Description

一種解調參考信號(DMRS)埠的傳輸配置指示方法、網路設備、通信裝置及電腦可讀存儲介質 Transmission configuration instruction method of demodulation reference signal (DMRS) port, network equipment, communication device and computer readable storage medium

本發明屬於無線通訊技術領域，特別是關於一種解調參考信號(demodulation reference signal，DMRS)埠的傳輸配置指示方法、網路設備、通信裝置及電腦可讀存儲介質。 The present invention belongs to the field of wireless communication technology, and particularly relates to a method for indicating a transmission configuration of a demodulation reference signal (DMRS) port, a network device, a communication device, and a computer-readable storage medium.

在新空中介面(New Radio，NR)系統中，採用多點協作傳輸能夠改善小區邊緣的覆蓋，在服務區內提供更為均衡的服務品質。隨著頻段的升高，從保證網路覆蓋的角度出發，需要相對密集的存取點部署。 In the New Radio (NR) system, the use of coordinated multipoint transmission can improve the coverage at the edge of the cell and provide a more balanced quality of service in the service area. With the increase of frequency bands, from the perspective of ensuring network coverage, relatively dense deployment of access points is required.

在高頻段，目前的趨勢是採用模組化的有源天線陣列。有源電線的每個傳輸接收點(transmission reception point，TRP)的天線陣可以被分為若干相對獨立的天線面板，因此整個陣面的形態和埠數都可以隨部署場景與應用需求進行靈活的調整。TRP或天線面板之間也可以由光纖連接，進行更為靈活的分散式部署。在毫米波波段，隨著波長的減小，人體或車輛等障礙物所產生的阻擋效應將更為顯著。這種情況下，利用多個TRP或天線面板之間的協作，從多個角度的多個波束進行傳輸或接收，從而降低阻擋效應帶來的不利影響。 In the high frequency band, the current trend is to use modular active antenna arrays. The antenna array of each transmission reception point (TRP) of the active wire can be divided into several relatively independent antenna panels, so the shape and number of ports of the entire array can be flexibly adapted to the deployment scenarios and application requirements adjust. TRP or antenna panels can also be connected by optical fiber for more flexible distributed deployment. In the millimeter wave band, as the wavelength decreases, the blocking effect generated by obstacles such as human bodies or vehicles will be more significant. In this case, the cooperation between multiple TRPs or antenna panels is used to transmit or receive multiple beams from multiple angles, thereby reducing the adverse effects of blocking effects.

根據發送信號流到多個TRP或天線面板的映射關係，多點協作傳輸技術可以分為相干和非相干傳輸兩種。其中，非相干傳輸時，每個資料流程只映射到部分TRP或天線面板上。相較於相干傳輸，非相干傳輸對於傳輸點之間的同步以及回程鏈路的傳輸能力要求較低，對現實部署條件中的很多非理想因素不敏感，因此是多點傳輸技術的重點考慮方案。目前Rel-16中正在進行非相干聯合傳輸(non-coherent joint transmission，NC-JT)技術的研究。 According to the mapping relationship of the transmitted signal stream to multiple TRPs or antenna panels, the coordinated multi-point transmission technology can be divided into two types: coherent and non-coherent transmission. Among them, in the case of incoherent transmission, each The data flow is only mapped to part of the TRP or antenna panel. Compared with coherent transmission, non-coherent transmission requires less synchronization between transmission points and the transmission capability of the backhaul link, and is insensitive to many non-ideal factors in actual deployment conditions, so it is a key consideration for multipoint transmission technology. . Currently, Rel-16 is conducting research on non-coherent joint transmission (NC-JT) technology.

NC-JT傳輸可以採用單實體下行控制通道(physical downlink control channel，PDCCH)調度單個實體下行共用通道(physical downlink shared channel，PDSCH)的方式(稱為single-PDCCH方式)，或採用多個PDCCH各自調度對應的PDSCH的方式(稱為multi-PDCCH方式)。 NC-JT transmission can use a single entity downlink control channel (physical downlink control channel, PDCCH) to schedule a single entity downlink shared channel (physical downlink shared channel, PDSCH) mode (called single-PDCCH mode), or use multiple PDCCHs each The method of scheduling the corresponding PDSCH (referred to as the multi-PDCCH method).

對於single-PDCCH方式，需要根據準同位(Quasi Co-Loacted，QCL)關係對DMRS埠進行碼分複用(code division multiplexing，CDM)分組，同一DMRS CDM組中的DMRS埠之間是QCL的，即通過不同的DMRS CDM組來指示不同的QCL資訊。網路側系統通過控制信令將DMRS埠的傳輸配置指示資訊發送給終端。 For single-PDCCH mode, DMRS ports need to be grouped by code division multiplexing (CDM) according to the Quasi Co-Loacted (QCL) relationship. The DMRS ports in the same DMRS CDM group are QCL. That is, different DMRS CDM groups are used to indicate different QCL information. The network side system sends the transmission configuration instruction information of the DMRS port to the terminal through control signaling.

對於需要支援從多個非QCL的TRP或天線面板同時向終端發送不同資料流程的NC-JT傳輸，當秩(rank)大於或等於2時，為終端分配的DMRS埠應屬於至少兩個DMRS CDM組。但是，目前的DMRS埠的傳輸配置指示方法不能很好地支援上述需求。 For NC-JT transmission that needs to support multiple non-QCL TRPs or antenna panels to send different data processes to the terminal at the same time, when the rank (rank) is greater than or equal to 2, the DMRS ports allocated for the terminal should belong to at least two DMRS CDMs Group. However, the current transmission configuration indication method of the DMRS port cannot well support the above requirements.

Table 4: DMRS port allocation mode (Antenna port(s)(1000+DMRS port), dmrs-Type=2, maxLength=2) when at most 2 pre-DMRS symbols are configured under DMRS type 2.

上述表1-表4中，網路設備為終端分配DMRS埠後，向終端發送對應的DMRS埠分配資訊，從而可以向終端指示DMRS埠的傳輸配置。其中，DMRS埠分配資訊包括表1-表4中「value」的取值。 In the above Table 1 to Table 4, after the network device allocates the DMRS port to the terminal, it sends the corresponding DMRS port allocation information to the terminal, so as to indicate the transmission configuration of the DMRS port to the terminal. Among them, the DMRS port allocation information includes the values of "value" in Table 1 to Table 4.

例如，在採用DMRS類型1且僅配置1個前置DMRS符號的情況下，若基地台為終端分配DMRS埠0和DMRS埠2，並配置了2個DMRS CDM組(根據TS38.212中的規定，DMRS埠0和DMRS埠1分別屬於不同的DMRS CDM組)，則基地台向終端發送下行控制資訊(downlink control information，DCI)，該DCI中包括DMRS埠分配資訊，根據表1，該DMRS埠分配資訊的取值為11。終端根據接收到的DMRS埠分配資訊可以得知基地台為其分配的DMRS埠0和DMRS埠2，並確定DMRS埠0和DMRS埠2不是準同位(QCL)的。 For example, when DMRS type 1 is used and only one pre-DMRS symbol is configured, if the base station allocates DMRS port 0 and DMRS port 2 to the terminal, and configures 2 DMRS CDM groups (according to the regulations in TS38.212 DMRS port 0 and DMRS port 1 belong to different DMRS CDM groups), the base station sends downlink control information to the terminal (downlink control information, DCI), the DCI includes DMRS port allocation information. According to Table 1, the value of the DMRS port allocation information is 11. According to the received DMRS port allocation information, the terminal can know the DMRS port 0 and DMRS port 2 allocated by the base station, and determine that the DMRS port 0 and DMRS port 2 are not quasi-coordinated (QCL).

再例如，在採用DMRS類型2且配置2個前置DMRS符號的情況下，若基地台為終端分配DMRS埠0和DMRS埠1，並配置了3個DMRS CDM組(根據TS38.212中的規定，DMRS埠0和DMRS埠1屬於同一DMRS CDM組)，則基地台向終端發送DCI，該DCI中包括DMRS埠分配資訊，根據表4，該DMRS埠配置資訊的取值為17。終端根據接收到的DMRS埠配置資訊可以得知基地台為其分配的DMRS埠0和DMRS埠1，並確定DMRS埠0和DMRS埠1是準同位(QCL)的。 For another example, when DMRS type 2 is used and two pre-DMRS symbols are configured, if the base station allocates DMRS port 0 and DMRS port 1 to the terminal, and configures 3 DMRS CDM groups (according to the regulations in TS38.212 , DMRS port 0 and DMRS port 1 belong to the same DMRS CDM group), the base station sends DCI to the terminal. The DCI includes DMRS port allocation information. According to Table 4, the value of the DMRS port configuration information is 17. The terminal can know the DMRS port 0 and DMRS port 1 allocated by the base station according to the received DMRS port configuration information, and determine that the DMRS port 0 and DMRS port 1 are quasi-coordinated (QCL).

本發明實施例中，同一DMRS CDM組中的DMRS埠之間是QCL的，不同DMRS CDM組的DMRS埠之間可能是QCL的也可能不是QCL的。其中，QCL是指某個天線埠上的符號所經歷的通道的大尺度參數可以從另一個天線埠上的符號所經歷的通道推斷出來。其中的大尺度參數可以包括時延擴展、平均時延、都卜勒擴展、都卜勒偏移、平均增益以及空間接收參數等。 In the embodiment of the present invention, the DMRS ports in the same DMRS CDM group are QCL, and the DMRS ports of different DMRS CDM groups may be QCL or not QCL. Among them, QCL means that the large-scale parameters of the channel experienced by the symbol on a certain antenna port can be inferred from the channel experienced by the symbol on another antenna port. The large-scale parameters can include delay spread, average delay, Doppler spread, Doppler offset, average gain, and spatial reception parameters.

多點傳輸過程中涉及到的多個TRP或天線面板可能對應於多個地理位置不同的TRP或天線面板朝向有差異的多個磁區。例如，當終端從不同的TRP或天線面板接收資料時，各個TRP或天線面板在空間上的差異會導致來自不同TRP或天線面板的接收鏈路的大尺度通道參數的差別，如都卜勒頻偏、時延擴展等。通道的大尺度參數直接影響通道估計時濾波器係數的調整與優化，對應於不同TRP或天線面板發出的信號，應當使用不同的通道估計濾波參數以適應相應的通道傳播特性。因此，儘管各個TRP或天線面板在空間位置或角度上的差異對於終端以及多點傳輸操作本身而言是透明的，但是上述空間差異對於通道大尺度參數的影響則是終端進行通道估計與接收檢測時需要考慮的重要因素。 The multiple TRPs or antenna panels involved in the multipoint transmission process may correspond to multiple TRPs or antenna panels with different geographical locations and multiple magnetic regions with different orientations. For example, when the terminal receives data from different TRPs or antenna panels, the spatial difference of each TRP or antenna panel will result in the difference of large-scale channel parameters of receiving links from different TRPs or antenna panels, such as Doppler frequency. Deviation, delay extension, etc. The large-scale parameters of the channel directly affect the filter system when the channel is estimated. The adjustment and optimization of the number corresponds to the signals emitted by different TRPs or antenna panels, and different channel estimation filtering parameters should be used to adapt to the corresponding channel propagation characteristics. Therefore, although the difference in the spatial position or angle of each TRP or antenna panel is transparent to the terminal and the multipoint transmission operation itself, the influence of the above spatial difference on the large-scale parameters of the channel is that the terminal performs channel estimation and reception detection. Important factors that need to be considered.

所謂兩個天線埠在某些大尺度參數意義下QCL，是指這兩個天線埠的這些大尺度參數是相同的。或者說，只要兩個埠的某些大尺度參數一致，不論它們的實際實體位置或對應的天線面板朝向是否存在差異，終端可以認為這兩個天線埠是發自相同的位置(即准共站址)。 The so-called QCL of the two antenna ports in the sense of some large-scale parameters means that these large-scale parameters of the two antenna ports are the same. In other words, as long as some large-scale parameters of the two ports are the same, regardless of whether their actual physical positions or the corresponding antenna panel orientations are different, the terminal can think that the two antenna ports are sent from the same location (i.e., quasi co-site site).

針對一些典型的應用場景，考慮到各種參考信號之間可能的QCL關係，從簡化信令的角度出發，NR系統中將幾種通道大尺度參數分為以下4個類型，對應於4個QCL類型，以便於系統根據不同場景進行配置或指示：QCL類型A(QCL-TypeA)：該類型的QCL涉及的參數包括：{都卜勒(doppler)頻移，Doppler增寬，平均時延，時延擴展}。除了空間接收參數之外的其他大尺度參數均相同。對於6GHz以下頻段而言，可能並不需要空間接收參數。 For some typical application scenarios, considering the possible QCL relationship between various reference signals, from the perspective of simplifying signaling, the NR system divides several channel large-scale parameters into the following 4 types, corresponding to the 4 QCL types , So that the system can be configured or instructed according to different scenarios: QCL Type A (QCL-TypeA): The parameters involved in this type of QCL include: {Doppler frequency shift, Doppler broadening, average delay, delay Extension}. Except for the spatial reception parameters, other large-scale parameters are the same. For frequency bands below 6 GHz, spatial reception parameters may not be needed.

QCL類型B(QCL-TypeB)：該類型的QCL所涉及的參數包括：{Doppler頻移，Doppler增寬}。僅針對6GHz以下頻段的如下兩種情況。 QCL Type B (QCL-TypeB): The parameters involved in this type of QCL include: {Doppler frequency shift, Doppler widening}. Only for the following two situations in the frequency band below 6GHz.

情況1：使用窄波束的參考信號時，可以寬波束參考信號為QCL參考時。例如時頻跟蹤參考信號(tracking reference signal，TRS)一般會以磁區級的寬波束發送，通道狀態資訊參考信號(chanel state information-reference signals，CSI-RS)可能採用窄波束發送。在這種情況下，一般認為從同一個網站(如TRP或天線面板)發出的信號所經歷的都卜勒參數仍然是近似一致的。但是，不同寬度的波束所覆蓋的散射體是不同的，因此會對信號傳播所經歷的時延擴展和平均時延參量帶來較為明顯的影響。在這種情況下，不能假設CSI-RS和TRS在時延擴展和平均時延參數意義下QCL。 Case 1: When a narrow-beam reference signal is used, the wide-beam reference signal can be a QCL reference. For example, the time-frequency tracking reference signal (TRS) is generally transmitted with a magnetic zone-level wide beam, and the channel state information-reference signals (CSI-RS) may be transmitted with a narrow beam. In this case, it is generally considered The Doppler parameters experienced by signals sent from the same website (such as TRP or antenna panels) are still approximately the same. However, the scatterers covered by beams of different widths are different, which will have a more obvious impact on the delay spread and average delay parameters experienced by signal propagation. In this case, it cannot be assumed that CSI-RS and TRS are QCL in the sense of delay spread and average delay parameters.

情況2：目標參考信號的時域密度不足，但頻域密度足夠。例如以TRS作為CSI-RS的QCL參考時，由於CSI-RS的時域密度取決於配置，可能不足以準確估計通道的都卜勒參數，因此都卜勒參數可以從與之QCL的TRS獲取。另外一方面，CSI-RS的頻域密度對於估計平均時延和時延擴展等頻域參數而言是足夠的，因此可以從CSI-RS自身獲取這些參數。 Case 2: The time domain density of the target reference signal is insufficient, but the frequency domain density is sufficient. For example, when the TRS is used as the QCL reference of the CSI-RS, since the time domain density of the CSI-RS depends on the configuration, it may not be sufficient to accurately estimate the Doppler parameters of the channel, so the Doppler parameters can be obtained from the TRS of the QCL. On the other hand, the frequency domain density of the CSI-RS is sufficient for estimating frequency domain parameters such as average delay and delay spread, so these parameters can be obtained from the CSI-RS itself.

QCL類型C(QCL-TypeC)：該類型的QCL涉及的參數包括：{Doppler頻移，平均時延}。僅針對6GHz以上頻段以同步區塊(synchronization singal block，SSB)作為QCL參考的情況。由於SSB佔用的資源和密度有限，一般假設從SSB只能獲得一些較為粗略的大尺度資訊，即都卜勒偏移和平均時延，而其他大尺度參數則需要從目標參考信號自身獲得。 QCL Type C (QCL-TypeC): The parameters involved in this type of QCL include: {Doppler frequency shift, average delay}. Only for the frequency band above 6GHz with synchronization singal block (SSB) as the QCL reference. Due to the limited resources and density occupied by the SSB, it is generally assumed that only some rough large-scale information can be obtained from the SSB, that is, Doppler offset and average delay, while other large-scale parameters need to be obtained from the target reference signal itself.

QCL類型D(QCL-TypeD)：該類型的QCL涉及的參數包括：{空間接收參數}。如前該，由於這一參數主要針對6GHz以上頻段，因此將其單獨作為一個QCL類型。 QCL type D (QCL-TypeD): The parameters involved in this type of QCL include: {spatial receiving parameters}. As mentioned before, since this parameter is mainly for the frequency band above 6GHz, it is regarded as a QCL type alone.

Therefore, the scale and configuration of the attached drawings should not be used. The interpretation of the relationship and limitation of the scope of rights of the present invention in actual implementation shall be explained first.

參見圖3，為本發明實施例提供的在網路設備側實現的DMRS埠的傳輸配置指示流程示意圖，該流程可包括：S301：網路設備為終端配置至少2個DMRS埠，該至少2個DMRS埠屬於至少2個DMRS CDM組；其中，該至少2個DMRS埠對應的DMRS通過至少1個前置DMRS符號傳輸；S302：網路設備向終端發送DCI，該DCI包括DMRS埠分配資訊，該DMRS埠分配資訊用於指示該至少2個DMRS埠的索引、前置DMRS符號的數量，以及DMRS CDM組的數量；其中，該DMRS埠分配資訊可以是本發明實施例中，基於TS38.212中的DMRS埠分配方式所新定義的DMRS埠分配資訊。 Refer to Figure 3, which is a schematic diagram of a DMRS port transmission configuration instruction process implemented on the network device side according to an embodiment of the present invention. The process may include: S301: The network device configures at least two DMRS ports for the terminal, the at least two DMRS ports belong to at least two DMRS CDM groups; among them, the DMRS corresponding to the at least two DMRS ports is transmitted through at least one pre-DMRS symbol; S302: the network device sends DCI to the terminal, and the DCI includes DMRS port allocation information. The DMRS port allocation information is used to indicate the index of the at least two DMRS ports, the number of pre-DMRS symbols, and the number of DMRS CDM groups; wherein, the DMRS port allocation information may be based on the TS38.212 in the embodiment of the present invention. DMRS port allocation information newly defined by the DMRS port allocation method.

基於圖3所示的流程，並結合圖1a所示的DMRS資源示意圖，在採用DMRS類型1並配置了最多1個前置DMRS符號的情況下，如果網路設備為終端分配2個DMRS埠且該2個DMRS埠屬於不同的2個DMRS CDM組，例如，這2個DMRS埠分別為{DMRS埠0，DMRS埠3}或{DMRS埠1，DMRS埠2}或{DMRS埠1，DMRS埠3}，則表1中沒有相應的value值可以指示上述分配情況，因此需要對表1進行擴展，也即需要定義新的DMRS埠分配資訊(即value)，例如針對分配的{DMRS埠0，DMRS埠3}定義value A，針對分配的{DMRS埠1，DMRS埠2}定義value B，針對分配的{DMRS埠1，DMRS埠3}定義value C。其中，value A、value B、value C的取值可以是表1中預留value取值區間內的值。 Based on the process shown in Figure 3 and combined with the DMRS resource diagram shown in Figure 1a, when DMRS type 1 is used and a maximum of 1 pre-DMRS symbol is configured, if the network equipment allocates 2 DMRS ports for the terminal and The 2 DMRS ports belong to different 2 DMRS CDM groups, for example, the 2 DMRS ports are {DMRS port 0, DMRS port 3} or {DMRS port 1, DMRS port 2} or {DMRS port 1, DMRS port 3}, there is no corresponding value in Table 1 that can indicate the above allocation, so Table 1 needs to be extended, that is, new DMRS port allocation information (ie value) needs to be defined, for example, for the allocated {DMRS port 0, DMRS port 3} defines value A, defines value B for allocated {DMRS port 1, DMRS port 2}, and defines value C for allocated {DMRS port 1, DMRS port 3}. Among them, the values of value A, value B, and value C may be values in the reserved value range in Table 1.

需要說明的是，針對上述三種value值以及對應的DMRS埠分配情況，可針對其中的至少一種情況進行擴展。例如，可以在表1中增加value=12，對應的DMRS埠的索引為(1，3)，對應的不包含資料的DMRS CDM組的數量為2。 It should be noted that for the above three value values and the corresponding DMRS port The allocation situation can be expanded for at least one of the situations. For example, you can add value=12 to Table 1, the index of the corresponding DMRS port is (1, 3), and the number of corresponding DMRS CDM groups that do not contain data is 2.

還需要說明的是，在採用DMRS類型1並配置了1個前置DMRS符號的情況下，若網路設備需要為終端配置2個DMRS埠且該2個DMRS埠屬於不同的DMRS CDM組，則可以為終端分配DMRS埠0和DMRS埠2，該DMRS埠分配情況在表1中用value=11來標識，因此網路設備可直接使用表1中的value值來指示DMRS埠分配情況，此時可以不對表1進行擴展。 It should also be noted that when DMRS type 1 is used and a pre-DMRS symbol is configured, if the network device needs to configure two DMRS ports for the terminal and the two DMRS ports belong to different DMRS CDM groups, then You can assign DMRS port 0 and DMRS port 2 to the terminal. The DMRS port allocation is identified by value=11 in Table 1. Therefore, the network device can directly use the value in Table 1 to indicate the DMRS port allocation. It is not necessary to expand Table 1.

基於圖3所示的流程，並結合圖1a所示的DMRS資源示意圖，在採用DMRS類型1並配置了最多1個前置DMRS符號的情況下，如果網路設備為終端分配3個DMRS埠且該3個DMRS埠屬於不同的2個DMRS CDM組，例如，這3個DMRS埠分別為{DMRS埠0，DMRS埠1，DMRS埠3}或{DMRS埠0，DMRS埠2，DMRS埠3}或{DMRS埠1，DMRS埠2，DMRS埠3}，則表1中沒有相應的value值可以指示上述分配情況，因此需要對表1進行擴展，也即需要定義新的DMRS埠分配資訊(即value)，例如針對分配的{DMRS埠0，DMRS埠1，DMRS埠3}定義value D，針對分配的{DMRS埠0，DMRS埠2，DMRS埠3}定義value E，針對分配的{DMRS埠1，DMRS埠2，DMRS埠3}定義value F。其中，value D、value E、value F的取值可以是表1中預留value取值區間內的值。 Based on the process shown in Figure 3 and combined with the DMRS resource diagram shown in Figure 1a, when DMRS type 1 is used and a maximum of 1 pre-DMRS symbol is configured, if the network equipment allocates 3 DMRS ports for the terminal and The 3 DMRS ports belong to different 2 DMRS CDM groups. For example, the 3 DMRS ports are {DMRS port 0, DMRS port 1, DMRS port 3} or {DMRS port 0, DMRS port 2, DMRS port 3} Or {DMRS port 1, DMRS port 2, DMRS port 3}, there is no corresponding value in Table 1 to indicate the above allocation, so Table 1 needs to be extended, that is, new DMRS port allocation information (ie value), for example, value D is defined for allocated {DMRS port 0, DMRS port 1, DMRS port 3}, value E is defined for allocated {DMRS port 0, DMRS port 2, DMRS port 3}, and value E is defined for allocated {DMRS port 1, DMRS port 2, DMRS port 3} define value F. Among them, the values of value D, value E, and value F may be values in the reserved value range in Table 1.

需要說明的是，針對上述三種value值以及對應的DMRS埠分配情況，可針對其中的至少一種情況進行擴展。例如，可以在表1中增加value=13，對應的DMRS埠的索引為(0，1，3)，對應的不包含資料的DMRS CDM組的數量為2。 It should be noted that for the above three value values and corresponding DMRS port allocation situations, at least one of them can be extended. For example, you can add value=13 to Table 1, the index of the corresponding DMRS port is (0, 1, 3), and the corresponding DMRS that does not contain data The number of CDM groups is 2.

還需要說明的是，在採用DMRS類型1並配置了1個前置DMRS符號的情況下，若網路設備需要為終端配置3個DMRS埠且該3個DMRS埠屬於2個不同的DMRS CDM組，則可以為終端分配DMRS埠0、DMRS埠1和DMRS埠2，該DMRS埠分配情況在表1中用value=9來標識，因此網路設備可直接使用表1中的value值來指示DMRS埠分配情況，此時可以不對表1進行擴展。 It should also be noted that when DMRS type 1 is used and 1 pre-DMRS symbol is configured, if the network equipment needs to configure 3 DMRS ports for the terminal and the 3 DMRS ports belong to 2 different DMRS CDM groups , You can assign DMRS port 0, DMRS port 1, and DMRS port 2 to the terminal. The DMRS port allocation is identified by value=9 in Table 1, so network equipment can directly use the value in Table 1 to indicate DMRS Port allocation situation, table 1 may not be expanded at this time.

基於圖3所示的流程，並結合圖1b所示的DMRS資源示意圖，在採用DMRS類型1並配置了最多2個前置DMRS符號的情況下，若網路設備為終端分配2個或3個DMRS埠，且該2個或3個DMRS埠屬於不同的DMRS CDM組，則本發明實施例中對相應的DMRS埠分配情況所對應的DMRS埠分配資訊進行擴展，即定義新的DMRS埠分配資訊來指示上述DMRS埠分配情況。下面分別對網路設備為終端分配2個或3個DMRS埠的情況分別進行說明。 Based on the process shown in Figure 3 and combined with the DMRS resource diagram shown in Figure 1b, when DMRS type 1 is used and a maximum of 2 pre-DMRS symbols are configured, if the network equipment allocates 2 or 3 to the terminal DMRS port, and the 2 or 3 DMRS ports belong to different DMRS CDM groups, then the DMRS port allocation information corresponding to the corresponding DMRS port allocation situation is expanded in the embodiment of the present invention, that is, new DMRS port allocation information is defined To indicate the above DMRS port allocation. The following respectively describes the situation where the network equipment allocates 2 or 3 DMRS ports to the terminal.

(1)網路設備為終端分配2個DMRS埠的情況下，這2個DMRS埠包括第一埠集合中的任一個DMRS埠以及第二埠集合中的任一個DMRS埠。其中，該第一埠集合包括DMRS埠0、DMRS埠1、DMRS埠4、DMRS埠5，該第二埠集合包括DMRS埠2、DMRS埠3、DMRS埠6、DMRS埠7。該第一埠集合中的DMRS埠屬於第一DMRS CDM組，該第二埠集合中的DMRS埠屬於第二DMRS CDM組。 (1) When the network equipment allocates two DMRS ports to the terminal, the two DMRS ports include any DMRS port in the first port set and any DMRS port in the second port set. Wherein, the first port set includes DMRS port 0, DMRS port 1, DMRS port 4, and DMRS port 5. The second port set includes DMRS port 2, DMRS port 3, DMRS port 6, and DMRS port 7. The DMRS ports in the first port set belong to the first DMRS CDM group, and the DMRS ports in the second port set belong to the second DMRS CDM group.

例如，可針對以下埠組合中的一種或多種情況定義對應的value值以指示相應的DMRS埠分配情況：{0，2}，{0，3}，{0，6}，{0，7}， {1，2}，{1，3}，{1，6}，{1，7}，{4，2}，{4，3}，{4，6}，{4，7}，{5，2}，{5，3}，{5，6}，{5，7}。新定義的value值可以是表2中預留value取值區間內的值。 For example, the corresponding value can be defined for one or more of the following port combinations to indicate the corresponding DMRS port allocation: {0, 2}, {0, 3}, {0, 6}, {0, 7} , {1, 2}, {1, 3}, {1, 6}, {1, 7}, {4, 2}, {4, 3}, {4, 6}, {4, 7}, {5 , 2}, {5, 3}, {5, 6}, {5, 7}. The newly defined value can be a value in the reserved value range in Table 2.

舉例來說，如表2所示，rank=2時，需要為終端分配2個DMRS埠，如果實際使用的前置DMRS符號數為2，且不包含資料的DMRS CDM組為2時，沒有一種可以使分配的DMRS埠屬於不同的DMRS CDM組的情況。針對這一情況，可以使用一個value，對應於DMRS埠跨DMRS CDM組的情況。例如，value A對應於Number of DMRS CDM group(s) without data=2、Number of fron，且所分配的DMRS埠(DMRS port(s))為(0，2)的情況。 For example, as shown in Table 2, when rank=2, two DMRS ports need to be allocated to the terminal. If the actual number of pre-DMRS symbols used is 2, and the DMRS CDM group that does not contain data is 2, there is no one. It is possible to make the allocated DMRS ports belong to different DMRS CDM groups. For this situation, a value can be used, which corresponds to the situation where the DMRS port crosses the DMRS CDM group. For example, value A corresponds to Number of DMRS CDM group(s) without data=2, Number of fron, and the allocated DMRS port (DMRS port(s)) is (0, 2).

(2)網路設備為終端分配3個DMRS埠的情況下，這3個DMRS埠包括第一埠集合中的任兩個DMRS埠、第二埠集合中的任一個DMRS埠，或者包括該第一埠集合中的任一個DMRS埠、該第二埠集合中任兩個DMRS埠。其中，該第一埠集合包括DMRS埠0、DMRS埠1、DMRS埠4、DMRS埠5，該第二埠集合包括DMRS埠2、DMRS埠3、DMRS埠6、DMRS埠7；該第一埠集合中的DMRS埠屬於第一DMRS CDM組，該第二埠集合中的DMRS埠屬於第二DMRS CDM組。 (2) When the network equipment allocates 3 DMRS ports to the terminal, these 3 DMRS ports include any two DMRS ports in the first port set, any DMRS port in the second port set, or include the first DMRS port Any one DMRS port in a port set, and any two DMRS ports in the second port set. Wherein, the first port set includes DMRS port 0, DMRS port 1, DMRS port 4, and DMRS port 5. The second port set includes DMRS port 2, DMRS port 3, DMRS port 6, and DMRS port 7; the first port The DMRS ports in the set belong to the first DMRS CDM group, and the DMRS ports in the second port set belong to the second DMRS CDM group.

例如，可針對以下埠組合中的一種或多種情況定義對應的value值以指示相應的DMRS埠分配情況：{0，1，2}，{0，1，3}，{0，1，6}，{0，1，7}，{0，4，2}，{0，4，3}，{0，4，6}，{0，4，7}，{0，5，2}，{0，5，3}，{0，5，6}，{0，5，7}，{1，4，2}，{1，4，3}，{1，4，6}，{1，4，7}，{1，5，2}，{1，5，3}，{1，5，6}，{1，5，7}，{4，5， 2}，{4，5，3}，{4，5，6}，{4，5，7}。以上僅列舉出了第一埠集合中的2個DMRS埠與第二埠集合中的1個DMRS埠組合的情況，還可以包括第一埠集合中的1個DMRS埠與第二埠集合中的2個DMRS埠組合的情況，在此不再一一列舉。新定義的value值可以是表2中預留value取值區間內的值。 For example, the corresponding value can be defined for one or more of the following port combinations to indicate the corresponding DMRS port allocation: {0, 1, 2}, {0, 1, 3}, {0, 1, 6} , {0, 1, 7}, {0, 4, 2}, {0, 4, 3}, {0, 4, 6}, {0, 4, 7}, {0, 5, 2}, { 0, 5, 3}, {0, 5, 6}, {0, 5, 7}, {1, 4, 2}, {1, 4, 3}, {1, 4, 6}, {1, 4, 7}, {1, 5, 2}, {1, 5, 3}, {1, 5, 6}, {1, 5, 7}, {4, 5, 2}, {4, 5, 3}, {4, 5, 6}, {4, 5, 7}. The above only lists the combination of 2 DMRS ports in the first port set and 1 DMRS port in the second port set. It can also include 1 DMRS port in the first port set and 1 DMRS port in the second port set. The combination of 2 DMRS ports will not be listed here. The newly defined value can be a value in the reserved value range in Table 2.

舉例來說，如表2所示，rank=3時，需要為終端分配3個DMRS埠，如果實際使用的前置DMRS符號數為2，且不包含資料的DMRS CDM組為2時，沒有一種value可以使分配的DMRS埠屬於不同的DMRS CDM組。針對這一情況，可以使用至少一個value，對應於DMRS埠跨CDM組的情況。例如，value B對應於Number of DMRS CDM group(s) without data=2、Number of front-load symbols=2，且所分配的DMRS埠(DMRS port(s))為(0，1，2)或(0，2，3)的情況。 For example, as shown in Table 2, when rank=3, 3 DMRS ports need to be allocated to the terminal. If the actual number of pre-DMRS symbols used is 2, and the DMRS CDM group that does not contain data is 2, there is no one. The value can make the allocated DMRS ports belong to different DMRS CDM groups. For this situation, at least one value can be used, which corresponds to the situation where the DMRS port crosses the CDM group. For example, value B corresponds to Number of DMRS CDM group(s) without data=2, Number of front-load symbols=2, and the allocated DMRS port (DMRS port(s)) is (0, 1, 2) or (0, 2, 3).

基於圖3所示的流程，並結合圖2a或圖2b所示的DMRS資源示意圖，在採用DMRS類型2並配置了最多1個或2個前置DMRS符號的情況下，若網路設備為終端分配2個DMRS埠以及3個DMRS CDM組，且該2個DMRS埠屬於不同的DMRS CDM組，則本發明實施例中對相應的DMRS埠分配情況所對應的DMRS埠分配資訊進行擴展，即定義新的DMRS埠分配資訊來指示上述DMRS埠分配情況。 Based on the process shown in Figure 3, combined with the DMRS resource diagram shown in Figure 2a or Figure 2b, when DMRS type 2 is used and a maximum of 1 or 2 pre-DMRS symbols are configured, if the network device is a terminal 2 DMRS ports and 3 DMRS CDM groups are allocated, and the 2 DMRS ports belong to different DMRS CDM groups, the DMRS port allocation information corresponding to the corresponding DMRS port allocation situation is expanded in the embodiment of the present invention, that is, the definition The new DMRS port allocation information indicates the above-mentioned DMRS port allocation.

具體地，網路設備為終端分配的2個DMRS埠包括第一埠集合中的任一個DMRS埠以及第二埠集合中的任一個DMRS埠，或者包括該第一埠集合中的任一個DMRS埠以及第三埠集合中的任一個DMRS埠，或者包括該第二埠集合中的任一個DMRS埠以及該第三埠集合中的任一個DMRS埠。該第一埠集合中的DMRS埠屬於第一DMRS CDM組，該第二埠集合中的DMRS埠屬於第二DMRS CDM組，該第三埠集合中的DMRS埠屬於第三DMRS CDM組。 Specifically, the two DMRS ports allocated by the network equipment to the terminal include any DMRS port in the first port set and any DMRS port in the second port set, or include any DMRS port in the first port set And any DMRS port in the third port set, or includes any DMRS port in the second port set and any DMRS port in the third port set. The DMRS ports in the first port set belong to the first DMRS CDM group, and the second port set The DMRS port belongs to the second DMRS CDM group, and the DMRS port in the third port set belongs to the third DMRS CDM group.

其中，該前置DMRS符號的數量為1個時，該第一埠集合包括DMRS埠0、DMRS埠1，該第二埠集合包括DMRS埠2、DMRS埠3，該第三埠集合包括DMRS埠4、DMRS埠5。 Wherein, when the number of pre-DMRS symbols is 1, the first port set includes DMRS port 0 and DMRS port 1, the second port set includes DMRS port 2, DMRS port 3, and the third port set includes DMRS port 4.

DMRS port 9. The third port set includes DMRS port 4, DMRS port 5, DMRS port 10, and DMRS port 11.

舉例來說，如表3所示，rank=2，則需要為終端分配2個DMRS埠，不包含資料的DMRS CDM組為3時，則沒有一種value可以使分配的DMRS埠屬於不同的DMRS CDM組。針對這一情況，可以使用至少一個value，對應於DMRS埠跨CDM組的情況。例如，value A對應於分配的DMRS埠為(0，2)的情況。 For example, as shown in Table 3, rank=2, and 2 DMRS ports need to be allocated to the terminal. When the DMRS CDM group that does not contain data is 3, there is no value that can make the allocated DMRS ports belong to different DMRS CDMs. Group. For this situation, at least one value can be used, which corresponds to the situation where the DMRS port crosses the CDM group. For example, value A corresponds to the situation where the allocated DMRS port is (0, 2).

再例如，如表4所示，rank=2，則需要為終端分配2個DMRS埠，不包含資料的CDM組為3時，無論前置DMRS符號數為1還是2，都沒有一種value可以使分配的DMRS埠屬於不同的DMRS CDM組。針對這一情況，可以分別使用至少一個value，對應於DMRS埠跨CDM組的情況，例如：value A對應於Number of DMRS CDM group(s) without data=3，Number of front-load symbols=1，且所分配的DMRS埠(DMRS port(s))為(0，2)的情況；value B對應於Number of DMRS CDM group(s) without data=3，Number of front-load symbols=2，且所分配的DMRS埠(DMRS port(s))為(0，2)的情況。 For another example, as shown in Table 4, rank=2, and 2 DMRS ports need to be allocated to the terminal. When the CDM group that does not contain data is 3, no matter whether the number of pre-DMRS symbols is 1 or 2, there is no value that can be used. The allocated DMRS ports belong to different DMRS CDM groups. In view of this situation, at least one value can be used respectively, corresponding to the situation where the DMRS port crosses the CDM group, for example: value A corresponds to Number of DMRS CDM group(s) without data=3, Number of front-load symbols=1, And the allocated DMRS port (DMRS port(s)) is (0, 2); value B corresponds to Number of DMRS CDM group(s) without data=3, Number of Front-load symbols=2, and the allocated DMRS port (DMRS port(s)) is (0, 2).

基於圖3所示的流程，並結合圖2b所示的DMRS資源示意圖，在採用DMRS類型2並配置了最多2個前置DMRS符號的情況下，若網路設備為終端分配3個或4個DMRS埠，且該3個或4個DMRS埠屬於不同的DMRS CDM組，則本發明實施例中對相應的DMRS埠分配情況所對應的DMRS埠分配資訊進行擴展，即定義新的DMRS埠分配資訊來指示上述DMRS埠分配情況。下面分別對網路設備為終端分配2個或3個DMRS埠的情況分別進行說明。 Based on the process shown in Figure 3 and combined with the DMRS resource diagram shown in Figure 2b, when DMRS type 2 is used and a maximum of 2 pre-DMRS symbols are configured, if the network equipment allocates 3 or 4 to the terminal DMRS ports, and the 3 or 4 DMRS ports belong to different DMRS CDM groups, the DMRS port allocation information corresponding to the corresponding DMRS port allocation situation is expanded in the embodiment of the present invention, that is, new DMRS port allocation information is defined To indicate the above DMRS port allocation.
