Abstract

Se proporciona una canalización de acceso múltiple por división de espacio que incluye programar una transmisión para dos o más terminales y utilizar diferentes desplazamientos de código que correspondan a diferentes sub-árboles. Las transmisiones pueden programarse en recursos de frecuencia de traslape para periodos de traslape en diferentes recursos espaciales. Los desplazamientos de código piloto proporcionan diferentes firmas piloto para que las transmisiones piloto no se traslapen. Los recurso de frecuencia de traslape pueden traslaparse parcialmente o traslaparse completamente.
