201002122 六、發明說明: 【發明所屬之技術領域】 本發明係有關於無線分碼多重存取(CDMA)通信系 統。特別是,本發明係有關於在這類系統中偵測存取叢發。 【先前技術】 x 在無線通信系統中,存取叢發通常係用以增進系統資 訊的存取。這類叢發之例子係用以存取實體隨機存取通道 (PRACH )及實體共用封包通道(pcpcH )之前文 (preamble),誠如第三代合作計畫(3Gpp)寬頻分碼多重存 取(W—CDMA)通信系統所建議。 為增進這些通道之存取,使用者係傳送一前文 (preamble)或簽章(前文(preamble))至基地台。這個基地台 係廣播可利用之訊息碼及能狗傳送前文㈣啦此)之^ 槽。另外,這個使用者亦會傳送傳輸前文之功率 位準’直到這個基地台偵測到這個前文(preamble)、或達到 -最續送功率位準一旦這個基地台偵_—個特定使 用者前文(preamble),一確認(ACK)信號或一負確認(nak ) 信號係傳送至這個使用者,藉以表示這個通道之可利用性。 第1Α及1Β圖係表示利用存取叢發偵測之兩種可能使 用者检度及胞元大小。第1Α圖係表示具有高密度使用者之 -桃元24Α ’諸如:—市區。這個基地台2()係服務使用 者设備(UE) 22〗至2217。為適應大數目之使用者,許多前 文(preamble)訊息碼係用區別使用者。第1B圖係表示具有 少數使用者之大胞元24B。這個基地台2〇係服務使用者設 201002122 備(UE) 22】至223。由於僅僅具有極少使用者,因此大胞 元24B僅需要少數幾個前文(preamble)訊息碼,便足以區別 使^者。然而,來自使用者(UE) 223 (其較為接近這個基 地台)之前文(preamble)傳輸之延遲係遠小於來自使用者 (UE) 2¾ (其位於這個胞元24b周邊)之前文 ,輸_各個使用者係將其傳輸與這個基地台之傳輸之接收 時序同步。因此,在這個胞元24B周邊之使用者傳輸之往 返k遲係运大於較為接近之使用者。因此,第1圖之基地 σ 20亦需要處理這些延遲擴展(印比“)。另外,基於胞元大 J及使用者雄、度,基地台2〇之存取叢發僧測器亦必須有所 不同。 另外,其他胞元參數亦可能有所不同。如第2A圖所 示,這個胞元24A係切割為六個分區26ι至26ό。另外,這 個基地台20亦會利用各個分區私至Μ6之兩個天線^ 至2862 ’藉以利用各個分區26]至批之傳送及接收變異性。 首先’在這個胞元2仏中傳輸之一前物議_可以利用 這些分區26l至266之任何天線元件%至4進㈣測。 有鑑於此,在這種排列中’本發明之主要目的便是提供— 種方法,藉以讓基地台20能夠利用任何天線元件28ll至 ’侧這個胞元24之任何前文㈣紙)訊息碼。相 於第2B圖’這個胞元係沒有分區,且這個基地台% 用單一全方向天線28。 處理這些變動狀況之—種方法係建立硬體,藉以 各種支援天線上、各種可能存取訊息碼之最大可能往返延 201002122 遲。然而’這些參數之最差可能組合之設計卻不太可能會 發生。一般而言,大胞元會利用極少數之存取訊息碼,而 應付'’熱點區域(hot spot area) ”之小胞元卻可能需要較多 訊息碼。另外’分區動作亦會降低使用存取訊息碼之數目。 通常’利用最差狀況之硬體設計可能會在某些實施例中導 致大量未利用之硬體、或是得到僅支援較差狀況之硬體設 計實施例。
有鑑於此,本發明之另一個目的便是提供一種節點B /基地台,藉以有效利用硬體、並彈性地處理這些變動狀 況。 【發明内容】 發訊息碼。 rff * · 。該訊息碼控·係控制各個控彻之輸入訊
