M314881 八、新型說明: 【新型所屬之技術領域】 本發明係與無線通信系統有關,尤其是關於在用於演進 型通用陸地無線電存取(E-UTRA)的上行鏈路(UL)'單 載波分頻多重存取(SC-FDMA)中排程並多工通道品質指 標(CQI)以及肯定應答/否定應答(ACK/NACK)反饋。曰 【先前技術】 目前,3GPP和3聊2都在考慮長期演進專案,在這些 專案中,無線電介面和網路架構的演進都是必需的。目前, SC_FDMA已經爲E-UTRA的上行鏈路所採用,而正交分 頻多重存取(0FDMA)則爲下行鏈路所採用。 , B節點(Node B)使用用戶設備(UE)測得的下行鏈路 .CQ1來排程下行鏈路共用資料通道。在解碼了下行鏈路資 -料傳輸之後,UE需要向Node B發送反饋(例如 ^ ACK/NACK),以向Node B告知相應的HARQ傳輸是否 成功。上行鏈路傳輸格式資訊以及HARQ資訊被稱爲上行 鍵路數據相關控制資訊。另一方面’用於下行鏈路資料傳 ,的CQI和ACK./NACK被稱爲上行鏈路數據不相關控制 貝成。在E-UTRA系統,一需要解決的問題是如何對經由 瓜通道進行的下行鏈路卿和ack/nack的報告進行排M314881 VIII. New Description: [New Technical Field] The present invention relates to a wireless communication system, and more particularly to an uplink (UL) 'single carrier for Evolved Universal Terrestrial Radio Access (E-UTRA) Scheduled and multiplexed channel quality indicator (CQI) and positive acknowledgement/negative acknowledgement (ACK/NACK) feedback in crossover multiple access (SC-FDMA).曰 [Prior Art] Currently, both 3GPP and 3 Chat 2 are considering long-term evolution projects. In these projects, the evolution of the radio interface and network architecture is required. Currently, SC_FDMA is already used for the uplink of E-UTRA, and Orthogonal Frequency Division Multiple Access (OFDM) is used for the downlink. The Node B (Node B) uses the downlink (CQ1) measured by the User Equipment (UE) to schedule the downlink shared data channel. After decoding the downlink resource transmission, the UE needs to send feedback (e.g., ^ ACK/NACK) to the Node B to inform the Node B whether the corresponding HARQ transmission is successful. The uplink transmission format information and the HARQ information are referred to as uplink data related control information. On the other hand, CQI and ACK./NACK for downlink data transmission are referred to as uplink data irrelevant control. In the E-UTRA system, one problem that needs to be solved is how to report the downlink and ack/nack reports via the melon channel.
程。爲了方便起見,傳送CQI的UL通道被稱爲UL CQICH’而傳送ACK/NACK的肌通道則被稱爲ul ACKCH。 在現有技術的高速下行鏈路封包存取 (HSDPA)中, M314881 爲UE分配專用的低資料速率通道,以將cQI連同 ACK/NACK —起報告給Node B ’並且該專用通道總是爲 UE所獨孕的。然而,如果使用專用通道來傳送cqi以及 ACK/NACK,那麼可以同時支援的UE的數量將會受到限 制0 【新型内容】Cheng. For convenience, the UL channel transmitting the CQI is referred to as UL CQICH' and the muscle channel transmitting the ACK/NACK is referred to as ul ACKCH. In the prior art High Speed Downlink Packet Access (HSDPA), the M314881 allocates a dedicated low data rate channel for the UE to report the cQI along with the ACK/NACK to the Node B 'and the dedicated channel is always the UE Only pregnant. However, if a dedicated channel is used to transmit cqi and ACK/NACK, the number of UEs that can be simultaneously supported will be limited to 0. [New content]

The reflection includes the channel quality indicator of the downlink data received by the lin and the ACK/NACK. Moreover, for efficient transmission, the feedback can be multiplexed in a variety of ways. The scheduling procedure may include: scheduling periodic feedback reports, determining the location of the UL channel for feedback reporting, and signaling the location of the UL channel to the top signal and the feedback reporting period. • The gas work plan 2 selection is based on at least one of the following: • No downlink data is transmitted to the UE in the previous subframe, 3 is not transmitted in the current subframe. ULf, and = No: Q: Bit 70 is configured to be transmitted in the current subframe. Different scenarios are disclosed based on a combination of the foregoing determinations. In these schemes, each scheme can be used to select the user's equipment (the UE is selected by the implementer for the wireless communication system and the township feedback report. And the NodeBiUE includes; the first transmitter communicating with the first processor/receiving the first antenna connected to the first transmitter/receiver; and the first processor M314881 and the multiplexer a feedback generator for communicating, the feedback generator for generating feedback based on the received downlink data; and a first multiplexer in communication with the first processor, the first multiplexer for generating feedback from the feedback Feedback is multiplexed with other uplink data. The N-B includes a second processor; a buffer in communication with the second processor, the buffer storing data to be transmitted to the UE; and a second transmitter/receiver communicating with the second processor a second antenna coupled to the second transmitter/receiver; a second multiplexer in communication with the second processor; and a scheduler in communication with the second processor and the first transmitter/receiver The scheduler is for scheduling an uplink feedback channel; and a transmitting device for communicating with the scheduler, the mapping device for mapping resource blocks from the downlink communication to an uplink feedback channel location. [Embodiment] $Home Equipment (UE) "includes but not limited to == early jWTRU", mobile station, fixed or mobile use two telephone, personal digital assistant (pda), electric fine or 疋 operate in wireless environment The term "base station (BS)" is used to slap Hong L, his device. The following is a reference to a 丨 - 仏 仏 ... including but not limited to Node Β, site control, access point or wireless ring ULCCHCH The short row of m is the other side-by-side device. ^This is a total of Xiaotongxin in the unified financial SC_FDMA to transmit CQJ based on the useless system. CQICH system. First, #彳图 shows - for row, , Whether there is any data for the UE in the buffer of N〇de B (step 1〇2). If there is no M314881 in the buffer, the method will wait in step 1〇2 until the buffer There is information. When there is no data for the UE in the buffer of the standby Node B, the uplink CQICH does not need to be scheduled. If there is data in the buffer of the Node B, the CQI report is advertised in the busy side of the secondary message ( Step 1〇4). As described in more detail in connection with Figures 3 and 4, in accordance with the implementer Any value of N may be equal to or greater than 1 and not more than 5 stupid or 10 - the value of the mobility values of the UE .N
: 相關聯’ UE的移動性越高,N的值應該越低。在用於UE 的第下行鏈路(DL)資料傳輸之前,Node B對CQI報告以 及UL CQICH進行排程。UL CQICH則被配置成在每n個 副訊框中傳送一次。 UL CQICH的位置(按時間和頻率)應該爲NodeB以 •及UE所知。預先定義的時間和頻率跳頻圖案可被應用於: The higher the mobility of the associated 'UE', the lower the value of N should be. The Node B schedules the CQI report and the UL CQICH before the downlink (DL) data transmission for the UE. The UL CQICH is configured to transmit once every n subframes. The location of the UL CQICH (by time and frequency) should be known to the NodeB and to the UE. Predefined time and frequency hopping patterns can be applied
所排耘的ULCQICH位置(步驟1〇6)。用於獲知ulcqICH -位置的一種例示方式是當Node B排程CQI報告時,由該The ranked ULCQICH location (steps 1〇6). An exemplary way to learn ulcqICH-location is when the Node B schedules a CQI report.
NodeB向UE發送信號明確告知ULCQICH位置。預先定The NodeB sends a signal to the UE to explicitly inform the ULCQICH location. Predetermined
義的時間和頻率跳頻圖案可以被應用於所排程的UL CQICH位置’以實現更好的時間和頻率分集。由於N〇(je b 和UE知道UL CQICH位置,因此在UL CQICH上不必傳 送 UE ID 〇 在一或多個資源區塊内部,UE的CQI位元可以採用若 干種可行的方法而與ACK/NACK資訊、及/或同一 UE的 UL資料相關控制資訊以及用戶資料、及/或其他ue的UL 控制資訊以及用戶資料進行多工。 M314881 接收器(也就是Node B)需要UL導頻來解碼ul CQICH。因此,用於UL CQICH的瓜導頻同樣是需要分 配ULCQICH的。如果使用的是基於分頻多工(fdm)的 UL導頻,那麼應該分配1;1^導頻位置(在頻域中)。如果 使用的是基於分崎多工(CDM)的UL導頻,則應該分配 UL導頻循%移位以及頻域位置(可選)。基於導頻 - 的一實例是基於恆定幅零自相關(CAZAC)序列的導頻》 , 用於UL CQICH的UL導頻上的資訊是與UL Cqich 一起 明確用信號通知的。或者是,在一或多個資源區塊内部的 ULCQICH位置(在時域和頻域中)與用於ULcqich的 UL導頻之間也可以使用一預先定義的映射。因此,在這裏 疋不存在傳彳s開銷的。爲了更南的靈活性,該預先定義的 映射可以經由廣播信號或是控制通道來重新配置。 : 在1^^接收到來自UE的CQI反饋之後,如和6會 開始排程在DL共用資料通道上的DL資料傳輸。爲UE的 • DL資料傳輸的排程模式是可以動態改變的。可行的排程模 式則包括分散式、集中式、ΜΙΜΟ (封閉迴路或開放迴路) 以及非ΜΙΜΟ,以及這些模式的可能組合。不同的排程模 式需要不同的CQI反饋量,例如整個頻寬的平均C(^、組 塊(chunk)中的Κ個最佳<:φ、支援封閉迴路或開放迴路 ΜΙΜΟ的CQI等等。因此,與不同的反饋量相對應的 不同的ULCQICH應該進行相應的定義以及分配/排程。 當Node B在不同排程模式之間切換時,在封包呼叫期 間可以動態地重新配置UL CQICH。在將模式重新配置成 M314881 集中式、分散式、ΜΙΜΟ等時,舉例來說,這時可使用廣 播通道來歧配置/重新配置。當各胞元制公共模式或是 用戶在-胞元中使用相同模式時,這時可以實現上述方 案。但是’當使用混合方案時,也就是說The time and frequency hopping pattern can be applied to the scheduled UL CQICH position' to achieve better time and frequency diversity. Since N〇(je b and UE know the UL CQICH location, it is not necessary to transmit the UE ID in one or more resource blocks on the UL CQICH, the CQI bit of the UE can adopt several feasible methods with ACK/NACK Information, and/or UL data related control information and user data of the same UE, and/or other ue UL control information and user data are multiplexed. M314881 Receiver (ie Node B) requires UL pilot to decode ul CQICH Therefore, the pilot pilot for UL CQICH is also required to allocate ULCQICH. If a frequency-based multiplex (fdm)-based UL pilot is used, then 1; 1^ pilot position should be allocated (in the frequency domain) If you are using a Chisa-based Duplex (CDM)-based UL pilot, you should assign the UL pilot to % shift and the frequency domain position (optional). An example based on pilot-based is based on constant amplitude zero. The pilot of the autocorrelation (CAZAC) sequence, the information on the UL pilot for the UL CQICH is explicitly signaled together with the UL Cqich, or the ULCQICH location within one or more resource blocks (in Time domain and frequency domain) with UL for ULcqich A pre-defined mapping can also be used between frequencies. Therefore, there is no overhead in the transmission. For more flexibility, the predefined mapping can be reconfigured via broadcast signals or control channels. After receiving the CQI feedback from the UE, the DL data transmission scheduled on the DL shared data channel will start to be scheduled as in 6. The schedule mode for the DL data transmission of the UE can be dynamically changed. Scheduling modes include decentralized, centralized, ΜΙΜΟ (closed loop or open loop) and non-ΜΙΜΟ, and possible combinations of these modes. Different scheduling modes require different amounts of CQI feedback, such as the average C of the entire bandwidth ( ^, the best of the chunks <: φ, CQI supporting closed loop or open loop 等等, etc. Therefore, different ULCQICH corresponding to different feedback quantities should be defined and allocated accordingly / Schedule. When the Node B switches between different scheduling modes, the UL CQICH can be dynamically reconfigured during the packet call. Reconfigure the mode to M314881 centralized In the case of decentralized, decentralized, etc., for example, a broadcast channel can be used to configure/reconfigure at this time. When each cell public mode or the user uses the same mode in the cell, the above solution can be implemented. But 'when using a hybrid solution, that is to say
,如果每一 UE 《連接在胞το中具有不同的模式,那麽應該使用某些共用 控制通道來動態重新配置操作或排程模式。在這種情況 _ 下,關於模式的資訊(1〜3位元)應該在共用控制通道中 • 傳送和承載。此外,也可以經由RRC傳信而以-種較慢的 方式完成重新配置。If each UE "connected" has a different mode in cell το, then some shared control channels should be used to dynamically reconfigure the operation or scheduling mode. In this case _, information about the mode (1 to 3 bits) should be transmitted and carried in the shared control channel. In addition, reconfiguration can also be done in a slower manner via RRC signaling.
在使用混合模式而使某些UE具有分佈模式、某些UE 具有集中模式以及某些UE具有MIM0模式時,排程將會 變得更爲複雜。因此,這時必須使用排程演算法來有效應 對“混合”情況。 在將U L C QIC Η位置通信給u E之後,判定是否成功地 將NodeB的緩衝器中的所有資料傳送到UE (步驟1〇8)。 _ 如果沒有成功傳送完所有資料,則重復執行步驟1〇8,直 至成功傳送了所有資料爲止。一旦成功傳送了 N〇de B的缓 衝器中所有用於UE的資料,則N〇deB釋放(deall〇cate) UL CQICH (步驟11〇),並且方法1〇〇將藉由檢查來重復 觀察NodeB的緩衝器中是否存在資料(步驟1〇2)。Scheduling will become more complicated when using hybrid mode with some UEs having a distributed mode, some UEs with a centralized mode, and some UEs with MIM0 mode. Therefore, you must use a scheduling algorithm to have an effect on the "mixed" situation. After the U L C QIC Η position is communicated to u E, it is determined whether all the data in the buffer of the NodeB is successfully transmitted to the UE (step 1 〇 8). _ If all the data has not been successfully transferred, repeat steps 1〇8 until all the data has been successfully transferred. Once all the data for the UE in the buffer of N〇de B is successfully transmitted, N〇deB releases (deall〇cate) UL CQICH (step 11〇), and method 1〇〇 repeats observation by inspection. Whether there is data in the buffer of the NodeB (step 1〇2).
UL ACKCH 較佳地’共用通道將被用於在UL SC-FDMA中以基於 無爭用的方式來傳送用於DL資料傳輸的ACK/NACK反 饋。第2圖顯示了一種用於排程ul ACKCH的方法200。 M314881 於此二判定是否存在用於仙的DL資料傳輸(步驟2〇2)。 如又有用於UE的DL傳輸,則方法200會在步驟202 中等待/直至有待發送到UE的DL資料。在沒有用於UE 的DL資料傳輸時,這時是不需要排程UL ACKCH的。 如果有待發送到UE的DL資料,則在發送了 DL資料 之後排程UL ACKCH (步驟204)。在N〇deB所排程的每 ' 一 DL資料傳輸與相應的ACK/NACK反饋之間需要一固定 ψ 時序/厘個副訊框)。並且在-較佳實施方式中,M=l。 獲取ULACKCH位置(步驟206),並且會向UE發送 具有ULACKCH位置的信號(步驟2〇8),然後該方法將The UL ACKCH preferably' shared channel will be used to transmit ACK/NACK feedback for DL data transmission in UL SC-FDMA in a contention free manner. Figure 2 shows a method 200 for scheduling ul ACKCH. M314881 determines whether there is a DL data transmission for Xian (step 2〇2). If there is another DL transmission for the UE, the method 200 will wait in step 202 until the DL data to be transmitted to the UE. When there is no DL data transmission for the UE, there is no need to schedule UL ACKCH at this time. If there is a DL data to be transmitted to the UE, the UL ACKCH is scheduled after the DL data is transmitted (step 204).

會結束(步驟210)。對Node B和UE來說,UL ACKCH 位置(在時域和頻域中)應該是已知的。有兩種方法可獲 取s亥UL ACKCH位置。第一種是經由顯性傳信,在這種情 -況下,一旦獲取了 UL ACKCH位置,那麼Node B會在每 一所排程的DL·資料傳輸中將ULACKCH位置直接發送到 _ UE (也就是說,步驟208是緊隨步驟206的)。 第二種獲取UL ACKCH位置的方法是藉由將DL資料 傳輸所使用的資源區塊映射到UL ACKCH位置(步驟 212)。該映射則應該經由廣播通道(BCH)傳送到UE。 可選擇地,預先定義的時間和頻率跳頻圖案同樣可以應用 於该映射(步驟212,如虛線輪廊所不)。這樣則可以爲 ULACKCH實現更好的時間和頻率分集。 如果DL資料傳輸使用了 K個資源區塊(對於所有大於 1的K),那麼ULACKCH位置可以採用兩種映射方式: 11 M314881 1 · UL ACKCH使用該DL資料傳輸所使用的第k (l$k$K)個資源區塊映射的位置。 2 · IJL· ACKCH使用由κ個資源區塊所映射的位置的置 換(permutation)。舉例來說,供dl資料傳輸使用的可 以是三資源區塊。對第一傳輸來說,ACK/NACK是在第二 資源區塊所映射的位置上傳送的。對第二(重新)傳輸來 說’ ACK/NACK是在第三資源區塊所映射的位置上傳送 的。對第三(重新)傳輸來說,ACK/NACK是在第一資源 區塊所映射的位置上傳送的,依此類推。 由於NodeB和UE都是知道ULACKCH位置,因此, 在UL ACKCH上不必傳送UE ID。 在一或多個資源區塊内部,UE的ACK/NACK資訊可 以採用若干種可行方法而與CQI位元、及/或同一 UE的 UL資料相關控制資訊以及用戶資料、及/或其他ue的UL 控制資訊以及用戶資料進行多工。接收器(也就是NodeB) 需要UL導頻來解碼ULACKCH。因此,用於ULACKCH 的UL導頻同樣是需要分配ULACKCH的。如果使用的是 基於FDM的UL導頻,那麼應該分配的是UL導頻位置(在 頻域中)。如果使用基於CDM的UL導頻(例如基於CAZAC 的導頻),則應該分配UL導頻循環移位以及頻域位置(可 選)。 在一較佳實施方式中,所使用的是一資源區塊内部的 ULACKCH位置(在時域和頻·域上)之間的預先定義的映 射,並且UL導頻則被用於UL ACKCH。因此,這其中是 12 M314881 不存在傳信開銷的。 ΰίΑ料不相關控制眘訊的多工 較佳地,如上該,UL CQICH被配置成在每Ν個副訊 才[上傳送一次。依據Ν的值是否大於1,可以使用UL·資 料獨立控制資訊的不同多工。 •tiHQI配置成在每個副訊框發摄及饋時的多工 、夕第3圖顯示的是當C(3I報告週期N等於一副訊框時用 ;夕工的方法300。先判定是否在先前副訊框中向UE傳送 ^DL資料(步驟3〇2)。如果在先前副訊框中沒有dl資 ,傳送到UE,則判定是否在目前副訊框中向uE傳送了 UL資料(步驟304)。 如果在目前副訊框中沒有傳送到UE的UL資料,則應 範m (步驟306)。在範例i中,CQi位元在預先 :=LCQICH上傳送。該預先定義的uLC_可以 的瓜:"1任何資源區塊中,甚至在用於其他UE W UL貝枓傳輸的資源區塊内多工。 = 資料(步驟 則應用多工摩巳例2 (步驟、 中存在用於多工的兩互斥選擇例2中,其 預先定義的UL CQICH上傳送。2Α中’邮位元在 費資源;然而與選擇2Β二並未浪 銷。 輝2Α具有更多的導頻開 在選擇2Β中,CQI位元在爲η ;^E ^ ^ t.4 像术,CQI位元與同 13 M314881 一 UE的UL資料相關控制位元以及用戶資料進行多工。與 選擇2A相比,選擇2B沒有導頻開銷;但是UE的資 料速率將會降低。由於UL共用資料傳輸並不總是存在的, 因此仍舊需要分配預先定義的UL CQICH。除非Node B分 配其他UE在這些資源上傳送,否則預先定義的UL cqich 的資源將被浪費,而該分配會使NodeB的排程更爲複雜。 可選擇的,Node B可以將預先定義的UL CqICH的資源分 配給其他UE ’以進行傳輸。 如果在先前副訊框中存在傳送到UE的DL資料(步驟 302),則判定在目前副訊框中是否有傳送到1;£的1;[資 料(步驟310)。如果在目前副訊框中沒有傳送到1;£:的 UL資料,則應用範例3 (步驟312)。在範例3中,其中 有三種互斥選擇。 〃 在選擇3A中,用於DL資料傳輸的ACK/NACK在預 先疋義的UL CQICH上與CQI位元一起傳送。與選擇3c 相比,這種選擇節省了導頻開銷。由於UL CQICH總是可 用的,因此,沒有必要單獨分配UL ACKCH。但是,該預 先定義的UL CQICH必須被配置的足夠大,以傳送 ACK/NACK資訊。在沒有傳送ACK/NACK時,資源將被 浪費。 在選擇3B中,CQI資訊與ACK/NACK —起在UL ACKCH上傳送。UL ACKCH可位於由Node B所配置的任 何資源區塊上,甚至在用於其他UE的UL資料傳輪的資源 區塊内進行多工。與選擇3C相比,選擇3B節省了導頻開 M314881 銷。如果沒有正確解碼DL共用控制通道(DL-SCCH), 那麽將不會傳送ACK/NACK (因爲UE不知道在先前副訊 框中是否存在DL資料傳輸)。在這種情況下,Node B認 爲CQI位元與ACK/NACK —起在預先定義的UL ACKCH 上傳送。然而ACK/NACK卻並未傳送,而這將會産生一問 題。儘管如此,由於ACKCH並不總是可用的,因此仍需 分配預先定義的UL CQICH。除非Node B分配其他UE在 這些資源上傳送,否則預先定義的UL CQICH的資源將被 浪費,而該分配會使Node B的排程更爲複雜。可選擇的, Node B可以將預先定義的UL CQICH的資源分配給其他 UE,以進行傳輸。 在選擇3C中,ACK/NACK與CQI是分開傳送的。也 就是說,ACK/NACK在UL ACKCH上傳送,而CQI位元 則在預先定義的UL CQICH上傳送。對選擇3c來說,在 UL CQICH上並未浪費資源;但是與選擇3入和3B相比, 其導頻開銷將會更多。 如果在目别副訊框中存在傳送到UE的UL資料(步驟 310),則應用範例4 (步驟314)。在範例4中,存在用 於多工的四互斥選擇。在選擇4八中,ack/Nack和cqi 位元在爲同_UE的UL共用:資料傳輸所排程的資源區塊内 一起傳送。這樣一來,ACK/NACK以及CQI位元與同一 UE的UL資料相關控制位元以及用戶資料相進行多:。選 擇4A沒有導頻開銷;但是,UE的UL #料速率將會降低。 由於UL共用資料傳輸並不總是存細,因此仍需9分配預 15 ( M314881 先定義的ULCQICH(以及可能的UL ACKCH)。除非Node B分配其他UE在這些資源上傳送,否則預先定義的UL CQICH (以及ULACKCH,如果有)的資源將被浪費,而 該分配會使Node B的排程更爲複雜。可選擇地,Node B 可以將預先定義的ULCQICH (以及ULACKCH,如果有) 的資源分配給其他UE,以進行傳輸。 在選擇4B中,用於DL資料傳輸的ACK/NACK在預先 定義的UL CQICH上與CQI位元一起傳送。與選擇4D相 比,選擇4B具有較少的導頻開銷,但是與選擇4A相比, 選擇4B則具有更多的導頻開銷。由於ul CQICH總是可 用的,因此,在這裏沒有必要分配UL ACKCH,並且UE 的UL資料速率將不會降低。但是,該預先定義的ul CQICH必須被配置的足夠大,以傳送ACK/NACK資訊。 當沒有傳送ACK/NACK時,資源將被浪費。 在選擇4C中,CQI資訊與ACK/NACK資訊一起在預 先定義的UL ACKCH上傳送。與選擇4D相比,選擇4C 具有較低的開銷,但是與選擇4A相比,選擇4C具有較高 的導頻開銷。UE的UL資料速率將不會降低。選擇4C的 其他缺陷係與範例3中的選擇3B的缺陷是相同的。 在選擇4D中,ACK/NACK以及CQI是分開傳送的。 也就是說,ACK/NACK在預先定義的UL ACKCH上傳送, 而CQI位元則在預先定義的ULCQICH上傳送。對選擇4D 來說,在UL CQICH和UL ACKCH上並未浪費資源。UE 的UL資料將不會降低。但是與選擇4A、4B以及4C相比, M314881 選擇4D具有更高的導頻開銷。 此外’ UL資源請求(稱爲“排程資訊,,)位元既可以 在同- UE的UL CQICH或UL ACKCH上傳送,也可以在 為同-UE的UL共用資料傳輸所排程的資源區塊中一起傳 送。相應地,UL CQICH或UL ACKCH需要被配置的足夠 大,以與UL資源請求位元相適應。或者,在爲同一 ue 的UL /、用負料傳輸所排程的資源區塊中需要保留uL資源 請求位元的數量。 ' 皇於每個副訊框的_蓮差J^COI鉬丢時沾客丁_ 第4圖顯示的是當CQI報告週期N大於—副訊框時用 =多工的方法働。先判定在切的副訊框中是否存在傳 运到UE的任何Dl資料(步驟4〇2)。如果在先前副訊框 中沒有傳送到UE的DL資料’則判定在目前副訊框中是否 有傳送到UE㈣L·(㈣4〇4)。如果在目前的副訊 Π中’又有傳送到UE的UL資料,則判定是否將观位元It will end (step 210). For Node B and UE, the UL ACKCH location (in the time and frequency domains) should be known. There are two ways to get the sig UL ACKCH position. The first is via explicit signaling. In this case, once the UL ACKCH location is acquired, the Node B will send the ULACKCH location directly to the _ UE in each scheduled DL data transmission ( That is, step 208 is followed by step 206). The second method of obtaining the UL ACKCH location is by mapping the resource blocks used for DL data transmission to the UL ACKCH location (step 212). This mapping should then be transmitted to the UE via the Broadcast Channel (BCH). Alternatively, a predefined time and frequency hopping pattern can be applied to the mapping as well (step 212, as indicated by the dashed circle). This allows for better time and frequency diversity for ULACKCH. If DL data transmission uses K resource blocks (for all Ks greater than 1), then the ULACKCH location can be mapped in two ways: 11 M314881 1 · UL ACKCH uses the kth (l$k) used for the DL data transmission $K) The location of the resource block map. 2 · IJL· ACKCH uses the permutation of the locations mapped by the κ resource blocks. For example, the three resource blocks can be used for dl data transmission. For the first transmission, the ACK/NACK is transmitted at the location mapped by the second resource block. For the second (re)transmission, the ACK/NACK is transmitted at the location mapped by the third resource block. For the third (re)transmission, the ACK/NACK is transmitted at the location mapped by the first resource block, and so on. Since both the NodeB and the UE know the ULACKCH location, it is not necessary to transmit the UE ID on the UL ACKCH. Within one or more resource blocks, the ACK/NACK information of the UE may use several feasible methods to control information related to the CQI bit, and/or the UL data of the same UE, as well as user data, and/or other ue UL. Control information and user data for multiplex. The receiver (ie, NodeB) requires UL pilots to decode the ULACKCH. Therefore, the UL pilot used for ULACKCH is also required to allocate a ULACKCH. If an FDM-based UL pilot is used, then the UL pilot position (in the frequency domain) should be allocated. If a CDM-based UL pilot (e.g., a CAZAC-based pilot) is used, the UL pilot cyclic shift and the frequency domain position (optional) should be allocated. In a preferred embodiment, a predefined mapping between ULACKCH locations (on the time domain and frequency domain) within a resource block is used, and the UL pilot is used for the UL ACKCH. Therefore, this is 12 M314881 there is no transmission overhead. ΰ Α Α 不 控制 控制 控制 较佳 较佳 较佳 较佳 较佳 较佳 较佳 较佳 较佳 较佳 较佳 较佳 较佳 较佳 较佳 较佳 较佳 较佳 较佳 较佳 较佳 较佳 较佳 较佳 较佳 较佳 较佳 较佳 较佳 较佳 较佳 较佳 较佳Depending on whether the value of Ν is greater than 1, different multiplexes of information can be independently controlled using UL. • tiHQI is configured to be multiplexed in each sub-frame transmission and feed, and the third picture shows when C (3I report period N is equal to one sub-frame; the method of Xigong is 300. First determine whether Transmitting the ^DL data to the UE in the previous subframe (step 3〇2). If there is no dl in the previous subframe, transmitting to the UE, it is determined whether the UL data is transmitted to the uE in the current subframe ( Step 304) If there is no UL data transmitted to the UE in the current subframe, it should be m (step 306). In the example i, the CQi bit is transmitted on the pre:: LCQICH. The predefined uLC_ Can be melon: "1 in any resource block, even in the resource block for other UE W UL Bellow transmission. = Data (steps apply multiplex case 2) In the multiplexed two mutually exclusive selection example 2, its pre-defined UL CQICH is transmitted. In the 2 ' 'the postal unit is in the fee resource; however, the selection is not the same as the selection 2. The Α2Α has more pilots. In the selection 2Β, the CQI bit is in the η; ^E ^ ^ t.4 image, the CQI bit and the 13 M314881 one UE UL data related control bit User data is multiplexed. Compared to selecting 2A, there is no pilot overhead for selecting 2B; however, the data rate of the UE will be reduced. Since UL shared data transmission does not always exist, it is still necessary to allocate a predefined UL CQICH. Unless the Node B allocates other UEs to transmit on these resources, the resources of the predefined UL cqich will be wasted, and the allocation will make the scheduling of the NodeB more complicated. Alternatively, the Node B can pre-define the UL CqICH. The resources are allocated to other UEs for transmission. If there is DL data transmitted to the UE in the previous subframe (step 302), it is determined whether there is a transmission to 1 in the current subframe: 1; (Step 310) If the UL data of 1; £: is not transmitted in the current subframe, then Example 3 is applied (Step 312). In Example 3, there are three mutually exclusive choices. 〃 In the selection 3A, The ACK/NACK for DL data transmission is transmitted with the CQI bit on the pre-defined UL CQICH. This option saves pilot overhead compared to selecting 3c. Since UL CQICH is always available, there is no necessary The UL ACKCH is allocated separately. However, the predefined UL CQICH must be configured large enough to transmit ACK/NACK information. When no ACK/NACK is transmitted, resources will be wasted. In the selection 3B, CQI information and ACK/ The NACK is transmitted on the UL ACKCH. The UL ACKCH can be located on any resource block configured by the Node B, and even multiplexed in the resource block for the UL data transmission of other UEs. Compared to the choice of 3C, the choice of 3B saves the pilot opening M314881 pin. If the DL shared control channel (DL-SCCH) is not decoded correctly, ACK/NACK will not be transmitted (because the UE does not know if there is a DL data transmission in the previous subframe). In this case, the Node B considers that the CQI bit is transmitted on the predefined UL ACKCH along with the ACK/NACK. However, ACK/NACK is not transmitted, and this will cause a problem. However, since the ACKCH is not always available, a predefined UL CQICH still needs to be allocated. Unless the Node B allocates other UEs to transmit on these resources, the resources of the predefined UL CQICH will be wasted, and this allocation will make the scheduling of the Node B more complicated. Alternatively, the Node B may allocate resources of the predefined UL CQICH to other UEs for transmission. In the selection 3C, ACK/NACK and CQI are transmitted separately. That is, the ACK/NACK is transmitted on the UL ACKCH, and the CQI bit is transmitted on the predefined UL CQICH. For option 3c, no resources are wasted on the UL CQICH; however, the pilot overhead will be more than the choice of 3 in and 3B. If there is UL data transmitted to the UE in the destination subframe (step 310), then example 4 is applied (step 314). In Example 4, there are four mutually exclusive choices for multiplexing. In option 4, the ack/Nack and cqi bits are transmitted together in the resource block scheduled for the UL share of the same_UE: data transmission. In this way, the ACK/NACK and CQI bits are compared with the UL data related control bits and user data of the same UE: Selecting 4A has no pilot overhead; however, the UE's UL # material rate will decrease. Since the UL shared data transmission is not always fine, it is still necessary to allocate a pre-defined 15 (M314881 first defined ULCQICH (and possibly UL ACKCH). Unless the Node B allocates other UEs to transmit on these resources, the pre-defined UL The resources of the CQICH (and ULACKCH, if any) will be wasted, and this allocation will make the scheduling of the Node B more complicated. Alternatively, the Node B can allocate resources of the predefined ULCQICH (and ULACKCH, if any). For other UEs, for transmission. In Option 4B, the ACK/NACK for DL data transmission is transmitted with the CQI bit on the predefined UL CQICH. Selecting 4B has fewer pilots than selecting 4D. Overhead, but selecting 4B has more pilot overhead than selecting 4A. Since ul CQICH is always available, there is no need to allocate UL ACKCH here, and the UE's UL data rate will not decrease. The pre-defined ul CQICH must be configured large enough to transmit ACK/NACK information. When no ACK/NACK is transmitted, resources are wasted. In Select 4C, CQI information is along with ACK/NACK information. The first defined UL ACKCH is transmitted. Compared with selecting 4D, selecting 4C has lower overhead, but selecting 4C has higher pilot overhead than selecting 4A. The UE's UL data rate will not be reduced. The other defects of 4C are the same as those of Option 3B in Example 3. In Select 4D, ACK/NACK and CQI are transmitted separately. That is, ACK/NACK is transmitted on a predefined UL ACKCH, and The CQI bit is transmitted on the predefined ULCQICH. For selecting 4D, no resources are wasted on the UL CQICH and UL ACKCH. The UL data of the UE will not be reduced. However, compared with the selection of 4A, 4B and 4C, M314881 selects 4D to have higher pilot overhead. In addition, the 'UL resource request (called "scheduled information,") bit can be transmitted on the same-UE UL CQICH or UL ACKCH, or in the same-UE The UL shared data transmission is transmitted together in the resource blocks scheduled. Accordingly, the UL CQICH or UL ACKCH needs to be configured large enough to be compatible with the UL resource request bit.

If the CQI bit is configured to be transmitted in the current subframe, then the example ^ is applied (step 408). In Example 1, the CQI bit is transmitted on a predefined ULCQICH. If the CQ:[bit is configured to be transmitted in the current subframe (step 406), the data unrelated control will not be transmitted 410) 〇 If there is UL data transmitted to the UE in the current subframe ( Step ^) 'determines whether the CQI bit is configured to be carried in the current subframe (step 412). If the CQI element is configured to be transmitted in the current subframe 17 M314881, then Example 2 is applied (step 414). In Example 2, two mutually exclusive choices for multiplexing are available. In option 2A, (: (^1 bit is transmitted on a predefined UL CQICH. Selecting 2A does not waste resources on UL CqICH; however, it requires more pilot overhead than selecting 2B. In 2B, the CQI bit is transmitted in the resource block scheduled for the UL shared data transmission of the same UE. In this way, the CQI bit is multiplexed with the UL data related control bit of the same UE and the user data. Selecting 2B has less pilot overhead than selecting 2A. However, the UL data rate of the UE will be reduced. Since UL shared data transmission does not always exist, a predefined ULCqICH still needs to be allocated. deB allocates other UEs to transmit on these resources, otherwise the negative source of the predefined UL CQICH will be wasted, and the allocation will make the schedule of N〇de B more complicated. Optionally, 'Node B can be pre- The defined ul CQICH: resources are allocated to other UEs for transmission. If the CQI bit is not configured to be transmitted in the current subframe (step 412), no data-independent control signaling will be transmitted (steps) 41〇). If in the previous If there is DL data transmitted to the UE in the frame (step 402), it is determined whether the UL data is transmitted to the UE in the current subframe (step 416). If no UL data is transmitted to the UE in the current subframe, Determining whether the CQI bit is configured to be transmitted in the current subframe (step 418). If the CQI bit is not configured to be transmitted in the current subframe, then Example 3 is applied (step 420). The ACK/NACK for DL data transmission shall be transmitted on the UL ACKCH. If the CQI bit is configured to be transmitted in the current subframe (step M314881 418), then Example 4 is applied (step 422). In 4, there is a triple exclusive selection for multiplexing. In option 4A, the ACK/NACK for dl data transmission is transmitted along with the CQI bit on a predefined UL. The selection 4A has a very low pilot overhead. However, the predefined UL CQICH must be configured large enough to transmit ack/NACK information. Resources will be wasted when ACK/NACK is not transmitted. UL LQICH is not always available when ACK/NACK needs to be transmitted. Therefore, it is still necessary to allocate a predefined UL·ACKCH at this time. Unless the NodeB allocates other UEs for uplink transmission on these resources, the resources of the predefined UL ACKCH will be wasted, and the allocation will make the scheduling of the Node B more complicated. Alternatively, the Node B may have a predefined UL. The CQICH (and UL ACKCH, if any) resources are allocated for transmission to other UEs. In Option 4B, CQI information is transmitted along with the ACK/NACK on a predefined UL ACKCH. Selecting 4B has a very low pilot overhead. If there is no positive read decoding DL-SCCH, then ACK/NACK will not be transmitted (because the UE does not know that there is a dl data transmission in the previous subframe). In this case, the Node B considers the CQI bit to be transmitted on the predefined UL ACKCH along with the AKC/NACK. However, ACK/NACK is not transmitted, and this will cause a problem. Since the ACKCH is not always available, a predefined UL CQICH still needs to be allocated. Unless the Node B allocates other UEs to transmit on these resources, the resources of the predefined UL CQICH will be wasted, and the allocation will make the scheduling of N〇de B more complicated. Alternatively, the Node B may allocate resources of a predefined UL CQICH to other UEs for transmission. M314881 In Select 4C, ACK/NACK and CQI are transmitted separately. That is, the ACK/NACK is transmitted on a predefined UL VIII (^::11, and the CQI bit is transmitted on a predefined ULCQICH. For the selection 4C, on the UL C (JICH or UL ACKCH) No resources are wasted; however, the selection of 4C has a higher pilot overhead than selecting 4A and 4B. If there is UL data transmitted to the UE in the current subframe (step 416), it is determined whether or not 〇:( The 31-bit is configured to be transmitted in the current subframe (step 424). If the CQI bit is configured to be transmitted in the current subframe, then Example 5 is applied (step 426). In Example 5, there is In multiplex 5, the ACK/NACK and CQI bits are transmitted in the resource block scheduled for the DL·shared data transmission of the same UE. In this way, ACK/NACK and The CQI bit is multiplexed with the UL data related control bits of the same UE and the user data. Compared with selecting 5B, 5C and 5D, the selection 5A has a smaller pilot overhead, but the UE's UL data rate will be reduced. Since UL·shared data transmission does not always exist, it is still necessary to allocate a predefined UL. CQICH (and possibly ULACKCH). Unless the Node B allocates other UEs to transmit on these resources, the resources of the predefined ULCQICH (and ACKCH, if any) will be wasted, and this allocation will make the Node B schedule more Complex. Alternatively, the Node B may allocate resources of a predefined ULCQICH (and ULACKCH, if any) to other UEs for transmission. In Option 5B, ACK/NACK and CQI bits for DL data transmission Together, transmitted on a predefined UL CQICH. Compared to selecting 5D phase 20 M314881, selecting 5B has lower pilot overhead. The UE's UL data rate will not be reduced. However, the predefined UL CQICH must be configured enough. Large to transmit ACK/NACK information. When no ACK/NACK is transmitted on the UL CQICH, resources will be wasted. Since UL CQICH is not always available when ACK/NACK needs to be transmitted, UL ACKCH still needs to be allocated. Unless the NodeB allocates other UEs to transmit on these resources, the resources of the predefined UL ACKCH will be wasted, and the allocation will make the scheduling of the Node B more complicated. Alternatively, the Node B can pre- The resources of the first defined UL ACKCH are allocated to other UEs for transmission. In the selection 5C, CQI information is transmitted on the UL ACKCH together with ACK/NACK. Compared with selecting 5D, selecting 5C saves pilot overhead. The UL data rate of the UE will not decrease. However, selecting 5C has more pilot overhead than selecting 5A. Furthermore, the other disadvantages of selecting 5c are the same as the disadvantage of selecting 4B in Example 4.
在選擇5D中,ACK/NACK以及CQI是分開傳送的。 也就是說,ACK/NACK在預先定義的UL ACKCH上傳送, 而CQI位元則在預先定義的ULCQICH上傳送。對選擇5DIn selecting 5D, ACK/NACK and CQI are transmitted separately. That is, the ACK/NACK is transmitted on a predefined UL ACKCH, and the CQI bit is transmitted on a predefined ULCQICH. For choosing 5D
來說,在UL CQICH和UL ACKCH上並未浪費資源。UE 的UL資料速率將不會降低。但是與選擇5A、5b以及5C 相比’選擇5D具有較多的導頻開銷。 如果沒有將CQI位元配置成待在目前副訊框中傳送(步 驟424),則應用範例6 (步驟428)。在範例6中,有用 於多工的兩互斥選擇。 21 M314881 在選擇6A中,ACK/NACK資訊係在爲同一 UE的ul 共用資料傳輸所排程的資源區塊内傳送。這樣一來, ACK/NACK資訊與同一 UE的UL資料相關控制資訊以及 用戶資料進行多工。選擇6A沒有導頻開銷;但是UE的 UL資料速率將會降低。由於UL共用資料傳輸並非總存在 的,因此仍需分配UL ACKCH。除非NodeB分配其他UE 在這些資源上傳送,否則預先定義的UL ACKCH的資源將 被浪費,而該分配會使Node B的排程更爲複雜。可選擇 地,Node B可以將預先定義的UL ACKCH資源分配給其 他UE,以進行傳輸。 在選擇6B中,ACK/NACK在UL ACKCH上傳送的。 對選擇6B來說,UE的UL資料速率將不會降低。UL ACKCH的資源也不會浪費;但是與選擇6A相比,選擇6B 具有更多的導頻開銷。 此外,UL·資源凊求(稱爲“排程資訊”)位元可以在 同一 UE的ULCQICH或UL ACKCH上傳送,或者也可以 在爲同一 UE的UL共用資料傳輸所排程的資源區塊内一起 傳送。相應地,ULCQICH或UL ACKCH需要被配置得足 夠大,以與UL資源請求位元相適應。或者,在爲同一 ue 的UL共用資料傳輸所排程的資源區塊中需要保留ul資源 請求位元的數量。 系統結構 第5圖是用於排程和多工CQI報告以及ACK/NACK報 告的系統500的方塊圖,其中包括UE 502和Node B 504。 22 M314881 UE 502包括處理器510、與處理器510進行通信的發射器/ 接收器512以及與發射器/接收器512相連的天線514。多 工器516與處理器510進行通信。反饋產生器518與處理 器510以及多工器516進行通信。該反饋產生器518可以 爲接收到的DL資料提供CQI以及ACK/NACK。In terms of resources, no resources are wasted on UL CQICH and UL ACKCH. The UL data rate of the UE will not decrease. However, selecting 5D has more pilot overhead than selecting 5A, 5b, and 5C. If the CQI bit is not configured to be transmitted in the current subframe (step 424), then Example 6 is applied (step 428). In Example 6, two mutually exclusive choices are available for multiplexing. 21 M314881 In option 6A, the ACK/NACK information is transmitted in the resource block scheduled for the same UE's ul shared data transmission. In this way, the ACK/NACK information is multiplexed with the UL data related control information and the user data of the same UE. Selecting 6A has no pilot overhead; however, the UE's UL data rate will be reduced. Since UL shared data transmission does not always exist, UL ACKCH still needs to be allocated. Unless the NodeB allocates other UEs to transmit on these resources, the resources of the predefined UL ACKCH will be wasted, and the allocation will make the scheduling of the Node B more complicated. Alternatively, the Node B may allocate a predefined UL ACKCH resource to other UEs for transmission. In option 6B, ACK/NACK is transmitted on the UL ACKCH. For the selection of 6B, the UL data rate of the UE will not decrease. The resources of the UL ACKCH are also not wasted; however, the selection of 6B has more pilot overhead than the selection of 6A. In addition, the UL resource request (referred to as "scheduling information") bit may be transmitted on the ULCQICH or UL ACKCH of the same UE, or may also be in the resource block scheduled for the UL shared data transmission of the same UE. Transfer together. Accordingly, the ULCQICH or UL ACKCH needs to be configured to be large enough to accommodate the UL resource request bits. Alternatively, the number of ul resource request bits needs to be reserved in the resource block scheduled for the UL shared data transmission of the same ue.
