200529590 九、發明說明: 【發明所屬之技術領域】 本發明係有關一種將資料從一移動站傳輸到一基地站 的方法,一基地站特別別是一基地站系統以及一移動站特 別是一行動電話。 【先前技術】 經常提出的是有關行動無線電系統的特別是使用俗稱 之封包接達方法或是封包導向型資料連接,由於經常出現 的訊息型式具有一非常高的猝發係數,因此只存在有爲很 長之待機暫停時段所中斷的很短活動時段。此例中,較之 其中存在有連續資料束的其他資料傳輸方法,封包導向型 資料連接可明顯地提高其效率;由於在具有連續資料_束 丨 -— 的資料傳輸方法中一旦配置了例如載體頻率或是時間間隙 之類的資源,則該資源會在整個通信連結期間保持其配置 ,亦即該資源即使在未進行資料傳輸時也,會保持其配置, 使得其他用戶無法取得這個資源。這會引致無法行動無線 電系統之窄頻波譜作最佳化的應用。 未來的行動無線電系統例如那些順應UMTS (通用行動 無線電通信系統)型行動無線電規範的系統將可提供多種 不同的服務,其中除了純粹的語音傳輸之外多媒體應用將 變得日益重要。具有不同傳輸速率之服務的附屬多樣性會 在未來行動無線電系統之空氣介面上需要非常有彈性的接 達協定。已證明封包導向型資料傳輸方法非常適合這裡的 應用。 200529590 有關UMTS型行動無線電系統已提出俗稱aRQ(自動重 複請求)的方法以便用於封包導向型資料連接。這種方法涉 及了對由發報機送到接收器之資料封包在一旦解碼後進行 之接收器一側的品質檢驗。假如所接收到的資料封包有錯 誤,則接收器會請求由發報機重新傳輸這個資料封包,亦 即,由發報機將一重新傳輸的資料封包送到接收器上。這 個請求也經常被稱爲回覆確認(ACK)或不回覆確認(NACK) 〇 對未來UMTS型「強化專用通路(E-DCH)」式上行通路 的標準化而言,考量的是使用一種經常也結合了軟性組合 作用(在解碼之前一封包的各種傳輸的覆蓋)的快速混合式 ARQ(HARQ)方法,類似於已對高效能下行封包存取技術 (HSDPA)[TR]進行的標準化。與HSDPA相反地,可管制 UMTS型上行的功率使得系統中的整體干涉現象受到控制 。此例中,係藉一參考通路(DPCCH亦即專用實體控制通 路)由俗稱的功率補償作用(也稱作Θ係數)定義出每一個通 路的傳送功率。這些功率補償作用係透過發信號知會終端 或是透過已定義的方法由參考資料[TS25.2 14]計算出的, 並用以確保每一個通路平均都能達到其標的的錯誤速率。 每個資料通路都會用到一補償作用(功率補償作用)。 功率管制意指接收功率與必要數値的偏差將會非常小 的規則。特別是假如接收功率只比必要數値小了一點,結 果是很可能無法在使一封包的第一次傳輸解碼沒有錯誤。 假如現在以精確相同的功率補償送出一第一重新傳輸,其 -6- 200529590 規則是在兩個封包覆蓋之後用於供錯解碼所需要的總能量 會大大超出。例如[R 1 - 0 3 8 04 1 ]中的模擬顯示了功率管制上 行中的規則是一封包最晚會在第二次傳輸獲致理解,無論 其第一次傳輸的平均區塊錯誤速率究道是17%或49%。這 個實例顯示了其規則爲第二傳輸係在太高的功率下施行的 。這意指一方面於系統內產生了不必要的大量額干涉另一 方面發報機使用了不必要之傳送功率的高準位,這縮短了 可再充電電池的待機時間且在某些狀況下甚至可引致經由 功率限制之產量的滑落。該功率限制意指該移動站至少在 很短的時段內無法以所提供的固有功率送出所有服務(各 資料通路亦即各通路)且因此必須減低其功率,通常這類例 子裡會以相同的倍率減小所有資料通路的功率,以致其整 體功率不會超出其最大的可能功率。 鑒於經常可獲致符合該功率的密碼分割多功法(C D Μ 亦即以不同的密碼送出E-DCH及相關的5個通路),必須 經由不同的路徑管制用於時間分割多功法(T D Μ亦即以相 同的密碼送出E-DCH及相關的5個通路)的接收能量或接 收功率。由於這裡係隔行顯示具有和Q 〇 S有關之不同要求 或是不同的傳輸模式(例如具有/不具有HARQ)的不同通路 並當作所謂的已編碼複合式輸送通路(CCTrCH)送出,其功 率搭配會在上行的傳送功率內造成快速變化,故在技術上 很難施行且具有效率上的缺點(峰値對平均値的功率比)。 習知設計中亦即對先前所定義之各資料通路或是輸送通路 (輸送通路指的是正常情況下用於U Μ T S內同時這裡也用作 200529590 資料通路的名稱)的組合而言,係使各種通路的接收品質符 合俗稱的速率匹配(RM)屬性亦即指派給每一個輸送通路的 屬性。該RM屬性會定出不同的輸送通路於已編碼複合式 輸送通路(CCTrCH)內所佔已編碼位元數目的比例。藉由高 數値的RM屬性使該附屬通路獲致優先權並於CCTrCH內 取得非常高量額的空間。這意指能以較低的編碼速率傳送 這個通路,這本身會造成更高的Eb/N〇値亦即使這個通路 具有較高的能量。如是此例中,並非經由功率而是經由該 傳輸通路中可用的時間管制其能量含量。 假如每個傳輸時間間隔(TTI亦即一傳輸單元在實體層 上的期間且因此指的是隔行傳送資料所跨越的時間間隔) 內都能傳送出數目不同於先前之區域(資料封包)傳輸數目 的輸送區塊,則藉由對重新傳輸封包施行純粹的功率搭配 使CDM過於匹配一封包的總能量的作業可能變得很困難 。現在假如跨越整個TTI長度進行隔行傳送(目標)如同TDM 的情形,這會產生跨越時間作快速改變的傳送功率而具有 上述問題。 這個問題只出現在將受各較低層控制的快速HARQ法 用於封包導向型資料通路時。這並非習知之上行的情形。 對下行作業中的HARQ法而言,這個問題也不致達到這個 程度,這是由於這裡並未設想快速的功率管制且接收功率 與必要數値的偏差可以大得多的緣故。因此下行作業中不 致出現或是少出現所謂近遠效應的問題亦即來自一移動站 之信號的覆蓋性太強因此使基地站更難接收來自另一移動 200529590 站的微弱信號。文獻[JK SO 3]中已討 hsdpa進行功率匹配的想法。於 E-DCH上的應用以及上述所有發信 ,然而文獻中尙未處理這個領域。 此外,H S D P A只使用了 一種每 個輸送區塊的輸送協定,因此不致i 區域之時間分割多功法(TDM)的問 包施行純粹的輸送功率匹配作業。 【發明內容】 因此本發明的目的是明確提出 傳輸到基地站的方法,以便在來自 允許吾人在接收一側進行可靠的資 這個目的係藉由如本發明申請 特性達成的。各例中係由本發明申 定義出本發明的較佳及有利實施例 有裝置申請範圍之延伸,其相關於 〇 本發明並未排除將資料從基地 進一步資料從該移動站傳輸到基地 本發明產生了一種平均而言已 引致更低的功率消耗且因此引致更 減少了行動傳輸裝置因爲功率限制 下操作的時間。在單元位準上透過 生的干涉更少,這轉而引致了更高 論了使重新傳輸封包與 、是第一'次出現對有關 號的特定實施例的需求 個TTI都精確地含有一 ϋ現來自不同輸送通路/ 題且能夠爲重新傳輸封 一種將資料從一移動站 其他信號的微小干涉下 料解碼。 專利範圍各獨立項目之 請專利範圍之各附屬項 。在本發明的架構中亦 方法申請範圍的獨立項 站傳輸到移動站或是將 站的方法。 減低的傳送功率。這會 長的電池壽命或是引致 只能在低於最佳化條件 已減少的傳送功率所產 的單元容量。已減小的 200529590 傳送功率也會在各鄰近單元上產生更少的干擾,因此這個 方法也可依這種方式引致更高的單元容量。 以用於TDM之速率匹配(RM)屬性或是用於CDM之功 率補償作用爲主的一般化槪念’可以非常容易地合倂到現 有的UMTS-FDD規範內且包含於TDM或CDM內傳送各種 輸送通路的解決方法。以更一般化的詞句說明,較之第一 資料封包的能量可透過速率匹配(RM)屬性、功率補償作用 或者除了 TDM或C DM之外的其他方法可透過能應用在相 關方法上的能量補償作用使各重新傳輸之資料封包的能量 更爲匹配。取決於所應用的方法,可將第一能量補償作用 或是第一功率補償作用與重新傳輸之能量補償作用或是重 新傳輸之功率補償作用區分開。其中前者係和各輸送區塊 的初始傳輸有關而後者則與其重新傳輸有關。 【實施方式】· 第1圖顯示的是一種基地站1與移動站2之間的標準 通信作業,例如UMTS型行動無線電系統。其中係透過俗 稱的「下行」通路D L將資訊從基地站1傳送到移動站2 上,同時係透過俗稱的「上行」通路UL將資訊從移動站2 傳送到基地站1上。爲了控制用於資料傳輸的方法,可設 置據此作程式規劃的處理器裝置P E。 不僅用於資料通路的功率補償作用是發報機(移動站) 上己知的,同時可藉由快速HARQ法得到具有數目等於封 包之可能傳輸之最大數目之尺度nmax的功率補償向量。對 封包之不同傳輸(第一資料封包或是重新傳輸資料封包或 -10- 200529590 是用於1,2及其他重新傳輸)而言’可將該向量中的其他元 素用作此例中的功率補償作用。 首先將要討論可藉由與重新傳輸資料封包的功率匹配 以提供所需要之接收能量的方法。 規則是功率補償向量會取決於接收功率與必要數値的 偏差或是所用的區塊錯誤率及HARQ法(例如追蹤組合或是 增量備用)。 假如完全未接收到一傳輸(第一資料封包)’發報機可 在必要時例如透過不存在來自接收器(基地站)的回覆確認 (例如不存在ACK或NACK信號)偵測到這個訊息。此例中 ,可於後續的傳輸(重新傳輸資料封包)中再次使用用在已 失去傳輸的功率補償。亦即功率補償向量的指數只有在發 報機能假定接收器已接收到資料(且有封包的軟性數値出 現於記憶體內)時且只有在解碼失敗時增量。 現在存在有使網路透過於較高層內發信號爲終端機提 供這個完整功率補償向量的可能性,亦即基本上將先前只 含一個數値的傳輸取代爲向量的傳輸。其優點是網路能爲 每一個終端機定出這類補償並使之最佳化。例如這裡可以 使用對接收功率與必要數値之偏差分布的評估。特別是這 類偏差係取決於該終端機的速率以及各通路性質。 根據所用的HARQ法其接收功率與必要數値之偏差的 分布以及區塊錯誤速率的熟悉度會在覆蓋之後出現彎曲, 使吾人能夠定出到底需要多少額外的接收能量以便平均而 g能在第η次傳輸一封包之後於p個百分比的例子裡進行 -11- 200529590 解碼。也可針對預先指定的必要數値η和p定出一功率補 償向量。 如同先前的情形,進一步的可能性是只定出第一傳輸 的功率補償以判定用於與此無關例如頻率變化更大之各重 新傳輸的功率補償。同時可使用預先定義(例如用於各標準 通路性質及/或訂戶速率之類的表格)同時也是終端機上己 知的表格,以致只須傳送一個可提供表格上將要用在那個 點上之資訊的指數。表格的使用可減少所需要的發信號作 業。除了之外減少了網路中處理的一般管理,這是由於只 要對終端機作粗略分類(例如根據其通路或速率)就足夠的 緣故。 甚至更簡單的變型是僅連續地使用一個功率補償向量 且因此不須要發信號。同時也可以只使用其功率補償可明 確指出一重新傳輸之功率補償與第一傳輸(第一資料封包) 之功率補償間差異的向量。 在未發信號下,有一種方法的運作方式是發報機會獨 立地爲其功率補償向量施行最佳化。不過,該發報機並不 知道每一個封包的接收功率而另外爲這個參數發信號則顯 得過於事倍功半。替代地,例如可藉由發報機使用每個封 包所需要之傳輸的統計評估値當作控制數値。例如假若有 多於tu個百分比需要第η次傳輸則其附屬的功率補償(亦即 第η - 1次傳輸)會增加d u分貝,假若有少於t i個百分比需 要第η次傳輸則其附屬的功率補償會減小d i分貝。 一種實施例變型定下的規定是定義各重新傳輸封包不 -12- 200529590 會以高於第一傳輸之功率送出。依這種方式吾人可確保該 網路能估s十至少可預期最大的接收功率。不過,由於該網 路並不知道每一個該傳送功率的新近(較小)數値,故沒有 機會以這種使用已主動減小干涉的變型將資源指派給其他 訂戶及/或服務。理論上’這對知道該功率補償向量的網路 而言是可行的。 不過,也可能出現完全未接收到該第一傳輸的情形, 例如,用以辨識第一封包之情形的控制資訊被編碼或是沒 有收到識別資訊。 此例中,接收器無法於第二次傳輸中從第一次傳輸獲 利。此例中,施行另一補償對第二次傳輸而言沒有任何意 義’而是适裡第一次傳輸「確貫」就是第一次傳輸且因此 應該以用於第一次傳輸的功率補償送出。 發報機可在必要時偵測究竟是完全失去該第一次傳輸 或者只是未能解碼。例如發報機可在兩個情況中偵測出是 否接收到來自接收器的不同回覆確認。例如接收器可回覆 確認已正確地接收到各封包(以回覆確認訊息 ACK)並再次 請求未正確解碼的各封包(以不回覆確認訊息N A C K)。假如 完全失去該封包則接收器無法送出任何這類信號。這種情 形特別是發生在接收器完全未偵測到已送出該封包的訊息 時。不過當作另一解釋用實施例,則該接收器也會在證實 雖則已送出該封包然而由於未正確地接收到附屬的控制資 訊故無法解讀該資料時不送出任何訊息(A C K、N A C K兩者 都不)。替代地,也可引進精確的發信號作業而明白地知會 -13- 200529590 已發生這種狀況(例如以Τ Ο N A K亦即「完全不回覆確認」 訊息)。 取決於是否完全失去該第一封包,應該將用於第一或 第二次傳輸的功率補償用在下一次傳輸。同樣地,對傳輸 數目η而言假如先前完全失去m個封包則可以使用用於傳 輸數目n-m的功率補償。 先前已依基本上以使用功率補償爲主或是以使用不同 數値之速率匹配屬性爲主的具體實例說明了本發明。吾人 應該指出的是更一般性地說,無論用於設定該能量的具體 方法爲何,儘管此具體方法通常用於能量設定,用於資料 封包的不同傳輸上的方法都會落在本發明的架構內。 本發明之變型提供了 -這種能量匹配的型式及強度也能夠取決於除了先前送出 之傳輸數目以外的係數; -可將現有的速率匹配(RM)屬性擴充爲一向量並據此發 信號; -已明確指定的運算法則說明了一種可在最佳可能之功率 補償的一般條件下對各通路資源作最佳應用(亦即在不 影響功率管制下傳送功率)的CCTrCH型輸送格式匹配作 業。 -現有的速率匹配(RM)屬性並非應用在輸送通路的基礎 (半靜態的TF參數)上而是單獨地用於每一個輸送區塊 (動態的TF參數)上。 進行能量匹配的更一般化策略使該方法在使用上有更 -14- 200529590 多用途’特別是適合用於幣碼分割多功法(C D Μ亦即以不同 的密碼送出Ε -

Description of the invention: [Technical field to which the invention belongs] The present invention relates to a method for transmitting data from a mobile station to a base station, a base station, especially a base station system, and a mobile station, especially an action phone. [Prior art] Often related to mobile radio systems, especially using the commonly known packet access method or packet-oriented data connection, because the frequently occurring message type has a very high burst coefficient, so there are only promising A short period of activity interrupted by a long standby pause period. In this example, compared with other data transmission methods in which there are continuous data bundles, the packet-oriented data connection can significantly improve its efficiency; once a carrier such as a carrier is configured in a data transmission method with a continuous data bundle Resources such as frequency or time slot, the resource will maintain its configuration throughout the communication link, that is, the resource will maintain its configuration even when no data is being transmitted, making other users unable to obtain this resource. This can lead to the optimization of the narrow-frequency spectrum of inoperable radio systems. Future mobile radio systems, such as those compliant with the UMTS (Universal Mobile Radio Telecommunications System) mobile radio specifications, will provide a variety of different services, of which multimedia applications will become increasingly important in addition to pure voice transmission. The ancillary diversity of services with different transmission rates will require very flexible access agreements on the air interface of future mobile radio systems. Packet-oriented data transmission methods have proven to be very suitable for this application. 200529590 A method commonly known as aRQ (Automatic Repeat Request) has been proposed for UMTS-type mobile radio systems for use in packet-oriented data connections. This method involves a quality check on the receiver side of the data packet sent from the transmitter to the receiver once decoded. If there is an error in the received data packet, the receiver will request the transmitter to retransmit the data packet, that is, the transmitter will send a retransmitted data packet to the receiver. This request is often referred to as acknowledgement of acknowledgement (ACK) or non-acknowledgement of acknowledgement (NACK). For the standardization of future UMTS-type "Enhanced Dedicated Channel (E-DCH)" uplink channels, the consideration is to use a combination of A fast hybrid ARQ (HARQ) method that provides a soft combination effect (coverage of various transmissions of a packet before decoding) is similar to the standardization of high-performance downlink packet access technology (HSDPA) [TR]. In contrast to HSDPA, the controllable UMTS uplink power allows the overall interference phenomenon in the system to be controlled. In this example, a reference channel (DPCCH, also known as a dedicated entity control channel) is used to define the transmission power of each channel by the commonly-known power compensation function (also known as the Θ coefficient). These power compensation effects are calculated by notifying the terminal by signaling or by a defined method from the reference material [TS25.2 14], and are used to ensure that each path can reach its target error rate on average. A compensation effect (power compensation effect) is used for each data path. Power regulation means a rule that the deviation of the received power from the necessary number will be very small. In particular, if the received power is only a little less than necessary, the result is that it is likely that the first transmission of a packet cannot be decoded without errors. If a first retransmission is now sent with exactly the same power compensation, its -6-200529590 rule is that the total energy required for error decoding after two packets are covered will be greatly exceeded. For example, the simulation in [R 1-0 3 8 04 1] shows that the rule in power regulation uplink is that a packet will be understood at the second transmission at the latest, regardless of the average block error rate of the first transmission. 17% or 49%. This example shows that the rules are enforced by the second transmission system at too high power. This means that, on the one hand, an unnecessary large amount of interference is generated in the system; on the other hand, the transmitter uses an unnecessary high level of transmission power, which shortens the standby time of the rechargeable battery and in some cases even This can lead to slippage of output through power limitation. The power limitation means that the mobile station cannot send out all services (each data path, that is, each path) with the inherent power provided for at least a short period of time and therefore must reduce its power. Usually in such examples, the same The magnification reduces the power of all data paths so that its overall power does not exceed its maximum possible power. In view of the fact that a cryptographic division multiple function method (CD Μ, that is, sending E-DCH and related 5 channels with different ciphers) can often be obtained, it must be controlled by different paths for time division multiple function method (TD Μ That is, the received energy or received power of the E-DCH and related 5 channels is sent with the same password. Since the interlaced display here has different requirements related to QOS or different transmission modes (such as with / without HARQ) and is sent as a so-called coded composite transmission channel (CCTrCH), its power is matched It will cause rapid changes in the uplink transmission power, so it is technically difficult to implement and has a shortcoming in efficiency (power ratio of peak chirp to average chirp). In the conventional design, that is, the combination of the previously defined data paths or transmission paths (the transmission path refers to the name that is normally used in the U M TS and also used as the 200529590 data path here). Make the receiving quality of various channels conform to the commonly known rate matching (RM) attribute, that is, the attribute assigned to each transmission channel. The RM attribute determines the ratio of the number of coded bits in the coded composite transport path (CCTrCH) for different transport paths. With the high number of RM attributes, this ancillary channel gets priority and obtains a very high amount of space in CCTrCH. This means that this path can be transmitted at a lower coding rate, which in itself will result in a higher Eb / N0 値 even if this path has higher energy. In this case, the energy content is regulated not by power but by the time available in the transmission path. If each transmission time interval (TTI is the period of a transmission unit at the physical layer and therefore refers to the time interval spanned by interlaced data), the number of transmissions can be different from the previous number of regional (data packet) transmissions. In the transmission block, the operation of making the CDM too much match the total energy of a packet may be difficult by performing pure power matching on retransmitted packets. Now, if interlaced transmission (target) is performed across the entire TTI length as in the case of TDM, this will cause the transmission power to change rapidly over time and have the above problems. This problem only arises when fast HARQ methods controlled by lower layers are used for packet-oriented data paths. This is not the case for the habitual ascent. For the HARQ method in downlink operation, this problem does not reach this level, because fast power regulation is not envisaged here, and the deviation of the received power from the necessary number can be much larger. Therefore, the problem of the so-called near-far effect does not occur in the downlink operation, that is, the coverage of the signal from one mobile station is too strong, which makes it more difficult for the base station to receive weak signals from another mobile 200529590 station. [JK SO 3] has discussed the idea of hsdpa for power matching. The application on E-DCH and all the above-mentioned transmissions, however, this field is not dealt with in the literature. In addition, H S D P A uses only one transmission protocol for each transmission block, so it does not cause the time-division multiple power method (TDM) of the i zone to perform pure transmission power matching. [Summary of the Invention] The object of the present invention is therefore to explicitly propose a method for transmitting to a base station in order to allow us to make reliable data on the receiving side. This object is achieved by the characteristics of the application of the present invention. In each case, the preferred and advantageous embodiments of the present invention are defined by the present application and have an extension of the scope of application of the device, which is related to the present invention does not exclude the transmission of data from the base further data from the mobile station to the base. This results in an average that has resulted in lower power consumption and therefore more reduced time for mobile transmission devices to operate due to power constraints. There is less interference at the cell level, which in turn leads to a higher argument that the need to retransmit a packet and the first occurrence of a particular embodiment of the relevant number. The TTI contains exactly one frame. It now comes from a different transmission path / problem and can be used for retransmission to seal and decode data with small interference from other signals of a mobile station. Individual items in the scope of the patent In the framework of the present invention, there is also a method for transmitting stand-alone items within the scope of the application to a mobile station or a method for transmitting the station. Reduced transmission power. This results in long battery life or results in cell capacity that can only be produced below the reduced transmission power of the optimized conditions. The reduced 200529590 transmission power also produces less interference on neighboring units, so this method can also lead to higher unit capacity in this way. The generalized idea that the rate matching (RM) attribute used for TDM or the power compensation function used for CDM can be easily integrated into the existing UMTS-FDD specification and included in TDM or CDM for transmission Solutions for various transport paths. In more general terms, the energy of the first data packet can be compared with the rate matching (RM) attribute, power compensation effect, or other methods other than TDM or CDM. The energy compensation can be applied to related methods. The effect makes the energy of each retransmitted data packet more matched. Depending on the method used, the first energy compensation effect or the first power compensation effect may be distinguished from the retransmission energy compensation effect or the retransmission power compensation effect. The former is related to the initial transmission of each transmission block, while the latter is related to its retransmission. [Embodiment] · Figure 1 shows a standard communication operation between base station 1 and mobile station 2, such as a UMTS mobile radio system. Among them, information is transmitted from base station 1 to mobile station 2 through the so-called "downlink" path D L, and information is transmitted from mobile station 2 to base station 1 through the commonly known "uplink" path UL. In order to control the method for data transmission, a processor device PE which is programmed accordingly can be set. Not only is the power compensation function used for the data path known on the transmitter (mobile station), but the power compensation vector with a number nmax equal to the maximum number of possible transmissions of the packet can be obtained by the fast HARQ method. For different transmission of packets (the first data packet or retransmitted data packet or -10- 200529590 is used for 1, 2 and other retransmissions) 'the other elements in this vector can be used as power in this example Compensation effect. First, we will discuss ways to provide the required received energy by matching the power of retransmitted data packets. The rule is that the power compensation vector will depend on the deviation of the received power from the necessary number or the block error rate used and the HARQ method (such as tracking combination or incremental backup). If a transmission (first data packet) is not received at all, the transmitter can detect this message if necessary, for example, by the absence of a reply from the receiver (base station) (for example, the absence of an ACK or NACK signal). In this example, the power compensation for lost transmission can be reused in subsequent transmissions (retransmission of data packets). That is, the index of the power compensation vector can only be incremented when the transmitter can assume that the receiver has received the data (and the soft number of the packet appears in the memory) and only when the decoding fails. There is now the possibility of making the network provide the terminal with this complete power compensation vector by sending a signal in a higher layer, that is, basically replacing the transmission that previously contained only a single number with a vector transmission. The advantage is that the network can determine and optimize this type of compensation for each terminal. For example, an evaluation of the deviation distribution of the received power from the necessary number can be used here. In particular, this type of deviation depends on the speed of the terminal and the nature of each channel. According to the HARQ method used, the distribution of the deviation of the received power from the necessary number and the familiarity of the block error rate will bend after coverage, so that we can determine how much additional received energy is needed to average and g can After transmitting a packet n times, it decodes in the p-percentage example-11-200529590. A power compensation vector can also be determined for the pre-specified necessary numbers 値 η and p. As in the previous case, a further possibility is to determine only the power compensation for the first transmission to determine the power compensation for the retransmissions which are not related to this, e.g. the frequency changes more. At the same time, pre-defined forms (such as those used for the properties of standard channels and / or subscriber rates) can also be used, which are also known on the terminal, so that only one of the information provided on the form will be used at that point. Index. The use of forms can reduce the number of signaling tasks required. In addition to this, the general management of processing in the network is reduced, since only a rough classification of the terminals (for example, based on their path or speed) is sufficient. An even simpler variant is to use only one power compensation vector continuously and therefore no signalling is required. At the same time, only the vector whose power compensation can clearly indicate the difference between the power compensation of a retransmission and the power compensation of the first transmission (first data packet) can be used. One way to do this without signaling is to have the transmitter independently optimize its power compensation vector. However, the transmitter does not know the received power of each packet and it is too much work to signal this parameter. Alternatively, for example, a statistical evaluation of the transmission required for each packet by the transmitter may be used as the control number. For example, if there are more than tu percentages that require the nth transmission, its auxiliary power compensation (that is, the nth-1st transmission) will increase du decibels. If there are less than ti percentages that require the nth transmission, its auxiliary Power compensation will reduce di decibels. One embodiment variant sets the rules to define that each retransmission packet will not be sent out at a higher power than the first transmission. In this way we can ensure that the network can estimate at least the maximum receive power that can be expected. However, because the network does not know each of the recent (smaller) numbers of the transmitted power, there is no opportunity to assign resources to other subscribers and / or services in this variation using active reduction interference. This is theoretically feasible for networks that know the power compensation vector. However, the first transmission may not be received at all, for example, the control information used to identify the first packet is encoded or the identification information is not received. In this example, the receiver cannot profit from the first transmission in the second transmission. In this example, the implementation of another compensation does not make any sense to the second transmission, but rather the first transmission is "consistent", which is the first transmission and therefore should be sent with the power compensation used for the first transmission. . The transmitter can detect, if necessary, whether it has completely lost the first transmission or just failed to decode. For example, the transmitter can detect in two cases whether it has received different acknowledgements from the receiver. For example, the receiver may reply to confirm that each packet has been received correctly (to reply to the acknowledgement message ACK) and request the packets that are not decoded correctly (to not reply to the acknowledgement message N A C K). The receiver cannot send out any of these signals if the packet is completely lost. This situation occurs especially when the receiver does not detect a message that the packet has been sent at all. However, as another embodiment for interpretation, the receiver will not send any message (both ACK and NACK) when it is confirmed that although the packet has been sent, but the auxiliary control information has not been correctly received and the data cannot be interpreted Neither). Alternatively, an accurate signalling operation may be introduced to clearly inform that this situation has occurred (for example, with a TO NAK, which is a "no reply at all" message). Depending on whether the first packet is completely lost or not, the power compensation for the first or second transmission should be used for the next transmission. Similarly, for the number of transmissions η, if m packets have been completely lost previously, power compensation for the number of transmissions n-m can be used. The present invention has been described previously with specific examples that basically use power compensation primarily or rate matching properties using different numbers. I should point out that in more general terms, regardless of the specific method used to set the energy, although this specific method is usually used for energy setting, the methods used for different transmissions of data packets will fall within the framework of the present invention . Variations of the present invention provide that the type and intensity of this energy matching can also depend on coefficients other than the number of transmissions previously sent out; the existing rate matching (RM) attributes can be expanded to a vector and signaled accordingly; -The algorithm has been clearly specified to explain a CCTrCH type transmission format matching operation that can make the best use of the resources of each channel under the general conditions of the best possible power compensation (that is, transmit power without affecting power control). -Existing rate matching (RM) attributes are not applied on the basis of the transport path (semi-static TF parameters) but individually on each transport block (dynamic TF parameters). The more general strategy for energy matching makes this method more useful. -14-200529590 Multi-purpose 'especially suitable for the multi-function method of code-splitting (CD Μ, that is, sending E-DC with different passwords and related 5 channels) and time-division multi-function method (TD M is to send ε-DC Η and related 5 channels with the same password in chronological order) and can even be used for other multi-function methods. This general application is advantageous because it is currently unpredictable whether CDM or TDM will be used on the E-DCH. The correlation between the energy in each information bit and the noise power density (Eb / NQ) can decisively specify the security of the transmission of a certain piece of information. In a HARQ system with a soft combination, this uses all the previously transmitted energy of a packet. The accumulated energy can now be optimized through different strategies such as explicitly setting the transmission power for each retransmitted packet. In general, the type and intensity of this energy matching effect does not depend on the number of transmissions previously sent, but on the fact that the type of HARQ and soft combination effect is performed on that physical layer. I should note that the above characteristics may be different for various transport blocks within a TTI (for example, if they originate from different transport paths). In addition, the energy matching effect may also depend on other parameters, such as depending on the commonly known soft handover at the user rate (where the subscriber can maintain connections to several base stations) and depending on the unit loading operation. Since only the network knows all such parameters, it makes sense to signal it to show the type and intensity of the energy match. In this example, this signalling operation can be performed directly or by allowing the terminal to calculate the required energy matching information. According to the conventional design, it is used from Section [2.7.2] 12 of Section 4.2.7, a transport path. The number of bits in the transport format combination j consisting of I different transport paths is -15-200529590 yuan and can be calculated by the following formula: M i, j = Z i, j_Z i- 1, j, (1) where the following relationship Would hold: Z (M = 〇 and

-平均而言使各輸送通路達成相互間的期望權重(Q0 s亦 -18- 200529590 即服務品質,例如用於單獨輸送通路之產値規格); -試圖達成最可能簡單的接收處理作業。 爲了這個運算法則的效率且爲了簡化該接收處理作業 ,較佳的是適當地修正各輸送區塊,假設只有在新近存在 有各輸送區塊之第一次傳輸時,用於無法執行任何軟性組 合的輸送通路或是用於具有軟性組合的各輸送通路。其背 景是更難對具有不同數目之輸送區塊之封包執行覆蓋,然 後必需完全開發每個輸送區塊有一個ACK/N A CK反饋的優 點。 於是可在上述輸送通路之下,爲具有嚴格QoS需求或 是更高優先權的各輸送通路配置額外的輸送區塊。另一方 面減少其輸送區塊的數目是用於具有較不嚴格之QoS需求 或是較低優先權的各輸送通路的好主意。 現在於涉及該運算法則的輸送通路中考量了各例中的 粒狀現象亦即輸送區塊大小,且因此試圖以各已傳送位元 所需要的整體能量以達成儘可能接近必要的名義能量(利 用第一能量補償產生): E n = P N Xt ττι (8) 但是同時使之不超出多過某一量額B。例如於一較佳實施 例中B = 0。 假如C C T r C Η中不存在任何可匹配的輸送通路或是存 在有無法充分匹配的輸送通路,則無法藉由功率匹配使剩餘 的能量差異均等化,或者輸送區塊的數目也會與具有軟性 組合之各輸送通路亦即新近送出重新傳輸封包的輸送通路 -19- 200529590 匹配。不過如上所述,替代地後者明顯地需要在接收處理 上付出額外的努力。雖則吾人也可以在每個輸送區塊有--個ACK/NACK反饋時執行這種替代方法,然而這只會在每 個輸送區塊送出一個ACK/N ACK且使用一種動態RM屬性 亦即分開用於每一個輸送區塊(不只是每一個輸送通路)時 耗盡其潛能。 這可藉由本身係依動態方式送出的RM屬性或是只由 動態方式送出的係數f完成,這可藉由RM使CCTrCH的 分布倍增且因此產生了有效的RM値。這個係數f對例如 對第一次傳輸而言其數値爲i且對重新傳輸而言其數値也 許是〇 . 7。 這意指能使·-輸送通路傳送出具有不同能量需求(例 如透過不同數目的重新傳輸)的輸送區塊,且儘管如此這仍 然可將所需要的能量指派給每一個區塊。不過,由於該接 收器並不清楚將以何種順序送出各輸送區塊,故本發明的 這個特定實施例很難在某些情況下進行解碼。這裡必須定 義出取決於究竟是於每個輸送通路或是每個輸送區塊上使 用一個ACK/NACK而不同的各對應規則: a)每個輸送區塊或是每組相關的輸送區塊使用··個 ACK/NACK : 可能的規則是依逐漸減小其傳輸數目的順序送出各區 塊。然後依相同的順序送出各附屬的ACK/NACK且因此可 以很容易地指派。吾人應該注意的是然後該接收處理可在 例如已對一輸送區塊進行解碼之後且在軟性組合記憶體內 -20- 200529590 出現新的輸送區塊且據此支配各附屬記憶體配置時作出更 大的努力。 爲A CK/N A CK發信號的努力可能因對每一個輸送通路 而言只允許每個TTI有m組不同之輸送區塊的事實受到限 制,亦即具有相同能主需求之”相關的”輸送區塊,例如重 新傳輸的相同數目,且因此每個輸送通路需要最大m個 ACK/NACK位元。假如在每一個特殊的時間點上出現少於 m組不同之輸送區塊,則有m個ACK/NACK位元的自由資 訊容量可供其他型式的信號發送(例如軟性ACK/NACK資 訊)之用。 b)每個輸送通路使用一個ACK/NACK: 另一種施行方法是只在能使所有輸送區塊解碼時傳送 出ACK此外傳送出NACK。這裡的缺點是具有最低累積能 量的輸送區塊(一般而言指的是傳輸次數最少的輸送區塊) 會引致該通路資源繼續保存一不必要的長時間。這裡的替 代方法是只允許有m組輸送區塊且僅將該ACK/NACK資訊 限制在傳送最頻繁的一組輸送區塊上。不過在ACK之後必 需連續傳送其他各組(甚至冒著它們業已解碼的危險)直到 ACK/NACK資訊和它們產生關聯爲止。 其處理在m = 2的特定情況下最簡單。接收器可由控制 資訊(TFCI)爲每一個輸送通路定出輸送區塊的數目η,假如 最後一次使用的H A R Q通路的k -個輸送區塊且送出一 Ν Α κ 則得知最後n-k個輸送區塊爲第一傳輸。 不過在動態使用(有效的)R Μ屬性下,吾人應該注意的 -21- 200529590 是應該只有在CCTrCH內所含之所有輸送通路具有最大 TTI長度下會改變其RM屬性。假如一 CCTrCH含有TTI 爲80毫秒的TrCH A及TTI爲20毫秒的TrCH B則其RM 屬性只有在8 0毫秒的基礎上會發生改變。於是其rm屬性 只有在所有輸送通路都開始一新T TI的時間點上出現改變 〇 不過在施行不同輸送通路的TDM下,一般會產生在未 接收到傳輸(或是在混淆了 A C K及N A C K )時該接收器不再 能正確地出各單獨輸送通路或是輸送區塊之傳輸數目的問 題。於是採用了不正確的RM屬性而引致了不再能使整體 傳輸解碼並引致失去了該CCTrCH的所有部分。到了這個 程度該方法在TDM模式上比CDM模式更能容許錯誤的存 在,因爲其中只會在錯誤事件中送出少於最佳化的功率(亦 即其規則是以太多的功率)。 當使用多通路HARQ法時,給定如上的資訊對每一個 HARQ通路而言都會成立且假定只透過一特定的HARQ通 路送出一特定的輸送區塊。 總言之,如是證明了兩種策略以對因HARQ重新傳輸 封包的結果在已改變的能量需求上影響具有NTrCH個輸送 通路的CCTrCH作出回應。第2圖可將其功率會隨著TTI 的不同(P(t1 + 1)¥ P(tl))出現陡峭變化之功率匹配的策略與 目的使功率在其名義値Pn上多少保持定常(PGmpPhpPN) 之輸送格式匹配的策略區分開。對功率匹配以及僅由一個 輸送通路(Ντκη = 1)構成的CCTrCH而言,可透過藉由爲功 -22- 200529590 率補償向量發出信號而施行的方法施行該策略。更一般化 亦即可用於NTrCH21的施行方式是利用可根據方程式(6) 定出的RM屬性。各例中係於TTI期間藉由方程式(4)定出 新近的傳送功率。輸送格式匹配的策略可在允許於重新傳 輸封包期間於該C C T r C Η內改變一輸送通路之輸送區塊數 目的方法與那些無法完成這種作業的方法之間作出區分。 該第二變型明顯地較容易施行且屬較佳的變型。 必要時可進一步於各施行方式中區分出每個輸送通路 需要一個ACK/NACK反饋以及那些在相同數目的重新傳輸 下每組輸送通路需要一個反饋的方式。其中第二種施行方 式會比第一種施行方式更複雜;取決於其應用所增加的努 力未必總是偏向有利於產生額外的益處。 第3圖顯示了一種「在於重新傳輸封包期間未改變一 輸送通路之輸送區塊數目下施行輸送格式匹配」之較佳變 型中可用運算法則的各階段。 本發明中使用了下列縮寫: CCTrCH 已編碼複合式輸送通路 CDM 密碼分割多功法 E-DCH 強化型專用通路 HARQ 混合式自動重複請求 HSDPA 高效能下行封包存取(技術) TDM 時間分割多功法 TTI 傳輸時間間隔 T r B 1 k 輸送區塊 -23- 200529590 T r C Η 輸送通路 本發明中參考了下列文件: [TR]技術幸g 告 TR 25.896(V0.3.2)版第 3GPP TSG RAN WG 1 Tdoc R1-030635號標題爲「用於U T R A F D D之已強 化上行的可行性硏究」的文件。 [J K S 0 3 ] Bang C h u 1 Jung,J a e K y u η K w ο n 和 Dan K e u n S u n g 2 0 0 3 年 4 月發表於韓國 J e j u 城之 P ι· o c e e d i n g o f V T C 2003 Spring標題爲「於HARQ體系中爲各重新傳輸封包之 M C S位準定出最佳化臨限値的方法」的論文。 [TS25 .2 1 2]技術報告 T R 2 5 · 2 1 2 版第 3 G P P T S G R A Ν 號標題爲「多功法及通路編碼法(FDD)」的文件。 [T S 2 5 . 2 1 4 ]技術幸g 告 TR 25.214 版第 3GPP TSG RAN 號標題爲「實體層的程序(F D D )」的文件。 [R 1 - 0 3 0 8 4 1 ]美國紐約三星公司於2 0 0 3年8月提出之 第 3GPP TSG RAN WG 1 Tdoc R1-030841 號標題爲「HARQ 在具有及不具有軟性組合下之性能」的文件。 【圖式簡單說明】 以下將參照各附圖利用行動無線電系統中封包導向型 資料傳輸的較佳解釋用實施例更詳盡地解釋本發明。 第1圖係用以顯小行動無線電系統中之通信的示意圖 〇 第2圖顯示的足用於具哲各NT|.CH輸送通路之CCTrCH 以回應山H A R Q重新傳輸封包造成之已改變能量需求的i ij 用策略。 -24- 200529590 第 3圖顯示的是不改變具有傳輸封包並在輸送通路 (T r C Η )內之輸送區塊的數Θ下用於進行輸送格式匹配的各 運算法則步驟。 【主要元件符號說明】 1 基 地 站 2 移 動 站 D L η、· 行 通 路 U L 上 行 通 路 ΡΕ 處 理 器 裝置 -25-(4) where tTTi stands for TTI persistence.

(X), where the neutrality can be assigned different numbers for different states (such as a lost Number, etc.) These different states are based on the state vector, for example, the state vector may contain the following elements:-the number of previous transmissions of a packet (the rule is that the number of energy losses decreases);-the HARQ and Types of soft combination action (example combination, tracking combination, full infrared and partial infrared: along with the coding gain of a function and method of the coverage-connection state (for example, S Η 〇 (soft transfer): connection and Receiving data The cover effect means that less energy can be used; however, another j-unit state can also be used within the SHO (for example, the load on each unit: given the optimal matching with the unit load in order to obtain additional capacity under the unit The time series (3) of how much higher energy path is converted for each packet can be obtained: rate matching attribute and 0 rate matching attribute takes the rate matching belonging to the previous transmission X of the packet to indicate it. For example, the demand will follow as there is no any Group's energy requirements will change); each connection of several receivers requires a type of HARQ) a high amount of energy requirements, can be at a low amount so as to be able to decode -17- 200529590 fast and safe) ; -NACK soft resource, that is, NACK will send additional information that has always or hardly received the packet from the receiver to the transmitter. I should note that the above mentioned RM matching with I = 1 is based on energy matching. In the main method, only one transmission path per TTI is exactly the same as pure power compensation, as explained at the beginning of this document. It can be modified by applying equation (4) The transmission power of each T TI will be done depending on the energy requirements of the transmission paths contained in it. However, instead, this energy exists to keep the transmission power (before power regulation) as constant as possible. Therefore, the basic The power compensation can be referenced to keep the power compensation constant. It can be expected that the interference at the base station is characterized by smaller variables and is therefore easier to predict. In this example, the available energy difference ΔE is first calculated. When all the transmission paths are sent in the previous transmission format: AE0 = PNxtm-^ ΑΕηι »⑺ /» = 1 where ρ represents the nominal transmission power without power regulation and using power compensation. If ΔΕ〇 > 〇 ', then the extra unit can be transmitted because the bit of ΔΕ〇 < 0 must be removed. However, the number of bits to be transmitted or removed may be changed only when the size of the transport blocks of each individual transport path is granular. This creates the problem of finding the algorithm that can perform the following tasks as efficiently (and simply) as possible:-change the transport format (number of transport blocks) of each individual transport path so that the transmission power P is as close as possible to ρν;- On average, each conveying channel achieves the mutual expected weight (Q0 s also -18- 200529590 is the quality of service, such as the production specifications for individual conveying channels);-Attempts to achieve the most likely simple reception processing operation. For the efficiency of this algorithm and in order to simplify the receiving processing operation, it is better to properly modify each transport block, assuming that it cannot be used to perform any soft combination only when the first transmission of each transport block has recently occurred. The conveying path is also used for each conveying path having a soft combination. The background is that it is more difficult to perform coverage on packets with different numbers of transport blocks, and then the advantage of having one ACK / NACK feedback for each transport block must be fully developed. Therefore, additional transport blocks can be configured for each transport path with strict QoS requirements or higher priority under the aforementioned transport paths. On the other hand, reducing the number of transport blocks is a good idea for transport paths with less stringent QoS requirements or lower priority. The granular phenomenon in each case, that is, the size of the transport block, is now considered in the transport path involving this algorithm, and therefore the overall energy required by each transmitted bit is attempted to achieve as close as necessary the nominal energy ( Generated with the first energy compensation): E n = PN Xt ττι (8) but at the same time it does not exceed more than a certain amount B. For example, B = 0 in a preferred embodiment. If there is no matching transmission path in CCT r C Η or there is a transmission path that cannot be fully matched, the remaining energy difference cannot be equalized by power matching, or the number of transmission blocks will be soft. Each combination of the transmission paths, that is, the transmission path of the newly transmitted retransmission packet-19-200529590 matches. As mentioned above, however, the latter obviously requires extra effort in the receiving process. Although we can also perform this alternative method when each transmission block has an ACK / NACK feedback, this will only send an ACK / N ACK per transmission block and use a dynamic RM attribute, that is, separate Used for every transport block (not just every transport path) to exhaust its potential. This can be done by the RM attribute sent by itself dynamically or by the coefficient f only sent by the dynamic mode, which can double the distribution of CCTrCH by RM and thus generate an effective RM 値. This coefficient f may be, for example, i for the first transmission and i for the retransmission. This means that the transport path can be transported out of transport blocks with different energy requirements (for example, through different numbers of retransmissions), and nevertheless the required energy can be assigned to each block. However, since the receiver does not know in what order the transport blocks will be sent out, this particular embodiment of the present invention is difficult to decode in some cases. Here, it is necessary to define the corresponding rules that are different depending on whether an ACK / NACK is used on each transport path or each transport block: a) Each transport block or group of related transport blocks is used · ACK / NACK: A possible rule is to send each block in order of decreasing its number of transmissions. Each affiliate ACK / NACK is then sent in the same order and can therefore be easily assigned. I should note that the receiving process can then be made larger, for example, after a transport block has been decoded and a new transport block appears in the soft combination memory-20-200529590 s hard work. Efforts to signal A CK / NA CK may be limited due to the fact that each TTI only allows m different sets of transport blocks per TTI, that is, "related" transports with the same main demand The same number of blocks, such as retransmissions, and therefore each transport path requires a maximum of m ACK / NACK bits. If there are less than m different transmission blocks at each particular time, there are m ACK / NACK bits of free information capacity available for other types of signaling (such as soft ACK / NACK information) . b) Use one ACK / NACK per transmission path: Another implementation method is to transmit ACK and NACK only when all transmission blocks can be decoded. The disadvantage here is that the transmission block with the lowest accumulated energy (generally, the transmission block with the least number of transmissions) will cause the channel resources to continue to be stored for an unnecessary long time. The alternative here is to allow only m sets of transmission blocks and limit this ACK / NACK information to only the most frequently transmitted set of transmission blocks. However, after the ACK, the other groups must be continuously transmitted (even at the risk that they have been decoded) until the ACK / NACK information is associated with them. Its handling is easiest in the specific case of m = 2. The receiver can determine the number of transport blocks η for each transport path by the control information (TFCI). If the k-transport blocks of the HARQ path used last time and send an Ν Α κ, we know the last nk transport areas The block is the first transmission. However, under the dynamic use of (effective) R M attributes, we should note that -21-200529590 should only change its RM attributes if all the transport channels contained in CCTrCH have the maximum TTI length. If a CCTrCH contains TrCH A with a TTI of 80 milliseconds and TrCH B with a TTI of 20 milliseconds, its RM attributes will only change on the basis of 80 milliseconds. Therefore, its rm attribute only changes at the time point when all transmission paths start a new T TI. However, under the implementation of TDM of different transmission paths, it will generally occur when no transmission is received (or ACK and NACK are confused) The receiver can no longer correctly solve the problem of the transmission number of each individual transmission path or transmission block. The incorrect RM attribute is then used, resulting in the inability to decode the overall transmission and causing the loss of all parts of the CCTrCH. To this extent, the method is more tolerant of errors in TDM mode than CDM mode, because it will only send less than optimized power in error events (that is, its rule is too much power). When the multi-channel HARQ method is used, the information given above is valid for each HARQ channel and it is assumed that a specific transmission block is sent through only a specific HARQ channel. In summary, two strategies are demonstrated to respond to the results of retransmission of packets due to HARQ affecting the CCTrCH with NTrCH transport channels on the changed energy requirements. Figure 2 shows the strategy and purpose of the power matching whose power will change steeply with different TTIs (P (t1 + 1) ¥ P (tl)) to keep the power constant at its nominal 其 Pn (PGmpPhpPN) Differentiate the transport format matching strategy. For power matching and CCTrCH consisting of only one transmission path (Nτκη = 1), this strategy can be implemented by a method implemented by sending a signal for the power -22- 200529590 rate compensation vector. More general The implementation method that can also be used for NTrCH21 is to use the RM attribute that can be determined according to equation (6). In each case, the latest transmission power is determined by equation (4) during TTI. The transport format matching strategy can distinguish between a method that allows the number of transport blocks in a transport path to be changed within the C C T r C 重新 during retransmission of a packet, and a method that cannot accomplish this task. This second modification is obviously easier to implement and is a better modification. If necessary, it can be further distinguished among the implementation methods that each transmission path needs an ACK / NACK feedback and those that require one feedback per group of transmission paths with the same number of retransmissions. The second method of implementation will be more complicated than the first method of implementation; the added effort depending on its application may not always be biased in favor of generating additional benefits.
