura de tiempo a una comunicación de enlace ascendente usando ranuras eliminadas que no sean de enlace ascendente; y medios para asignar una ranura de tiempo a una comunicación de enlace descendente usando ranuras eliminadas que no sean de enlace descendente.
