Description

A communication method and related apparatus

[0001] This application claims priority to Chinese Patent Application No. 202510208482.8, filed on February 24, 2025, entitled "A Communication Method and Related Device", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of communications, and more particularly to a communication method and related apparatus. Background Technology

[0003] Currently, an increasing number of scenarios require the transmission of uplink data. Uplink data refers to data sent from user equipment (UE) to network devices (such as base stations) or servers. For example, data sent during email transmission, file uploads, or form submissions all fall under the category of uplink data. This data is transmitted over the network from the user equipment's network interface to the target server or network device.

[0004] When uplink data needs to be transmitted, the UE sends a scheduling request (SR) to the base station on the physical uplink control channel (PUCCH), thereby requesting uplink authorization from the base station. Upon receiving the SR, the base station responds by instructing the UE with scheduling information via the PDCCH. The base station schedules the UE according to a small, fixed data volume. When the amount of data the UE needs to transmit is large, this scheduling method has low data transmission efficiency.

[0005] Therefore, improving data transmission efficiency is a technical problem that urgently needs to be solved. Summary of the Invention

[0006] This application provides a communication method and related apparatus for improving data transmission efficiency.

[0007] This application provides a communication method applied to, or executed by, a first device. The first device may be a communication device (such as a terminal device or network device), or it may be a component of the communication device (e.g., a circuit or chip responsible for communication functions, such as a modem / demodulator chip, also known as a baseband chip, or a system-on-a-chip (SoC) chip containing a modem core, or a system-in-package (SIP) chip, etc.). Alternatively, the first device may be a logic module or software capable of implementing all or part of the functions of the communication device. In this method, the first device sends a first scheduling request (SR), which indicates a resource to be scheduled for data transmission. The first SR indicates that the data has a first characteristic including: the data volume is greater than a first threshold or the data transmission delay requirement is lower than a second threshold. The first device receives first information based on the first SR, which indicates a first resource. The first device then transmits first data on the first resource according to the first information.

[0008] In the first aspect, the first device needs to send data; for example, the first device can be a terminal device, and the second device can be a base station. The first device needs to send uplink data to the second device. To send the data, the first device sends a first SR (Redirect Resource Scheduler), which indicates the resources to be scheduled for data transmission. In this application, the first characteristic of the data indicated by the first SR includes: the data volume is greater than a first threshold or the data transmission latency requirement is lower than a second threshold. Therefore, the device receiving the first SR can determine that the data volume to be transmitted by the first device is large, and the data transmission latency is high. The first device receives first information based on the first SR, which indicates a first resource. The first device then sends the first data on the first resource according to the first information. In this application, the first SR can notify the device receiving the first SR that the data volume to be transmitted is large or the data transmission latency is high. The device receiving the first SR can accordingly adjust the resources scheduled for data transmission allocated to the first device to be larger, or adjust the priority of resource scheduling for the first device to schedule resources in a timely manner. Thus, the resources available for data transmission by the first device are sufficient, avoiding data transmission delays due to insufficient resources and improving data transmission efficiency. Furthermore, since there is no need to send a BSR to notify the base station of data volume and / or latency requirements, the time required for the first device to exchange data volume and latency requirements with the base station is shortened, thereby improving data transmission efficiency.

[0009] In one possible implementation of the first aspect, the first SR includes first indication information and second indication information, the first indication information being used to indicate that data transmission is required, and the second indication information being used to indicate that the data volume is greater than the first threshold or that the latency requirement for the data transmission is lower than the second threshold.

[0010] Based on the above implementation, the first SR can directly indicate that the data volume is greater than the first threshold and / or the data transmission latency requirement is lower than the second threshold. Therefore, the second device can directly determine from the first SR that the data volume to be transmitted is large and / or the data transmission latency requirement is high, thereby allocating more physical uplink shared channel (PUSCH) resources to the first device or increasing the priority of resource allocation to the first device, thus improving the data transmission efficiency of the first device. In the above example, the methods for determining the data volume characteristics and data transmission latency requirements of the interactive data are relatively simple, direct, and efficient.

[0011] In one possible implementation of the first aspect, the first device receives second information indicating that a second resource is used to carry a first type of SR, the first type of SR indicating a resource for scheduling data that satisfies the first characteristic; the first device transmits the first SR on the second resource.

[0012] Based on the above implementation, the first device can carry the first type of SR through dedicated resources, namely the second resource, that is, the SR that carries resources used to schedule data that meets the first characteristic. Thus, when the second device receives an SR sent through the second resource, it can determine that data that meets the first characteristic needs to be transmitted, thereby allocating more PUSCH resources to the first device or increasing the priority of allocating resources to the first device, thereby improving the data transmission efficiency of the first device.

[0013] In one possible implementation of the first aspect, the first device sends a first scheduling request configuration information (BSR), the first BSR including: first time information or a delay requirement for data transmission, the first time information indicating the expected time for data transmission; the first device receives third information obtained based on the first BSR, the third information indicating a third resource; and the first device sends second data on the third resource according to the third information.

[0014] Based on the above implementation, the first device can notify the second device of the expected time to send data through the first BSR, so that the second device can perform resource scheduling planning in advance and schedule resources for the first device to transmit data in a timely manner, thereby improving the efficiency of the first device in transmitting data; and / or the first device can notify the second device of the latency requirements for data transmission through the first BSR. When the latency requirements for data transmission are high, the second device can increase the priority of the first device's resource scheduling, thereby scheduling resources for the first device to transmit data in a timely manner, thereby improving the efficiency of the first device in transmitting data.

[0015] In one possible implementation of the first aspect, the first data is uplink data; the first device monitors second time information, which is the time information of the first data and the time information of the downlink data corresponding to the first data; the first device receives fourth information, which includes the first uplink data; the first device determines the characteristics of the first downlink data based on the second time information and the fourth information, the first downlink data being the downlink data corresponding to the first uplink data, and the characteristics of the first downlink data including: transmission time or data volume; and the characteristics of the first device transmitting the first downlink data.

[0016] Based on the above implementation, the first device can predict the characteristics of the downlink data, namely the transmission time and / or data volume of the downlink data. Thus, the first device can send the characteristics of the downlink data to the second device, so that the second device can reasonably arrange the scheduling time according to the characteristics of the downlink data, reserve resources in advance, and schedule sufficient resources for the first device in a timely manner, so as to avoid the first device from experiencing data transmission delays due to insufficient resources and improve the data transmission efficiency of the first device.

[0017] In one possible implementation of the first aspect, the fourth information further includes: the service characteristics of the first service or the type of the first uplink data, wherein the first service is the service corresponding to the first uplink data.

[0018] Based on the above implementation, the characteristics of the first downlink data can be determined according to the service characteristics of the first service or the type of the first uplink data. The service characteristics of the first service or the type of the first uplink data can help determine the transmission pattern, data volume, and data transmission latency requirements of the first downlink data, thereby enabling better prediction of the transmission time and data volume of the first downlink data.

For example, in an open access network (open RAN, O-RAN, or ORAN) system, CU can also be called O-CU (open CU), DU can also be called O-DU, CU-CP can also be called O-CU-CP, CU-UP can also be called O-CU-UP, and RU can also be called O-RU. For ease of description, this application uses CU, CU-CP, CU-UP, DU, and RU as examples. Any of the units among CU (or CU-CP, CU-UP), DU, and RU in this application can be implemented through software modules, hardware modules, or a combination of software modules and hardware modules.

[0083] Please refer to Figure 1, which shows the NR protocol stack and network element modules on the base station side. For the correspondence between network elements in the ORAN system and their implementable protocol layer functions, please refer to Table 1 below:

[0084] Table 1

[0085] Network devices can be other devices that provide wireless communication functions for terminal devices. The embodiments of this application do not limit the specific technology or form of the network device. For ease of description, the embodiments of this application are not limited.

[0086] Network equipment may also include core network equipment, such as the Mobility Management Entity (MME), Home Subscriber Server (HSS), Serving Gateway (S-GW), Policy and Charging Rules Function (PCRF), and Public Data Network Gateway (PDN Gateway, P-GW) in 4th generation (4G) networks; and access and mobility management function (AMF), user plane function (UPF), or session management function (SMF) in 5G networks. Furthermore, this core network equipment may also include other core network equipment in 5G networks and next-generation networks of 5G networks.

[0087] Network equipment may also include core network equipment, which communicates with the UE via a base station. Core network equipment may include the following network elements:

[0088] Access and mobility management function (AMF): Primarily responsible for mobility management in mobile networks, such as user location updates, user network registration, and user handover.

[0089] Session Management Function (SMF): Primarily responsible for session management in mobile networks, such as session establishment, modification, and release. Specific functions include assigning IP addresses to users and selecting User Plane Functions (UPFs) to provide packet forwarding capabilities.

[0095] Optionally, the definitions and boundaries of gNB and CN in this application may differ from the existing division of gNB and CN in NR. For example, gNB may only be responsible for a part of the functions in the existing NR gNB, while other functions may be merged into a part of the network elements of CN or become independent network elements that communicate directly with the existing 5GC service bus.

[0096] In this application embodiment, the device for implementing the function of the network device can be the network device itself, or it can be a device capable of supporting the network device in implementing that function, such as a chip system, which can be installed in the network device. In the technical solutions provided in this application embodiment, the example of a network device being used to implement the function of the network device is used to describe the technical solutions provided in this application embodiment.

[0097] (3) Wireless Access Network Protocol Stack

[0098] Network devices and terminal devices have a specific protocol stack structure for mutual communication. For example, the user plane protocol stack structure may include at least one of the following: radio resource control (RRC) layer, service data adaptation protocol (SDAP) layer, packet data convergence protocol (PDCP) layer, radio link control (RLC) layer, media access link control (MAC) layer, and physical layer. The physical layer is the lowest layer (layer one), the MAC layer, RLC layer, PDCP layer, and SDAP layer belong to the second layer (layer two), and the RRC layer belongs to the third layer (layer three).

[0099] Please refer to Figure 2. For the NR user plane protocol stack, the SDAP and PDCP layers are located above the MAC and RLC layers (Figure 2), and downlink data transmission proceeds in the direction indicated by the arrows:

[0100] Downlink data first arrives at the base station's SDAP layer. After mapping by the SDAP layer, it is transmitted to the corresponding PDCP entity. After processing by the base station's PDCP layer, it is transmitted to the RLC and MAC layers. After further processing, it is sent out from the physical layer and transmitted to the UE via the air interface. Then, the various protocol layers on the UE side process the data packets sequentially in the reverse order of the base station's processing. On the base station and UE sides, the combined processing of data packets by each layer can be figuratively called a radio bearer. Each piece of data in the radio bearer needs to be processed by each layer, and each layer has a corresponding functional entity to perform its function, such as the PDCP entity in the PDCP layer. Each radio bearer configuration contains a PDCP entity, and the radio bearer configuration is associated with an RLC entity and corresponds to a logical channel.

[0101] In the current NR protocol stack, the PDCP, RLC, MAC, and PHY involved in processing a single service flow (QoS flow) are processed serially, with data packets processed sequentially according to their hierarchical relationship.

[0102] (4) The terms "system" and "network" in the embodiments of this application can be used interchangeably. "At least one" means one or more, and "more" means two or more. "And / or" describes the relationship between related objects, indicating that there can be three relationships. For example, A and / or B can mean: A exists alone, A and B exist simultaneously, or B exists alone, where A and B can be singular or plural. The character " / " generally indicates that the related objects before and after are in an "or" relationship. "At least one of the following" or similar expressions refer to any combination of these items, including any combination of single or plural items. For example, "at least one of A, B and C" includes A, B, C, AB, AC, BC or ABC. And, unless otherwise specified, the ordinal numbers such as "first" and "second" mentioned in the embodiments of this application are used to distinguish multiple objects and are not used to limit the order, sequence, priority or importance of multiple objects.

[0103] (5) In the embodiments of this application, "send" and "receive" indicate the direction of signal transmission. For example, "send information to XX" can be understood as the destination of the information being XX, which may include sending directly through the air interface or sending indirectly through the air interface by other units or modules. "Receive information from YY" can be understood as the source of the information being YY, which may include receiving directly from YY through the air interface or receiving indirectly from YY through the air interface by other units or modules. "Send" can also be understood as the "output" of the chip interface, and "receive" can also be understood as the "input" of the chip interface.

[0104] In other words, sending and receiving can occur between devices, such as between network devices and terminal devices, or within a device, such as between components, modules, chips, software modules, or hardware modules within the device via buses, wiring, or interfaces.

[0105] It is understandable that information may undergo necessary processing, such as encoding and modulation, between the source and destination, but the destination can understand the valid information from the source. Similar statements in this application can be interpreted in a similar way and will not be elaborated further.

[0106] (6) In the embodiments of this application, "instruction" may include direct instruction and indirect instruction, as well as explicit instruction and implicit instruction. The information indicated by a certain piece of information (as described below, the instruction information) is called the information to be instructed. In the specific implementation process, there are many ways to indicate the information to be instructed, such as, but not limited to, directly indicating the information to be instructed, such as the information to be instructed itself or its index. It can also indirectly indicate the information to be instructed by indicating other information, where there is an association between the other information and the information to be instructed; or it can only indicate a part of the information to be instructed, while the other parts of the information to be instructed are known or pre-agreed upon. For example, the instruction can be implemented by using a pre-agreed (e.g., protocol predefined) arrangement order of various information, thereby reducing the instruction overhead to a certain extent. This application does not limit the specific method of instruction. It is understood that for the sender of the instruction information, the instruction information can be used to indicate the information to be instructed, and for the receiver of the instruction information, the instruction information can be used to determine the information to be instructed.

[0107] In this application, unless otherwise specified, the same or similar parts between the various embodiments can be referred to each other. In the various embodiments of this application, and in the various implementation methods / methods / implementations within each embodiment, unless otherwise specified or logically conflicting, the terminology and / or descriptions between different embodiments and between the various implementation methods / methods / implementations within each embodiment are consistent and can be mutually referenced. The technical features in different embodiments and the various implementation methods / methods / implementations within each embodiment can be combined according to their inherent logical relationships to form new embodiments, implementation methods, methods, or implementation approaches. The embodiments described below do not constitute a limitation on the scope of protection of this application.

[0108] To facilitate understanding of the methods provided in the embodiments of this application, the system architecture of the methods provided in the embodiments of this application will be described below. It is understood that the system architecture described in the embodiments of this application is for the purpose of more clearly illustrating the solutions of the embodiments of this application and does not constitute a limitation on the solutions provided in the embodiments of this application.

[0109] In one possible implementation, this application can be applied to narrowband Internet of Things (NB-IoT) systems, Global System for Mobile Communications (GSM), Enhanced Data Rate for GSM Evolution (EDGE), Wideband Code Division Multiple Access (WCDMA), Code Division Multiple Access 2000 (CDMA2000), Time Division-Synchronization Code Division Multiple Access (TD-SCDMA), Integrated Sensing and Communication (ISAC) systems, Wireless Local Area Networks (WLANs), Short-Range Wireless Communication Systems (such as sidelinks, Wireless Fidelity (Wi-Fi or WiFi), Bluetooth, etc.), Wired Networks, Vehicle-to-Everything (V2X) Communication Systems, Device-to-Device (D2D) Communication Systems, Vehicle-to-Everything (V2X) Communication Systems, and 4th Generation (4G) communication systems. No restrictions are imposed on mobile communication systems such as LTE (long term evolution), LTE frequency division duplex (FDD), LTE time division duplex (TDD), WiMAX (worldwide interoperability for microwave access), 5G (5th generation) mobile communication systems such as NR (new radio), future NR wireless communication systems, or other similar communication systems.For example, this application can be applied to orthogonal frequency division multiplexing (OFDM) systems in LTE, OFDM systems in NR, and future OFDM systems and similar systems. For instance, this application can be applied to the three major application scenarios of next-generation 5G mobile communication systems: enhanced mobile broadband (eMBB), ultra-reliable low latency communication (URLLC), and / or enhanced machine-type communication (eMTC).

[0110] Please refer to Figure 3a, which is a schematic diagram of the architecture of the communication system 1000 used in the embodiments of this application. As shown in Figure 3a, the communication system includes a RAN 100 and a core network 200. Optionally, the communication system 1000 may also include an Internet 300. The RAN 100 includes at least one RAN node (110a and 110b in Figure 3a, collectively referred to as 110), and may also include at least one terminal (120a-120j in Figure 3a, collectively referred to as 120). The RAN 100 may also include other RAN nodes, such as wireless relay devices and / or wireless backhaul devices (not shown in Figure 3a). The terminal 120 is wirelessly connected to the RAN node 110, and the RAN node 110 is wirelessly or wiredly connected to the core network 200. The core network equipment in the core network 200 and the RAN node 110 in the RAN 100 can be independent and different physical devices, or they can be the same physical device integrating the logical functions of the core network equipment and the logical functions of the RAN node. Terminals can be connected to each other, as can RAN nodes, via wired or wireless means.

[0111] Please refer to Figure 3b, which illustrates an example diagram of an O-RAN system applied in an embodiment of this application. The O-RAN system may include other components besides those shown in the figure. As shown, the access network device (such as a RAN device, for example, an eNB, gNB, or next-generation access network device) communicates with the core network (CN) via a backhaul link and with the UE via an air interface. The O-RAN system may include other components besides those shown in Figure 3b.

[0112] As shown in the figure, the access network equipment (RAN, such as eNB, gNB, or next-generation access network equipment) communicates with the core network (CN) through the backhaul link and with the user equipment (UE) through the air interface.

[0113] Specifically, the baseband unit (BBU) in the access network equipment communicates with the core network via a backhaul link, and the radio unit (RU) in the access network equipment communicates with at least one UE via an air interface. The BBU communicates with at least one RU via a fronthaul link. The BBU and RU may or may not be co-located.

[0114] The BBU includes at least one Control Unit (CU) and at least one Distributed Unit (DU), which can communicate via at least one midhaul link.

[0115] Figure 4 shows the network element function division and protocol layer structure of an O-RAN device.

[0116] In some examples, the CU is a logical node carrying the Radio Resource Control (RRC) layer, Service Data Adaptation Protocol (SDAP) layer, Packet Data Convergence Protocol (PDCP) layer, and other control functions of the access network equipment. The CU connects to network nodes such as the core network through interfaces, which can be interfaces such as E2 interfaces. Optionally, the CU may have some core network functions. The CU (e.g., the PDCP layer and higher layers) connects to the DU (e.g., the RLC layer and lower layers) through interfaces, which can be interfaces such as the F1 interface. In some examples, these interfaces (e.g., the F1 interface) can provide control plane (C-Plane) and user plane (U-Plane) functions (e.g., interface management, system information management, UE context management, RRC message transmission, etc.). F1AP is the application protocol of the F1 interface, defining the F1 signaling procedures in some examples. The F1 interface supports control plane F1-C and user plane F1-U.

[0117] In some examples, a DU is a logical node that carries the Radio Link Control (RLC) layer, Medium Access Control (MAC) layer, Higher Physical Layer (Higher PHY) layer, and other functions. In some examples, a DU can control at least one RU. The DU connects to the RU through interfaces, which can be fronthaul interfaces.

[0118] In some examples, the CU may not have a PDCP layer, i.e., it only includes the RRC layer. CU-CP does not have PDCP-C. CU-UP may not have PDCP-U, or may not have CU-UP at all. In some examples, the DU may not have an RLC layer, only a MAC and a higher PHY layer. Furthermore, in some examples, it may not have a CU and may only include the DU.

[0119] Please refer to Table 2. The O-RAN system may also include the following functions / nodes:

[0120] Table 2

[0121] It should be understood that the above system application scenarios are only examples, and this application can also be applied to other scenarios, which will not be listed here.

[0122] Currently, an increasing number of scenarios require the transmission of uplink data. Uplink data refers to data sent from a user device to a network device (such as a base station) or server. For example, data sent during email transmission, file uploads, or form submissions all fall under the category of uplink data. This data is transmitted over the network from the user device's network interface to the target server or network device.

[0123] When uplink data needs to be transmitted, the UE sends a scheduling request (SR) to the base station on the physical uplink control channel (PUCCH), thereby requesting uplink authorization from the base station. Upon receiving the SR, the base station responds by instructing the UE to send scheduling information via the physical downlink control channel (PDCCH). The base station schedules the UE based on a small, fixed amount of data. After receiving the scheduling instruction, the UE transmits information on the resources allocated by the base station. This transmitted information includes a buffer status report (BSR), which informs the base station how much data remains to be transmitted. If the base station receives a BSR indicating that the UE still has remaining uplink data to transmit, the base station will continue to allocate resources to the UE and instruct the UE to transmit data on the corresponding resources. When the amount of data the UE needs to transmit is large, this scheduling method has low data transmission efficiency.

[0124] Therefore, improving data transmission efficiency is a technical problem that urgently needs to be solved.

[0125] To address the aforementioned problems, this application provides a communication method 100, which will be described in detail below with reference to the accompanying drawings.

[0126] Please refer to Figure 5, which is a schematic diagram of an implementation of the method 100 provided in this application.

[0127] It should be understood that in method 100, the method flowchart uses different communication devices (e.g., the interaction between the first device and the second device) as examples to illustrate the execution subject of the interaction, but this application does not limit the execution subject of the interaction. For example, any communication device (e.g., the first device, the second device, or the third device) can be a communication device, or a chip, baseband chip, modem chip, system-on-a-chip (SoC) chip containing a modem core, system-in-package (SIP) chip, communication module, chip system, processor, logic module, or software in the communication device. Optionally, the communication device can be a terminal device or a network device (e.g., the network device can be an access network device, access network element, etc.).

[0128] As an example, in Figure 5, the first device can be a terminal device and the second device can be a network device. For example, the network device can be an access network device or a communication device in an ORAN system (e.g., at least one of CU, DU, RU).

[0129] In Figure 5, the method 100 provided in this application includes the following steps:

[0130] S501: The first device sends the first SR, and correspondingly, the second device receives the first SR;

[0131] The first SR indicates the resources scheduled for data transmission, and the first SR indicates the first characteristics of the data, including: the data volume is greater than a first threshold or the data transmission latency requirement is lower than a second threshold.

[0132] Optionally, the first SR indicates that the resources scheduled for transmission may be uplink data. The first device may send the first SR when transmitting data or when it is predicted that data transmission is needed to instruct the resources scheduled for data transmission.

[0133] Optionally, prior to S501, the first device can predict the amount of data to be transmitted at time T, the arrival time of the data, or the required latency for data transmission. When the predicted amount of data to be transmitted at time T exceeds a first threshold and / or the required latency for data transmission exceeds a second threshold, the first device can execute S501. Taking Figure 6 as an example, the first device can predict the buffer size, where the buffer size refers to the size of the buffer where data is stored, i.e., the space that can store data. The first device can also predict the arrival time of data, etc.

[0134] Optionally, in this application, the first device can divide the data into different levels according to the size of the data:

[0135] For example, data can be divided into two levels: Level 1: data volume greater than a first threshold; Level 2: data volume not greater than the first threshold. Accordingly, when the data volume to be transmitted exceeds the first threshold, the first SR can be used to indicate that the data possesses the aforementioned first characteristic. Upon receiving the first SR, the second device will allocate a larger PUSCH resource to the first device. Conversely, when the data volume to be transmitted is not greater than the first threshold, the first SR can be used to indicate that data transmission is required. Accordingly, upon receiving the first SR, the second device will allocate a smaller PUSCH resource to the first device.

[0136] For example, the data can be divided into four levels: Level 1: Data volume > Threshold 3; Level 2: Threshold 3 < Data volume < Threshold 2; Level 3: Threshold 1 < Data volume < Threshold 3; Level 4: Data volume < Threshold 1. In this case, when the data volume > Threshold 3, the first SR (Static Reference Scale) can be used to indicate that the data belongs to Level 1; when the data volume > Threshold 3 and the data volume < Threshold 2, the first SR can be used to indicate that the data belongs to Level 2, and so on.

[0137] Optionally, in this application, there is an association between the first SR and the first feature. When the second device receives the first SR, the second device can determine, based on the first SR, that the data to be transmitted by the first device possesses the first feature. To indicate the association between the first SR and the first feature, this application provides several optional examples, as follows:

[0138] Example 1: The first SR includes first indication information and second indication information. The first indication information is used to indicate that data transmission is required, and the second indication information is used to indicate that the data volume is greater than the first threshold and / or the latency requirement for the data transmission is lower than the second threshold.

[0139] Based on the above example, the first SR can directly indicate that the data volume is greater than the first threshold and / or the data transmission latency requirement is lower than the second threshold. Therefore, the second device can directly determine from the first SR that the data volume to be transmitted is large and / or the data transmission latency requirement is high, thereby allocating more PUSCH resources to the first device or increasing the priority of resource allocation to the first device, thus improving the data transmission efficiency of the first device. In the above example, the methods for determining the data volume characteristics and data transmission latency requirements of the interactive data are relatively simple, direct, and efficient.

[0140] Optionally, the SR (e.g., the first SR) in this application may include two bits. For example, the first bit is used to indicate that data transmission is required, and the second bit indicates whether the data amount is greater than a first threshold and / or whether the data transmission latency requirement is lower than a second threshold. For example, first bit = 0 means that data transmission is not required, first bit = 1 means that data transmission is required, second bit = 0 means that the data amount is greater than the first threshold and / or the data transmission latency requirement is lower than the second threshold, and second bit = 1 means that the data amount is not greater than the first threshold and / or the data transmission latency requirement is not lower than the second threshold.

[0141] Optionally, the SR (e.g., the first SR) in this application may include three bits. For example, the first bit indicates that data transmission is required, the second bit indicates whether the data volume is greater than a first threshold, and the third bit indicates whether the data transmission latency requirement is lower than a second threshold. For example, first bit = 0 means no data transmission is required, first bit = 1 means data transmission is required, second bit = 0 means the data volume is greater than the first threshold, second bit = 1 means the data volume is not greater than the first threshold, third bit = 0 means the data transmission latency requirement is lower than the second threshold, and third bit = 1 means the data transmission latency requirement is not lower than the second threshold.

[0142] Optionally, in this example, the physical layer sequence can be designed such that the first indication information in the first SR is used to indicate that data transmission is required, and the second indication information is used to indicate that the data volume is greater than the first threshold and / or the latency requirement for the data transmission is lower than the second threshold.

[0143] Example 2: The first device receives the second information, and accordingly, the second device sends the second information, which indicates that the second resource is used to carry the first type of SR, and the first type of SR indicates the resource for scheduling data that satisfies the first feature; the first device sends the first SR on the second resource, and accordingly, the second device sends the first SR on the second resource.

[0144] Based on the above example, the first device can carry the first type of SR through a dedicated resource, namely the second resource, that is, the SR that carries the resource used to schedule data that meets the first characteristic. Thus, when the second device receives an SR sent through the second resource, it can determine that data that meets the first characteristic needs to be transmitted, thereby allocating more PUSCH resources to the first device or increasing the priority of allocating resources to the first device, thereby improving the data transmission efficiency of the first device.

[0145] Optionally, the second device configures multiple dedicated SR resources for the first device, each corresponding to a different level of data volume. For example, SR1 can be used to carry the first level of data, where the first level of data volume is greater than threshold 3; SR2 can be used to carry the second level of data, where threshold 3 is less than the second level of data volume and threshold 2; SR3 can be used to carry the third level of data, where threshold 1 is less than the third level of data volume and threshold 3.

[0146] Optionally, the network configures multiple dedicated SR resources for the UE, each corresponding to a different level of latency requirements. For example, SR4 can be used to carry first-type data, where the latency requirement for first-type data is less than threshold 4; SR5 can be used to carry second-type data, where threshold 4 is less than the latency requirement for first-type data and threshold 5; SR6 can be used to carry third-type data, where threshold 5 is less than the latency requirement for third-type data and threshold 6.

[0147] Optionally, the second device may send RRC reconfiguration information to the first device, the RRC reconfiguration information carrying the second information.

[0148] Optionally, the second information can be scheduling request configuration information (SchedulingRequestResourceConfig).

[0149] Optionally, the second resource can only be used to carry the first type of SR. Taking Figure 7 as an example, the logical channel identity (LCID) of 3 is configured to send SRs with a scheduling request identity (SR ID) of 3 or SR ID of 2. The SR with SR ID of 3 can be used to request resource 3, which is a dedicated resource. This dedicated resource is used to send the first type of SR. This SR indicates a specific buffer size or a specific delay requirement. In this embodiment, the SR carried by the dedicated resource is used to indicate the resource for scheduling data that meets the first characteristic.

[0150] Optionally, a specific logical channel group (LCG) can be configured to trigger an SR with SR ID 3. For example, a logical channel group with logical channel group identity (LCG ID) of 1, and an SR with SR ID 3 can be used to request resource 3, which is a dedicated resource used to send a first type of SR, indicating a specific buffer size or a specific delay requirement.

[0151] S502: The first device receives the first information obtained based on the first SR;

[0152] Accordingly, the second device sends first information; wherein the first information is used to indicate the first resource.

[0153] Optionally, after receiving the first SR, the second device may request the second device to allocate resources for transmitting data, and accordingly, the second device sends the first information.

[0154] Optionally, the first piece of information is scheduling information.

[0155] Optionally, the first information is a digital copyright identifier (DCI), which is sent on the PDCCH, or it is used to indicate scheduling information.

[0156] Optionally, the first information can be used to indicate the location of the first resource. The location of the first resource includes: the time domain location or the frequency domain location of the first resource.

[0157] Optionally, after the second device receives the first SR, if the amount of data indicated by the first SR is greater than the first threshold, the second device schedules resources for the first device with a larger amount of data. If the latency requirement of the data indicated by the first SR is less than the second threshold, the second device increases the resource scheduling priority of the first device so as to schedule resources for the first device to transmit data in a timely manner.

[0158] Optionally, the first information can be PDCCH indicating scheduling information.

[0159] Optionally, the first information can be used to indicate the location of the first resource. The location of the first resource includes: the time domain location or the frequency domain location of the first resource.

[0160] Optionally, if the number of SR requests by the UE does not reach the maximum value, the first resource can be PUCCH; if the number of SR requests by the UE reaches the maximum value, the first information can be used to indicate the physical random access channel (PRACH).

[0161] S503: The first device sends the first data on the first resource based on the first information.

[0162] Accordingly, the second device receives the first data on the first resource.

[0163] It is understood that the first device can indicate a first resource through first information, such as the time-domain location and frequency-domain location of the first resource, and then the first device can send data on the first resource according to the first information. In an optional implementation, the first device sends a first scheduling request configuration information (BSR), which includes: first time information or a data transmission delay requirement, the first time information indicating the expected time for data transmission; the first device receives third information based on the first BSR, the third information indicating a third resource; and the first device sends second data on the third resource according to the third information.

[0164] Based on the above implementation, the first device can notify the second device of the expected time to send data through the first BSR, so that the second device can perform resource scheduling planning in advance and schedule resources for the first device to transmit data in a timely manner, thereby improving the efficiency of the first device in transmitting data; and / or the first device can notify the second device of the latency requirements for data transmission through the first BSR. When the latency requirements for data transmission are high, the second device can increase the priority of the first device's resource scheduling, thereby scheduling resources for the first device to transmit data in a timely manner, thereby improving the efficiency of the first device in transmitting data.

[0165] Optionally, the first time information can be the expected time of data transmission, or it can be a duration, which is the difference between the expected time of data transmission and the current time. For example, the first time information can be an offset, where the expected time of data transmission is T+offset, and T is the current time. For example, the offset can be 10ms.

[0166] Optionally, the offset can be sent to the first device in advance by the network side, such as the second device, and the first device can trigger the first BSR using the offset as the maximum prediction time period.

[0167] Optionally, the latency requirement for data transmission included in the first BSR can be the minimum latency requirement for data transmission at the expected time of data transmission.

[0168] Optionally, the first BSR may also include the amount of data to be transmitted, which may be the predicted data to be transmitted and / or the data to be transmitted at the current moment.

[0169] Optionally, the first BSR can be carried in a MAC protocol data unit (PDU).

[0170] Optionally, the first device can also send a power headroom report (PHR) to the second device, which is used to inform the second device of the current power headroom.

[0171] As described above, in this application, the first device needs to send data. For example, the first device can be a terminal device, and the second device can be a base station. The first device needs to send uplink data to the second device. To send data, the first device sends a first SR, which indicates the resources to be scheduled for data transmission. In this application, the first characteristic of the data indicated by the first SR includes: the data volume is greater than a first threshold or the data transmission latency requirement is lower than a second threshold. Thus, the device receiving the first SR can determine that the data volume to be transmitted by the first device is large and the data transmission latency is high. The first device receives first information based on the first SR, which is used to indicate a first resource. The first device sends first data on the first resource according to the first information. In this application, the first SR can notify the device receiving the first SR that the data volume to be transmitted is large or the data transmission latency is high. The device receiving the first SR can accordingly adjust the resources scheduled for data transmission allocated to the first device to be large, or adjust the priority of resource scheduling for the first device to schedule resources in a timely manner. Thus, the resources available for data transmission by the first device are sufficient, which can avoid data transmission delays due to insufficient resources and improve data transmission efficiency. Furthermore, since there is no need to send a BSR to notify the base station of data volume and / or latency requirements, the time required for the first device to exchange data volume and latency requirements with the base station is shortened, thereby improving data transmission efficiency.

[0172] To improve the transmission efficiency of downlink data, the following options can be used:

[0173] Method a1: The first device monitors second time information, which is the time information of the first data and the time information of the downlink data corresponding to the first data; the first device receives fourth information, which includes the first uplink data; the first device determines the characteristics of the first downlink data based on the second time information and the fourth information, which is the downlink data corresponding to the first uplink data, and the characteristics of the first downlink data include: transmission time or data volume; the first device transmits the characteristics of the first downlink data.

[0174] Based on the above implementation, the first device can predict the characteristics of the downlink data, namely the transmission time and / or data volume of the downlink data. Thus, the first device can send the characteristics of the downlink data to the second device, so that the second device can reasonably arrange the scheduling time according to the characteristics of the downlink data, reserve resources in advance, and schedule sufficient resources for the first device in a timely manner, so as to avoid the first device from experiencing data transmission delays due to insufficient resources and improve the data transmission efficiency of the first device.

[0175] Optionally, when sending the first uplink data, a first association information is also sent, which is used to indicate that the first uplink data and the first downlink data are associated.

[0176] Optionally, when sending the first downlink data, a second association information is also sent, which is used to indicate that the first downlink data is associated with the first uplink data.

[0177] Optionally, the second time information may include: the time when the first data was sent and the time when the corresponding downlink data was received.

[0178] Optionally, in addition to monitoring the second time information, the first device can also monitor the transmission time of other uplink data and the reception time of downlink data. By monitoring the time information of uplink and downlink data, the first device can determine the transmission and reception time pattern of uplink and downlink data, such as how long after uplink data is sent will downlink data be sent.

[0179] In one optional implementation, the fourth information further includes: the service characteristics of the first service or the type of the first uplink data, wherein the first service is the service corresponding to the first uplink data.

[0180] Based on the above implementation, the characteristics of the first downlink data can be determined according to the service characteristics of the first service or the type of the first uplink data. The service characteristics of the first service or the type of the first uplink data can help determine the transmission pattern, data volume, and data transmission latency requirements of the first downlink data, thereby enabling better prediction of the transmission time and data volume of the first downlink data.

[0181] Optionally, the type of the first uplink data may include: video data, image data, or text data, etc.

[0182] Optionally, the service characteristics of the first service may include: the data packet transmission pattern of the first service or the latency requirements of the first service, etc.

[0183] It is understandable that in mode 1, the first device can be enabled to predict the downlink data volume / time based on historical monitoring uplink and downlink data packet information, and the downlink data delay information can be indicated by the first device.

[0184] Method 2: The second device monitors the third time information of the first data and the downlink data corresponding to the first data; the second device receives the fifth information, which includes the second uplink data; the second device determines the characteristics of the second downlink data based on the third time information and the fifth information, the second downlink data being the downlink data corresponding to the second uplink data, and the characteristics of the second downlink data including: transmission time or data volume; the characteristics of the second device transmitting the second downlink data.

[0185] Based on the above implementation, the second device can predict the characteristics of the downlink data, namely the transmission time and / or data volume. Therefore, the second device can rationally arrange scheduling time based on the characteristics of the downlink data, reserve resources in advance, and allocate sufficient resources to the first device in a timely manner. This avoids data transmission delays caused by insufficient resources in the first device, thereby improving the data transmission efficiency of the first device. The second device can also send the characteristics of the downlink data to the first device, allowing the first device to plan ahead and receive the data promptly.

[0186] Taking Figure 8 as an example, the first device can be a user equipment and the second device can be a base station. After the user equipment sends uplink data, the base station can predict the arrival time of downlink data based on the uplink data. For example, the predicted arrival time of downlink data can be T+50ms, where T is the current time and 50ms is the time interval between the arrival time of the data and the current time.

[0187] Optionally, when sending the second uplink data, a third association information is also sent, which is used to indicate that the second uplink data and the second downlink data are associated.

[0188] Optionally, when sending the second downlink data, a fourth association information is also sent, which is used to indicate that the second downlink data is associated with the second uplink data.

[0189] Optionally, the types of the second uplink data include: video data, image data, or text data, etc.

[0190] Optionally, the service characteristics of the second service may include: the data packet sending pattern of the first service or the latency requirements of the first service, etc.

[0191] Understandably, in mode 2, the second device can be enabled to predict downlink data volume / time based on historical monitoring uplink and downlink data packet information, and the second device can be enabled to indicate downlink data latency information.

[0192] In order to solve the above problems, in addition to method 100, this application provides a communication method 200, which will be described in detail below with reference to the accompanying drawings.

[0193] Please refer to Figure 9, which is a schematic diagram of an implementation of the method 200 provided in this application.

[0194] It should be understood that in method 200, the method flowchart uses different communication devices (e.g., the interaction between the third and fourth devices) as examples to illustrate the execution subject of the interaction, but this application does not limit the execution subject of the interaction. For example, any communication device (e.g., the third device, the fourth device, or the third device) can be a communication device, or a chip, baseband chip, modem chip, system-on-a-chip (SoC) chip containing a modem core, system-in-package (SIP) chip, communication module, chip system, processor, logic module, or software in the communication device. Optionally, the communication device can be a terminal device or a network device (e.g., the network device can be an access network device, access network element, etc.).

[0195] As an example, in Figure 9, the third device can be a network device and the fourth device can be a terminal device. For example, the network device can be an access network device or a communication device in an ORAN system (e.g., at least one of CU, DU, RU).

[0196] In Figure 9, the method 200 provided in this application includes the following steps:

[0197] S901: The third device sends the second BSR.

[0198] Accordingly, the fourth device receives a second BSR. The second BSR indicates the resources scheduled for data transmission, and the second BSR indicates that the data possesses a second characteristic including: the data transmission latency requirement is higher than a third threshold.

[0199] Optionally, as shown in Figure 10, the second BSR may include: LCG ID, buffer size, offset, or latency requirement. The latency requirement for data transmission included in the second BSR can be the minimum latency requirement for data transmission at the expected time of data transmission; the data to be transmitted can be the predicted data to be transmitted and / or the data to be transmitted at the current time.

[0200] Optionally, the LCG ID mentioned above can be replaced with LCID, meaning that the second BSR may include LCID.

[0201] Optionally, the offset in the second BSR is a duration. This duration is the difference between the expected time of data transmission and the current time. For example, the offset can be 20ms. Optionally, the offset in the second BSR can be replaced with the expected time of data transmission. For example, the expected time of data transmission is T+offset, where T is the current time.

[0202] Optionally, the offset can be sent in advance by the network side, such as a fourth device, to the third device, which uses this offset as the maximum prediction time period to trigger the second BSR.

[0203] Optionally, the latency requirement for data transmission included in the second BSR can be the minimum latency requirement for data transmission at the expected time of data transmission.

[0204] Optionally, the second BSR can be carried in the MAC PDU.

[0205] Optionally, the third device can also send a PHR to the fourth device, which is used to notify the second device of the current power margin.

[0206] Optionally, in this application, data can be divided into different levels based on different data latency requirements:

[0207] For example, data can be divided into two levels: Level 1: data transmission latency is required to be below the threshold of 7; Level 2: data transmission latency is not required to be below the threshold of 7.

[0208] In one alternative implementation, a third device receives seventh information indicating that a fifth resource is used to send a second type of BSR, the fifth resource being a periodic resource, and the second type of BSR indicating a resource for scheduling data that satisfies the second characteristic; the third device then sends the second BSR on the fifth resource. Correspondingly, a fourth device sends the seventh information and receives the second BSR on the fifth resource.

[0209] Based on the above implementation, the third device can send the second BSR through a dedicated channel, namely the first channel. The resources scheduled by the BSR sent through the first channel are used to transmit data that meets the second characteristic. That is, there is a correlation between the first channel and the second characteristic. Once the fourth device receives the BSR sent through the second channel, it knows that the data to be transmitted has the second characteristic, and thus promptly schedules resources for the third device to improve the data transmission efficiency of the third device.

[0210] The above implementation method is suitable for situations where the data transmission pattern, data volume, or latency requirements cannot be predicted.

[0211] Optionally, the fourth device may send the period of the periodic resource to the third device, which is the period during which the third device sends the second type of BSR using the fifth resource.

[0212] Optionally, the periodic resource is configured for a first channel group, which is a logical channel group.

[0213] Optionally, the fourth device can send a DCI / MAC control element (CE) to activate the periodic resource.

[0214] Optionally, the third device may send a request message to the fourth device, which requests the fourth device to configure the periodic resource.

[0215] Optionally, when the third device has other uplink resources available for sending the BSR, it may not send the BSR on the first transmitter.

[0216] Optionally, the period for sending the second BSR can also be associated with the longest time predicted by the terminal.

[0217] Optionally, a second BSR can be periodically sent after the first / in-path BSR is sent.

[0218] Optionally, the second BSR may begin to be sent periodically only when the amount of burst uplink data packets is greater than the threshold X and / or the latency requirement is less than Y.

[0219] S902: The third device receives the sixth information based on the second BSR;

[0220] The sixth piece of information is used to instruct the fourth resource.

[0221] Optionally, after the fourth device receives the second BSR, since the sixth information indicates that the data transmission delay requirement is higher than the third threshold, the fourth device increases the resource scheduling priority of the third device so as to schedule resources for the third device to transmit data.

[0222] Optionally, this sixth piece of information can be PDCCH indicating scheduling information.

[0223] Optionally, this sixth piece of information can be used to indicate the location of the first resource. The location of the first resource includes: the time-domain location or the frequency-domain location of the first resource.

[0224] S903: The third device sends third data on the fourth resource based on the sixth information.

[0225] Accordingly, the fourth device transmits third data on the fourth resource.

[0226] It is understood that the fourth device can indicate the first resource through the sixth information, such as the time domain location and frequency domain location of the first resource, and then the third device can send data on the first resource according to the sixth information.

[0227] As described above, the third device enables a specific BSR trigger network, allowing the fourth device to rationally allocate resources for the UE to meet the high latency or high data volume requirements of uplink data transmission. To improve downlink data transmission efficiency, the following optional methods can be used:

[0228] Method b1: The third data is uplink data. The third device monitors the fourth time information, which includes the time information of the third data and the time information of the downlink data corresponding to the third data. The third device sends the eighth information, which includes the third uplink data. The third device determines the characteristics of the third downlink data based on the fourth time information and the eighth information. The third downlink data is the downlink data corresponding to the third uplink data. The characteristics of the third downlink data include the transmission time or data volume. The third device transmits the characteristics of the third downlink data.

[0229] Based on the above implementation, the third device can predict the characteristics of the downlink data, namely the transmission time and / or data volume of the downlink data. Thus, the third device can send the characteristics of the downlink data to the fourth device, so that the fourth device can reasonably arrange the scheduling time according to the characteristics of the downlink data, reserve resources in advance, and schedule sufficient resources for the third device in a timely manner to avoid the third device from experiencing data transmission delays due to insufficient resources, thereby improving the data transmission efficiency of the third device.

[0230] Optionally, when sending the third uplink data, a fifth association information is also sent, which is used to indicate that the third uplink data and the third downlink data are associated.

[0231] Optionally, when sending the third downlink data, a sixth association information is also sent, which is used to indicate that there is an association between the third downlink data and the third uplink data.

[0232] Optionally, the fourth time information may include: the time when the third data was sent and the time when the corresponding downlink data was received.

[0233] Optionally, in addition to monitoring the fourth time information, the third device can also monitor the transmission time of other uplink data and the reception time of downlink data. By monitoring the time information of uplink and downlink data, the third device can determine the transmission and reception time patterns of uplink and downlink data, such as how long after uplink data is sent will downlink data be sent.

[0234] In one optional implementation, the fourth information further includes: the business characteristics of the third service or the type of the third uplink data, wherein the third service is the service corresponding to the third uplink data.

[0235] Based on the above implementation, the characteristics of the third downlink data can be determined according to the service characteristics of the third service or the type of the third uplink data. The service characteristics of the third service or the type of the third uplink data can help determine the transmission pattern, data volume, and data transmission latency requirements of the third downlink data, thereby enabling better prediction of the transmission time and data volume of the third downlink data.

[0236] Optional, the types of third-uplink data include: video data, image data, or text data, etc.

[0237] Optionally, the service characteristics of the third service include: the data packet transmission pattern of the third service or the latency requirements of the third service, etc.

[0238] It is understandable that in mode 1, the third device can be enabled to predict the downlink data volume / time based on historical monitoring uplink and downlink data packet information, and the downlink data delay information can be indicated by the third device.

[0239] Method b2: The third data is uplink data; the fourth device monitors the fifth time information of the third data and the downlink data corresponding to the third data; the fourth device receives the ninth information, which includes the fourth uplink data; the fourth device determines the characteristics of the fourth downlink data based on the fourth time information and the ninth information, the fourth downlink data being the downlink data corresponding to the fourth uplink data, and the characteristics of the fourth downlink data including: transmission time or data volume; the characteristics of the fourth device transmitting the fourth downlink data.

[0240] Based on the above implementation, the fourth device can predict the characteristics of the downlink data, namely the transmission time and / or data volume. Therefore, the fourth device can rationally arrange scheduling time based on the characteristics of the downlink data, reserve resources in advance, and allocate sufficient resources to the third device in a timely manner. This avoids data transmission delays caused by insufficient resources in the third device, thereby improving the data transmission efficiency of the third device. The fourth device can also send the characteristics of the downlink data to the third device, allowing the third device to plan ahead and receive the data promptly.

[0241] For example, the third device can be a user equipment, and the fourth device can be a base station. After the user equipment sends uplink data, the base station can predict the arrival time of downlink data based on the uplink data. For example, the predicted arrival time of downlink data can be T+50ms, where T is the current time and 60ms is the time interval between the data arrival time and the current time.

[0242] Optionally, when sending the fourth uplink data, a seventh association information is also sent, which is used to indicate that the fourth uplink data and the fourth downlink data are associated.

[0243] Optionally, when sending the fourth downlink data, an eighth association information is also sent, which is used to indicate that the fourth downlink data and the fourth uplink data are associated.

[0244] Optional, the types of fourth uplink data include: video data, image data, or text data, etc.

[0245] Optionally, the service characteristics of the fourth service include: the data packet transmission pattern of the fourth service or the latency requirements of the fourth service, etc.

[0246] It is understandable that in mode 2, the fourth device can be enabled to predict the downlink data volume / time based on historical monitoring uplink and downlink data packet information, and the delay information of the downlink data can be indicated by the fourth device.

[0248] S1101: The first device predicts the uplink data;

[0249] For example, the first device can predict the amount of uplink data, arrival time, latency requirements, etc. When the predicted amount of uplink data is greater than a first threshold and / or the predicted latency requirements of uplink data are less than a second threshold, S1102 is executed.
