(UTRAN )。UTRAN是被定義為通用行動電信系統 (UMTS )的一部分的無線電存取網路（RAN )，UMTS是第三代夥伴專案（3GPP)支援的第三代（3G)行動電話技術。作為行動通訊全球系統（GSM )技術的後繼的UMTS 目前支援各種空中介面標準，諸如寬頻分碼多工存取 (W-CDMA)、分時-分碼多工存取（TD-CDMA)以及分時 201135272 -同步分碼多工存取（TD-SCDMA )。例如，中國正推行 TD-SCDMA作為以其現有GSM基礎設施作為核心網路的 UTRAN架構中的底層空中介面。UMTS亦支援諸如高速下行鏈路封包資料（HSDPA)之類的增強型3g資料通訊協定，其向相關聯的UMTS網路提供更高的資料傳輸速度和容量》隨著對行動寬頻存取的需求持續增長，研究和開發持續推進UMTS技術以便不僅滿足對行動寬頻存取的增長的需求’而且提高並增強使用者對行動通訊的體驗。基於位置的服務是正被提供以增強使用者體驗的風行服務。然而，為了提供此等服務，希望達成盡可能準確的位置決定。【發明内容】在本案的一態樣中，提供了一種無線通訊的方法。該方法包括基於準則來從複數個鄰點細胞服務區中選擇候選細胞服務區子集，·標識參考細胞服務區；決定與關聯於參考細胞服務區和候選細胞服務區子集兩者的傳播時間相關聯的特性，·及基於所決定的特性來設定位置。在本案的-態樣中，一種用於無線通訊的裝置包括用於基，準則來從複數個鄰點細胞服務區中選擇候選細胞服務區子集的構件’用於標識參考細胞服務區的構件·用於決定與關聯於參考細胞服務區和候選細胞服務區子集兩者的傳播時間相關聯的特性的構件；及用於基於所決定的

&附圖闡述的詳細描述旨在作為各種配置的描述而無意表示可實踐本文中所描述的概念的僅有的配本詳細描述包括特定細節來提供對各種概念的透徹理解然而’對於本領域技藝人士明顯的是，沒有此等特定節亦可實踐此等概念。在一些實例中以方塊圖形式圖不熟知的結構和元件以便避免模糊此類概念。現在轉到圖1 ’其圖示說明電信系統1〇〇的實例的方塊圖本案中通篇提供的各種概念可跨種類繁多的電信系統、網路架構、和通訊標準來實施。舉例而言（但並非限 201135272 定）’圖1中圖示的本案的態樣是參照採用TD-SCDMA標準的UMTS系統來提供的。在此實例中，UMTS系統包括 (無線電存取網路）RAN 102 (例如，UTRAN )，其提供包括電話、視訊、資料、訊息接發、廣播及/或其他服務等的各種無線服務。RAN 102可被劃分成諸如無線電網路子系統（RNS) 107之類的數個rnS，每個RNS由諸如無線電網路控制器（RNC ) 1 〇6之類的RNC來控制。為了清楚起見’僅圖示RNC 106和RNS 107 ;然而’除了 RNC 106 和RNS 107之外，RAN 102還可包括任何數目個rnc和 RNS。RNC 106是除負責其他功能之外，尤其負責指派、重配置、和釋放RNS 107内的無線電資源的裝置。RNC； j 〇6 可經由諸如直接實體連接、虛擬網路或諸如此類的各種類型的介面使用任何適宜的傳輸網路來互連至RAN丨〇2中的其他RNC (未圖示）。由RNS 107覆蓋的地理區域可被劃分成數個細胞服務區，其中無線電收發機裝置服務每個細胞服務區。無線.電收發機裝置在UMTS應用中通常被稱為B節點，但是亦可被本領域技藝人士稱為基地台（BS)、基地收發機站 (BTS )、無線電基地台、無線電收發機、收發機功能、基本服務集（BSS)、擴展服務集（ESS)、存取點（Ap)、或其他某個適宜的術語。為了清楚起見，圖示兩個B節點然而，RNS 107可包括任何數目個無線b節點。b節點108為任何數目個行動裝置提供對核心網路的無線存取點。行動裝置的實例包括蜂巢式電話、智慧型電話、 201135272 對話啟動協定（SIP )電話、膝上型設備、筆記型設備、小筆電、智慧型電腦、個人數位助理（PDA )、衛星無線電、全球定位系統（GPS )設備、多媒體設備、視訊設備、數位音訊播放器（例如，MP3播放器）、相機、遊戲機、或任何其他類似的功能設備。行動裝置在UMTS應用中通常被稱為使用者裝備（UE)，但是亦可被本領域技藝人士稱為行動站（MS)、用戶站、行動單元、用戶單元、無線單元遠端單元'行動設備、無線設備、無線通訊設備、遠端設備、行動用戶站、存取終端（AT)、行動終端、無線終端、遠端終端、手持機、终端、使用者代理、行動用戶端用戶端、或其他某個合適的術語。出於說明目的，圖示個UE

112 和閘道MSC( GMSC) 114來支援電路交換服務。諸如RNC 106之類的一或多個RNC可被連接至MSC 112。MSC 112 是控制撥叫建立、撥叫路由以及UE行動性功能的裝置。 MSC 112亦包括訪客位置暫存器（VLR)(未圖示），其包 201135272 含UE處於MSC 112的覆蓋區内期間與用戶有關的資訊。 GMSC 114提供經由MSC 112的閘道，以供ue存取電路父換網路116。GMSC II4包括歸屬位置暫存器（HLR)(未圖不），HLR包含諸如反映特定使用者已訂閲的服務的詳情的資料之類的用戶資料„HLR亦與包含因用戶而異的認證資料的認證中心（AuC)相關聯。當接收到針對特定ue 的撥叫時，GMSC 114查詢HLR以決定該ue的位置並將撥叫轉發給服務該位置的特定MSC。核心網路104亦用服務GPRS支援節點（SGSN) 118以及閘道GPRS支援節點（GGSN)12()來支援封包資料服務。代表通用封包無線電服務的GpRS被設計成以比標準gsm 電路交換資料服務可用的速度更高的速度來提供封包資料服務。GGSN120為RAN1〇2提供對基於封包的網路122 的連接。基於封包的網路122可以是網際網路、專有資料網或其他某種合適的基於封包的網路^ GGSN 120的主要力能在於向UE 110提供基於封包的網路連通性。資料封包經由SGSN118在GGSN12〇與UEU〇之間傳輸該 SGSN 118在基於封包的域中執行與Msc ιΐ2在電路交換域中執行的功能根本上相同的功能。 UMTS冑中介面是展頻直接序列分碼多工存取 (DS-CDMA)系統。展頻DS_CDMA將使用者資料經由乘以具有稱為碼片的假性隨機位元的序列來擴展到寬得多的頻寬上〇 TD-SCDMA標準基於此類直接序列展頻技術，並且另外要求分時雙卫（TDD)’而非如在眾多FDD模式 201135272 的UMTS/W-CDMA系統中所用的分頻雙工（fdd )。tdd 對B節點108與UE 110之間的上行鏈路（ul)和下行鍵路（DL)兩者使用相同的載波頻率，但是將上行鏈路和下行鏈路傳輸劃分在載波的不同時槽裏。圖2圖示TD-SCDMA載波的訊框結構2〇〇。如所圖示， TD-SCDMA載波具有長度為1〇 ms的訊框202。訊框202 具有兩個5 ms的子訊框204’並且每個子訊框2〇4包括七個時槽TS0到TS6。第一時槽TS0常常被分配用於下行鍵路通訊’而第一時槽TS1常常被分配用於上行鍵路通气。其餘時槽TS2到TS6或可被用於上行鏈路或可被用於下行鍵路’此允許或在上行鏈路方向或在下行鏈路方向上在有較高資料傳輸的時間期間有更大的靈活性。下行鍵路引導頻時槽（DwPTS ) 206、保護期（GP ) 208、以及上行鍵路引導頻時槽（UpPTS) 210 (亦稱為上行鏈路引導頻通道 (UpPCH))位於TS0與TS1之間。每個時槽TS0-TS6可允許多工在最多16個代碼通道上的資料傳輸。代碼通道上的資料傳輸包括由中序信號214分隔開的兩個資料部分 212並且繼以保護期（GP) 216。中序信號214可被用於^ 如通道估計之類的功能，而GP 216可被用於避免短脈衝間干擾。圖3是RAN 300中B節點310與UE 3 50處於通訊的方塊圖’其中RAN 300可以是圖2中的RAN 202, B節點31〇可以是圖2中的B節點208，而UE 350可以是圖2中的 UE 210。在下行鏈路通訊中，發射處理器320可以接收來 201135272 自資料源312的資料和來自控制器/處理器34〇的控制信號。發射處理器320可為資料和控制信號以及參考信號（例如，引導頻信號）提供各種信號處理功能。例如，發射處理器320可提供用於錯誤偵測的循環冗餘檢查（crc)碼、促成前向糾錯（FEC)的編碼和交錯、基於各種調制方案 (例如，二進位移相鍵控（BPSK)、正交移相鍵控（QpsK)、 Μ移相鍵控（M_PSK)、M正交振幅調制（m_qam)及諸如此類）向信號群集的映射、用正交可變擴展因數（〇vsf) 進行的擴[以及與授頻碼的相乘以產su符號。來自通道處理器344的通道估計可被控制器/處理器34〇用來為發射處理器320決定編碼、調制、擴展及/或擾頻方案。可從由UE 350傳送的參考信號或從來自UE35〇的中序信號214 (圖2)中包含的回饋來推導此等通道估計。由發射處理器320產生的符號被提供給發射訊框處理器以建立訊框結構。發射訊框處理胃33〇藉由將符號與來自控制器7處理器340的中序信號214( ® 2)多工來建立此訊框結構’從而得到―系列訊框。此等訊框隨後被提供給發射機332，該發射機332

360,該接收訊框處理器解析每個訊框，並將中序信號214 (圖2)提供給通道處理器3 94並且將資料、控制和參考信號提供給接收處理器370。接收處理器370隨後執行由 B節點310中的發射處理器32〇所執行的處理的逆處理。更具體而言，接收處理器370解擾並解擴展此等符號，並且隨後基於調制方案決定B節點31〇最有可能發射的信號群集點。此等軟判決可以基於由通道處理器394計算出的通道估計。軟判決隨後被解碼和解交錯以恢復資料、控制和參考信號。隨後校驗CRC碼以決定此等訊框是否已被成功解碼。成功地解碼的訊框所攜帶的資料將在隨後被提供給資料槽372,其代表在UEho*/或各種使用者介面（例如，顯不器）中執行的應用程式。成功地解碼的訊框所攜帶的控制信號將被提供給控制器/處理器39〇。當接收機處理器370解碼訊框不成功時，控制器/處理器39〇亦可使用確收（ACK)及/或否定確收（NACK)協定來支援對此等訊框的重傳請求。在上行鏈路中，來自資料源378的資料和來自控制器/ 處理器390的控制信號被提供給發射處理器38〇。資料源 378可代表在UE35〇和各種使用者介面（例如，鍵盤）中執行的應用程式。類似於結合B節點31〇所作的下行鏈路傳送描述的功能，發射處理器38〇提供各種信號處理功能，包括CRC碼、用以促成FEC的編碼和交錯、向信號群集的映射、用0VSF進行的擴展、以及擾頻以產生一系 11 201135272 列符號。由通道處理器394 &B節點31〇所傳送的參考信號或者從由B節點310所傳送的中序信號中包含的回饋推導出的通道估計可被用於選擇合適的編碼、調制、擴展及 /或擾頻方案。由發射處理器380產生的符號將被提供給發射訊框處理器3 82以建立訊框結構。發射訊框處理器382 藉由將符號與來自控制器/處理器39〇的中序信號214 (圖

經由一或多個天線334接收上行鏈路傳輸，並處理該傳輸以恢復調制到載波上的資訊。由接收機335恢復出的資訊被提供給接收訊框處理器336，該接收訊框處理器解析每個訊框’並將中序信號214(圖2)提供給通道處理器344 並且將資料、控制和參考信號提供給接收處理器338。接收處理器33 8執行由UE

350處的操作。例如，控制器/處理器34〇和39〇可提供各種功能，包括時序、週邊介面、電壓調節功率管理和其他控制功能。記憶體342和392的電腦可讀取媒體可分別儲存供B節點310和UE 350用的資料和軟體。B 節點310處的排程器/處理器346可被用於向ue分配資源，以及為UE排程下行鏈路及/或上行鏈路傳輸。圖4是圖示可以是UE

TD-SCDMA標準使用三種方案來提供不使用Gps的情況下對UE的位置決定： 1. 細胞服務區ID:使用當前細胞服務區來近似ue的位置。 2. 受UE辅助的觀察抵達時間.差（〇TD〇A): ue測量若干細胞服務區的抵達時間差並且將測量結果發信號通 14 201135272 知網路，其中該網路執行位置演算。OTDOA使用鄰點細胞服務區與參考細胞服務區之間的SFN-SFN (系統訊框號到系統訊框號）觀察時間差。 3. 基於UE的OTDOA : UE測量若干細胞服務區的抵達時間差並且亦執行位置演算。最後，UE將定位結果發信號通知網路。為了執行基於UE的OTDOA，TD-SCDMA標準規定B 節點（NB )在系統資訊訊息中廣播服務細胞服務區和鄰點細胞服務區的位置資訊。具體而言，系統資訊區塊類型15.5 (SIB-15.5)包括基於UE的OTDOA辅助資料（OTDOA assistance data for UE-Based)資訊元素（IE)。此 IE 指示服務細胞服務區和鄰點細胞服務區的位置資訊》具體而言，包括參考細胞服務區的緯度和經度資訊。在基於UE 的UE定位OTDOA鄰點細胞服務區資訊（UE positioning OTDOA neighbor cell info for UE-based) IE 中，提供鄰點細胞服務區相對於參考細胞服務區的相對位置。然而，除了參考基地台之外，基於UE的定位可能還需要至少三個基地台測量。具體而言，需要三個基地台中的每個基地台與參考基地台之間的觀察時間差。因為UE可能不能從TD-SCDMA網路中的足夠數目個基地台接收到有效信號，所以在本案的一態樣中，多模TD-SCDMA UE 能夠利用CDMA lx網路來改善信號偵測並執行用於UE位置演算的其他測量。當TD-SCDMA網路中沒有足夠的具有良好信號品質的 15 201135272 基地台時，可以使用 CDMA lx BS 中的基地台以及 TD-SCDMA網路中的基地台的觀察時間差來估計UE位置。 3GPP和 3GPP2標準中的系統要求是TD-SCDMA和 CDMA lx系統是同步的。具體而言，長度為 10 ms的 TD-SCDMA與長度為20 ms的CDMA訊框是對齊的。此等訊框亦與GPS時間對齊。在CDMA lx系統中，服務基地台（BS )的位置在系統參數訊息（SPM )中指示。在本案的一個態樣中，對於多模終端而言，藉由作為 TD-SCDMA網路的補充還搜索和測量CDMA lx網路的方式來支援UE位置估計。因此，多模（TD-SCDMA和CDMA lx)终端不但可以搜尋TD-SCDMA基地台信號，亦可以搜尋CDMA lx基地台信號以改善UE定位程序的可用性和準確性。參照圖6並進一步參照圖7，將描述UE位置決定程序 600，在此在步驟602中，選取UE 702的射程内的稱為鄰點細胞服務區的細胞服務區（基地台）諸如細胞服務區 710、712、720和722之類以供納入候選基地台群組。在本案的一個態樣中，信號干擾加雜訊比被選取作為選擇優選候選基地台的度量，以使得： •可以藉由測量主共用控制實體通道（P-CCPCH )的信號干擾比（SIR)來決定候選TD-SCDMA NB，該SIR由以 dB計的S_td(i)表示。假定索引i參引具有可用信號測量的每個可用TD-SCDMA NB。 16 201135272 •可以藉由測量CDMA lx基地台的引導頻信號干擾雜訊比（SINR)來決定候選CDMA lx基地台，該SINR由以 dB計的S_cd(j)表示。假定索引j參引具有可用信號測量的每個可用CDMA BS。因此，多模終端就能夠為基於UE的定位決定程序選取 TD-SCDMA和CDMA lx網路中最佳的Μ個基地台，其中。為了針對不同的網路技術進行調整，在選擇基地台時使用以下調整： • TD-SCDMANB : S_td(i)-Offset_td • CDMA lx BS ： S_cd(j)-Offset_cd 以上偏移或調整值即Offset_td、Offset_cd (以dB計）對於特定的無線電存取技術（RAT )而言是恆定的。在步驟604中，在本案的一個態樣中，來自以上信號測量規程中的候選細胞服務區的最強的TD-SCDMA B節點將被選取作為參考細胞服務區，該參考細胞服務區被標識為TD參考細胞服務區71 0。在步驟606中，UE測量從每個鄰點細胞服務區 (TD-SCDMA或CDMA，諸如TD鄰點細胞服務區712、 CDMAlx鄰點細胞服務區B 720、和CDMAlx鄰點細胞服務區C 722 )至參考細胞服務區（TD參考細胞服務區7 1 0 ) 的時間差。TD-SCDMA網路中的觀察時間差被定義為系統訊框號（SFN-SFN)觀察時間差。即，UE 702能夠測量鄰點細胞服務區的收到訊框邊界相對於參考細胞服務區的 17 201135272 收到訊框邊界的延遲。SFN-SFN觀察時間差被定義為 TD-SCDMA/CDMA lx鄰點細胞服務區的訊框邊界相對於參考細胞服務區的訊框邊界的抵達時間差。若偵測到鄰點細胞服務區的訊框邊界是在參考細胞服務區的訊框邊界之後接收到的，則SFN-SFN觀察時間差為正。可以類似地測量CDMA lx相對於TD-SCDMA參考細胞服務區7 1 0的觀察時間差，區別僅在於每CDMA訊框就有兩個TD-SCDMA訊框並且因此使用最接近的TD-SCDMA 訊框邊界。圖5包括訊框時序圖500,其圖示了決定CDMA lx訊框邊界與TD-SCDMA訊框邊界之差的概念。在以上規程中，對諸如TD鄰點細胞服務區A712、CDMAlx細胞服務區B 720和CDMAlx鄰點細胞服務區C 722之類的至少三個鄰點基地台（TD-S*CDMANB或CDMABS)執行相對於TD-SCDMA參考細胞服務區710的時間差測量。在步驟 608 中，UE 702 從 SIB-15.5 擷取 TD-SCDMA 參考細胞服務區710的位置以及諸如TD-SCDMA網路中的 TD鄰點細胞服務區A 712之類的鄰點細胞服務區的位置。對於諸如CDMAlx鄰點細胞服務區B 720和CDMAlx 鄰點細胞服務區C 722之類的CDMA lx鄰點細胞服務區而言，UE 702需要擷取此等鄰點細胞服務區中的每個鄰點細胞服務區的SPM。在步驟610中，UE 702利用此等基地台的觀察時間差和位置來估計UE位置。圖8是圖示.根據本案的一個態樣在進行無線通訊時所執 18 201135272 行的示例性方塊的功能方塊圖8〇〇。方塊8〇2包括基於準則來從複數個鄰點細胞服務區中選擇候選細胞服務區子集。另外，方塊804包括標識參考細胞服務區。另外，方塊806包括決定與關聯於參考細胞服務區和候選細胞服務區子集兩者的傳播時間相關聯的特性。不僅如此，方塊8〇8 還包括基於所決定的特性來設定位置。在種配置中，用於無線通訊的裝置350包括用於基於準則來從複數個鄰點細胞服務區中選擇候選細胞服務區子集的構件；用於標識參考細胞服務區的構件；用於決定與關聯於參考細胞服務區和候選細胞服務區子集兩者的傳播時間相關聯的特性的構件；及用於基於所決定的特性來认疋位置的構件。在一個態樣中，前述構件可以是配置成執行由則述構件敍述的功能的處理器。在另一態樣中’前述構件可以是配置成執行由前述構件敍述的功能的模組或任何裝置。已參照TD-SCDMA系統提供了電信系統的若干態樣。如本領域技藝人士將容易領會，貫穿本案描述的各種態樣可擴展到其他電㈣統、網路架構和通訊標準。作為實例，各種態樣可擴展到其他麗TS系統，諸如W-CDMA、高速

An example of such a network is the Universal Terrestrial Radio Access Network (UTRAN). UTRAN is a Radio Access Network (RAN) defined as part of the Universal Mobile Telecommunications System (UMTS), a third generation (3G) mobile phone technology supported by the Third Generation Partnership Project (3GPP). As a successor to the Global System for Mobile Communications (GSM) technology, UMTS currently supports a variety of null interfacing standards such as Wideband Code Division Multiple Access (W-CDMA), Time Division-Code Division Multiple Access (TD-CDMA), and Time 201135272 - Synchronous code division multiplex access (TD-SCDMA). For example, China is pursuing TD-SCDMA as the underlying air intermediary in the UTRAN architecture with its existing GSM infrastructure as its core network. UMTS also supports enhanced 3G data protocols such as High Speed Downlink Packet Data (HSDPA), which provides higher data transfer speeds and capacities to associated UMTS networks.

These concepts can also be practiced in specific sections. Structures and elements that are not well known are shown in block diagram form in some instances in order to avoid obscuring such concepts. Turning now to Figure 1, a block diagram illustrating an example of a telecommunications system will be implemented across a wide variety of telecommunications systems, network architectures, and communication standards. For example (but not limited to 201135272) the aspect of the present invention illustrated in Figure 1 is provided with reference to a UMTS system employing the TD-SCDMA standard. In this example, the UMTS system includes a (Radio Access Network) RAN 102 (e.g., UTRAN) that provides various wireless services including telephony, video, data, messaging, broadcast, and/or other services. The RAN 102 can be divided into a number of rnSs, such as a Radio Network Subsystem (RNS) 107, each RNS being controlled by an RNC such as Radio Network Controller (RNC) 1 〇6. For the sake of clarity 'only RNC 106 and RNS 107 are illustrated; however 'in addition to RNC 106 and RNS 107, RAN 102 may also include any number of rnc and RNS. The RNC 106 is a device that is specifically responsible for assigning, reconfiguring, and releasing radio resources within the RNS 107 in addition to other functions. RNC; j 〇6 may be interconnected to other RNCs (not shown) in RAN丨〇2 via any suitable transport network via various types of interfaces, such as direct physical connections, virtual networks, or the like. The geographic area covered by the RNS 107 can be divided into a number of cell service areas, with the radio transceiver device serving each cell service area. A wireless transceiver device is commonly referred to as a Node B in UMTS applications, but can also be referred to by those skilled in the art as a base station (BS), a base transceiver station (BTS), a radio base station, a radio transceiver, and a transceiver. Machine function, basic service set (BSS), extended service set (ESS), access point (Ap), or some other suitable term. For clarity, two Node Bs are illustrated. However, the RNS 107 can include any number of wireless b-nodes. Node 108 provides wireless access points to the core network for any number of mobile devices. Examples of mobile devices include cellular phones, smart phones, 201135272 Session Initiation Protocol (SIP) phones, laptops, notebooks, laptops, smart computers, personal digital assistants (PDAs), satellite radios, global A positioning system (GPS) device, a multimedia device, a video device, a digital audio player (eg, an MP3 player), a camera, a gaming machine, or any other similar functional device. Mobile devices are commonly referred to as user equipment (UE) in UMTS applications, but can also be referred to by those skilled in the art as mobile stations (MS), subscriber stations, mobile units, subscriber units, wireless unit remote units 'mobile devices' , wireless device, wireless communication device, remote device, mobile subscriber station, access terminal (AT), mobile terminal, wireless terminal, remote terminal, handset, terminal, user agent, mobile client, or other A suitable term. For purposes of illustration, it is illustrated that UE 110 is in communication with B, point 108. The downlink (DL), also referred to as the forward-to-key path, represents the communication link from the Node B to the UE, and the uplink (UL), also known as the reverse link, represents the £11 to the B-node. Communication key. As shown, the core network 104 includes a GSM core network. However, as will be appreciated by those skilled in the art, the various concepts provided throughout this disclosure can be implemented in the RAN, or other suitable access network, to provide for other than the GSM network. Type of core network access. In this example, the core network 1-4 uses the Mobile Switching Center (MSC) 112 and the Gateway MSC (GMSC) 114 to support circuit switched services. One or more RNCs, such as RNC 106, may be connected to MSC 112. The MSC 112 is a device that controls dialing setup, dialing routing, and UE mobility functions. The MSC 112 also includes a Visitor Location Register (VLR) (not shown), which includes 201135272 containing information about the user during the UE's coverage within the MSC 112. The GMSC 114 provides a gateway through the MSC 112 for the ue access circuit parent to change network 116. The GMSC II4 includes a Home Location Register (HLR) (not shown), and the HLR contains user data such as information reflecting details of services subscribed to by a particular user. The HLR also contains authentication data that varies from user to user. The Authentication Center (AuC) is associated. Upon receiving a call for a particular ue, the GMSC 114 queries the HLR to determine the location of the ue and forwards the call to the particular MSC serving the location. The core network 104 also serves GPRS. Support Node (SGSN) 118 and Gateway GPRS Support Node (GGSN) 12() to support packet data services. GpRS on behalf of the General Packet Radio Service is designed to be faster than the standard gsm circuit switched data service available. A packet data service is provided. The GGSN 120 provides RAN1〇2 with a connection to the packet-based network 122. The packet-based network 122 can be the Internet, a proprietary data network, or some other suitable packet-based network ^ GGSN The primary strength of 120 is to provide packet-based network connectivity to UE 110. The data packet is transmitted between GGSN 12 and UEU by SGSN 118 in the packet-based domain. The functions performed by the Msc ΐ2 in the circuit switched domain are essentially the same. The UMTS胄 interfacing is a spread-spectrum direct sequence code division multiplex access (DS-CDMA) system. Spread spectrum DS_CDMA multiplies user data by A sequence of pseudo-random bits called chips is extended to a much wider bandwidth. The TD-SCDMA standard is based on such direct sequence spread spectrum techniques and additionally requires time-sharing double guard (TDD) instead of Frequency division duplex (fdd) as used in UMTS/W-CDMA systems of numerous FDD modes 201135272. tdd pairs both uplink (ul) and downlink (DL) between Node B 108 and UE 110 The same carrier frequency is used, but the uplink and downlink transmissions are divided into different time slots of the carrier. Figure 2 illustrates the frame structure of the TD-SCDMA carrier. As illustrated, the TD-SCDMA carrier There is a frame 202 having a length of 1 〇 ms. The frame 202 has two 5 ms subframes 204' and each subframe 2 〇 4 includes seven time slots TS0 to TS6. The first time slot TS0 is often assigned Used for downstream keyway communication' while the first time slot TS1 is often assigned for upstream keyway ventilation. The remaining time slots TS2 to TS6 may be used for the uplink or may be used for the downlink key 'this allows or is greater in the uplink direction or in the downlink direction during periods of higher data transmission. The flexibility of the downlink keyway time slot (DwPTS) 206, the guard period (GP) 208, and the uplink key pilot time slot (UpPTS) 210 (also known as the uplink pilot channel (UpPCH)) are located. Between TS0 and TS1. Each time slot TS0-TS6 allows multiplexing of data transfers over up to 16 code channels. The data transfer on the code channel includes two data portions 212 separated by a mid-sequence signal 214 and is followed by a guard period (GP) 216. The mid-order signal 214 can be used for functions such as channel estimation, while the GP 216 can be used to avoid inter-pulse interference. 3 is a block diagram of communication between Node B 310 and UE 3 50 in RAN 300, where RAN 300 may be RAN 202 in FIG. 2, Node B 31 may be Node B 208 in FIG. 2, and UE 350 may be UE 210 in FIG. In downlink communication, the transmit processor 320 can receive the data from the data source 312 and the control signal from the controller/processor 34A. Transmit processor 320 can provide various signal processing functions for data and control signals as well as reference signals (e.g., pilot frequency signals). For example, the transmit processor 320 can provide cyclic redundancy check (crc) codes for error detection, encoding and interleaving that facilitates forward error correction (FEC), based on various modulation schemes (eg, binary shift phase keying (eg, BPSK), Quadrature Phase Shift Keying (QpsK), Phase Shift Keying (M_PSK), M Quadrature Amplitude Modulation (m_qam), and the like, mapping to signal clusters, using orthogonal variable spreading factor (〇vsf) The expansion is performed [and multiplied by the pilot code to produce the su symbol. The channel estimate from channel processor 344 can be used by controller/processor 34 to determine the encoding, modulation, spreading, and/or scrambling scheme for transmit processor 320. These channel estimates can be derived from reference signals transmitted by UE 350 or from feedback contained in UE 35's intermediate sequence signal 214 (Fig. 2). The symbols generated by the transmit processor 320 are provided to the transmit frame processor to establish a frame structure. The frame processing of the stomach 33 is accomplished by multiplexing the symbol with the mid-order signal 214 (> 2) from the processor 340 processor 340 to create the frame structure' resulting in a series of frames. These frames are then provided to a transmitter 332 which is 4% for various signal conditioning functions, including amplifying, arranging, and (4) the frames onto the carrier for passage via one or more Antenna 334 Performs Downlink Transmission on Wireless Media The one or more smart antennas 334 may be implemented with beam steering to a bidirectional adaptive antenna array or other similar beam technology. At UE 35, receiver 354 receives the downlink transmission via one or more antennas 352 and aligns the transmission to recover the modulated 201135272 signal to the carrier. The information recovered by the receiver 354 is provided to the receive frame processor 360, which parses each frame and provides the midamble signal 214 (Fig. 2) to the channel processor 3 94 and the data The control and reference signals are provided to the receive processor 370. The receiving processor 370 then performs the inverse processing of the processing performed by the transmitting processor 32 in the B node 310. More specifically, the receive processor 370 descrambles and despreads the symbols and then determines the signal cluster points that the B node 31 is most likely to transmit based on the modulation scheme. These soft decisions can be based on channel estimates computed by channel processor 394. The soft decisions are then decoded and deinterleaved to recover the data, control, and reference signals. The CRC code is then checked to determine if the frames have been successfully decoded. The data carried by the successfully decoded frame will then be provided to data slot 372, which represents the application executing in UEho*/ or various user interfaces (e.g., display). The control signal carried by the successfully decoded frame will be provided to the controller/processor 39. When the receiver processor 370 decodes the frame unsuccessfully, the controller/processor 39 can also use the acknowledgement (ACK) and/or negative acknowledgement (NACK) protocols to support the retransmission request for this frame. In the uplink, data from data source 378 and control signals from controller/processor 390 are provided to transmit processor 38A. Data source 378 can represent an application executing in UE 35 and various user interfaces (eg, a keyboard). Similar to the functionality described in connection with the downlink transmission description made by Node B 31, Transmit Processor 38 provides various signal processing functions, including CRC codes, encoding and interleaving to facilitate FEC, mapping to signal clusters, and 0 VSF. The extension, as well as the scrambling, to produce a series of 11 201135272 column symbols. The channel signal transmitted by the channel processor 394 & Node B 31 or the channel estimate derived from the feedback contained in the mid-order signal transmitted by the Node B 310 can be used to select the appropriate coding, modulation, spreading and / or scrambling scheme. The symbols generated by the transmit processor 380 will be provided to the transmit frame processor 382 to establish a frame structure. The frame processor 382 creates the frame structure by multiplexing the symbols with the midamble signal 214 (Fig. 2) from the controller/processor 39, resulting in a series of frames. These frames are then provided to a transmitter 356 that provides various signal conditioning functions including amplifying, filtering, and modulating the frames onto a carrier for wireless via one or more antennas 352. Uplink transmission on the media. The uplink dance is handled at Node B 310 in a manner similar to that described in connection with the receiver function at the UE 35〇. Receiver 335 receives the uplink transmission via one or more antennas 334 and processes the transmission to recover the information modulated onto the carrier. The information recovered by the receiver 335 is provided to the receive frame processor 336, which parses each frame 'and provides the intermediate sequence signal 214 (FIG. 2) to the channel processor 344 and the data, Control and reference signals are provided to receive processor 338. The receiving processor 337 performs inverse processing of the processing performed by the transmitting processor 380 in the UE 350. The data and control signals carried by the successfully decoded frame can then be provided to the data slot 339 and/or the controller/processor, respectively. If the receiving processor decodes some of the frames unsuccessfully, the controller/processor 340 may also use the ACK and/or NACK protocol to support retransmission requests for such frames. 12 201135272 Controllers/processors 340 and 390 can be used to direct operations at Node B 31 and UE 350, respectively. For example, the controller/processors 34A and 39〇 provide various functions including timing, peripheral interfaces, voltage regulation power management, and other control functions. The computer readable media of the memories 342 and 392 can store data and software for the Node B 310 and the UE 350, respectively. The scheduler/processor 346 at Node B 310 can be used to allocate resources to the ue and schedule downlink and/or uplink transmissions for the UE. 4 is a block diagram illustrating a configuration of a device 4 that may be a UE 11A. Apparatus 400 can include a wireless interface 〇2, a processing system 〇4, and a machine readable medium 406. The wireless interface 402 can be integrated into the processing system 4〇4 or distributed across multiple entities in the device.

Software code may be stored in a memory unit and executed by a processor The memory unit can be implemented within the processor or external to the processor, in the latter case it can be communicatively coupled to the processor TD-SCDMA standard via various means known in the art. Three schemes are provided to determine the location of the UE without using Gps: 1. Cell service area ID: Use the current cell service area to approximate the location of ue 2. Obtained observation time by UE-assisted. Poor (〇TD〇A ): ue measures the arrival time difference of several cell service areas and signals the measurement results to the network, where the network performs position calculation. OTDOA uses SFN-SFN between the neighbor cell service area and the reference cell service area. (System frame number to system frame number) Observe the time difference. 3. UE-based OTDOA: The UE measures the arrival time difference of several cell service areas and also performs location calculation. Finally, the UE signals the positioning result to the network. Based on the UE's OTDOA, the TD-SCDMA standard specifies that the Node B (NB) broadcasts the location information of the serving cell service area and the neighbor cell service area in the system information message. Specifically, the system information block type is 15.5 (SIB-15.5). Includes UE-based OTDOA assistance data for UE-Based information element (IE). This IE indicates the location of the serving cell service area and the neighbor cell service area. Specifically, it includes the latitude and longitude information of the reference cell service area. Provides neighbor cell service in the UE positioning OTDOA neighbor cell info for UE-based IE The relative position of the zone relative to the reference cell service zone. However, in addition to the reference base station, UE-based positioning may require at least three base station measurements. Specifically, each of the three base stations is required with reference. The observation time difference between the base stations. Since the UE may not be able to receive valid signals from a sufficient number of base stations in the TD-SCDMA network, in one aspect of the present case, the multimode TD-SCDMA UE can utilize the CDMA lx network to improve signal detection and execution. Other measurements for UE location calculus. When there is not enough 15 201135272 base station with good signal quality in the TD-SCDMA network, the UE time position can be estimated using the observation time difference between the base station in the CDMA lx BS and the base station in the TD-SCDMA network. The system requirements in the 3GPP and 3GPP2 standards are that TD-SCDMA and CDMA lx systems are synchronized. Specifically, TD-SCDMA with a length of 10 ms is aligned with a 20 ms long CDMA frame. These frames are also aligned with the GPS time. In a CDMA lx system, the location of a serving base station (BS) is indicated in a system parameter message (SPM). In one aspect of the present case, for multimode terminals, UE location estimation is supported by means of searching and measuring CDMA lx networks as a complement to the TD-SCDMA network. Therefore, multimode (TD-SCDMA and CDMA lx) terminals can not only search for TD-SCDMA base station signals, but also search for CDMA lx base station signals to improve the availability and accuracy of the UE positioning procedure. Referring to Figure 6 and with further reference to Figure 7, a UE location determination procedure 600 will be described, where in step 602, a cell service area (base station), such as a cell service area, called a neighbor cell service area within the range of the UE 702 is selected. 710, 712, 720, and 722 are included for inclusion in the candidate base station group. In one aspect of the present case, the signal interference plus noise ratio is selected as a metric for selecting a preferred candidate base station such that: • the signal-to-interference ratio (SIR) of the primary shared control entity channel (P-CCPCH) can be measured by: The candidate TD-SCDMA NB is determined, which is represented by S_td(i) in dB. Assume that index i references each available TD-SCDMA NB with available signal measurements. 16 201135272 • A candidate CDMA lx base station can be determined by measuring the pilot frequency interference noise ratio (SINR) of a CDMA lx base station, which is represented by S_cd(j) in dB. Assume that index j references each available CDMA BS with available signal measurements. Therefore, the multimode terminal can select the best one of the TD-SCDMA and CDMA lx networks for the UE based positioning decision procedure, wherein. In order to adjust for different network technologies, the following adjustments are used when selecting a base station: • TD-SCDMANB: S_td(i)-Offset_td • CDMA lx BS: S_cd(j)-Offset_cd The above offset or adjustment value is Offset_td, Offset_cd (in dB) is constant for a particular Radio Access Technology (RAT). In step 604, in one aspect of the present case, the strongest TD-SCDMA B node from the candidate cell service region in the above signal measurement protocol will be selected as the reference cell service region, which is identified as TD Reference cell service area 71 0. In step 606, the UE measures from each neighbor cell service area (TD-SCDMA or CDMA, such as TD neighbor cell service area 712, CDMA lx neighbor cell service area B 720, and CDMA lx neighbor cell service area C 722) Time difference to the reference cell service area (TD reference cell service area 7 1 0). The observation time difference in the TD-SCDMA network is defined as the system frame number (SFN-SFN) observation time difference. That is, the UE 702 is capable of measuring the delay of the received frame boundary of the neighbor cell service area relative to the reference cell service area. The SFN-SFN observation time difference is defined as the difference in arrival time of the frame boundary of the TD-SCDMA/CDMA lx neighbor cell service area relative to the frame boundary of the reference cell service area. If it is detected that the frame boundary of the neighbor cell service area is received after the frame boundary of the reference cell service area, the SFN-SFN observation time difference is positive. The observed time difference of CDMA lx relative to the TD-SCDMA reference cell service area 710 can be similarly measured, except that there are two TD-SCDMA frames per CDMA frame and thus the closest TD-SCDMA frame boundary is used. . Figure 5 includes a frame timing diagram 500 illustrating the concept of determining the difference between a CDMA lx frame boundary and a TD-SCDMA frame boundary. In the above procedure, at least three neighboring base stations (TD-S*CDMANB or CDMABS) such as TD neighbor cell service area A712, CDMA lx cell service area B 720, and CDMA lx neighbor cell service area C 722 are executed. Time difference measurement relative to TD-SCDMA reference cell service area 710. In step 608, the UE 702 retrieves the location of the TD-SCDMA reference cell service area 710 from SIB-15.5 and the location of the neighbor cell service area, such as the TD neighbor cell service area A 712 in the TD-SCDMA network. . For a CDMA lx neighbor cell service area such as CDMA lx neighbor cell service area B 720 and CDMA lx neighbor cell service area C 722, UE 702 needs to retrieve each neighbor point in these neighbor cell service areas. SPM of the cell service area. In step 610, the UE 702 uses the observed time difference and location of the base stations to estimate the UE location. Figure 8 is a functional block diagram of an exemplary block of the 2011 2011 circuit, which is executed in accordance with an aspect of the present invention. Block 8〇2 includes selecting a subset of candidate cell service regions from a plurality of neighbor cell service regions based on criteria. Additionally, block 804 includes identifying a reference cell service area. In addition, block 806 includes determining characteristics associated with propagation times associated with both the reference cell service region and the subset of candidate cell service regions. Moreover, block 8〇8 also includes setting the position based on the determined characteristics. In an arrangement, means 350 for wireless communication includes means for selecting a subset of candidate cell service regions from a plurality of neighbor cell service regions based on criteria; means for identifying a reference cell service region; for determining A component associated with a characteristic associated with a propagation time of both a reference cell service region and a subset of candidate cell service regions; and means for a put position based on the determined characteristic. In one aspect, the aforementioned means may be a processor configured to perform the functions recited by the means described. In another aspect, the aforementioned means may be a module or any device configured to perform the functions recited by the aforementioned means.
