一种下行控制信息的传输方法、基站、终端及存储介质A transmission method, base station, terminal and storage medium for downlink control information

技术领域technical field

本发明涉及通信技术领域，特别是指一种下行控制信息的传输方法、基站、终端及计算机可读存储介质。The present invention relates to the field of communication technologies, and in particular, to a method for transmitting downlink control information, a base station, a terminal, and a computer-readable storage medium.

背景技术Background technique

在大规模天线系统的MU-MIMO(Multi-User Multiple-Input Multiple-Output，多用户多入多出技术)中同时传输的数据流数会大幅提高。目前，在LTE系统中，用户可以通过专用的DMRS(DeModulation Reference Signal，解调参考信号)进行信道估计，其中DMRS信号执行与数据信号相同的预编码操作。给终端通知的DCI(Downlink ControlInformation，下行控制信息)通过PDCCH(Physical Downlink Control Channel，物理下行控制信道)来传输，DCI是基于用户的，不同用户之间不需要共享DCI。In the MU-MIMO (Multi-User Multiple-Input Multiple-Output, multi-user multiple-input multiple-output technology) of the massive antenna system, the number of data streams transmitted simultaneously will be greatly increased. Currently, in an LTE system, a user can perform channel estimation through a dedicated DMRS (DeModulation Reference Signal, demodulation reference signal), where the DMRS signal performs the same precoding operation as the data signal. The DCI (Downlink Control Information, downlink control information) notified to the terminal is transmitted through a PDCCH (Physical Downlink Control Channel, physical downlink control channel), the DCI is user-based, and the DCI does not need to be shared among different users.

在5G新空口(NR:New Radio)项目启动之后，为了降低处理时延、提升系统性能，重新对DMRS导频图样进行了设计和定义。在新的DMRS导频图样中，有多种不同的导频图样。具体配置如下：After the 5G New Radio (NR: New Radio) project was launched, in order to reduce the processing delay and improve the system performance, the DMRS pilot pattern was redesigned and defined. In the new DMRS pilot pattern, there are many different pilot patterns. The specific configuration is as follows:

Configuration(配置)1：Configuration 1:

1.DMRS符号数为1:采用comb2+CS2，最大支持到4端口。1. The number of DMRS symbols is 1: comb2+CS2 is used, and the maximum support is 4 ports.

(1)见图1(最多支持4个天线端口antenna port)，其中comb2为频域复用，比如端口0和2之间就是comb2的复用关系。CS2为端口之间的序列采用循环移位方式(cyclicshifts)进行复用，比如端口0和1之间就是CS2的复用关系。(1) See Figure 1 (up to 4 antenna ports are supported), where comb2 is frequency domain multiplexing, for example, the multiplexing relationship betweenports 0 and 2 is the comb2. CS2 uses cyclic shifts to multiplex the sequence between ports. For example, betweenports 0 and 1 is the multiplexing relationship of CS2.

2.DMRS符号数为2:采用comb2+CS2+TD-OCC({1 1}和{1-1})，最大支持到8端口。2. The number of DMRS symbols is 2: using comb2+CS2+TD-OCC ({1 1} and {1-1}), the maximum support is 8 ports.

(2)见图2(最多支持8个天线端口)，TD-OCC为时域OCC(Orthogonal Cover Code，正交码)复用，比如端口0/1和4/5之间采用时域OCC复用。(2) As shown in Figure 2 (up to 8 antenna ports are supported), TD-OCC is time-domain OCC (Orthogonal Cover Code) multiplexing. For example, time-domain OCC multiplexing is used between ports 0/1 and 4/5. use.

Configuration 2Configuration 2

1.DMRS符号数为1:采用2-FD-OCC(相邻频域资源单元RE)，最大支持到6端口。1. The number of DMRS symbols is 1: 2-FD-OCC (adjacent frequency domain resource unit RE) is used, and a maximum of 6 ports are supported.

(1)见图3(最多支持6个天线端口)，2-FD-OCC，即频域OCC复用，比如端口0和1之间就是频域OCC复用。另外和其他端口之间采用FDM(Frequency Division Multiplexing，频分多路复用)方式，比如端口0/1和2/3之间采用FDM方式。(1) See Figure 3 (up to 6 antenna ports are supported), 2-FD-OCC, that is, frequency domain OCC multiplexing, for example, frequency domain OCC multiplexing betweenports 0 and 1. In addition, the FDM (Frequency Division Multiplexing, frequency division multiplexing) mode is adopted between other ports, for example, the FDM mode is adopted between ports 0/1 and 2/3.

2.DMRS符号数为2:采用2-FD-OCC(相邻频域RE)+TD-OCC({1 1}和{1-1})，最大支持到12端口。2. The number of DMRS symbols is 2: 2-FD-OCC (adjacent frequency domain RE) + TD-OCC ({1 1} and {1-1}) is used, and a maximum of 12 ports are supported.

(1)见图4(最多支持12个天线端口)，TD-OCC为时域OCC(Orthogonal Cover Code)复用，比如端口0/1和6/7之间采用时域OCC复用。(1) As shown in Figure 4 (up to 12 antenna ports are supported), TD-OCC is time-domain OCC (Orthogonal Cover Code) multiplexing. For example, time-domain OCC multiplexing is used between ports 0/1 and 6/7.

从上述DMRS各种pattern(模式)可以看出，configuration1的情况，如果支持的最大端口数不超过4，则可以用图1的pattern来配置，如果超过4，但是不超过8，可以用图2的pattern来配置；configuration2的情况，如果支持的最大端口数不超过6，则可以用图3的pattern来配置，如果超过6，但是不超过12，可以用图4的pattern来配置。在此的端口数是指该资源位置上复用的所有用户的端口数总和。It can be seen from the above DMRS patterns (patterns) that in the case ofconfiguration 1, if the maximum number of supported ports does not exceed 4, you can use the pattern in Figure 1 to configure, if it exceeds 4, but does not exceed 8, you can use Figure 2 In the case ofconfiguration 2, if the maximum number of supported ports does not exceed 6, it can be configured with the pattern in Figure 3. If it exceeds 6, but not more than 12, it can be configured with the pattern in Figure 4. The number of ports here refers to the total number of ports of all users multiplexed on the resource location.

为了支持用户在MU-MIMO下的正确解调，需要给终端通知每个调度资源上所有用户总的端口数信息。该信息对该调度资源上所有MU-MIMO的用户来说都是相同的，所以如果基于用户的PDCCH来进行信息传输，需要给所有MU-MIMO的用户都通过各自的PDCCH来传输，会导致系统资源的浪费。In order to support the correct demodulation of users under MU-MIMO, the terminal needs to be notified of the total number of ports of all users on each scheduling resource. This information is the same for all MU-MIMO users on the scheduling resource, so if the information is transmitted based on the user's PDCCH, all MU-MIMO users need to be transmitted through their own PDCCH, which will cause the system waste of resources.

也就是说，针对确定的DMRS各种配置的pattern，在MU-MIMO时，不同时频资源上，复用的用户数不同，那么就存在不同的资源上同时复用的DMRS端口数不同，根据已有的DMRS配置信息，不同的端口数可能会使用不同的DMRS导频图样。但是，该信息(导频图样)对该调度资源上所有MU-MIMO的用户来说都是相同的，所以如果基于用户的PDCCH来进行信息传输，需要给所有MU-MIMO的用户都通过各自的PDCCH来传输，会导致系统资源的浪费。That is to say, for the determined patterns of various configurations of DMRS, in MU-MIMO, the number of multiplexed users is different on different time-frequency resources, so there are different numbers of DMRS ports multiplexed simultaneously on different resources. With the existing DMRS configuration information, different port numbers may use different DMRS pilot patterns. However, this information (pilot pattern) is the same for all MU-MIMO users on the scheduling resource, so if the information is transmitted based on the user's PDCCH, it needs to be transmitted to all MU-MIMO users through their respective PDCCHs. PDCCH transmission will lead to waste of system resources.

下面结合基站和终端两侧对本发明实施例提供的所述下行控制信息的传输方法进行进一步说明。The method for transmitting the downlink control information provided by the embodiment of the present invention will be further described below with reference to both sides of the base station and the terminal.

考虑到目前5G新空口(NR:New Radio)下，有两种PDCCH可用，一种是组公共PDCCH(group common PDCCH)，一种是用户专用PDCCH(UE specific PDCCH)。NR将用户基于某些原则分为多个组，比如基于波束赋形方向，每组可以发送一个组公共PDCCH，目前组公共PDCCH只支持周期可配发送。UE周期性监听组公共PDCCH。用户专用PDCCH和LTE系统的PDCCH发送方式相同，根据调度需要随时可以发送PDCCH。Considering that under the current 5G New Radio (NR: New Radio), there are two kinds of PDCCHs available, one is group common PDCCH (group common PDCCH), and the other is user-specific PDCCH (UE specific PDCCH). NR divides users into multiple groups based on certain principles. For example, based on the beamforming direction, each group can send a group common PDCCH. Currently, the group common PDCCH only supports periodic configurable transmission. The UE periodically monitors the group common PDCCH. The user-specific PDCCH and the PDCCH of the LTE system are sent in the same manner, and the PDCCH can be sent at any time according to scheduling needs.

需要PDCCH传输的有关DMRS配置的DCI信息包含多个RBG(Resource Block Group，资源块组)资源上的端口数或者DMRS配置信息，以及本用户基于每个调度资源上的DMRS配置信息。The DCI information about the DMRS configuration that needs to be transmitted by the PDCCH includes the number of ports or DMRS configuration information on multiple RBG (Resource Block Group, resource block group) resources, and the DMRS configuration information on each scheduling resource for the user.

其中DMRS配置信息，可以定义一个配置表，通过查表方式给终端配置DMRS的各种配置信息，比如包含端口数、端口编号、FDM(频分多路复用)、CS(循环移位)、OCC、以及总的端口数(或者能支持的总端口数范围)、power offset(功率偏置)等。In the DMRS configuration information, a configuration table can be defined, and various configuration information of DMRS can be configured for the terminal by looking up the table, such as port number, port number, FDM (frequency division multiplexing), CS (cyclic shift), OCC, and the total number of ports (or the range of the total number of ports that can be supported), power offset (power offset), and so on.

如果DMRS配置表中，某一种MU-MIMO复用的总端口数的值，对应一个DMRS配置索引index，则可以通过给终端通知总端口数的方式来让终端获得该信息(从图1至图4可以看出，不同总端口数的情况下，对应的DMRS配置不一样，具体指DMRS配置占用的资源不同，比如占用一个或者两个OFDM符号)。If the value of the total number of ports for a certain MU-MIMO multiplexing in the DMRS configuration table corresponds to a DMRS configuration index index, the terminal can obtain this information by notifying the terminal of the total number of ports (from Figure 1 to It can be seen from FIG. 4 that in the case of different total port numbers, the corresponding DMRS configurations are different, which specifically means that the resources occupied by the DMRS configurations are different, such as occupying one or two OFDM symbols).

如果DMRS配置表中，某一种MU-MIMO复用的总端口数的值，对应多个DMRS配置index，则不能通过给终端通知总端口数的方式来让终端获得该信息，可以通过给终端通知该总端口数获得对应的DMRS配置index，将该index通知给终端。If the value of the total number of ports for a certain MU-MIMO multiplexing in the DMRS configuration table corresponds to multiple DMRS configuration indexes, the terminal cannot obtain this information by notifying the terminal of the total number of ports. Notify the total number of ports to obtain the corresponding DMRS configuration index, and notify the terminal of the index.

结合以上内容，针对上述技术问题，本发明实施例提供了一种下行控制信息的传输方法，可以具体包含以下几种示例(示例中传输的信息可以为总端口数或者DMRS配置index，都可以支持，区别就是比特开销不同)：In combination with the above content, in view of the above technical problems, an embodiment of the present invention provides a method for transmitting downlink control information, which may specifically include the following examples (the information transmitted in the example may be the total number of ports or the DMRS configuration index, which can support , the difference is the bit overhead):

示例一：Example one:

使用组公共PDCCH(物理下行控制信道)传输周期性的信息，作为第一级标示，比如一段时间的总端口数(多入多出复用的总端口数)或者其对应的DMRS配置信息的平均值，使用用户专用的PDCCH(终端对应的专用物理下行控制信道)传输每次调度的瞬时信息相对第一级标示信息的差值，即第二级标示，以及本用户的DMRS配置信息。比如，第一级标示为P0，第二级标示为deltaP，其中P0为周期T内的平均信息，deltaP为周期T内每个调度单位时间的信息与P0的差值。Use the group common PDCCH (Physical Downlink Control Channel) to transmit periodic information as a first-level indicator, such as the total number of ports in a period of time (the total number of multiplexed ports) or the average of its corresponding DMRS configuration information value, use the user-specific PDCCH (dedicated physical downlink control channel corresponding to the terminal) to transmit the difference between the instantaneous information of each scheduling and the first-level indicator information, that is, the second-level indicator, and the DMRS configuration information of the user. For example, the first level is marked as P0, and the second level is marked as deltaP, where P0 is the average information in the period T, and deltaP is the difference between the information of each scheduling unit time in the period T and P0.

由于组公共PDCCH是同时可以通知给多个终端，和专用PDCCH相比，开销降低，也就是示例一的方案通过采用组公共PDCCH来传输一个均值信息，专用PDCCH给出差值，相对于直接传输DMRS配置信息，可以降低传输开销。Since the group common PDCCH can be notified to multiple terminals at the same time, compared with the dedicated PDCCH, the overhead is reduced, that is, the solution of example 1 uses the group common PDCCH to transmit an average value information, and the dedicated PDCCH gives the difference, compared with direct transmission. DMRS configuration information can reduce transmission overhead.

示例二：Example two:

使用组公共PDCCH传输总端口数或者其对应的DMRS配置信息，使用用户专用PDCCH传输本用户实际调度的DMRS配置信息(本用户的DMRS配置信息)。由于现有组公共PDCCH只支持周期性发送方式，所以如果总端口数或者其对应的DMRS配置信息有变化，则可以通过事件触发的方式来触发基站发送组公共PDCCH，即通过总端口数或者其对应的DMRS配置信息是否有变化作为触发条件，来触发基站发送组公共PDCCH(事件为：总端口数或者其对应的DMRS配置信息有变化，基站自己根据该信息是否有变化，来判断是否发送专用PDCCH)。而终端对组公共PDCCH的监听方式可以有下面两种：The group public PDCCH is used to transmit the total number of ports or its corresponding DMRS configuration information, and the user-specific PDCCH is used to transmit the DMRS configuration information actually scheduled by the user (the DMRS configuration information of the user). Since the existing group public PDCCH only supports the periodic transmission mode, if the total number of ports or its corresponding DMRS configuration information changes, the base station can be triggered to send the group public PDCCH by means of event triggering. Whether there is a change in the corresponding DMRS configuration information is used as a trigger condition to trigger the base station to send the group public PDCCH (the event is: the total number of ports or its corresponding DMRS configuration information has changed, and the base station itself judges whether to send a dedicated PDCCH according to whether the information has changed. PDCCH). There are two ways for the terminal to monitor the group public PDCCH:

第一种，可以通过在用户专用PDCCH上增加1bit指示的功能，来通知终端需要接收组公共PDCCH(当确定需要发送组公共PDCCH，就需要在最近一次发送专用PDCCH的是否给出1bits的信息指示，告诉终端需要马上监听组公共PDCCH)；如果信息为1：随后在组公共PDCCH资源上搜索接收组公共PDCCH，如果信息为0：不需要在组公共PDCCH周期接收之外的时间来接收组公共PDCCH；The first is to add a 1-bit indication function to the user-specific PDCCH to notify the terminal that it needs to receive the group public PDCCH (when it is determined that the group public PDCCH needs to be sent, it is necessary to give a 1-bit information indication in the last transmission of the dedicated PDCCH or not. , tell the terminal to monitor the group public PDCCH immediately); if the information is 1: then search and receive the group public PDCCH on the group public PDCCH resources, if the information is 0: do not need to receive the group public PDCCH;

第二种，一直让终端盲检组公共PDCCH，不通过用户专用PDCCH指示组公共PDCCH是否发送。The second is to let the terminal blindly check the group common PDCCH all the time, and not to indicate whether the group common PDCCH is sent through the user-specific PDCCH.

由上可知，示例二的方案通过采用组公共PDCCH传输DMRS配置信息，可以降低系统开销，而且还可以通过专用PDCCH来告诉终端何时去接收组公共PDCCH，更加智能。It can be seen from the above that the solution of Example 2 can reduce the system overhead by using the group common PDCCH to transmit the DMRS configuration information, and can also tell the terminal when to receive the group common PDCCH through the dedicated PDCCH, which is more intelligent.

综上所述，本发明实施例提供的方案能够在新空口下，支持MU-MIMO时，正确的通过PDCCH给终端通知端口数；也就解决了如何给终端通知MU-MIMO时调度资源上的DMRS配置信息，或者是总端口数信息，或者是DMRS配置index。To sum up, the solutions provided by the embodiments of the present invention can correctly notify the terminal of the number of ports through the PDCCH when MU-MIMO is supported under the new air interface; it also solves how to notify the terminal of MU-MIMO when scheduling resources on the resource.
