於多重存取無線通訊系統中編碼簿交換之方法及裝置Method and device for encoding book exchange in multiple access wireless communication system

本揭示案大體係關於無線通訊，且更特定言之係關於無線通訊系統(特定言之，多重存取通訊系統)中之編碼簿交換。The present disclosure relates to wireless communication, and more particularly to codebook exchange in wireless communication systems (specifically, multiple access communication systems).

廣泛布署無線通訊系統以提供各種類型之通訊內容，諸如語音、資料等。此等系統可為能夠藉由共用可用系統資源(例如，頻寬及傳輸功率)而支援與多個使用者之通訊之多重存取系統。此等多重存取系統之實例包括分碼多重存取(CDMA)系統、分時多重存取(TDMA)系統、分頻多重存取(FDMA)、第三代合作夥伴計劃－長期演進(3GPP LTE)系統及正交分頻多重存取(OFDMA)系統。Wireless communication systems are widely deployed to provide various types of communication content such as voice, data, and the like. Such systems may be multiple access systems capable of supporting communication with multiple users by sharing available system resources (eg, bandwidth and transmission power). Examples of such multiple access systems include code division multiple access (CDMA) systems, time division multiple access (TDMA) systems, frequency division multiple access (FDMA), third generation partnership programs - Long Term Evolution (3GPP LTE) System and Orthogonal Frequency Division Multiple Access (OFDMA) systems.

通常，無線多重存取通訊系統可同時支援多個無線終端機之通訊。每一終端機經由前向鏈路及反向鏈路上之傳輸與本文中稱為存取點或基地台之一或多個存取網路通訊。前向鏈路(或下行鏈路)係指自存取網路至終端機之通訊鏈路，且反向鏈路(或上行鏈路)係指自終端機至存取網路之通訊鏈路。此通訊鏈路可經由單入單出、多入單出或多入多出(MIMO)系統而建立。Generally, a wireless multiple access communication system can simultaneously support communication of multiple wireless terminals. Each terminal communicates with one or more access networks, referred to herein as access points or base stations, via transmissions on the forward and reverse links. The forward link (or downlink) refers to the communication link from the access network to the terminal, and the reverse link (or uplink) refers to the communication link from the terminal to the access network. . This communication link can be established via a single-input single-out, multiple-input single-out or multiple-input multiple-output (MIMO) system.

MIMO系統使用多個(N _T )傳輸天線及多個(N _R )接收天線用於資料傳輸。由N _T 個傳輸天線及N _R 個接收天線形成之MIMO通道可分解成N _S 個獨立通道，該等獨立通道亦被稱作空間通道，其中N _S min{N _T ,N _R }。N _S 個獨立通道中之每一者對應於一空間維度。若利用由多個傳輸天線及接收天線所建立之額外維度，則MIMO系統可提供改良之效能(例如，較高峰率及/或覆蓋性)。MIMO systems use multiple (N _T) transmit antennas and multiple (N _R) receive antennas for data transmission. The MIMO channel formed by the N _T transmit antennas and N _R receive antennas may be decomposed into N _S independent channels, such independent channel has also been referred to as spatial channels, where N _S Min{ N _T , N _R }. Each of the N _S independent channels corresponds to a spatial dimension. The MIMO system can provide improved performance (e.g., higher peak rate and/or coverage) if the additional dimensions established by multiple transmit and receive antennas are utilized.

MIMO可同時用於分時雙工(TDD)系統與分頻雙工(FDD)系統。在TDD系統中，前向鏈路傳輸及反向鏈路傳輸處於同一頻率區上，使得互反性原理允許自反向鏈路通道估計前向鏈路通道。此使存取網路在多個天線可用於存取網路處時能夠擷取前向鏈路上之傳輸波束形成增益。MIMO can be used in both time division duplex (TDD) systems and frequency division duplex (FDD) systems. In a TDD system, the forward link transmission and the reverse link transmission are on the same frequency region, such that the reciprocity principle allows the forward link channel to be estimated from the reverse link channel. This enables the access network to capture the transmit beamforming gain on the forward link when multiple antennas are available to access the network.

分域多重存取(SDMA)系統視發射器處之多個天線而定。SDMA依賴於使用者之空間資訊，且基於使用者之空間位置對其加以分類。SDMA與諸如TDMA、FDMA、CDMA等之任何多重存取機制相容。A Domain Multiple Access (SDMA) system depends on multiple antennas at the transmitter. SDMA relies on the user's spatial information and classifies it based on the user's spatial location. SDMA is compatible with any multiple access mechanism such as TDMA, FDMA, CDMA, and the like.

分域多重存取(SDMA)使得能夠經由空間多工建立平行高容量空間管道，以提供無線電多重存取無線通訊系統中之優異效能。藉由使用MIMO技術並利用小區內之行動單元之位置的空間資訊，已開發SDMA技術。對每一使用者就傳輸與接收兩者調適存取網路之輻射場型以獲取行動使用者之方向上之最高增益。常常使用相陣技術來進行此調適。Domain Division Multiple Access (SDMA) enables the creation of parallel high-capacity space pipes via spatial multiplexing to provide superior performance in radio multiple access wireless communication systems. SDMA technology has been developed by using MIMO technology and utilizing spatial information of the location of mobile units within a cell. For each user, both the transmission and reception are adapted to the radiation pattern of the access network to obtain the highest gain in the direction of the mobile user. Phased array techniques are often used for this adaptation.

預編碼為達成MIMO系統中之普遍波束形成之方法。預編碼使來自傳輸天線之多個信號流能夠具有獨立且適當之加權，使得整個鏈路可在接收器輸出處被最大化。Precoding is a method of achieving universal beamforming in a MIMO system. Precoding enables multiple signal streams from the transmit antenna to be independently and appropriately weighted such that the entire link can be maximized at the receiver output.

預編碼界定自實體天線至傳輸至特定使用者之信號的映射，但使用者不注意實體天線場型，且自由預編碼器界定之有效天線接收信號。特定映射由預編碼矩陣界定。預編碼矩陣之行界定可由存取網路使用之一組空間波束。存取網路在單輸入單輸出(SISO)傳輸中僅使用預編碼矩陣之一個行(例如，一個有效天線)，且在MIMO傳輸中使用多個行(例如，多個有效天線)。The precoding defines a mapping from the physical antenna to the signal transmitted to the particular user, but the user does not pay attention to the physical antenna pattern and the effective antenna defined by the free precoder receives the signal. A particular mapping is defined by a precoding matrix. The row of precoding matrices defines a set of spatial beams that can be used by the access network. The access network uses only one row of the precoding matrix (eg, one active antenna) in a single-input single-output (SISO) transmission, and uses multiple rows (eg, multiple active antennas) in MIMO transmission.

判定有效天線，且因此判定預編碼矩陣視建構及布署而定。布署涉及許多瞬間因素，諸如存取終端機之位置、環境條件、時刻等。因此，對於每一布署，可能需要預編碼矩陣之不同集合。網路布局、實體地形等可影響預編碼矩陣之集合的選擇。此預編碼矩陣之集合形成編碼簿。The effective antenna is determined, and thus the precoding matrix is determined to depend on the construction and deployment. Deployment involves many transient factors, such as the location of the access terminal, environmental conditions, time of day, and so on. Therefore, for each deployment, different sets of precoding matrices may be required. Network layout, solid terrain, etc. can influence the selection of a set of precoding matrices. The set of precoding matrices form an encoded book.

鑒於至少上述問題，需要用以在存取網路與存取終端機之間有效且高效地交換編碼簿之系統及/或方法。In view of at least the above problems, systems and/or methods are needed for efficiently and efficiently exchanging codebooks between an access network and an access terminal.

編碼簿106包括具有可對應於多個傳輸模式之不同向量及/或矩陣之輸入項，此資訊可預先界定。每一輸入項可對應於一傳輸模式或一空間處理形式(例如，預編碼、SDMA、MIMO等)。舉例而言，編碼簿106可含有一組64個輸入項，然而，可存在任何數目之輸入項且64為任意數目。根據本發明之態樣，編碼簿106可經定製用於存取網路104或扇區或與存取網路104通訊之一或多個存取終端機102。舉例而言且並非用於限制目的，編碼簿106可支援應用多個傳輸模式之複數個使用者。應注意，儘管在本發明之態樣中展示一個編碼簿106，但在系統100中可存在一個以上編碼簿，且一個以上編碼簿106可與給定布署相關聯。The codebook 106 includes entries having different vectors and/or matrices that may correspond to multiple transmission modes, this information may be predefined. Each entry may correspond to a transmission mode or a spatial processing format (eg, precoding, SDMA, MIMO, etc.). For example, the codebook 106 can contain a set of 64 entries, however, there can be any number of entries and 64 is any number. In accordance with aspects of the present invention, the codebook 106 can be customized for accessing the network 104 or sector or communicating with the access network 104 for one or more access terminals 102. For example and not for purposes of limitation, the codebook 106 can support a plurality of users applying multiple transmission modes. It should be noted that although one codebook 106 is shown in the context of the present invention, more than one codebook may be present in system 100, and more than one codebook 106 may be associated with a given deployment.

存取終端機102可向存取網路104通知存取終端機102將首選之編碼簿輸入項。視通訊系統要求而定，編碼簿106可為存取終端機102與存取網路104中之任一者或兩者所知。在關於本發明之態樣之系統中，編碼簿106將由存取網路104產生，被傳達至存取終端機102且被儲存於存取終端機快取記憶體中(亦即，臨時儲存)。因此，在本發明之態樣中，編碼簿106同時為存取網路104與存取終端機102兩者所知。當存取終端機102在不同存取網路104之間移動時，存取終端機102可獲取並應用一與彼特定地理區中之存取網路104相關聯的不同編碼簿106。可藉由存取終端機102自主地(例如，藉由處理器存取不同編碼簿)或藉由存取網路104向存取終端機102通知一新指派來自動地執行新編碼簿106之獲取及/或指派。The access terminal 102 can notify the access network 104 that the access terminal 102 will enter the preferred codebook entry. Depending on the requirements of the communication system, the codebook 106 can be known to either or both of the access terminal 102 and the access network 104. In a system relating to aspects of the present invention, the codebook 106 will be generated by the access network 104, communicated to the access terminal 102 and stored in the access terminal cache memory (i.e., temporarily stored). . Thus, in the aspect of the invention, the codebook 106 is known to both the access network 104 and the access terminal 102. As the access terminal 102 moves between different access networks 104, the access terminal 102 can acquire and apply a different codebook 106 associated with the access network 104 in a particular geographic area. The new codebook 106 can be automatically executed by the access terminal 102 autonomously (e.g., by the processor accessing a different codebook) or by the access network 104 notifying the access terminal 102 of a new assignment. Get and/or assign.

在SDMA中，多個使用者可在其空間簽名可能不同之相同時間頻頻資源上得以同時排程。在SDMA中，一扇區被分成虛擬扇區，使得不同區域中之使用者設備共用相同通道資源，藉此達成較高空間再用。因此，在SDMA中，可存在潛在地提供強健信號傳輸之分離傳輸模式。可使用此傳輸模式來傳輸控制及/或廣播資料。每一虛擬扇區可進一步再分為一組較窄空間波束，使得虛擬扇區內之特定波束(或波束之線性組合)可應用於特定使用者設備，藉此增加對使用者設備之天線增益並限制由傳輸產生之干擾之空間展布。In SDMA, multiple users can schedule simultaneously on the same time-frequency resources whose spatial signatures may be different. In SDMA, a sector is divided into virtual sectors so that user equipment in different areas share the same channel resources, thereby achieving higher spatial reuse. Thus, in SDMA, there may be separate transmission modes that potentially provide robust signal transmission. This transmission mode can be used to transmit control and/or broadcast data. Each virtual sector can be further subdivided into a set of narrower spatial beams such that a particular beam (or linear combination of beams) within the virtual sector can be applied to a particular user equipment, thereby increasing antenna gain to the user equipment. And limit the spatial distribution of interference caused by transmission.

當容量處於非線性區附近時，SDMA可用於高SNR情境。在此等態樣中，使多個使用者重疊以降低每一使用者之SNR為代價而增加可用通道之數目(維度)。假定在高SNR下使用者處於非線性容量區，則此方法增加系統容量。另一方面，在低SNR能譜(容量曲線之線性區)中，減弱使用者能力同時增加維度通常無益。在此等態樣中，藉由諸如預編碼可在多個資訊流上進行之預編碼(MIMO預編碼)的技術來增加使用者之SNR為有益的。此等態樣利用預定組波束來傳輸至使用者。在MIMO機制中，存在傳輸至同一使用者之多個流，其中資料可沿多個固有向量方向傳輸。SDMA can be used for high SNR scenarios when capacity is near a non-linear region. In such aspects, the number (dimensions) of available channels is increased at the expense of reducing the SNR of each user by having multiple users overlap. This approach increases system capacity assuming that the user is in a non-linear capacity region at high SNR. On the other hand, in the low SNR spectrum (linear region of the capacity curve), it is usually not beneficial to reduce the user's ability while increasing the dimension. In such aspects, it may be beneficial to increase the SNR of the user by techniques such as precoding precoding (MIMO precoding) over multiple information streams. These aspects are transmitted to the user using a predetermined set of beams. In the MIMO mechanism, there are multiple streams transmitted to the same user, where the data can be transmitted in multiple intrinsic vector directions.

利用所揭示之技術，藉由在SDMA波束之波束空間中應用預編碼可致能多輸入單輸出/多輸入多輸出(MISO/MIMO)預編碼與SDMA之無縫操作。特定言之，若存在允用SDMA之少數虛擬扇區，則每一此區域進一步由一組較窄空間波束組成。此等較窄波束形成發生於彼虛擬扇區內之傳輸之基礎。With the disclosed techniques, seamless operation of multiple input single output/multiple input multiple output (MISO/MIMO) precoding and SDMA can be enabled by applying precoding in the beam space of the SDMA beam. In particular, if there are a few virtual sectors that allow SDMA, each of these regions is further composed of a set of narrower spatial beams. These narrower beamformings occur on the basis of transmissions within the virtual sector.

關於應利用哪一模式(預編碼、SDMA、MIMO或其組合)之決策可基於一或多個通道條件。可使用通道品質指示(CQI)技術來判定應使用哪一向量，例如提供最高或最低值。對於預編碼，可利用預處理使用者之傳輸之特定輸入項。對於MIMO預編碼，可利用一組向量來預處理存取網路之傳輸。預編碼提供較高SNR，從而潛在地產生較高峰率及較好覆蓋性。The decision as to which mode (precoding, SDMA, MIMO, or a combination thereof) should be utilized may be based on one or more channel conditions. Channel Quality Indication (CQI) techniques can be used to determine which vector should be used, such as providing the highest or lowest value. For precoding, specific inputs for the transmission of the pre-processing user can be utilized. For MIMO precoding, a set of vectors can be utilized to preprocess the transmission of the access network. Precoding provides a higher SNR, potentially resulting in higher peak rates and better coverage.

參看圖2，根據本發明之態樣，描繪詳述一編碼簿200之例示性結構之方塊圖。編碼簿200可包括下述參數之部分但非所有。舉例而言，編碼簿200可包括用以區分該編碼簿與其他編碼簿之編碼簿識別符202。在某些態樣中，編碼簿識別符202可為由存取網路指派之16位元數量識別符。16位元編碼簿識別符保證編碼簿識別在各個供應商之間的最小衝突。然而，本文所揭示之態樣不限於16位元編碼簿識別符組態，且其他位元長度編碼簿識別符亦係可能的，且屬於所揭示態樣之範疇內。如以下將詳細描述的，可在編碼簿交換及指派期間使用編碼簿識別符202以自存取終端機快取記憶體驗證並擷取必要編碼簿。Referring to Figure 2, a block diagram detailing an exemplary structure of an encoder 200 is depicted in accordance with an aspect of the present invention. The codebook 200 may include some but not all of the following parameters. For example, the codebook 200 can include a codebook identifier 202 to distinguish the codebook from other codebooks. In some aspects, the codebook identifier 202 can be a 16-bit quantity identifier assigned by the access network. The 16-bit codebook identifier ensures that the codebook identifies the smallest conflict between the various vendors. However, the aspects disclosed herein are not limited to 16-bit codebook identifier configurations, and other bit length codebook identifiers are also possible and fall within the scope of the disclosed aspects. As will be described in greater detail below, the codebook identifier 202 can be used during codebook exchange and assignment to self-access terminal cache memory verification and retrieve the necessary codebook.

另外，編碼簿200可包括一將編碼簿中之波束編入索引之波束索引參數204。因此，波束索引參數204可(作為實例)指示下列各項中之一或多者：(1)無較佳預編碼或SDMA矩陣；(2)空間波束上之較佳單輸入單輸出(SISO)預編碼或SDMA傳輸；及(3)一組空間波束(例如，預編碼矩陣之一個以上行)上之較佳多輸入多輸出(MIMO)預編碼或SDMA傳輸。波束索引參數204亦可指示一或多組允許重疊波束。Additionally, the codebook 200 can include a beam index parameter 204 that indexes the beams in the codebook. Thus, beam indexing parameter 204 can (by way of example) indicate one or more of the following: (1) no better precoding or SDMA matrix; (2) better single input single output (SISO) on spatial beam Precoding or SDMA transmission; and (3) preferred multiple input multiple output (MIMO) precoding or SDMA transmission over a set of spatial beams (eg, more than one row of precoding matrices). Beam indexing parameters 204 may also indicate that one or more sets of allowed overlapping beams.

編碼簿200亦可包括識別由存取網路建構之天線之最大數目的傳輸天線參數206。另外，編碼簿200亦可包括識別通訊系統中所支援之層之最大數目的所支援層參數208。所支援層之最大數目在此項技術中可另外稱為空間次序。天線之最大數目及最大所支援層用以界定預編碼矩陣之大小。因此，可將預編碼矩陣之大小界定為傳輸天線之最大數目與所支援層之最大數目之乘積。The codebook 200 can also include a transmission antenna parameter 206 that identifies the maximum number of antennas constructed by the access network. In addition, the codebook 200 can also include a support layer parameter 208 that identifies the maximum number of layers supported in the communication system. The maximum number of supported layers may be additionally referred to as spatial order in the art. The maximum number of antennas and the largest supported layer are used to define the size of the precoding matrix. Thus, the size of the precoding matrix can be defined as the product of the maximum number of transmit antennas and the maximum number of supported layers.

編碼簿200可另外包括識別編碼簿中之預編碼矩陣之數目的預編碼矩陣參數210。如先前所指出，編碼簿200通常可包括64個預編碼矩陣；然而，亦可組態其他數量之預編碼矩陣。The codebook 200 may additionally include precoding matrix parameters 210 that identify the number of precoding matrices in the codebook. As noted previously, the codebook 200 may typically include 64 precoding matrices; however, other numbers of precoding matrices may be configured.

另外，編碼簿200將包括提供有效天線與實體天線之間的較佳映射之複數個較佳預編碼矩陣212。In addition, the codebook 200 will include a plurality of preferred precoding matrices 212 that provide a preferred mapping between the active antenna and the physical antenna.

編碼簿200可另外提供叢集。將叢集界定為由覆蓋空間界定之一組預編碼矩陣(例如，一組波束)。不同叢集中之矩陣之行用以形成空間上覆蓋不同組使用者/存取終端機之空間波束。若存取終端機反饋一叢集內之波束索引，則存取網路會將此看作其可對不同叢集上之其他存取終端機進行排程(亦即，允許SDMA發生)之指示。因而，編碼簿200可包括一界定編碼簿中之叢集之數目的叢集參數214。每一叢集將具有一識別該叢集中之波束之數目的叢集子參數216。叢集中之波束之數目可由起始波束索引及結束波束索引識別。The codebook 200 may additionally provide a cluster. The cluster is defined as a set of precoding matrices (eg, a set of beams) defined by the coverage space. The rows of matrices in different clusters are used to form spatial beams that spatially cover different sets of users/access terminals. If the access terminal feeds back the beam index within a cluster, the access network will see this as an indication that it can schedule other access terminals on different clusters (i.e., allow SDMA to occur). Thus, the codebook 200 can include a cluster parameter 214 that defines the number of clusters in the codebook. Each cluster will have a cluster sub-parameter 216 that identifies the number of beams in the cluster. The number of beams in the cluster can be identified by the starting beam index and the ending beam index.

另外，編碼簿200可包括一指示經授權以潛在地重疊之叢集的叢集重疊映射218。叢集重疊映射218可形成為大小為(預編碼矩陣數目)×(預編碼矩陣數目)之矩陣。因此，對於具有64個預編碼矩陣之編碼簿，叢集重疊映射可具有大小為4096之矩陣。重疊映射矩陣可經形成使得"1"可指示允許之重疊且"0"可指示無容許之重疊。另外，存取終端機應在向存取網路報告通道品質指示(CQI)時考慮重疊之叢集。Additionally, the codebook 200 can include a cluster overlay map 218 indicating clusters that are authorized to potentially overlap. The cluster overlap map 218 may be formed into a matrix of size (number of precoding matrices) x (number of precoding matrices). Thus, for an encoded book with 64 precoding matrices, the cluster overlay map can have a matrix of size 4096. The overlapping mapping matrices may be formed such that "1" may indicate an allowed overlap and "0" may indicate an unallowed overlap. In addition, the access terminal should consider overlapping clusters when reporting channel quality indications (CQI) to the access network.

圖3提供在多重存取無線通訊系統中產生並交換編碼簿之方法300之流程圖。應瞭解，方法300可由(例如)存取網路(例如，存取網路104)及/或任何其他適當網路實體執行。在步驟302處，提供複數個較佳預編碼矩陣。舉例而言，在一態樣中，可提供64個預編碼矩陣。每一矩陣將界定有效天線與實體天線之間的映射，且因此提供波束形成。存取終端機將基於建構及布署因素自該複數個較佳預編碼矩陣中選擇一預編碼矩陣。3 provides a flow diagram of a method 300 of generating and exchanging codebooks in a multiple access wireless communication system. It should be appreciated that method 300 can be performed by, for example, an access network (e.g., access network 104) and/or any other suitable network entity. At step 302, a plurality of preferred precoding matrices are provided. For example, in one aspect, 64 precoding matrices may be provided. Each matrix will define a mapping between the active antenna and the physical antenna and thus provide beamforming. The access terminal will select a precoding matrix from the plurality of preferred precoding matrices based on the construction and deployment factors.

在步驟304處，在存取網路處產生一編碼簿。該編碼簿包括複數個較佳預編碼矩陣。另外，所產生編碼簿可包括編碼簿識別符，諸如16位元編碼簿識別符或任何其他適合位元長度編碼簿識別符。所產生編碼簿可包括界定為預編碼矩陣之分組之叢集的識別。除編碼簿中之叢集之數目外，編碼簿可包括指示叢集中之波束之數目的叢集波束索引、起始波束索引及結束波束索引。在某些態樣中，所產生編碼簿可另外包括識別重疊叢集之叢集重疊映射。At step 304, an codebook is generated at the access network. The codebook includes a plurality of preferred precoding matrices. Additionally, the generated codebook may include an encoded book identifier, such as a 16-bit code book identifier or any other suitable bit length codebook identifier. The generated codebook may include an identification of a cluster defined as a grouping of precoding matrices. In addition to the number of clusters in the codebook, the codebook may include a cluster beam index, a starting beam index, and an end beam index indicating the number of beams in the cluster. In some aspects, the generated codebook may additionally include a cluster overlay map that identifies overlapping clusters.

在步驟306處，將編碼簿傳達至當前位於存取網路之接收範圍內之一或多個存取終端機。在可選步驟308處，為該或該等存取終端機指派編碼簿。編碼簿之傳達可與編碼簿之指派一致，或指派可獨立於編碼簿之傳達而發生。以下將論述之圖4提供編碼簿傳達及指派之詳細方法。At step 306, the codebook is communicated to one or more access terminals currently within the receiving range of the access network. At optional step 308, an encoding book is assigned to the or the access terminals. The communication of the codebook may be consistent with the assignment of the codebook, or the assignment may occur independently of the communication of the codebook. Figure 4, which will be discussed below, provides a detailed method of codebook communication and assignment.

圖4為根據本發明之態樣之用於多重存取無線通訊系統中之編碼簿交換及指派的方法400之流程圖。應瞭解，方法400可由(例如)存取網路(例如，基地台104)及/或任何其他適當網路實體執行。在步驟402處，存取網路將編碼簿狀態查詢訊息傳達至存取終端機。在前向鏈路上傳達編碼簿狀態查詢訊息。編碼簿狀態查詢可由新增至存取網路之有效集合的每一新存取網路來傳達。4 is a flow diagram of a method 400 for codebook exchange and assignment in a multiple access wireless communication system in accordance with aspects of the present invention. It should be appreciated that method 400 can be performed by, for example, an access network (e.g., base station 104) and/or any other suitable network entity. At step 402, the access network communicates the codebook status query message to the access terminal. The codebook status query message is conveyed on the forward link. The codebook status query can be communicated by each new access network added to the active set of access networks.

在步驟404處，存取網路接收指示當前儲存於存取終端機之快取記憶體中之編碼簿的編碼簿狀態回應。編碼簿狀態回應係在反向鏈路上傳達且根據相應編碼簿識別符識別快取編碼簿。藉由向每一存取網路(諸如基地台)提供查詢存取終端機以用於當前編碼簿指派之能力，無需與其他存取網路共用存取終端機編碼簿快取狀態。此減小必須在存取網路之間共用的會話資訊的大小及複雜性。At step 404, the access network receives a codebook status response indicating the codebook currently stored in the cache memory of the access terminal. The codebook status response is conveyed on the reverse link and identifies the cache codebook based on the corresponding codebook identifier. By providing each access network (such as a base station) with the ability to query access terminals for current codebook assignments, there is no need to share access terminal codebook cache status with other access networks. This reduces the size and complexity of the session information that must be shared between access networks.

在決策步驟406處，存取網路判定存取終端機當前是否具有存取終端機快取記憶體中之相關聯之編碼簿。藉由檢查與編碼簿狀態回應中之存取網路相關聯之編碼簿識別符來執行此判定。若判定存取終端機當前不具有存取終端機快取記憶體中之編碼簿，則在步驟408處，存取終端機將編碼簿傳達至存取終端機。存取網路可將編碼簿作為編碼簿設置訊息之部分而在前向鏈路上傳達。At decision step 406, the access network determines whether the access terminal currently has access to the associated codebook in the terminal cache memory. This determination is performed by examining the codebook identifier associated with the access network in the codebook status response. If it is determined that the access terminal does not currently have access to the codebook in the terminal cache, then at step 408, the access terminal communicates the codebook to the access terminal. The access network communicates the codebook on the forward link as part of the codebook setup message.

在步驟408處，一旦已將編碼簿傳達至存取終端機或在判定編碼簿當前儲存於存取終端機快取記憶體中之後，存取網路即可將編碼簿指派至存取終端機。指派編碼簿提供為有效集合中之特定扇區建構編碼簿。在前向鏈路上傳達編碼簿指派。At step 408, once the codebook has been communicated to the access terminal or after determining that the codebook is currently stored in the access terminal cache, the access network can assign the codebook to the access terminal. . The assignment codebook provides for building a codebook for a particular sector in the active set. The codebook assignment is conveyed on the forward link.

圖7提供在多重存取無線通訊系統中於存取終端機處接收並儲存編碼簿之方法700之流程圖。應瞭解，方法700可由(例如)存取終端機及/或與存取網路無線通訊之任何其他適當設備執行。在步驟702處，存取終端機接收包括複數個較佳預編碼矩陣之編碼簿。如關於以下論述之圖8所述，編碼簿之接收可由狀態查詢及隨後回應誘發。編碼簿之接收可發生於前向鏈路上。7 provides a flow diagram of a method 700 of receiving and storing an encoded book at an access terminal in a multiple access wireless communication system. It should be appreciated that method 700 can be performed by, for example, an access terminal and/or any other suitable device that wirelessly communicates with an access network. At step 702, the access terminal receives an encoded book comprising a plurality of preferred precoding matrices. As described with respect to Figure 8 of the following discussion, the receipt of the codebook can be induced by a status query and subsequent responses. The receipt of the codebook can occur on the forward link.

在步驟704處，所接收編碼簿根據編碼簿中所包括之編碼簿識別而儲存於編碼簿快取記憶體中。通常，若存取終端機在接收編碼簿時處於閒置狀態，則存取終端機可經組態以快取編碼簿，或在替代態樣中，存取終端機可經組態以不予處理編碼簿快取輸入項。另外，存取終端機可經組態以在終端機被切斷電源或以其他方式經歷重新啟動時自快取記憶體刪除編碼簿。又，在編碼簿被快取於非揮發性記憶體中之情況下，存取終端機可經組態以在無電源(例如，電池)後即自記憶體刪除編碼簿。在此等態樣中，電源之復原通常將要求存取終端機自存取網路重新獲取所需編碼簿以視需要復原編碼簿快取記憶體。At step 704, the received codebook is stored in the codebook cache in accordance with the codebook identification included in the codebook. Typically, if the access terminal is idle while receiving the codebook, the access terminal can be configured to cache the codebook, or in an alternative aspect, the access terminal can be configured to not process Codebook cache entry. Additionally, the access terminal can be configured to delete the codebook from the cache memory when the terminal is powered off or otherwise undergoes a reboot. Also, where the codebook is cached in non-volatile memory, the access terminal can be configured to delete the codebook from the memory after no power source (e.g., battery). In such aspects, the restoration of the power supply will typically require the access terminal to re-acquire the desired codebook from the access network to restore the codebook cache memory as needed.

在可選步驟706處，對於儲存於編碼簿快取記憶體中之編碼簿接收編碼簿指派。該指派將已識別編碼簿指派至通訊鏈路之有效集合中之預定扇區。編碼簿之指派可與編碼簿之傳達一起發生，或指派可發生於編碼簿已被傳達並儲存於存取終端機處之後的任何時間點處。存取終端機通常經組態以保持(亦即，不刪除)當前由通訊鏈路之有效集合中之扇區指派的任何快取輸入項。At optional step 706, a codebook assignment is received for a codebook stored in the codebook cache. The assignment assigns the identified codebook to a predetermined sector in the active set of communication links. The assignment of the codebook may occur with the communication of the codebook, or the assignment may occur at any point in time after the codebook has been communicated and stored at the access terminal. The access terminal is typically configured to maintain (ie, not delete) any cache entry currently assigned by a sector in the active set of communication links.

圖8為根據本發明之態樣之在多重存取無線通訊系統中於存取終端機處接收並指派編碼簿的方法800之流程圖。應瞭解，方法800可由(例如)存取終端機及/或與存取網路無線通訊之任何其他適當設備執行。在步驟802處，存取終端機接收自存取網路傳達之編碼簿狀態查詢訊息。可在前向鏈路上傳達編碼簿狀態查詢訊息。編碼簿狀態查詢可由新增至存取網路之有效集合的每一新存取網路來傳達。8 is a flow diagram of a method 800 of receiving and assigning an encoded book at an access terminal in a multiple access wireless communication system in accordance with an aspect of the present invention. It should be appreciated that method 800 can be performed by, for example, an access terminal and/or any other suitable device that wirelessly communicates with the access network. At step 802, the access terminal receives the codebook status query message communicated from the access network. The codebook status query message can be conveyed on the forward link. The codebook status query can be communicated by each new access network added to the active set of access networks.

在步驟804處，將指示當前儲存於存取終端機之快取記憶體中之編碼簿的編碼簿狀態回應傳達至存取網路。編碼簿狀態回應可於反向鏈路上傳達且根據相應編碼簿識別符識別快取編碼簿。藉由向每一存取網路(諸如基地台)提供查詢存取終端機以用於當前編碼簿指派之能力，無需與其他存取網路共用存取終端機編碼簿快取狀態。此減小必須在存取網路之間共用之會話資訊的大小及複雜性。At step 804, a codebook status response indicating the codebook currently stored in the cache memory of the access terminal is communicated to the access network. The codebook status response can be communicated on the reverse link and the cache codebook is identified based on the corresponding codebook identifier. By providing each access network (such as a base station) with the ability to query access terminals for current codebook assignments, there is no need to share access terminal codebook cache status with other access networks. This reduction must be the size and complexity of the session information that must be shared between access networks.

在步驟806處，若對編碼簿狀態查詢之回應指示與起始查詢之存取網路相關聯之編碼簿當前不儲存於存取終端機之編碼簿快取記憶體中，則由存取終端機接收編碼簿。存取網路可將編碼簿作為編碼簿設置訊息之部分而於前向鏈路上接收。At step 806, if the response to the codebook status query indicates that the codebook associated with the access network of the initial query is not currently stored in the codebook cache memory of the access terminal, then the access terminal The machine receives the code book. The access network can receive the codebook as part of the codebook setup message on the forward link.

在步驟808處，一旦編碼簿已由存取終端機接收，終端機即可接收為通訊鏈路之有效集合中之特定扇區指派編碼簿的編碼簿指派。可在前向鏈路上傳達編碼簿指派。At step 808, once the codebook has been received by the access terminal, the terminal can receive a codebook assignment that assigns a codebook for a particular sector in the active set of communication links. Codebook assignments can be conveyed on the forward link.

The apparatus and method of the present invention are thus applicable to any form of wireless communication device or wireless computer module (including wireless communication portals (including but not limited to wireless data machines, PCMCIA cards, wireless devices, or any combination or sub-combination thereof)) Execute on.

存取終端機1000包括至少一處理器1002及耦接至處理器1002之記憶體1004。處理器1002可為特殊應用積體電路("ASIC")，或其他晶片組、處理器、邏輯電路或其他資料處理設備。記憶體1004可包含揮發性及非揮發性記憶體，諸如唯讀記憶體及/或隨機存取記憶體(ROM及RAM)、EPROM、EEPROM、快閃記憶卡或為電腦平臺共用之任何記憶體。另外，記憶體1004可包括一或多個快閃記憶體單元，或可為任何第二級或第三級儲存設備，諸如磁性媒體、光學媒體、磁帶，或軟碟或硬碟。The access terminal 1000 includes at least one processor 1002 and a memory 1004 coupled to the processor 1002. Processor 1002 can be a special application integrated circuit ("ASIC"), or other chipset, processor, logic circuit, or other data processing device.

Additionally, memory 1004 can include one or more flash memory units, or can be any second or third level storage device such as magnetic media, optical media, magnetic tape, or floppy or hard disk.

存取終端機1000另外包括一儲存於記憶體1004中且可由至少處理器1002執行之編碼簿模組1006。編碼簿模組1006可操作以接收包括複數個較佳預編碼矩陣之編碼簿。另外，編碼簿模組1006可操作以接收並回應編碼簿查詢以向存取網路通知當前快取之編碼簿。又，編碼簿模組1006可操作以將快取編碼簿中之一者指派至通訊鏈路之有效集合之預定扇區。The access terminal 1000 additionally includes a codebook module 1006 that is stored in the memory 1004 and executable by at least the processor 1002. The codebook module 1006 is operative to receive an encoded book comprising a plurality of preferred precoding matrices. Additionally, the codebook module 1006 is operative to receive and respond to the codebook query to notify the access network of the currently cached codebook. Again, the codebook module 1006 is operative to assign one of the cached codebooks to a predetermined sector of an active set of communication links.

存取終端機1000另外包括一儲存於記憶體1004中且可由至少處理器1002執行之編碼簿快取記憶體1008。編碼簿快取記憶體1008可操作以將所接收編碼簿儲存於記憶體中。如先前所指出，所接收編碼簿將保持於快取記憶體中歷時電力開啟週期之持續時間，且可在閒置狀態期間置放於快取記憶體中。存取終端機可另外經組態以基於存取終端機位置或最大時間設定刪除編碼簿；然而，通常可不自快取記憶體刪除所指派編碼簿。The access terminal 1000 additionally includes a codebook cache memory 1008 that is stored in the memory 1004 and executable by at least the processor 1002. The codebook cache memory 1008 is operative to store the received codebook in memory.

圖11為根據本發明之態樣之單碼字組(SCW)多輸入多輸出(MIMO)中之發射器1100(例如，存取網路)之方塊圖表示。輸入資料流與使用自速率預測模組1106輸入之選定碼率的渦輪碼編碼器1102通訊。接著在正交調幅(QMA)映射模組1104處將渦輪碼編碼資料流映射至選定QAM星象圖。接著在解多工器1108處將調變符號流解多工為平行子流。使用有效天線信號傳輸模組1110將由解多工器1108輸出之M 數目(M 由接收器1118界定)之子流映射至實體天線，從而使速率及等級適應於通道實現。子流接著在個別正交分頻多工(OFDM)調變器1112、1114及1116處經歷個別OFDM調變。一旦被調變，子流經由相應天線1120、1122及1124傳輸。11 is a block diagram representation of a transmitter 1100 (e.g., an access network) in single codeword group (SCW) multiple input multiple output (MIMO) in accordance with aspects of the present invention. The input data stream is in communication with a turbo code encoder 1102 that uses the selected code rate input from the rate prediction module 1106. The turbo coded data stream is then mapped to a selected QAM star map at a Quadrature Amplitude Modulation (QMA) mapping module 1104. The modulated symbol stream is then multiplexed into a parallel substream at the demultiplexer 1108. The sub-streams of the M number ( M defined by the receiver 1118) output by the demultiplexer 1108 are mapped to the physical antenna using the effective antenna signal transmission module 1110, thereby adapting the rate and level to the channel implementation. The substreams then undergo individual OFDM modulation at individual orthogonal frequency division multiplexing (OFDM) modulators 1112, 1114, and 1116. Once modulated, the substreams are transmitted via respective antennas 1120, 1122, and 1124.

圖12為根據本發明之態樣之單碼字組(SCW)多輸入多輸出(MIMO)中之接收器1200(例如，存取終端機)之方塊圖表示。所傳輸子流跨越天線1202、1204及1206被接收且在相應OFDM解調變器1206、1208及1210處經歷OFDM解調變。隨後將經解調變之子流傳達至對所接收解調變子流實施線性最小均方誤差(MMSE)濾波之MMSE模組1212。將線性MMSE濾波之結果傳達至等級預測CQI量化模組1214用於等級與CQI判定。MMSE模組1212與並行變串行模組1216一起解耦傳入之M個子流，且提供調變符號之軟估計。接著將調變符號之軟估計傳達至LLR電腦1218，且將輸出傳達至渦輪碼解碼器1220，從而產生解碼位元。接收器可使用更為複雜之偵測器；然而，在僅使用線性MMSE之情況下，複雜性可相對較低。Figure 12 is a block diagram representation of a receiver 1200 (e.g., an access terminal) in single codeword group (SCW) multiple input multiple output (MIMO) in accordance with aspects of the present invention. The transmitted substreams are received across antennas 1202, 1204, and 1206 and undergo OFDM demodulation at respective OFDM demodulators 1206, 1208, and 1210. The demodulated substream is then conveyed to an MMSE module 1212 that performs linear minimum mean square error (MMSE) filtering on the received demodulated variable substream. The results of the linear MMSE filtering are communicated to the level prediction CQI quantization module 1214 for level and CQI determination. The MMSE module 1212 decouples the incoming M substreams with the parallel variable serial module 1216 and provides a soft estimate of the modulated symbols. The soft estimate of the modulation symbol is then communicated to the LLR computer 1218 and the output is communicated to the turbo code decoder 1220 to produce a decoded bit. The receiver can use a more complex detector; however, in the case of using only linear MMSE, the complexity can be relatively low.

圖13說明例示性多重存取無線通訊系統。多重存取無線通訊系統1300包括多個小區，例如小區1302、1304及1306。在圖13中所說明之例示性系統中，每一小區1302、1304及1306可包括一包括多個扇區之存取點1350。多個扇區由各自負責與小區之一部分中之存取終端機通訊的若干天線群組形成。在小區1302中，天線群組1312、1314及1316各自對應於一不同扇區。在小區1304中，天線群組1318、1320及1322各自對應於一不同扇區。在小區1306中，天線群組1324、1326及1328各自對應於一不同扇區。Figure 13 illustrates an exemplary multiple access wireless communication system. The multiple access wireless communication system 1300 includes a plurality of cells, such as cells 1302, 1304, and 1306. In the exemplary system illustrated in FIG. 13, each cell 1302, 1304, and 1306 can include an access point 1350 that includes a plurality of sectors. Multiple sectors are formed by a number of antenna groups each responsible for communicating with an access terminal in one of the cells. In cell 1302, antenna groups 1312, 1314, and 1316 each correspond to a different sector. In cell 1304, antenna groups 1318, 1320, and 1322 each correspond to a different sector. In cell 1306, antenna groups 1324, 1326, and 1328 each correspond to a different sector.

每一小區包括與每一存取網路之一或多個扇區通訊之若干存取終端機。舉例而言，存取終端機1330及1332與存取點(或基地台)1342通訊，存取終端機1334及1336與存取網路1344通訊，且存取終端機1338及1340與存取網路1346通訊。Each cell includes a number of access terminals that communicate with one or more sectors of each access network. For example, the access terminals 1330 and 1332 communicate with an access point (or base station) 1342, the access terminals 1334 and 1336 communicate with the access network 1344, and the access terminals 1338 and 1340 and the access network Road 1346 communication.

如圖11中所說明，每一存取終端機1330、1332、1334、1336、1338及1340位於其各別小區之與同一小區中之每一其他存取終端機不同的部分中。另外，每一存取終端機可距其與之通訊之相應天線群組不同之距離。此等兩個因素提供(亦歸因於小區中之環境及其他條件)使得每一存取終端機與其正與之通訊的其相應天線群組之間呈現不同通道條件之情形。As illustrated in Figure 11, each of the access terminals 1330, 1332, 1334, 1336, 1338, and 1340 is located in a different portion of its respective cell from each of the other access terminals in the same cell. In addition, each access terminal can be at a different distance than the corresponding antenna group with which it communicates. These two factors provide (also due to the environment and other conditions in the cell) such that each access terminal presents a different channel condition between its respective antenna group with which it is communicating.

於本文使用時，存取點可為用以與終端機通訊之固定台，且亦可被稱為基地台、節點B或某一其他術語且包括其某些或所有功能性。存取終端機亦可被稱為使用者裝備(UE)、無線通訊設備、終端機、行動台、存取終端機或某一其他術語，且包括其某些或所有功能性。As used herein, an access point may be a fixed station used to communicate with a terminal, and may also be referred to as a base station, a Node B, or some other terminology, and includes some or all of its functionality. An access terminal may also be referred to as a User Equipment (UE), a wireless communication device, a terminal, a mobile station, an access terminal, or some other terminology, and includes some or all of its functionality.

在一實例中，可在基地台處利用一組已知波束用以提供SDMA，例如固定或調適性扇區。若存取網路知曉用於每一使用者之最佳波束，則其可在不同使用者將在不同波束上接收資料之情況下為該等使用者配置同一通道。在另一實例中，系統1300可包括對應於無預編碼之全向波束。存取網路將使用此波束用於廣播或多播傳輸。在又一實例中，系統1300可在此通道資訊被報告至使用者之情況下利用無SDMA之預編碼。In an example, a set of known beams can be utilized at the base station to provide SDMA, such as fixed or adaptive sectors. If the access network knows the best beam for each user, it can configure the same channel for the users if different users will receive the data on different beams. In another example, system 1300 can include an omnidirectional beam corresponding to no precoding. The access network will use this beam for broadcast or multicast transmission. In yet another example, system 1300 can utilize pre-coding without SDMA if this channel information is reported to the user.

此通道資訊可由存取終端機用以計算由存取終端機首選之波束並將此波束指示給存取網路。甚至在無功率配置之情況下，獲知發射器處之通道亦改良(特別是)傳輸天線數目T_M 大於接收天線數目R_M 之系統的容量。藉由沿通道固有向量之方向進行傳輸來獲得容量改良。反饋通道需要額外負擔。This channel information can be used by the access terminal to calculate the beam preferred by the access terminal and direct this beam to the access network. Even in the absence of a power configuration, it is known that the channel at the transmitter improves (especially) the capacity of the system in which the number of transmission antennas T _{M is} greater than the number of receiving antennas R _M . Capacity improvement is achieved by transmitting along the direction of the channel's eigenvectors. The feedback channel requires an extra burden.

SDMA在發射器處提供足夠充足之波束組，此允許排程中之充分靈活性。在經由某種反饋機制被信號傳輸至存取網路之波束上對使用者進行排程。為進行高效排程，發射器應在使用某一波束對每一使用者進行排程之情況下具有對於該使用者之通道品質資訊。SDMA provides sufficient beam sets at the transmitter, which allows for full flexibility in scheduling. The user is scheduled on a beam that is signaled to the access network via some feedback mechanism. For efficient scheduling, the transmitter should have channel quality information for the user if a beam is used to schedule each user.

圖14說明根據本文所提出之各種態樣之多重存取無線通訊系統1400中的發射器及接收器。無線通訊系統1400為簡明起見描繪一個存取網路及一個使用者設備。然而，應瞭解，系統可包括一個以上存取網路及/或一個以上使用者設備，其中額外存取網路及/或使用者設備可大體上類似於或不同於下述例示性存取網路及使用者設備。另外，應瞭解，存取網路及/或使用者設備可使用本文所述之系統及/或方法來促進其間之無線通訊。14 illustrates a transmitter and receiver in a multiple access wireless communication system 1400 in accordance with various aspects set forth herein. The wireless communication system 1400 depicts an access network and a user device for simplicity. However, it should be appreciated that the system can include more than one access network and/or more than one user device, wherein the additional access network and/or user device can be substantially similar or different from the exemplary access network described below. Road and user equipment. In addition, it should be appreciated that the access network and/or user equipment can employ the systems and/or methods described herein to facilitate wireless communication therebetween.

在發射器系統1410處，將若干資料流之訊務資料自包括本發明之態樣之編碼簿之資料源1412提供至一傳輸(TX)資料處理器1414。在某些態樣中，經由各別傳輸天線傳輸每一資料流。TX資料處理器1414基於經選擇用於每一資料流之特定編碼機制而格式化、編碼及交錯該資料流之訊務資料以提供編碼資料。在某些態樣中，TX處理器1414基於使用者(資料流之符號待傳輸至其)及天線(資料流之符號待自其傳輸)而對該等符號應用波束形成權重。在某些態樣中，波束形成權重可基於指示存取網路與存取終端機之間的傳輸路徑之條件的通道回應資訊而產生。通道回應資訊可利用通道品質指示(CQI)資訊或由使用者提供的通道估計而產生。另外，在經排程傳輸的情況下，TX資料處理器1414可基於自使用者傳輸之等級資訊選擇封包格式。At the transmitter system 1410, the traffic data for a number of data streams is provided from a data source 1412 including the codebook of the present invention to a transmission (TX) data processor 1414. In some aspects, each data stream is transmitted via a respective transmit antenna. TX data processor 1414 formats, encodes, and interleaves the traffic data for each data stream based on a particular encoding mechanism selected for each data stream to provide encoded data. In some aspects, TX processor 1414 applies beamforming weights to the symbols based on the user (the symbols of the data stream are to be transmitted thereto) and the antennas (the symbols of the data streams are to be transmitted therefrom). In some aspects, beamforming weights may be generated based on channel response information indicating conditions of a transmission path between the access network and the access terminal. Channel response information can be generated using channel quality indication (CQI) information or channel estimates provided by the user. Additionally, in the case of scheduled transmissions, the TX data processor 1414 can select a packet format based on the level information transmitted from the user.

可使用正交分頻多工(OFDM)技術藉由導頻資料對每一資料流之編碼資料進行多工傳輸。導頻資料通常為以已知方式處理之已知資料模式，且可在接收器系統處用以估計通道回應。接著，基於經選擇以供每一資料流提供調變符號之特定調變機制(例如，BPSK、QSPK、M－PSK或M－QAM)來調變(亦即，符號映射)該資料流之經多工傳輸之導頻及編碼資料。每一資料流之資料速率、編碼及調變可由由處理器1430執行或提供之指令判定。在某些態樣中，並行空間流之數目可根據自使用者傳輸之等級資訊而變化。The coded data of each data stream can be multiplexed by pilot data using orthogonal frequency division multiplexing (OFDM) technology. The pilot data is typically a known data pattern that is processed in a known manner and can be used at the receiver system to estimate channel response. The data stream is then modulated (ie, symbol mapped) based on a particular modulation mechanism (eg, BPSK, QSPK, M-PSK, or M-QAM) selected to provide a modulation symbol for each data stream. Pilot and coded data for multiplex transmission. The data rate, encoding, and modulation of each data stream can be determined by instructions executed or provided by processor 1430. In some aspects, the number of parallel spatial streams may vary based on level information transmitted from the user.

將用於資料流之調變符號提供至一TX MIMO處理器1420，該TX MIMO處理器1420可進一步處理該等調變符號(例如，對於OFDM)。TX MIMO處理器1420將NT個符號流提供至NT個發射器(TMTR)1422a至1422t。在某些態樣中，TX MIMO處理器1420基於使用者(資料流之符號待傳輸至其)及天線(資料流之符號待自彼使用者通道回應資訊而自其傳輸)將波束形成權重應用於該等符號。The modulation symbols for the data stream are provided to a TX MIMO processor 1420, which may further process the modulated symbols (e.g., for OFDM). TX MIMO processor 1420 provides NT symbol streams to NT transmitters (TMTR) 1422a through 1422t. In some aspects, the TX MIMO processor 1420 applies beamforming weights based on the user (the symbol of the data stream is to be transmitted to it) and the antenna from which the symbol of the data stream is to be transmitted from the user channel response information. In these symbols.

每一發射器1422接收並處理各別符號流以提供一或多個類比信號，且進一步調節(例如，放大、濾波及增頻轉換)該等類比信號以提供適合於經由MIMO通道傳輸的經調變信號。分別自NT個天線1424a至1424t傳輸來自發射器1422a至1422t之NT個經調變信號。Each transmitter 1422 receives and processes a respective symbol stream to provide one or more analog signals, and further conditions (e.g., amplifies, filters, and upconverts) the analog signals to provide a modulated tone suitable for transmission over a MIMO channel. Change the signal. NT modulated signals from transmitters 1422a through 1422t are transmitted from NT antennas 1424a through 1424t, respectively.

在接收器系統1450處，所傳輸之經調變信號由NR個天線1452a至1452r接收，且所接收信號自每一天線1452提供至各別接收器(RCVR)1454。每一接收器1454調節(例如，濾波、放大及降頻轉換)各別所接收信號，數位化經調節信號以提供樣本，且進一步處理該等樣本以提供相應"所接收"符號流。At receiver system 1450, the transmitted modulated signals are received by NR antennas 1452a through 1452r, and the received signals are provided from each antenna 1452 to a respective receiver (RCVR) 1454. Each receiver 1454 conditions (eg, filters, amplifies, and downconverts) the respective received signals, digitizes the conditioned signals to provide samples, and further processes the samples to provide a corresponding "received" symbol stream.

一RX資料處理器1460接著基於特定接收器處理技術自NR個接收器1454接收並處理NR個所接收符號流。以下更詳細地描述由RX資料處理器1460所進行之處理。每一偵測得之符號流包括為經傳輸用於相應資料流之調變符號之估計的符號。RX資料處理器1460接著解調變、去交錯及解碼每一偵測得之符號流以恢復資料流之訊務資料。由RX資料處理器1460進行之處理與由發射器系統1410處之TX MIMO處理器1420及TX資料處理器1414所執行之處理互補。An RX data processor 1460 then receives and processes the NR received symbol streams from NR receivers 1454 based on a particular receiver processing technique. The processing by RX data processor 1460 is described in more detail below. Each detected symbol stream includes a symbol that is an estimate of the modulation symbol transmitted for the corresponding data stream. The RX data processor 1460 then demodulates, deinterleaves, and decodes each detected symbol stream to recover the traffic data for the data stream. The processing by RX data processor 1460 is complementary to the processing performed by TX MIMO processor 1420 and TX data processor 1414 at transmitter system 1410.

由RX處理器1460產生之通道回應估計可用於在接收器處執行空間、空間/時間處理，調整功率位準，改變調變速率或機制或其他動作。RX處理器1460可進一步估計偵測得之符號流的信號雜音干擾比(SNR)及可能的其他通道特性，且將此等量提供至一處理器1470。RX資料處理器1460或處理器1470可進一步得到系統之"有效"SNR之估計。處理器1470接著提供可包含關於通訊鏈路及/或所接收資料流之各種類型之資訊的估計通道資訊(CSI)。舉例而言，CSI可僅包含操作SNR及/或等級。CSI接著由一亦自一資料源1416接收用於若干資料流之訊務資料的TX資料處理器1418處理，由一調變器1480調變，由發射器1454a至1454r調節，且被傳輸回至發射器系統1410。Channel response estimates generated by RX processor 1460 can be used to perform spatial, spatial/temporal processing, adjust power levels, change modulation rates or mechanisms or other actions at the receiver. The RX processor 1460 can further estimate the signal to noise interference ratio (SNR) of the detected symbol stream and possibly other channel characteristics, and provide the equal amount to a processor 1470. The RX data processor 1460 or processor 1470 can further derive an estimate of the "effective" SNR of the system. Processor 1470 then provides estimated channel information (CSI) that can contain various types of information about the communication link and/or the received data stream. For example, the CSI may only include operational SNR and/or rank. The CSI is then processed by a TX data processor 1418 that also receives the traffic data for a plurality of data streams from a data source 1416, modulated by a modulator 1480, adjusted by the transmitters 1454a through 1454r, and transmitted back to Transmitter system 1410.

在發射器系統1410處，來自接收器系統1450之經調變信號由天線1424接收，由接收器1422調節，由解調變器1440解調變，且由一RX資料處理器1442處理以恢復由接收器系統報告之CSI。所報告之CSI接著被提供至處理器1430且用以(1)判定待用於資料流之資料速率及編碼及調變機制及(2)產生對用於TX資料處理器1414及TX MIMO處理器1420之各種控制。At transmitter system 1410, the modulated signal from receiver system 1450 is received by antenna 1424, adjusted by receiver 1422, demodulated by demodulation transformer 1440, and processed by an RX data processor 1442 to recover The CSI reported by the receiver system. The reported CSI is then provided to the processor 1430 and used to (1) determine the data rate and coding and modulation mechanism to be used for the data stream and (2) generate the pair for the TX data processor 1414 and the TX MIMO processor. Various controls of the 1420.

在接收器處，各種處理技術可用以處理NR個所接收信號以偵測NT個所傳輸符號流。可將此等接收器處理技術分組為兩個基本類別：(i)空間及空間時間接收器處理技術(其亦被稱為均衡技術)；及(ii)"連續歸零/均衡及干擾消除"接收器處理技術(其亦被稱為"連續干擾消除"或"連續消除"接收器處理技術)。At the receiver, various processing techniques can be used to process the NR received signals to detect the NT transmitted symbol streams. These receiver processing techniques can be grouped into two basic categories: (i) spatial and spatial time receiver processing techniques (also referred to as equalization techniques); and (ii) "continuous zeroing/equalization and interference cancellation" Receiver processing techniques (also known as "continuous interference cancellation" or "continuous cancellation" receiver processing techniques).

由NT個傳輸天線及NR個接收天線形成之MIMO通道可分解為N_S 個獨立通道，其中N _S min{N _T ,N _R }。N_S 個獨立通道中之每一者亦可被稱為MIMO通道之空間子通道(或傳輸通道)且對應於一維度。A MIMO channel formed by NT transmit antennas and NR receive antennas can be decomposed into N _S independent channels, where N _S Min{ N _T , N _R }. Each of the N _S independent channels may also be referred to as a spatial sub-channel (or transmission channel) of the MIMO channel and corresponds to a dimension.
