Description

产生用于高速共享控制信道的用户识别专有扰频码的装置
技术领域
本发明是有关于无线通信系统。特别是，本发明是有关于高速共享控制信道(HS-SCCH)的用户设备识别码(UE ID)专用的扰频序列。
背景技术
宽频码分多址(W-CDMA)通信系统是提出一种高速下行分组存取(HSDPA)方法。这种高速下行分组存取(HSDPA)方法是提供高下行数据速率，藉以支持多媒体服务。
为支持这种高速下行分组存取(HSDPA)方法，高速共享控制信道(HS-SCCH)是加以使用。这些高速共享控制信道(HS-SCCH)是用以发送必要控制信息至用户设备(UE)。各个高速共享控制信道(HS-SCCH)是具有两个部分，其分别称为第一部分(PART I)及第二部分(PART II)。第一部分(PART I)是承载用户设备(UE)需要的时间关键信息。该信息是包括高速物理下行共享控制信道(HS-PDSCH)使用的信道讯息码设定及调制类型，其是承载高速下行分组存取(HSDPA)负担。该信息是支持高速下行分组存取(HSDPA)所必要，因为高速下行分组存取(HSDPA)是使用自适应调制及编码(AMC)方法。
为取得第一部分(PART I)信息，各个高速下行分组存取(HSDPA)用户设备(UE)是监控至多四个高速共享控制信道(HS-SCCH)以取得其信息。一特定用户设备(UE)的信息是利用其用户设备识别码(UE ID)专有的扰频序列，与其它用户设备(UE)进行区别。该用户设备(UE)是利用其用户设备识别码(UE ID)专有的扰频序列，处理各个监控的高速共享控制信道(HS-SCCH)，藉以侦测该用户设备(UE)预期的高速共享控制信道(HS-SCCH)。若该用户设备具有用户设备识别码(UE ID)专有的扰频序列，当该各个监控的高速共享控制信道(HS-SCCH)经由用户设备(UE)处理后，该用户设备(UE)会决定信息是在哪一个高速共享控制信道(HS-SCCH)利用其扰频序列承载。该用户设备(UE)将承载于利用其扰频序列的该高速共享控制信道(HS-SCCH)的第一部分数据解扰频。
直至最近，一10位的用户设备识别码(UE ID)是用以做为该用户设备(UE ID)专有扰频序列的基础。在这个例子中，该用户设备识别码(UEID)是转换为一40位扰频序列。为了将该10位用户设备识别码(UE ID)转换为该40位用户设备识别码(UE ID)专有的扰频序列，该10位用户设备识别码(UE ID)是利用一Reed-Muller方块处理，用以产生一32位讯息码。该产生讯息码的前8个位是重复附加至该32位讯息码的后面，藉以产生一40位讯息码。
虽然该用户设备识别码(UE ID)长度最好能够延伸至16个码片，然而，高速共享控制信道(HS-SCCH)依目前方法是使用一10位用户设备识别码(UE ID)。该用户设备识别码(UE ID)是转换为一40位扰频序列。为了将该10位用户设备识别码(UE ID)转换为该40位扰频序列，该10位用户设备识别码(UE ID)是利用一Reed-Muller方块处理以产生一32位讯息码。另外，该产生讯息码的前8个位是重复附加于该32位讯息码的后面以产生一40位讯息码。
为降低错误侦测的发生，各个用户设备(UE ID)的产生扰频讯息码间最好能够具有完善的区分。因此，扰频讯息码最好能够利用交替方式产生。

具体实施方式
虽然该等较佳实施例是配合本发明的较佳应用详细说明，藉以用于第三代合伙人计划(3GPP)宽频码份多址(W-CDMA)通信系统的高速下行分组存取(HSDPA)方法，本发明亦可以应用于其它类型的码份多址(CDMA)通信系统。图1A及图1B是表示用户设备识别码(UE ID)专有的扰频序列电路。长度L的用户设备识别码(UE ID)XUE是输入至该电路。长度L可以是任何长度，诸如：8位、10位、16位等等。该用户设备识别码(UE ID)XUE＝{XUE1、…、XUEL}是输入至一1/2速率卷积编码器10，如图1A所示。随着该用户设备识别码(UE ID)，额外位(诸如：“0”)亦可以附加至该输入字符串的末端，用以延伸该输入字符串的长度、或该输出字符串的长度。使用一1/2速率卷积编码器10可以在不同用户设备识别码(UE ID)产生的输出字符串间，提供一高标准的讯息码区分。另外，目前的第三代合伙人计划(3GPP)宽频码份多址(W-CDMA)通信系统是利用一1/2速率卷积编码器10以完成一前向误差校正(FEC)技术。因此，该卷积编码用户设备识别码(UE ID)专有的扰频序列并不需要利用额外硬件产生。编码后，基于该输出字符串的长度，一速率匹配阶段12便可以加入刺穿位，用以取得一想要的字符串长度。
图2A及图2B是表示长度16(L＝16)的用户设备识别码(UE ID)讯息码的用户设备识别码(UE ID)专有的扰频序列电路。该16位用户设备识别码(UE ID)，XUE＝{XUE1、…、XUE16}，是输入至一1/2速率卷积编码器14，并将8个位“0”附加至该输入字符串的末端。因此，该输入字符串是XUE1、…、XUE16、0、0、0、0、0、0、0、0。该1/2速率卷积编码器14处理后，该输出讯息码是具有48位长度，即CUE＝{CUE1、...、CUE48}。
为了将该讯息码的长度降低至40位的较佳长度，8个位最好能够刺穿。图2B是表示执行刺穿的速率匹配阶段16。速率匹配阶段16后，该扰频讯息码的有效长度是40位。
图4是表示一简化用户设备，其是利用用户设备识别码(UE ID)专有的扰频讯息码，对一高速共享控制信道(HS-SCCH)进行解扰频动作。该用户设备识别码(UE ID)扰频信息码与该接收高速共享控制信道(HS-SCCH)混合，例如，利用一互斥或是(XOR)门20，用以回复该编码高速共享控制信道(HS-SCCH)数据。
图3是表示一简化基站，其是利用用户设备识别码(UE ID)专有的扰频讯息码，扰频编码数据，用以在该高速共享控制信道(HS-SCCH)上进行传输。该编码数据与用于一特定用户的该用户设备识别码(UE ID)扰频信息码混合，诸如：利用一异或(XOR)门20。该扰频数据是用以产生该高速共享控制信道(HS-SCCH)，藉以传输至该特定用户。
