Abstract

Un cambio cíclico de una señal de referencia se cuantifica como una combinación de un cambio cíclico específico de celda con un resultado de un salto seudo-aleatorio y una indicación del cambio cíclico específico de celda es radiotransmitido en la celda. En una realización el cambio cíclico es cuantificado como una operación de módulos sobre una suma del cambio cíclico específico de celda, el resultado del salto seudo-aleatorio y el cambio cíclico específico de usuario, en cuyo caso una indicación de cambio cíclico específico de usuario es enviada en una asignación de recurso de enlace ascendente y un usuario envía su señal de referencia cambiada cíclicamente en el recurso de enlace ascendente asignado mediante la asignación de recurso de enlace ascendente. El cambio cíclico también se puede cuantificar de acuerdo con la longitud de la señal de referencia como un cyclic_shift_symbol=(cyclic_shift_value * longitud de la señal de referencia)/12; donde el cyclic_shift_value está entre cero y once y el cyclic_shift_symbol es la cantidad de cambio cíclico dado en los símbolos de señal de referencia.
