[0025] The technical solution in this application will be described below with reference to the accompanying drawings.

[0026] Communication System

[0027] Figure 1 illustrates a wireless communication system 100 used in an embodiment of the present application. The wireless communication system 100 may include a network device 110 and a terminal device 120. The network device 110 may be a device that communicates with the terminal device 120. The network device 110 may provide communication coverage for a specific geographic area and may communicate with the terminal device 120 within the coverage area.

[0028] Optionally, the wireless communication system 100 may further include other network entities such as a network controller and a mobility management entity, which is not limited in the embodiment of the present application.

[0029] Unlike traditional cellular systems, where data is sent and received via network devices, sideline communication systems (such as the Internet of Vehicles) use direct device-to-device communication. As a result, sideline communication offers higher spectral efficiency and lower transmission latency.

[0030] The following describes several common sidelink communication scenarios in conjunction with Figure 2. In sidelink communication system 200, three scenarios can be categorized based on whether the sidelink communication terminal is within the coverage of the network device. Scenario 1: The terminal conducts sidelink communication within the coverage of the network device. Scenario 2: Some terminals conduct sidelink communication within the coverage of the network device. Scenario 3: The terminal conducts sidelink communication outside the coverage of the network device.

[0031] As shown in Figure 2, in scenario 1, terminals 221-222 can communicate via a sidelink, and terminals 221-222 are all within the coverage of network device 210, or in other words, terminals 221-222 are all within the coverage of the same network device 210. In this scenario, network device 210 can send configuration signaling to terminals 221-222, and accordingly, terminals 221-222 communicate via the sidelink based on the configuration signaling.

[0032] As shown in Figure 2, in scenario 2, terminals 223 and 224 can communicate via a sidelink, and terminal 223 is within the coverage of network device 210, while terminal 224 is outside the coverage of network device 210. In this scenario, terminal 223 receives configuration information from network device 210 and communicates via a sidelink based on the configuration signaling. However, for terminal 224, since terminal 224 is outside the coverage of network device 210, it cannot receive the configuration information of network device 210. In this case, terminal 224 can obtain the configuration of the sidelink communication based on the configuration information according to pre-configuration and / or the configuration information sent by terminal 223 within the coverage area, so as to communicate with terminal 223 via the sidelink based on the obtained configuration.

[0033] In some cases, terminal 223 may send the above configuration information to terminal 224 via a physical sidelink broadcast channel (PSBCH) to configure terminal 224 to communicate via the sidelink.

[0034] As shown in Figure 2, in scenario 3, terminals 225-229 are all outside the coverage of network device 210 and cannot communicate with network device 210. In this case, the terminals can configure sidelink communication based on pre-configuration information.

[0035] In some cases, terminals 227-229 located outside the coverage area of ​​the network device can form a communication group, and the terminals 227-229 in the communication group can communicate with each other. In addition, terminal 227 in the communication group can serve as a central control node, also known as a cluster header (CH), and correspondingly, the terminals in other communication groups can be called "group members."

[0036] Terminal 227 as a CH may have one or more of the following functions: responsible for establishing a communication group; joining and leaving group members; coordinating resources, allocating side transmission resources to group members, receiving side transmission feedback information from group members; coordinating resources with other communication groups, etc.

[0037] It should be noted that Figures 1 and 2 exemplarily show a network device and multiple terminal devices. Optionally, the wireless communication system 100 and the wireless communication system 200 may both include multiple network devices and the coverage range of each network device may include other numbers of terminal devices. This embodiment of the present application does not limit this.

[0038] It should be understood that the technical solutions of the embodiments of the present application can be applied to various communication systems, such as: fifth generation (5G) system or new radio (NR), long term evolution (LTE) system, LTE frequency division duplex (FDD) system, LTE time division duplex (TDD), etc. The technical solutions provided in this application can also be applied to future communication systems, such as the sixth generation mobile communication system, satellite communication system, etc.

[0039] The terminal device in the embodiments of the present application may also be referred to as user equipment (UE), access terminal, user unit, user station, mobile station, mobile station (MS), mobile terminal (MT), remote station, remote terminal, mobile device, user terminal, terminal, wireless communication device, user agent or user device. The terminal device in the embodiments of the present application may refer to a device that provides voice and / or data connectivity to a user and can be used to connect people, objects and machines, such as a handheld device with wireless connection function, a vehicle-mounted device, etc. The terminal device in the embodiments of the present application can be a mobile phone, a tablet computer, a laptop computer, a PDA, a mobile internet device (MID), a wearable device, a virtual reality (VR) device, an augmented reality (AR) device, a wireless terminal in industrial control, a wireless terminal in self-driving, a wireless terminal in remote medical surgery, a wireless terminal in a smart grid, a wireless terminal in transportation safety, a wireless terminal in a smart city, a wireless terminal in a smart home, etc. Optionally, the UE can be used to act as a base station. For example, the UE can act as a scheduling entity that provides sidelink signals between UEs in vehicle-to-everything (V2X) or device-to-device (D2D). For example, a cellular phone and a car communicate with each other using sidelink signals. The cellular phone and smart home devices communicate without relaying the communication signal through a base station.

[0040] The network device in the embodiments of the present application may be a device for communicating with a terminal device, and may also be referred to as an access network device or a radio access network device. For example, the network device may be a base station. The network device in the embodiments of the present application may refer to a radio access network (RAN) node (or device) that connects a terminal device to a wireless network. A base station may broadly cover various names as follows, or be replaced with the following names, such as: NodeB, evolved NodeB (eNB), next generation NodeB (gNB), relay station, access point, transmitting and receiving point (TRP), transmitting point (TP), master eNB (MeNB), secondary eNB (SeNB), multi-standard radio (MSR) node, home base station, network controller, access node, wireless node, access point (AP), transmission node, transceiver node, baseband unit (BBU), remote radio unit (RRU), active antenna unit (AAU), remote radio head (RRH), central unit (CU), distributed unit (DU), positioning node, etc. A base station may be a macro base station, a micro base station, a relay node, a donor node, or the like, or a combination thereof. A base station may also refer to a communication module, modem, or chip used to be set in the aforementioned device or apparatus. A base station may also be a mobile switching center and a device that performs base station functions in D2D, V2X, and machine-to-machine (M2M) communications, a network-side device in a 6G network, or a device that performs base station functions in future communication systems. A base station may support networks with the same or different access technologies. The embodiments of this application do not limit the specific technology and specific device form adopted by the network equipment.

[0041] Base stations can be fixed or mobile. For example, a helicopter or drone can be configured to act as a mobile base station, and one or more cells can move based on the location of the mobile base station. In other examples, a helicopter or drone can be configured to act as a device that communicates with another base station.

[0042] In some deployments, the network device in the embodiments of the present application may refer to a CU or a DU, or the network device includes a CU and a DU. The gNB may also include an AAU.

[0043] The network equipment and terminal devices can be deployed on land, including indoors or outdoors, handheld or vehicle-mounted; they can also be deployed on water; they can also be deployed in the air on aircraft, balloons, and satellites. The embodiments of this application do not limit the scenarios in which the network equipment and terminal devices are located.

[0044] It should be understood that all or part of the functions of the communication device in this application can also be implemented through software functions running on hardware, or through virtualization functions instantiated on a platform (such as a cloud platform).

[0045] Sideline communication mode

[0046] Some standards or protocols (such as the 3rd Generation Partnership Project (3GPP)) define two sideline communication modes (or transmission modes): a first mode (mode-1) and a second mode (mode-2).

[0047] In the first mode, the resources of the terminal device (the resources mentioned in this application may also be referred to as transmission resources, such as time-frequency resources) are allocated by the network device. The terminal device may send data on the side link according to the resources allocated by the network device. The network device may allocate resources for a single transmission to the terminal device, or may allocate resources for a semi-static transmission to the terminal device. This first mode may be applied to a scenario covered by a network device, such as the scenario shown in FIG2 . In the scenario shown in FIG2 , the terminal device 221 and the terminal device 222 are located within the network coverage of the network device 210. The network device 210 may allocate resources used in the side transmission process to the terminal device 221 and the terminal device 222. The network device may grant (grant) via a downlink (DL) to allocate resources used in the side transmission process to the terminal device 221 and the terminal device 222, so that the terminal device 221 and the terminal device 222 can communicate on the side link. In some embodiments, the first mode may also be referred to as mode A.

[0048] In the second mode, the terminal device can autonomously select one or more resources in the resource pool (RP). Specifically, the terminal device can select transmission resources in the resource pool by listening, or select transmission resources in the resource pool by random selection. For example, the terminal device 221 is located within the network coverage. The terminal device 221 can autonomously select resources from the preconfigured resource pool for side transmission. Alternatively, the terminal device 221 can autonomously select one or more resources from the resource pool configured by the network device 210 for side transmission. It should be noted that terminal devices outside the network coverage (such as terminal 225) can also use the second mode for resource selection. In some embodiments, the second mode may also be referred to as mode B.

[0049] Radio resource scheduling

[0050] In a communication system, the exemplary process of FIG. 3 may be used to enable a network device to schedule wireless resources for a terminal device so that the terminal device can send data.

[0051] The method shown in FIG. 3 may include steps S310 - S350 .

[0052] Step S310: The terminal device sends a scheduling request to the network device.

[0053] According to the obtained call request message, the network device may schedule the terminal device to send a packet data unit (PDU), that is, the network device may allocate resources to the terminal device for the terminal device to send a PDU.

[0054] Step S320: The network device sends a first scheduling message. The first scheduling message is used to schedule the terminal device to send the above-mentioned PDU.

[0055] In step S330, based on the resources allocated by the network device, the terminal device may send buffer information of the terminal device to the network device. The buffer information may be a buffer status report (BSR). The BSR may be used to indicate how much data is waiting to be sent in the buffer of the terminal device.

[0056] Step S340: Based on the buffer information, the network device sends second scheduling information. The second scheduling information can be used to schedule the terminal device to send data. In other words, the second scheduling information can be used to indicate the wireless resources scheduled by the network device for the data sent by the terminal device.

[0057] Step S350: Based on the second scheduling information, the terminal device may send a data packet.

[0058] Based on the method shown in Figure 3, the radio resources used by the terminal device to send the PDU for buffer information and the PDU for sending data packets are all exclusive to the scheduled terminal device. Therefore, the method shown in Figure 3 can avoid conflicts in the radio resources used by different terminal devices in the same cell.

[0059] However, based on the method shown in Figure 3, the terminal device must perform a handshake process with the network device in steps S310-S340 before sending data. This handshake process can result in longer user-plane latency. For applications where data packets arrive relatively continuously, the PDUs for subsequent data transmissions can also carry buffer information, so latency is not a significant issue. However, for applications where data packets arrive discontinuously, the terminal device will frequently send scheduling requests, introducing additional user-plane latency.

[0060] The above describes a technical solution for network equipment to schedule wireless resources for terminal devices to avoid resource conflicts. This solution is particularly useful when the cell coverage area is large and / or the carrier frequency band used by the cell is relatively low. If the cell is a macrocell with a relatively large coverage area (approximately several hundred meters to tens of kilometers), the number of terminal devices in the cell is often large, making conflict resolution essential. With the continuous evolution of wireless communication systems, new wireless communication systems can not only re-cultivate existing wireless frequency resources but also add new spectrum. For example, 5G systems can re-cultivate frequency bands below 2 GHz used by 2G, 3G, and 4G systems. 5G systems can also deploy extensive networks in new frequency bands, such as 3.5 GHz. A key reason for deploying networks in 3.5 GHz is that 3.5 GHz has a bandwidth exceeding 100 MHz in many countries. To save costs, operators have implemented various measures to ensure that the coverage of the 3.5 GHz band is comparable to that of previous systems, thereby fully utilizing the hardware and infrastructure of existing systems. However, this approach is not applicable to all frequency bands. For example, millimeter wave (mmWave) coverage is limited to hotspots. Due to the limitations of millimeter wave radio wave propagation characteristics, it can only cover a limited area, such as a cell radius of tens of meters. The number of terminal devices served in a cell is much smaller than the number of terminals served in a macro cell.

[0061] When the cell coverage is relatively small, the probability of collision between terminal devices when accessing the same wireless resource pool is greatly reduced. Even if a collision occurs, technical measures can be taken to enhance it, such as adopting a hybrid automatic repeat request (HARQ) retransmission mechanism. Assuming that the current collision probability of the wireless resource pool used by the terminal device is 10% and the HARQ block error rate (BLER) is 0, the success rate of each transmission is 81% (90% * 90%), and the failure rate is 19%. If the maximum number of retransmissions taken by a HARQ process is 2 times (including the initial transmission, a total of 3 times), the probability of not successfully transmitting after 3 transmissions is only 0.6859%. It can be seen that the probability of successful transmission is very high, which is mainly due to the low collision probability of the wireless resource pool.

[0062] In some embodiments, such as the second mode in the sideline communication system described above, the network device can notify the terminal device of the radio resources or resource pool used to send data. When the terminal device has data to send, the terminal device can use these pre-configured radio resources to achieve data transmission, thereby avoiding the need to send a scheduling request. In this case, the network device is uncertain whether the terminal device will send data or the amount of data to be sent by the terminal device. In some embodiments, the network device can configure fewer radio resources for the terminal device, thereby adopting a more conservative resource scheduling algorithm. Alternatively, the network device can configure more radio resources for the terminal device, but the terminal device may not use all of the configured radio resources, resulting in a waste of radio resources.

[0063] It can be seen that there are many problems with the related technology for scheduling resources for terminal devices. These problems may include, for example: long user delay, waste of wireless resources, resource conflicts, etc.

[0064] FIG4 illustrates a communication method provided by an embodiment of the present application to address the aforementioned issues. The method illustrated in FIG4 may be performed by a terminal device and a communication device. The communication device may include a network device and / or other terminal devices. The method illustrated in FIG4 may include steps S410 to S420.

[0065] S410: The terminal device determines whether to select wireless resources on its own.

[0066] This application does not limit the method by which a terminal device determines whether to select a wireless resource on its own. For example, the terminal device may determine whether to select a wireless resource on its own based on a machine learning model. The machine learning model may include, for example, a slot machine algorithm.

[0067] Machine learning models can process more complex input data, allowing terminal devices to more accurately determine whether to select wireless resources based on a variety of factors.

[0068] When the terminal device determines not to select wireless resources on its own, the terminal device may obtain wireless resources based on relevant technologies. For example, the terminal device may obtain wireless resources for sending data according to the schedule of the scheduler.

[0069] If the terminal device determines to independently select a radio resource, the terminal device may independently select a first radio resource from the resource pool. The first radio resource may be part or all of the resources in the resource pool. The resources in the resource pool may be shared by terminal devices within a cell. The resource pool information may be sent to the terminal device by the network device via signaling.

[0070] Based on the present application, whether to self-select wireless resources is determined by the terminal device itself. In some cases, the terminal device can determine to self-select wireless resources, that is, the terminal device can obtain resources for sending data without introducing additional delay. In some cases, the terminal device can determine not to self-select wireless resources, and the scheduler can schedule the terminal device to allocate wireless resources dedicated to the terminal device, thereby avoiding resource conflicts or resource waste. Therefore, based on the present application, the terminal device can determine whether to self-select wireless resources according to different situations, thereby reducing delays and avoiding resource waste to a certain extent.

[0071] Step S420: Based on the first wireless resource, the terminal device sends data and / or buffers data information.

[0072] Buffered data information may also be referred to as buffer status information (BSI). Buffered data information may be used to indicate information about the buffer of a terminal device. The buffer may be used to cache data to be sent, i.e., the data to be sent may be data in the buffer. The buffered data information may, for example, include one or more of the following information about the data cached in the buffer: the size of the data, the relationship between the data and the logical channel, and the remaining delay budget. The remaining delay budget may, for example, indicate how much time remains before a data packet exceeds the delay budget for that data packet.

[0073] In some embodiments, the buffer can receive and store service data units (SDUs) sent by the upper layer protocol. The buffer can belong to a sending entity in the terminal device for sending data. The sending entity can also include the machine learning model and / or sending unit described above. The sending unit can process the SDU to form a packet data unit (PDU). The sending unit can also pass the PDU to the entity corresponding to the next layer protocol of the sending entity for processing. The sending entity can be, for example, a medium access control (MAC) entity, and the entity corresponding to the next layer protocol can be a physical layer protocol entity.

[0074] The communication device that receives data sent by the terminal device and the communication device that receives the buffered data information can be the same or different. For example, the communication device that receives the data can be a first communication device, and the communication device that receives the buffered data information can be a second communication device. That is, the communication device shown in Figure 4 can include the first communication device and / or the second communication device. The first communication device and the second communication device can be the same or different.

[0075] In some embodiments, the first communication device may be a device that communicates with a terminal device. Alternatively, the first communication device may be a device that receives a PDU sent by a terminal device. The first communication device may be, for example, a network device or other terminal device. For example, the data transmitter may be the first terminal device, and the data receiver may be the second terminal device. The first terminal device and the second terminal device may communicate via a sidelink.

[0076] In some embodiments, the second communication device may be a communication device where the scheduler is located. The scheduler may be used to schedule invalid resources for the terminal device. The communication device where the scheduler is located may be a network device. For example, the communication device where the scheduler is located may be a base station or an AP. The AP may be used to establish a local area network. After receiving the cached data information, the communication device where the scheduler is located may schedule the data in the buffer according to the cached data information, thereby scheduling dedicated wireless resources for data transmission for the terminal device, thereby avoiding conflicts in resources for data transmission. Moreover, based on the above method, the terminal device can obtain wireless resources for data transmission without sending a scheduling request, thereby reducing user plane latency.

[0077] If the scheduler schedules radio resources for a terminal device, the scheduler may send a scheduling instruction or scheduling information to the terminal device. If the terminal device receives the scheduling instruction, it may suspend the process of determining whether to select a radio resource on its own and transmit data using the radio resource scheduled by the scheduler. If the terminal device does not receive the scheduling instruction and has data to transmit in its buffer, it may restart the process of determining whether to select a radio resource on its own.

[0078] In some embodiments, the priority of the buffered data information may not be lower than the priority of the data sent by the terminal device. In some embodiments, the sending time of the buffered data information may not be later than the sending time of the data. For example, when resources are limited, the terminal device may send the buffered data information first, and then send the data. When resources are not limited, the terminal device may send data and buffered data information at the same time. In some embodiments, the buffered data information may be placed in the PDU first, and then other content (such as the first data) may be multiplexed. The priority of the buffered data information is higher than the priority of the data sent by the terminal device, which can make it easier for the receiving end to receive the buffered data information, thereby scheduling according to the buffered data information, and thus avoiding resource conflicts in subsequent communications.

[0079] In some embodiments, the terminal device may determine whether to select the wireless resource on its own based on the second information. For example, when the terminal device determines whether to select the wireless resource on its own through a machine learning model, the input information of the machine learning model may include the second information.

[0080] The second information may include one or more of the following information: environmental information outside the terminal device, setting parameters and service information inside the terminal device.

[0081] In some embodiments, the external environment information of the terminal device may include wireless environment information. The wireless environment information may include, for example, one or more of wireless channel congestion information, wireless channel signal-to-noise ratio, and other information. The wireless environment information may be represented in a quantitative manner. For example, wireless channel congestion information may be represented by the percentage of currently used wireless channel resources to total wireless channel resources.

[0082] It should be noted that the wireless environment information may include resource pool information. For example, the wireless environment information may include information on the congestion level of the resource pool.

[0083] In some embodiments, the internal setting parameters of the terminal device may include setting parameters of a buffer of the terminal device, such as the size of the buffer.

[0084] In some embodiments, the service information may include one or more of the following information: a data arrival mode and quality of service (QoS) parameters. The data arrival mode may include one or more of parameters such as data arrival period, jitter, and data packet size. The QoS parameters may be QoS parameters for sending data packets. For example, the QoS parameters may include one or more of parameters such as delay budget and packet loss rate.

[0085] The data sent by the terminal device based on the first wireless resource may be part or all of the data to be sent.

[0086] The data sent by the terminal device may be all or part of the data to be sent. That is, the data sent by the terminal device may be all or part of the data in the buffer. In some embodiments, the data sent by the terminal device is the first data. If the first data is part of the data to be sent, the cached data information may be used to indicate the remaining data to be sent. For example, the first data may be the data that forms the PDU, and the data remaining in the buffer may be the remaining data to be sent. In this case, the information of the data cached in the buffer may be indicated by the cached data information. For example, the cached data information may include one or more of the following information: the size of the remaining data to be sent; the relationship between the remaining data to be sent and the logical channel; the remaining delay budget of the remaining data to be sent.

[0087] After receiving the cached data information, the scheduler obtains the remaining data to be sent in the buffer. Based on this information, the scheduler can schedule the remaining data to be sent, that is, allocate resources for the remaining data to be sent. The resources allocated by the scheduler can be dedicated to the terminal device, thus avoiding resource conflicts when sending the remaining data to be sent.

[0088] In some embodiments, the buffered data information can be multiplexed with the first data in the same PDU. In the case where the communication device where the scheduler is located and the data receiving end are the same communication device, the buffered data information can be multiplexed with the first data in the same PDU, so that the receiving end can receive the buffered data information and the first data at the same time.

[0089] In the case where the terminal device selects the wireless resource independently, the terminal device may also determine third information. The third information may be determined, for example, by a machine learning model. In other words, the third information may be output information of the machine learning model.

[0090] The third information may be used to indicate, for example, the data information of the current transmission, the radio resource information used for the current transmission, etc. For example, the third information may include one or more of the following information: the size of the PDU to be transmitted, the size of the radio resources selectable by the terminal device, etc. The size of the PDU to be transmitted may be represented in bits (bytes). The size of the radio resources selectable by the terminal device may be used to indicate how much radio resources the terminal device should use to transmit the PDU.

[0091] Based on the third information, the terminal device can determine the size of the data to be sent and / or the size of the buffered data information.
