Description
本發明屬於通信技術領域,具體來說,是關於一種通道狀態資訊測量方法以及裝置。 The invention belongs to the field of communication technologies, and in particular relates to a channel state information measuring method and device.
鑒於多入多出(Multiple Input Multiple Output,MIMO)技術對於提高峰值速率與系統頻譜利用率的重要作用,現有的長期演進(Long Term Evolution,LTE)/長期演進增強(LTE-Advanced,LTE-A)等無線接入技術都是以MIMO+正交頻分複用(Orthogonal Frequency Division Multiplexing,OFDM)技術為基礎構建起來的。此外,由於MIMO技術的性能增益來自於多天線系統所能獲得的空間自由度,因此,MIMO技術在標準化發展過程中的一個重要的演進方向便是維度的擴展。 In view of the important role of Multiple Input Multiple Output (MIMO) technology in improving peak rate and system spectrum utilization, the existing Long Term Evolution (LTE)/Long Term Evolution (LTE-Advanced, LTE-A) The radio access technologies are all based on MIMO + Orthogonal Frequency Division Multiplexing (OFDM) technology. In addition, since the performance gain of MIMO technology comes from the spatial freedom that multi-antenna systems can obtain, an important evolution direction of MIMO technology in the development of standardization is the expansion of dimensions.
在採用傳統的無源天線系統(Passive Antenna System,PAS)結構的基地台天線系統中,多個天線埠(每個埠對應著獨立的射頻-中頻-基帶通道)水準排列,其中,每個埠對應的垂直維度上的多個陣子之間由射頻電纜連線,因此,現有的MIMO技術只能在水準維度上通過對不同埠間的相對幅度/相位的調整實現對各個埠信號在水準維度空間特性的優化,在垂直維度則只能採用統一的磁區級賦形。而在移動通信系統中引入有源 天線系統(Active Antenna System,AAS)技術之後,基地台天線系統才能夠在垂直維度獲得更大的自由度,才能夠在三維空間實現對使用者終端(User Equipment,UE)級的信號優化。 In a base station antenna system using a conventional Passive Antenna System (PAS) structure, a plurality of antennas (each corresponding to an independent RF-IF-baseband channel) are horizontally arranged, wherein each多个 The corresponding vertical dimension is connected by RF cable. Therefore, the existing MIMO technology can only achieve the horizontal dimension of each chirp by adjusting the relative amplitude/phase of different turns in the horizontal dimension. The optimization of the spatial characteristics can only be achieved by a uniform magnetic domain level in the vertical dimension. And introducing active in mobile communication systems After the Antenna System (AAS) technology, the base station antenna system can obtain greater degrees of freedom in the vertical dimension to achieve signal optimization at the User Equipment (UE) level in three dimensions.
基於上述情況,產業界正在進一步地將MIMO技術向著三維化和大規模化的方向推進。目前,3GPP正在開展3D通道建模的研究專案,其後預計還將繼續開展8個無線埠及以下的仰角波束賦形(Elevation Beamforming,EBF)與超過8個埠(如16、32或64)的全維多入多出(Full Dimension MIMO,FD-MIMO)技術研究與標準化工作。而學術界則更為前瞻地開展了針對基於更大規模天線陣列(包含一百或數百根,甚至更多陣子)的MIMO技術的研究與測試工作。學術研究與初步的通道實測結果表明,massive MIMO(大規模多入多出)技術將能夠極大地提升系統頻帶利用效率,支援更大數量的接入用戶。因此,各大研究組織均將massive MIMO技術視為下一代移動通信系統中最有潛力的實體層技術之一。 Based on the above situation, the industry is further advancing MIMO technology in the direction of three-dimensionalization and large-scale. At present, 3GPP is carrying out research projects on 3D channel modeling, and it is expected to continue to carry out 8 Elevation Beamforming (EBF) and more than 8 埠 (such as 16, 32 or 64). Research and standardization of Full Dimension MIMO (FD-MIMO) technology. The academic community is more forward-looking in research and testing of MIMO technology based on larger antenna arrays (containing one hundred or hundreds, or even more). Academic research and preliminary channel measurement results show that massive MIMO (large-scale multi-input and multi-out) technology will greatly improve system bandwidth utilization efficiency and support a larger number of access users. Therefore, major research organizations regard massive MIMO technology as one of the most promising physical layer technologies in next-generation mobile communication systems.
然而,在MIMO技術中,尤其是對多用戶多入多出(Multi-User MIMO,MU-MIMO)技術而言,網路側能夠獲得的通道狀態資訊精度將直接決定預編碼/波束賦形的精度與調度演算法的效能,從而影響到整體系統性能,因此,通道狀態資訊的獲取一直都是MIMO技術標準化中最核心的問題之一。而對於頻分雙工(Frequency Division Duplexing,FDD)系統而言,由於上下行鏈路之間存在較大的頻率間隔,一般很難直接通過上行通道的測量獲取下行通道狀態資訊,所以現有的FDD系統一般採用基於下行參考信號測量並回饋通道狀態資訊(Channel State Information,CSI)的機制。在這種情況下,通道狀態資訊的空間解析度直接取決於參考 信號的埠數量。當天線陣列規模很大時,如果為了保證下行而引入新的參考信號埠,將會帶來顯著的時頻資源開銷。但是如果限制參考信號埠數,又不能保證下行通道狀態資訊測量的空間解析度,從而無法發揮massive MIMO的性能優勢。而如果沿用多CSI進程的機制,在每個進程中通過該進程所對應的通道狀態資訊參考信號(Channel State Information Reference Signal,CSI-RS)埠分別對特定天線埠進行通道估計,雖然可以實現3D通道測量。但是,基於CSI-RS的多CSI進程同樣會增加參考信號開銷。 However, in MIMO technology, especially for multi-user MIMO (MU-MIMO) technology, the channel state information accuracy that can be obtained by the network side directly determines the accuracy of precoding/beamforming. The performance of the scheduling algorithm affects the overall system performance. Therefore, the acquisition of channel state information has always been one of the core issues in the standardization of MIMO technology. For the Frequency Division Duplexing (FDD) system, because there is a large frequency interval between the uplink and downlink, it is generally difficult to obtain the downlink channel status information directly through the measurement of the uplink channel, so the existing FDD is available. The system generally adopts a mechanism for measuring and feeding back Channel State Information (CSI) based on a downlink reference signal. In this case, the spatial resolution of the channel status information is directly dependent on the reference. The number of signals. When the size of the antenna array is large, if a new reference signal is introduced to ensure downlink, significant time-frequency resource overhead will be incurred. However, if the reference signal is limited, the spatial resolution of the downlink channel state information measurement cannot be guaranteed, and the performance advantage of massive MIMO cannot be exerted. If the mechanism of the multi-CSI process is used, the channel state information reference signal (CSI-RS) corresponding to the process is used in each process to perform channel estimation on a specific antenna, although 3D can be implemented. Channel measurement. However, CSI-RS based multi-CSI processes will also increase the reference signal overhead.
針對上述技術中,無論是引入新的參考信號埠,還是沿用基於CSI-RS的多CSI進程都將不可避免地增加參考信號的開銷,目前尚未提出有效的解決方案。 In view of the above techniques, whether to introduce a new reference signal or to use a CSI-RS based multi-CSI process will inevitably increase the overhead of the reference signal, and no effective solution has been proposed yet.

為了方便理解本發明的上述技術方案,下面將從CSI測量方式、CSI上報方式以及CSI的計算與回饋三個方面對本發明的上述技術方案進行詳細說明。 In order to facilitate the understanding of the above technical solutions of the present invention, the above technical solutions of the present invention will be described in detail from three aspects of CSI measurement mode, CSI reporting mode, and CSI calculation and feedback.
在LTE/LTE-A系統中,包括業務通道物理下行共用通道(Physical Downlink Shared Channel,PDSCH)的傳輸方式(Transmission Mode,TM)1-7、傳輸L1/2(Layer1/2)控制資訊的物理下行鏈路控制通道(Physical Downlink Control Channel,PDCCH)以及傳輸廣播資訊的物理廣播通道(Physical Broadcast Channel,PBCH)都採用了基於CRS的傳輸與通道狀態資訊測量機制。儘管在LTE/LTE-A系統發展過程中,隨著參考信號的測量與傳輸功能的分離,CRS在新引入的PDSCH TM8-10中正逐漸地被CSI-RS與UE專屬參考信號(UE-specific Reference Signal,URS)取代,但是無論從相容性上,還是從控制與廣播資訊的傳輸角度出發,在LTE 的後續演進版本中CRS仍然是不可缺少的,但是目前定義的多CSI進程的測量與回饋機制中,只能利用CSI-RS而無法使用CRS這種每個子幀內都必須傳輸的參考信號,因此,需要重新定義多CSI進程的測量與回饋機制。 In the LTE/LTE-A system, the physical mode includes a Physical Downlink Shared Channel (PDSCH) transmission mode (Transmission Mode, TM) 1-7, and a L1/2 (Layer 1/2) control information physics. The Physical Downlink Control Channel (PDCCH) and the Physical Broadcast Channel (PBCH) that transmit broadcast information use CRS-based transmission and channel state information measurement mechanisms. Although in the development of the LTE/LTE-A system, with the separation of the measurement and transmission functions of the reference signal, the CRS is gradually being used by the CSI-RS and the UE-specific reference signal in the newly introduced PDSCH TM8-10 (UE-specific Reference) Signal, URS), but in terms of compatibility, or from the perspective of control and broadcast information transmission, in LTE The CRS is still indispensable in the subsequent evolution version, but the measurement and feedback mechanism of the currently defined multi-CSI process can only use the CSI-RS and cannot use the reference signal that must be transmitted in each subframe of the CRS. It is necessary to redefine the measurement and feedback mechanism of multiple CSI processes.
在本發明的上述技術方案中,本發明不僅重新定義了CSI的測量方式,同時還重新定義了CSI的上報方式以及CSI的計算與回饋機制,具體的情況如下:對於CSI測量方式來說,本發明定義了兩種測量方式,其中,一種是通過網路側向終端配置多個CSI進程,每個CSI進程對應於一個參考信號資源,並且,多個CSI進程中,可以有至少一個CSI進程被配置為基於CRS進行測量,而對於被配置為基於CRS進程測量的CSI進程,其CRS埠數量與PBCH使用的CRS埠數保持一致;另一種是通過網路側發送單獨的控制資訊通知終端基於CRS進行通道狀態資訊測量,並通過網路側向終端配置多個CSI進程,每個CSI進程對應於一個CSI-RS參考信號資源。 In the above technical solution of the present invention, the present invention not only redefines the measurement mode of the CSI, but also redefines the CSI reporting mode and the CSI calculation and feedback mechanism. The specific situation is as follows: For the CSI measurement mode, The present invention defines two measurement modes, one of which is to configure multiple CSI processes through a network side terminal, each CSI process corresponds to one reference signal resource, and in a plurality of CSI processes, at least one CSI process may be It is configured to perform measurement based on CRS, and for the CSI process configured to be measured based on the CRS process, the number of CRS埠 is consistent with the number of CRS parameters used by the PBCH; the other is to send a separate control information through the network side to notify the terminal to perform based on the CRS. The channel status information is measured, and multiple CSI processes are configured through the network side terminal, and each CSI process corresponds to one CSI-RS reference signal resource.
上述兩種測量方式中的參考信號資源包括參考信號的類型、參考信號的埠數量、參考信號的序列、參考信號的圖樣等資訊。 The reference signal resources in the above two measurement methods include information such as the type of the reference signal, the number of reference signals, the sequence of the reference signal, and the pattern of the reference signal.
而對於CSI上報方式,本發明通過網路側向終端約定如果基於CRS和基於CSI-RS的上報發生衝突,則按照預先設定的優先順序別選擇性地丟棄某些上報資訊,同時通過網路側向終端配置上報CSI的類型(如子帶、寬頻、預編碼矩陣指示(Precoding Matrix Indication,PMI)或non-PMI等)以及上報的起始時刻與週期,促使終端根據該類型以及起始時刻與週期上報CSI等。 For the CSI reporting mode, the present invention appoints through the network side terminal that if the CRS and the CSI-RS-based reporting conflicts, the certain reporting information is selectively discarded according to a preset priority order, and the network is simultaneously discarded. The roadside terminal is configured to report the type of CSI (such as subband, broadband, Precoding Matrix Indication (PMI), or non-PMI, etc.) and the reported start time and period, so that the terminal can start according to the type. The CSI and so on are reported at the beginning and the time.
而對於CSI的計算與回饋機制,本發明利用終端向網路側配置的CSI測量方式進行測量,同時計算CSI,而計算CSI的具體方式則可以分為三種,其中,一種是獨立計算和回饋,具體地,對於計算而言,可以根據對每個CSI進程所對應的參考信號的測量分別計算CSI(主要針對第一種測量方式),還可以根據每個CSI進程所對應的CSI-RS的測量分別計算CSI,同時根據對CRS的測量計算CSI(主要針對第二種測量方式);而對於回饋而言,則可以選擇全部的CSI進行回饋,也可以根據實際的需求,選擇局部執行緒的CSI進行回饋。另一種是統一計算和回饋,具體地,根據對所有可用的參考信號資源的測量得到統一的CSI(可能包含秩指示(Rank Indication,PMI/RI)/通道品質指示符(Channel Quality Indicator,CQI)全部或部分資訊的組合),並回饋該CSI。 For the CSI calculation and feedback mechanism, the present invention utilizes the CSI measurement mode configured by the terminal to the network side to perform measurement, and simultaneously calculates the CSI, and the specific manner of calculating the CSI can be divided into three types, one of which is independent calculation and feedback, and the specific For calculation, the CSI may be separately calculated according to the measurement of the reference signal corresponding to each CSI process (mainly for the first measurement mode), and may also be separately measured according to the CSI-RS corresponding to each CSI process. The CSI is calculated, and the CSI is calculated according to the measurement of the CRS (mainly for the second measurement mode); for the feedback, all the CSIs can be selected for feedback, or the CSI of the local thread can be selected according to actual requirements. Give feedback. The other is unified computing and feedback. Specifically, unified CSI is obtained according to the measurement of all available reference signal resources (possibly including Rank Indication (PMI/RI)/Channel Quality Indicator (CQI).
