Abstract:
(EN) A terminal (120) transmits a random access signal by use of a first radio resource. A base station (110) receives the random access signal transmitted thereto by use of the first radio resource and identifies, on the basis of the received random access signal, the terminal (120) having transmitted the random access signal. The base station (110) then transmits a response signal that is responsive to the random access signal and that permits the identified terminal (120) to transmit data to the base station (110) by use of a second radio resource different from the first radio resource. The terminal (120) transmits, on the basis of the response signal transmitted from the base station (110), the data to the base station (110) by use of the second radio resource. The base station (110) receives the data transmitted from the terminal (120) by use of the second radio resource.
(FR) Selon l'invention, un terminal (120) transmet un signal d'accès aléatoire au moyen d'une première ressource radio. Une station de base (110) reçoit le signal d'accès aléatoire transmis à celle-ci au moyen de la première ressource radio et identifie, sur la base du signal d'accès aléatoire reçu, le terminal (120) ayant transmis le signal d'accès aléatoire. La station de base (110) transmet ensuite un signal de réponse qui répond au signal d'accès aléatoire et qui permet au terminal identifié (120) de transmettre des données à la station de base (110) au moyen d'une seconde ressource radio différente de la première ressource radio. Le terminal (120) transmet les données à la station de base (110), sur la base du signal de réponse transmis par la station de base (110), au moyen de la seconde ressource radio. La station de base (110) reçoit les données transmises par le terminal (120) au moyen de la seconde ressource radio.
(JA) 端末(120)は、第1の無線リソースによりランダムアクセス信号を送信する。基地局(110)は、第1の無線リソースにより送信された自局へのランダムアクセス信号を受信し、受信したランダムアクセス信号に基づいてランダムアクセス信号を送信した端末(120)を特定する。そして、基地局(110)は、ランダムアクセス信号への応答信号であって、特定した端末(120)が第1の無線リソースと異なる第2の無線リソースにより自局へデータを送信することを許可する応答信号を送信する。端末(120)は、基地局(110)から送信された応答信号に基づいて、第2の無線リソースにより基地局(110)へデータを送信する。基地局(110)は、端末(120)から第2の無線リソースにより送信されたデータを受信する。
