技术领域Technical field
本申请涉及通信技术领域，更具体地，涉及一种通知信道质量的方法和装置。The present application relates to the field of communication technologies, and in particular, to a method and apparatus for notifying channel quality.
背景技术Background technique
在长期演进(Long Term Evolution,LTE)系统中，基站在向终端设备发送下行数据之前，并不知道信道质量的好坏。而随着无线通信系统的不断演进，对于数据传输的可靠性要求越来越高，例如在第5代移动通信技术(也称5G)中，高可靠性低时延通通信(Ultra-reliable low latency communications，URLLC)场景对数据传输可靠性的要求极高，在一些应用场景下甚至需要低于1e-9。容易想到的是，基站在完全不清楚信道质量的情况下发送下行数据，传输的可靠性则难以保证。In a Long Term Evolution (LTE) system, a base station does not know the quality of a channel before transmitting downlink data to a terminal device. With the continuous evolution of wireless communication systems, the reliability requirements for data transmission are getting higher and higher. For example, in the 5th generation mobile communication technology (also called 5G), high reliability and low latency communication (Ultra-reliable low) The latency communications (URLLC) scenario has extremely high requirements for data transmission reliability, and in some applications, it may even need to be lower than 1e-9. It is easy to think that the base station transmits downlink data without completely knowing the channel quality, and the reliability of the transmission is difficult to guarantee.
目前，对于如何满足未来通信系统中对于数据传输可靠性的高要求，业界缺乏一种可行的方案。At present, the industry lacks a feasible solution to how to meet the high requirements for data transmission reliability in future communication systems.
发明内容Summary of the invention
本申请提供一种通知信道质量的方法，能够提高数据传输的可靠性。The present application provides a method for notifying channel quality, which can improve the reliability of data transmission.
第一方面，本申请提供一种通知信道质量的方法，所述方法包括：In a first aspect, the application provides a method for notifying channel quality, the method comprising:
终端设备获取信道质量信息；The terminal device acquires channel quality information;
所述终端设备根据获取的信道质量信息，从预存的映射表中选取参考信道质量指示CQI的索引，所述映射表包括CQI的索引和信道质量信息之间的映射关系；Determining, by the terminal device, an index of a reference channel quality indicator CQI from a pre-stored mapping table according to the acquired channel quality information, where the mapping table includes a mapping relationship between an index of the CQI and channel quality information;
所述终端设备发送第一指示信息，所述第一指示信息用于指示所述参考CQI的索引；The terminal device sends first indication information, where the first indication information is used to indicate an index of the reference CQI;
所述终端设备从所述网络设备接收第二指示信息，所述第二指示信息用于指示目标CQI的索引；Receiving, by the network device, the second indication information, where the second indication information is used to indicate an index of the target CQI;
所述终端设备根据所述目标CQI的索引，从所述映射表中确定所述目标CQI对应的信道质量信息。Determining, by the terminal device, channel quality information corresponding to the target CQI from the mapping table according to an index of the target CQI.
在一种可能的设计中，目标CQI的索引与参考CQI的索引可以相同也可以不同。In one possible design, the index of the target CQI may be the same as or different from the index of the reference CQI.
在一种可能的设计中，信道质量信息包括调制阶数、码率或频谱效率中的至少一个。In one possible design, the channel quality information includes at least one of a modulation order, a code rate, or a spectral efficiency.
在一种可能的设计中，所述映射表中任意一个CQI的索引和信道质量信息之间的映射关系包含在表1至表96中的任意一个表格中。In a possible design, the mapping relationship between the index of any one of the CQIs and the channel quality information in the mapping table is included in any one of Tables 1 to 96.

在本申请实施例中，终端设备和网络设备预存有至少记录了CQI的索引和信道质量信息的映射关系的映射表。而CQI的索引是对信道质量量化后的序号，因此每一个CQI的索引可以反映出信道质量的好坏。终端设备首先衡量信道质量的好坏，并从预存的映射表中选取反映当前信道质量的CQI的索引，并反馈给网络设备。这样，网络设备结合终端设备反馈的参考CQI的索引，并结合当前网络资源情况，决定发送下行数据时的信道质量信息和编码方式(如果CQI的索引与编码方式对应)等，并将最终选择的目标CQI的索引返回至终端设备。后续，网络设备可以使用和目标CQI的索引对应的信道质量信息和编码方式(如果CQI的索引与编码方式对应)等向终端设备发送数据，从而可以提高数据传输的可靠性。In the embodiment of the present application, the terminal device and the network device pre-store a mapping table that records at least the mapping relationship between the CQI index and the channel quality information. The CQI index is the sequence number quantized by the channel quality, so the index of each CQI can reflect the quality of the channel. The terminal device first measures the quality of the channel, and selects an index of the CQI reflecting the current channel quality from the pre-stored mapping table, and feeds back to the network device. In this way, the network device combines the index of the reference CQI fed back by the terminal device, and combines the current network resource condition, determines the channel quality information and the coding mode (if the CQI index corresponds to the coding mode) when the downlink data is sent, and finally selects The index of the target CQI is returned to the terminal device. Subsequently, the network device can transmit data to the terminal device by using channel quality information and an encoding method corresponding to the index of the target CQI (if the index of the CQI corresponds to the encoding mode), thereby improving the reliability of data transmission.

第三方面，本申请提供一种通知信道质量的方法，包括：In a third aspect, the application provides a method for notifying channel quality, including:
网络设备确定与终端设备之间通信需要采用的信道质量信息；The network device determines channel quality information to be used for communication with the terminal device;
所述网络设备根据所述确定的信道质量信息，从预存的映射表中选取目标CQI的索引，所述映射表包括CQI的索引和信道质量信息之间的映射关系；The network device selects an index of the target CQI from the pre-stored mapping table according to the determined channel quality information, where the mapping table includes a mapping relationship between the CQI index and the channel quality information;

在一种可能的设计中，目标CQI的索引与参考CQI的索引可以相同也可以不同。In one possible design, the index of the target CQI may be the same as or different from the index of the reference CQI.
在一种可能的设计中，网络设备从终端设备接收用于指示参考CQI的索引的指示信息。In one possible design, the network device receives indication information from the terminal device indicating an index of the reference CQI.
进一步地，以上第一方面、第二方面和第三方面的方法中，设计的多个映射表，可以应用于不同的可靠性需求。为不同块差错率BLER需求的多个场景都提供了一种简单、可行的方案。Further, in the methods of the above first aspect, the second aspect, and the third aspect, the plurality of mapping tables designed may be applied to different reliability requirements. A simple and feasible solution is provided for multiple scenarios of different block error rate BLER requirements.
同时适用于第一方面、第二方面和第三方面的通知信道质量的方法，在某些实现方式中，映射表中的调制阶数的第一取值集合与编码方式中的第一编码方式对应，调制阶数的第二取值集合与编码方式中的第二编码方式对应，第一取值集合和第二取值集合中包括调制阶数的至少一个取值。The method for notifying the channel quality of the first aspect, the second aspect, and the third aspect, in some implementation manners, the first value set of the modulation order in the mapping table and the first coding mode in the coding mode Correspondingly, the second set of values of the modulation order corresponds to the second coding mode in the coding mode, and the first value set and the second value set include at least one value of the modulation order.
在这种实现方式中，编码方式可以和调制阶数的取值具有映射关系。例如，调制阶数的取值等于2时，编码方式采用Polar码，调制阶数等于4或6时，编码方式采用LDPC BG2。当然还可以是其它的映射关系。这样，CQI映射表中甚至不需要再出现编码方式这一列，而根据调制阶数直接隐式的确定。这里不再一一列举。In this implementation, the coding mode can be mapped to the value of the modulation order. For example, when the value of the modulation order is equal to 2, the coding mode adopts a Polar code, and when the modulation order is equal to 4 or 6, the coding mode adopts LDPC BG2. Of course, it can also be other mapping relationships. In this way, the CQI mapping table does not even need to appear in the coding mode column, but is directly implicitly determined according to the modulation order. It is not listed here one by one.
应理解，这里所说的第一编码方式和第二编码方式仅是表示两种不同的编码方式，但并不限定第一编码方式和第二编码方式具体采用哪种码。同样地，第一取值集合和第二取值集合也仅是表示两个不同的取值集合，每个取值集合至少包括调制阶数的一个取值。显然，调制阶数可以不限于仅有两个取值集合，例如还可以是3个或4个取值集合。任意两个取值集合之间的关系都满足这里第一取值集合和第二取值集合的关系。It should be understood that the first coding mode and the second coding mode mentioned herein only represent two different coding modes, but it is not limited to which code is specifically used by the first coding mode and the second coding mode. Similarly, the first set of values and the second set of values also represent only two different sets of values, each set of values including at least one value of the modulation order. Obviously, the modulation order may not be limited to only two sets of values, for example, it may be 3 or 4 sets of values. The relationship between any two sets of values satisfies the relationship between the first set of values and the second set of values.

为了便于理解，首先对本申请涉及的相关概念作简单介绍。For ease of understanding, the related concepts involved in this application are briefly introduced.
5G作为下一代无线通信几乎是，在3GPP和其它各种国际标准化组织得到广泛的重视和研究。信道编码技术是通信技术领域一种常用的提高数据传输可靠性的方法。5G中提出数据信道将采用低密度奇偶检验码(Low Density Parity Check，LDPC)编码，控制信道将采用Polar编码。5G as a next-generation wireless communication is almost universally recognized and researched in 3GPP and various other international standardization organizations. Channel coding technology is a commonly used method in the field of communication technology to improve the reliability of data transmission. The data channel proposed in 5G will be encoded by Low Density Parity Check (LDPC), and the control channel will be Polar coded.
LDPC是一类具有稀疏校验矩阵的线性分组码，即是说LDPC码的校验矩阵中零元素远远多于非零元素，且非零元素的分布没有规律。其中，一个码长等于N，信息序列的长度等于K的线性分组码可以由其校验矩阵唯一确定。LDPC码不仅具有逼近香农极限的良好性能，而且译码复杂度较低，结构灵活，是近年来信道编码领域研究的热点，目前已经广泛应用于深空通信、光纤通信、卫星数字视频和音频广播等领域。准循环低密度奇偶检验码(Quasi-Cyclic Low Density Parity Check，QC-LDPC)是LDPC的一个子类。 QC-LDPC的校验矩阵(parity check matrix)是对一个基矩阵进行扩展得到的，QC-LDPC的校验矩阵具有描述简单、易于构造等特点。在3GPP TS38.212.V15.0.0(2017-12)中，引入了LDPC的两种不同的基矩阵(base graph，BG)BG1和BG2进行LDPC编码，具体可以参见文献3GPP TS38.212.V15.0.0(2017-12)。LDPC is a kind of linear block code with sparse check matrix. That is to say, the check matrix of LDPC code has far more zero elements than non-zero elements, and the distribution of non-zero elements is irregular. Wherein, a linear block code whose code length is equal to N and whose length of the information sequence is equal to K can be uniquely determined by its check matrix. LDPC codes not only have good performance close to the Shannon limit, but also have low decoding complexity and flexible structure. They are hotspots in the field of channel coding in recent years, and have been widely used in deep space communication, optical fiber communication, satellite digital video and audio broadcasting. And other fields. Quasi-Cyclic Low Density Parity Check (QC-LDPC) is a subclass of LDPC. The parity check matrix of QC-LDPC is obtained by extending a base matrix. The check matrix of QC-LDPC has the characteristics of simple description and easy construction. In 3GPP TS 38.212.V15.0.0 (2017-12), two different base graphs (BG) BG1 and BG2 of LDPC are introduced for LDPC coding. For details, refer to the document 3GPP TS 38.212.V15. 0.0 (2017-12).

本申请实施例的技术方案适用于通过终端设备向网络设备上报信道质量指示CQI，以提高数据传输可靠性的场景。下文以5G中新空口(new radio，NR)技术中的URLLC场景作为示例，对本申请实施例的通知信道质量的方法的过程作介绍。The technical solution of the embodiment of the present application is applicable to a scenario in which a channel quality indicator CQI is reported to a network device by a terminal device to improve data transmission reliability. The process of the method for notifying the channel quality in the embodiment of the present application is described below by taking the URLLC scenario in the new radio (NR) technology in the 5G as an example.
参见图2，图2是本申请实施例的通知信道质量的方法200的示意性交互图。应理解，步骤210至260仅是为了说明通知信道质量的方法200的过程，不应对方法200构成限定。这些步骤也可以拆分为更多的步骤，或者合并为更少的步骤。Referring to FIG. 2, FIG. 2 is a schematic interaction diagram of a method 200 for notifying channel quality according to an embodiment of the present application. It should be understood that steps 210 through 260 are merely illustrative of the process of method 200 for notifying channel quality, and that method 200 should not be limited. These steps can also be split into more steps or combined into fewer steps.
210、终端设备获取信道质量信息，并根据获取的信道质量信息从预存的映射表中选取参考CQI的索引。所述信道质量信息可以包括调制阶数、码率或频谱效率中的至少一个。终端设备获取的信道质量信息可以反映当前信道质量的好坏。信道质量的好坏可以量化为信道质量指示(Channel Quality Indicator，CQI)的索引来表征。210. The terminal device acquires channel quality information, and selects an index of the reference CQI from the pre-stored mapping table according to the obtained channel quality information. The channel quality information may include at least one of a modulation order, a code rate, or a spectral efficiency. The channel quality information acquired by the terminal device may reflect the quality of the current channel. The quality of the channel can be quantified as an index of the Channel Quality Indicator (CQI).
本文中所说的映射表也可以称作CQI的索引表或者调制编码方案(modulation and coding scheme,MCS)表。其中，映射表包括CQI的索引和信道质量信息之间的映射关系，例如，包括CQI的索引和调制阶数、码率或频谱效率中至少一个的映射关系。The mapping table referred to herein may also be referred to as an index table of CQI or a modulation and coding scheme (MCS) table. The mapping table includes a mapping relationship between the index of the CQI and the channel quality information, for example, a mapping relationship including an index of the CQI and at least one of a modulation order, a code rate, or a spectrum efficiency.
调制阶数决定了1个符号中传输的比特数。例如，正交相移键控(Quadrature Phase Shift Keying，QPSK)对应的调制阶数为2，16QAM(正交振幅调制，Quadrature Amplitude Modulation)的调制阶数为4，而64QAM的调制阶数为6。The modulation order determines the number of bits transmitted in one symbol. For example, Quadrature Phase Shift Keying (QPSK) corresponds to a modulation order of 2, 16QAM (Quadrature Amplitude Modulation) has a modulation order of 4, and 64QAM has a modulation order of 6 .
码率为传输块中信息比特数与物理信道的总比特数之间的比值。The code rate is the ratio between the number of information bits in the transport block and the total number of bits of the physical channel.
频谱效率表示一个资源单元(resource element,RE)所能承载的信息比特。Spectrum efficiency represents the information bits that a resource element (RE) can carry.
可以理解的是，网络设备在发送下行数据之前，并不清楚数据信道的条件如何，为了提高数据传输的可靠性，可以由终端设备衡量信道质量的好坏，并反馈至网络设备。通信协议将信道质量量化为0-15的序列，并定义为CQI。每个CQI对应一个索引(下文称作CQI的索引)。鉴于终端设备反馈给网络设备的CQI仅是作为一个参考，因此，本文中将终端设备反馈给网络设备的CQI的索引称作参考CQI的索引。It can be understood that the network device does not know the condition of the data channel before transmitting the downlink data. To improve the reliability of the data transmission, the terminal device can measure the quality of the channel and feed back to the network device. The communication protocol quantizes the channel quality to a sequence of 0-15 and is defined as CQI. Each CQI corresponds to an index (hereinafter referred to as an index of CQI). Since the CQI that the terminal device feeds back to the network device is only used as a reference, the index of the CQI that the terminal device feeds back to the network device herein is referred to as the index of the reference CQI.
220、终端设备向网络设备发送第一指示信息，网络设备从终端设备接收第一指示信息。其中，第一指示信息用于指示参考CQI的索引。220. The terminal device sends the first indication information to the network device, where the network device receives the first indication information. The first indication information is used to indicate an index of the reference CQI.
本文对第一指示信息的形式不作限定，本领域技术人员容易想到多种可行的方式由终端设备向网络设备上报参考CQI的索引。例如，终端设备可以通过4比特向网络设备指示参考CQI的索引，代表最多16种可能。当然，此处的4比特只是一种举例，如果CQI的种类越少的话所需的比特数也就越少，如果CQI的种类越多的话所需的比特数也就越多。The form of the first indication information is not limited herein. A person skilled in the art can easily think of a plurality of possible ways for the terminal device to report the index of the reference CQI to the network device. For example, the terminal device can indicate the index of the reference CQI to the network device by 4 bits, representing up to 16 possibilities. Of course, the 4 bits here are only an example. If the number of CQIs is smaller, the number of bits required is smaller. If the number of CQIs is larger, the number of bits required is larger.
230、网络设备确定发送数据实际需要采用的信道质量信息，例如调制阶数、码率或频谱效率。230. The network device determines channel quality information that is actually needed to transmit data, such as modulation order, code rate, or spectrum efficiency.
在步骤230中，网络设备可以根据网络资源情况确定发送数据实际需要采用的信道质量信息，例如调制阶数、码率或频谱效率。或者，也可以结合终端设备上报的参考CQI的索引，从映射表中确定参考CQI对应的信道质量信息，例如调制阶数、码率或频谱效 率，这样也可以获知当前信道质量，进而确定发送数据实际需要采用的信道质量信息，例如调制阶数、码率或频谱效率。In step 230, the network device may determine channel quality information, such as modulation order, code rate, or spectrum efficiency, that the transmission data actually needs to be used according to the network resource condition. Alternatively, the channel quality information corresponding to the reference CQI, such as the modulation order, the code rate, or the spectrum efficiency, may be determined from the mapping table in combination with the index of the reference CQI reported by the terminal device, so that the current channel quality may be known, and the transmission data may be determined. Channel quality information that is actually required, such as modulation order, code rate, or spectral efficiency.
240、网络设备根据发送数据实际需要采用的信道质量信息，例如调制阶数、码率或频谱效率，从预存的映射表中选取目标CQI的索引。实际采用的目标CQI的索引与参考CQI的索引可以相同也可以不同。240. The network device selects an index of the target CQI from the pre-stored mapping table according to channel quality information, such as modulation order, code rate, or spectrum efficiency, which is actually required to transmit the data. The index of the target CQI actually used may be the same as or different from the index of the reference CQI.
同样地，映射表包括CQI的索引和信道质量信息的映射关系。不难理解，网络设备与终端设备采用的CQI映射表是一致的。Similarly, the mapping table includes a mapping relationship between the index of the CQI and the channel quality information. It is not difficult to understand that the CQI mapping table adopted by the network device and the terminal device is consistent.
250、网络设备向终端设备发送第二指示信息，终端设备从网络设备接收第二指示信息。250. The network device sends second indication information to the terminal device, where the terminal device receives the second indication information from the network device.
其中，第二指示信息指示目标CQI的索引。The second indication information indicates an index of the target CQI.
260、终端设备根据目标CQI的索引，从映射表中确定与目标CQI的索引对应的信道质量信息，例如，确定调制阶数、码率和编码方式中的至少一种。后续终端设备并根据确定的调制阶数和码率对于收到的数据进行处理。260. The terminal device determines, according to the index of the target CQI, channel quality information corresponding to the index of the target CQI from the mapping table, for example, determining at least one of a modulation order, a code rate, and an encoding manner. The subsequent terminal device processes the received data according to the determined modulation order and code rate.
可以理解的是，目标CQI可以与参考CQI相同或者不同。网络设备可以根据当前网络资源情况，确定发送数据实际需要采用的信道质量信息，例如调制阶数、码率或频谱效率，从而从映射表中选取与实际需要采用的调制阶数、码率或频谱效率对应的目标CQI的索引。或者，网络设备也可以结合当前网络资源情况和参考CQI的索引，选取目标CQI的索引。最终，网络设备将选取的目标CQI的索引通过第二指示信息通知终端设备。通过本申请实施例的方法，使得网络设备在发送数据之前，参考了当前信道质量的好坏，因此，可以提高数据传输的可靠性。It can be understood that the target CQI can be the same as or different from the reference CQI. The network device can determine channel quality information, such as modulation order, code rate, or spectrum efficiency, that is actually needed to transmit data according to the current network resource condition, so as to select a modulation order, a code rate, or a spectrum that is actually needed from the mapping table. The index of the target CQI corresponding to the efficiency. Alternatively, the network device may also select an index of the target CQI in combination with the current network resource condition and the index of the reference CQI. Finally, the network device notifies the terminal device of the selected index of the target CQI by using the second indication information. With the method of the embodiment of the present application, the network device refers to the current channel quality before sending the data, and therefore, the reliability of the data transmission can be improved.
事实上，当该映射表应用于上行数据发送的时候，原则是类似的，只是不再需要由终端设备反馈参考CQI的索引，网络设备可以直接根据上行的信道确定上行所采用的调制阶数、码率和编码方式中的至少一种，并根据映射表确定发送上行数据所需的目标CQI的索引，并将该索引通过指示信息发送给终端设备。终端设备可以根据收到的目标CQI的索引以及映射表确定收到的目标CQI的索引对应的调制阶数和码率，并根据确定的调制阶数和码率对于待发送的上行数据进行处理。In fact, when the mapping table is applied to uplink data transmission, the principle is similar, except that the terminal device does not need to feed back the index of the CQI, and the network device can directly determine the modulation order used by the uplink according to the uplink channel, At least one of a code rate and an encoding mode, and determining an index of a target CQI required for transmitting the uplink data according to the mapping table, and transmitting the index to the terminal device by using the indication information. The terminal device may determine the modulation order and the code rate corresponding to the index of the received target CQI according to the received index of the target CQI and the mapping table, and process the uplink data to be sent according to the determined modulation order and code rate.
如果系统支持多种信道编码方式，那么映射表中还包括编码方式信息，则确定参考CQI的索引或目标CQI的索引时还要考虑编码方式，而相应的，终端接收到目标CQI的索引时可以根据目标CQI的索引确定编码方式。上下行传输时具体的目标CQI的索引确定方式与前述的实施例一致，不再赘述。If the system supports multiple channel coding modes, the mapping table further includes coding mode information, and the coding mode is also considered when determining the index of the reference CQI or the index of the target CQI, and correspondingly, when the terminal receives the index of the target CQI, The encoding method is determined according to the index of the target CQI. The manner of determining the index of the specific target CQI in the uplink and downlink transmission is consistent with the foregoing embodiment, and details are not described herein again.
目前，5G作为下一代无线通信技术，在3GPP和其它各种国际标准化组织得到了广泛的重视和研究。其可以满足运营商对于各种工业、垂直市场和各种虚拟运营业务的定制化需求。5G包括三大场景：增强型移动带宽(Enhanced Mobile BroadBand，eMBB),高可靠性低时延通信(Ultra-reliable low latency communications，URLLC)和海量机器类型通信(Massive Machine type communications，mMTC)。其中，URLLC场景的目标误块率(block error rate，BLER)公认需要低于10％，甚至需要包括10-4(即1e-4)或者更低。同时考虑到URLLC场景下包括多个不同的使用场景(use case)，而不同的使用场景的对于BLER的需求不同，跨度较大。如果仅设计一种映射表并不合适。例如， 如果多个使用场景的数据传输采用同一个映射表，则可能有些使用场景的BLER无法保证，而有一些使用场景的BLER又过于严格，没有必要。At present, 5G as a next-generation wireless communication technology has received extensive attention and research in 3GPP and various other international standardization organizations. It can meet the operator's customized needs for various industrial, vertical markets and various virtual operations. 5G includes three major scenarios: Enhanced Mobile Broad Band (eMBB), Ultra-reliable low latency communications (URLLC) and Massive Machine Type Communications (mMTC). Among them, the target block error rate (BLER) of the URLLC scenario is recognized to be less than 10%, and even needs to include 10-4 (ie, 1e-4) or lower. At the same time, it is considered that the URLLC scenario includes a plurality of different use cases, and different usage scenarios have different requirements for the BLER, and the span is larger. It is not appropriate to design only one mapping table. For example, if the data transmission of multiple usage scenarios uses the same mapping table, there may be some BLERs that cannot use the scenario, and some BLERs that use the scenario are too strict and unnecessary.
为此，进一步地，本申请提出一种映射表的设计方案，旨在设计出可以满足不同BLER需求的映射表。在具有不同BLER需求的使用场景下，数据传输的可靠性都可以得到一定程度的保障。To this end, further, the present application proposes a design scheme of a mapping table, which aims to design a mapping table that can meet different BLER requirements. In a usage scenario with different BLER requirements, the reliability of data transmission can be guaranteed to a certain extent.
下面对本申请设计的映射表作详细介绍。The mapping table designed by this application is described in detail below.
以下我们将不同使用场景下所需求的BLER称作目标BLER。鉴于本文中给出了多种可行的映射表的形式，为了清楚起见，我们按照映射表中涉及的编码方式一一进行介绍。在每一种编码方式下，又按照不同的目标BLER对以及系统对码率的限制情况，分别给出映射表的一些映射形式。Below we refer to the BLER required in different usage scenarios as the target BLER. In view of the various feasible mapping table forms given in this paper, for the sake of clarity, we will introduce them according to the coding methods involved in the mapping table. In each coding mode, according to different target BLER pairs and the system's limitation on the code rate, some mapping forms of the mapping table are respectively given.
下文给出的映射表中涉及到的编码方式包括：Polar和LDPC BG2，其中LDPC BG2表示根据基矩阵BG2得到的LDPC。The coding methods involved in the mapping table given below include: Polar and LDPC BG2, where LDPC BG2 represents the LDPC obtained from the base matrix BG2.
根据信道编码的特点，一般还会规定最小码率和最大码率。Depending on the characteristics of the channel coding, the minimum code rate and the maximum code rate are generally specified.
在实际工作中，为了简化设计，即使考虑不同的场景采用不同的目标BLER，还是采用相同的映射表的信噪比(signal-to-noise ratio，SNR)或者相同的信干噪比(signal-to-interference-noise ratio，SINR)范围(不失一般性，以下均以SNR为例)，每个CQI的索引对应的SNR工作点尽量一致，这样在查表时，就不需要必须按照先确定目标BLER对应的表格再根据SNR确定CQI的索引的先后顺序从而得到码率、频谱效率和/或调制方式等信息，也可以先按SNR确定CQI的索引再根据目标BLER确定对应的表格从而得到码率、频谱效率和/或调制方式等信息，具有一定的灵活性。例如，在具体设计映射表格的时候，如果考虑两个目标BLER，就要将这两个目标BLER成对考虑。不难理解，在同样的SNR，目标BLER的值较大的场景下码率较高，可以传输较多的信息比特，而目标BLER的值较小的场景下码率较低，可以传输的信息比特较少。因此对于一个目标BLER对来说，最小码率针对的是具有较小值的目标BLER，而最大码率针对的是具有较大值的目标BLER。In practical work, in order to simplify the design, even if different target BLERs are used in consideration of different scenarios, the signal-to-noise ratio (SNR) of the same mapping table or the same signal-to-noise ratio (signal-) is adopted. To-interference-noise ratio (SINR) range (without loss of generality, SNR is taken as an example below). The SNR working point corresponding to the index of each CQI is as consistent as possible, so that it is not necessary to first determine when checking the table. The table corresponding to the target BLER further determines the order of the CQI index according to the SNR to obtain information such as a code rate, a spectrum efficiency, and/or a modulation mode, and may also determine an index of the CQI according to the SNR, and then determine a corresponding table according to the target BLER to obtain a code. Information such as rate, spectral efficiency and/or modulation method has certain flexibility. For example, when designing a mapping table specifically, if two target BLERs are considered, the two target BLERs are considered in pairs. It is not difficult to understand that in the scenario where the same SNR and the target BLER value are large, the code rate is high, and more information bits can be transmitted, and the information rate of the target BLER having a smaller value is lower, and the information that can be transmitted is lower. Less bits. Thus for a target BLER pair, the minimum code rate is for a target BLER with a smaller value and the maximum code rate is for a target BLER with a larger value.
下面给出本申请设计的映射表。需要说明的是，本文中所有表中的码率不是实际码率，实际码率应是表中的’码率’的取值除以1024。这也是业界常用的表示方法。另外，涉及的SE_max表示该表设计过程中考虑的最大频谱效率，具体为最大码率乘以最大调制阶数，其表达式为SE_max＝CR/1024*M，其中CR为一个目标BLER对中较低目标BLER对应的表格中最高阶调制下的最大码率的值，CR/1024即为实际的最高阶调制下的最大码率，M为系统支持的最大调制阶数，例如当系统最多支持64QAM时，M＝6。本文以4个目标BLER对为例，分别是{1e-3,1e-5}，{1e-1,1e-5}，{1e-2,1e-4}和{1e-1,1e-4}。所有目标BLER对的最小效率均为30/1024*2，最大效率则取了4种可能性(即666/1024*6，772/1024*6，873/1024*6，948/1024*6)，通过仿真，可以说明这些表格中的取值能得到较好的性能，因此为较优的值。The mapping table designed by this application is given below. It should be noted that the code rate in all the tables in this paper is not the actual code rate, and the actual code rate should be the value of the 'code rate' in the table divided by 1024. This is also a common representation in the industry. In addition, the SE_max involved indicates the maximum spectral efficiency considered in the design process of the table, specifically the maximum code rate multiplied by the maximum modulation order, and its expression is SE_max=CR/1024*M, where CR is a target BLER pair. The value of the maximum bit rate under the highest order modulation in the table corresponding to the low target BLER, CR/1024 is the maximum bit rate under the actual highest order modulation, and M is the maximum modulation order supported by the system, for example, when the system supports up to 64QAM When M=6. In this paper, four target BLER pairs are taken as {1e-3, 1e-5}, {1e-1, 1e-5}, {1e-2, 1e-4} and {1e-1, 1e-4. }. The minimum efficiency of all target BLER pairs is 30/1024*2, and the maximum efficiency takes 4 possibilities (ie 666/1024*6,772/1024*6, 873/1024*6, 948/1024*6) Through simulation, it can be shown that the values in these tables can get better performance, so it is a better value.
1、编码方式仅涉及LDPC BG2码。1. The coding method only involves the LDPC BG2 code.
1.1 目标BLER对{1e-3,1e-5}1.1 Target BLER pair {1e-3, 1e-5}
1.1.1 SE_max＝666/1024*6，其中CR＝666，为具有较大值的目标BLER(这里是1e-3)对应的最大码率，M＝6，下文中的SE_max均为如此定义，因此不再赘述。1.1.1 SE_max=666/1024*6, where CR=666, which is the maximum code rate corresponding to the target BLER (here 1e-3) with a larger value, M=6, and the SE_max in the following is defined as follows. Therefore, it will not be repeated.

这里以表1为例给出一个根据频谱效率、码率或调制阶数选取CQI的索引的例子，本文中所有表格都适用这个原则的。例如，根据信道质量或者其他计算方法得到SE＝0.17，则从表1中选取小于或等于0.17，且与0.17最接近的SE的取值对应的CQI的索引，即对应的CQI的索引为2。又例如，根据信道质量或者其他计算方法得到码率为60，则从表1中选取小于或等于60，且与60最接近的码率的取值对应的CQI的索引，即对应的CQI的索引为1。在本申请实施例中，终端设备选取参考CQI的索引，或者网络设备选取目标CQI的索引都遵循这个原则。终端接收到目标CQI的索引时，可以根据该索引从表1读取相应的频谱效率、码率或调制阶数用于下行数据接收或者上行数据发送，同样地，本文所有表格都适用这个原则。Here, an example of selecting an index of CQI according to spectral efficiency, code rate or modulation order is given by using Table 1 as an example. All the tables in this paper apply this principle. For example, if SE=0.17 is obtained according to the channel quality or other calculation method, the index of the CQI corresponding to the value of the SE that is less than or equal to 0.17 and closest to 0.17 is selected from Table 1, that is, the index of the corresponding CQI is 2. For another example, if the code rate is 60 according to the channel quality or other calculation method, the index of the CQI corresponding to the value of the code rate that is less than or equal to 60 and closest to 60 is selected from Table 1, that is, the index of the corresponding CQI. Is 1. In the embodiment of the present application, the terminal device selects the index of the reference CQI, or the network device selects the index of the target CQI to follow this principle. When receiving the index of the target CQI, the terminal may read the corresponding spectrum efficiency, code rate or modulation order from Table 1 for downlink data reception or uplink data transmission according to the index. Similarly, all the tables in this paper apply this principle.

为了方便描述，上述表1-32中包括了CQI的索引与频谱效率、码率和调制阶数之间的映射关系，但是在实际应用中表1-32中也可以只包括CQI的索引与频谱效率、码率和调制阶数中的至少一个之间的映射关系。For the convenience of description, the mapping between the CQI index and the spectrum efficiency, the code rate, and the modulation order is included in the above table 1-32. However, in the actual application, the index and the spectrum of the CQI may be included in the table 1-32. A mapping relationship between at least one of efficiency, code rate, and modulation order.
当CQI的索引小于16个时，实际使用的映射表可以是上述表1-32中任意一个表的一部分。当CQI的索引大于16个时，上述表1-32中任意一个表可以是实际使用的映射表的一部分。当然，CQI的索引号也有可能发生相应的变化。When the index of the CQI is less than 16, the mapping table actually used may be part of any of the above Tables 1-32. When the index of the CQI is greater than 16, any one of the above tables 1 to 32 may be part of the mapping table actually used. Of course, the index number of the CQI may also change accordingly.
2、编码方式包括LDPC BG2和Polar。2. The coding method includes LDPC BG2 and Polar.
本节也可以对映射表做一些调整，将调制方式与编码方式直接对应起来，便于工程使用，例如，调制阶数为2的QPSK都使用Polar，而调制阶数为4的16QAM和调制阶数为6的64QAM使用LDPC BG2，即以下所有调整后的表格(序号为32+2x的表格，其中x为大于1的整数)。也可以说，调整映射表的思路是调制阶数的取值与编码方式具有映射关系。在这些调整后的CQI映射表格中，甚至不需要再出现编码方式这一列，而根据调制阶数直接确定，这是一种隐式的指示，当然，这些调整也会影响到频谱效率和码率，具体可参见各表格。当然，也可以采用其他对应，比如64QAM用polar，而QPSK和16QAM用LDPC BG2，这里不作限制。This section can also make some adjustments to the mapping table, which directly corresponds to the modulation mode and the coding mode, which is convenient for engineering use. For example, QPSK with modulation order of 2 uses Polar, and modulation order of 4 is 16QAM and modulation order. LDPC BG2 is used for 6 64QAM, ie all the following adjusted tables (tables with serial number 32+2x, where x is an integer greater than 1). It can also be said that the idea of adjusting the mapping table is that the value of the modulation order has a mapping relationship with the encoding mode. In these adjusted CQI mapping tables, even the column of encoding mode does not need to appear again, and it is an implicit indication based on the modulation order. Of course, these adjustments also affect the spectral efficiency and bit rate. For details, please refer to the tables. Of course, other correspondences may also be used, such as polar for 64QAM and LDPC BG2 for QPSK and 16QAM, which are not limited herein.
