Summary:PROBLEM TO BE SOLVED: To minimize redundant enhanced uplink (EU) allocation that occurs between a wireless transmit/receive unit (WTRU) 102 and a Node-B 104, and endure damage of EU transmission failures.SOLUTION: The WTRU 102 transmits an allocation request over a UL EU channel 110. In one embodiment, if E-DCH allocation cannot be provided within a predetermined time period, a Node-B sends an acknowledgement message to the WTRU via a DL EU signaling channel 112 without sending E-DCH allocation information. The request is queued in the Node-B and the WTRU refrains from transmitting the same request until after the time period expires or resources become available.SELECTED DRAWING: Figure 1 【課題】ＷＴＲＵ（無線送受信ユニット）１０２とノードＢ１０４との間で発生する冗長なＥＵ（enhanced uplink:向上したアップリンク）割当てを最小にし、ＥＵ送信失敗の障害に耐えること。【解決手段】ＷＴＲＵ１０２は、ＵＬ ＥＵチャネル１１０を介して、割当て要求を送信する。１つ実施形態では、Ｅ−ＤＣＨ割当てが予め定められた時間期間内に提供されなかった場合、ノードＢは、Ｅ−ＤＣＨ割当て情報を送信することなく、ＤＬ ＥＵシグナリングチャネル１１２を介してＷＴＲＵに確認メッセージを送信する。要求はノードＢにおける待ち行列に入れられ、時間期間が満了後まで又はリソースが利用可能となるまで、ＷＴＲＵは同じ要求を送信するのを止める。【選択図】図１
