UTRA、E-UTRA、UMTS、LTE、LTE-A 和 GSM。在來自 名為「第三代合作夥伴計劃2」（3GPP2 )的組織的文件中 描述了 cdma2000和UMB。本文述及之技術可以用於上文 所提到的無線網路和無線電技術以及其他無線網路和無 線電技術》為了清晰起見，下文針對LTE來描述技術的某 些態樣，並且在以下的描述中多數使用LTE術語。 圖1圖示無線通訊網路100，在無線通訊網路100中可 以執行本文述及之RA程序。網路100可以是LTE網路或 者某種其他無線網路。無線網路1 00可以包含多個進化型 節點B ( eNBs) 110以及其他網路實體。eNB是與UE進 201246880 行通訊的實體並且亦可以被稱為基地台、_點b和存取點 等。每個eNB可以為特定的地理區域提供通訊覆蓋。在 3GPP中’取決於在其中使用術肖「細胞服務區」的上下 文，該術語可以代表eNB的覆蓋區域及/或服務於該覆蓋 區域的eNB子系統。 eNB可以為巨集細胞服務區、微微細胞服務區、毫微微 細胞服務區及/或其他類型的細胞服務區提供通訊覆蓋。巨 集細胞服務區可以覆蓋相對較大的地理區域（例如，半徑 為數公里的地理區域）並且可以允許由具有訂閱服務的ue 進行無限制的存取。微微細胞服務區可以覆蓋相對較小的 地理區域並且可以允許由具有訂閱服務的UE進行無限制 的存取。毫微微細胞服務區可以覆蓋相對較小的地理區域 (例如’家庭）並且可以允許由與毫微微細胞服務區相關 聯的UE (例如，封閉用戶群組（CSG)中的UE)進行受 限制的存取。巨集細胞服務區的eNB可以被稱為巨集 eNB。微微細胞服務區的6ΝΒ可以被稱為微微eNB »毫微 微細胞服務區的eNB可以被稱為毫微微eNB或家庭eNB (HeNB )。在圖1所圖示的實例中，εΝΒ 11 0a可以是用於 巨集細胞服務區102a的巨集eNB，eNB 110b可以是用於 微微細胞服務區102b的微微eNB，而eNB 110c可以是用 於毫微微細胞服務區l〇2c的毫微微eNB» eNB可以支援一 個或多個（例如，3個）細胞服務區。術語「eNB」、「基 地台」和「細胞服務區」可以互換使用。 無線網路100亦可以包含中繼站。中繼站是能夠從上游 201246880 (例如’ eNB & UE)接收f料傳輸並且將資料傳輸發 =下游站（例如’ UE或_)的實體。中繼站亦可以 疋此夠中繼針對其他UE的傳輸的UE。在圖}所圖示的實 例中，為了促進eNB 11〇a和UE 12〇d之間的通訊，中繼 站il〇d可以與巨集eNB u〇a和UE i2〇d進行通訊。中繼 站亦可以被稱為中繼eNB、中繼基地台和中繼站等。 無線網路1〇〇可以是包含不同類型的eNB (例如，巨集 eNB、微微eNB、毫微微eNB以及中繼eNB等）的異質網 路。該等不同類型的eNB可能具有不同的發射功率位準、 不同的覆蓋區域並且對無線網路1〇〇中的干擾有不同的影 響。舉例而言，巨集eNB可能具有高發射功率位準（例如， 5-40瓦特），而微微eNB、毫微微eNB以及中繼eNB可能 具有較低的發射功率位準（例如，〇 J _2瓦特）。 網路控制器130可以耦合到一組eNB並且為該等eNB 提供協調和控制。網路控制器130可以經由回載來與eNB 進行通訊。舉例而言，eNB相互之間亦可以經由無線回載 或有線回載來直接地或間接地進行通訊。 如下文所更為詳細地描述的’根據某些態樣，eNB可以 執行細胞服務區間干擾協調（ICIC>ICIC可能涉及在eNB 之間進行協商以實現資源協調/劃分，從而將資源分配給位 於強干擾eNB附近的eNB。可能除了 CRS以外，干擾eNB 可以避免在所分配的/受保護的資源上進行發送。隨後，在 存在干擾eNB的情況下，UE能夠在受保護的資源上與 進行通訊，並且可能意識不到來自干擾eNB的干擾（可能 201246880 除了 CRS之外）。 % UE 120可以遍佈於整個無線網路1〇〇，並且每個ue皆 可以是靜止的或是行動的。UE亦可以被稱為終端、行動 站、用戶單元以及站等。UE可以是蜂巢式電話、個人數 位助理（PDA)、無線數據機、無線通訊設備、手持設備、 膝上型電腦、無線電話、無線區域迴路（Wll )站、智慧 型電話、小筆電以及智慧型電腦等。 圖2圖示基地台/eNB 210和接收系統22〇(例如，ue或 者中繼節點）的設計方塊圖，其可以是圖丨中的基地台 中的一個和UE中的一個。基地台21〇可以配備有τ個天 線234a-234t，並且接收系統22〇可以配備有r個天線 252a-252r，其中通常情況下，τη並且ru。 在基地台21〇處，發射處理器213可以從資料源212接 收用於一或多個UE的資料，基於從UE接收的仰來選 擇針對每個UE的一或多個調制和編碼方案（Mcs)，基於 為每個UE選擇的MCS來處理（例如，編碼和調制）針對 該UE的資料，並且向所有UE提供資料符號。發射處理 器213亦可以處理系統資訊（例如，針對SRpi等）和控 資訊（例如’ CQI請求、容許和上層訊號傳遞等）並且 提供管理負擔符號和控制符號。處理器213亦可以産生參 • 考信號（例如，CRs)和同步信號（例如，Pss和sss) .的參考符號。若可行，發射（τχ)多輸入多輪出（MIM〇) 處理器230可以對資料符號、控制符號、管理負擔符號及 /或參考符號執行空間處理（例如，預編碼），並且可以向 201246880 τ個調制器（M0Ds) 23 每個調制器-可以對各別輸=

子訊框中的2L個符號週期。 在LTE中’針對eNB支援的每個細胞服務區，eNB可以 在下行鏈路上在系統頻寬中央的1.〇8 mhz中發送主要同 步信號（PSS)和次要同步信號（sss)。如圖3所示，可 以在具有標準循環字首的每個無線電訊框的子訊框〇和5 中的符號週期6和5中分別發送pss和SSS。PSS和SSS 可以由UE使用以用於進行細胞服務區搜尋和獲取。針對 eNB支援的每個細胞服務區，eNB可以跨越系統頻寬來發 送特定於細胞服務區的參考信號（CRS)。可以在每個子訊 框的某些符號週期中發送CRS，並且CRS可以由ue使用 以執行通道估計、通道品質量測及/或其他功能。eNB亦可 以在某些無線電訊框的時槽i中的符號週期〇_3中發送實 體廣播通道（PBCH>PBCH可以攜帶某些系統資訊1仙 可以在某些子訊框中在實體下行鏈路共享通道（pdsch) 上發送諸如系統資訊區塊（SIBS)之類的其他系統資訊。 eNB可以在子訊框的前B個符號週期内在實體下行鏈路控 制通道（PDCCH)上發送控制資訊/資料，其中對於每個子 訊框而言，B是可配置的。eNB可以在每個子訊框的剩餘 符號週期内在PDSCH上發送訊務資料及/或其他資料。 如上所述，無線通訊系統可以包括與施主基地台相關聯 的中繼節點以向使用者裝備（UEs)提供服務。如上所述， 中繼節點可以經由施主基地台連接到無線電存取網路。藉 13 201246880 由向複數個UE提供經由施主基地台進行的服務，中繼節 點可以用於對給定地理區域中的覆蓋進行補充和擴展。 圖4圖示可以在其中實踐本案的某些態樣的示例性無線 系統400。如圖所示，系統4〇〇包含施主基地台402 (亦 被稱為施主細胞服務區、施主存取點（AP )、施主BS、施 主e節點B或者DeNB )，該施主基地台402經由中繼節點 406 (亦被稱為中繼存取點、中繼基地台或者ReNB )與 UE 404進行通訊。中繼節點4〇6可以經由回載鏈路408與 施主BS 402進行通訊’並且經由存取鏈路41〇與ue 404 進行通訊。換言之，中繼節點406可以在回載鏈路408上 從施主BS 402接收下行鏈路訊息，並且在存取鏈路41〇 上將該等訊息中繼到UE 404。類似地，中繼節點406可以 在存取鏈路410上從UE 404接收上行鏈路訊息，並且在 回载鏈路408上將該等訊息中繼到施主bs 402。 根據某些態樣，回載鏈路408可以是「帶内（inband)」 連接，其中網路至中繼站的鏈路（諸如，回載鏈路4〇8) 與由施主基地台定義的施主細胞服務區内的網路至UE的 直接鏈路共孕相同的頻帶。在此種情況下，與LTE版本8 相容的UE能夠連接到施主。根據某些態樣，回載鏈路可 以是「帶外（outband )」連接，其中網路至中繼站的鏈路 可以不與施主細胞服務區内的至UE的直接鏈路操作在相 同的頻帶内。 根據某些態樣，中繼節點406可以是與高級LTE相容的 「類型1」中繼節點。類型i中繼節點是帶内中繼節點， 201246880 通吊’類型1中繼節點具有以下特性：類型【中繼節點對 細胞服務區進行控制，每個細胞服務區對ue而言好像是 與施主細胞服務區不同的獨立細胞服務區。該等細胞服務 區可以具有其自己的實體細胞服務區ID (如LTE版本8 中所定義的），並且中繼節點可以發送其自己的同步通 道、參考符號以及其他控制資訊。在單細胞服務區操作的 清況下，UE可以直接從中繼節點接收排程資訊和混合自 動重傳請求（HARQ)反饋，並且UE可以將其控刺通道（例 如’ SR、吻和ACK)發送到中繼節點。對於版本8仙 而言，類型1中繼節點可能看起來好像是版本8 e節點B (亦即’類型1中繼節點可以是反向相容的）。對於與高 級LTE相容的UE而言，類型i中繼節點可能看起來不同 於版本8 ^點B以賦能或允許進一步的效能增強。 伙根據某些態樣，針對帶内中繼，回載鍵路彻（亦即，e 即點B至中繼站的鏈路）可以與存取鍵路4i〇 (亦即，中 繼站至UE的鏈路）操作在相同的頻率上。由於中繼站的

Description of the invention: [Technical field to which the invention pertains] In general, some aspects of the present invention relate to wireless communication systems, and more specifically to confirmation of transmissions transmitted across multiple subframes. Technology. [Prior Art] Wireless communication systems are widely deployed to provide various types of communication contents such as voice, material, and the like. Such systems may be multiplexed access systems capable of supporting communication with multiple users by sharing available system resources (eg, bandwidth, transmit power). Examples of such multiplex access systems include a code division multiplex access (CDMA) system, a time division multiplex access (TDMa) system, a frequency division multiplex access (FDMA) system, and a 3Gpp long term evolution (LTE) system. And an orthogonal frequency division multiplexing access (OFDMA) system. In general, a wireless multiplex access communication system can simultaneously support communication for multiple wireless terminals. Each terminal communicates with one or more base stations via transmissions on the forward and reverse links. The forward link (or downlink) represents the communication link from the base station to the terminal, and the reverse link (or uplink) represents the communication link from the terminal to the base station. This communication link can be established via a single-input single-output (SIS0), multiple-input single-output (MISO), or multiple-input multiple-output (ΜΙΜΟ) system. To complement the conventional mobile phone network base station, additional base stations can be deployed to provide more robust wireless coverage to the mobile unit. For example, a wireless relay station and a small coverage base station can be deployed (eg 201246880 such as 'often referred to as an access point base station, home node B, femto access point, or femtocell service area) for incremental Increased capacity, richer user experience and indoor coverage. Often, such small coverage base stations are connected to the Internet and mobile service provider networks via DSL routers or cable modems. Since it is possible to add these other types of bases to a known mobile phone network (eg, back-loading) in a different way than conventional base stations (eg, 'macro base stations'), a need for management is required. Effective techniques for these other types of base stations and their associated user equipment.

The techniques described herein can be used in a variety of wireless communication networks such as CDMA, TDMA, FDMA '〇FDMA, SC-FDMA, and other networks. The terms "network" and "system" are often used interchangeably. The Cdma 201246880 network can implement radio technologies such as Universal Terrestrial Radio Access (UTRA), cdma2000, etc. UTRA includes Broadband CDMA (WCDMA), Time Division Synchronous CDMA (TD-SCDMA), and other variants of CDMA. Cdma2000 covers IS-2000, IS-95, and IS-856 standards. A TDMA network can implement a radio technology such as the Global System for Mobile Communications (GSM). The OFDMA network can implement radio technologies such as evolved UTRA (E-UTRA), Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi), IEEE 802.16 (WiMAX), IEEE 802.20, Flash-OFDM, and the like. UTRA and E-UTRA are part of the Universal Mobile Telecommunications System (UMTS). Frequency Division Duplex (FDD) and Time Division Duplex (TDD) 3GPP Long Term Evolution (LTE) and LTE-Advanced (LTE-A) are new releases of UMTS that use E-UTRA, which employs OFDMA on the downlink. SC-FDMA is used on the uplink. UTRA, E-UTRA, UMTS, LTE, LTE-A, and GSM are described in documents from an organization named "3rd Generation Partnership Project" (3GPP). Cdma2000 and UMB are described in documents from an organization named "3rd Generation Partnership Project 2" (3GPP2). The techniques described herein may be used in the wireless networks and radio technologies mentioned above, as well as other wireless networks and radio technologies. For clarity, certain aspects of the techniques are described below for LTE, and in the following Most of the descriptions use LTE terminology. 1 illustrates a wireless communication network 100 in which the RA procedures described herein can be performed. Network 100 can be an LTE network or some other wireless network. Wireless network 100 can include multiple evolved Node Bs (eNBs) 110 and other network entities. The eNB is an entity that communicates with the UE into 201246880 and may also be referred to as a base station, _point b, and access point. Each eNB can provide communication coverage for a particular geographic area. In 3GPP, depending on the context in which the syllabic "cell service area" is used, the term may refer to the coverage area of the eNB and/or the eNB subsystem serving the coverage area. The eNB may provide communication coverage for macrocell service areas, pico cell service areas, femtocell service areas, and/or other types of cell service areas. The macro cell service area can cover a relatively large geographic area (e.g., a geographic area with a radius of several kilometers) and can allow unrestricted access by a ue with a subscription service. The picocell service area can cover a relatively small geographic area and can allow unrestricted access by UEs with subscription services. The femtocell service area may cover a relatively small geographic area (eg, 'family') and may allow restricted access by UEs associated with the femtocell service area (eg, UEs in a Closed Subscriber Group (CSG)) access. The eNB of the macro cell service area may be referred to as a macro eNB. An eNB of a picocellular service area, which may be referred to as a pico eNB » femtocell service area, may be referred to as a femto eNB or a home eNB (HeNB). In the example illustrated in FIG. 1, εΝΒ110a may be a macro eNB for macrocell service area 102a, eNB 110b may be a pico eNB for picocell service area 102b, and eNB 110c may be for The femto eNB» eNB of the femtocell service area 102c can support one or more (eg, 3) cell service areas. The terms "eNB", "base station" and "cell service area" are used interchangeably. Wireless network 100 can also include a relay station. A relay station is an entity capable of receiving f-material transmissions from upstream 201246880 (e.g., 'eNB & UE) and transmitting data to downstream stations (e.g., 'UE or _). The relay station may also be able to relay UEs for transmissions to other UEs. In the example illustrated in Fig.}, in order to facilitate communication between the eNB 11〇a and the UE 12〇d, the relay station il〇d can communicate with the macro eNB u〇a and the UE i2〇d. A relay station may also be referred to as a relay eNB, a relay base station, a relay station, and the like. The wireless network may be a heterogeneous network containing different types of eNBs (e.g., macro eNBs, pico eNBs, femto eNBs, and relay eNBs, etc.). These different types of eNBs may have different transmit power levels, different coverage areas, and have different effects on interference in the wireless network. For example, a macro eNB may have a high transmit power level (eg, 5-40 watts), while a pico eNB, a femto eNB, and a relay eNB may have lower transmit power levels (eg, 〇J _2 watts) ). Network controller 130 can be coupled to a group of eNBs and provide coordination and control for the eNBs. Network controller 130 can communicate with the eNB via a backhaul. For example, the eNBs can also communicate directly or indirectly via wireless backhaul or wired backhaul. As described in more detail below, 'according to certain aspects, an eNB may perform cell service interval interference coordination (ICIC> ICIC may involve negotiating between eNBs to achieve resource coordination/division, thereby allocating resources to being located strong Interfering with eNBs in the vicinity of the eNB. It is possible that interfering eNBs may avoid transmitting on the allocated/protected resources in addition to the CRS. Subsequently, in the presence of interfering eNBs, the UE can communicate with the protected resources, And may not be aware of interference from interfering eNBs (possibly 201246880 in addition to CRS). % UE 120 may be spread throughout the wireless network, and each ue may be stationary or mobile. UE may also Known as terminals, mobile stations, subscriber units, stations, etc. The UE can be a cellular phone, a personal digital assistant (PDA), a wireless data modem, a wireless communication device, a handheld device, a laptop, a wireless telephone, a wireless regional loop. (Wll) station, smart phone, small notebook, smart computer, etc. Figure 2 illustrates base station/eNB 210 and receiving system 22 (e.g., ue Design block diagram of the relay node), which may be one of the base stations in the picture and one of the UEs. The base station 21A may be equipped with τ antennas 234a-234t, and the receiving system 22〇 may be equipped with r Antennas 252a-252r, where τη and ru are normally. At the base station 21〇, the transmit processor 213 can receive data for the one or more UEs from the data source 212 based on the preferences received from the UE. For one or more modulation and coding schemes (Mcs) for each UE, the data for the UE is processed (eg, encoded and modulated) based on the MCS selected for each UE, and the data symbols are provided to all UEs. The device 213 can also process system information (eg, for SRpi, etc.) and control information (eg, 'CQI request, allow and upper layer signal delivery, etc.) and provide management burden symbols and control symbols. The processor 213 can also generate a reference signal ( For example, CRs) and reference symbols for synchronization signals (eg, Pss and sss). If feasible, transmit (τχ) multiple input multiple rounds (MIM〇) processor 230 can be used for data symbols, control symbols The management bearer symbol and/or the reference symbol performs spatial processing (eg, precoding), and can be processed to 201246880 τ modulators (M0Ds) 23 each modulator - can be processed for each input = stream, OFDM, etc.) To: 'such as 'for the can sample stream.

Each demodulator 254 can condition (e.g., chop, amplify, downconvert, and digitize) the received signal to obtain an input. Sampling. Each demodulator 254 can further process the input samples (e.g., for defamation, etc.) to obtain received symbols. The mask detector 256 can obtain received symbols from all r decimations and evaluate the receivers.贞 ( (if available) and provide the detected symbols. The receiving processor... can process the detected symbols (eg, 'demodulation and decoding), provide decoded data for the receiving system 220 to the data slot and The decode control information and system information are provided to the controller/processor 28. As described below, the channel processor 284 can determine RSRp, RSSI, rsrq, kiss, etc. On the uplink, the transmit processor at the receive system 22 The data from the data source, 262 and control information from the controller/processor 280 can be received and processed (e.g., for reports including RSRp, rssi, r, and CQI, etc.). The processor 264 can also generate a Reference symbols of the plurality of 201246880 reference signals. The symbols from the transmit processor 264 may be precoded by the processor 266 (if applicable), further processed by the modulators 254a-254r (e.g., for SC_FDM, 〇FDM, etc.) and Sended to the base 210. At the base station 21, uplink signals from the receiving system 22A and other UEs can be received by the antenna 234, processed by the demodulator 232, and detected by the MIMCM|detector 236 (if feasible) And further processed by the receive processor 238 to obtain decoded data transmitted by the receiving system 22 and decoded control information. The processor 238 may The decoded poor material is provided to the data slot 239' and the decoded control information is provided to the controller/processor 240. The controller/processor 240 and the processor can respectively conduct operations at the base station 21 and the receiving system 220, respectively. The processor 24's and/or other processors and modules at the base station 2iq may perform or direct operations for configuring the receiver system 22G in various ways. The memory banks (10) and 282 may store the base station 210 and The data and code of the receiving system 22 are received. The scheduling ^44 can be transferred to the next (four) way and/or the uplink material. Figure 3 illustrates an exemplary frame structure of 卿 in LTE. Each = line key and uplink key (four) input isochronous line can be divided into radio frame units. Each of the benefits of the thunder stomach &,,, wire can have a predetermined duration (such as '10 milliseconds (ms)) and Bei Yu (specially quoted ".," m 乂 broken into 1 〇 Frame (index is 0-9). Each sub-frame can be "" J 乂 contains two time slots. Therefore, each ..., the line teleframe can contain 2 时 slots, and the number of people τ can be 0-19). Each time slot is included to contain L symbol periods, for example, for standard cycle prefixes, 12 201246880 contains 7 symbol periods (as shown in Figure 2) or for extended cycle prefixes, and Lu contains 6 symbol periods. The index 〇 to 2L_] can be assigned to 2L symbol periods in each subframe. In LTE, for each cell service area supported by the eNB, the eNB may transmit a primary synchronization signal (PSS) and a secondary synchronization signal (sss) in the downlink at 1. 〇8 mhz in the center of the system bandwidth. As shown in Figure 3, pss and SSS can be transmitted in symbol periods 6 and 5, respectively, in subframes 〇 and 5 of each radio frame having a standard cyclic prefix. PSS and SSS can be used by the UE for cell service area search and retrieval. For each cell service area supported by the eNB, the eNB may transmit a cell service area specific reference signal (CRS) across the system bandwidth. The CRS can be sent in certain symbol periods of each sub-frame, and the CRS can be used by ue to perform channel estimation, channel quality measurements, and/or other functions. The eNB may also send a physical broadcast channel in the symbol period 〇_3 in the time slot i of some radio frames (PBCH> PBCH may carry some system information 1 sen may be in the physical downlink in some subframes Other system information such as System Information Block (SIBS) is transmitted on the shared channel (pdsch). The eNB may send control information/data on the Physical Downlink Control Channel (PDCCH) in the first B symbol periods of the subframe. For each subframe, B is configurable. The eNB may send traffic data and/or other data on the PDSCH during the remaining symbol period of each subframe. As described above, the wireless communication system may include The relay base node associated with the donor base station provides services to the user equipment (UEs). As described above, the relay node can be connected to the radio access network via the donor base station. By 13 201246880 by providing to a plurality of UEs via The service carried out by the donor base station, the relay node can be used to supplement and extend the coverage in a given geographic area. Figure 4 illustrates certain states in which the present case can be practiced. Exemplary wireless system 400. As shown, system 4 includes a donor base station 402 (also referred to as a donor cell service area, a donor access point (AP), a donor BS, a donor eNodeB, or a DeNB) The donor base station 402 communicates with the UE 404 via a relay node 406 (also referred to as a relay access point, relay base station, or ReNB). The relay node 4〇6 can communicate with the donor via the backhaul link 408. The BS 402 communicates 'and communicates with the ue 404 via the access link 41. In other words, the relay node 406 can receive downlink messages from the donor BS 402 on the backhaul link 408, and on the access link 41. The messages are relayed to the UE 404. Similarly, the relay node 406 can receive uplink messages from the UE 404 over the access link 410 and relay the messages on the backhaul link 408. To donor bs 402. According to some aspects, the backhaul link 408 can be an "inband" connection, where the network-to-relay link (such as the back-up link 4〇8) is associated with the donor base. Direct link co-pregnancy of the network to the UE in the donor cell service area defined by the station The same frequency band. In this case, UEs compatible with LTE Release 8 can connect to the donor. According to some aspects, the backhaul link can be an "outband" connection, where the network to the relay station The link may not operate in the same frequency band as the direct link to the UE within the donor cell service area. According to some aspects, the relay node 406 may be a "type 1" relay node that is compatible with LTE-Advanced. The type i relay node is an in-band relay node, and the 201246880 pass-through 'type 1 relay node has the following characteristics: type [relay node controls the cell service area, and each cell service area seems to be a donor to the ue Different cell service areas in different cell service areas. These cell service areas may have their own physical cell service area ID (as defined in LTE Release 8), and the relay node may send its own synchronization channel, reference symbols, and other control information. In the case of single cell service area operation, the UE can receive scheduling information and hybrid automatic repeat request (HARQ) feedback directly from the relay node, and the UE can send its control channel (eg 'SR, kiss and ACK) To the relay node. For version 8 cents, a Type 1 relay node may appear to be a version 8 eNodeB (i.e., a Type 1 relay node may be backward compatible). For UEs that are compatible with advanced LTE, Type i relay nodes may appear to be different from Release 8^Point B to enable or allow for further performance enhancements. According to some aspects, for in-band relay, the backhaul keyway (that is, e is the link from point B to the relay station) can be connected to the access key 4i (ie, the link of the relay station to the UE). ) operate on the same frequency. Due to the fact that the transmitter of the relay station may cause interference with the receiver of the relay station itself, it may not be feasible to transmit from the eNodeB to the relay station and the relay station to the same frequency resource on the same frequency resource. For example, the relay node may: it is difficult to receive 2 channels from the donor base station 402 during a conventional PDCCH period, because the relay node 4〇6 may have to send itself to the 4〇8^4 during this period. Reference signal. Therefore, in order to allow in-band reload of the relay traffic of the back-up link, some resources may be reserved for the back-up key, and the resources may not be used for the respective relays 15 201246880 = point , Mei's access link is thorough. According to some aspects, as described below, the secondary node 406 can be configured for half-duplex operation such that the control channel of the loadback switch 8 can be reserved for the base station 4〇2 to the relay node 406.

In other words, there is only one effect in the (four) candidate 'downlink back (four) way and the downlink access scale. Secondly, the 'up to 6 link 0 in the uplink backhaul link and the uplink link access chain is up. The relay station is also multiplexed on a single load and on the fly. In other words, only one of the uplink and uplink accesses is active at any time. Lower root = some aspects described herein, radio resources can be used to transmit two-loaded transmissions and uplink-backhaul transmissions. (4) In the middle, at the point, the boundary of the access link downlink sub-axis is aligned with the boundary of the downlink sub-frame, and a σ ^ ^ dry s 迠 adjustable adjustment allows the alignment: Transmit and/or receive to switch. According to some aspects, the downlink can be sent back to the sub-frame to return the carrier. It can also be "semi-static:: two (the downlink key set may occur during the uplink (the uplink shunt may occur in the middle), or the timing relationship is based on the downlink spoofing link back to the sub-frame set. Lights 16 201246880 Depending on certain aspects, a physical control channel (hereinafter referred to as a relay entity downlink control channel or "R_PDCCHj") may be used to dynamically or "semi-persistently" allocate resources within a semi-statically assigned subframe. Assigned to downlink backhaul data (corresponding to physical channels such as relay entity downlink shared channels or "R-PDSCH"). According to some aspects, r_pdcch may be assigned the same and / or - or more Downlink resources in subsequent subframes. According to some aspects, r_pdcch can also be used to dynamically or "semi-persistently" assign resources to uplink payload data (corresponding to uplinks such as relay entities). Link shared channel or physical channel such as "R_PUSCH". According to some aspects, the R_PDCCH may assign uplink key resources in one or more subsequent sub-frames. According to some aspects, in a semi-static manner Means Within the physical resource blocks (PRBs) transmitted to the R_PDCCH, a subset of the resources may be used for each R-PDCCH. The actual resource set for the R pDCCH transmission within the semi-statically assigned pR]B mentioned above may be The subframes are dynamically changed. The resources may correspond to a complete set of 〇FDM symbols available for the backhaul link or to a subset of the OFDM symbols. The semi-statically assigned PRBs mentioned above are not The resources for the R-PDCCH may be used to carry r_pdsch or PDSCH. According to some aspects, the R_PDCCH may be transmitted starting from an OFDM symbol within a sufficiently late subframe so that the relay station can receive the R-PDCCH. As described below, r_pdsch and R-PDCCH may be transmitted within the same pRB or within separate PRBs. According to some aspects, detailed R_pDCCH transmitter processing (ie, channel coding, interleaving, multiplexing, etc.) may Reuse LTe 17 201246880 Release 8 functionality to the extent possible 'however, by considering the characteristics of the relay node, 允许 to allow the shift to the necessary program or the program that occupies the bandwidth. According to some aspects, it can be performed according to LTE Release 8. Tune To get the "search space" method for reloading the keyway, the LTE version 8 utilizes a shared search space that can be semi-statically configured (and potentially potentially including the entire system bandwidth). Configuring a search node-specific search space (5), the search space is implicitly or explicitly learned by the relay node. The HARQ feedback for the successor system is based on the aspect, at the donor eNodeB to the relay node. The (reload) key or relay section _ UE (access) link, the dl subframe can be semi-statically configured independently of the UL subframe. The mapping can be specified, and the mapping is decided to carry for the corresponding! The UL subframe of the U]L ack/nack of the 1 subframe may further define the mapping to determine the DL subframe that carries the UL grant for the corresponding UL subframe. It is also possible to configure asymmetric mapping, that is, to configure more DL subframes than the number of UL subframes, or vice versa. In the case of an asymmetric configuration, for DL and UL backhaul subframes (ie, the backhaul link from the donor eNodeB to the RN or the subframe on the access key from the RN to the UE) It is possible (or even desirable) to configure a many-to-one relationship in which the DL subframes are more numerous than the UL subframes. In this case, UL HaRq feedback may be required to resolve multiple transmissions. Therefore, some aspects of the present case provide the relay node with the means for confirming in the single uplink backhaul transmission whether the downlink backhaul transmission transmitted from the donor base station on the plurality of subframes 201246880 is successfully received. Devices and technology. Although some examples herein are described with respect to a loadback connection between a donor base station and a relay node, the techniques provided herein can also be extended to access links. Alternatively, the UE can confirm in the single uplink transmission on the access link whether the downlink transmission sent from the relay node on the plurality of subframes has been successfully received. When the base station adopts a frequency division duplex (FDD) system, this is different from the case where the donor base station directly provides services to the UE. In the case where the donor base station directly provides services to the UE, the available downlink subframes are available. And the uplink subframes are the same in number. The mapping of the downlink subframe to the uplink subframe is one-to-one. As a result, the donor base station needs to handle different UL HARQ feedback from the relay node and from the UE directly served by the donor base station. FIG. 5 illustrates an exemplary wireless system 500 having elements capable of performing the operations described herein. As shown, the wireless system 5 includes a relay node 51A and a donor base station 520. Although not shown in the figure, the relay node 51A may allow the base station 520 to communicate with a plurality of UEs. According to some aspects, the donor base station 52 can include a message processing module 524' which is configured to generate control messages and profile messages that need to be sent to the successor node 5. As described above, the messages may carry information that needs to be forwarded by the relay node 51 to one or more UEs. As shown, the message processing module can generate one or more physical downlink shared channel (PDSCH) messages (labeled as relay PDSCH or "R_pDSCH") that need to be transmitted to the relay node via transmitter module 528. 201246880 In some cases, donor base station 520 can transmit multiple r_pdsch messages. The multiple R-PDSCH messages can be transmitted on multiple subframes using one or more component carriers. According to some aspects, the R-PDSCH message may carry data or control information that needs to be relayed to at least one UE. According to some aspects, the relay node may receive a plurality of physical downlink-key shared channel (PDSCH) transmissions or physical downlink control channel (PDCCH) transmissions that need to be relayed to at least one UE. According to one aspect, the relay node can receive uplink grant information that needs to be relayed to the UE. As shown, the relay node 5 10 receives the R-PDSCH message via the receiver module 5丨8. The R-PDSCH message can be provided to the message processing module 516. The R_pDSCH message can be sent using a hybrid automatic repeat request procedure. Therefore, the relay node may need to acknowledge the successful reception of the packet or request a retransmission of the packet that was detected as an error. According to some aspects, the processing module 516 can monitor the reception of the R-PDSCH message and generate a message having a plurality of bits to successfully receive the plurality of downlinks received on the plurality of subframes. Link transmission. According to some aspects, the message processing module 5 16 can generate an N-bit Ack/Nack (A/N) sequence that forms a complex number of downlink transmissions indicating successful and unsuccessful reception by the relay node. The code of one of the possible combinations. According to some aspects, the N bits can be sent to the donor node b 5 10 via the transmitter module 5 12 in a physical uplink control channel (pucch) message or relay pucch (R pucch). The PUCCH message may be 20 201246880 in any suitable format to carry the N A/N bits. For example, the PUCCH message may have a format similar to PUCCH format 2 as defined in LTE Rel-8 (and a/N bits may be sent with channel status information). As another example, a new format can be used in a PUCCH message to send a PUCCH message. According to some aspects, the one bit is determined based on a set of downlink subframes and an uplink subframe set configured between the donor base station and the relay node. According to some aspects, the bits are further determined based on the downlink H-ARQ timing. As an example, the timing between the pDSCH transmission and the aCK/nak transmission is at least 4 ms. As an example, the H-ARQ timing is chosen such that the ACK/NAK payload across different uplink frames is substantially uniform. According to some aspects, the downlink subframe set and the uplink subframe set have an 8 ms period and are configured on a semi-static basis.

Figure 7 illustrates an exemplary operation 700 that may be performed by a half-double according to some aspects of the present disclosure. By way of example, f, the operations may be performed by the relay to acknowledge the downlink subframe sent from the donor base station, = may be performed by the UE to acknowledge the downlink frame from the relay node. At 702, the half-duplex node can receive a plurality of downlink transmissions from the donor base station in a plurality of subframes. In one aspect, half-duplex section 2 may be a mid-node that receives a plurality of DL subframes that need to be relayed to the UE. According to some aspects, the relay node may receive a plurality of physical downlink shared resource (PDSCH) transmissions or physical downlink control channel (PDCCH) transmissions. According to some aspects, the relay node can receive uplink grant information that needs to be relayed to the UE. According to some aspects, the relay node can further determine whether the appropriate hand 9 (for example, error detection information received with the downlink transmission) is used to determine whether a plurality of downlink transmissions have been successfully received. Each downlink transmission. At 7.4, the half-duplex node can transmit an uplink transmission that includes a plurality of bits indicating whether the downlink transmission was successfully received. Depending on the aspect, the plurality of bits may also indicate whether the permissive information was successfully received. According to some aspects, the plurality of bits may be transmitted in a PUCCH format 2 message, a PUCCH message having a format similar to format 2, or a new PUCCH message format. FIG. 8 illustrates an exemplary operation 800 that may be performed by a device in communication with a half-duplex node 22 201246880, in accordance with some aspects of the present disclosure. For example, such operations may be performed by a donor base station in communication with a half-duplex relay node or by a relay node in communication with the UE. At 802, a plurality of downlink transmissions are transmitted to the half-duplex node in a plurality of subframes. At 804, an uplink transmission from a half-duplex node is received, the uplink transmission including a plurality of bits indicating whether the downlink transmission was successfully received. According to some aspects, the relay node may use the PUCCH message to generate HARQ messages based on the mapping. According to one aspect, a format such as PUCCH format 2 or some other new format can be used to convey more bits for HARQ feedback. For example, Table 1 below illustrates an exemplary PUCCH format and how PUCCH messages based on existing PUCCH format 2 carry channel state information and N HARQ-ACK bits.

Bit = specific number may depend on how many coded characters are sent in the DL subframe and the type of diversity (or layer or spatial stream as a specific, non-limiting instance, according to certain aspects, 10 bits can be used to transmit HARQ feedback for multiple transmissions using Format 2. Assuming that separate HARQ feedback is sent for two coded characters and DTX, each DL transmission may require 5 levels. For a single DL subframe, the conventional puccH format i message can be used. For two DL subframes, the pucCH format type message can be used, and the PUCCH format 2 message is reduced to 2 or 5 bits. The spread factor of the element. 24 201246880 Continue with the above For example, since 2 coded characters and 5 levels are used, this can indicate that there are 25 possibilities for the combination of successfully and unsuccessfully received dl transmissions (for example, 2 code characters and $ are assumed) In the case of level 't 5x5 different possible combinations.) 25 possible combinations mean 5 bits is sufficient. On the other hand, for "solid DL subframes, 7 bits can be used (also That is, 5χ5χ5 = 125), and for 4 DL subframes, 10 bits (ie, '5x5x5x5 = 625) can be utilized. These specific configurations are only examples and may depend on the particular implementation of the particular implementation. The design target utilizes a specific number of bits. According to some aspects, the relay node can receive downlink transmissions on a plurality of carriers. According to one aspect, a system employing a multi-carrier backhaul link can be used. The PUCCH supports multiple DL carriers. In one aspect, the PUCCH can carry UL ACK/NACK for multiple DL carriers and multiple subframes. According to one aspect, a new format can be adopted, where HARQ feedback is for multiple Carrier Multiple sub-frames are conveyed. In order to reduce the size of the feedback and support a large number of DL carriers, it can be configured to carry a single acknowledgment for multiple DL carriers and/or coded characters. For example, on multiple carriers The downlink transmissions sent in the shared subframe can be accompanied by a single ACK. As described above, the techniques described herein can also be used in the access link between the relay node and the UE. Exemplary operations 900 that may be performed by the UE. At 902, the UE may receive a plurality of downlink transmissions from the relay node in a plurality of subframes.
