Description

第96101427號申請案說明書更正頁 99.8.# 全部模式進行檢測。 又’如第14圖所示,當各行動台使用依各發送區塊或 各存取槽而不同之頻率頻寬發送隨機進接通道時,前置訊 號部檢測處理部1140會對於依各發送區塊或各存取槽而異 之頻率頻寬與編瑪數之積之數的全部模式進行檢測。例 如,發送區塊#1中,行動台以1·25ΜΗζ之頻寬發送隨機進 接通道,發送區塊#2中,行動台以2.5MHz之頻寬發送隨 機進接通道,發送區塊#3中,行動台則以5MHz之頻寬發 送隨機進接通道。藉此’可在各發送區塊或存取槽中,減 少欲檢測之模式數。 又,如第15圖所示,當各行動台組合最小頻寬例如 1.25MHz之集中型FDMA方式與跳頻而發送隨機進接通道 時,複數行動台有時會選擇各異之編碼。此時,如第15圖 所示,前置訊號部檢測處理部1140中,會使用不同之展頻 系列(特徵碼),並輸入已進行多工化之前置訊號訊號。前置 訊號部檢測處理部1140可對於編碼數之模式進行檢測。藉 此,可在各發送區塊或存取槽中,減少欲檢測之模式數。 又,藉由如上述般行動台以跳頻進行發送,接收裝置 2〇〇即使在允許5MHz頻帶之前置訊號時,也可在各發送區 塊利用與1.25MHz頻帶之前置訊號同樣的檢測迴路。又, 此時’也可適用於各行動台併用時間多工(存取槽)而進行發 送之情況。 另外,如第16圖所示,各行動台藉由分散型fdma方 式發送隨機進接通道時,前置訊號部檢測處理部114〇檢測 第96101427號申請案說明書更正頁 99.8.% 編碼數之模式。藉由上述,可在各發送區塊或存取槽,減 少欲檢測之模式數。又’此時,也可適用於各行動台併用 編碼多工 '時間多工(存取槽)而進行發送之情況。 關於L1/L2控制信息部檢測處理部116〇之機能,與前置 訊號部檢測處理部1140之機能一樣。 接著’參照第17圖說明本實施例之無線通訊系統的動 作。 首先’基地台週期性地發送共通引示通道、共通控制 通道至行動台(步驟S1702)。 接著,行動台至少取得以下資訊之其中一者:分配在 包含於共通控制通道之隨機進接通道的次訊框、頻率區塊 的資訊;分散型FDMA方式中之梳齒位置資訊;使用於隨 機進接時之暫時用戶ID的資訊;及顯示發送功率比的資訊 (步驟S1704)。 接著’行動台從共通引示通道之接收時點決定隨機進 接通道之發送時點’從共通引示通道之接收功率決定隨機 進接通道之發送功率與展頻率(步驟S1706)。 然後’行動台發送隨機進接通道(步驟S1708)。 接著’基地台藉由前置訊號部,進行:複數隨機進接 之辨別、檢測;用以控制發送時點控制之接收時點測定, 以及載波頻率之識別(步驟S1710)。 接下來,基地台藉由L1/L2控制信息部,取得:隨機進 接之暫時用戶ID之辨別、對於共有資料通道之預約資訊(步 驟 S1712)。 ^ 1328939 第96101427號申請案說明書更正頁 99.8 ·, 【主要元件符號說明】 100…發送裝置 1020…低雜訊放大器(LNA) 102…D/A轉換器 1040...
