Technical Field

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

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.

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.

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.

The technical contents involved in this application are explained below.

(1) Robust Header Compression (ROHC)

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.

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.

(2) Uplink Data Compression (UDC)

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.

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.

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) Data Plane

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.

Please refer to Figure 2, which is a schematic diagram of the data plane protocol architecture terminated in the wireless access network. 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.

(4) Source Encoding and Decoding

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.

The source is the carrier of information. The default output here is binary.

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.

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.

Channel: Information is transmitted in the channel and sent to the receiving end.

The channel decoder decodes the received sequence and can recover certain transmission errors.

The source decoder decodes the output of the channel decoder and restores the original information sequence.

The destination requires a carrier of the original information.

The source coding method, apparatus, communication device and readable storage medium provided in the embodiments of the present application are described in detail below with reference to the accompanying drawings through some embodiments and their application scenarios.

Referring to FIG. 4 , an embodiment of the present application provides a source coding method, including:

Step 11: A first communication device receives a first message, wherein the first message includes: first indication information, wherein the first indication information is used to indicate whether the first data uses source coding; wherein the first data is internal data of a mobile network, and the internal data of the mobile network includes at least one of the following: sending and receiving data terminated at any two of a terminal, a wireless access network device, and a core network device, and sending or receiving data terminated at any one of a terminal, a wireless access network device, or a core network device.

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.

In some embodiments, optionally, the first communication device receives a first message sent by the second communication device.

In some embodiments of the present application, optionally, 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 UE, a wireless access network device, or a core network device.

In some embodiments of the present application, optionally, the first communication device may also be a data consumer, which may also be referred to as a data consumption function. Alternatively, the first 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 first communication device may be a UE, a wireless access network device, or a core network device. At this time, the first data is the data received by the first communication device. Optionally, the second 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.

In an embodiment of the present application, a first communication device receives first indication information, and the first support information is used to indicate whether the first data uses source coding, so that the first communication device can determine whether to perform source coding on the first data to be sent or to decode the received first data based on the first indication information, thereby supporting the source coding method of internal data of the mobile network and achieving the effect of saving storage resources and transmission resources.

The mobile network content data in the embodiment of the present application may also be referred to as non-user plane data, which may refer to data that can be parsed by UE, wireless access network or core network in the 3GPP standard. The mobile network internal data includes at least one of the following:

1) Send and receive data that terminates at any two of the terminals, wireless access network equipment, and core network equipment;

It can also be described as a peer-to-peer protocol for sending and receiving data located at the UE, radio access network or core network.

For example, the data of the peer protocol layers of the Long Term Evolution Positioning Protocol (LTE Positioning Protocol, LPP) are respectively located in the UE and the core network network function LMF (location management function); another example is the data of the peer protocol layers of the Radio Resource Control (Radio Resource Control, RRC) are respectively located in the UE and the wireless access network equipment (eNB/gNB, base station); another example is the data plane protocol layers are respectively located in the UE and the wireless access network equipment or in the UE and the core network equipment.

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.

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.

In the existing technical solutions, user-plane data transmitted over a mobile network can reduce the amount of data transmitted and improve transmission efficiency through Robust Header Compression (ROHC) or Uplink Data Compression (UDC). Since the existing solution is to compress user-plane data through the Packet Data Convergence Protocol (PDCP) layer of the Radio Access Network (RAN), the compression methods used by ROHC and UDC are both lossless compression, thereby avoiding affecting upper-layer applications. In the embodiment of the present application, since the data for source coding is internal data of the mobile network (non-user-plane data), the appropriate source coding can be determined based on the specific circumstances such as the application scenario of the data and the demand for data quality. It is not necessary to be limited to a lossless source coding algorithm, and a lossy source coding algorithm can also be used.

In the embodiment of the present application, optionally, when the second communication device sends the first data, the second communication device receives the third message. The source coding method of the embodiment of the present application is described below with reference to specific embodiments.

Embodiment 1:

In this embodiment, the first sublayer of the data plane supports source coding, and the first message is control signaling of the control plane.

This embodiment describes a method for supporting source coding in a data plane protocol stack. The protocol layer corresponding to the data plane protocol stack is called the first sublayer, and the schematic diagram of the data plane protocol stack of the data plane protocol architecture terminated in the wireless access network can be seen in FIG. 2 .

In this embodiment, the first communication device is a UE.

The source coding method in the embodiment of the present application comprises the following steps:

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.

If the first sublayer of the above data plane protocol stack is called a data plane application protocol (DataPlane Application Protocol, DPAP), an example of UE capability information can be as follows.

The source coding capability information of the UE is defined by the capability parameters of the data plane protocol layer. Among them, when SourceCodingsSupported is true, it means that the UE supports source coding, and supportedSourceCodingType is used to indicate support for at least one of lossy source coding and lossless source coding. supportedStandard-Profiles represents the standard source coding algorithm. The standard source coding algorithm may include at least one of a lossy source coding algorithm and a lossless source coding algorithm. Examples of lossy source coding algorithms and lossless source coding algorithms can be found in the description of the above embodiments and will not be repeated here.

supportedOperator-Profiles indicates the source coding algorithm defined by the operator. Because the data to be transmitted in the embodiment of the present application may be internal data of the mobile network, the operator can define the source coding algorithm according to 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 data transmission volume. Considering that the UE may have multiple cards of different operators, etc., the algorithm version information and the corresponding PLMN identifier must be indicated for the source coding algorithm defined by the operator.

The following is a brief description of the process of source coding-related interaction between the first communication device (UE) and the network side:

Step 1: The network side device sends a first message to the UE, and the first message includes: first indication information, and the first indication information is used to indicate whether the first data uses source coding; wherein the first data is internal data of the mobile network.

The network side device may be a wireless access network device, and the wireless access network device may determine the first message according to at least one of the following:

Data requirements;

Source coding capability information of the UE, the source coding capability information comprising third indication information, the third indication information being used to indicate whether the first communication device supports source coding;

Configuration information sent by core network devices.

In the embodiment of the present application, optionally, the data requirement includes at least one of the following:

The length of the data to be transmitted;

Real-time data transmission;

Data type;

The amount of available storage resources.

In the embodiment of the present application, optionally, the configuration information includes at least one of the following:

Terminal identification;

Terminal characteristics;

Indication information indicating whether the data to be transmitted uses source coding;

Indication information indicating that the data to be transmitted is applicable to at least one of lossy source coding and lossless source coding;

Data characteristics of the data to be transmitted;

Source type;

Data type.

An example of a first message is control signaling of a control plane, the control signaling being transmitted via a signaling radio bearer (SRB), the control signaling being, for example, an RRC reconfiguration message. For example, in current mobile communication protocols, data radio bearers (DRB) and SRB are two different bearer types, which are added via different information elements. The data plane bearer may be added, released, or modified via control plane signaling; then, in the addition, release, or modification of the data plane bearer, the first sublayer of the data plane protocol stack (such as DPAP) may be configured to indicate whether the first data uses source coding.

In the embodiment of the present application, optionally, the first indication information is used to indicate at least one of the following:

whether to use source coding for the first uplink data;

Whether to use source coding for the first downlink data.

In the embodiment of the present application, optionally, the first message further includes at least one of the following:

second indication information, used to indicate whether lossy source coding or lossless source coding is used for the first data;

The buffer size used for source encoding;

A source coding algorithm or an algorithm identifier used for the first data.

An example of sending the first message based on RRC signaling is as follows:

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.

Step 3: Based on the information in the first message, the UE processes the first data mapped to the data plane bearer transmission, including performing source encoding on the sent first data and/or performing source decoding on the received first data.

If source coding is used only in the uplink, the UE will perform source coding on the first data to be sent using the corresponding source coding algorithm according to the instruction. If source coding is used only in the downlink, the UE will perform source decoding when receiving the first data carried by the data plane. If source coding is used for both uplink and downlink, source coding is performed on the first data to be sent and source decoding is performed on the first data to be received.

Step 4: Optionally, if a check bit is used, when the UE sends source-coded data, it is also necessary to generate a check bit according to a check algorithm defined in the protocol. The UE sends the check bit and the source-coded data.

Similarly, when the UE receives source-coded data, it needs to interpret the check digit of the source decoded data according to the check algorithm defined in the protocol, and compare it with the received check digit to determine whether the source decoding is correct. If it is wrong and the sender needs to know, 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, feedback information may not be sent, for example, the default is that the decoding is correct when there is no feedback.

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.

Embodiment 2:

In this embodiment, the first sublayer of the data plane supports source coding, and the first message is a message of the data plane.

The difference between this embodiment and embodiment 1 is that the first message is a message transmitted by the data plane bearer, rather than the control plane signaling described in embodiment 1. The advantage of this embodiment is that the network side can configure whether to perform source coding and other configurations for the task according to the specific requirements of the data task. In other words, compared with embodiment 1, the granularity of the source coding configuration changes from per data plane bearer configuration to per data task configuration within the data plane bearer.

In this embodiment, the first communication device is a UE.

This embodiment describes a method for supporting source coding in a data plane protocol stack. The protocol layer corresponding to the data plane protocol stack is called the first sublayer. For a specific example, see the schematic diagram of the data plane protocol stack of the data plane protocol architecture terminated in the wireless access network shown in FIG3 .

The source coding method in the embodiment of the present application comprises the following steps:

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.

The UE capability information is the same as in Example 1 and will not be described again here.

The following is a brief description of the process of source coding interaction between the UE and the network side:

Step 1: The network side device sends a third message to the UE. An example of a third message is a message transmitted by the data plane bearer, rather than the control plane signaling. Among them, a method for adding, releasing and modifying the data plane bearer is as described in Example 1, that is, through RRC signaling. In this embodiment, the RRC signaling does not include information related to the DPAP layer source coding. RRC signaling is, for example, an RRC reconfiguration message. For example, in the current mobile communication protocol, DRB and SRB are two different bearer types, which are added through different information elements; the data plane bearer can be added, released or modified through control plane signaling; then in the addition, release or modification of the data plane bearer, the first sublayer of the data plane protocol stack (such as DPAP) can be configured to indicate whether the first data uses source coding.

Then, an example of a message for establishing a data plane bearer based on RRC signaling is as follows:

Step 2: The UE receives the third message, and if a data plane bearer is added, a message response message is sent to the network side device.

Step 3: The network side device sends a first message to the UE, where the first message includes: first indication information, where the first indication information is used to indicate whether the first data uses source coding; wherein the first data is internal data of the mobile network.

An example of a first message is a control message of a data plane, and the control message is transmitted through a data plane bearer.

In the embodiment of the present application, optionally, the first indication information is used to indicate at least one of the following:

whether to use source coding for the first uplink data;

Whether to use source coding for the first downlink data.

In the embodiment of the present application, optionally, the first message further includes at least one of the following:

A data task identifier, the data task identifier is used to indicate the first data. For example, the data task may be a data collection task (such as network collection and UE collection), and the data collection task identifier is X; then the source coding can be used for data reporting corresponding to the data collection task X (UE sends the collected data to the network). For another example, the data task may be an AI model distribution task (such as the network sends an AI model to the UE), and the AI model distribution task identifier is Y, then the source coding can be used for data distribution corresponding to the AI model distribution task Y (UE receives the AI model sent by the network);

second indication information, used to indicate whether lossy source coding or lossless source coding is used for the first data;

The buffer size used for source encoding;

A source coding algorithm or an algorithm identifier used for the first data.

Step 4: The UE receives the first message, and processes the first data carried by the data plane or the first data of the indicated data task based on the information in the first message, including source encoding the first data to be sent, and/or source decoding the first data to be received. If source coding is used only in the uplink, the UE will perform source coding on the first data to be sent using the corresponding source coding algorithm according to the indication. A method for sending data, the message sent includes a data task identifier and the first data of source coding. Accordingly, the network can determine whether the first data is source encoded and how to perform source decoding based on the data task identifier. If source coding is used only in the downlink, the UE performs source decoding when receiving the first data carried by the data plane. If source coding is used for both the uplink and the downlink, the first data to be sent is source encoded and the first data to be received is source decoded.

Step 5: Optionally, if a check bit is used, when the UE sends the source-coded data, it is also necessary to generate a check bit according to a check algorithm defined in the protocol. The UE sends the check bit and the source-coded data.

Similarly, when the UE receives source-coded data, it needs to interpret the check digit of the source decoded data according to the check algorithm defined in the protocol, and compare it with the received check digit to determine whether the source decoding is correct. If it is wrong and the sender needs to know, 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, feedback information may not be sent, for example, the default is that the decoding is correct when there is no feedback.

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.

Embodiment 3:

In this embodiment, the control plane protocol layer supports source coding.

This embodiment describes a method for the control plane protocol stack to support source coding. If the 5G protocol is taken as an example, the RRC layer supports source coding. This embodiment is mainly aimed at the situation where the existing signaling bearer (such as SRB) is used to transmit large data packets. For example, the current protocol supports QoE reporting through SRB4, MDT data reporting through SRB1 or SRB3, and positioning data reporting through SRB2. Considering the needs of future 6G, it may also include reporting perception data and AI model training data through SRB. Or the network sends the AI model to the UE through SRB, etc. Considering the potential options of the future 6G protocol, the control plane protocol stack may also be the AI function of the wireless access network, or the perception function, etc.

If the source coding capability information is sent to the network side through the UE capability information, then another potential way is to indicate the source coding capability information through the general parameters (General parameters) in the UE capability parameters, as shown in Table 1.

Table 1

In some other embodiments of the present application, another way is to define the UE and the network side to support source coding through the protocol standard, that is, source coding is a mandatory feature. In this case, the UE does not need to report the source coding capability information.

The following is a brief description of the process of source coding interaction between the UE and the network side:

Step 1: The network side device sends a first message to the UE, and the first message includes: first indication information, and the first indication information is used to indicate whether the first data uses source coding; wherein the first data is internal data of the mobile network.

An example of a first message is control signaling of a control plane, and the control signaling is transmitted via a signaling radio bearer (SRB).

In the embodiment of the present application, optionally, the first indication information is used to indicate at least one of the following:

whether to use source coding for the first uplink data;

Whether to use source coding for the first downlink data.

In the embodiment of the present application, optionally, the first message further includes at least one of the following:

second indication information, used to indicate whether lossy source coding or lossless source coding is used for the first data;

The buffer size used for source encoding;

A source coding algorithm or an algorithm identifier used for the first data.

For example, in the current mobile communication protocol, the SRB add, modify and release messages are enhanced to indicate whether source coding is used. The aforementioned similar QoE reporting is more suitable for this method through the configured SRB4, so the established SRB4 is mainly used to carry QoE data.

An example of sending the first message based on RRC signaling is as follows:

For another example, in the current mobile communication protocol, messages for transmitting large data packets can be enhanced so that the source coding configuration is only used for the data configured in the message, rather than all the data carried by the signaling. For the aforementioned MDT or positioning data collection, SRB1, SRB2 and SRB3 are mainly used to carry air interface signaling, and in some cases are used for MDT or positioning data collection. This type of situation is more suitable for enhancing specific configuration messages. For logged MDT, the source coding-based method can store more data within the buffer size specified by the existing protocol. At the same time, the network-side device can determine whether to configure source coding based on the amount of data reported corresponding to each data collection. Usually, when the amount of data reported is large, configuring source coding can reduce the absolute value of the amount of data reported.

If MDT is used as an example, a message enhancement based on RRC signaling is shown in Table 2, which enhances the IE of RRCConnectionReconfiguration (MeasConfig+ReportConfig) and/or LoggedMeasurementConfiguration to indicate whether to use source coding. Optionally, the optional information may also be enhanced.

Table 2

Step 2: The UE receives the first message, and if a signaling bearer is added, a message response message is sent to the network side device.

Step 3: The UE processes the data mapped to the signaling bearer transmission based on the information in the first message. Or the UE performs corresponding processing on the data configured in the first message (e.g., MDT data), including source encoding the transmitted data, and/or source decoding the received data. If source encoding is used only in the uplink, the UE will perform source encoding on the data to be transmitted using the corresponding source encoding algorithm according to the instructions. For example, in a method of sending data reported by the MDT data, the message sent includes traceID and source-coded data. Accordingly, the network can determine whether the data is source-coded and how to perform source decoding based on the traceID. If source coding is used only in the downlink, the UE performs source decoding when receiving the data carried by the data plane. If source coding is used for both the uplink and downlink, source encoding is performed on the transmitted data and source decoding is performed on the received data.

Step 4: Optionally, if a check bit is used, when the UE sends source-coded data, it is also necessary to generate a check bit according to a check algorithm defined in the protocol. The UE sends the check bit and the source-coded data.

Similarly, when the UE receives source-coded data, it needs to interpret the check digit of the source decoded data according to the check algorithm defined in the protocol, and compare it with the received check digit to determine whether the source decoding is correct. If it is wrong and the sender needs to know, 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, feedback information may not be sent, for example, the default is that the decoding is correct when there is no feedback.

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.

Embodiment 4:

In this embodiment, the core network device and the UE support source coding.

This embodiment describes a method for core network equipment to support source coding. The core network equipment includes LMF, SF, a first data plane function, NWDAF, etc. The following takes the first data plane function as an example for data, and an example is shown in FIG3 as a schematic diagram of a data plane protocol stack of a data plane protocol architecture of a UE, a wireless access network, and a core network.

The following is a brief description of the process of source coding interaction between the UE and the network side:

Step 1: The network side device sends a first message to the UE, and the first message includes: first indication information, and the first indication information is used to indicate whether the first data uses source coding; wherein the first data is internal data of the mobile network.

For the core network device, the corresponding first message can be determined based on the characteristics of the required data (e.g., data size, quality of service requirements, etc.). An example of the first message is to include the first message content by enhancing the "LPPrequestlocationinformation" in the LPP protocol. Another example of the first message is to include the first message content by using a first data plane function protocol message (e.g., a data collection request).

In the embodiment of the present application, optionally, the first message further includes at least one of the following:

second indication information, used to indicate whether lossy source coding or lossless source coding is used for the first data;

The buffer size used for source encoding;

A source coding algorithm or an algorithm identifier used for the first data.

Step 2: The UE receives the first message, and if it accepts the data collection request, it sends a response message to the network side device. Or if it is the LPP protocol, it measures the downlink positioning signal and sends "LPPprovidelocationinformation". Among them, the UE processes the data corresponding to the first message configuration based on the information in the first message, including source coding the sent data. The above example only uses source coding in the uplink, so the UE uses the corresponding source coding algorithm to source code the data to be sent according to the instruction.

Step 3: Optionally, if a check bit is used, when the UE sends the source-coded data, it is also necessary to generate a check bit according to a check algorithm defined in the protocol. The UE sends the check bit and the source-coded data.

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.
