At least one of the first recommended bit rate information and the second recommended bit rate information controls a protocol data unit (Protocol Data Unit, PDU) through a packet data convergence protocol (Packet Data Convergence Protocol, PDCP), and the adaptation layer Control PDU, radio link layer control (Radio Link Control, RLC) control PDU or media access control (Media Access Control, MAC) control element (Control Element, CE) signaling is sent.

In the case where the first recommended bit rate information is carried in the adaptation layer control PDU, RLC control PDU or MAC CE signaling, it is necessary to explicitly carry the remote UE identifier and the end-to-end radio bearer (Radio Bearer, RB) identifier , that is, the first recommended bit rate information includes the first recommended bit rate, the identifier of the first remote terminal, and the first radio bearer RB identifier, or includes the second recommended bit rate, the first remote terminal The identity of the terminal, and the identity of the second RB, or include the second recommended bit rate, the identity of the other remote terminal, and the second RB identity, or include the second recommended bit rate, the identity of the first remote terminal an identifier of the other remote terminal, and an identifier of the second RB.

If the first remote terminal is the sender of the first recommended bit rate information, and the receiver is other remote terminals, then the first recommended bit rate information includes identifiers of other remote terminals.

The above situation is also applicable to the second recommended bit rate information, which will not be repeated here.

It should be noted that the end-to-end recommended bit rate between the first remote terminal and the network side device included in the first recommended bit rate information may be the same as the end-to-end recommended bit rate between the first remote terminal and the network side device included in the second recommended bit rate information. The end-to-end recommended bitrate is the same or different between devices.

The end-to-end recommended bit rate between the first remote terminal and other remote terminals included in the first recommended bit rate information may be the same as the end-to-end recommended bit rate between the first remote terminal and other remote terminals included in the second recommended bit rate information. The end-to-end recommended bitrates of the two are the same or different.

In Layer 2 (Layer 2, L2) UE-to-Network (U2N) architecture, the end-to-end recommended bit rate control and request process can be performed, where the two final endpoints of control and request are the next generation base station Between the node (next Generation Node Base, gNB) and remote UE, the granularity of control and request can be remote UE end-to-end RB, and the intermediate relay node can also participate in the request, and the granularity is also a remote UE end-to-end RB.

For the sending method of control and request, the path is between the remote UE and the base station, or between the relay UE and the base station, and the PDCP control PDU (remote UE end-to-end RB granularity), or the adaptation layer control PDU, RLC control PDU can be used Or when MAC CE signaling is sent through the adaptation layer control PDU, RLC control PDU or MAC CE signaling, it needs to explicitly carry the remote UE identifier and the end-to-end RB identifier, and the relay UE can according to the request it receives Information and its own measurement information on the links on both sides (the Uu link with the base station, and the direct cellular communication protocol (PC5) link with the remote UE), and the recommended bit rate with a small value after synthesis, Make a request to gNB.

In the L2 UE-to-UE (UE-to-UE, U2U) architecture, the end-to-end recommended bit rate control and request process can be performed, where the two final endpoints of control and request are between two remote UEs, control and request The granularity is remote UE end-to-end RB, and the relay UE in the middle can also participate in the request, and the granularity is also a remote UE end-to-end RB.

For the sending method of control and request, the path is between remote UE1 and peer remote UE2, or between relay UE and remote UE, and can control PDU through PDCP (remote UE end-to-end RB granularity), or adaptation layer control PDU , RLC control PDU or MAC CE transmission, when sending through the adaptation layer control PDU, RLC control PDU or MAC CE signaling, it is necessary to explicitly carry the remote UE identifier and the end-to-end RB identifier, and the control and request can be fixed by default. direction, or explicitly carry direction indication, or indication information used to indicate control or request, the relay UE can combine the recommended bit rate with a small value based on the request information it receives and its own measurement information on both links , make a request to the remote UE.

In the above U2U architecture, the end-to-end two ends are remote UE1 and remote UE2. If remote UE1 is the controller, the recommended bit rate information sent by remote UE1 includes the end-to-end recommended bit rate, the identity of remote UE2, remote UE1 and remote UE1. An end-to-end (End-to-End, E2E) RB identifier between UE2 and indication information. Optionally, since the remote UE1 is the initiating node, the remote UE1 may be carried in the addressing information, or the identifier of the remote UE1 may be explicitly included in the recommended bit rate information.

The first recommended bit rate information includes a recommended bit rate for a target object associated with the first remote terminal. In the U2N scenario, the network side device is the controller, and the remote UE is the requester. In the U2U scenario, where the two ends of the communication are a remote UE and another remote UE, the first recommended bit rate information or the second recommended bit rate information also needs to include information indicating that the first remote terminal is the requester or the controller. Instructions. The requester can also be called the proposer or receiver, and the controller can also be called the decider or sender.

The second recommended bit rate information may also include the recommended bit rate of the target object associated with the first remote terminal, and the second recommended bit rate information may also include indication information, and the indication information is used to indicate that the first The remote terminal is either the controller or the requester.

In the above, the indication information includes at least one of the following:

A direction identification bit used to indicate the control direction, the first remote terminal is determined by the control party or the requester according to the control direction;

An identification bit used to indicate that the first remote terminal is a controller or a requester;

An indication field for indicating a source terminal identity and a target end identity, where the source terminal identity indicated by the indication field is the identity of the first remote terminal, and the target end identity is an identity of another terminal, or the indication field indicates The target terminal identifier is the identifier of the first remote terminal, and the source terminal identifier is the identifier of the other remote terminal.

Specifically, each direction is divided into a clear identification, such as remote UE1->remote UE2 as direction 1, remote UE2->remote UE1 as direction2, in the direction of direction 1, the default remote UE1 decides, remote UE2 recommends, in direction 2 In the above, by default, remote UE2 decides, and remote UE1 recommends. direction 1 and direction 2 are the direction identification bits, and according to the direction identification bits, it can be known that remote UE1 and remote UE2 are the controller or the requester.

If the signaling direction from remote UE1 to remote UE2 is controlled, the bit (bit) is set to 0, and if the reverse direction is controlled, the bit is set to 1; the bit is the direction identification bit, and the remote UE1 can be known according to the direction identification bit , remote UE2 is the controller or the requester.

The first recommended bit rate information (or the second recommended bit rate information) can carry source (source) UE identification (Identity Document, ID), target (target) UE ID and RB ID information, the advantage of this is direction and/or control (or request) information is implicit in the source terminal identification (ie source UE ID) and target terminal identification (ie target UE ID), for example, in the recommended bit rate information sent by remote UE1 to remote UE2, if the source UE ID is remote UE1 If the target UE ID is the identity of remote UE2, the control direction is remote UE1->remote UE2; if the source UE ID is the identity of remote UE2, and the target UE ID is the identity of remote UE1, the control direction is remote UE2-> remote UE1.

Whether the first remote terminal is the controlling party or the recommending party can adopt a default regulation, or explicitly indicate, for example, use an identification bit to indicate. For example, it is carried by 1 bit, if the bit is 0, it means the controller, and if the bit is 1, it means the suggester.

In the above, the target object includes at least one of the following:

End-to-end RB identification;

PC5 Logical Channel Identify (LCID);

Destination layer 2 identification;

source layer 2 identification;

PC5 link;

PC5 priority;

Channel Busy Ratio (CBR) interval.

Since U2U involves between two remote UEs, for example, between the first remote UE and the second remote UE, the following granularity can be used when exchanging recommended bit rates:

Use PC5 LCID granularity: It means that the recommended bit rate is controlled or requested for a PC5 LCID. For the UE at the service source (the UE at the service source can be understood as a remote UE), the rate of a logical channel will be set according to the bit rate;

Use PC5's unique destination layer 2 identifier (Destination L2 ID) granularity: it means that the recommended bit rate is controlled or requested for a specific Destination L2 ID, and the UE at the source end of the service will be sent according to the bit rate setting Rate to a Destination L2 ID;

Use PC5's unique Source L2 ID and Destination L2 ID granularity; the recommended bit rate is to control or request a specific Source L2 ID and Destination L2 ID. Bit rate setting is the rate sent from a specific Source L2 ID to a specific Destination L2 ID;

Use PC5 link granularity: means that the recommended bit rate is controlled or requested for a specific PC5 link, and the UE at the service source will set the specific PC5 link transmission rate according to the bit rate;

Use PC5 priority granularity: It means that the recommended recommended bit rate is controlled or requested for a specific PC5 priority, and the UE at the service source will set the specific PC5 priority transmission rate according to the bit rate;

Use CBR interval (Range) granularity; it means that the recommended recommended bit rate is controlled or requested for a specific CBR interval, and the UE at the service source will set the transmission rate when it is located in a specific CBR interval according to the bit rate.

The recommended bit rate determination method in this application can realize end-to-end recommended bit rate interaction. Due to the end-to-end control, in addition to the load and link quality of the Uu link, the load and link quality of the PC5 link also need to be considered. It is equivalent to controlling or requesting the final end-to-end recommended bit rate according to the capacity and achievable rate of the end-to-end bearer on the entire transmission path.

That is to say, whether the gNB is controlling or the remote UE is making a request, it is necessary to know the load and link quality of all paths between the gNB and the remote UE. The gNB can request or configure the relay UE and the remote UE to report the link quality of the Uu link, periodically report the link quality, load, and remaining capacity of the PC5 link, or event-triggered reporting, so that the gNB can do more accurate judgment and control.

On the other hand, the remote UE can also receive the link quality situation of the Uu link sent by the relay UE, or the link quality situation of the PC5 link between itself and other remote UEs sent by the relay UE.

That is, in the U2N scenario, the above-mentioned recommended bit rate determination method also includes:

The first relay terminal sends Uu link quality information to the first remote terminal or the network side device, where the Uu link quality information includes the first relay terminal and the network side device Uu link quality information between devices;

and / or,

The first relay terminal sends first PC5 link quality information to the network-side device, where the first PC5 link quality information includes a link between the first relay terminal and the first remote terminal PC5 link quality information between them.

In the above, the first relay terminal can send the Uu link quality information to the first remote terminal or the network side device, and the first relay terminal can send the first PC5 link quality information to the network side device.

In the U2U scenario, the above recommended bit rate determination method also includes:

The first relay terminal sends first PC5 link quality information to the other remote terminals, where the first PC5 link quality information includes the first relay terminal and the first remote terminal PC5 link quality information between;

and / or,

The first relay terminal sends second PC5 link quality information to the first remote terminal, where the second PC5 link quality information includes the first relay terminal and the other remote terminal Link quality information between PC5.

In the above, the first relay terminal may send the first PC5 link quality information to the other remote terminal; the first relay terminal may also send the second PC5 link quality information to the first remote terminal.

At least one of the first recommended bit rate information and the second recommended bit rate information further includes at least one of the following:

Destination address information;

Target remote terminal information;

Target RB identification information.

Between the first remote terminal and the network-side device, and between the first remote terminal and other remote terminals, one relay terminal may be set, or two or more relay terminals may be set. In the end-to-end bit rate recommendation, the sent recommended bit rate message can carry destination address information (also called target address), destination remote terminal information, target RB identification information, etc., for distinction and addressing. The recommended bit rate has been set according to the RB identification granularity of the terminal remote UE. This recommended bit rate is unchanged during the transmission process. After multi-hop transmission and addressing, it finally reaches the remote UE of the terminal.

One relay terminal may be set between the first remote terminal and the network side device, or two or more relay terminals may be set. In the end-to-end bit rate recommendation, the sent recommended bit rate message can carry destination address information (also called target address), destination remote terminal information, target RB identification information, etc., for distinction and addressing. The recommended bit rate has been set according to the RB identification granularity of the terminal remote UE. This recommended bit rate is unchanged during the transmission process. After multi-hop transmission and addressing, it finally reaches the remote UE of the terminal.

Specific embodiments are listed below to illustrate the method for determining the recommended bit rate provided in this application.

The method of the present application can be applied in the secondary link relay architecture, and is an end-to-end recommended bit rate interaction method.

In the U2N architecture, the two final endpoints for end-to-end recommended bit rate control and request are gNB and remote UE.

In the U2U architecture, the two final endpoints for end-to-end recommended bit rate control and request are two remote UEs.

In the L2 architecture, the base station has control over the remote UE and its bearer, that is, the remote UE directly establishes an RRC connection and an end-to-end bearer with the base station, and the end-to-end bearer is carried on the relay UE Uu RLC bearer and the PC5 RLC bearer The bearer and mapping on the network are configured by the base station, and the base station can know the end-to-end RB of each remote UE. For the base station, if it is necessary to control the end-to-end recommended bit rate, the most accurate granularity is to directly control the end-to-end RB of each remote UE, and give the recommended uplink or downlink bit rate. The feasible way can be:

The base station directly sends the recommended bit rate information to each remote UE, and its granularity is based on the end-to-end RB of each remote UE. Since the PDCP layer is based on the end-to-end RB granularity of the remote UE, it can be sent in the form of PDCP control PDU;

The base station first sends the recommended bit rate information to the relay UE, which carries remote UE ID information and end-to-end RB ID information, and the relay UE constructs a PC5 interface message based on the remote UE ID information and E2E RB ID information, and sends it to the remote UE. For example, the Uu interface can use the adaptation layer (adaptation layer) control (control) PDU, RLC control PDU or MAC CE, and then the PC5 interface can use MAC CE signaling or other layer signaling. The granularity of the recommended bit rate is remote UE end-to-end RB;

The remote UE can also request the recommended bit rate to the gNB, and the granularity is also the remote UE end-to-end RB. The feasible method is similar to the above, and the transmission can be performed in the opposite direction. And the remote UE needs to be controlled by the prohibition timer, and cannot frequently request the recommended bit rate.

Similarly, since the relay UE can measure the quality and capacity of the two paths, the relay UE can also request the recommended bit rate of the remote U end-to-end RB granularity to the gNB, for example, Uu MAC CE, RLC control PDU, adaptation layer can be used Control PDU and other formats, carry remote UE ID and end-to-end RB ID information, and request to the base station. The relay UE can also combine multiple remote UE end-to-end RBs mapped to a Uu RLC bearer (bearer), and give an entire recommended bit rate request value based on the Uu LCID.

Due to the control of E2E, in addition to the load and link quality of the Uu link, the load and link quality of the PC5 link also need to be considered, which is equivalent to the capacity and link quality of the end-to-end bearer on the entire transmission path. According to the attainable rate, the final end-to-end recommended bit rate control or request is performed. Therefore, whether it is controlled by gNB or requested by remote UE, it is necessary to grasp the information of the whole path. For example, gNB can request or configure relay UE and The remote UE performs periodic or event-triggered reporting of the link quality of the Uu link, the link quality of the PC5 link, and/or load, remaining capacity, etc., to facilitate more accurate judgment and control by the gNB.

As for the recommended bit rate request on the remote UE side, you can refer to certain Uu link quality and/or load conditions, or the remote UE can directly make a request based on the link quality and/or load conditions of the PC5 link it sees. report.

The Relay UE can also request a recommended bit rate for a remote UE end-to-end RB. It can simultaneously consider the link quality and/or load of the PC5 link and the link quality and/or load of the Uu link, whichever is smaller. Because the smaller link determines the end-to-end capacity, the request is reported.

The gNB can determine the final recommended bit rate after comprehensive consideration according to the received requests from the remote UE and the relay UE.

The L2 U2U architecture can use the end-to-end recommended bit rate control method. The L2 U2U can clearly distinguish the end-to-end bearer and the mapping relationship in each place between two remote UEs. The core of the end-to-end recommended bit rate control is: it The granularity of is end-to-end RB, which can be as follows:

End-to-end PDCP control PDU mode, since the PDCP layer is end-to-end RB granularity, it is more direct and saves additional indication overhead to transmit control messages of this granularity in PDCP control PDU; MAC CE, RLC control PDU or adaptation can also be used The layer control PDU is transmitted. In the control messages of these layers, the remote UE ID and the end-to-end RB ID need to be explicitly carried to distinguish which RB is controlled;

In the end-to-end U2U scenario, any remote UE or relay UE can also request the recommended bit rate to another remote UE node at the end. For example, the remote UE can request the remote UE at the other end in an end-to-end manner. The UE can also make a request to the remote UE at the other end. The request is based on the link capacity currently judged by itself and other link capacities that can be mastered. The smaller of the various capacities is selected, and the end-to-end request is made to report the recommended bit rate for the end-to-end request. The terminal remote UE determines the final end-to-end recommended bit rate control information.

This application provides an end-to-end recommended bit rate interaction method between the remote UE and its serving base station, and between the remote UE and the peer remote UE in the secondary link relay architecture, which can make the remote UE service source coding more efficient It adapts well to the link conditions, improves the transmission efficiency, and guarantees the service experience and system efficiency of the remote UE.
