[0124] In the embodiments of the present disclosure, the term “and / or” describes the association relationship of the associated objects, which means that there can be three relationships, for example, A and / or B, which can represent the three cases of A alone, A and B together, and B alone. The character “ / ” generally represents an “or” relationship between the associated objects before and after it.

[0125] In the embodiments of the present disclosure, the term “multiple” means two or more, and other quantifiers are similar.

[0126] The technical solutions provided by the embodiments of the present disclosure can be applied to various systems, such as a 5G system.

[0127] In different systems, the terminal can also be referred to by different names. For example, in a 5G system, the terminal can be referred to as a user equipment (UE). The wireless terminal device can communicate with one or more core networks (CN) via a radio access network (RAN). The wireless terminal device can be a mobile terminal device, such as a mobile phone (also known as a "cellular" phone) and a computer with a mobile terminal device, for example, a portable, pocket, handheld, computer-embedded, or vehicle-mounted mobile device that exchanges voice and / or data with a radio access network. For example, personal communication service (PCS) phones, cordless phones, session initiated protocol (SIP) phones, wireless local loop (WLL) stations, personal digital assistants (PDAs), and the like. The wireless terminal device can also be referred to as a system, a subscriber unit, a subscriber station, a mobile station, a mobile, a remote station, an access point, a remote terminal, an access terminal, a user terminal, a user agent, a user device, and the like, and is not limited in the present embodiment.

[0128] The network device related to the embodiments of the present disclosure can be a base station, which can include a plurality of cells serving terminals. According to different application scenarios, the base station can also be referred to as an access point, or can be a device in an access network that communicates with wireless terminal devices through one or more sectors over an air interface, or other names. The network device can be used to exchange received air frames and Internet Protocol (IP) packets as a router between the wireless terminal device and the rest of the access network, which can include an Internet Protocol (IP) communication network. The network device can also coordinate the management of the properties of the air interface. For example, the network device related to the embodiments of the present disclosure can be a network device (Base Transceiver Station, BTS) in the Global System for Mobile Communications (GSM) or Code Division Multiple Access (CDMA), and can also be a network device (NodeB) in Wide-band Code Division Multiple Access (WCDMA), and can also be an evolved network device (evolutional Node B, eNB or e-NodeB) in a long term evolution (LTE) system, a 5G base station (gNB) in a next generation system (5G network architecture), and can also be a home evolved Node B (HeNB), a relay node, a femto, a pico, etc., which are not limited in the embodiments of the present disclosure. In some network structures, the network device can include a centralized unit (CU) node and a distributed unit (DU) node, and the centralized unit and the distributed unit can also be arranged geographically apart.

[0129] For example, in the embodiments of the present disclosure, the network device and the terminal device can each use one or more antennas for Multi Input Multi Output (MIMO) transmission, which can be Single User MIMO (SU-MIMO) or Multiple User MIMO (MU-MIMO). According to the form and number of root antenna combinations, the MIMO transmission can be 2D-MIMO, 3D-MIMO, FD-MIMO or massive-MIMO, or can be diversity transmission or precoding transmission or beamforming transmission, etc.

[0130] The technical solutions provided by the embodiments of the present disclosure can be applied in a multi-hop relay scenario. In order to expand the network coverage, the concept of relay is introduced. The relay itself can be a terminal with relay function. Generally, the terminal being relayed, i.e. the communication interface between the remote terminal and the relay terminal is a Sidelink interface, i.e. a direct communication interface or a bypass interface or a PC5 interface; the communication interface between the relay terminal and the network device is a Uu interface.

[0131] For example, referring to FIG. 1, FIG. 1 is a schematic diagram of a multi-hop relay link scenario provided by the embodiments of the present disclosure, wherein the remote terminal interacts with the network device through the relay terminal A, the relay terminal B and the relay terminal C.

[0132] Among them, the communication interface between the remote terminal and the relay terminal A is a Sidelink interface, the communication interface between the relay terminal A and the relay terminal B is a Sidelink interface, the communication interface between the relay terminal B and the relay terminal C is a Sidelink interface, and the communication interface between the relay terminal C and the network device is a Uu interface.

[0133] In the multi-hop relay scenario, due to the difference in protocol stack architecture, it is generally divided into L2 multi-hop relay and L3 multi-hop relay. In the L2 multi-hop relay scenario, the remote terminal will establish an end-to-end Radio Resource Control (RRC) connection between the network device. However, in the L3 multi-hop relay scenario, there is no end-to-end RRC connection between the remote terminal and the network device.

[0134] Therefore, in the L2 multi-hop relay scenario, how to determine the QoS parameters used by each hop of the direct communication interface, so as to ensure the end-to-end QoS of the service in the multi-hop relay scenario, is a technical problem that those skilled in the art need to solve.

[0135] In order to determine the QoS parameter used by each hop direct communication interface, so as to ensure the end-to-end QoS of services in the multi-hop relay scenario, the embodiment of the present disclosure provides a service quality QoS parameter configuration method. In the following, the technical solutions in the embodiments of the present disclosure will be clearly and completely described in combination with the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only a part of the embodiments of the present disclosure, not all the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present disclosure.

[0136] FIG. 2 is a flowchart of a service quality QoS parameter configuration method provided by an embodiment of the present disclosure, applied to a terminal. As shown in FIG. 2, the method can include:

[0137] S201, receiving first configuration information sent by a network device, the first configuration information including at least one of the following:

[0138] a first QoS parameter corresponding to a first target object between the terminal and a next-hop relay terminal of the terminal in a first transmission direction;

[0139] a second QoS parameter corresponding to a second target object between the terminal and a next-hop terminal of the terminal in a second transmission direction, the next-hop terminal being a remote terminal or a relay terminal;

[0140] a first total QoS parameter used by a third target object when transmitting between a remote terminal and a target relay terminal in the first transmission direction, the target relay terminal being a relay terminal connected to the network device through a Uu interface;

[0141] a second total QoS parameter used by a fourth target object when transmitting between a first relay terminal in the second transmission direction and a remote terminal in the second transmission direction;

[0142] Wherein, the first transmission direction is an uplink transmission direction or a transmission direction from the remote terminal to the network device, and the second transmission direction is a downlink transmission direction or a transmission direction from the network device to the remote terminal.

[0143] The first target object or the second target object includes at least one of the following:

[0144] a logical channel of the direct communication interface;

[0145] a radio link control channel of the direct communication interface, a quality of service flow QoS flow identifier of the direct communication interface;

[0146] a quality of service profile QoS profile of the direct communication interface;

[0147] a QoS profile identity of the direct communication interface;

[0148] The third target object or the fourth target object comprises at least one of:

[0149] An end-to-end bearer between the remote terminal and the network device;

[0150] An end-to-end QoS flow identity between the remote terminal and the network device;

[0151] An end-to-end QoS profile between the remote terminal and the network device;

[0152] An end-to-end QoS profile identity between the remote terminal and the network device.

[0153] For example, in the embodiments of the present disclosure, the QoS parameter comprises at least one of:

[0154] A packet delay budget;

[0155] A packet error rate;

[0156] A packet data unit set delay budget;

[0157] A packet data unit set error rate.

[0158] It can be seen that, in the embodiments of the present disclosure, the terminal receives the first configuration information sent by the network device, and the first configuration information comprises at least one of: a first QoS parameter corresponding to a first target object between the terminal and a next-hop relay terminal in a first transmission direction; a second QoS parameter corresponding to a second target object between the terminal and a next-hop terminal in a second transmission direction, the next-hop terminal being a remote terminal or a relay terminal; a first total QoS parameter used by a third target object when being transmitted between the remote terminal and a target relay terminal in the first transmission direction, the target relay terminal being a relay terminal having a Uu interface connection with the network device; and a second total QoS parameter used by a fourth target object when being transmitted between a first relay terminal in the second transmission direction and the remote terminal in the second transmission direction, so that the QoS parameter used by each hop of the direct communication interface can be determined through the first configuration information, thereby ensuring the end-to-end QoS of the service in the multi-hop relay scenario.

[0159] For example, in the embodiments of the present disclosure, in a possible scenario, the terminal can be a remote terminal or a relay terminal on a multi-hop link, and specifically, the relay terminal on the multi-hop relay link can refer to any relay terminal on the multi-hop relay link. The first configuration information received by the terminal can comprise a first QoS parameter corresponding to a first target object between the terminal and a next-hop relay terminal in a first transmission direction.

[0160] The first transmission direction is an uplink transmission direction or a transmission direction from the remote terminal to the network device.

[0161] For example, in the possible scenario shown in FIG. 1, when the terminal is a remote terminal, the first configuration information received by the terminal can be a first QoS parameter corresponding to a direct communication interface object between the remote terminal and the relay terminal in the first transmission direction, so that the remote terminal performs data transmission in the first transmission direction between the remote terminal and the relay terminal A by using the first QoS parameter; when the terminal is the relay terminal A, the first configuration information received by the terminal can be a first QoS parameter corresponding to a direct communication interface object between the relay terminal A and the relay terminal B in the first transmission direction, so that the relay terminal A performs data transmission in the first transmission direction between the remote terminal and the relay terminal B by using the first QoS parameter; when the terminal is the relay terminal B, the first configuration information received by the terminal can be a first QoS parameter corresponding to a direct communication interface object between the relay terminal B and the relay terminal C in the first transmission direction, so that the relay terminal B performs data transmission in the first transmission direction between the relay terminal B and the relay terminal C by using the first QoS parameter; and when the terminal is the relay terminal C, the first configuration information received by the terminal can be a first QoS parameter corresponding to a Uu interface object between the relay terminal C and the network device in the first transmission direction, so that the relay terminal C performs data transmission in the first transmission direction between the relay terminal C and the network device by using the first QoS parameter. In this way, the QoS parameter used by each hop direct communication interface can be determined, so as to guarantee the end-to-end QoS of the service in the multi-hop relay scenario.

[0162] In another possible scenario, the terminal can be a relay terminal on a multi-hop link. Specifically, the relay terminal on the multi-hop relay link can be any relay terminal on the multi-hop relay link. The first configuration information received by the terminal can include a first QoS parameter corresponding to a direct communication interface object between the terminal and a next-hop terminal of the terminal in a second transmission direction, the next-hop terminal being a remote terminal or a relay terminal.

[0163] The second transmission direction is a downlink transmission direction or a transmission direction from the network device to the remote terminal.

[0164] For example, in the possible scenario shown in FIG. 1, in the case that the terminal is the relay terminal A, the first configuration information received by the terminal can be the first QoS parameter corresponding to the direct communication interface object between the relay terminal A and the remote terminal in the second transmission direction, so that the relay terminal A performs data transmission in the second transmission direction between the relay terminal A and the remote terminal by using the first QoS parameter; in the case that the terminal is the relay terminal B, the first configuration information received by the terminal can be the first QoS parameter corresponding to the direct communication interface object between the relay terminal B and the relay terminal A in the second transmission direction, so that the relay terminal B performs data transmission in the second transmission direction between the relay terminal B and the relay terminal A by using the first QoS parameter; in the case that the terminal is the relay terminal C, the first configuration information received by the terminal can be the first QoS parameter corresponding to the direct communication interface object between the relay terminal C and the relay terminal B in the second transmission direction, so that the relay terminal C performs data transmission in the first transmission direction between the relay terminal C and the relay terminal B by using the first QoS parameter, which can determine the QoS parameter used by each hop direct communication interface, thereby guaranteeing the end-to-end QoS of the service in the multi-hop relay scenario.

[0165] In another possible scenario, the terminal can be a remote terminal or a first relay terminal, the first relay terminal being a relay terminal connected with the remote terminal through a direct communication interface, and the first configuration information received by the terminal can include a first total QoS parameter used by the third target object when performing transmission between the remote terminal and a target relay terminal in the first transmission direction, the target relay terminal being a relay terminal connected with the network device through a Uu interface.

[0166] The first transmission direction is an uplink transmission direction or a transmission direction from the remote terminal to the network device.

[0167] For example, in the embodiments of the present disclosure, in the case that the terminal is a remote terminal or a first relay terminal, the first total QoS parameter can include a total QoS parameter used between the remote terminal and the target relay terminal in the first transmission direction, and the first relay terminal is a relay terminal connected with the remote terminal through a direct communication interface.

[0168] For example, in the embodiments of the present disclosure, in the case that the terminal is a remote terminal or a first relay terminal, the terminal receives a first notification message from a second node, and the first notification message includes the first total QoS parameter, the second node being a network device or a remote terminal. Specifically, in the case that the terminal is a remote terminal, the second node is a network device; and in the case that the terminal is a first relay terminal, the second node is a network device or a remote terminal.

[0169] For example, in the embodiment of the present disclosure, when the terminal is a remote terminal or a first relay terminal, the terminal can receive a first notification message from the second node, and the first notification message includes a first total QoS parameter used by the third target object when transmitting between the remote terminal and the target relay terminal in the first transmission direction. For example, in combination with FIG. 1, the first total QoS parameter is the total QoS parameter used by the third target object when transmitting between the remote terminal and the relay terminal C in the first transmission direction.

[0170] For example, in the embodiment of the present disclosure, when the terminal is a first relay terminal, and the first configuration information includes a first total QoS parameter used by the third target object when transmitting between the remote terminal and the target relay terminal in the first transmission direction, the first relay terminal can further split the first total QoS parameter to determine a QoS parameter used by the third target object when transmitting between the remote terminal and the terminal in the first transmission direction, and a remaining QoS parameter used by the third target object when transmitting between the terminal and the target relay terminal.

[0171] For example, in the embodiment of the present disclosure, when the terminal is a first relay terminal, after the terminal splits the first total QoS parameter, the terminal can further send a second notification message to the remote terminal, and the second notification message includes the QoS parameter used by the third target object when transmitting between the remote terminal and the terminal in the first transmission direction.

[0172] And / or,

[0173] The third notification message is sent to the next hop relay terminal of the terminal, and the third notification message includes the remaining QoS parameter used by the third target object when transmitting between the terminal and the target relay terminal in the first transmission direction.

[0174] For example, in combination with FIG. 1, when the terminal is the relay terminal A, and the first configuration information includes a first total QoS parameter used by the third target object when transmitting between the remote terminal and the relay terminal C in the first transmission direction, the relay terminal A can further split the first total QoS parameter to determine a QoS parameter used by the third target object when transmitting between the remote terminal and the relay terminal A in the first transmission direction, and a remaining QoS parameter used by the third target object when transmitting between the relay terminal A and the relay terminal C.

[0175] For example, in the embodiment of the present disclosure, after the relay terminal A splits the first total QoS parameter, the relay terminal A can further send a second notification message to the remote terminal, and the second notification message includes the QoS parameter used by the third target object when transmitting between the remote terminal and the terminal in the first transmission direction.

[0176] And / or,

[0177] The terminal sends a third notification message to a next-hop relay terminal, i.e., relay terminal B, the third notification message including the remaining QoS parameters used by the third target object in the transmission between the relay terminal A and the target relay terminal in the first transmission direction, to determine the QoS parameters used by each hop direct communication interface, so as to guarantee the end-to-end QoS of the service in the multi-hop relay scenario.

[0178] For example, in combination with FIG. 1, in the case that the terminal is a remote terminal, the first configuration information includes the first total QoS parameters used by the third target object in the transmission between the remote terminal and relay terminal C in the first transmission direction, the remote terminal can receive the first total QoS parameters from the network device, and send the first total QoS parameters to the relay terminal A; the relay terminal A splits the first total QoS parameters, determines the QoS parameters used by the third target object in the transmission between the remote terminal and the relay terminal A in the first transmission direction, and the remaining QoS parameters used by the third target object in the transmission between the relay terminal A and the relay terminal C.

[0179] For example, in the embodiment of the present disclosure, after the relay terminal A splits the first total QoS parameters, the relay terminal A can also send a second notification message to the remote terminal, the second notification message including the QoS parameters used by the third target object in the transmission between the remote terminal and the terminal in the first transmission direction.

[0180] And / or,

[0181] The terminal sends a third notification message to a next-hop relay terminal, i.e., relay terminal B, the third notification message including the remaining QoS parameters used by the third target object in the transmission between the relay terminal A and the target relay terminal in the first transmission direction, to determine the QoS parameters used by each hop direct communication interface, so as to guarantee the end-to-end QoS of the service in the multi-hop relay scenario.

[0182] In another possible scenario, the terminal can be the first relay terminal or the second relay terminal in the second transmission direction, and the first configuration information received by the terminal can include the second total QoS parameters used by the fourth target object in the transmission between the first relay terminal in the second transmission direction and the remote terminal in the second transmission direction.

[0183] The second transmission direction is a downlink transmission direction or a transmission direction from the network device to the remote terminal.

[0184] For example, in the embodiment of the present disclosure, in the case that the terminal is the first relay terminal or the second relay terminal in the second transmission direction, the second total QoS parameters can include the total QoS parameters used by the first relay terminal in the transmission between the first relay terminal and the remote terminal in the second transmission direction.

[0185] For example, in the embodiment of the present disclosure, when the terminal is the first relay terminal or the second relay terminal in the second transmission direction, the terminal can receive a fourth notification message from a third node, the fourth notification message comprising a second total QoS parameter, the third node being a network device or the first relay terminal in the second transmission direction. Specifically, when the terminal is the first relay terminal, the third node is the network device; when the terminal is the second relay terminal, the second node is the network device or the first relay terminal.

[0186] For example, in the embodiment of the present disclosure, when the terminal is the first relay terminal or the second relay terminal in the second transmission direction, the terminal receives a fourth notification message from a third node, the fourth notification message comprising a second total QoS parameter used by the fourth target object when transmitting between the first relay terminal and the remote terminal in the second transmission direction. For example, in combination with FIG. 1, the second total QoS parameter is the total QoS parameter used by the fourth target object when transmitting between the relay terminal C and the remote terminal in the second transmission direction.

[0187] For example, in the embodiment of the present disclosure, when the terminal is the second relay terminal, and the first configuration information comprises the second total QoS parameter used by the fourth target object when transmitting between the first relay terminal and the remote terminal in the second transmission direction, the second relay terminal can further split the second total QoS parameter to determine the QoS parameter used by the fourth target object when transmitting between the first relay terminal and the second relay terminal in the second transmission direction, and the remaining QoS parameter used by the fourth target object when transmitting between the second relay terminal and the remote terminal in the second transmission direction.

[0188] For example, in the embodiment of the present disclosure, when the terminal is the second relay terminal, after splitting the second total QoS parameter, the terminal can further send a fifth notification message to the first relay terminal, the fifth notification message comprising the QoS parameter used by the fourth target object when transmitting between the first relay terminal and the terminal in the second transmission direction.

[0189] and / or,

[0190] send a sixth notification message to the next hop relay terminal of the terminal, the sixth notification message comprising the remaining QoS parameter used by the fourth target object when transmitting between the terminal and the remote terminal in the second transmission direction.

[0191] For example, in the case that the terminal is the relay terminal B, the first configuration information includes the second total QoS parameter used by the relay terminal C to the remote terminal in the second transmission direction, the relay terminal B can further split the second total QoS parameter to determine the QoS parameter used by the fourth target object between the relay terminal C and the relay terminal B in the second transmission direction and the remaining QoS parameter used by the fourth target object between the relay terminal B and the remote terminal in the second transmission direction.

[0192] For example, in the case that the terminal is the relay terminal B, the first configuration information includes the second total QoS parameter used by the relay terminal C to the remote terminal in the second transmission direction, the relay terminal B can further split the second total QoS parameter to determine the QoS parameter used by the fourth target object between the relay terminal C and the relay terminal B in the second transmission direction and the remaining QoS parameter used by the fourth target object between the relay terminal B and the remote terminal in the second transmission direction.

[0193] For example, in the case that the terminal is the relay terminal B, the first configuration information includes the second total QoS parameter used by the relay terminal C to the remote terminal in the second transmission direction, the relay terminal B can further split the second total QoS parameter to determine the QoS parameter used by the fourth target object between the relay terminal C and the relay terminal B in the second transmission direction and the remaining QoS parameter used by the fourth target object between the relay terminal B and the remote terminal in the second transmission direction.

[0194] For example, in the case that the terminal is the relay terminal B, the first configuration information includes the second total QoS parameter used by the relay terminal C to the remote terminal in the second transmission direction, the relay terminal B can further split the second total QoS parameter to determine the QoS parameter used by the fourth target object between the relay terminal C and the relay terminal B in the second transmission direction and the remaining QoS parameter used by the fourth target object between the relay terminal B and the remote terminal in the second transmission direction.

[0195] For example, in the case that the terminal is the relay terminal B, the first configuration information includes the second total QoS parameter used by the relay terminal C to the remote terminal in the second transmission direction, the relay terminal B can further split the second total QoS parameter to determine the QoS parameter used by the fourth target object between the relay terminal C and the relay terminal B in the second transmission direction and the remaining QoS parameter used by the fourth target object between the relay terminal B and the remote terminal in the second transmission direction.

[0196] For example, in the case that the terminal is the relay terminal B, the first configuration information includes the second total QoS parameter used by the relay terminal C to the remote terminal in the second transmission direction, the relay terminal B can further split the second total QoS parameter to determine the QoS parameter used by the fourth target object between the relay terminal C and the relay terminal B in the second transmission direction and the remaining QoS parameter used by the fourth target object between the relay terminal B and the remote terminal in the second transmission direction.

[0197] For example, in the case that the terminal is the relay terminal B, the first configuration information includes the second total QoS parameter used by the relay terminal C to the remote terminal in the second transmission direction, the relay terminal B can further split the second total QoS parameter to determine the QoS parameter used by the fourth target object between the relay terminal C and the relay terminal B in the second transmission direction and the remaining QoS parameter used by the fourth target object between the relay terminal B and the remote terminal in the second transmission direction.

[0198] For example, in the case that the terminal is the relay terminal B, the first configuration information includes the second total QoS parameter used by the relay terminal C to the remote terminal in the second transmission direction, the relay terminal B can further split the second total QoS parameter to determine the QoS parameter used by the fourth target object between the relay terminal C and the relay terminal B in the second transmission direction and the remaining QoS parameter used by the fourth target object between the relay terminal B and the remote terminal in the second transmission direction.

[0199] For example, in the embodiments of the present disclosure, when the terminal is a remote terminal, the terminal can further report first assistance information to the network device, and the first assistance information includes at least one of the following:

[0200] a QoS profile corresponding to all or part of an end-to-end QoS flow between the remote terminal and the network device;

[0201] a direct communication interface channel quality between the remote terminal and a first relay terminal, the first relay terminal being a relay terminal connected to the remote terminal through a direct communication interface;

[0202] a direct communication interface channel busy ratio between the remote terminal and the first relay terminal;

[0203] transmission path identification information used by the remote terminal to access the network device;

[0204] a hop count used by the remote terminal to access the network device;

[0205] all relay terminal identification information on a multi-hop relay link used by the remote terminal to access the network device.

[0206] For example, in the embodiments of the present disclosure, when the terminal is any relay terminal in a multi-hop relay link, the terminal can further report second assistance information to the network device, and the second assistance information includes at least one of the following:

[0207] a direct communication interface channel quality between the terminal and a first terminal, the first terminal being a last hop relay terminal of the terminal in a first transmission direction or a remote terminal;

[0208] an interface channel quality between the terminal and a first node, the first node being a last hop relay terminal of the terminal in a second transmission direction or a network device.

[0209] For example, in the embodiments of the present disclosure, the first assistance information or the second assistance information is carried by any of the following:

[0210] terminal assistance information;

[0211] direct communication interface terminal information;

[0212] a newly introduced other radio resource control (RRC) message;

[0213] a physical layer message of a Uu interface.

[0214] In this way, the remote terminal reports its first assistance information to the network device, and / or any relay terminal reports its second assistance information to the network device, so that the network device can perform multi-hop link QoS parameter segmentation based on the received assistance information to determine the QoS parameter used by each hop direct communication interface, thereby guaranteeing the end-to-end QoS of services in a multi-hop relay scenario.

[0215] To facilitate understanding of the service quality QoS parameter configuration method provided by the embodiments of the present disclosure, the service quality QoS parameter configuration method provided by the embodiments of the present disclosure will be described in detail below through the following two specific embodiments.

[0216] Embodiment 1

[0217] In Embodiment 1, taking the case where only the network device performs QoS segmentation as an example, it is assumed that the first configuration information sent by the network device to the terminal includes the first QoS parameter corresponding to the first target object between the terminal and its next hop relay terminal in the first transmission direction.

[0240] For example, in the embodiments of the present disclosure, the second assistance information reported by the relay terminal B to the network device can include at least one of the following:

[0241] a direct communication interface channel quality between the relay terminal B and the relay terminal A, such as SL-RSRP or SL-RSRP, etc.;

[0246] For example, in the embodiments of the present disclosure, the second assistance information reported by the relay terminal can be carried by any of the following:

[0247] terminal assistance information (UEAssistanceInformation);

[0248] direct communication interface terminal information (SidelinkUEInformation);

[0249] other RRC messages newly introduced;

[0250] a physical layer message of the Uu interface, such as CQI or CSI carried by PUCCH, etc.

[0251] It should be noted that in the embodiments of the present disclosure, S301, S302a, S302b and S302c are optional operations, and there is no sequence between S301, S302a, S302b and S302c, and the specific settings can be made according to actual needs.

[0252] S303, the network device performs multi-hop link QoS parameter segmentation.

[0253] In the embodiments of the present disclosure, the network device can segment the multi-hop link QoS parameter, determine the first QoS parameter corresponding to the first target object between the remote terminal and the relay terminal A, the first QoS parameter corresponding to the first target object between the relay terminal A and the relay terminal B, the first QoS parameter corresponding to the first target object between the relay terminal B and the relay terminal C, and the first QoS parameter corresponding to the first target object between the Uu interface of the relay terminal C and the network device.

[0254] For example, in the embodiments of the present disclosure, the first target object can include at least one of the following:

[0259] For example, in the embodiments of the present disclosure, the QoS parameter includes at least one of the following:

[0260] a packet delay budget PDB;

[0261] a packet error rate PER;

[0262] a packet data unit set delay budget PSDB;

[0263] a packet data unit set error rate PSER.

[0264] After the network device segments the multi-hop link QoS parameter, the network device can send the first configuration information corresponding to each of the remote terminal, the relay terminal A, the relay terminal B and the relay terminal C, that is, perform the following S304-S307.

[0265] S304, the network device sends the first configuration information corresponding to the remote terminal to the remote terminal.

[0266] The first configuration information corresponding to the remote terminal includes the first QoS parameter corresponding to the first target object between the remote terminal and the relay terminal A, so that the remote terminal uses the first QoS parameter to perform data transmission in the first transmission direction between the remote terminal and the relay terminal A.

[0267] S305, the network device sends the first configuration information corresponding to the relay terminal A to the relay terminal A.

[0268] The first configuration information corresponding to the relay terminal A includes the first QoS parameter corresponding to the first target object between the relay terminal A and the relay terminal B, so that the relay terminal A performs data transmission in the first transmission direction between the relay terminal A and the relay terminal B by using the first QoS parameter.

[0270] The first configuration information corresponding to the relay terminal B includes the first QoS parameter corresponding to the first target object between the relay terminal B and the relay terminal C, so that the relay terminal B performs data transmission in the first transmission direction between the relay terminal B and the relay terminal C by using the first QoS parameter.

[0271] S307, the network device sends the first configuration information corresponding to the relay terminal C to the relay terminal C.

[0272] The first configuration information corresponding to the relay terminal C includes the first QoS parameter corresponding to the first target object between the relay terminal C and the network device, so that the relay terminal C performs data transmission in the first transmission direction between the relay terminal C and the network device by using the first QoS parameter.

[0273] It should be noted that in the embodiments of the present disclosure, S304, S305, S306 and S307 have no sequence, and can be set according to actual needs.

[0274] It can be seen that in the embodiments of the present disclosure, the remote terminal and each relay terminal can report the respective auxiliary information to the network device, and correspondingly, the network device can perform multi-hop link QoS parameter segmentation based on the obtained auxiliary information, respectively determine the first QoS parameter corresponding to the first target object between the remote terminal and the relay terminal A, the first QoS parameter corresponding to the first target object between the relay terminal A and the relay terminal B, the first QoS parameter corresponding to the first target object between the relay terminal B and the relay terminal C, and the first QoS parameter corresponding to the first target object between the relay terminal C and the network device, and transmit the respective first QoS parameter of the remote terminal and each relay terminal through the first configuration information, so that the QoS parameter used by each hop direct communication interface can be determined, thereby guaranteeing the end-to-end QoS of the service in the multi-hop relay scenario.

[0275] Embodiment 2

[0276] In Embodiment 2, taking the network device and the relay terminal both performing QoS segmentation as an example, it is assumed that the first configuration information sent by the network device to the remote terminal includes a first total QoS parameter used by the third target object when transmitting between the remote terminal and the target relay terminal in a first transmission direction. The first transmission direction is an uplink transmission direction or a transmission direction from the remote terminal to the network device.

[0287] Terminal assistance information (UE Assistance Information);

[0288] Direct communication interface terminal information (Sidelink UE Information);

[0289] Other newly introduced radio resource control (RRC) messages;

[0290] CQI or CSI carried by a physical layer message of a Uu interface, such as a PUCCH.

[0291] For example, in the embodiments of the present disclosure, the relay terminal can also report its second assistance information to the network device.

[0292] For example, the relay terminal reporting the second assistance information to the network device can include:

[0293] S402a, the relay terminal A reports its second assistance information to the network device.

[0294] S402b, the relay terminal B reports its second assistance information to the network device.

[0295] S402c, the relay terminal C reports its second assistance information to the network device.

[0296] For example, in the embodiments of the present disclosure, the second assistance information reported by the relay terminal A to the network device can include at least one of the following:

[0297] The direct communication interface channel quality between the relay terminal A and the remote terminal, such as SL-RSRP or SL-RSRP, etc.

[0298] The interface channel quality between the relay terminal A and the relay terminal B, such as SL-RSRP or SL-RSRP, etc.

[0299] For example, in the embodiments of the present disclosure, the second assistance information reported by the relay terminal B to the network device can include at least one of the following:

[0300] The direct communication interface channel quality between the relay terminal B and the relay terminal A, such as SL-RSRP or SL-RSRP, etc.

[0301] The interface channel quality between the relay terminal B and the relay terminal C, such as SL-RSRP or SL-RSRP, etc.

[0302] For example, in the embodiments of the present disclosure, the second assistance information reported by the relay terminal C to the network device can include at least one of the following:

[0303] A channel quality of a direct communication interface between the relay terminal C and the relay terminal B, for example, SL-RSRP or SL-RSRP, and the like;

[0304] A channel quality of a Uu interface between the relay terminal C and the network device, for example, SL-RSRP or SL-RSRP, and the like.

[0305] For example, in the embodiment of the present disclosure, the second assistance information reported by the relay terminal can be carried by any of the following:

[0306] Terminal assistance information (UEAssistanceInformation);

[0307] Direct communication interface terminal information (SidelinkUEInformation);

[0308] Other RRC messages newly introduced;

[0309] A physical layer message of the Uu interface, for example, CQI or CSI carried by PUCCH, and the like.

[0310] It should be noted that in the embodiment of the present disclosure, S401, S402a, S402b and S402c are optional operations, and there is no sequence between S401, S402a, S402b and S402c, which can be set according to actual needs.

[0311] S403, the network device performs multi-hop link QoS parameter segmentation.

[0312] In the embodiment of the present disclosure, the network device can divide the QoS parameter between the remote terminal and the network device on the Uu interface and other interfaces of the multi-hop link, determine a first total QoS parameter used by the third target object when transmitted between the remote terminal and the relay terminal C, and a QoS parameter used by the third target object when transmitted on the Uu interface between the relay terminal C and the network device.

[0313] For example, in the embodiment of the present disclosure, the third target object can include at least one of the following:

[0314] An end-to-end bearer between the remote terminal and the network device;

[0315] An end-to-end QoS flow identifier between the remote terminal and the network device;

[0316] An end-to-end QoS profile between the remote terminal and the network device;

[0317] An end-to-end QoS profile identifier between the remote terminal and the network device.

[0318] For example, in the embodiments of the present disclosure, the QoS parameter includes at least one of the following:

[0319] a packet delay budget;

[0320] a packet error rate;

[0321] a packet data unit set delay budget;

[0322] a packet data unit set error rate.

[0323] After the network device determines the first total QoS parameter used by the third target object when transmitted between the remote terminal and the relay terminal C by splitting the QoS parameter between the remote terminal and the network device, the network device can perform the following S404:

[0324] S404, the network device sends first configuration information to the remote terminal.

[0325] The first configuration information includes the first total QoS parameter used by the third target object when transmitted between the remote terminal and the relay terminal C.

[0326] S405, the remote terminal sends a first notification message to the relay terminal A.

[0327] The first notification message carries the first total QoS parameter used by the third target object when transmitted between the remote terminal and the relay terminal C.

[0328] S406, the relay terminal A performs first total QoS parameter splitting.

[0329] For example, after the relay terminal A receives the first total QoS parameter used by the third target object when transmitted between the remote terminal and the relay terminal C, the relay terminal A can split the first total QoS parameter to determine the QoS parameter used by the third target object when transmitted between the remote terminal and the relay terminal A, and the remaining total QoS parameter used by the third target object when transmitted between the relay terminal A and the relay terminal C.

[0330] For example, in the embodiment of the present disclosure, after the network device divides the QoS parameter between the remote terminal and the network device, determines the first total QoS parameter used by the third target object when transmitting between the remote terminal and the relay terminal C, and further sends the first configuration information to the relay terminal A, the first configuration information includes the first total QoS parameter used by the third target object when transmitting between the remote terminal and the relay terminal C, that is, the network device does not need to perform S404 and S406; after receiving the first configuration information, the relay terminal A performs S406 to divide the first total QoS parameter, which can be set according to actual needs. In this embodiment of the present disclosure, the network device sends the first total QoS parameter used by the third target object when transmitting between the remote terminal and the relay terminal C to the remote terminal, and the remote terminal sends the first total QoS parameter to the relay terminal A, but this does not mean that the embodiment of the present disclosure is limited to this.

[0331] S407, the relay terminal A sends a second notification message 1 to the remote terminal.

[0332] The second notification message 1 carries the QoS parameter used by the third target object when transmitting between the remote terminal and the relay terminal A, so that the remote terminal uses the QoS parameter to perform data transmission in the first transmission direction between the remote terminal and the relay terminal A.

[0336] S409, the relay terminal B performs remaining total QoS parameter division.

[0337] For example, after the relay terminal B receives the remaining total QoS parameter used by the third target object when transmitting between the relay terminal A and the relay terminal C, the relay terminal B can divide the remaining total QoS parameter to determine the QoS parameter used by the third target object when transmitting between the relay terminal A and the relay terminal B, and the QoS parameter used by the third target object when transmitting between the relay terminal B and the relay terminal C.

[0342] It should be noted that, in the embodiments of the present disclosure, there is no sequence between S410 and S411. In this embodiment, the execution of S410 is taken as an example, but it does not mean that the embodiments of the present disclosure are limited to this.

The relay terminal A segments the first total QoS parameters, determines the QoS parameters used when the remote terminal and the relay terminal A are transmitted, and the remaining total QoS parameters used when the relay terminal A and the relay terminal C are transmitted; and sends the QoS parameters used when the remote terminal and the relay terminal A are transmitted to the remote terminal, so that the remote terminal performs data transmission in the first transmission direction between the remote terminal and the relay terminal A by using the QoS parameters; sends the remaining total QoS parameters used when the relay terminal A and the relay terminal C are transmitted to the relay terminal B; the relay terminal B segments the remaining total QoS parameters, determines the QoS parameters used when the relay terminal A and the relay terminal B are transmitted, and the QoS parameters used when the relay terminal B and the relay terminal C are transmitted; and sends the QoS parameters used when the relay terminal A and the relay terminal B are transmitted to the relay terminal A, so that the relay terminal A performs data transmission in the first transmission direction between the relay terminal A and the relay terminal B by using the QoS parameters; and sends the QoS parameters used when the relay terminal B and the relay terminal C are transmitted to the relay terminal B, so that the relay terminal B performs data transmission in the first transmission direction between the relay terminal B and the relay terminal C by using the QoS parameters. In this way, the QoS parameters used by each hop direct communication interface can be determined, so as to guarantee the end-to-end QoS of the service in the multi-hop relay scenario.
