Description of the Invention: [Technical Field of the Invention] The present invention/step and wireless communication system. In particular, the present invention relates to a method and system for implementing Automatic Repeat Request (ARQ) assisted by Hybrid Automatic Repeat Request (H_ARQ) in a wireless communication system. [Prior Art] In the wireless communication system such as Broadband Code Division Multiple Access (WCDMA) version 5/6, 'High-speed data transmission is through High Speed Downlink Packet Access (HSDPA) and Fast Uplink Packet Access (HsupA) technology is implemented. In order to improve the reliability of data transmission, Η# was implemented. with. Figure 1 shows a conventional wireless communication system. The system 1 includes a user beta (UE) 110, a node b 12 〇, and a radio network controller (Zhe). The Η-ARQ entity is located at the media access control (L2) layer n2 of U£ii〇. And the MAC layer 122 of the Node B 120. The packet is assigned the transmission sequence number (TSN) in the H ARQ transmitter. The η-ARQ receiver receives the packet and tastes and decodes the transmitted packet. If the packet cannot be decoded, then the Η-ARQ will receive a negative acknowledgement (NACK) to the Η-ARQ transmitter to retransmit the failed packet. If the packet is decoded correctly, the H_ARQ receiver will send an acknowledgement (ACK) to the H_ARQ transmitter for the packet. When a NACK is received, 'if the number of retransmissions of the failed packet is less than the predetermined maximum, and the allowed transmission timing of the failed packet has not expired, the h_arq transmitter will retransmit the packet. The side of the lost Lin Baoshun discards the county ARQ level recovery. The ARQ entity is located at Radio Link Control (RLC) layer n4 of UE 110 and RNC 130 ❸ RLC layer 132. The ARQ entity retransmits the failed packet 4 201018130 because of the _-pair packet. In the stenciling, the class processing is prepared, and it has many options for implementing status reporting. When the H-ARQ and the Qing function coexistence system (_Ts) + _B or the long term evolution (La) evolution point B, an H-ARQ-assisted ARQ operation can be considered at this time. Figure 2 shows an example of the borrowing & H_ARQ _ 卩 operation for the 3rd Generation Partnership Project (3GPP) standard. The transmitter 25A includes an ARQ transmitter 252 and an H_arq transmitter 254. The receiver 26A includes an ARQ receiver 262 and an H-ARQ receiver 264. The H_ARQ transmitter 254 provides a local ACK or local NACK for the ARQ poller 252.
—如第2圖所示’本地NACK是在傳輸器2M無法 完成H-ARQ傳輸的時候（例如目爲最大重傳關）産生的。 ARQ傳輸器252向H-ARQ傳輸器254發送ARQ協定資料單 元(PDUX步驟2〇2 >H-ARQ傳輸器254則將這個ARQ PDU ❿ X發送到H_ARQ接收器264 (步驟204)。所述ARQ PDU X是 無法被解碼’並且H-ARQ接收器264會向H-ARQ傳輸器254 發送NACK (步驟206 )。而H-ARQ傳輸器254則向H-ARQ 接收器264重傳該ARQ PDU X (步驟208)。然而，所述ARQ PDU x仍舊是無法解碼’並且H-ARQ接收器264會向H-ARQ 傳輸器254發送另一個NACK (步驟210 )。這時，ARQ PDU x的重傳次數被確定已經達到最大重傳限度（步驟212)。於 是’ Η-ARQ傳輸器254會向ARQ傳輸器252發送關於ARQ PDUx的本地NACK (步驟214)。 201018130 此外，本地NACK也可以在H-ARQ接收器264向H-ARQ 傳輸器254報告NACK對ACK錯誤時産生。仍舊參考第2圖， ARQ傳輸器252向H-ARQ傳輸器254發送ARQ PDU y (步 驟216)。H-ARQ傳輸器254則將這個ARQ PDU y發送到 Η-ARQ接收器264 (步驟218)。ARQ PDU y無法被解碼，並 且Η-ARQ接收器264會向Η-ARQ傳輸器254發送NACK(步 驟220 )。但是’ NACK被Η-ARQ傳輸器254誤判爲是ACK， 並且Η-ARQ傳輸器254將ARQ PDU y視爲是成功傳送的。 Η-ARQ接收器264則檢測到NACK對ACK錯誤（例如在® Η-ARQ接收器264在等待PDU ARQ y重傳的同時經由相同的 Η-ARQ處理接收到新的PDU的時候X步驟222 )。所述h—arq 接收264會向H-ARQ傳輸益254發送NACK對NACK錯 誤指示符（步驟224)。一旦接收到NACK-ACK錯誤指示符， 那麼Η-ARQ傳輸器254會向ARQ傳輸器252發送本地 NACK，並且ARQ PDU y會在ARQ級得到恢復（步驟226 )。 如第2圖所示，本地ACK是在預定時序間隔中沒有發生❹ 關於ARQ封包的上述兩種事件的時候産生的。arQ傳輸器- As shown in Fig. 2, the 'local NACK' is generated when the transmitter 2M cannot complete the H-ARQ transmission (for example, the maximum retransmission). The ARQ transmitter 252 transmits an ARQ protocol data unit to the H-ARQ transmitter 254 (PDUX step 2〇2 > the H-ARQ transmitter 254 then transmits this ARQ PDU ❿ X to the H_ARQ receiver 264 (step 204). The ARQ PDU X is unable to be decoded 'and the H-ARQ receiver 264 will send a NACK to the H-ARQ transmitter 254 (step 206). The H-ARQ transmitter 254 then retransmits the ARQ PDU to the H-ARQ receiver 264. X (step 208). However, the ARQ PDU x is still unable to decode 'and the H-ARQ receiver 264 will send another NACK to the H-ARQ transmitter 254 (step 210). At this time, the ARQ PDU x is retransmitted. The number of times is determined to have reached the maximum retransmission limit (step 212). Then the 'Η-ARQ transmitter 254 sends a local NACK for the ARQ PDUx to the ARQ transmitter 252 (step 214). 201018130 In addition, the local NACK can also be in the H- The ARQ receiver 264 generates a NACK to ACK error when reporting to the H-ARQ transmitter 254. Still referring to Figure 2, the ARQ transmitter 252 transmits an ARQ PDU y to the H-ARQ transmitter 254 (step 216). H-ARQ Transmitter 254 then sends the ARQ PDU y to the Η-ARQ receiver 264 (step 218). The ARQ PDU y cannot be decoded and the Η-ARQ receives The 264 will send a NACK to the Η-ARQ transmitter 254 (step 220). However, the 'NACK is misjudged as ACK by the Η-ARQ transmitter 254, and the Η-ARQ transmitter 254 regards the ARQ PDU y as being successfully transmitted. The Η-ARQ receiver 264 detects a NACK-to-ACK error (eg, when the Η-ARQ receiver 264 receives a new PDU via the same Η-ARQ process while waiting for PDU ARQ y retransmission), step X 222) The h-arq receive 264 will send a NACK-to-NACK error indicator to the H-ARQ transmission benefit 254 (step 224). Upon receiving the NACK-ACK error indicator, the Η-ARQ transmitter 254 will forward to the ARQ transmitter. 252 sends a local NACK, and the ARQ PDU y is recovered at the ARQ level (step 226). As shown in FIG. 2, the local ACK is generated when no such event occurs in the predetermined timing interval regarding the above two events of the ARQ packet. arQ transmitter

確定在預定時序_中沒魏告NACK對ACK錯誤時（步驟 236)’H-ARQ傳輸器254會向ARQ傳輸器252發送本地ACK 6 201018130 (步驟238)。在接收到來自H-ARQ傳輸器254的本地ACK 之後，ARQ傳輸器252會從發射暫存器中丟棄該封包。It is determined that when the ACK error is not reported in the predetermined timing_ (step 236), the H-ARQ transmitter 254 transmits a local ACK 6 201018130 to the ARQ transmitter 252 (step 238). Upon receiving the local ACK from the H-ARQ transmitter 254, the ARQ transmitter 252 discards the packet from the transmit scratchpad.

If the NACK loses the ACK error indicator or the shared channel is lost due to a discontinuous transmission (DTX) / ACK error, the ARQ transmitter will not be able to recover the packet. Thus, lossless transmission is not guaranteed. The current downlink Η-ARQ (version 5) does not specify the maximum number of retransmissions of the packet. Therefore, the Η-ARQ transmitter or receiver does not know the maximum number of retransmissions per packet. It is assumed that the ARQ transmitter and the η-ARQ transmitter have the same PDU size. The Η-ARQ transmitter will inform the Η-ARQ receiver of the lost segment (not the mq PDU). If the arq pDU is retransmitted, then the h arq transmitter will be heavy (four) packets are only missing segments. In addition, it is unclear how to recover the last packet of the Η-ARQ transmission. SUMMARY OF THE INVENTION Umbrellas are involved in a method and system for implementing h_ar in a wireless communication system. The receiver determines whether an appearance occurs. H-ARQ NACK vs. ACK error. When an H_ARQ NACK pair error occurs Unless the number of retransmissions of the lost package exceeds the maximum retransmission limit, the maximum delivery timing of the failure * ^ expires and/or the failure of the seal (10) expires, ·Η-ΑΚ(^ will be H_ARQ miscellaneous n money, fine == will try to recover the failed packet. If the maximum retransmission limit, the maximum delivery time expires or the failed packet expires, then the Η-ARQ transmission sends a local NACK to the ARQ transmitter in order to recover at the ARq level. Packet. If the H-ARQ receiver does not receive a failed packet before a certain condition occurs, then the H-ARQ receiver will send a local NACK to the ARQ receiver. Based on the reception of the local NACK, the ARQ receiver can go to the ARQ transmitter. The status report is transmitted to recover the failed packet. [Embodiment] The features of the present invention can be introduced into an integrated circuit (IC) or can be configured in a circuit including a large number of interconnect elements. In accordance with the present invention, a transmission map of a process for performing an ARQ operation assisted by H-ARQ is implemented in a wireless communication system 3. The system 3 includes a transmitter 310 and a receiver 320. The transmitter 31 includes Transmitter 312 and H-ARQ transmitter 314. Receiver 320 then includes ARQ receiver 322 and H-ARQ receiver 324. To support ARQ assisted by Η-ARQ in accordance with the present invention, the following parameters are defined herein: TErrorlndicator • The H-ARQ error indication timer is defined as the timing amount of the failed packet retransmission that the H_ARQ receiver should wait before transmitting the HARQ error indicator. To make the whole system easy to implement, it is better to keep 11_person 11 ( 5 The error indicates that the timer is constant. However, the H_ARQ error indication timer can also be adjusted based on quality of service (QoS) requirements. For example, the length of the h-mq error indication timer can be related to the scheduling priority. NRetransmisskm: is a packet The maximum number of retransmissions allowed. The maximum number of retransmissions can be based on Q〇S requirements, and can be assigned 201018130 TDelivery according to each service type: after the first transmission' The maximum transfer timing allowed by the work transfer packet. The maximum transfer order can be called (10) demand (_block error rate, wait timing, etc.), and can be configured according to each service type. TRecDverySyne: opposite step h_arq Said parameter is the timing range in which the receiver receives the failed packet after communicating the H-ARQ error indicator. TR_eryAsyne: For asynchronous H_ARq, this parameter is private. The timing range in which the packet is expected to be received after the ARQ error indicator is transmitted. This timer can be associated with the q〇s requirement and can be configured per service type. For example, the length of the timer can be related to the order of the keys.
Wharq .應該接收到失敗封包的窗口（也就是封包數量）。 如果在Wharq以内沒有接收到失敗封包，則假設該封包丟失。 此外’在這裏還可以爲傳輸器310和接收器32〇提供關於 封包期限的參數（也就是傳送封包的最大時序）。這些參數可 〇 以由中心節點提供給H-ARQ接收器324以及H-ARQ傳輸器 314。如果這些參數是依照每個服務類型定義的，那麼可以在 服務開始的時候將這些參數提供給H-ARq接收器324以及 H-ARQ傳輸器314。 封包的最大重傳次數和/或期限是可以根據q〇s需求而動 態改變。所述最大重傳次數既可以通過在相關聯的發信中明確 標識傳輸次數來指示，也可以通過標識與所配置的最大傳輸次 數相關聯的MAC流來指示。依照第一種選擇，每個封包的重 傳次數是在用於首次傳輸的相關聯的控制發信中指示的。依照 201018130 第一種選擇’每一個MAC流可以與一定的重傳次數相關聯， 此外’通過在用於首次傳輸的相關聯的控制發信標識MAC 流’可以對最大傳輸次數加以指示。如果使用的是第二種選 擇’那麼所標識的MAC流將被轉換成由接收器配置的最大傳 輸次數。此外’如果將特定的H-ARQ處理專用於一組MAC 流中的某個MAC流’那麼也可以經由h-ARQ處理ID來獲知 最大重傳次數。取代地，在栢關聯的發信中還可以設置用於指 示最後一次傳輸的標記。Wharq. The window that should receive the failed packet (that is, the number of packets). If no failed packet is received within Wharq, the packet is assumed to be lost. In addition, the transmitter 310 and the receiver 32 can also be provided with parameters regarding the duration of the packet (i.e., the maximum timing of transmitting the packet). These parameters may be provided by the central node to the H-ARQ receiver 324 and the H-ARQ transmitter 314. If these parameters are defined in accordance with each service type, these parameters can be provided to the H-ARq receiver 324 and the H-ARQ transmitter 314 at the beginning of the service. The maximum number of retransmissions and/or the duration of the packet can be dynamically changed according to the demand of q〇s. The maximum number of retransmissions may be indicated either by explicitly identifying the number of transmissions in the associated transmission or by identifying a MAC flow associated with the configured maximum number of transmissions. According to a first option, the number of retransmissions per packet is indicated in the associated control transmission for the first transmission. According to the 201018130 first choice, 'each MAC stream can be associated with a certain number of retransmissions, and the maximum number of transmissions can be indicated by 'identifying the MAC stream' with the associated control for the first transmission. If the second option is used then the identified MAC stream will be converted to the maximum number of transmissions configured by the receiver. Furthermore, if a particular H-ARQ process is dedicated to a certain MAC stream in a group of MAC flows, then the maximum number of retransmissions can also be known via the h-ARQ process ID. Instead, a flag indicating the last transmission can also be set in the associated transmission of the cypress.
在下文中將會參考第3圖來描述依照本發明的借由 H-ARQ輔助的ARQ操作的處理4〇〇。H-ARQ傳輸器314向 H-ARQ接收器324發送封包（步驟402)。如果成功接收到這 個封包，那麼H-ARQ接收器324會將該封包發送到ARQ接 收器322 (在第3圖中並未顯示）。如果沒有成功接收到該封 包’那麼H-ARQ接收器324會向H-ARQ傳輸器314發送 NACK(步驟404 )。當在步驟404中發送了 NACK之後，H-ARQ 接收器324將會確定是否發生了 h_ARq NACK對ACK錯誤 (步驟406 )。一旦檢測到h-arq NACK對ACK錯誤，那麼 H-ARQ接收器324將會産生h-ARQ NACK對ACK錯誤指示 符，並且將其發送到H-ARQ傳輸器314 (步驟408)。 對同步H-ARQ傳輸來說，h-ARQ重傳時序是爲接收器所 知的。如果H-ARQ接收器324在預期重傳失敗封包的時候接 收到新的封包，除非失敗封包已被傳送了最大重傳次數，否則 H-ARQ接收器324將會確定已發生了沁从(^嫩(^對八(：〖 錯誤，並且將會發送H-ARQ NACK對ACK錯誤指示符。 201018130 對非同步H-ARQ傳輸來說，在未達到最大重傳次數時， 在H-ARQ接收器324上將會設置計時器TEiTOrIndicator，並且 H-ARQ接收器324會在步驟404中向H-ARQ傳輸器314發送 NACK。如果在計時器TErrorhldieator屆滿之前成功接收到失敗封 包，那麽計時器TErrorIndicator將會重定爲零，並且不會產生 H-ARQ NACK對ACK錯誤指示符。如果H-ARQ接收器324 在5十時器TEnOrIndieatOT屆滿之前沒有成功接收到失敗封包，那麼 φ 除非失敗封包的傳輸次數已經達到了最大重傳限制、封包最大 傳遞時序（TDeIiveiy)屆滿和/或失敗封包期限屆滿，否則η_α^ 接收器324將會確定發生了 H-ARQ NACK對ACK錯誤，並 且會向H-ARQ傳輸器314發送H-ARQ NACK對ACK錯誤指 示符。 H-ARQ NACK對ACK錯誤指示符是從H-ARQ接收器 324發送到H-ARQ傳輸器314的，它通告的是在h—arq傳輸 器314上的NACK對ACK誤判。H-ARQ NACK對ACK錯誤 ❹ 指示符與特定的H-ARQ處理以及H-ARQ處理中的特定封包 相關聯。所述H-ARQNACK對ACK錯誤指示符包含了 h_ARq 處理辨識符（ID)以及用於標識H-ARQ處理中的封包ID的 TSN。 、 對同步ARQ來說，由於可以使用失敗傳輸與錯誤報告之 間的固定時序聯繫來將H-ARQ NACK對ACK錯誤指示符與 H-ARQ處理仍以及封包TSN相關聯，因此處理扔 年TSN疋可以移除的。舉例來說，如果存在四個（4)同步 H-ARQ處理，那麼可以在發生NACK對ACK錯誤並且接收 201018130The processing of the HARQ operation assisted by H-ARQ in accordance with the present invention will be described hereinafter with reference to FIG. The H-ARQ transmitter 314 sends a packet to the H-ARQ receiver 324 (step 402). If the packet is successfully received, the H-ARQ receiver 324 will send the packet to the ARQ receiver 322 (not shown in Figure 3). If the packet is not successfully received then the H-ARQ receiver 324 will send a NACK to the H-ARQ transmitter 314 (step 404). After transmitting the NACK in step 404, the H-ARQ receiver 324 will determine if an h_ARq NACK to ACK error has occurred (step 406). Upon detecting an h-arq NACK pair ACK error, the H-ARQ receiver 324 will generate an h-ARQ NACK pair ACK error indicator and send it to the H-ARQ transmitter 314 (step 408). For synchronous H-ARQ transmission, the h-ARQ retransmission timing is known to the receiver. If the H-ARQ receiver 324 receives a new packet when it is expected to retransmit the failed packet, the H-ARQ receiver 324 will determine that a slave has occurred since the failed packet has been transmitted for the maximum number of retransmissions (^ Tender (^ to eight (: erroneous, and will send H-ARQ NACK to ACK error indicator. 201018130 For non-synchronous H-ARQ transmission, when the maximum number of retransmissions is not reached, at the H-ARQ receiver A timer TEiTOrIndicator will be set up 324, and the H-ARQ receiver 324 will send a NACK to the H-ARQ transmitter 314 in step 404. If the failed packet is successfully received before the timer TErrorhldieator expires, the timer TErrorIndicator will Reset to zero, and does not generate an H-ARQ NACK to ACK error indicator. If the H-ARQ receiver 324 does not successfully receive a failed packet before the 5th timer TEnOrIndieatOT expires, then φ unless the number of transmissions of the failed packet has been reached The maximum retransmission limit, the maximum packet transfer timing (TDeIiveiy) expires, and/or the failed packet expiration expires, otherwise the η_α^ receiver 324 determines that an H-ARQ NACK-to-ACK error has occurred. And an H-ARQ NACK pair ACK error indicator is sent to the H-ARQ transmitter 314. The H-ARQ NACK pair ACK error indicator is sent from the H-ARQ receiver 324 to the H-ARQ transmitter 314, which advertises The NACK on the h-arq transmitter 314 misjudges the ACK. The H-ARQ NACK vs. ACK error 指示符 indicator is associated with a particular H-ARQ process and a particular packet in the H-ARQ process. The H-ARQNACK pair The ACK error indicator contains the h_ARq processing identifier (ID) and the TSN used to identify the packet ID in the H-ARQ process. For synchronous ARQ, since a fixed timing relationship between the failed transmission and the error report can be used The H-ARQ NACK pair ACK error indicator is associated with the H-ARQ process and the packet TSN, so the process of throwing the TSN can be removed. For example, if there are four (4) synchronous H-ARQ processes, Then a NACK to ACK error can occur and receive 201018130
之後發送H-ARQ NACK對ACK 到TSN爲《的封包的時序 錯誤指示符。 H-ARQ NACK對ACK錯誤指示符是可以獨立於h_arq 操作的。這是通過發送肋顧魏的錯誤的接㈣序的處理 辨識符（如果需要的話）和時序偏移來實現的。取代地，h_網 NACK對ACK錯誤指示符可以作爲實體層信號而在接收到了 接收的錯誤封包之後的固定時序偏移上發送。Then send the H-ARQ NACK pair ACK to TSN as the timing error indicator of the packet. The H-ARQ NACK pair ACK error indicator can be operated independently of h_arq. This is done by sending the faulty (four) sequence of processing identifiers (if needed) and timing offsets. Instead, the h_net NACK-to-ACK error indicator can be sent as a physical layer signal on a fixed timing offset after receiving the received error packet.
如果可以從傳輸器310向接收器32〇同時發送一個以上的 封包’那麼追些封包將會具有自己的循環冗餘檢查（CRC)， 並且可以使用一個H-ARQ NACK對ACK錯誤指示符來發送 多個封包的NACK對ACK錯誤指示。由此，NACK 對ACK錯誤指示符可以包括多個處理ID、相關聯的 封包TSN和/或定時偏移。 H-ARQ NACK對ACK錯誤指示符還可以具有自己的 CRC ’以便確保可靠傳輸。這樣允許了將gc或RLC層發 信用於H-ARQ NACK對ACK錯誤指示。所述H_arq NACK ❹ 對ACK錯誤指示符封包既可以在H-ARQ級創建，也可以在 ARQ級創建。 仍舊參考第3圖’爲了確保接收到H-ARQ NACK對ACK 錯誤指示符’ H-ARQ傳輸器314可以向H-ARQ接收器324 發送ACK (步驟410)。在H-ARQ接收器324接收到來自 H-ARQ傳輸器314的ACK或者無線鏈路出現故障之前， H_ARQ接收器324可以重復發送H-ARQ NACK對ACK錯誤 指示符。 12 201018130 當在步驟4G8 t接收到H-ARQ NACK對ACK錯誤指示 符之後，除非達到最大重傳次數、最大傳遞時序屆滿㈣或失 敗封包期限屆滿，否則H-ARQ傳輸器314將會通過重傳失敗 封包來嘗試在H-ARQ級修復錯誤（步驟412)。H_ARq傳輸 器314可以向ARQ傳輸器312發送本地ACK，以便在ARQ 級恢復失敗封包（步驟414)。較佳地，只有在達到最大重傳 -人數、失敗封包的隶大傳遞時序屆滿或是失敗封包的期限屆滿 的情況下’Η-ARQ傳輸器314才會向ARQ傳輸器312發送本 地 NACK。 在現有技術中，一旦成功傳遞了封包，那麼Η-ARQ接收 器324會向Η-ARQ傳輸器314發送ACK，並且Η-ARQ傳輸 器314會向ARQ傳輸器312發送本地ACK。依照本發明，在 這種情況下，Η-ARQ傳輸器314既可以向ARQ傳輸器312發 送本地ACK，也可以不發送。 當在步驟408中發送了 η-ARQ NACK對ACK錯誤指示 ❿ 符之後，在步驟416，Η-ARQ接收器324將會確定Η-ARQ接 收器324在發生了下列條件中的至少一條件之前是否成功接 收到失敗封包： 1 ) TRec〇verySync (對應於同步 Η-ARQ 傳輸）或 TRecoveryAsync (對應於非同步Η-ARQ傳輸）已屆滿； 2) 接收到序列號比失敗封包序列號高出Wharq的新的 H-ARQ封包； 3) 達到失敗封包的最大重傳次數； 4) 計時器TDeliveiy屆滿；以及 13 201018130 5)失敗封包的期限屆滿。 如果出現前述條件中的至少一個，那麼接收器324 會向ARQ接收器322發送本地NACK (步驟418)。一旦接收 到本地NACK’ ARQ接收器322可以向ARQ傳輸器312發送 狀態報告，以便恢復失敗封包（步驟420)。在接收器 324此夠識別需要恢復的arq pdu的時候，ARQ PDU與 H-ARQ PDU之間的映射是不相關的。 在接收到來自ARQ接收器322的狀態報告之後， 傳輸器312上的ARQ暫存器可以被清空。關於失敗封包的狀響 態報告包含了關於成功接收的封包的資訊。取代地，ARQ接 收器322也可以在成功接收到N個連續封包或是計時器屆滿 之後發送狀態報告。取代地，Arq傳輸器312還可以在傳送 了暫存器中的最後一個封包之後輪詢ARQ接收器322。實施 所述輪詢的原目是射在H_ARQ峨早舰最後—個封包的 NACK對ACK錯誤。對資料流程來說’設置“用於最後一個 封包的輪詢位元”是可配置的參數。 0 爲了改善Η-ARQ傳輸中最後一個封包的恢復處理，在清 空了 Η-ARQ暫存器之後’可以從H_ARQ傳輸器314發送具 有最後一個封包指示的特殊的小封包。通過傳輸這個具有最後 個封包4曰示的特殊封包，可以確保在H_arq級上較早恢復 丟失的最後一個封包。一旦接收到這個特殊封包，接 收器324會向Η-ARQ傳輸器314反送回應。該回應封包可以 是在Η-ARQ級産生的用於指示接收到最後一個封包的新封 包。作爲選擇’該回應封包還可以通過使用似叫錯誤指示 14 201018130 封包來發送’其中該H-ARQ錯誤指示封包表示它是針對所述 小封包的回應。 取代地’爲了減小過度發信，當在H-ARQ傳輸佇列中的 最後一個資料封包調用了先前傳輸的ACK檢查之後，這時可 以發送空傳輸。空封包只包含控制資訊（也就是沒有承載）。 H-ARQ傳輸器314會在接收到H-ARQ傳輸佇列中最後一個資 料封包的H-ARQ ACK之後傳送空封包。一旦h-arq接收器 ❺ 324接收到空封包，那麼H-ARQ接收器324將會確認接收到 最後一個資料封包以及所述空封包。如果在仏^卩接收器上 沒有成功接收到最後一個封包，並且由此回應於所述最後一個 封包而發送了 NACK ’而此時最大傳輸次數尚未達到，那麽通 過接收所述空封包，可以使H-ARQ接收器324檢測NACK對 ACK錯誤。 傳輸器310和接收器320可以是WTRU、基地台或是 WCDMA、CDMA2_或第三代（3G)系統長期演進（lte) 〇 中的任何網路實體。“WTRU”包括但不局限於使用者設備 (UE)、移動站、固定或移動使用者單元、傳呼機行動電話、 個人資料助理（PDA)、電腦或是任何能在無線環境中工作的 使？者设備。而“基地台”則包括但不局限於節點B、站點控 制器、存取點或是無線環境中的其他任何類型周邊設備。 實施例 一種在無線通訊系統中用於實施借由輔助的 的方法’其中該無線通訊系統包括傳輸器和接收器，該 輸器包括H-ARQ傳輸器以及ARq傳輸器，該接收器包括 15 201018130 H-ARQ接收器以及ARQ接收器。 2 ·如實施例1所述的方法，其中包括以下步驟：h_arq 接收器確定是否發生了 H-ARQ NACK對ACK錯誤。 3·如實施例2所述的方法，其中包括以下步驟：當出現 H-ARQ NACK對ACK錯誤時’除非失敗封包的重傳次數達到 最大重傳限度、失敗封包的最大傳遞時序屆滿或者失敗封包期 限屆滿’否則H-ARQ接收器向H-ARQ傳輸器發送h_ARq NACK對ACK錯誤指示符。 4·如實施例2〜3中任一實施例所述的方法，其中 NACK對ACK錯誤指示符是與H-arq處理ω以及位在 H-ARQ傳輸器的失敗封包相關聯的。If more than one packet can be sent from the transmitter 310 to the receiver 32, then the packets will have their own cyclic redundancy check (CRC) and can be sent using an H-ARQ NACK to the ACK error indicator. The NACK of multiple packets indicates an ACK error. Thus, the NACK-to-ACK error indicator can include multiple processing IDs, associated packet TSNs, and/or timing offsets. The H-ARQ NACK may also have its own CRC' for the ACK error indicator to ensure reliable transmission. This allows the gc or RLC layer to be sent for H-ARQ NACK versus ACK error indication. The H_arq NACK ❹ packet for the ACK error indicator can be created either at the H-ARQ level or at the ARQ level. Still referring to FIG. 3' to ensure that an H-ARQ NACK pair ACK error indicator is received', the H-ARQ transmitter 314 can send an ACK to the H-ARQ receiver 324 (step 410). The H_ARQ receiver 324 may repeatedly transmit an H-ARQ NACK pair ACK error indicator before the H-ARQ receiver 324 receives an ACK from the H-ARQ transmitter 314 or the radio link fails. 12 201018130 After receiving the H-ARQ NACK pair ACK error indicator at step 4G8 t, the H-ARQ transmitter 314 will pass the retransmission unless the maximum number of retransmissions is reached, the maximum delivery timing expires (four), or the failed packet expiration period expires. The failed packet attempts to fix the error at the H-ARQ level (step 412). The H_ARq transmitter 314 can send a local ACK to the ARQ transmitter 312 to recover the failed packet at the ARQ level (step 414). Preferably, the Η-ARQ transmitter 314 transmits the local NACK to the ARQ transmitter 312 only if the maximum retransmission-number of people, the burst transfer timing of the failed packet expires, or the expiration of the failed packet expires. In the prior art, upon successful delivery of the packet, the Η-ARQ receiver 324 will send an ACK to the Η-ARQ transmitter 314 and the Η-ARQ transmitter 314 will send a local ACK to the ARQ transmitter 312. In accordance with the present invention, in this case, the Η-ARQ transmitter 314 may either transmit a local ACK to the ARQ transmitter 312 or may not transmit. After the η-ARQ NACK pair ACK error indication is transmitted in step 408, the Η-ARQ receiver 324 determines in step 416 whether the Η-ARQ receiver 324 has occurred before at least one of the following conditions Successfully received a failed packet: 1) TRec〇verySync (corresponding to synchronous Η-ARQ transmission) or TRecoveryAsync (corresponding to asynchronous Η-ARQ transmission) has expired; 2) Received sequence number higher than Wharq of failed packet sequence number New H-ARQ packet; 3) Maximum number of retransmissions to reach the failed packet; 4) Timer TDeliveiy expires; and 13 201018130 5) The expiration of the failed packet expires. If at least one of the foregoing conditions occurs, the receiver 324 sends a local NACK to the ARQ receiver 322 (step 418). Upon receipt of the local NACK' ARQ receiver 322, a status report can be sent to the ARQ transmitter 312 to recover the failed packet (step 420). The mapping between the ARQ PDU and the H-ARQ PDU is irrelevant when the receiver 324 is able to identify the arq pdu that needs to be recovered. After receiving the status report from the ARQ receiver 322, the ARQ register on the transmitter 312 can be emptied. The report on the failure packet contains information about the packets that were successfully received. Alternatively, ARQ receiver 322 may also send a status report after successfully receiving N consecutive packets or expiring the timer. Alternatively, Arq transmitter 312 can also poll ARQ receiver 322 after transmitting the last packet in the scratchpad. The original purpose of implementing the polling is the NACK-to-ACK error of the last-packet of the H_ARQ峨 early ship. For the data flow, 'Setting the polling bit for the last packet' is a configurable parameter. 0 In order to improve the recovery process of the last packet in the Η-ARQ transmission, a special small packet having the last packet indication may be transmitted from the H_ARQ transmitter 314 after the Η-ARQ register is cleared. By transmitting this special packet with the last packet 4, it is ensured that the last lost packet is recovered earlier on the H_arq level. Upon receiving this special packet, the receiver 324 will send a response back to the Η-ARQ transmitter 314. The response packet may be a new packet generated at the Η-ARQ level to indicate receipt of the last packet. Alternatively, the response packet may also be sent by using a packet-like error indication 14 201018130 packet where the H-ARQ error indication packet indicates that it is a response to the small packet. Instead of reducing the excessive signaling, when the last data packet in the H-ARQ transmission queue invokes the previously transmitted ACK check, an empty transmission can be sent at this time. Empty packets contain only control information (that is, no bearers). The H-ARQ transmitter 314 will transmit an empty packet after receiving the H-ARQ ACK of the last data packet in the H-ARQ transmission queue. Once the h-arq receiver 324 receives the empty packet, the H-ARQ receiver 324 will acknowledge receipt of the last data packet and the empty packet. If the last packet is not successfully received on the receiver, and thus the NACK is sent in response to the last packet, and the maximum number of transmissions has not been reached at this time, then by receiving the empty packet, it can be made The H-ARQ receiver 324 detects a NACK to ACK error.
