[0059] The recommended bit rate determination method provided in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0060] Please see Figure 2 , Figure 2 This is a flowchart of a recommended bit rate determination method provided in an embodiment of this application. The recommended bit rate determination method includes:

[0061] Step 201: The first relay terminal performs a first operation, which includes at least one of the following:

[0062] Receive the first recommended bit rate information;

[0063] Send the second recommended bit rate information;

[0064] Wherein, at least one of the first recommended bit rate information and the second recommended bit rate information includes the end-to-end recommended bit rate between the first remote terminal and other remote terminals;

[0065] And / or, at least one of the first recommended bit rate information and the second recommended bit rate information includes the end-to-end recommended bit rate between the first remote terminal and the network-side device.

[0066] Specifically, the first relay terminal can also be called a relay UE. The first relay terminal can be located between the network-side equipment (e.g., a base station) and the first remote terminal (the remote terminal can also be called a remote UE). That is, the network-side equipment and the first remote terminal do not communicate directly, but communicate through the first relay terminal. Alternatively, the first relay terminal can be located between the first remote terminal and other remote terminals. That is, the first remote terminal and other remote terminals do not communicate directly, but communicate through the first relay terminal.

[0067] In the above, the recommended bit rate received or sent by the first relay terminal is an end-to-end recommended bit rate. For example, if the first relay terminal is located between the network-side device and the first remote terminal, the first relay terminal forwards the end-to-end recommended bit rate received between the network-side device and the first remote terminal.

[0068] In this embodiment, the first relay terminal performs a first operation, which includes at least one of the following: receiving first recommended bit rate information; sending second recommended bit rate information; wherein at least one of the first and second recommended bit rate information includes the end-to-end recommended bit rate between the first remote terminal and other remote terminals; and / or, at least one of the first and second recommended bit rate information includes the end-to-end recommended bit rate between the first remote terminal and the network-side device. By transmitting and interacting with the end-to-end recommended bit rate between the first remote terminal and the network-side device, or between the first remote terminal and other remote terminals, through the first relay terminal, the service source encoding of the first remote terminal can better adapt to the link conditions, improve transmission efficiency, and ensure the service experience and system efficiency of the first remote terminal.

[0069] Optionally, prior to step 201, the recommended bit rate determination method may further include: if the first relay terminal is determined to be in a sidelink connection state, determining the network-side device and the first remote terminal that are communicatively connected to the first relay terminal; and / or, determining the first remote terminal and other remote terminals that are communicatively connected to the first relay terminal. It should be noted that the other remote terminal may be a relay terminal or one of the end terminals of the sidelink link.

[0070] In one embodiment of this application, receiving the first recommended bit rate information includes the following:

[0071] Receive first recommended bit rate information sent by the first remote terminal, the first recommended bit rate information including the end-to-end recommended bit rate between the first remote terminal and the network side device, or the end-to-end recommended bit rate between the first remote terminal and other remote terminals;

[0072] Receive first recommended bit rate information sent by the network-side device, the first recommended bit rate information including the end-to-end recommended bit rate between the first remote terminal and the network-side device;

[0073] The system receives first recommended bit rate information sent by the second relay terminal. The first recommended bit rate information includes the end-to-end recommended bit rate between the first remote terminal and the network-side device, or the end-to-end recommended bit rate between the first remote terminal and other remote terminals.

[0074] Specifically, the first relay terminal can receive the first recommended bit rate information sent by the first remote terminal, network-side equipment, or the second relay terminal. The end-to-end recommended bit rate included in the first recommended bit rate information varies depending on the specific circumstances; please refer to the above description for details, which will not be repeated here.

[0075] Correspondingly, the first relay terminal can also send the second recommended bit rate information to the first remote terminal, the network-side device, or the second relay terminal. Specifically, sending the second recommended bit rate information includes the following:

[0076] Send a second recommended bit rate information to the first remote terminal. The second recommended bit rate information includes the end-to-end recommended bit rate between the first remote terminal and the network-side device, or the end-to-end recommended bit rate between the first remote terminal and other remote terminals.

[0077] Send a second recommended bit rate information to the network-side device, the second recommended bit rate information including the end-to-end recommended bit rate between the first remote terminal and the network-side device;

[0078] Send a second recommended bit rate information to the second relay terminal. The second recommended bit rate information includes the end-to-end recommended bit rate between the first remote terminal and the network-side device, or the end-to-end recommended bit rate between the first remote terminal and other remote terminals.

[0079] The end-to-end recommended bit rate included in the second recommended bit rate information varies depending on the circumstances, as detailed in the above description, and will not be repeated here.

[0080] At least one of the first recommended bit rate information and the second recommended bit rate information is transmitted via Packet Data Convergence Protocol (PDCP) Control Protocol Data Unit (PDU), Adaptor Layer Control (PDU), Radio Link Control (RLC) Control (PDU), or Media Access Control (MAC) Control Element (CE) signaling.

[0081] When the first recommended bit rate information is carried in the adaptation layer control PDU, RLC control PDU, or MAC CE signaling, the remote UE identifier and the end-to-end radio bearer (RB) identifier need to be explicitly carried. 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, it includes the second recommended bit rate, the identifier of the first remote terminal, and the second RB identifier; or, it includes the second recommended bit rate, the identifier of the other remote terminal, and the second RB identifier; or, it includes the second recommended bit rate, the identifier of the first remote terminal, the identifier of the other remote terminal, and the second RB identifier.

[0082] And / or, when the second recommended bit rate information is carried in the adaptation layer control PDU, RLC control PDU, or MACCE signaling, the second recommended bit rate information includes the first recommended bit rate, the identifier of the first remote terminal, and the identifier of the first radio bearer RB; or, it includes the second recommended bit rate, the identifier of the first remote terminal, and the identifier of the second RB; or, it includes the second recommended bit rate, the identifier of the other remote terminal, and the identifier of the second RB; or, it includes the second recommended bit rate, the identifier of the first remote terminal, the identifier of the other remote terminal, and the identifier of the second RB.

[0083] Wherein, the first recommended bit rate includes the end-to-end recommended bit rate between the first remote terminal and the network-side device;

[0084] The second recommended bit rate includes the end-to-end recommended bit rate between the first remote terminal and other remote terminals;

[0085] The first RB identifier includes the end-to-end RB identifier between the first remote terminal and the network-side device;

[0086] The second RB identifier includes the end-to-end RB identifier between the first remote terminal and the other remote terminals.

[0087] In the above context, when the first recommended bit rate information includes the end-to-end recommended bit rate between the first remote terminal and other remote terminals, if the first remote terminal is the receiver of the end-to-end recommended bit rate, the first recommended bit rate information includes the identifier of the first remote terminal. If the first remote terminal is the sender of the first recommended bit rate information and the receiver is another remote terminal, then the first recommended bit rate information includes the identifier of the other remote terminal.

[0088] The above also applies to the second recommended bit rate information, which will not be elaborated here.

[0089] It should be noted that the end-to-end recommended bit rate between the first remote terminal and the network-side device, which is included in the first recommended bit rate information, may be the same as or different from the end-to-end recommended bit rate between the first remote terminal and the network-side device, which is included in the second recommended bit rate information.

[0090] The first recommended bit rate information, which includes the end-to-end recommended bit rate between the first remote terminal and other remote terminals, may be the same as or different from the second recommended bit rate information, which includes the end-to-end recommended bit rate between the first remote terminal and other remote terminals.

[0091] In the L2 U2N architecture, end-to-end recommended bit rate control and request processes can be performed. The two final endpoints of control and request are between the gNB and the remote UE. The granularity of control and request can be remote UE end-to-end RB. Intermediate relay nodes can also participate in the request, with the granularity also being remote UE end-to-end RB.

[0092] Regarding the transmission method of control and requests, the path is between the remote UE and the base station, or between the relay UE and the base station. It can be transmitted through PDCP control PDU (remote UE end-to-end RB granularity), or adaptation layer control PDU, RLC control PDU, or MAC CE signaling. When transmitted through adaptation layer control PDU, RLC control PDU, or MAC CE signaling, the remote UE identifier and end-to-end RB identifier need to be explicitly carried. The relay UE can make a request to the gNB based on the request information it receives and its own measurement information of the links on both sides (the Uu link with the base station and the PC5 link with the remote UE), and take the smaller recommended bit rate after comprehensive consideration.

[0093] In the L2 U2U architecture, end-to-end recommended bit rate control and request processes can be performed. The two final endpoints of control and request are between two remote UEs. The granularity of control and request is remote UE end-to-end RB. The relay UE in the middle can also participate in the request, and the granularity is also remote UE end-to-end RB.

[0094] For the transmission method of control and requests, the path is between remote UE1 and the peer remote UE2, or between relay UE and remote UE. It can be transmitted through PDCP control PDU (remote UE end-to-end RB granularity), or adaptation layer control PDU, RLC control PDU, or MAC CE. When transmitted through adaptation layer control PDU, RLC control PDU, or MAC CE signaling, the remote UE identifier and end-to-end RB identifier need to be explicitly carried. Control and requests can have a fixed direction by default, or explicitly carry direction indication, or indication information used to indicate control or requests. The relay UE can make a request to the remote UE based on the request information it receives and its own measurement information of the two links, and then select the recommended bit rate with the smaller value.

[0095] In the above U2U architecture, the two ends of the end-to-end connection 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 identifier of remote UE2, the E2E RB identifier between remote UE1 and remote UE2, and indication information. Optionally, since remote UE1 is the initiating node, remote UE1 can carry the identifier in the addressing information or explicitly include the identifier of remote UE1 in the recommended bit rate information.

[0096] The first recommended bit rate information includes the recommended bit rate of the target object associated with the first remote terminal. In a U2N scenario, the network-side device is the controller, and the remote UE is the requester. In a U2U scenario, the two ends of the communication are one remote UE and another remote UE; the first or second recommended bit rate information also needs to include indication information indicating whether the first remote terminal is the requester or the controller. The requester can also be called the suggester or the receiver, and the controller can also be called the decision-maker or the sender.

[0097] 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, which is used to indicate that the first remote terminal is the controller or the requester.

[0098] The above-mentioned indication information includes at least one of the following:

[0099] A direction identifier bit used to indicate the control direction, which is determined by the first remote terminal as the controlling party or the requesting party based on the control direction;

[0100] An identifier bit used to indicate whether the first remote terminal is the controller or the requester;

[0101] An indication field for indicating the source terminal identifier and the target terminal identifier, wherein the source terminal identifier indicated by the indication field is the identifier of the first remote terminal and the target terminal identifier is the identifier of another terminal, or, the target terminal identifier indicated by the indication field is the identifier of the first remote terminal and the source terminal identifier is the identifier of the other remote terminal.

[0102] Specifically, each direction is clearly identified. For example, remote UE1 -> remote UE2 is designated as direction 1, and remote UE2 -> remote UE1 is designated as direction 2. In direction 1, remote UE1 is the default decision-maker, while remote UE2 is the default suggestion-maker. In direction 2, remote UE2 is the default decision-maker, while remote UE1 is the default suggestion-maker. Direction 1 and direction 2 are the direction identifier bits, which indicate whether remote UE1 or remote UE2 is the controlling party or the requesting party.

[0103] If the signaling direction from remote UE1 to remote UE2 is controlled, the bit is set to 0; if the direction is controlled in the opposite direction, the bit is set to 1. The bit is the direction identifier bit, and the direction identifier bit indicates whether remote UE1 or remote UE2 is the controller or the requester.

[0104] The first recommended bit rate information (or the second recommended bit rate information) can carry source UE ID, target UE ID, and RB ID information. The advantage of this is that the direction and / or control (or request) information is implicit in the source terminal identifier (i.e., source UE ID) and the target terminal identifier (i.e., target UE ID). For example, in the recommended bit rate information sent by remote UE1 to remote UE2, if the source UE ID is the identifier of remote UE1 and the target UE ID is the identifier of remote UE2, then the control direction is remote UE1->remote UE2; if the source UE ID is the identifier of remote UE2 and the target UE ID is the identifier of remote UE1, then the control direction is remote UE2->remote UE1.

[0105] Whether the first remote terminal is the controlling party or the advising party can be determined by default or by explicit indication, such as using a flag bit. For example, it can be carried by one bit; a bit of 0 indicates the controlling party, and a bit of 1 indicates the advising party.

[0106] In the above, the target object includes at least one of the following:

[0107] End-to-end RB identifier;

[0108] PC5 Logical Channel Identifier (LCID);

[0109] Target layer 2 identifier;

[0110] Source layer 2 identifier;

[0111] PC5 link;

[0112] PC5 priority;

[0113] Channel busy rate (CBR) range.

[0114] Since U2U involves two remote UEs, such as the first remote UE and the second remote UE, the following granularity can be used when performing recommended bit rate exchanges:

[0115] Using PC5 LCID granularity: This means that the recommended bit rate is controlled or requested for a PC5 LCID. For the UE at the service source end (the UE at the service source end can be understood as a remote UE), the rate of a logical channel will be set according to this bit rate.

[0116] Using PC5's unique Destination L2 ID granularity: This means that the recommended bit rate is controlled or requested for a specific Destination L2 ID. For the UE at the service source end, the rate sent to a Destination L2 ID will be set according to this bit rate.

[0117] Using PC5's unique Source L2 ID and Destination L2 ID granularity, the recommended bit rate is controlled or requested for a specific Source L2 ID and Destination L2 ID. For the UE at the service source end, the rate from a specific Source L2 ID to a specific Destination L2 ID will be set according to this bit rate.

[0118] Using PC5 link granularity: This means that the recommended bit rate is controlled or requested for a specific PC5 link. The UE at the service source end will set the specific PC5 link transmission rate according to this bit rate.

[0119] Using PC5 priority granularity: This means that the recommended bit rate is controlled or requested for a specific PC5 priority. For the UE at the service source end, the specific PC5 priority transmission rate will be set according to this bit rate.

[0120] The Channel Busy Ratio (CBR) range granularity is used; this means that the recommended bit rate is controlled or requested for a specific CBR range, and the UE at the service source end will set the transmission rate when it is in a specific CBR range according to this bit rate.

[0121] 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 considering the load and link quality of the Uu link, it is also necessary to consider the load and link quality of the PC5 link. This is equivalent to controlling or requesting the final end-to-end recommended bit rate based on the capacity and achievable rate of the end-to-end bearer on the entire transmission path.

[0122] In other words, whether the gNB performs control or the remote UE makes a request, it needs to know the load and link quality of the entire path between the gNB and the remote UE. The gNB can request or configure the relay UE and remote UE to periodically report link quality, PC5 link link quality, load, and remaining capacity, or trigger event-based reporting, to facilitate more accurate judgment and control by the gNB.

[0123] On the other hand, a remote UE can also receive link quality information of the Uu link sent by a relay UE, or link quality information of the PC5 link between the relay UE and other remote UEs sent by the relay UE.

[0124] In the U2N scenario, the above-mentioned recommended bit rate determination method also includes:

[0125] The first relay terminal sends Uu link quality information to the first remote terminal or the network-side device, wherein the Uu link quality information includes the Uu link quality information between the first relay terminal and the network-side device;

[0126] And / or,

[0127] The first relay terminal sends first PC5 link quality information to the network-side device, wherein the first PC5 link quality information includes PC5 link quality information between the first relay terminal and the first remote terminal.

[0128] In the above, the first relay terminal can send 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.

[0129] In U2U scenarios, the above-mentioned recommended bit rate determination method also includes:

[0130] The first relay terminal sends first PC5 link quality information to the other remote terminals, wherein the first PC5 link quality information includes PC5 link quality information between the first relay terminal and the first remote terminal;

[0131] And / or,

[0132] The first relay terminal sends second PC5 link quality information to the first remote terminal, wherein the second PC5 link quality information includes PC5 link quality information between the first relay terminal and the other remote terminal.

[0133] In the above, the first relay terminal can send the first PC5 link quality information to the other remote terminals; the first relay terminal can also send the second PC5 link quality information to the first remote terminal.

[0134] 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:

[0135] Target address information;

[0136] Target remote terminal information;

[0137] Target RB identification information.

[0138] One, two, or more relay terminals can be set up between the first remote terminal and the network-side equipment, as well as between the first remote terminal and other remote terminals. In 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 identifier information, etc., for differentiation and addressing. Since the initial recommended bit rate has been set according to the granularity of the remote UE RB identifier at the final end, this recommended bit rate remains unchanged during transmission. After multiple hops of transmission and addressing, it finally reaches the remote UE at the final end.

[0139] Please see Figure 3 , Figure 3 This is a flowchart of a recommended bit rate determination method provided in an embodiment of this application, such as... Figure 3 As shown, the recommended bit rate determination method provided in this application includes:

[0140] Step 301: The first remote terminal performs a second operation, which includes at least one of the following:

[0141] Send the first recommended bit rate information to the first relay terminal;

[0142] Receive the second recommended bit rate information sent by the first relay terminal;

[0143] Wherein, at least one of the first recommended bit rate information and the second recommended bit rate information includes the end-to-end recommended bit rate between the first remote terminal and the network-side device, or the end-to-end recommended bit rate between the first remote terminal and the other remote terminals.

[0144] Specifically, the first relay terminal may be located between the network-side equipment (e.g., a base station) and the first remote terminal (the remote terminal may also be referred to as a remote UE), that is, the first remote terminal communicates with the network-side equipment through the first relay terminal, or the first relay terminal may be located between the first remote terminal and other remote terminals, and the first remote terminal communicates with other remote terminals through the first relay terminal.

[0145] The first remote terminal sends a first recommended bit rate information to the first relay terminal. The first recommended bit rate information includes the end-to-end recommended bit rate between the first remote terminal and the network-side device, or the end-to-end recommended bit rate between the first remote terminal and the other remote terminals.

[0146] The first remote terminal may also receive the second recommended bit rate information sent by the first relay terminal. The second recommended bit rate information includes the end-to-end recommended bit rate between the first remote terminal and the network-side device, or the end-to-end recommended bit rate between the first remote terminal and the other remote terminals.

[0147] In the above, the recommended bit rate sent by the first relay terminal to the first remote terminal, or the recommended bit rate received by the first relay terminal from the first remote terminal, is an end-to-end recommended bit rate. For example, if the first relay terminal is located between the network-side device and the first remote terminal, the first relay terminal forwards the end-to-end recommended bit rate received between the network-side device and the first remote terminal, and forwards it to the network-side device or the first remote terminal.

[0148] In this embodiment, the first remote terminal performs a second operation, which includes at least one of the following: sending first recommended bit rate information to the first relay terminal; receiving second recommended bit rate information sent by the first relay terminal; wherein at least one of the first recommended bit rate information and the second recommended bit rate information includes the end-to-end recommended bit rate between the first remote terminal and the network-side device, or the end-to-end recommended bit rate between the first remote terminal and other remote terminals. By having the first relay terminal transmit and interact with the end-to-end recommended bit rate between the first remote terminal and the network-side device, or between the first remote terminal and other remote terminals, the service source encoding of the first remote terminal can better adapt to the link conditions, improve transmission efficiency, and ensure the service experience and system efficiency of the first remote terminal.

[0149] The first remote terminal cannot frequently request the recommended bit rate and needs to be controlled by a disable timer. That is, when the first recommended bit rate information includes the end-to-end recommended bit rate between the first remote terminal and the network-side device, after the first remote terminal sends the first recommended bit rate information to the first relay terminal, the method further includes:

[0150] The first remote terminal starts a disable timer, which is used to prevent the first remote terminal from sending the end-to-end recommended bit rate to the network-side device.

[0151] For example, after a remote UE reports the end-to-end recommended bit rate to the base station once, it will start a disable timer. During the operation of the disable timer, it is not allowed to report again until the timer expires, at which point it can report again.

[0152] At least one of the first recommended bit rate information and the second recommended bit rate information is transmitted via PDCP control PDU, adaptation layer control PDU, RLC control PDU, or MAC CE signaling.

[0153] When the first recommended bit rate information is carried in the adaptation layer control PDU, RLC control PDU, or MAC CE signaling, the remote UE identifier and the end-to-end radio bearer (RB) identifier need to be explicitly carried. 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, it includes the second recommended bit rate, the identifier of the other remote terminal, and the second RB identifier; or, it includes the second recommended bit rate, the identifier of the first remote terminal, the identifier of the other remote terminal, and the second RB identifier.

[0154] And / or, when the second recommended bit rate information is carried in the adaptation layer control PDU, RLC control PDU, or MACCE signaling, the second recommended bit rate information includes the first recommended bit rate, the identifier of the first remote terminal, and the identifier of the first radio bearer RB; or, it includes the second recommended bit rate, the identifier of the other remote terminal, and the identifier of the second RB; or, it includes the second recommended bit rate, the identifier of the first remote terminal, the identifier of the other remote terminal, and the identifier of the second RB.

[0155] Wherein, the first recommended bit rate includes the end-to-end recommended bit rate between the first remote terminal and the network-side device;

[0156] The second recommended bit rate includes the end-to-end recommended bit rate between the first remote terminal and other remote terminals;

[0157] The first RB identifier includes the end-to-end RB identifier between the first remote terminal and the network-side device;

[0158] The second RB identifier includes the end-to-end RB identifier between the first remote terminal and the other remote terminals.

[0159] The end-to-end recommended bit rate in the first recommended bit rate information and the end-to-end recommended bit rate in the second recommended bit rate information may be the same or different.

[0160] At least one of the first recommended bit rate information and the second recommended bit rate information includes:

[0161] The recommended bit rate of the target object associated with the first remote terminal.

[0162] In a U2U scenario, the two ends of the communication are one remote UE and another remote UE. The first or second recommended bit rate information also needs to include indication information indicating whether the first remote terminal is a requester or a controller. The requester can also be called a suggester or a receiver, and the controller can also be called a decision-maker or a sender. That is, at least one of the first and second recommended bit rate information further includes indication information used to indicate whether the first remote terminal is a controller or a requester.

[0163] The above-mentioned indication information includes at least one of the following:

[0164] A direction identifier bit used to indicate the control direction, which is determined by the first remote terminal as the controlling party or the requesting party based on the control direction;

[0165] An identifier bit used to indicate whether the first remote terminal is the controller or the requester;

[0166] An indication field for indicating the source terminal identifier and the target terminal identifier, wherein the source terminal identifier indicated by the indication field is the identifier of the first remote terminal and the target terminal identifier is the identifier of another terminal, or, the target terminal identifier indicated by the indication field is the identifier of the first remote terminal and the source terminal identifier is the identifier of the other remote terminal.

[0167] The target object includes at least one of the following:

[0168] End-to-end radio bearer (RB) identifier;

[0169] PC5 Logical Channel Identifier (LCID);

[0170] Target layer 2 identifier;

[0171] Source layer 2 identifier;

[0172] PC5 link;

[0173] PC5 priority;

[0174] Channel busy rate (CBR) range.

[0175] 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 considering the load and link quality of the Uu link, it is also necessary to consider the load and link quality of the PC5 link. This is equivalent to controlling or requesting the final end-to-end recommended bit rate based on the capacity and achievable rate of the end-to-end bearer on the entire transmission path.

[0176] In other words, whether the gNB performs control or the remote UE makes a request, it needs to know the load and link quality of the entire path between the gNB and the remote UE. The gNB can request or configure the relay UE and remote UE to periodically report link quality, PC5 link link quality, load, and remaining capacity, or trigger event-based reporting, to facilitate more accurate judgment and control by the gNB.

[0177] On the other hand, a remote UE can also receive link quality information of the Uu link sent by a relay UE, or link quality information of the PC5 link between the relay UE and other remote UEs sent by the relay UE.

[0178] In the U2N scenario, the above-mentioned recommended bit rate determination method further includes: the first remote terminal receiving Uu link quality information sent by the first relay terminal, wherein the Uu link quality information includes the Uu link quality information between the first relay terminal and the network-side device.

[0179] In the above, the first relay terminal can send Uu link quality information to the first remote terminal so that the first remote terminal can know the Uu link quality status.

[0180] In U2U scenarios, the above-mentioned recommended bit rate determination method also includes:

[0181] The first remote terminal receives the second PC5 link quality information sent by the first relay terminal, wherein the second PC5 link quality information includes the PC5 link quality information between the first relay terminal and the other remote terminals.

[0182] The first remote terminal communicates with other remote terminals. The first relay terminal sends the quality information of the second PC5 link to the first remote terminal so that the first remote terminal can know the quality status of the second PC5 link.

[0183] 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:

[0184] Target address information;

[0185] Target remote terminal information;

[0186] Target RB identification information.

[0187] One, two, or more relay terminals can be set up between the first remote terminal and other remote terminals. In end-to-end bit rate recommendation, the recommended bit rate message sent can carry destination address information (also called target address), destination remote terminal information, target RB identifier information, etc., for differentiation and addressing. Since the initial recommended bit rate has been set according to the granularity of the remote UE RB identifier at the final end, this recommended bit rate remains unchanged during transmission. After multiple hops of transmission and addressing, it finally reaches the final remote UE.

[0188] Please see Figure 4 , Figure 4 This is a flowchart of a recommended bit rate determination method provided in an embodiment of this application, such as... Figure 4 As shown, the recommended bit rate determination method provided in this application includes:

[0189] Step 401: The network-side device performs a third operation, which includes at least one of the following:

[0190] Send the first recommended bit rate information to the first relay terminal;

[0191] Receive the second recommended bit rate information sent by the first relay terminal;

[0192] Wherein, at least one of the first recommended bit rate information and the second recommended bit rate information includes the end-to-end recommended bit rate between the first remote terminal and the network-side device.

[0193] In the above, by transmitting and interacting with the end-to-end recommended bit rate between the first remote terminal and the network-side equipment through the first relay terminal, the service source encoding of the first remote terminal can better adapt to the link conditions, improve transmission efficiency, and ensure the service experience and system efficiency of the first remote terminal.

[0194] At least one of the first recommended bit rate information and the second recommended bit rate information is transmitted via Packet Data Convergence Protocol (PDCP) Control Protocol Data Unit (PDU), Adaptor Layer Control Unit (PDU), Radio Link Layer Control Unit (RLC) Control Unit (PDU), or Media Access Control (MAC) Control Element (CE) signaling.

[0195] When the first recommended bit rate information is carried in the adaptation layer control PDU, RLC control PDU, or MAC CE signaling, the first recommended bit rate information includes the first recommended bit rate, the identifier of the first remote terminal, and the identifier of the first radio bearer RB.

[0196] And / or,

[0197] When the second recommended bit rate information is carried in the adaptation layer control PDU, RLC control PDU, or MAC CE signaling, the second recommended bit rate information includes the first recommended bit rate, the identifier of the first remote terminal, and the first RB identifier;

[0198] Wherein, the first recommended bit rate includes the end-to-end recommended bit rate between the first remote terminal and the network-side device;

[0199] The first RB identifier includes the end-to-end RB identifier between the first remote terminal and the network-side device.

[0200] At least one of the first recommended bit rate information and the second recommended bit rate information includes:

[0201] The recommended bit rate of the target object associated with the first remote terminal.

[0202] The target object includes at least one of the following:

[0203] End-to-end RB identifier;

[0204] PC5 LCID;

[0205] Target layer 2 identifier;

[0206] Source layer 2 identifier;

[0207] PC5 link;

[0208] PC5 priority;

[0209] Channel Busy Rate (CBR) range.

[0210] 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 considering the load and link quality of the Uu link, it is also necessary to consider the load and link quality of the PC5 link. This is equivalent to controlling or requesting the final end-to-end recommended bit rate based on the capacity and achievable rate of the end-to-end bearer on the entire transmission path.

[0211] In other words, whether the gNB performs control or the remote UE makes a request, it needs to know the load and link quality of the entire path between the gNB and the remote UE. The gNB can request or configure the relay UE and remote UE to periodically report link quality, PC5 link link quality, load, and remaining capacity, or trigger event-based reporting, to facilitate more accurate judgment and control by the gNB.

[0212] In the U2N scenario, the above-mentioned recommended bit rate determination method also includes:

[0213] The network-side device receives Uu link quality information sent by the first relay terminal, wherein the Uu link quality information includes Uu link quality information between the first relay terminal and the network-side device;

[0214] And / or,

[0215] The network-side device receives the first PC5 link quality information sent by the first relay terminal, wherein the first PC5 link quality information includes the PC5 link quality information between the first relay terminal and the first remote terminal.

[0216] 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:

[0217] Target address information;

[0218] Target remote terminal information;

[0219] Target RB identification information.

[0220] One, two, or more relay terminals can be set up between the first remote terminal and the network-side equipment. In end-to-end bit rate recommendation, the sent recommended bit rate message can carry destination address information (also known as target address), destination remote terminal information, target RB identifier information, etc., for differentiation and addressing. Since the initial recommended bit rate has been set according to the granularity of the remote UE RB identifier at the final end, this recommended bit rate remains unchanged during transmission. After multiple hops of transmission and addressing, it finally reaches the final remote UE.

[0221] The following specific embodiments illustrate the recommended bit rate determination method provided in this application.

[0222] The method described in this application can be applied to secondary link relay architectures and is an end-to-end recommended bit rate interaction method.

[0223] In the U2N architecture, the two final endpoints for end-to-end recommended bit rate control and requests are gNB and remoteUE.

[0224] In the U2U architecture, the two final endpoints for end-to-end recommended bit rate control and requests are two remoteUEs.

[0225] In the L2 architecture, the base station has control over the remote UE and its bearers. Specifically, the remote UE establishes a direct RRC connection and end-to-end bearer with the base station. The end-to-end bearer's bearer configuration and mapping on the relay UE's Uu RLC bearer and PC5 RLC bearer are configured by the base station, which has access to the end-to-end RBs for each remote UE. For the base station to control the end-to-end recommended bit rate, the most precise granularity is to directly control the end-to-end RBs of each remote UE, providing a recommended uplink or downlink bit rate. Feasible methods include:

[0226] The base station directly sends the recommended bit rate information to each remote UE. The 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, the PDCP can be used to control the PDU for transmission.

[0227] The base station first sends the recommended bit rate information to the relay UE, which carries the remote UE ID information and the end-to-end RB ID information. The relay UE then constructs a PC5 interface message based on the remote UE ID information and the E2E RB ID information and sends it to the remote UE. For example, the Uu interface can use an adaptation layer 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 the end-to-end RB of the remote UE.

[0228] The remote UE can also request a recommended bit rate from the gNB, with the granularity being end-to-end RB from the remote UE. The feasible method is similar to the above, simply transmitting in the reverse direction. However, the remote UE needs to be controlled by a disable timer to prevent frequent requests for the recommended bit rate.

[0229] Similarly, since relay UEs can measure the quality and capacity of two paths, they can also request recommended bit rates at the remote U end-to-end RB granularity from the gNB. For example, they can use formats such as Uu MAC CE, RLC control PDU, or adaptation layer control PDU, carrying the remote UE ID and end-to-end RB ID information, to request the base station. A relay UE can also merge end-to-end RB requests from multiple remote UEs mapped to a single Uu RLC bearer, providing a single recommended bit rate request value based on the Uu LCID.

[0230] Due to E2E control, in addition to considering the load and link quality of the Uu link, it is also necessary to consider the load and link quality of the PC5 link. This is equivalent to controlling or requesting the final end-to-end recommended bit rate based on the capacity and achievable rate of the end-to-end bearer throughout the entire transmission path. Therefore, whether the gNB performs the control or the remote UE makes the request, it needs to have information about the entire path. For example, the gNB can request or configure the relay UE and remote UE to periodically or event-triggeredly report the link quality of the Uu link, the link quality of the PC5 link, and / or the load, remaining capacity, etc., respectively, so that the gNB can make more accurate judgments and controls.

[0231] As for the recommended bit rate request on the remote UE side, it can refer to certain Uu link quality and / or load conditions, or the remote UE can directly request and report based solely on the link quality and / or load conditions of the PC5 link it sees.

[0232] Relay UEs can also make recommended bit rate requests for an end-to-end RB for a remote UE. They can simultaneously consider the link quality and / or load of the PC5 link and the link quality and / or load of the Uu link, taking the smaller value, because the smaller link segment determines the end-to-end capacity, and then report the request.

[0233] The gNB can determine the final recommended bit rate by comprehensively considering the requests received from remote UEs and relay UEs.

[0234] The L2 U2U architecture can use end-to-end recommended bit rate control. L2 U2U allows two remote UEs to clearly distinguish the end-to-end bearer and the mapping relationship at each point. The core of end-to-end recommended bit rate control is that its granularity is end-to-end RB, which can be done in the following ways:

[0235] In the end-to-end PDCP control PDU mode, since the PDCP layer is at the end-to-end RB granularity, it is more direct and saves additional indication overhead to transmit control messages at this granularity in the PDCP control PDU. Alternatively, it can be transmitted in the form of MAC CE, RLC control PDU or adaptation layer control PDU. In the control messages of these layers, the remote UE ID and end-to-end RB ID need to be explicitly carried to distinguish which RB is being controlled.

[0236] In an end-to-end U2U scenario, any remote UE or relay UE can request a recommended bit rate from another remote UE node at the final end. For example, a remote UE can request a recommended bit rate from another remote UE in an end-to-end manner, and a relay UE can also request a recommended bit rate from another remote UE. The request is based on a comprehensive consideration of the current link capacity and other available link capacities, taking the smaller of the various capacities to report the recommended bit rate at the end end, so that the final remote UE can determine the final end-to-end recommended bit rate control information.

[0237] This application provides a method for end-to-end recommended bit rate interaction between a remote UE and its serving base station, and between a remote UE and a peer remote UE in a secondary link relay architecture. This method enables the remote UE's service source coding to better adapt to the link conditions, improves transmission efficiency, and ensures the service experience and system efficiency of the remote UE.
