It will be appreciated that the data so used may be interchanged under appropriate circumstances such that embodiments of the application are capable of operation in sequences other than those illustrated or described herein, and that the terms "first," "second," etc. are generally used in a generic sense and do not limit the number of terms, e.g., a first term can be one or more than one. In addition, "and/or" in the specification and claims means at least one of connected objects, a character "/", and generally means that the former and latter related objects are in an "or" relationship.

In making the description of the embodiments of the present invention, some concepts used in the following description will be explained first.

Sidelink (Sidelink, also known as direct link) profile:

the Sidelink refers to a wireless link between a User Equipment (UE) and a UE in a New Radio, NR, Long Term Evolution (LTE), and the two UEs can realize direct data transmission between the two UEs through a Sidelink. The wireless link between the sidelinks is also called a PC5 link, and runs through a PC5 protocol. In 3GPP Rel-17, it will be studied to provide a relay service between a UE and a network by using a UE, as shown in fig. 1, wherein the UE providing the relay service is called a relay UE (i.e., relay UE), and the UE provided with the relay service is called a remote UE (i.e., remote UE), a link between the relay UE and the remote UE is a PC5 link, a sidelink interface protocol is operated, a link between the relay UE and a base station is a Uu link, and a Uu link protocol is operated.

The Radio interface Control plane of the sidelink has a PC5 Radio Resource Control (RRC) Protocol, and operates above a Packet Data Convergence Protocol (PDCP) layer and a Radio Link Control (RLC) layer, and the lowest layer is a Medium Access Control (MAC) layer and a physical layer (PHY layer). The radio interface user plane of the sidelink includes, from top to bottom, a Service Data Attachment Protocol (SDAP), PDCP, RLC, MAC, and physical layers.

Layer 2 sidelink relay and layer3 sidelink relay profiles:

currently, the relay structure discussed in 3GPP has two types, Layer 2 (also referred to as Layer 2) and Layer three (Layer3, also referred to as Layer 3). Fig. 2 and 3 show a layer 2 relay based backhaul link control plane protocol stack and a layer3 sidelink relay based backhaul link control plane protocol stack, respectively. For backhaul link based on layer 2 sidelink relay, the remote UE has an RRC connection of PC5 (only Uu RRC protocol stack is shown in the figure) for controlling sidelink connection, and an RRC connection to the base station for controlling connection and service provision with the base station. For backhaul link based on layer3 sidelink relay, the remote UE has a PC5 RRC connection with the relay UE and no Uu RRC connection with the base station. The protocol stack for layer3 relay is omitted. Wherein, SCTP is Stream Control Transmission Protocol (Stream Control Transmission Protocol), NAS is non-access stratum, NG-AP is NG application Protocol.

Uu port wireless link establishment flow:

the RRC signaling flow for the existing radio link setup is shown in fig. 4. A UE sends a Physical Random Access Channel (PRACH) signal to a base station, the base station sends an uplink transmission grant for sending a message three (Msg3) to the UE after receiving the PRACH signal, and the UE sends a radio resource control setup request (RRCSetupRequest) in Msg3 after receiving the uplink transmission grant. And then the base station sends a radio resource control setup (RRCSetup) message to the UE according to the received RRCSetup request, wherein the configuration information carried in the RRCSetup message is used for configuring radio connection configuration parameters between the UE and the base station, including configuration of a radio bearer and a main cell group and the like. After receiving the RRCSetup message, the UE completes radio link configuration according to the configuration parameters therein, and then sends a radio link control complete (RRCSetupComplete) message to the base station.

The information transmission method, the terminal and the network device provided by the embodiments of the present application are described in detail below with reference to the accompanying drawings through specific embodiments and application scenarios thereof.

As shown in fig. 5, an embodiment of the present application provides an information transmission method, including:

step 501, a first terminal sends first information to a network device;

The first terminal is a relay terminal capable of providing a relay service.

It should be noted that the type indication information of the first terminal is specifically used to indicate at least one of the following:

a11, the first terminal is a terminal with layer two side link relay function;

a12, the first terminal is a terminal with layer three side link relay function.

That is, when the first terminal sends the type indication information of the first terminal to the network device, and when the first terminal only has the mode based on the layer two sidelink relay structure, the type indication information indicates that the first terminal is a terminal with a layer two sidelink relay function; when the first terminal only has a mode based on a layer three sidelink relay structure, the type indication information indicates that the first terminal is a terminal with a layer three sidelink relay function; when the first terminal has both the layer two sidelink relay structure-based mode and the layer three sidelink relay structure-based mode, the type indication information indicates that the first terminal is a terminal having both the layer two sidelink relay function and the layer three sidelink relay function.

It should be further noted that the sidelink relay loop setup request indication information includes at least one of the following information:

a21, a first indication for requesting to establish a side link relay loop;

a22, a second indication of an operating mode of the sidelink relay;

it should be noted that the operation mode refers to a mode based on a layer two-sidelink relay structure and/or a mode based on a layer three-sidelink relay structure.

A23, a third indication of the backhaul traffic information of the sidelink trunking;

it should be noted that the backhaul service information generally refers to the type of service, such as video service, voice service, etc.

A24, type indication information of the first terminal.

Further, it should be further noted that the specific implementation manner of step 501 is as follows:

a first terminal sends a first signaling to network equipment, wherein the first signaling carries the first information;

wherein the first signaling comprises: at least one of a radio resource control setup request message (RRCSetupRequest message), a radio resource control setup complete message (RRCSetupComplete message), a radio connection recovery request message (rrcresumererequest message), a radio connection recovery request message one (rrcresumererequest 1 message), a radio connection recovery complete message (RRCResumeComplete message), a terminal assistance message (ueassisteinformation) and a first Radio Resource Control (RRC) message, which is newly introduced in the present application to carry the first information, i.e., a new RRC message, which may be named, for example, a sidelink relay setup request message (sidereturreatrequest message).

It should be noted that, when the Uu link is not established between the first terminal and the network device, the first terminal may request the network device to perform relay loop configuration for the Uu wireless link in the Uu wireless link establishment process, and at this time, the first terminal may send the first information to the network device in a RRCSetupRequest message, a RRCSetupComplete message, a rrcresumererequest message, a RRCResumeRequest1 message, or a RRCResumeComplete message; when the Uu link has been established between the first terminal and the network device, the first terminal may send the first information to the network device in a UEAssistanceInformation or a new RRC message.

For example, when the first terminal carries the indication information of the side-link relay loop establishment request in the RRCSetupRequest message, the RRCResumeRequest message, or the RRCResumeRequest1 message, one of the methods is to redefine the free value field (i.e., spare 'x') of the establishment cause (establnesmincause) of the RRCSetupRequest message, or the free value field (i.e., spare 'x') of the recovery cause (resumesuese) field in the RRCResumeRequest message/RRCResumeRequest 1 message carries the indication information of the side-link relay loop establishment request. For example, a mode of the first terminal based on the layer three sidelink relay structure is indicated by an idle value and/or a mode of the first terminal based on the layer two sidelink relay structure is indicated by an idle value, and further, for example, the mode of the first terminal based on the layer two sidelink relay structure is indicated by an idle value and the return service information is indicated as a specific service type (for example, voice, video and background data transmission service, etc.); another method is to use one of the idle bits as sidelink relay loop setup request indication information for indicating a mode of the first terminal based on a layer three (or layer two) sidelink relay structure.

For example, if the first terminal carries the indication information of the sidelink relay loop establishment request in the RRC message or the RRC message, that is, a new indication parameter is introduced into the two existing RRC messages to indicate that the first terminal is in the mode based on the layer two sidelink relay structure or in the mode based on the layer three sidelink relay structure, optionally, a new indication parameter may also be introduced into the two existing RRC messages to indicate that the backhaul service information is of a specific service type (e.g., voice, video, and background data transmission service, etc.).

It should be further noted that, when the network device receives the first information sent by the first terminal, it may choose to send a rejection message to the first terminal to reject the request for establishing the relay loop. After receiving the rejection request of the relay loop, the first terminal rejects the remote terminal to access the network through the first terminal; the network device may further respond to the first information, and send configuration information established by the relay loop channel to the first terminal, so that the first terminal configures the backhaul channel according to the configuration information after receiving the configuration information established by the relay loop channel sent by the network device.

Specifically, the configuration information includes at least one of the following:

a31, configuration parameters of uplink and downlink backhaul logical channels;

for example, the configuration parameter may be backhaul logical channel configuration of the SRB0 for transmitting the remote terminal, which may be understood as default backhaul logical channel configuration.

A32, access permission parameter of the second terminal;

it should be noted that the second terminal is referred to as a remote terminal.

For example, the access permission parameter may be whether the remote terminal is allowed to access, a service type allowed to access by the remote terminal, and the like.

A33, PC5 logical channel and Uu pass back logical channel configuration mapping relation;

a34, backhaul channel flow control configuration parameters.

It should be further noted that, if the first terminal sends the first information to the network device through the RRCSetupRequest message, the network device may send the configuration information established by the relay loop channel to the first terminal through a radio resource control establishment message (rrcsetupmessage) and/or a radio resource control reconfiguration message (rrcrconfiguration message); if the first terminal sends the first information to the network device through the rrcresemequest message or the rrcresemequest 1 message, the network device may send the configuration information established by the relay loop channel to the first terminal through a radio connection recovery message (rrcresemate message) and/or a rrcreeconfiguration message; if the first terminal sends the first information to the network device through the RRCSetupComplete message, the RRCResumeComplete message, the UEAssistanceInformation message, or the new RRC message, the network device may send the configuration information established by the relay loop channel to the first terminal through the rrcreconconfiguration message.

Optionally, after the step 501, the method according to this embodiment of the present application further includes:

the first terminal sends a side link relay configuration request to the network equipment.

Specifically, the sidelink relay configuration request includes: a configuration request of a system message related to sidelink relaying or a configuration request related to a relay function of the first terminal.

It should be noted that an application scenario of this case is as follows: the trunk loop is already established, but new service transmission exists in the loop, the sidelink trunk configuration needs to be updated at the moment, and a sidelink trunk configuration request needs to be sent to the network equipment to realize configuration updating.

Further, the sidelink relay configuration request may also be used to implicitly indicate at least one of:

a41, the first terminal has the function of side link relay;

a42, the first terminal is willing to be used as a side link relay;

a43, the first terminal requests the network device to configure to the relay terminal or indicates to the network device that there is a relay service requirement.

Further, after receiving the sidelink relay configuration request, the network device may send relay loop configuration information to the first terminal, and the first terminal may perform relay loop configuration after receiving the relay loop configuration information.

It should be noted that the relay loop configuration information includes at least one of the following: and configuring side link time frequency resources and radio bearer related to the relay service.

In summary, in the embodiment of the present application, the first terminal sends the first information to the network device to request the network device to perform the relay loop configuration for the first terminal, so that the network communication process is improved, and the reliability of the relay communication is ensured.
