技术领域Technical field

本发明涉及通信技术领域，尤其涉及一种下行数据的信息反馈方法及相关设备。The present invention relates to the field of communications technologies, and in particular, to an information feedback method for downlink data and related devices.

背景技术Background technique

随着移动业务的飞速发展，目前的无线通信技术如以OFDM为特征的***移动通信技术已经无法满足新的场景的需求。在学术界和工业界都大力的开展了对于第五代（5G）移动通信技术的研究。然而，新一代移动通信技术的研究和标准化工作需要在较长的一段时间内不断的演进以满足不同的场景需求，因此，在标准化的初期阶段，如何保证目前标准化的技术方案不会对后续演进的过程中可能出现的技术方案的设计造成障碍是需要重点关注的问题，即在当前的标准化过程中需要重点考虑前向兼容性。With the rapid development of mobile services, the current wireless communication technologies such as the fourth generation mobile communication technology featuring OFDM have been unable to meet the needs of new scenarios. Research on the fifth generation (5G) mobile communication technology has been vigorously carried out in academia and industry. However, the research and standardization of next-generation mobile communication technologies needs to be continuously evolved over a long period of time to meet different scenarios. Therefore, in the initial stage of standardization, how to ensure that the current standardized technical solutions will not evolve. The design of technical solutions that may arise in the process is an obstacle that needs to be focused on, that is, the current standardization process needs to focus on forward compatibility.

第五代移动通信技术需要支持超高的数据传输速率，海量的连接数以及较低的数据传输的时延以满足对于不同场景的需求。未来5G移动通信的主要场景包括以下三种：增强的移动宽带（enhanced Mobile Broadband，eMBB），大量的机器类通信（Massive Machine Type Communications，mMTC）和高可靠低时延通信（Ultra-Reliable and Low Latency Communications，URLLC）。这三种场景所针对的业务类型不一样，其需求也不一样。比如：eMBB业务主要是针对需要较高的数据速率的业务场景；mMTC业务主要是针对大量连接的业务场景； URLLC业务主要是针对时延要求以及可靠性较高的业务场景。5G移动通信的某些场景下对于用户面的数据包的时延需要在毫秒（ms）级别，因此需要支持更小力度的传输。The fifth generation of mobile communication technology needs to support ultra-high data transmission rates, massive number of connections and low data transmission delays to meet the needs of different scenarios. The main scenarios of 5G mobile communication in the future include the following three types: enhanced mobile broadband (eMBB), Massive Machine Type Communications (mMTC) and high-reliability low-latency communication (Ultra-Reliable and Low). Latency Communications, URLLC). These three scenarios are different for the type of business, and their needs are different. For example, the eMBB service is mainly for a service scenario that requires a higher data rate; the mMTC service is mainly for a large number of connected service scenarios; the URLLC service is mainly for a service scenario with a delay requirement and a high reliability. In some scenarios of 5G mobile communication, the delay of the data packet for the user plane needs to be in the millisecond (ms) level, so it is required to support transmission with less effort.

在传统的长期演进（Long Term Evolution，LTE)***的设计中，为了保证数据传输的可靠性，引入了混合自动重传请求（Hybrid Automatic Repeat reQuest，HARQ）的机制：对于一个下行传输的数据包，终端在接收到数据包之后，会在预定的子帧位置上进行ACK/NACK（应答/非应答）的反馈。例如，终端在第n个子帧上接收到了下行数据包，那么终端将在第n+4个子帧上针对所述下行数据包进行ACK/NACK信息的反馈。因此，传统的LTE下行传输的HARQ机制中数据传输与相对应的反馈时间上存在着4ms的延时。该延时的设计主要是为了简化传统的终端设计以及考虑了终端处理能力，然而这种设计无法适用于5G中的某些对于时延要求较高的场景，如URLLC。In the design of the traditional Long Term Evolution (LTE) system, in order to ensure the reliability of data transmission, a Hybrid Automatic Repeat ReQuest (HARQ) mechanism is introduced: for a downlink transmission packet. After receiving the data packet, the terminal performs ACK/NACK (answer/non-response) feedback at the predetermined subframe position. For example, if the terminal receives the downlink data packet in the nth subframe, the terminal will perform feedback of the ACK/NACK information for the downlink data packet on the n+4th subframe. Therefore, there is a 4 ms delay in the data transmission and the corresponding feedback time in the HARQ mechanism of the conventional LTE downlink transmission. The design of this delay is mainly to simplify the traditional terminal design and consider the terminal processing capability. However, this design cannot be applied to some scenarios in the 5G that require high latency, such as URLLC.

请参阅图1，在本发明一个实施例中，提供一种下行数据的信息反馈方法，包括：Referring to FIG. 1, in an embodiment of the present invention, an information feedback method for downlink data is provided, including:

步骤101：获取下行数据包对应的应答反馈指示信息；其中，所述应答反馈指示信息用于指示终端针对所述下行数据包的ACK/NACK信息反馈的时频位置；Step 101: Acquire response feedback indication information corresponding to the downlink data packet, where the response feedback indication information is used to indicate a time-frequency location of the ACK/NACK information feedback of the downlink data packet by the terminal;

步骤102：根据所述应答反馈指示信息，确定针对所述下行数据包的ACK/NACK信息反馈的时频位置；Step 102: Determine, according to the response feedback indication information, a time-frequency location of ACK/NACK information feedback for the downlink data packet.

步骤103：在确定的所述时频位置上反馈针对所述下行数据包的ACK/NACK信息。Step 103: Feed back ACK/NACK information for the downlink data packet at the determined time-frequency location.

其中，所述针对所述下行数据包的ACK/NACK信息反馈的时频位置可以是一个上行子帧的位置，也可以是在受限的时频资源内，一个数据包能够映射的最小的物理资源块。在本发明的所有实施例中，将所述在受限的时频资源内，一个数据包能够映射的最小的物理资源块定义为最小传输单元，并将受限制的时间定义为一个传输间隔。可以理解，在一个传输间隔内，可以包含多个所述最小传输单元，每一个所述最小传输单元可以用于进行上行或下行数据的传输。如果在同一个传输间隔内同时存在用于上行传输和下行传输的最小传输单元，则需要设置一个最小传输单元作为保护间隔，以实现上行传输和下行传输的转化。The time-frequency position of the ACK/NACK information feedback for the downlink data packet may be the location of one uplink subframe, or may be the smallest physical medium that a data packet can map within the limited time-frequency resource. Resource block. In all embodiments of the present invention, within the limited time-frequency resource, the smallest physical resource block that a data packet can map is defined as a minimum transmission unit, and the limited time is defined as a transmission interval. It can be understood that, within one transmission interval, a plurality of the minimum transmission units may be included, and each of the minimum transmission units may be used for transmission of uplink or downlink data. If there is a minimum transmission unit for uplink transmission and downlink transmission in the same transmission interval, a minimum transmission unit needs to be set as a guard interval to implement conversion of uplink transmission and downlink transmission.

请参阅图2，在本发明的实施例中，以一个传输间隔内包含6个最小传输单元为例来解释发明实施例中提出的方法，并且该传输间隔内包含了3个用于下行传输的最小传输单元，3个用于上行传输的最小传输单元以及1个作为保护间隔的最小传输单元。需要注意的是，这仅仅是一个示例，一个传输间隔内可以包含更多或是更少的最小传输单元，同时用于上行传输或是下行传输的最小传输单元的数量可以是变化的。基于相同的原理，本发明实施例中提出的方法同样适用于上述示例之外的情况。Referring to FIG. 2, in the embodiment of the present invention, the method proposed in the embodiment of the present invention is explained by taking six minimum transmission units in one transmission interval as an example, and the transmission interval includes three downlink transmissions. The minimum transmission unit, 3 minimum transmission units for uplink transmission and 1 minimum transmission unit as guard interval. It should be noted that this is just an example. A transmission interval may contain more or less minimum transmission units, and the number of minimum transmission units used for uplink transmission or downlink transmission may vary. Based on the same principle, the method proposed in the embodiment of the present invention is equally applicable to the case other than the above examples.

根据上述定义，所述下行数据包传输的时频位置可以是一个所述传输间隔内用于下行传输的最小传输单元，所述针对所述下行数据包的ACK/NACK信息反馈的时频位置可以同一个传输间隔内用于上行传输的最小传输单元。因此，在本发明的实施例中，所述应答反馈指示信息即用于在终端接收到所述下行数据包之后，指示终端在某一个最小传输单元上反馈针对所述下行数据包的ACK/NACK信息。可以理解，所述应答反馈指示信息可以是传输所述下行数据包与传输所述ACK/NACK信息的最小传输单元之间的间隔，例如，若所述下行数据包在一个所述传输间隔的第k个最小传输单元上传输，则所述应答反馈指示信息可以是j，当终端在第k个最小传输单元上接收到所述下行数据包之后，指示终端在第k+j个最小传输单元上反馈针对所述下行数据包的ACK/NACK信息。According to the above definition, the time-frequency location of the downlink data packet transmission may be a minimum transmission unit for downlink transmission in the transmission interval, and the time-frequency location of the ACK/NACK information feedback for the downlink data packet may be The smallest transmission unit used for uplink transmission within the same transmission interval. Therefore, in the embodiment of the present invention, the response feedback indication information is used to indicate that after receiving the downlink data packet, the terminal instructs the terminal to feed back ACK/NACK for the downlink data packet on a certain minimum transmission unit. information. It can be understood that the response feedback indication information may be an interval between the transmission of the downlink data packet and a minimum transmission unit that transmits the ACK/NACK information, for example, if the downlink data packet is in one of the transmission intervals. And transmitting, by the k minimum transmission units, the response feedback indication information may be j, and after the terminal receives the downlink data packet on the kth minimum transmission unit, indicating that the terminal is on the k+j minimum transmission unit The ACK/NACK information for the downlink data packet is fed back.

在一种实施方式中，所述获取下行数据包对应的应答反馈指示信息，包括：In an implementation manner, the obtaining the response feedback indication information corresponding to the downlink data packet includes:

具体地，可以在终端侧预先定义固定的ACK/NACK信息传输与下行数据包传输的反馈时间间隔（本实施例中可以为用于传输下行数据包和用于传输ACK/NACK信息的两个最小传输单元之间的最小传输单元个数或者所述两个最小传输单元的编号之差）作为所述预先定义的反馈指示信息，终端在收到某个最小传输单元上的下行数据包之后，则通过获取所述预先定义的反馈指示信息，并根据所述预先定义的反馈指示信息在预定的最小传输单元上反馈针对该下行数据包的ACK/NACK信息。此外，所述固定的时间间隔也可以是在基站侧预先定义好的，基站通过***信息、无线资源控制信令、媒体接入控制信令或物理层信令通知给终端，从而指示终端在对应的时频位置上反馈针对所述下行数据包的ACK/NACK信息。需要注意的是，针对不同的终端的下行数据包，基站通知下来的反馈时间间隔可以是相同的，也可以是不同的。如图3所示，若预先定义所述固定的反馈时间间隔为2个最小传输单元，那么第4，5，6个最小传输单元上分别针对第1，2，3个最小传输单元上传输的下行数据包反馈ACK/NACK信息。Specifically, the feedback time interval of the fixed ACK/NACK information transmission and the downlink data packet transmission may be predefined in the terminal side (in this embodiment, the two minimums for transmitting the downlink data packet and for transmitting the ACK/NACK information may be As the pre-defined feedback indication information, the minimum transmission unit number between the transmission units or the difference between the numbers of the two minimum transmission units is, after the terminal receives the downlink data packet on a certain minimum transmission unit, Obtaining the ACK/NACK information for the downlink data packet on a predetermined minimum transmission unit according to the predefined feedback indication information, and according to the predefined feedback indication information. In addition, the fixed time interval may also be predefined in the base station side, and the base station notifies the terminal by using system information, radio resource control signaling, media access control signaling, or physical layer signaling, thereby indicating that the terminal is corresponding. The ACK/NACK information for the downlink data packet is fed back at the time-frequency location. It should be noted that, for downlink packets of different terminals, the feedback time interval notified by the base station may be the same or different. As shown in FIG. 3, if the fixed feedback time interval is predefined as 2 minimum transmission units, then the 4th, 5th, and 6th minimum transmission units are respectively transmitted on the first, second, and third minimum transmission units. The downlink packet feeds back ACK/NACK information.

具体地，所述最小处理时间间隔为终端接收到所述下行数据包之后，处理所述下行数据包所需要的最小时间间隔。因此，可以在终端侧预先定义一个最小处理时间间隔，终端在收到某个最小传输单元上的下行数据包之后，经过一个最小处理时间间隔之后，在相应的最小传输单元上针对该下行数据包反馈ACK/NACK信息。例如，假设所述最小处理时间间隔为2个连续的最小传输单元在时域上的持续时间，则终端在第n个最小传输单元上接收到下行数据包之后，可以在第n+2个最小传输单元上或是第n+2之后的最小传输单元上反馈针对该下行数据包的ACK/NACK信息。可以理解，所述最小处理时间间隔也可以在基站侧预定义，基站通过***信息、无线资源控制信令、媒体接入控制信令或物理层信令下发给终端。Specifically, the minimum processing time interval is a minimum time interval required for processing the downlink data packet after the terminal receives the downlink data packet. Therefore, a minimum processing time interval may be predefined on the terminal side, and after receiving the downlink data packet on a certain minimum transmission unit, the terminal may, after a minimum processing time interval, target the downlink data packet on the corresponding minimum transmission unit. Feedback ACK/NACK information. For example, if the minimum processing time interval is the duration of two consecutive minimum transmission units in the time domain, the terminal may be at the n+2th minimum after receiving the downlink data packet on the nth smallest transmission unit. The ACK/NACK information for the downlink data packet is fed back on the transmission unit or the minimum transmission unit after the n+2th. It can be understood that the minimum processing time interval can also be predefined on the base station side, and the base station sends the information to the terminal through system information, radio resource control signaling, media access control signaling, or physical layer signaling.

具体地，基站可以通过显式信令告知终端反馈ACK/NACK信息的时频位置。例如，基站可以在针对所述下行数据包的下行调度指令中携带所述下行数据包对应的应答反馈指示信息。所述根据所述下行调度指令，获取所述下行数据包对应的应答反馈指示信息，包括：解析所述下行调度指令的内容，所述下行调度指令的内容中携带所述下行数据包对应的应答反馈指示信息；根据所述下行调度指令的内容，获取所述下行数据包对应的应答反馈指示信息。终端通过解析所述下行调度指令，获取所述应答反馈指示信息，进而在相应的位置上反馈ACK/NACK信息。针对某些没有调度信令指示的数据包，终端可以在基站通知的反馈ACK/NACK信息的最小传输单元的位置上反馈多个没有调度信令指示的下行数据包的ACK/NACK信息。Specifically, the base station can notify the terminal to feed back the time-frequency location of the ACK/NACK information by explicit signaling. For example, the base station may carry the response feedback indication information corresponding to the downlink data packet in a downlink scheduling instruction for the downlink data packet. Acquiring the response feedback indication information corresponding to the downlink data packet according to the downlink scheduling instruction, including: parsing the content of the downlink scheduling instruction, where the content of the downlink scheduling instruction carries a response corresponding to the downlink data packet The feedback indication information is obtained, and the response feedback indication information corresponding to the downlink data packet is obtained according to the content of the downlink scheduling instruction. The terminal obtains the response feedback indication information by parsing the downlink scheduling instruction, and further feeds back ACK/NACK information at a corresponding location. For some data packets without scheduling signaling indication, the terminal may feed back multiple ACK/NACK information of the downlink data packet without the scheduling signaling indication at the location of the minimum transmission unit of the feedback ACK/NACK information notified by the base station.

在一种实施方式中，所述根据所述下行调度指令，获取所述下行数据包对应的应答反馈指示信息，包括：In an implementation manner, the obtaining the response feedback indication information corresponding to the downlink data packet according to the downlink scheduling instruction includes:

具体地，所述下行数据包对应的应答反馈指示信息可以通过不同的加扰序列来确定。例如，可以在基站侧和终端侧预先设定加扰序列与ACK/NACK信息反馈时频位置之间的映射关系，每一种加扰序列对应映射一个应答反馈指示信息，当终端在接收到所述下行调度指令之后，通过解析所述下行调度指令的加扰序列，从而获取所述应答反馈指示信息，从而使得终端在接收到所述下行数据包之后，即可根据所述应答反馈指示信息在对应的最小传输单元上反馈针对所述下行数据包的ACK/NACK信息。Specifically, the response feedback indication information corresponding to the downlink data packet may be determined by using different scrambling sequences. For example, the mapping relationship between the scrambling sequence and the ACK/NACK information feedback time-frequency position may be preset in the base station side and the terminal side, and each scrambling sequence correspondingly maps a response feedback indication information, when the terminal receives the location After the downlink scheduling instruction is described, the response feedback indication information is obtained by parsing the scrambling sequence of the downlink scheduling instruction, so that after receiving the downlink data packet, the terminal may The corresponding minimum transmission unit feeds back ACK/NACK information for the downlink data packet.

具体地，基站可以通过显式信令告知终端反馈ACK/NACK信息的时频位置。例如，基站可以在所述下行数据包的内容中携带所述下行数据包对应的应答反馈指示信息。终端在接收到所述下行数据包之后，通过解析所述下行数据包的内容，获取所述应答反馈指示信息，进而在相应的位置上反馈ACK/NACK信息。Specifically, the base station can notify the terminal to feed back the time-frequency location of the ACK/NACK information by explicit signaling. For example, the base station may carry the response feedback indication information corresponding to the downlink data packet in the content of the downlink data packet. After receiving the downlink data packet, the terminal obtains the response feedback indication information by parsing the content of the downlink data packet, and further feeds back ACK/NACK information at a corresponding location.

具体地，基站可以通过隐式信令告知终端反馈ACK/NACK信息的时频位置。终端基于一个预先定义的映射规则，对于某个下行数据包，终端基于该下行数据包传输的传输特征来决定反馈该下行数据包的ACK/NACK信息的时频位置。其中，所述的传输特征可以是该下行数据包的传输的时频位置，或是针对该下行数据包的调度指令传输的时频位置等。例如，可以预先定义下行数据包的传输特征与反馈该下行数据包的ACK/NACK信息的时频位置之间的映射规则，当终端接收到下行数据包之后，通过获取该下行数据包对应的传输特征，进而根据所述预定义的映射规则，获取反馈该下行数据包的ACK/NACK信息的时频位置。Specifically, the base station may notify the terminal to feedback the time-frequency location of the ACK/NACK information through implicit signaling. The terminal is based on a predefined mapping rule. For a downlink data packet, the terminal determines the time-frequency location of the ACK/NACK information of the downlink data packet based on the transmission characteristics of the downlink data packet transmission. The transmission feature may be a time-frequency location of the transmission of the downlink data packet, or a time-frequency location of the scheduling instruction transmission for the downlink data packet. For example, the mapping rule between the transmission feature of the downlink data packet and the time-frequency location of the ACK/NACK information of the downlink data packet may be defined in advance, and after the terminal receives the downlink data packet, obtain the transmission corresponding to the downlink data packet. And acquiring, according to the predefined mapping rule, a time-frequency location of the ACK/NACK information that feeds back the downlink data packet.

在一种实施方式中，所述在确定的所述时频位置上反馈针对所述下行数据包的ACK/NACK信息，包括：In an implementation manner, the feeding back ACK/NACK information for the downlink data packet at the determined time-frequency location, including:

具体地，终端可能有多个可以反馈ACK/NACK信息的时频资源位置（本实施例中对应于最小传输单元），且终端可以选择在其中的一个时频资源位置上反馈ACK/NACK信息，也可以选择在多个时频资源位置上反馈ACK/NACK信息。在多个时频资源位置上反馈ACK/NACK信息的种情况下，基站需要经过一个最小处理时间间隔之后，在多个对应的时频资源位置上检测ACK/NACK信息。如图4所示，终端在第1个最小传输单元上接收到的下行数据包对应的ACK/NACK信息可以在第4个和第5个最小传输单元上进行反馈；终端在第2个和3个最小传输单元上接收到的下行数据包对应的ACK/NACK信息可以都在第6个最小传输单元上反馈。如此，则基站需要在第4个、第5个最小传输单元上检测针对第1个最小传输单元上发送的下行数据包的ACK/NACK信息；在第6个最小传输单元上检测针对第2个和第3个最小传输单元上发送的下行数据包的ACK/NACK信息。Specifically, the terminal may have multiple time-frequency resource locations (in this embodiment, corresponding to the minimum transmission unit) that can feed back ACK/NACK information, and the terminal may select to feed back ACK/NACK information on one of the time-frequency resource locations. It is also possible to choose to feed back ACK/NACK information on multiple time-frequency resource locations. In the case of feeding back ACK/NACK information on multiple time-frequency resource locations, the base station needs to detect ACK/NACK information on multiple corresponding time-frequency resource locations after a minimum processing time interval. As shown in FIG. 4, the ACK/NACK information corresponding to the downlink data packet received by the terminal on the first minimum transmission unit can be fed back on the 4th and 5th minimum transmission units; the terminal is in the 2nd and 3rd. The ACK/NACK information corresponding to the downlink data packets received on the minimum transmission unit may be fed back on the sixth minimum transmission unit. In this way, the base station needs to detect ACK/NACK information for the downlink data packet transmitted on the first minimum transmission unit on the 4th and 5th minimum transmission units; and detect the second information on the 6th minimum transmission unit. And ACK/NACK information of the downlink data packet transmitted on the third smallest transmission unit.

可以理解，在本实施例中，针对不同的终端的下行数据包，所述应答反馈指示信息不同。It can be understood that, in this embodiment, the response feedback indication information is different for downlink packets of different terminals.

可以理解，在本实施例中，所述下行数据的信息反馈方法的执行主体可以为终端，例如，手机。It can be understood that, in this embodiment, the execution body of the information feedback method of the downlink data may be a terminal, for example, a mobile phone.
