Abstract

Un dispositivo de comunicación inalámbrica (14) (por ejemplo, un equipo de usuario) en un sistema de comunicación inalámbrica (10) está configurado para transmitir una señal de preámbulo de acceso aleatorio (16). El dispositivo de comunicación inalámbrica (14) en particular está configurado para generar una señal de preámbulo de acceso aleatorio (16) que comprende múltiples grupos de símbolos (18), con cada grupo de símbolos (18) en un solo tono durante un recurso de tiempo diferente, de acuerdo con patrón de salto de frecuencia que salta la señal de preámbulo de acceso aleatorio (16) una distancia de frecuencia fija en uno o más grupos de símbolos (18) y salta la señal de preámbulo de acceso aleatorio (16) una distancia de frecuencia pseudoaleatoria en uno o más grupos de símbolos (18). Cada grupo de símbolos (18) comprende uno o más símbolos. El dispositivo de comunicación inalámbrica (14) también está configurado para transmitir la señal de preámbulo de acceso aleatorio (16).
