Abstract

Se describen métodos, sistemas y dispositivos para comunicación inalámbrica; recursos de frecuencia dedicados de un canal de acceso aleatorio físico (PRACH) pueden ser designados para saltos de frecuencia grandes y pequeños a fin de facilitar la determinación de compensaciones de temporización para transmisiones del PRACH; por ejemplo, un patrón de salto de frecuencia dentro del canal PRACH que tiene una pluralidad de transmisiones de tono sencillo puede incluir un primer número de saltos asociados con una primera distancia de salto de frecuencia (por ejemplo, saltos de frecuencia grandes), y un segundo número de saltos asociados con una segunda distancia de salto de frecuencia (por ejemplo, saltos de frecuencia pequeños).
