Technical Field

本申请属于无线通信技术领域，具体涉及一种信源编码方法、装置、通信设备及可读存储介质。The present application belongs to the field of wireless communication technology, and specifically relates to a source coding method, device, communication equipment and readable storage medium.

Background Art

数据是移动网络的核心要素之一。用户设备(User Equipment,UE，也称为终端)、无线接入网和核心网可以产生海量数据。该些数据，除了用户面数据之外还有大量的移动网络内部数据，例如第六代移动通信技术(6th Generation Mobile Communication Technology，6G)系统的终端或者基站设备在发射无线电波进行通信的同时，还可以对接收信号进行测量，从而对电波传播环境及其中的目标物体进行无线感知，得到目标物体的位置、速度、方向、材质、成像等感知数据，从而支持丰富的感知应用和场景。同时，随着第五代移动通信技术(5th Generation Mobile Communication Technology，5G)网络人工智能(Artificial Intelligence，AI)用例(如信道状态信息(Channel State Information，CSI)反馈，波束管理和定位，用户行为预测等的AI模型)的研究，AI模型训练需要大量移动网络内部数据，小到几十K字节大到几百M字节的AI模型也需要在UE、无线接入网和核心网间传输。6G作为一个泛在联接的系统，在支撑物理与数字世界连接的过程中，会产生大量有价值的基础数据信息。相比5G仅提供UE定位和网络信息开放等有限的数据服务，6G将提供无线感知与定位，增强网络信息开放。此外，6G还可以收集各类传感器信息和地理信息系统(Geographic Information System，GIS)信息等行业公共信息，赋能千行百业，以避免各行业应用对该类数据的重复收集。Data is one of the core elements of mobile networks. User equipment (UE, also known as terminals), wireless access networks and core networks can generate massive amounts of data. In addition to user-side data, these data also include a large amount of mobile network internal data. For example, the terminals or base station equipment of the 6th Generation Mobile Communication Technology (6G) system can measure the received signals while transmitting radio waves for communication, thereby wirelessly sensing the radio wave propagation environment and the target objects therein, and obtaining the target object's position, speed, direction, material, imaging and other perception data, thereby supporting a variety of perception applications and scenarios. At the same time, with the research on artificial intelligence (AI) use cases in the fifth generation mobile communication technology (5G) network (such as channel state information (CSI) feedback, beam management and positioning, user behavior prediction and other AI models), AI model training requires a large amount of mobile network internal data, and AI models ranging from tens of K bytes to hundreds of M bytes also need to be transmitted between UE, wireless access network and core network. As a ubiquitous connection system, 6G will generate a large amount of valuable basic data information in the process of supporting the connection between the physical and digital worlds. Compared with 5G, which only provides limited data services such as UE positioning and network information opening, 6G will provide wireless perception and positioning to enhance network information opening. In addition, 6G can also collect industry public information such as various sensor information and geographic information system (GIS) information, empowering thousands of industries to avoid repeated collection of such data by various industry applications.

因此，随着前述UE、无线接入网和核心网的网络功能所产生的移动网络内部数据增多，各个功能之间相互收集和消费数据的传输资源开销也随之增加。Therefore, as the internal data of the mobile network generated by the network functions of the aforementioned UE, radio access network and core network increases, the transmission resource overhead for collecting and consuming data between the various functions also increases.

为了解决存储资源和传输资源短缺，需要考虑支持移动网络内部数据的信源编码方法，从而节省存储资源和传输资源。In order to solve the shortage of storage resources and transmission resources, it is necessary to consider a source coding method that supports data within the mobile network, thereby saving storage resources and transmission resources.

下面对本申请涉及的技术内容进行说明。The technical contents involved in this application are explained below.

(1)鲁棒头压缩(RObust Header Compression，ROHC)(1) Robust Header Compression (ROHC)

ROHC是一种压缩各种因特网(互联网)协议(Internet Protocol，IP)数据包报头的算法。在IPv4中，未压缩的IP包头大小为40字节，而在IPv6中，未压缩的IP包头大小为60字节。如果是普通的数据包应用(如文件传输或浏览)，这并不是一个大问题，因为传输数据的大小与报头的大小相比是非常大的。因此，IP报头产生的开销并不是一个大问题。但在某些应用(如互联网电话(Voice over Internet Protocol，VoIP)、短信息、游戏等)中，传输的数据量往往很小，而且会产生非常频繁的交易，在这种情况下，IP报头产生的开销就会非常大。在这种情况下，如果能想出任何方法来减少IP报头的大小，那将是非常有益的，而ROHC就是RFC 3095中定义的方法之一。ROHC的理想压缩率是将报头的大小(原始大小为40或60字节)减小到只有1或2字节。ROHC is an algorithm for compressing the headers of various Internet Protocol (IP) packets. In IPv4, the size of the uncompressed IP header is 40 bytes, while in IPv6, the size of the uncompressed IP header is 60 bytes. This is not a big problem for normal packet applications such as file transfer or browsing, because the size of the data being transferred is very large compared to the size of the header. Therefore, the overhead generated by the IP header is not a big problem. But in some applications such as Voice over Internet Protocol (VoIP), SMS, gaming, etc., the amount of data transferred tends to be small and very frequent transactions occur, in which case the overhead generated by the IP header becomes very large. In such cases, it would be very beneficial if any method could be devised to reduce the size of the IP header, and ROHC is one of the methods defined in RFC 3095. The ideal compression ratio for ROHC is to reduce the size of the header (original size is 40 or 60 bytes) to only 1 or 2 bytes.

ROHC功能实体位于UE和eNodeB/gNB的用户面分组数据汇聚协议(packet Date Convergence Protocol，PDCP)实体中，仅仅用于用户面数据包的头压缩和解压。也就是说ROHC主要面向移动网络承载的来自移动网络外部的用户数据，对用户数据包进行包头压缩。The ROHC functional entity is located in the user-plane packet data convergence protocol (PDCP) entity of the UE and eNodeB/gNB, and is only used for header compression and decompression of user-plane data packets. In other words, ROHC is mainly for user data from outside the mobile network carried by the mobile network, and performs header compression on user data packets.

UDC协议基于IETF RFC 1951(DEFLATE压缩数据格式规范)。DEFLATE压缩策略采用IETF RFC 1951中定义的静态哈夫曼编码树。UDC数据块应采用字节对齐方式。采用Z_SYNC_FLUSH作为DEFLATE字节对齐方式，在传输前删除固定的最后四个字节0x00 0x00 0xFF 0xFF。The UDC protocol is based on IETF RFC 1951 (DEFLATE compressed data format specification). The DEFLATE compression strategy uses the static Huffman coding tree defined in IETF RFC 1951. UDC data blocks should be byte aligned. Z_SYNC_FLUSH is used as the DEFLATE byte alignment, and the fixed last four bytes 0x00 0x00 0xFF 0xFF are deleted before transmission.

与数据无线承载(Data Radio Bearer，DRB)相关的PDCP实体可由上层配置为使用UDC。如果配置了UDC，则UE应应用UDC压缩功能来处理从上层接收到的与配置的DRB相对应的PDCP服务数据单元(Service Data Unit，SDU)。如果上层配置了预定义字典，则UE应在配置UDC时在压缩缓冲器中预填配置的预定义字典。如果上层未配置预定义字典，则UE应将压缩缓冲区设置为全零。PDCP entities associated with Data Radio Bearers (DRBs) may be configured by upper layers to use UDC. If UDC is configured, the UE shall apply UDC compression to PDCP Service Data Units (SDUs) received from upper layers corresponding to the configured DRBs. If upper layers configure predefined dictionaries, the UE shall prefill the compression buffer with the configured predefined dictionaries when UDC is configured. If upper layers do not configure predefined dictionaries, the UE shall set the compression buffer to all zeros.

可以发现，UDC功能实体位于UE和eNodeB/gNB的用户面PDCP实体中，仅仅用于用户面数据包的压缩和解压缩。也就是UDC主要面向移动网络承载的来自移动网络外部的用户数据，对用户数据包进行压缩。并且，每个承载用户面数据的PDCP实体要么使用UDC，要么使用ROHC，二者不同时使用。It can be found that the UDC functional entity is located in the user plane PDCP entity of the UE and eNodeB/gNB, and is only used for compression and decompression of user plane data packets. That is, UDC is mainly for user data from outside the mobile network carried by the mobile network, and compresses the user data packets. In addition, each PDCP entity that carries user plane data uses either UDC or ROHC, and the two are not used at the same time.

(3)数据面(Data Plane)(3) Data Plane

目前6G网络架构讨论中，业界多家公司提出了数据面。数据面由核心网数据面功能、无线接入网数据面功能和UE数据面功能组成，具备端到端的连通性。数据面负责数据控制，包括数据收集协调、数据收集配置和数据传输配置等。数据面还负责数据采集、数据传输、数据预处理、数据隐私安全、数据分析、数据存储和数据服务等功能中的至少一项。In the current discussion of 6G network architecture, many companies in the industry have proposed the data plane. The data plane consists of core network data plane functions, radio access network data plane functions, and UE data plane functions, and has end-to-end connectivity. The data plane is responsible for data control, including data collection coordination, data collection configuration, and data transmission configuration. The data plane is also responsible for at least one of the functions of data collection, data transmission, data preprocessing, data privacy and security, data analysis, data storage, and data services.

(4)信源编解码(4) Source Encoding and Decoding

信源编解码基本的通信模型如下：信源(source)->信源编码器(source encoder)->信道编码器(channelencoder)->信道(channel)->信道解码器(source decoder)->信源解码器(channel decoder)->信宿(destination)。The basic communication model of source encoding and decoding is as follows: source -> source encoder -> channel encoder -> channel -> channel decoder -> source decoder -> source decoder -> destination.

其中，信源(source)，为发出信息的载体。这里默认输出二进制数。The source is the carrier of information. The default output here is binary.

信源编码器(source encoder)，对信源的输出进行无损编码(或者进行符合要求的有损编码)，目的是减少信源输出信息的冗余。可以理解为压缩。The source encoder performs lossless encoding (or lossy encoding that meets the requirements) on the output of the source, with the aim of reducing the redundancy of the source output information. This can be understood as compression.

信道编码器(channelencoder)，对信源编码器的输出进行编码，使得到的序列能够较好地在信道中传输。一般会增加冗余来增强抗干扰性。The channel encoder encodes the output of the source encoder so that the resulting sequence can be transmitted better in the channel. Generally, redundancy is added to enhance anti-interference.

信道(channel)，信息在信道中传输，发给接收端。Channel: Information is transmitted in the channel and sent to the receiving end.

信道解码器(channeldecoder)，对接收的序列进行解码，可以恢复一定的传输错误。The channel decoder decodes the received sequence and can recover certain transmission errors.

信源解码器(source decoder)，对信道解码器的输出进行解码，恢复原始的信息序列。The source decoder decodes the output of the channel decoder and restores the original information sequence.

信宿(destination)，需要原始信息的载体。The destination requires a carrier of the original information.

Please refer to Figure 3, which is a schematic diagram of the data plane protocol architecture of the UE, the wireless access network and the core network.

所谓信源编码是一种以提高通信有效性为目的而对信源符号进行的变换，或者说为了减少或消除信源冗余度而进行的信源符号变换，可以达到减少信源符号的大小的效果，因此信源编码也可以称为数据压缩。The so-called source coding is a transformation of source symbols for the purpose of improving communication effectiveness, or in other words, a transformation of source symbols to reduce or eliminate source redundancy. It can achieve the effect of reducing the size of source symbols, so source coding can also be called data compression.

For example, an AI model generated by an application server or application function outside the mobile network is sent to the UE, radio access network equipment or core network equipment, and the corresponding equipment needs to deploy and use the AI model.

上述移动网络内容数据涉及的终端(UE)是指3GPP协议定义的用户设备(User equipment)的协议功能，不包括应用功能。The terminal (UE) involved in the above-mentioned mobile network content data refers to the protocol functions of the user equipment (User equipment) defined by the 3GPP protocol, excluding application functions.

举例来说，移动网络内部数据可以包括以下至少一项：感知数据、定位数据、AI模型和AI模型训练数据。For example, the mobile network internal data may include at least one of the following: perception data, positioning data, AI model, and AI model training data.

一些实施例中，可选地，第一通信设备向第二通信设备发送第一数据包，所述第一数据包包括信源编码头部，所述信源编码头部包括第一指示信息，所述第一指示信息用于指示所述第一数据包是否被信源编码。第二通信设备接收到所述第一数据包之后，可以根据所述信源编码头部，确定所述第一数据包是否被信源编码，在确定第一数据包被信源编码的情况下，执行信源解码。本申请实施例中，所述第一通信设备可以是数据提供者，也可以称为数据提供功能，可以是UE、无线接入网设备或核心网设备。所述第二通信设备可以是数据消费者，也可以称为数据消费功能。或者，所述第二通信设备也可以是数据面功能节点，数据提供者所提供的数据经数据面功能节点提供给数据消费者。其中，数据面功能节点可以提供数据提供者所提供的原始数据，或者提供经过处理后的数据。第二通信设备可以是UE、无线接入网设备或核心网设备。In some embodiments, optionally, a first communication device sends a first data packet to a second communication device, the first data packet includes a source coding header, the source coding header includes first indication information, and the first indication information is used to indicate whether the first data packet is source coded. After receiving the first data packet, the second communication device can determine whether the first data packet is source coded according to the source coding header, and perform source decoding when it is determined that the first data packet is source coded. In an embodiment of the present application, the first communication device may be a data provider, which may also be referred to as a data provision function, and may be a UE, a wireless access network device, or a core network device. The second communication device may be a data consumer, which may also be referred to as a data consumption function. Alternatively, the second communication device may also be a data plane function node, and the data provided by the data provider is provided to the data consumer via the data plane function node. Among them, the data plane function node may provide the original data provided by the data provider, or provide processed data. The second communication device may be a UE, a wireless access network device, or a core network device.

本申请实施例中，第一指示信息可以是显式指示所述第一数据包是否被信源编码，也可以通过隐式指示的方式指示所述第一数据包是否被信源编码，例如所述第一指示信息指示所述第一数据包的数据类型是数据面的控制信息，则隐式指示第一数据包没有被信源编码，所述第一指示信息指示所述第一数据包的数据类型是数据面的数据信息，则隐式指示第一数据包被信源编码。In an embodiment of the present application, the first indication information may be an explicit indication of whether the first data packet is source encoded, or may be an implicit indication of whether the first data packet is source encoded. For example, if the first indication information indicates that the data type of the first data packet is control information on the data plane, it implicitly indicates that the first data packet is not source encoded; if the first indication information indicates that the data type of the first data packet is data information on the data plane, it implicitly indicates that the first data packet is source encoded.

本申请实施例中，可选地，所述信源编码头部还包括以下至少一项：In the embodiment of the present application, optionally, the source coding header further includes at least one of the following:

1)数据类型；例如可以是现有协议中的traceID，也可以是数据收集的任务标识等。也可以是数据面的控制信息，或者数据面的数据信息等。1) Data type: for example, it can be a traceID in an existing protocol, or a task identifier for data collection, etc. It can also be control information on the data plane, or data information on the data plane, etc.

2)第二指示信息，用于指示所述第一数据包被有损信源编码或者被无损信源编码；2) second indication information, used to indicate whether the first data packet is encoded by a lossy source or by a lossless source;

由于信源编码编码面向移动网络内部数据而非用户面数据，因此可根据数据的应用场景和对数据质量的需求等对第一数据包采用合适的信源编码，而不需要局限于无损信源编码算法。Since source coding is for mobile network internal data rather than user plane data, appropriate source coding can be used for the first data packet according to the application scenario of the data and the requirements for data quality, without being limited to lossless source coding algorithms.

3)第三指示信息，用于指示信源编码缓冲区是否重置；3) third indication information, used to indicate whether the source encoding buffer is reset;

所述第三指示信息指示所述第一通信设备的信源编码缓冲区是否重置。The third indication information indicates whether the source coding buffer of the first communication device is reset.

4)所述第一数据包使用的信源编码算法或算法标识；该信源编码算法可以包括以下至少一项：协议中预定义的算法，预部署算法。4) A source coding algorithm or algorithm identifier used by the first data packet; the source coding algorithm may include at least one of the following: an algorithm predefined in the protocol, a pre-deployed algorithm.

5)校验位，用于校验所述第一数据包的信源编码和解码的正确性；校验对象可以是单个信源编码的数据包，例如信源编码端对信源编码前的数据通过校验算法(例如奇偶校验)产生校验比特(校验位)，接收端接收到该数据包后进行信源解码，解码后的数据用同样校验算法产生校验比特。如果与接收到的编码端的校验比特一致，则认为信源编解码正确，否则错误。5) Check bits, used to check the correctness of the source coding and decoding of the first data packet; the check object can be a single source coded data packet, for example, the source coding end generates check bits (check bits) for the data before source coding through a check algorithm (such as parity check), and the receiving end performs source decoding after receiving the data packet, and generates check bits for the decoded data using the same check algorithm. If the check bits are consistent with the received coding end, the source coding and decoding is considered correct, otherwise it is wrong.

本申请实施例中，所述校验位是第一通信设备对第一数据包对应的编码前的数据通过In the embodiment of the present application, the check bit is the first communication device checking the data before encoding corresponding to the first data packet.

校验算法产生的。此时，接收到的第一数据包的第二通信设备对第一数据包进行信源解码，解码后的数据用同样的校验算法产生校验位，与接收到的校验位进行比较，如果与接收到的校验位一致，则认为信源编解码正确，否则错误。At this time, the second communication device that receives the first data packet performs source decoding on the first data packet, and uses the same verification algorithm to generate a check bit for the decoded data, which is compared with the received check bit. If it is consistent with the received check bit, it is considered that the source encoding and decoding is correct, otherwise it is wrong.

6)反馈信息，用于指示对所述第一通信设备接收到的信源编码数据的信源解码是否正确；6) feedback information, used to indicate whether source decoding of source coded data received by the first communication device is correct;

当信源编码数据的接收端发生解码错误或数据包丢失时，通过该反馈信息上报错误。此时，反馈信息的作用主要是提供信源编码反馈，供信源编码数据的发送端确定是否需要调整信源编码参数。其中，信源编码参数调整可以包括对所使用的信源编码的参数进行调整，例如压缩率等，也可以包括更换信源编码算法。在每个数据包可以独立使用信源编码的情况下，如果少量数据包解码错误对所述第一数据的使用无影响，那么可以不做重新传输处理或调整信源编码参数。如果发送端判断解码错误对数据使用有影响，一种方式是当收到信源解码错误时调整压缩率，即保留更多的数据。这一过程可以采用统一信源编码算法或更改信源编码算法，同时还需要重置信源编码缓冲区。所述压缩率的定义可以包括以下之一：信源编码后的数据长度除以信源编码前的数据长度，信源编码前的数据长度除以信源编码后的数据长度，1-信源编码后的数据长度/信源编码前的数据长度。When a decoding error or data packet loss occurs at the receiving end of the source coded data, the error is reported through the feedback information. At this time, the role of the feedback information is mainly to provide source coding feedback for the sending end of the source coded data to determine whether the source coding parameters need to be adjusted. Among them, the source coding parameter adjustment may include adjusting the parameters of the source coding used, such as the compression rate, etc., and may also include changing the source coding algorithm. In the case where each data packet can use source coding independently, if a small number of data packet decoding errors have no effect on the use of the first data, then no retransmission processing or adjustment of the source coding parameters may be performed. If the sending end determines that the decoding error has an impact on the use of the data, one way is to adjust the compression rate when a source decoding error is received, that is, to retain more data. This process can use a unified source coding algorithm or change the source coding algorithm, and it is also necessary to reset the source coding buffer. The definition of the compression rate may include one of the following: the data length after source coding divided by the data length before source coding, the data length before source coding divided by the data length after source coding, 1-the data length after source coding/the data length before source coding.

当第一通信设备接收经过信源编码的数据时，可以根据协议定义的校验算法阐述信源解码数据的校验位，并与接收到的校验位进行比较，判断信源解码是否正确。如果错误，并且需要发送上述经过信源编码的数据的发送端知道时，可以发送上述反馈信息。如果正确或者无需发送端知道解码正确与否的情况下，为了减少开销也可以不发送反馈信息，例如默认没有反馈的情况下是解码正确。When the first communication device receives source-coded data, it can interpret the check bit of the source-decoded data according to the check algorithm defined in the protocol, and compare it with the received check bit to determine whether the source decoding is correct. If it is wrong, and the sender that needs to send the above-mentioned source-coded data knows it, the above-mentioned feedback information can be sent. If it is correct or the sender does not need to know whether the decoding is correct or not, in order to reduce overhead, feedback information may not be sent, for example, the decoding is correct by default when there is no feedback.

7)第四指示信息，用于指示所述第一数据包为经过信源编码的待传输数据；7) fourth indication information, used to indicate that the first data packet is source-coded data to be transmitted;

也就是说，当第一指示信息指示第一数据包被信源编码的情况下，通过所述第四指示信息指示第一数据包为对待传输数据本身进行信源编码得到的数据包。That is, when the first indication information indicates that the first data packet is source encoded, the fourth indication information indicates that the first data packet is a data packet obtained by performing source encoding on the data to be transmitted itself.

8)第五指示信息，用于指示所述第一数据包是对所述第一通信设备接收到的信源编码数据的解码结果进行反馈的数据包；8) fifth indication information, used to indicate that the first data packet is a data packet for providing feedback on a decoding result of source coded data received by the first communication device;

也就是说，当第一指示信息指示第一数据包被信源编码的情况下，通过所述第五指示信息指示第一数据包为用于反馈的数据包。That is, when the first indication information indicates that the first data packet is source encoded, the fifth indication information indicates that the first data packet is a data packet for feedback.

9)第六指示信息，用于指示所述第一数据包为信源编码的起始数据包或者结束数据包，其中，所述起始数据包和结束数据包之间的数据包采用相同的信源编码方式；9) sixth indication information, used to indicate that the first data packet is a start data packet or an end data packet of source coding, wherein the data packets between the start data packet and the end data packet adopt the same source coding mode;

10)第一序号，所述第一序号为所述第一数据包的序号；10) a first sequence number, wherein the first sequence number is a sequence number of the first data packet;

11)第二序号，所述第二序号为反馈信息对应的信源编码数据的序号，所述反馈信息用于指示对所述第一通信设备接收到的信源编码数据的信源解码是否正确。11) A second sequence number, where the second sequence number is the sequence number of the source coded data corresponding to the feedback information, and the feedback information is used to indicate whether the source decoding of the source coded data received by the first communication device is correct.

本申请实施例中，可选地，所述第一数据包为信源编码的起始数据包或者结束数据包，所述方法还包括：所述第一通信设备发送第二数据包，所述第二数据包为信源编码的起始数据包和结束数据包之间的数据包，所述第二数据包不包括以下至少一项：In an embodiment of the present application, optionally, the first data packet is a start data packet or an end data packet of source coding, and the method further includes: the first communication device sends a second data packet, the second data packet is a data packet between the start data packet and the end data packet of source coding, and the second data packet does not include at least one of the following:

可以理解的是，所述开始数据包和所述结束数据包之间的第二数据包可以采用与第一数据包同样的信源编码方式，可以称其具有数据包亲和性。这样序列号介于开始和结束数据包序列号之间的第二数据包就无需信源编码头部的至少部分信息，从而节省信源编码头部的开销。It is understandable that the second data packet between the start data packet and the end data packet can use the same source coding method as the first data packet, which can be said to have data packet affinity. In this way, the second data packet with a sequence number between the sequence numbers of the start and end data packets does not need at least part of the information of the source coding header, thereby saving the overhead of the source coding header.

本申请实施例中，可选地，所述第一数据包包括以下至少一项：数据面的控制信息对应的数据包、数据面的数据信息对应的数据包和控制面的数据包。In an embodiment of the present application, optionally, the first data packet includes at least one of the following: a data packet corresponding to control information on the data plane, a data packet corresponding to data information on the data plane, and a data packet on the control plane.

本申请实施例中，所述校验位是发送所述第一数据包的第一通信设备对第一数据包对应的编码前的数据通过校验算法产生的。此时，所述第二通信设备对接收到的第一数据包进行信源解码，解码后的数据用同样的校验算法产生校验位，与接收到的校验位进行比较，如果与接收到的校验位一致，则认为信源编解码正确，否则错误。In the embodiment of the present application, the check bit is generated by the first communication device that sends the first data packet using a check algorithm for the data before encoding corresponding to the first data packet.

For examples of the lossy source coding algorithm and the lossless source coding algorithm, see the description of the embodiment shown in FIG. 4 .

下面结合具体实施例，对本申请实施例的信源编码方法举例进行说明。The source coding method of the embodiment of the present application is described below with reference to specific embodiments.

实施例1：Embodiment 1:

本实施例中，支持每数据包灵活使用信源编码的方法。In this embodiment, a method of flexibly using source coding for each data packet is supported.

本实施例阐述数据面协议栈支持信源编码的方法。将数据面协议栈对应的协议层称为第一子层，可以参见图2所示的终结在无线接入网的数据面协议架构的数据面协议栈示意图。下面实施例将所述第一子层称为数据面应用协议(Data Plane Application Protocol，DPAP)，也可以是其它名称，如数据服务应用协议(DataServiceApplication Protocol，DSAP))等。This embodiment describes a method for the data plane protocol stack to support source coding. The protocol layer corresponding to the data plane protocol stack is called the first sublayer. Please refer to the data plane protocol stack schematic diagram of the data plane protocol architecture terminated in the wireless access network shown in Figure 2. In the following embodiments, the first sublayer is called the Data Plane Application Protocol (DPAP), or other names, such as Data Service Application Protocol (DSAP).

由于数据面的主要用途是用于传输移动网络内部的大量数据，因此本实施例假设支持数据面的节点(UE、无线接入网设备、核心网设备)均支持信源编码，即信源编码是数据面承载的功能之一。Since the main purpose of the data plane is to transmit large amounts of data within the mobile network, this embodiment assumes that all nodes supporting the data plane (UE, wireless access network equipment, core network equipment) support source coding, that is, source coding is one of the functions carried by the data plane.

本实施例中，第一通信设备是UE，UE发送第一数据包。In this embodiment, the first communication device is a UE, and the UE sends a first data packet.

本申请实施例中的信源编码方法包括以下步骤：The source coding method in the embodiment of the present application comprises the following steps:

首先，UE发送UE能力信息给网络侧设备，UE能力信息包括UE的信源编码能力信息。本步骤为可选步骤。假设协议定义UE和网络都是支持信源编码的，则UE无需上报UE的信源编码能力信息。First, the UE sends UE capability information to the network side device, and the UE capability information includes the UE's source coding capability information. This step is optional. Assuming that the protocol defines that both the UE and the network support source coding, the UE does not need to report the UE's source coding capability information.

所述信源编码能力信息可以包括以下至少一项：The source coding capability information may include at least one of the following:

标准的信源编码算法可以包括有损信源编码算法和无损信源编码算法中的至少一项。有损信源编码算法和无损信源编码算法的例子可以参见上述实施例中的说明，不再赘述。The standard source coding algorithm may include at least one of a lossy source coding algorithm and a lossless source coding algorithm. Examples of the lossy source coding algorithm and the lossless source coding algorithm can be found in the description of the above embodiment and will not be described in detail.

因为本申请面向移动网络内部数据进行信源编码，因此运营商可以根据所收集和传输的数据的应用场景定义信源编码算法。类似于上述聚焦于某一类数据的有损信源编码，运营商定义的信源编码算法有望进一步降低数据传输量。考虑UE可能是不同运营商多卡等情况，对于运营商定义的信源编码算法需指示算法版本信息和对应的PLMN标识。Because this application performs source coding on data within the mobile network, the operator can define the source coding algorithm based on the application scenario of the collected and transmitted data. Similar to the above-mentioned lossy source coding that focuses on a certain type of data, the source coding algorithm defined by the operator is expected to further reduce the amount of data transmitted. Considering that the UE may have multiple cards from different operators, the algorithm version information and the corresponding PLMN identifier must be indicated for the source coding algorithm defined by the operator.

下面对UE和网络侧基于信源编码头部的交互的流程简述如下：The following is a brief description of the interaction process between the UE and the network side based on the source coding header:

步骤1：网络侧发送第二消息给UE，所述第二消息用于指示建立数据面承载。Step 1: The network side sends a second message to the UE, where the second message is used to indicate the establishment of a data plane bearer.

所述网络侧例如可以为无线接入网设备，所述第二消息例如可以是RRC信令。The network side may be, for example, a radio access network device, and the second message may be, for example, RRC signaling.

一种基于RRC信令的第二消息示例如下所示。
An example of a second message based on RRC signaling is shown below.

步骤2：UE接收第二消息，如果添加数据面承载，那么发送响应消息给网络侧。例如响应消息可以为RRCReconfigurationComplete消息。Step 2: The UE receives the second message, and if a data plane bearer is added, a response message is sent to the network side. For example, the response message may be an RRCReconfigurationComplete message.

步骤3：对所述数据面承载，UE使用信源编码头部产生DPAP层的服务数据单元(ServiceDataUnit，SDU)(即第一数据包)。Step 3: For the data plane bearer, the UE uses the source coding header to generate a service data unit (SDU) (ie, the first data packet) of the DPAP layer.

考虑数据面承载中可能传输数据面的控制信息和数据信息中的至少一项。因此，一种信源编码方案是根据数据需求确定每个第一数据包是否使用信源编码。例如对于数据面的控制信息(如数据收集配置)由于可以使用ASN.1等方式来采用较少的比特表示，因此控制信息可以不使用信源编码。对于数据面的数据信息(例如收集的数据或AI模型等)可以通过信源编码以减少数据量。Consider at least one of the control information and data information of the data plane that may be transmitted in the data plane bearer. Therefore, a source coding scheme is to determine whether each first data packet uses source coding according to data requirements. For example, for the control information of the data plane (such as data collection configuration), since ASN.1 and other methods can be used to use fewer bits to represent the control information, source coding may not be used. For the data information of the data plane (such as collected data or AI models, etc.), source coding can be used to reduce the amount of data.

一种信源编码头部的示例如图6所示。本实施例中，可以通过1比特(coding)来指示该第一数据包是否被信源编码。如果是前述的控制信息不使用信源编码和数据信息使用信源编码的情况下，那么也可以通过一个比特指示该数据包是控制信息还是数据信息，从而间接指示了是否被信源编码。An example of a source coding header is shown in FIG6. In this embodiment, one bit (coding) may be used to indicate whether the first data packet is source coded. If the aforementioned control information does not use source coding and the data information uses source coding, one bit may also be used to indicate whether the data packet is control information or data information, thereby indirectly indicating whether it is source coded.

另一种示例方法是：Another example method is:

1bitD/C域，用于指示第一数据包是控制信息还是数据信息；1 bit D/C field, used to indicate whether the first data packet is control information or data information;

1bit压缩指示域：第一数据包是否被信源编码；如果确定控制面不进行信源编码的话，压缩指示域仅应用于指示数据信息是否被信源编码。1-bit compression indication field: whether the first data packet is source encoded; if it is determined that the control plane does not perform source encoding, the compression indication field is only used to indicate whether the data information is source encoded.

如果信源编码头部中包括校验位，从而接收端能够基于校验位对第一数据包的信源编解码进行校验。第一通信设备可以根据所采用的校验算法确定校验位的长度，校验算法例如为奇偶校验算法等。请参考图7，图7中的信源编码头部的校验位为1比特(check bit)。If the source coding header includes a check bit, the receiving end can check the source coding of the first data packet based on the check bit. The first communication device can determine the length of the check bit according to the adopted check algorithm, such as a parity check algorithm. Please refer to FIG. 7, the check bit of the source coding header in FIG. 7 is 1 bit (check bit).

可选地，如果UE支持不止一种信源编码算法，那么信源编码头部还需要包括第一数据包使用的信源编码算法信息。信源编码头部一种示例如图8所示，本实施例中，在coding指示第一数据包被信源编码的情况下，信源编码头部携带L/N域以及算法域(Algorithm)。通过1比特(L/N)来指示是有损压缩算法还是无损压缩算法，通过2比特(Algorithm)来指示信源编码算法是协议定义的算法还是运营商定义的算法的标识。Optionally, if the UE supports more than one source coding algorithm, the source coding header also needs to include the source coding algorithm information used by the first data packet. An example of a source coding header is shown in Figure 8. In this embodiment, when coding indicates that the first data packet is source encoded, the source coding header carries the L/N domain and the algorithm domain (Algorithm). 1 bit (L/N) is used to indicate whether it is a lossy compression algorithm or a lossless compression algorithm, and 2 bits (Algorithm) are used to indicate whether the source coding algorithm is a protocol-defined algorithm or an operator-defined algorithm.

可选的，还可以通过信源编码头部指示信源编码缓冲区是否重置。如果信源编码数据的发送端(UE)也接收了对端的信源编码数据时，那么可选的，可以在发送信源编码数据的同时反馈所接收数据的信源解码是否正确。即信源编码头部还用于指示对接收到的信源编码数据的信源解码是否正确。一种示例如下图所示，通过1比特(BuffR)指示信源编码缓冲区是否重置，通过1比特(ACK/NACK)指示对接收到的信源编码数据的信源解码是否正确。Optionally, the source coding header may also be used to indicate whether the source coding buffer is reset. If the sender (UE) of the source coded data also receives the source coded data from the other end, then optionally, it may be possible to provide feedback on whether the source decoding of the received data is correct while sending the source coded data. That is, the source coding header is also used to indicate whether the source decoding of the received source coded data is correct. An example is shown in the figure below, where 1 bit (BuffR) is used to indicate whether the source coding buffer is reset, and 1 bit (ACK/NACK) is used to indicate whether the source decoding of the received source coded data is correct.

为了避免乱序引起的问题，可选的，还可以定义DPAP层序号(第一序号)，例如图9中的6比特的DPAPSN字段，所述DPAPSN用于指示该协议数据单元(第一数据包)的序号。In order to avoid problems caused by disorder, optionally, a DPAP layer sequence number (first sequence number) may be defined, such as the 6-bit DPAPSN field in FIG. 9 , where the DPAPSN is used to indicate the sequence number of the protocol data unit (first data packet).

可选的，考虑在信源编码和解码过程中，因信源编解码的正确性、所传输数据的精度需求变化、空口资源变化可能需要进行信源编码参数调整。其中，信源编码参数调整可以包括对所使用的信源编码的参数进行调整，例如压缩率等，也可以包括更换信源编码算法。所述信源编码头部的反馈信息(feedback)一种示例可通过1比特ACK/NACK指示对接收到的信源编码数据的信源解码是否正确。当信源编码数据的接收端(如UE或网络)发生解码错误或数据包丢失时，通过该比特上报错误。此时，ACK/NACK的作用主要是提供信源编码反馈，供信源编码数据的发送端确定是否需要调整信源编码参数。在每个数据包可以独立使用信源编码的情况下，如果少量数据包解码错误，可以不做处理。如果发送端判断解码错误对数据使用有影响，一种方式是当收到信源解码错误时调整压缩率，即保留更多的数据。这一过程可以采用统一信源编码算法或更改信源编码算法，同时还需要重置信源编码缓冲区。所述压缩率的定义可以包括以下之一：信源编码后的数据长度除以信源编码前的数据长度，信源编码前的数据长度除以信源编码后的数据长度，1-信源编码后的数据长度/信源编码前的数据长度。Optionally, it is considered that during the source coding and decoding process, source coding parameters may need to be adjusted due to the correctness of source coding and decoding, changes in the accuracy requirements of the transmitted data, and changes in air interface resources. Among them, the source coding parameter adjustment may include adjusting the parameters of the source coding used, such as compression rate, etc., and may also include changing the source coding algorithm. An example of the feedback information (feedback) of the source coding header may indicate whether the source decoding of the received source coded data is correct through 1 bit ACK/NACK. When a decoding error or data packet loss occurs at the receiving end (such as UE or network) of the source coded data, the error is reported through this bit. At this time, the role of ACK/NACK is mainly to provide source coding feedback for the sending end of the source coded data to determine whether the source coding parameters need to be adjusted. In the case where each data packet can use source coding independently, if a small number of data packets are decoded incorrectly, no processing is required. If the sending end determines that the decoding error has an impact on the use of data, one way is to adjust the compression rate when a source decoding error is received, that is, to retain more data. This process can use a unified source coding algorithm or change the source coding algorithm, and it is also necessary to reset the source coding buffer. The definition of the compression rate may include one of the following: the data length after source coding divided by the data length before source coding, the data length before source coding divided by the data length after source coding, 1-the data length after source coding/the data length before source coding.

如果根据ACK/NACK指示，当信源解码错误时，需要对解码错误的数据进行重传，那么还需要指示ACK或NACK对应哪一个序号的数据包，从而对NACK对应的数据包基于原信源编码算法重传或者更改信源编码参数后重新进行信源编码后再重传。一种信源编码头部的示例如下：通过Type指示当前数据包是信源编码数据或对接收到的信源编码数据的解码结果的反馈。请参考图10，当Type指示为对接收到的信源编码数据的解码结果的反馈时，除包括ACK/NACK外，还可以包括ACK/NAC对应的数据包序号的低5位(这里5仅是下方示例，可以是其它数值)。注意这里的SN是ACK/NACK对应的数据包的序号，与上述用于指示第一数据包的序号的DPAPSN不同。If, according to the ACK/NACK indication, when a source decoding error occurs, the decoded erroneous data needs to be retransmitted, then it is also necessary to indicate which data packet the ACK or NACK corresponds to, so that the data packet corresponding to the NACK is retransmitted based on the original source coding algorithm or the source coding parameters are changed and then re-source encoded before retransmission. An example of a source coding header is as follows: Type is used to indicate that the current data packet is source coded data or feedback on the decoding result of the received source coded data. Please refer to Figure 10. When the Type indication is feedback on the decoding result of the received source coded data, in addition to ACK/NACK, the lower 5 bits of the data packet sequence number corresponding to the ACK/NACK may also be included (here 5 is only an example below and can be other values). Note that the SN here is the sequence number of the data packet corresponding to the ACK/NACK, which is different from the DPAPSN used to indicate the sequence number of the first data packet mentioned above.

步骤4：网络侧接收UE发送的DPAPSDU(第一数据包)，并基于信源编码头部进行处理，获得数据。Step 4: The network side receives the DPAPSDU (first data packet) sent by the UE and processes it based on the source coding header to obtain data.

对于网络侧发送UE接收第一数据包的情况，也可以采用步骤3所述的信源编码头部。在这一过程中网络侧基于信源编码头部产生SDU，UE侧基于信源编码头部进行接收数据的信源解码。In the case where the network sends the first data packet and the UE receives the first data packet, the source coding header described in step 3 may also be used. In this process, the network generates an SDU based on the source coding header, and the UE performs source decoding on the received data based on the source coding header.

需要注意的是，本实施例中的各个步骤可以与上述信源编码方法对应的实施例结合。It should be noted that the various steps in this embodiment can be combined with the embodiments corresponding to the above-mentioned source coding method.

实施例2：Embodiment 2:

实施例1所述的方法的优势是灵活，可以每个数据包确定是否被信源编码，以及使用哪一种信源编码算法等。进一步考虑对信源编码头部开销和灵活性进行折中，实施例2提供了一种支持数据包亲和性的信源编码方法。The advantage of the method described in Example 1 is that it is flexible and can determine for each data packet whether to be source encoded and which source encoding algorithm to use, etc. Further considering the tradeoff between source encoding header overhead and flexibility, Example 2 provides a source encoding method that supports data packet affinity.

实施例2同样假设数据面的节点(UE、无线接入网设备、核心网设备)均支持信源编码，即信源编码是数据面承载的功能之一。Embodiment 2 also assumes that all nodes on the data plane (UE, wireless access network equipment, core network equipment) support source coding, that is, source coding is one of the functions carried by the data plane.

所述信源编码能力信息的参见实施例1中所述，不再赘述。The source coding capability information is described in Example 1 and will not be repeated here.

步骤3：对所述数据面承载，UE使用信源编码头部产生DPAP层的服务数据单元(ServiceDataUnit，SDU)(第一数据包或第二数据包)。Step 3: For the data plane bearer, the UE uses a source coding header to generate a service data unit (SDU) (first data packet or second data packet) of the DPAP layer.

考虑数据面承载的数据具有大数据量特征，因此通常一段时间内的数据如果使用信源编码，通常采用相同的信源编码方式。因此，一种信源编码头部的示例如图11所示：通过Type指示该数据包是信源编码起始或结束类型的数据包。当Type指示该数据包是信源编码起始或结束类型的数据包时，通过S/E的1比特指示是起始数据包还是结束数据数据包。假设该数据包是起始数据包，序号是M，那么UE发送序号为M+1数据包时就使用前述信源编码。类似地，假设该数据包是结束数据包，序号是N，那么UE发送序号为N+1数据包时就不再使用前述信源编码。因此起始数据包和结束数据包之间的数据包具有采用同样的信源编码方式，称其具有数据包亲和性。这样序号介于起始数据包和结束数据包序号之间的数据包(第二数据包)就无需信源编码头部，从而节省信源编码头部的开销。Considering that the data carried by the data plane has the characteristics of large data volume, if source coding is used for data within a period of time, the same source coding method is usually used. Therefore, an example of a source coding header is shown in Figure 11: Type is used to indicate that the data packet is a data packet of the start or end type of source coding. When Type indicates that the data packet is a data packet of the start or end type of source coding, 1 bit of S/E is used to indicate whether it is a start data packet or an end data packet. Assuming that the data packet is a start data packet and the sequence number is M, the UE uses the aforementioned source coding when sending a data packet with the sequence number M+1. Similarly, assuming that the data packet is an end data packet and the sequence number is N, the UE no longer uses the aforementioned source coding when sending a data packet with the sequence number N+1. Therefore, the data packets between the start data packet and the end data packet have the same source coding method, which is called data packet affinity. In this way, the data packet (the second data packet) with a sequence number between the start data packet and the end data packet sequence number does not need a source coding header, thereby saving the overhead of the source coding header.

可选的，对于需要信源编码头部的第一数据包，如果UE支持不止一种信源编码算法，那么信源编码头部还需要包括第一数据包使用的信源编码算法信息。信源编码头部一种示例如图11所示，本实施例中，信源编码头部携带L/N域以及算法域(Algorithm)。通过1比特(L/N)来指示是有损压缩算法还是无损压缩算法，通过2比特(Algorithm)来指示信源编码算法是协议定义的算法还是运营商定义的算法的标识。Optionally, for the first data packet that requires a source coding header, if the UE supports more than one source coding algorithm, the source coding header also needs to include the source coding algorithm information used by the first data packet. An example of a source coding header is shown in FIG11. In this embodiment, the source coding header carries an L/N domain and an algorithm domain (Algorithm). One bit (L/N) is used to indicate whether it is a lossy compression algorithm or a lossless compression algorithm, and two bits (Algorithm) are used to indicate whether the source coding algorithm is a protocol-defined algorithm or an operator-defined algorithm.

又例如，还可以通过信源编码头部指示数据包为控制信息或数据信息。其中控制信息的一种是指示起始或结束。类似的，控制起始和结束之间的数据信息根据前一个控制信息指示被信源编码和信源解码。一种示例如图12所示，采用1bitD/C域用于指示数据包为控制信息还是数据信息。所述控制信息表示该数据包仅包括信源编码相关的指示信息，数据信息表示该数据包包含被信源编码或未被信源编码的数据。当数据包为控制信息时，采用2bit Type域指示数据包的类型，例如是反馈信息，起始数据包还是结束数据包，或者，信源编码缓冲区是否重置。当通过Type指示该数据包是信源编码起始或结束类型的数据包时，通过S/E的1比特指示是起始数据包还是结束数据数据包。例如，S/E字段中当该比特为0的情况下表示是起始数据包(假设这个数据包序号SN为M)，那么这个数据包之后的数据包(即数据包序号为M+1及之后)则进行信源编码后传输。当收到该比特为1的情况下表示为结束数据包(假设这个数据包序号SN为N)，那么这个数据包之后的数据包(即数据包序号为N+1及之后)就不再使用信源编码。For another example, the source coding header may be used to indicate whether the data packet is control information or data information. One type of control information is to indicate the start or end. Similarly, the data information between the control start and end is source encoded and source decoded according to the previous control information indication. As shown in FIG. 12, an example is shown in which a 1-bit D/C field is used to indicate whether the data packet is control information or data information. The control information indicates that the data packet only includes indication information related to source coding, and the data information indicates that the data packet contains data that is source encoded or not source encoded. When the data packet is control information, a 2-bit Type field is used to indicate the type of the data packet, such as feedback information, a start data packet or an end data packet, or whether the source coding buffer is reset. When the Type field indicates that the data packet is a data packet of the source coding start or end type, a 1-bit S/E field indicates whether it is a start data packet or an end data packet. For example, when the bit in the S/E field is 0, it indicates that it is a start data packet (assuming that the data packet sequence number SN is M), then the data packets after this data packet (i.e., data packets with sequence numbers M+1 and later) are transmitted after source coding. When the received bit is 1, it indicates the end of the data packet (assuming that the data packet sequence number SN is N), then the data packets after this data packet (that is, data packets with sequence numbers N+1 and later) will no longer use source coding.

采用2bit Type域指示反馈信息，起始数据包还是结束数据包，以及，信源编码缓冲区是否重置。The 2-bit Type field is used to indicate feedback information, whether it is a start data packet or an end data packet, and whether the source encoding buffer is reset.

步骤4：网络侧接收UE发送的DPAPSDU，并基于DPAPSDU是否具有信源编码头部进行处理，获得数据。Step 4: The network side receives the DPAPSDU sent by the UE, and processes it based on whether the DPAPSDU has a source coding header to obtain data.

实施例3：联合信令承载或数据面承载配置的信源编码Embodiment 3: Source coding of joint signaling bearer or data plane bearer configuration

网络侧根据UE能力信息进行无线承载的增加、修改或释放。The network side adds, modifies or releases radio bearers based on the UE capability information.

下面对UE和网络侧进行信源编码相关交互的流程简述如下：The following is a brief description of the process of source coding interaction between the UE and the network side:

步骤1：网络侧发送第一消息给UE，所述第一消息包括：第七指示信息，所述第七指示信息用于指示第一数据是否使用信源编码，所述第一数据为移动网络内部数据。Step 1: The network side sends a first message to the UE, where the first message includes: seventh indication information, where the seventh indication information is used to indicate whether the first data uses source coding, and the first data is internal data of the mobile network.

对于无线接入网设备，既可以根据无线接入网的数据需求确定第一消息，也可以根据核心网发送的配置信息确定核心网所需数据对应的第一消息。For the wireless access network device, the first message may be determined according to the data requirement of the wireless access network, or the first message corresponding to the data required by the core network may be determined according to the configuration information sent by the core network.

可选地，所述配置信息包括以下至少一项：Optionally, the configuration information includes at least one of the following:

待传输数据的数据特征；Data characteristics of the data to be transmitted;

信源类型；Source type;

数据类型。Data type.

一种第一消息的示例是控制面的控制信令，所述控制信令通过信令无线承载(SignalingRadioBearer，SRB)传输，控制信令例如为RRC reconfiguration消息。例如，在当前的移动通信协议中，可以通过该消息增加、释放或修改DRB和SRB。当增加数据面时，类似地，也可以通过控制面信令增加、释放或修改数据面承载。所述第一消息指示信令承载(SRB)或数据面承载是否使用信源编码。An example of a first message is control signaling of a control plane, wherein the control signaling is transmitted via a signaling radio bearer (SRB), and the control signaling is, for example, an RRC reconfiguration message. For example, in the current mobile communication protocol, DRBs and SRBs can be added, released, or modified via this message. When a data plane is added, similarly, the data plane bearer can also be added, released, or modified via control plane signaling. The first message indicates whether a signaling bearer (SRB) or a data plane bearer uses source coding.

可选地，所述第七指示信息用于指示以下至少一项：Optionally, the seventh indication information is used to indicate at least one of the following:

可选地，所述第一消息还包括以下至少一项：Optionally, the first message further includes at least one of the following:

用于信源编码的缓冲区大小(buffer size)；The buffer size used for source encoding (buffer size);

步骤2：UE接收第一消息，如果添加数据面承载，那么发送响应消息给网络。例如响应消息例如为RRCReconfigurationComplete消息。Step 2: The UE receives the first message, and if a data plane bearer is added, sends a response message to the network, such as an RRCReconfigurationComplete message.

步骤3：UE基于第一消息中的信息，对映射到该承载传输的数据进行处理。考虑到该承载传输的数据有些需要信源编码，有些不需要。因此，UE基于信源编码头部执行发送数据和接收数据中的至少一项。Step 3: The UE processes the data mapped to the bearer transmission based on the information in the first message. Considering that some of the data in the bearer transmission requires source coding and some does not, the UE performs at least one of sending data and receiving data based on the source coding header.

针对需要进行信源编码的数据包，一种信源编码头部示例包括第一指示信息，所述第一指示信息用于指示数据包(第一数据包)是否被信源编码；可选的，信源编码头部还可以包括以下至少一项：For a data packet that needs to be source encoded, an example of a source encoding header includes first indication information, where the first indication information is used to indicate whether the data packet (first data packet) is source encoded; optionally, the source encoding header may also include at least one of the following:

数据类型；Data type;

第二指示信息，用于指示所述第一数据包被有损信源编码或者被无损信源编码；second indication information, used to indicate whether the first data packet is encoded by a lossy source or by a lossless source;

第四指示信息，用于指示所述第一数据包为经过信源编码的待传输数据；Fourth indication information, used to indicate that the first data packet is source-encoded data to be transmitted;

第五指示信息，用于指示所述第一数据包是对所述第一通信设备接收到的信源编码数据的解码结果进行反馈的数据包；fifth indication information, used to indicate that the first data packet is a data packet for feeding back a decoding result of source coded data received by the first communication device;

第六指示信息，用于指示所述第一数据包为信源编码的起始数据包或者结束数据包，其中，所述起始数据包和结束数据包之间的数据包采用相同的信源编码方式；Sixth indication information, used to indicate that the first data packet is a start data packet or an end data packet of source coding, wherein the data packets between the start data packet and the end data packet adopt the same source coding mode;

第一序号，所述第一序号为所述第一数据包的序号；A first sequence number, where the first sequence number is a sequence number of the first data packet;

第二序号，所述第二序号为反馈信息对应的信源编码数据的序号，所述反馈信息用于指示对所述第一通信设备接收到的信源编码数据的信源解码是否正确。A second sequence number, where the second sequence number is a sequence number of source coded data corresponding to feedback information, and the feedback information is used to indicate whether source decoding of the source coded data received by the first communication device is correct.

步骤4：可选的，如果信源编码头部包括校验位，那么当UE发送经过信源编码的数据时，还需要根据协议定义的校验算法产生校验位。UE可以发送所述校验位和经过信源编码的数据。Step 4: Optionally, if the source coding header includes a check bit, then when the UE sends the source coded data, it is also necessary to generate the check bit according to the check algorithm defined in the protocol. The UE can send the check bit and the source coded data.

类似的，当UE接收经过信源编码的数据时，需要根据协议定义的校验算法阐述信源解码数据的校验位，并与接收到的校验位进行比较，判断信源解码是否正确。如果错误，并且需要发送端知道时，发送上述反馈信息。如果正确或者无需发送端知道解码正确与否的情况下，为了减少开销也可以不发送反馈信息，例如默认没有反馈的情况下是解码正确。Similarly, when the UE receives source-encoded data, it is necessary to interpret the check bit of the source decoded data according to the check algorithm defined in the protocol, and compare it with the received check bit to determine whether the source decoding is correct. If it is wrong and the sender needs to know, the above feedback information is sent. If it is correct or the sender does not need to know whether the decoding is correct or not, in order to reduce overhead, the feedback information may not be sent, for example, the decoding is correct by default when there is no feedback.
