發明領域 一修正 本發明一般係關於無線通訊系統,特別是本菸 於此種系統中的點對多點服務。 X月係關 背景 愈來愈希望使用在無線通訊系統中的點對多點服務, 如第1圖所示,在點對多點(PtM),一種服務係自單一點, 如基地台ίο,送至多點,如多重用戶設備12厂123。點對多 點服務的實例為多媒體廣播及群播服務。 在第二代夥伴專案(3GPP )提出系統,可被用於此種 服務的一個經提出頻道為轉送接取頻道(FACH )。該FACH 為一種下行共同傳輸頻道(TrCH),其可由所有使用者接 收。該FACH TrCH藉由將其施用於次要共同控制實體頻道 (S-CCPCH)而被傳播。該S —CCPCH被傳送至所有胞元使用 者。 為限制由該S-CCPCH所使用的無線電資源,該s-CCPCH 資料速度被限制。為說明用途,若高資料速度服務在該 S-CCPCH上被傳輸,則需要使用低資料冗餘來傳輸以達到 高資料速度。因該S-CCPCH係傳輸至整個胞元,其在某服 務質量(QOS )在該胞元周圍足以由使用者接收的功率位 準下傳輸。在此功率位準下傳播高資料速度服務會增加至 其他使用者的介面’減少系統容量,因胞元資源的效率不 足使用,其為非常不欲的。 此外,因該S-CCPCH及FACH的傳播本性,該S-CCPCH及 FACH所需的無線電資源為非常靜態的。因藉由層3發訊技
