For example, the data network 160 may include network devices such as servers (including servers that provide multicast services), routers, and gateways.

It should be noted that FIG. 1 is only an exemplary architecture diagram, and should not be understood as a limitation of itself.

For example, in addition to the functional units shown in FIG. 1, the network architecture 100 may also include other functional units or functional entities.

Fig. 2 is an example of the system architecture shown in Fig. 1.

As shown in FIG. 2, the management device 140 may include a management device access and mobility management function (access & mobility management function, AMF), a session management function (session management function, SMF), and a policy control function (policy control function). , PCF) and other functional units.

It should be noted that the network architecture 100 of the embodiment of the present application can support a PDU connection service, and the PDU connection service refers to a service for exchanging PDU data packets between the UE and the DN.

For example, the terminal device 110 and the data network 160 exchange services of PDU data packets. The terminal device realizes the PDU session connection by initiating the establishment of the PDU session. After a single PDU session is established, a data transmission channel between the terminal device 110 and the data network 160 is established. In other words, a PDU session refers to a process of communication between the terminal device 110 and the data network 160.

In addition, the terminal device 110 may establish multiple PDU session connections, and the SMF corresponding to each PDU session may be different or the same. For example, the terminal device 110 may be connected to the same data network through different UPFs. In other words, a PDU session can have multiple N6 interfaces at the same time. The UPF connected to each N6 interface is called a PDU session anchor, and each PDU session anchor provides a different path to the same data network.

In other words, the system architecture 100 needs to support the transmission of services such as factory automation, transport industry, and electrical power distribution.

Based on its transmission requirements for delay and reliability, IIoT introduces the concept of time sensitive network (TSN) network or time stamp counter (TSC), and requires header compression processing for TSN services. TSC services can be carried by Ethernet frames or IP packets.

In other words, in a 5G New Radio (NR) system, the type of PDU session can be not only an IP packet type, but also an Ethernet frame (Ethernet frame) type.

For the PDU layer (PDU layer), when the PDU Session type is Internet Protocol version 4 (Internet Protocol version 4, IPv4), Internet Protocol version 6 (Internet Protocol version 6, IPv6) or IPv4v6, at this time, the PDU session The corresponding data packets are IPv4 packets and/or IPv6 data packets; when the type of PDU Session is Ethernet, the data packets corresponding to the PDU Session are Ethernet frames.

The UPF as the PDU session anchor point can establish a connection with the data network through the NG interface 6 (NG6, N6), so that the terminal device and the network device Ability to interact with user plane data.

In some embodiments of the present application, optionally, the access network protocol layer may depend on the specific access network type.

Exemplarily, the access network type may include a third generation partnership project (The 3rd Generation Partnership Project, 3GPP) access type and a non-3GPP (Non-3GPP, N3GPP) access type. Among them, 3GPP access types may include Long Term Evolution (LTE) access types and New Radio (NR) access types. The non-3GPP access type may include the wireless local area network (Wireless LAN, WLAN) access type.

As an example, a single protocol data unit (Protocol Data Unit, PDU) session (Session) may use multiple access technologies to transmit data. This PDU Session established using multiple access types may be referred to as a Multi-Access PDU (MA PDU) Session. Through Multi-Access PDU Session, terminal equipment can obtain a higher transmission rate, which can save more charges; the network can use N3GPP wireless resources more efficiently, and improve the transmission rate and spectrum utilization.

In other words, a single PDU Session can use multiple access types to transmit data. In other words, a single PDU Session can transmit data on access channels corresponding to multiple access types.

In some embodiments of the present application, optionally, a GTP-U tunnel may be established between the GTP-U receiving entity and the GTP-U sending entity; the GTP-U tunnel is used to forward data packets between GTP-U entities. The GTP-U tunnel can be identified by the Tunnel Endpoint ID (TEID), IP address and UDP port number. TEID is used to clearly identify the tunnel endpoint of a given UDP/IP endpoint in the GTP-U receiving entity.

In some embodiments of the present application, optionally, UDP/IP may be a designated underlying protocol used to transmit GTP messages.

In some embodiments of the present application, optionally, layer 2 is used to provide correct transmission and reception of signaling messages, including partial duplication detection.

For example, layer 1 may include a physical layer (Physical Layer), and the physical layer is a MAC used to provide a transmission channel.

FIG. 4 is a schematic block diagram of a method 200 for compressing an Ethernet frame header provided by an embodiment of the present application. The execution subject of the method 200 may be a compression terminal or a compression device. It should be noted that the method 200 can be used for downlink transmission, can also be used for uplink transmission, or can also be used for sideline transmission. When used for downlink transmission, the compression end may be an access network device/core network device, and the decompression end may be a terminal device. When used for uplink transmission, the compression end can be a terminal device, and the decompression end can be an access network device/core network device. When used for sideline transmission, the compression end can be a terminal device, and the decompression end can also be a terminal device. .

As shown in FIG. 4, the method 200 may include:

S210. The compressor obtains first information, where the first information is used to determine an Ethernet header compression (EHC) mechanism.

S220: The compression end compresses the frame header of the Ethernet frame and/or sends the Ethernet frame based on the EHC mechanism.

For example, the compressor determines the EHC mechanism based on the acquired first information, and compresses the frame header of the Ethernet frame and/or sends the Ethernet frame based on the EHC mechanism. For example, the compression end may determine to compress the frame header of the Ethernet frame based on the EHC mechanism, and send the compressed packet to the decompression end. For another example, the compression end determines not to compress the frame header of the ether frame based on the EHC mechanism, that is, sends the ether frame to the decompression end, which is equivalent to that the compression end sends a complete packet to the decompression end .

In other words, the compression end may determine the packet type of the data packet to be sent at the compression end based on the EHC mechanism. That is, whether the data packet to be sent is a complete packet or a compressed packet. Alternatively, the compression end may determine the state transition mode based on the EHC mechanism.

Determining the EHC mechanism of the Ethernet frame through the first information enables the compressor to use different EHC mechanisms based on different first information, which is equivalent to enabling the compressor to use different EHC mechanisms in different scenarios. Correspondingly, It can improve data transmission efficiency, reduce data transmission delay and improve user experience.

Exemplarily, the compression mechanism of the Ethernet frame may include multiple compression mechanisms, and the compression end and/or the decompression end may select a compression mechanism among the multiple compression mechanisms through the first information, and based on the one This compression mechanism performs state transitions or determines which type of package (compressed package or complete package) to send.

In some embodiments of the present application, the method 200 may further include:

Obtain the configuration information of the EHC.

Exemplarily, the configuration information may include information used to configure functional parameters of the EHC mechanism.

For example, the compression terminal may obtain the functional parameters of each compression mechanism among the multiple compression mechanisms through the configuration information. The configuration information may be information of the semi-static configuration of the network, or information of the dynamic configuration of the network, or pre-defined information, or information predetermined by the compression end and the decompression end. Exemplarily, the compression end may determine the compression mode of the Ethernet frame header according to the obtained configuration information, that is, in which method the state transition is performed, or how to perform header compression, for example, compressing the data in the Ethernet frame header Which domains, the context identifier used when compressing, etc. Of course, the configuration information can also be used to configure the compression parameters of the data part of the Ethernet frame, for example, whether to compress the data part, and the compression method of the data part, etc. In other words, the compression end may also compress the data part of the data packet according to the compression parameters of the data part, and send the compressed Ethernet frame to the decompression end.

It should be understood that the configuration information may be information configured by the first device to the compression end and/or decompression end, so that the compression end can compress the frame header of the Ethernet frame based on the configuration information, and the decompression end The compression end decompresses the compressed Ethernet frame sent by the compression end according to the configuration information. Optionally, the first device may be an access network device, a core network device, or an application layer device, such as a data network node (Data Network Node, DNN), etc.

In the following, description is made by taking the first device sending the configuration information to the compression end as an example.

For example, the first device may be an access network device, and the compression end may be a terminal device. In this case, the first device may configure the header compression parameters for the compressor through a radio resource control (Radio Resource Control, RRC) message, or the first device may also use other messages, such as media access control Downlink messages such as Media Access Control (MAC) Control Element (CE) or Downlink Control Information (DCI) send the configuration information to the compression end.

For another example, the first device may be a core network device, and the compression end may be a terminal device. In this case, the core network device can pass the message between the terminal device and the core network. For example, the core network device may send the configuration information to the terminal device through a Non-Access Stratum (NAS) message. For another example, the core network device may notify the access network device of the configuration information through a non-access stratum (Non-Access Stratum, NAS) message, and then the access network device may pass the Access Stratum (Access Stratum, NAS) message. , AS) layer message forwards the configuration information to the terminal device.

For another example, the first device may be a core network device, and the compression end may be an access network device. In this case, the core network device may send the configuration information to the access network device through a message between the access network device and the core network, such as an N2 message.

It should be noted that the implementation manner of the first device sending the configuration information to the decompression end is similar to the implementation manner of the first device sending the configuration information to the compression end. In order to avoid repetition, details are not repeated here. .

The format of the Ethernet frame that can be used in the embodiment of the present application will be exemplarily described below in conjunction with the accompanying drawings.

Figures 5 to 7 are examples of the frame format of the Ethernet frame provided in the embodiments of the present application.

As shown in FIG. 5, the Ethernet frame may be an Ethernet 802.3 raw frame type, and the Ethernet frame may include a header and a data part of the Ethernet frame. The header may also be referred to as an Ethernet frame header. The header may include multiple fields (or fields, subheaders), for example, a destination address field, a source address field, and a type/length field. The data part may include data and/or stuffing bits. In addition, the Ethernet frame may also include two parts that are not transmitted in the 5G network, a preamble and a frame check sequence (FCS).

As shown in FIG. 6, the Ethernet frame may be an Ethernet II frame type, and the Ethernet frame may include a header and a data part. The header may include multiple fields, for example, a destination address field, a source address field, and a type field. The data part may include data. In addition, it can also include two parts that are not transmitted in the 5G network, namely the preamble and the FCS.

It should be noted that when the PDU session is of the Ethernet frame type, the Ethernet PDU may carry a virtual local area network (Virtual Local Area Network, VLAN) domain or may not carry a VLAN header, and the corresponding Ethernet frame structure is different. The VLAN domain may also be called Q-tags (Q-tags), which may include a user tag (C-tag) and a service tag (S-tag), and the user tag may also be called a customer VLAN domain (Customer VLAN domain). ), the service tag may also be referred to as a service VLAN domain (Service VLAN domain).

As shown in FIG. 7, a frame format of a VLAN field may be added to the frame format shown in FIG. 5 or FIG. 7, and the VLAN field may be used to indicate the information of the VLAN to which the Ethernet frame belongs.

It should be understood that the frame formats shown in FIG. 5 to FIG. 7 are merely examples, and should not be particularly limited to the embodiment of the present application.

In some embodiments of the present application, the EHC mechanism includes at least one of the following items:

The mechanism of state transition based on feedback information;

A mechanism for state transition not based on the feedback information;

A mechanism for sending a complete packet or a compressed packet based on feedback information, the complete packet includes the first header information of the Ethernet frame, and the compressed packet does not include the first header information;

A mechanism for sending the complete package or the compressed package not based on the feedback information;

A mechanism for state transition based on multiple transmissions of the same type of packet; and

A mechanism for sending the complete package or the compressed package based on multiple transmissions of the same type of package.

Exemplarily, the mechanism for performing state transition based on multiple transmissions of the same type of packets may be a mechanism for performing state transition based on multiple consecutive transmissions of the same type of packets. The mechanism for sending the complete package or the compressed package based on multiple transmissions of the same type of package may be a mechanism for sending the complete package or the compressed package based on multiple consecutive transmissions of the same type of package .

Exemplarily, the sending situation may include that packets of the same type have been sent multiple times and/or packets of the same type have not been sent multiple times. For example, the sending situation may include that packets of the same type have been sent consecutively multiple times and/or packets of the same type have not been consecutively sent multiple times.

For example, the EHC mechanism of the Ethernet frame may be the first mechanism. The first mechanism may also be referred to as a feedback mechanism.

Wherein, the first mechanism may refer to:

After receiving the feedback information sent by the decompression end, the compression end sends a complete package or compressed package to the decompression end, the feedback information is used to indicate whether the decompression end has successfully established the context information corresponding to the context identifier, so The complete packet includes the first frame header information of the Ethernet frame, and the compressed packet does not include the first frame header information.

For example, if the feedback information is used to indicate that the decompression end has successfully established the context information corresponding to the context identifier, the compression end sends the compressed end to the decompression end after receiving the feedback information sent by the decompression end. Bag. For another example, if the feedback information is used to indicate that the decompression end does not have valid context information/the context information corresponding to the context identifier is not successfully established, the compression end will forward the feedback information sent by the decompression end The decompression end sends the complete package.

In other words, the state can be based on the feedback mechanism.

It should be understood that the complete package may be used for the decompression end to establish context information corresponding to the context identifier, and the context information may be used to restore or decompress the compressed package.

The working principle of the first mechanism will be exemplified below.

One data stream may include multiple data packets, and the process of the compression end sending the data stream to the decompression end is the process of the compression end sending the multiple data packets to the decompression end. Based on this, the compression end may determine whether the data packet to be sent is a complete packet or a compressed packet based on the EHC mechanism.

In the process of the compression end sending the multiple data packets to the decompression end, the compression end first establishes at least one context information (context), and associates the at least one context information with at least one context identifier Character (Context identification, CID). For example, the compression terminal may establish at least one sub-object channel, and each sub-object channel of the at least one sub-object channel has (or stores) corresponding context information. The context information can be used to recover compressed data packets.

Then, the compression end may send the complete packet to the decompression end.

Exemplarily, the complete packet may include the first frame header information of the Ethernet frame. For example, the first frame header information may be at least part of the entire frame header information. The complete packet may include a context identifier and complete header information (full header, FH). The complete header information may also be referred to as original sub-header information. The original sub-header information may be uncompressed sub-header information. The complete package may also include package type indication information, and the package type indication information may be used to indicate that the data packet is a complete package or a compressed package, that is, the decompression end may determine the received package based on the package type indication information Whether the data package is a complete package or a compressed package. The packet type indication information may occupy 1 bit.

After the decompression end receives the complete package, the decompression end may establish context information corresponding to the at least one context ID (Context ID, CID) according to the information in the complete package.

After the decompression end receives the complete package sent by the compression end, the decompression end may establish context information corresponding to the context identifier based on the complete package, and may send feedback information to the compression device. The feedback information may be used to feed back the establishment result of the context information corresponding to the context identifier, and the establishment result may be used to indicate whether the decompression end has successfully established the context information corresponding to the context identifier. The feedback information can be used to modify the EHC mechanism of the compression end or the decompression end.

Exemplarily, the feedback information is an Acknowledgement (ACK) to indicate that the context information corresponding to the context identifier is successfully established. For another example, the feedback information includes a negative acknowledgement (Negative Acknowledgement, NACK) to indicate that the context information corresponding to the context identifier has not been successfully established.

Exemplarily, as long as the feedback information is received, it can be considered that the context information corresponding to the context identifier is successfully established.

After the compression end receives the feedback information sent by the decompression end, it may determine whether to send the compressed package or the complete package based on the feedback information.

For example, if the feedback information is used to indicate that the decompression end has not successfully established the context information corresponding to the context identifier, the compression end sends the complete information to the decompression end after receiving the feedback information sent by the decompression end. Package so that the decompression end continues to establish the context information corresponding to the context identifier. It should be noted that the package sent by the compression end may be a complete package or a compressed package before or before receiving the feedback information.

For another example, if the feedback information is used to indicate that the decompression end has successfully established the context information corresponding to the context identifier, the compression end sends the feedback information to the decompression end after receiving the feedback information sent by the decompression end Archive. After the decompression end receives the compressed package, it can correspond the compressed package to the sub-object channel corresponding to the context identifier, that is, it can restore the header information of the compressed package based on the context identifier in the package and its corresponding context information. In other words, the decompression end may obtain the context information corresponding to the context identifier according to the context identifier in the compressed package, refill the information in the data package, and restore the compressed package.

For example, taking a compressed package including a Q-tag as an example, the compressed package includes context ID1; after the decompression end receives the compressed package sent by the compression end, the compressed package may be mapped to the sub-context ID1 corresponding to context ID1. In the object channel, so that the decompression end can restore the compressed package according to the information included in the compressed package and the context information in the sub-object channel corresponding to the context ID1.

Exemplarily, the compressed packet may include a context identifier and compressed header information (compressed header, CH). For example. The compressed package does not include the first frame header information included in the complete package. The compressed package may also include second frame header information. The second frame header information is sub-header information not included in the complete packet. The sub-header information not included in the complete package may be sub-header information that is not included or stored in the context information corresponding to the context identifier. The compressed package may also include a package type indication, the package type indication information may be used to indicate that the data package is a complete package or a compressed package, and the decompression end may determine the received data package based on the package type indication information Is it a complete package or a compressed package. For example, the packet type indication information may occupy 1 bit.

The following describes the contents of the complete package and the compressed package in combination with the frame header of the Ethernet frame.

Exemplarily, the frame header of the Ethernet frame may include a variable part and a static part. For example, the variable part may include a VLAN domain, a length and type domain, etc., and the static part may include a source address, a destination address, and the like. Based on this, the complete packet may include part or all of the sub-header information in the static part of the Ethernet frame, and the compressed packet may include part or all of the sub-header information in the variable part of the Ethernet frame.

Exemplarily, the complete package or the compressed package may include sub-header information of a partial category of the Ethernet frame, and the sub-header of the partial category may also be referred to as the sub-header information in the domain of the partial category. For example, the complete package or the compressed package may include uncompressed information of sub-headers of partial categories. Exemplarily, the category of the sub-header of the Ethernet frame may include at least one of the following: static category, known static (static-known) category, defined static (static-def) category, speculation (inferred) category and variable (changing) category.

For example, the complete package may include sub-header information of immutable categories. For example, the unchanged category may include a static category, a static-known category, a static-def category, and an inferred category. For another example, the unchanged type may include some subheaders in the static category, the static-known category, the static-def category, and the inferred category. For example, the compressed package may include sub-header information of the changing category. For another example, the compressed package may be the sub-header information of the changing category and another part of the sub-header information in the inferred category.

Exemplarily, the complete packet may include all sub-header information in the frame header of the Ethernet frame. The compressed packet may include at least part of the sub-header information in the frame header of the Ethernet frame, and the at least part of the sub-header information may also be referred to as the sub-header information in the partial field. For example, the compressed package may include at least one of the following: destination address, source address, Ethernet type, Ethernet length, Tag Protocol ID (TP-ID), Precedence Code Point, PCP), drop indication (Drop Eligible Indicator, DEI), VLAN ID, LLC information, and padding bits.

Wherein, the TP-ID can be used to indicate the frame type. The PCP or priority (Priority, PRI) can be used to indicate the priority of the frame. When the network is congested, a data packet with a higher PCP priority is sent first. The DEI may be used to indicate the discarding priority. When the network is congested, the data packets with the lower priority are discarded first.

It should be noted that the sub-headers included in the above Ethernet frame header are only examples. With the update and development of the standard, the sub-headers in the Ethernet frame header can be deleted, added, or updated. In addition, the information used to configure the parameters of the compression mechanism can be used to determine which sub-header information or types of sub-headers are compressed.

FIG. 8 is a schematic block diagram of the principle of the first mechanism provided by an embodiment of the present application.

As shown in FIG. 8, the at least one piece of context information established by the compressor includes Context 1, Context 2, and Context 3 corresponding to CID1, CID2, and CID3, respectively. The data packet to be transmitted sent by the compression end to the decompression end is an Ethernet frame, and the Ethernet frame may include a frame header and a bearer. After the compression end sends the complete package to the decompression end, the decompression end sends feedback information to the compression end, and the compression end sends the compressed packet to the decompression end. The complete package may include a context identifier CIDx, complete header information and a payload, the feedback information may include a context identifier CIDx, and the compressed package may include a context identifier CIDx, compressed header information, and a payload.

Of course, in the embodiment of the present application, the EHC mechanism of the Ethernet frame may be other mechanisms.

Exemplarily, the EHC mechanism of the Ethernet frame may be the second mechanism.

Wherein, the second mechanism refers to:

The compression end continuously sends multiple complete packets to the decompression end and then sends compressed packets to the decompression end, and/or, the compression end sends multiple compressed packets to the decompression end continuously, and then forwards all the compressed packets to the decompression end. The decompression end sends the complete package.

For example, the number of the multiple complete packages or the number of the multiple compressed packages may be a pre-configured or predefined number, may also be the result of negotiation between the compression end and the decompression end, or information indicated by other devices.

When the Ethernet frame is transmitted through the second mechanism, there is no available reverse link between the compression end and the decompression end, or the reverse link is unavailable, or the reverse link channel quality is poor, Or when the channel quality is good, the success rate of data transmission can be improved and the user experience can be improved.

Hereinafter, taking the EHC mechanism including the first mechanism or the second mechanism as an example, the method for determining the EHC mechanism by the compressor will be described.

In some embodiments of the present application, the method 200 may further include:

Based on the first information, the compression end determines the first mechanism or the second mechanism as the EHC mechanism.

For example, the compression end may be directly based on the first information, and the compression end determines the first mechanism or the second mechanism as the EHC mechanism. For another example, the compression end may first determine the network environment or interference environment between the compression end and the decompression end based on the first information, and then determine the EHC based on the network environment or interference environment mechanism.

The following describes an implementation manner in which the compression end determines the EHC mechanism directly based on the first information.

In some embodiments of the present application, the first information includes first indication information, and the first indication information is used to indicate the first mechanism or the second mechanism; based on this, the compression end may The first mechanism or the second mechanism indicated by the first indication information is determined to be the EHC mechanism.

In other words, the first indication information can be directly used to indicate the frame header compression mechanism of the Ethernet frame.

In some embodiments of the present application, the first information includes second indication information, and the second indication information is used to indicate the environmental level of the network environment between the compression end and the decompression end. Based on this, the compression end may determine the EHC mechanism based on the environment indicated by the second indication information. For example, if the environmental level indicated by the second indication information is less than a first threshold, the compression end determines the first mechanism as the EHC mechanism; and/or if the environmental level indicated by the second indication information is greater than Or equal to the first threshold, the compression end determines the second mechanism as the EHC mechanism. For another example, if the environmental level indicated by the second indication information is greater than or equal to the first threshold, the compression end determines the first mechanism as the EHC mechanism; and/or if the second indication information indicates The environmental level is less than the first threshold, and the compression end determines the second mechanism as the EHC mechanism. Optionally, the first threshold is a predefined threshold, or the first threshold is a preconfigured threshold, or the first threshold is a dynamically configured threshold. Optionally, the first information includes the first threshold.

As an example, in the case that the magnitude of the environmental level indicated by the second indication information is proportional to the magnitude of the interference degree of the network environment between the compression end and the decompression end, if the second indication information indicates If the environmental level of is less than the first threshold, the compression end determines the first mechanism as the EHC mechanism; and/or if the environmental level indicated by the second indication information is greater than or equal to the first threshold, the The compression end determines the second mechanism as the EHC mechanism.

As another example, in the case that the magnitude of the environmental level indicated by the second indication information is inversely proportional to the magnitude of the interference degree of the network environment between the compression end and the decompression end, if the second indication information If the indicated environmental level is greater than or equal to the first threshold, the compression end determines the first mechanism as the EHC mechanism; and/or if the environmental level indicated by the second indication information is less than the first threshold, The compression end determines the second mechanism as the EHC mechanism.

In some embodiments of the present application, the first information includes an indication of whether the link from the decompression end to the compression end is controlled, or an indication of whether the reverse link is controlled. Exemplarily, when controlled, the first mechanism may be the EHC mechanism; otherwise, the second mechanism may be the EHC mechanism.

In some embodiments of the present application, the first information includes the channel occupation time (Channel Occupancy Time, COT) or controlled time of the decompression end; or the first information also includes instructions for indicating the COT Or the information of the controlled time, the controlled time is the time when the target link can be used or the time when the feedback information can be received/transmitted, and the target link includes the time from the compression end to the decompression end The reverse link or the link from the decompression end to the compression end; based on this, if the transmission time of the target link or the transmission time of the feedback information is within the COT or the controlled time, so The compressor determines the first mechanism as the EHC mechanism; and/or if the transmission time of the target link or the transmission time of the feedback information is outside the COT or the controlled time, The compression end determines the second mechanism as the EHC mechanism.

In other words, when the feedback information has transmission resources, the compression end determines the first mechanism as the EHC mechanism, and when the transmission channel of the feedback information is unavailable or does not have transmission resources, The compression end determines the second mechanism as the EHC mechanism.

In some embodiments of the present application, the first information includes channel quality information, and the channel quality information is used to indicate the channel quality of the reverse link from the decompression end to the compression end; based on this, if If the channel quality is greater than or equal to a second threshold, the compression end determines the first mechanism as the EHC mechanism; and/or if the channel quality is less than the second threshold, the compression end will The second mechanism is determined to be the EHC mechanism. Optionally, the second threshold is a predefined threshold, or the second threshold is a preconfigured threshold, or the second threshold is a dynamically configured threshold. Optionally, the first information includes the second threshold.

Exemplarily, the channel quality information includes at least one of the following information: received signal strength indication (RSSI), reference signal receiving power (RSRP), reference signal receiving quality ( Reference Signal Receiving Quality, RSRQ) and the number of listen before talk (Listen Before Talk, LBT).

In other words, in the case that the channel quality can satisfy the transmission of the feedback information, the compression end determines the first mechanism as the EHC mechanism, and in the case that the channel quality cannot satisfy the transmission of the feedback information, the The compression end determines the second mechanism as the EHC mechanism.

In some embodiments of the present application, the first information includes the frequency band used by the reverse link from the decompression end to the compression end; based on this, if the frequency band is a licensed frequency band, the compression end will The first mechanism is determined to be the EHC mechanism; and/or if the frequency band is an unlicensed frequency band, the compression end determines the second mechanism as the EHC mechanism.

In other words, if the working frequency band between the compression end and the decompression end is a licensed frequency band, the compression end determines the first mechanism as the EHC mechanism, if the compression end and the decompression end The working frequency band in between is an unlicensed frequency band, and the compression end determines the second mechanism as the EHC mechanism.

In some embodiments of the present application, the compression terminal or the decompression terminal may be a communication device in an NR-U system. For example, the working frequency band of the compression end or the decompression end may be an unlicensed frequency band. For example, the working frequency band (Band) of NR-U can be 5 gigahertz (GHz) unlicensed spectrum and 6 GHz unlicensed band.

In other words, the working scenario of the compression end or the decompression end includes any one of the following:

Scenario A: Carrier aggregation scenario, that is, primary and secondary cells (Primary Secondary Cell, PSCell) work on licensed spectrum, and secondary cells (Secondary Cell, SCell) aggregate and work on unlicensed spectrum through carrier aggregation.

Scenario B: A dual-connection working scenario, that is, the PCell works on the long-term evolution (Long Term Evolution, LTE) licensed spectrum, and the PSCell works on the NR unlicensed spectrum.

Scenario C: Independent work scenario, that is, NR works as an independent cell on an unlicensed spectrum.

Scenario D: NR single-cell scenario, that is, the uplink (UL) works on the licensed spectrum, and the downlink (DL) works on the unlicensed spectrum.

Scenario E: A dual-connection working scenario, that is, the PCell works on the NR licensed spectrum, and the PSCell is on the NR unlicensed spectrum.

It should be noted that on the unlicensed spectrum, NR-U needs to ensure fairness with other systems that are already working on these unlicensed spectrums, such as wireless fidelity (Wireless-Fidelity, WiFi). Among them, the principle used to ensure fairness may be that the impact of NR-U on systems that have been deployed on unlicensed spectrum (such as WiFi) cannot exceed the impact between these systems.

In order to ensure fair coexistence between systems on the unlicensed spectrum, the energy detection mechanism can be used as a coexistence mechanism. For example, in the Listen Before Talk (LBT) mechanism, the basic principle of the LBT mechanism is that a base station or terminal (transmitting end) needs to listen for a period of time according to regulations before transmitting data on an unlicensed spectrum. If the listening result indicates that the channel is idle, the transmitting end can transmit data to the receiving end. If the listening result indicates that the channel is in an occupied state, the transmitting end needs to back off for a period of time according to regulations before continuing to listen to the channel until the channel listening result is idle before transmitting data to the receiving end.

Exemplarily, the channel access mechanism (category) may include at least one of the following:

Mechanism 1: Direct transmission mechanism, that is, the transmitting side (TX) can quickly transmit after the switching gap (switching gap) in the channel occupation time (Channel Occupancy Time, COT). Wherein, the conversion gap refers to the conversion time when the transmission is received, for example, it can be defined that the conversion gap does not exceed 16 us.

Mechanism 2: LBT mechanism that does not require random back-off, that is, the length of time the transmitting side (TX) listens to the channel is a certain length of time, for example, 25 us.

Mechanism 3: The random back-off LBT mechanism is based on a fixed contention window LBT. Specifically, in the LBT process, the transmission side randomly selects a random value in the contention window to determine the time to listen to the channel.

Mechanism 4: Random back-off LBT mechanism. LBT is not fixed based on an unfixed contention window. Specifically, in the LBT process, the transmission side randomly selects a random value in the contention window to determine the time to listen to the channel. The competition window is variable. For the terminal, the base station needs to transmit data to the terminal within the Maximum Channel Occupancy Time (MCOT) time. If the base station does not preempt the channel, that is, outside of the MCOT, the terminal will not receive the transmission from the base station. The scheduling data for this terminal.

For the uplink transmission initiated by the terminal device, it may include at least one of the following:

Scheduling Request (SR), used to request uplink resources;

Physical random access channel (Physical Random Access Channel, PRACH), random access channel (Random Access Channel, RACH) triggers the user equipment (User Equipment, UE) to need to send message 1 (msg1);

Physical Uplink Shared Channel (PUSCH), which includes uplink data transmission based on configured grant and uplink data transmission based on dynamic grant;

Physical layer signaling, which can include ACK/NACK (ACK/NACK) feedback and channel state information (Channel State Information, CSI) and other report information;

It should be noted that on the unlicensed frequency band, the terminal device needs to use LBT to monitor whether the channel is available before transmitting SR, PRACH or PUSCH. If it is not available, that is, LBT fails, the terminal device needs to wait until the next transmission opportunity Execute LBT again. If LBT failure is detected, the MAC layer needs to be notified of the LBT failure information.

In some embodiments of the present application, the first information includes the frequency band used by the reverse link from the decompression end to the compression end; the first information also includes the COT or controlled control of the decompression end Time, or the first information further includes information for indicating the COT or the controlled time, and the controlled time is the time when the target link can be used or the time when the feedback information can be received/transmitted , The target link includes the reverse link from the compression end to the decompression end or the link from the decompression end to the compression end; based on this, if the frequency band is an unlicensed frequency band, and the target link The transmission time of the channel or the transmission time of the feedback information is within the COT or the controlled time, and the compression end determines the first mechanism as the EHC mechanism; and/or if the frequency band is Unlicensed frequency band, and the transmission time of the target link or the transmission time of the feedback information is outside the COT or the controlled time, the compression end determines the second mechanism as the EHC Mechanism; and/or if the frequency band is a licensed frequency band, and the transmission time of the target link or the transmission time of the feedback information is within the COT or the COT, the compression end will use the first mechanism Determined as the EHC mechanism; and/or if the frequency band is a licensed frequency band, and the transmission time of the target link or the transmission time of the feedback information is outside the COT or the controlled time, so The compression end determines the second mechanism as the EHC mechanism.

In other words, the EHC mechanism may be determined based on whether the feedback information has transmission resources and whether the working frequency band between the compression end and the decompression end is a licensed frequency band.

In some embodiments of the present application, the first information includes the frequency point used by the reverse link from the decompression end to the compression end; based on this, if the frequency point is an authorized frequency point, the The compressor determines the first mechanism as the EHC mechanism; and/or if the frequency is an unlicensed frequency, the compressor determines the second mechanism as the EHC mechanism.

In other words, if the working frequency point between the compression end and the decompression end is an authorized frequency point, the compression end determines the first mechanism as the EHC mechanism, if the compression end and the decompression end The working frequency point between the compression ends is an unlicensed frequency point, and the compression end determines the second mechanism as the EHC mechanism.

In some embodiments of the present application, the first information includes the frequency point used by the reverse link from the decompression end to the compression end; the first information also includes the COT or the receiving end of the decompression end. Control time, or the first information further includes information for indicating the COT or the controlled time, and the controlled time is the time that the target link can be used or the feedback information can be received/transmitted Time, the target link includes the reverse link from the compression end to the decompression end or the link from the decompression end to the compression end; based on this, if the frequency point is an unlicensed frequency point, and all The transmission time of the target link or the transmission time of the feedback information is within the COT or the controlled time, and the compression end determines the first mechanism as the EHC mechanism; and/or if The frequency point is an unlicensed frequency point, and the transmission time of the target link or the transmission time of the feedback information is outside of the COT or the controlled time, and the compression end uses the second mechanism Determined as the EHC mechanism; and/or if the frequency point is an authorized frequency point, and the transmission time of the target link or the transmission time of the feedback information is within the COT or the The terminal determines the first mechanism as the EHC mechanism; and/or if the frequency point is an authorized frequency point, and the transmission time of the target link or the transmission time of the feedback information is located in the COT or Outside the controlled time, the compression end determines the second mechanism as the EHC mechanism.

In other words, the EHC mechanism may be determined based on whether the feedback information has transmission resources and whether the working frequency point between the compression end and the decompression end is an authorized frequency point.

In some embodiments of the present application, the first information includes information used to determine or indicate a target environment, and the target environment is used to indicate a transmission or interference environment between the compression end and the decompression end; Based on this, based on the first mapping relationship, the compression end determines the mechanism corresponding to the target environment as the EHC mechanism, and the first mapping relationship includes a correspondence relationship between at least one environment and at least one mechanism, and the at least one The environment includes the target environment. Optionally, the first mapping relationship is predefined information, or the first mapping relationship is pre-configured information, or the first mapping relationship is dynamically configured information. Optionally, the first information includes the first mapping relationship.

In other words, different transmission or interference environments between the compression end and the decompression end may be associated with different compression mechanisms.

As an example, the at least one environment corresponds to at least one environmental level identifier. For example, the at least one environmental level is at least two environmental levels.

As another example, the at least one environment includes at least one type of environment.

For example, the at least one type of environment includes a controllable environment and/or a non-controllable environment.

Wherein, the controllable environment means that the transmission or interference environment between the compression end and the decompression end satisfies at least one of the following:

There is no different system in the network system to which the compression terminal and the decompression terminal belong;

There is a controlled different system or controlled time in the network system to which the compression terminal and the decompression terminal belong, the controlled different system corresponds to or has a controlled time, and the controlled time is the target link The time used or the time when the feedback information can be received/transmitted, the target link includes the reverse link from the compression end to the decompression end or the link from the decompression end to the compression end; and

Load or interference of the feedback link between the compression end and the decompression end is less than a preset threshold;

The non-controllable environment refers to: the transmission or interference environment between the compression end and the decompression end satisfies at least one of the following:
