[0025] The embodiments of the present application will be described below in conjunction with the accompanying drawings in the embodiments of the present application.

[0026] The term "and / or" in the present application is merely used to describe the association relationship of the associated objects, and indicates that there can be three relationships, for example, A and / or B can represent the three cases of A alone, A and B together, and B alone. In addition, the character " / " in the present application indicates that the front and rear associated objects are in an "or" relationship.

[0027] "Multiple" appearing in the embodiments of the present application means two or more. The first, second, etc. appearing in the embodiments of the present application are only used for description and distinction of the description objects, and do not have order, nor represent a special limitation on the number of devices in the embodiments of the present application, and cannot constitute any limitation on the embodiments of the present application. The "connection" appearing in the embodiments of the present application means direct connection or indirect connection and various connection modes to achieve communication between devices, and the embodiments of the present application do not make any limitation on this.

[0028] The technical solutions of the embodiments of the present application can be applied to an example communication system as shown in Figure 1 The example communication system includes a terminal 110 and a network device 120, the terminal 110 is in communication connection with the network device 120, the network device 120 can be a base station 1 and a base station 2, and the terminal 110 is connected with the base station 1 and the base station 2 at the same time, that is, the terminal 110 is in dual connection.

[0029] The example communication system can be, for example, a Global System of Mobile communication (GSM) system, a Code Division Multiple Access (CDMA) system, a Wideband Code Division Multiple Access (WCDMA) system, a General Packet Radio Service (GPRS), a Long Term Evolution (LTE) system, an Advanced long term evolution (LTE-A) system, a New Radio (NR) system, an evolved system of the NR system, an LTE-based access to unlicensed spectrum (LTE-U), an NR-based access to unlicensed spectrum (NR-U), a Universal Mobile Telecommunication System (UMTS), a next generation communication system, or other communication systems.

[0030] Generally, a conventional communication system supports a limited number of connections and is easy to implement. However, with the development of communication technology, a mobile communication system will not only support conventional communications, but also support, for example, Device to Device (D2D) communication, Machine to Machine (M2M) communication, Machine Type Communication (MTC), and Vehicle to Vehicle (V2V) communication, and the like. Embodiments of the present application can also be applied to these communication systems. Optionally, the communication system in embodiments of the present application can be applied to a Carrier Aggregation (CA) scenario, a Dual Connectivity (DC) scenario, and a Standalone (SA) network deployment scenario.

[0031] The terminal 110 in the embodiments of the present application can refer to a user equipment, an access terminal, a user unit, a user station, a mobile station, a mobile station, a remote station, a remote terminal, a mobile device, a user terminal, a terminal, a wireless communication device, a user agent or a user apparatus. The terminal can also be a cellular phone, a cordless phone, a session initiation protocol (SIP) phone, a wireless local loop (WLL) station, a personal digital assistant (PDA), a handheld device with wireless communication function, a computing device or other processing device connected to a wireless modem, a relay device, a vehicle-mounted device, a wearable device, a terminal in a future 5G network or a terminal in a future evolved public land mobile network (PLMN), etc., and the embodiments of the present application are not limited thereto.

[0032] The network device 120 in the embodiments of the present application can be a device for communicating with the terminal. The network device can be an evolved NodeB (eNB or eNodeB) in an LTE system, and can also be a wireless controller in a cloud radio access network (CRAN) scenario, or the network device can be a relay device, an access point, a vehicle-mounted device, a wearable device, a network device in a future 5G network or a network device in a future evolved PLMN network, one or a group (including multiple antenna panels) of antenna panels of a base station in a 5G system, or can also be a network node constituting a gNB or a transmission point, such as a baseband unit (BBU), or a distributed unit (DU), etc., and the embodiments of the present application are not limited thereto.

[0033] In some deployments, a gNB can include a centralized unit (CU) and a DU. The gNB can also include an active antenna unit (AAU). The CU implements part of the functionality of the gNB, and the DU implements part of the functionality of the gNB. For example, the CU is responsible for processing non-real-time protocols and services, implements the radio resource control (RRC), and the functions of the packet data convergence protocol (PDCP) layer. The DU is responsible for processing the physical layer protocol and real-time services, and implements the functions of the radio link control (RLC) layer, the media access control (MAC) layer, and the physical (PHY) layer.

[0034] Referring to Figure 2a , Figure 2a An IAB (Integrated Access Backhaul) technology architecture is provided, which can be understood as a relay technology. The feature of the IAB architecture is that the transmission mechanism of NR Uu (Uu specifically refers to the interface when the base station and the terminal are directly connected) is used between the IAB node and the base station, and between the IAB node and the terminal.

[0035] In the IAB discussion, the uplink resources of the terminal are allocated by the IAB node, and the uplink resources of the IAB node are allocated by the base station. Naturally, they both need to send a BSR to the IAB node and the base station to request resources, but such a relay technology will cause transmission delay. For example, a data packet first reaches the terminal, the terminal sends a BSR to the IAB node to request resources, the IAB node allocates resources after receiving the BSR, the terminal sends a specific data packet, and then the IAB node sends a BSR to the base station to request resource allocation after receiving the specific data packet, resulting in additional transmission delay.

[0036] In order to reduce the additional transmission time, a pre-emptive BSR mechanism is introduced. When the IAB node receives a BSR from the terminal, it triggers the sending of a BSR to the base station, that is, it tells the base station in advance that although the data has not been received, it is estimated that how much data needs to be sent, so that the base station can schedule resources in advance.

[0037] Although the pre-emptive BSR mechanism is introduced in the IAB architecture, it can be applied to all relay forwarding scenarios. As long as the sending resources of the relay are allocated by the receiving end, the relay can trigger the request for resources to the receiving end in advance before receiving the specific data packet of the sending end, thereby reducing the transmission delay of the data after the introduction of the relay; however, likeFigure 2b In the relay dual connectivity network architecture shown, for example, a terminal communicates with a network through a relay, the relay connects with two base stations at the same time due to insufficient rate, and adopts a split-bearer form to transmit data to the network. In this case, the pre-emptive BSR mechanism cannot be implemented.

[0038] In the present application, the BSR can carry data size information of existing data, and the pre-emptive BSR can carry data size information of data expected to be received.

[0039] Referring to Figure 3 , Figure 3 A BSR triggering method of a relay is provided, which is implemented under the architecture shown in Figure 2b , and is executed by the relay shown in Figure 2b , and includes the following steps shown in Figure 3 .

[0040] In step S300, when the relay determines that a certain service bearer is a split bearer, whether a preset condition is met is determined according to data size of the certain service.

[0041] The definition of the split bearer can be referred to the definition above, and will not be repeated here.

[0042] The certain service can be a service of a single UE, or a service of multiple UEs.

[0043] In step S301, the BSR triggering strategy of the protocol stack under the dual connectivity state is determined according to whether the preset condition is met.

[0044] The technical solution provided in the present application determines whether a preset condition is met according to data size of a certain service when a certain service bearer is a split bearer, determines the BSR triggering strategy of the protocol stack under the dual connectivity state, and then implements the pre-emptive BSR working mechanism in the relay, thereby improving network performance.

[0045] In an alternative solution, the above method can specifically include at least one of the following:

[0046] If the predicted data size of the certain service from the child node is greater than or equal to a first threshold value, the relay determines that the preset condition is met, and the relay triggers the pre-emptive BSR at the primary first protocol layer and / or triggers the pre-emptive BSR at the secondary first protocol layer;

[0047] If the data size of the certain service is less than the first threshold value, it is determined that the preset condition is not met, and the relay only triggers the pre-emptive BSR at the primary first protocol layer;

[0048] The main first protocol layer is a first protocol layer associated with a main base station; and the auxiliary first protocol layer is a first protocol layer associated with an auxiliary base station.

[0049] The first threshold value can be a preset threshold value.

[0050] The main first protocol layer can be a first protocol layer associated with the main base station within the relay, and the auxiliary first protocol layer can be a first protocol layer associated with the auxiliary base station within the relay. The first protocol layer can be a MAC layer.

[0051] In an optional solution, the method can include at least one of the following:

[0052] The relay obtains a sum of an existing data amount of a certain service and a predicted data amount from the child node;

[0053] If the sum is greater than or equal to a second threshold value, the relay determines that a preset condition is met, and the second protocol layer of the relay indicates the data amount of the second protocol layer to both the main third protocol layer and the auxiliary third protocol layer;

[0054] If the sum is greater than or equal to a second threshold value, the relay determines that a preset condition is met, and the second protocol layer of the relay indicates the data amount of the second protocol layer to both the main third protocol layer and the auxiliary third protocol layer;

[0055] If the sum is less than the second threshold value, the relay determines that the preset condition is not met, and the second protocol layer of the relay indicates the data amount of the second protocol layer to the main third protocol layer;

[0056] If the sum is less than the second threshold value, the relay determines that the preset condition is not met, and the second protocol layer of the relay indicates the data amount of the second protocol layer to the main third protocol layer;

[0057] If the main third protocol layer of the relay receives the data amount indication from the second protocol layer, the main first protocol layer of the relay triggers a BSR;

[0058] If the auxiliary third protocol layer of the relay receives the data amount indication from the second protocol layer, the auxiliary first protocol layer of the relay triggers a BSR;

[0059] If the main protocol stack of the relay receives the data amount indication from the second protocol layer, the main first protocol layer of the relay triggers a BSR;

[0060] If the auxiliary protocol stack of the relay receives the data amount indication from the second protocol layer, the auxiliary first protocol layer of the relay triggers a BSR; in an optional solution, the method can include at least one of the following:

[0061] The relay obtains a sum of an existing data amount of a certain service and a predicted data amount from the child node;

[0062] If the sum is greater than or equal to the second threshold value, the relay determines that the preset condition is met, and the second protocol layer of the relay sends indication information to the secondary third protocol layer;

[0063] If the sum is greater than or equal to the second threshold value, the relay determines that the preset condition is met, and the second protocol layer of the relay sends indication information to the secondary third protocol layer;

[0064] If the secondary third protocol layer of the relay receives the data volume indication from the second protocol layer, the secondary first protocol layer of the relay triggers the pre-emptive BSR;

[0065] If the secondary third protocol layer of the relay receives the data volume indication from the second protocol layer, the secondary first protocol layer of the relay triggers the pre-emptive BSR;

[0066] The primary third protocol layer is a third protocol layer associated with a primary base station, and the primary protocol stack is a protocol stack associated with the primary base station; the secondary protocol stack is a protocol stack associated with a secondary base station, and the secondary third protocol layer is a third protocol layer associated with the secondary base station.

[0067] The third protocol layer is an RLC layer, and the second protocol layer is a PDCP layer or a BAP layer. It should be noted that, although the primary third protocol layer and the secondary third protocol layer have the same name, they are actually two protocol layers in the relay because they are associated with different devices.

[0068] In an optional solution,

[0069] The protocol stack is a preset protocol stack.

[0070] Or the protocol stack is a protocol stack determined by the network device.

[0071] Embodiment one

[0072] Embodiment one of the present application provides a BSR triggering method of a relay, which is executed under a network architecture as shown in Figure 2b The relay includes a primary first protocol layer, which can be a MAC layer associated with a primary base station in the relay, i.e., a primary MAC layer, and the relay also includes a secondary first protocol layer, which can be a MAC layer associated with a secondary base station in the relay, i.e., a secondary MAC layer. The method includes the following steps as shown in Figure 4

[0073] Step S400: The relay predicts whether the data volume of a certain service from a child node is greater than or equal to a first threshold value:

[0074] ​The implementation method of the relay predicting the data amount of a certain service from the child node can specifically predict the data amount of a certain service based on the content of the received BSR from the child node; of course, in actual application, the data amount of a certain service can also be predicted by the scheduling resource size allocated to the child node.

[0075] Step S401, if the predicted data amount of a certain service from the child node is greater than or equal to the first threshold, the relay triggers a pre-emptive BSR at the primary first protocol layer and / or triggers a pre-emptive BSR at the secondary first protocol layer.

[0076] Step S402, if the predicted data amount of a certain service from the child node is less than the first threshold, only a pre-emptive BSR is triggered at the primary first protocol layer.

[0077] The certain service in the embodiments of the present application can be a certain logical channel, and of course in actual application, it can also be a certain logical channel group.

[0078] In the first embodiment of the present application, whether the data amount from the child node is greater than or equal to the first threshold is only a necessary condition for triggering a pre-emptive BSR, but not a sufficient condition, and whether the pre-emptive BSR is finally triggered depends on other conditions, for example, when the BSR from the child node is received, when the transmission resource is allocated to the child node.

[0079] The technical solution of the first embodiment is that when the relay predicts that the data amount to be received exceeds the threshold, the pre-emptive BSR is triggered to the primary and secondary base stations under the condition that other triggering conditions of the pre-emptive BSR are met, otherwise the pre-emptive BSR is only triggered to the primary base station. The first embodiment of the present application designs the working mechanism of the pre-emptive BSR when the relay communicates with the network through dual connectivity and is a split bearer, thereby improving the network performance.

[0080] Embodiment Two

[0081] The second embodiment of the present application provides a BSR triggering method of a relay, which is as follows: Figure 2bThe method is executed under the network architecture shown, is executed by a relay, and the relay includes a primary second protocol layer, a primary third protocol layer, the primary second protocol layer can be a PDCP layer or a BAP layer in the relay associated with a primary base station, that is, a primary PDCP layer or a BAP layer, and the primary third protocol layer can be an RLC layer in the relay associated with the primary base station. The relay includes a secondary second protocol layer, a secondary third protocol layer, the secondary second protocol layer can be a PDCP layer or a BAP layer in the relay associated with a secondary base station, that is, a secondary PDCP layer or a BAP layer, and the secondary third protocol layer can be an RLC layer in the relay associated with the secondary base station. The method includes the following steps as shown in Figure 5 The method includes the following steps as shown in

[0082] In step S500, the relay determines whether the sum of the data amount of the data already present and the predicted data amount from the child node is greater than or equal to a second threshold value:

[0083] The implementation method of the predicted data amount from the child node of the relay can refer to the specific description of step S400 described above, and will not be described here.

[0084] The data amount of the data already present can be the sum of the data amount on the second protocol layer and the data amount on the third protocol layer (including the data waiting for initial transmission on the primary third protocol layer and the data waiting for initial transmission on the secondary third protocol layer).

[0085] The second threshold value can be the same as the first threshold value in Embodiment 1, or can be greater than or less than the first threshold value.

[0086] In step S501, if it is determined that the sum is greater than or equal to the second threshold value, the second protocol layer of the relay indicates the data amount of the second protocol layer to the primary third protocol layer (or the primary protocol stack) and the secondary third protocol layer (or the secondary protocol stack), and the primary first protocol layer and the secondary first protocol layer of the relay both trigger a BSR.

[0087] In step S502, if it is determined that the sum is less than the second threshold value, the second protocol layer of the relay only indicates the data amount of the second protocol layer to the primary third protocol layer (or the primary protocol stack), and the secondary first protocol layer of the relay triggers a BSR. The certain service in the embodiments of the application can be a certain logical channel, and of course in actual application, it can also be a certain logical channel group.

[0088] The technical solution of the second embodiment of the present application is that when the sum of the data amount of the data already having data of a certain service and the predicted data amount from the child node exceeds the second threshold value, the second protocol layer indicates the data to both the main third protocol layer and the auxiliary third protocol layer, so that the main first protocol layer and the auxiliary first protocol layer of the relay trigger the BSR, otherwise, the second protocol layer indicates the data only to the main third protocol layer, so that the BSR is triggered only at the main first protocol layer. The second embodiment of the present application designs the working mechanism of the BSR when the relay communicates through the dual connectivity and the network and the split bearer is used, thereby improving the network performance.

[0089] Embodiment three

[0090] The third embodiment of the present application provides a BSR triggering method of a relay, which is executed under the network architecture as shown in Figure 2b The relay comprises a main second protocol layer, a main third protocol layer, the main second protocol layer can be a PDCP layer or a BAP layer associated with the main base station in the relay, i.e. a main PDCP layer or a BAP layer, and the main third protocol layer can be an RLC layer associated with the main base station in the relay. The relay comprises an auxiliary second protocol layer, an auxiliary third protocol layer, the auxiliary second protocol layer can be a PDCP layer or a BAP layer associated with the auxiliary base station in the relay, i.e. an auxiliary PDCP layer or a BAP layer, and the auxiliary third protocol layer can be an RLC layer associated with the auxiliary base station in the relay. The method comprises the following steps as shown in Figure 6

[0091] Step S600, the relay determines whether the sum of the data amount of the data already having data of a certain service and the predicted data amount from the child node is greater than or equal to the second threshold value:

[0092] The implementation method of the predicted data amount from the child node of the relay can refer to the specific description of step S400 above, which will not be repeated here.

[0093] The data amount of the data already having data can be the sum of the data amount on the second protocol layer and the data amount on the third protocol layer (including the data waiting for initial transmission on the main third protocol layer and the data waiting for initial transmission on the auxiliary third protocol layer).

[0094] The second threshold value can be the same as the first threshold value in the first embodiment, or can be greater than or less than the first threshold value.

[0095] Step S601, if it is determined that the sum is greater than or equal to the second threshold value, the second protocol layer of the relay sends indication information to the auxiliary third protocol layer (or the auxiliary protocol stack), and the auxiliary first protocol layer of the relay triggers the pre-emptive BSR.

[0096] The certain service in the embodiment of the present application can be a certain logical channel, and of course in actual application, it can also be a certain logical channel group.​

[0097] The technical solution of the third embodiment is that when the sum of the relayed data amount of a certain service and the predicted data amount from the child node exceeds the second threshold value, the indication information is sent to the secondary third protocol layer, so that the relayed primary first protocol layer triggers the pre-emptive BSR, otherwise only the relayed main first protocol layer triggers the pre-emptive BSR. The working mechanism of the pre-emptive BSR is designed when the relay is connected through the dual connection and the network communication and the split bearer, and thus the network performance is improved.
