(FR) DISPOSITIF TERMINAL, DISPOSITIF STATION DE BASE ET PROCÉDÉ DE COMMUNICATION
(JA) 端末装置、基地局装置、および、通信方法
Abstract:
(EN) A terminal device that: uses first precoding to transmit a first random access preamble; monitors for a random access response that corresponds to the first random access preamble; increments the value of a counter when the random access response is not successfully received; and, when the value of the counter has been incremented, if the value of the counter has not reached a prescribed value, uses second precoding to transmit a second random access preamble.
(FR) L'invention concerne un dispositif terminal qui : utilise un premier précodage pour transmettre un premier préambule d'accès aléatoire ; surveille une réponse d'accès aléatoire correspondant au premier préambule d'accès aléatoire ; incrémente la valeur d'un compteur lorsque la réponse d'accès aléatoire n'est pas reçue avec succès ; et, lorsque la valeur du compteur a été incrémentée, si la valeur du compteur n'a pas atteint une valeur prescrite, utilise un second précodage pour transmettre un second préambule d'accès aléatoire.
(JA) 端末装置が、第1のプリコーディングを用いて、第1のランダムアクセスプリアンブルを送信し、前記第1のランダムアクセスプリアンブルに対応するランダムアクセス応答をモニタし、前記ランダムアクセス応答の受信に成功しなかった場合に、カウンタの値をインクリメントし、前記カウンタの値がインクリメントされた場合に、前記カウンタの値が所定の値に達していないならば、第2のプリコーディングを用いて、第2のランダムアクセスプリアンブルを送信する。
