Abstract
Se describen sistemas y métodos para transmisiones de canal de acceso aleatorio, RACH, de dos pasos usando una banda de guarda (por ejemplo, en espectro sin licencia). En una modalidad, un método llevado a cabo por un dispositivo de comunicación inalámbrica comprende obtener una o más configuraciones de canal compartido de enlace ascendente físico (PUSCH) de MsgA para acceso aleatorio de dos pasos, en donde la una o más configuraciones de PUSCH de MsgA comprenden una configuración de PUSCH de MsgA que comprende una ocasión de PUSCH (PO) para acceso aleatorio de dos pasos que se superpone al menos parcialmente a una banda de guarda entre dos subbandas adyacentes. El método comprende además seleccionar la PO que se superponga al menos parcialmente a la banda de guarda entre las dos subbandas adyacentes para una transmisión de MsgA y determinar que la transmisión de MsgA usando la PO seleccionada que se superponga al menos parcialmente a la banda de guarda esté permitida. El método comprende además, luego de determinar que la transmisión de MsgA usando la PO seleccionada es permisible, transmitir la transmisión de MsgA.
