Description

通信方法和通信装置Communication method and communication device 技术领域technical field
本申请涉及通信领域，尤其涉及一种通信方法和通信装置。The present application relates to the field of communication, and in particular, to a communication method and a communication device.
背景技术Background technique
车联网是指按照约定的通信协议和数据交互标准，在车与车、行人、路边设备及互联网之间，进行无线通讯和信息交换的大***网络。通过车联网通信可以使车辆获得行驶安全、提高交通效率以及获得便利或娱乐信息。从无线通信的对象来分类，车联网通信包括三种不同类型：车辆与车辆之间通信(vehicle-to-vehicle，V2V)，车辆与路边设备/网络基础设施之间通信(vehicle-to-infrastructure/vehicle-to-network，V2I/V2N)，以及车辆与行人之间通信(vehicle-to-pedestrian，V2P)，统称为车到万物通信(vehicle to everything，V2X)。V2X是将车辆与一切事物相连接的新一代信息通信技术，其中，V代表车辆，X代表任何与车交互信息的对象，例如包括车、人、交通路侧基础设施和网络。The Internet of Vehicles refers to a large system network for wireless communication and information exchange between vehicles, pedestrians, roadside equipment and the Internet according to agreed communication protocols and data exchange standards. Vehicles can obtain driving safety, improve traffic efficiency, and obtain convenient or entertainment information through vehicle networking communication. Classified from the object of wireless communication, vehicle-to-vehicle communication includes three different types: vehicle-to-vehicle (V2V), vehicle-to-roadside equipment/network infrastructure (vehicle-to- infrastructure/vehicle-to-network, V2I/V2N), and vehicle-to-pedestrian (V2P) communication, collectively referred to as vehicle-to-everything (V2X). V2X is a new generation of information and communication technology that connects vehicles with everything, where V represents the vehicle and X represents any object that interacts with the vehicle, such as vehicles, people, traffic roadside infrastructure and networks.
V2X通信包括多种模式，包括单播(unicast)，组播(groupcast)，广播(broadcast)。目前，采用的V2X组播通信和V2X广播通信方案中，终端设备(例如UE)一直处于收发模式同时启动的状态(即始终监听来自其他装置的消息以及始终发送V2X消息)，会造成不必要的V2X消息传输，进而导致的电能损耗。因此，需要研究更加节能的组播和\或广播通信方案。V2X communication includes various modes, including unicast (unicast), multicast (groupcast), and broadcast (broadcast). At present, in the adopted V2X multicast communication and V2X broadcast communication solutions, terminal equipment (such as UE) is always in the state of sending and receiving mode and starting at the same time (that is, always monitoring messages from other devices and always sending V2X messages), which will cause unnecessary V2X message transmission, resulting in power consumption. Therefore, more energy-efficient multicast and/or broadcast communication schemes need to be studied.

以下将详细介绍本申请涉及的网络架构。The network architecture involved in this application will be introduced in detail below.
本申请提供的技术方案可以应用于各种通信***，例如：第五代(5th generation，5G)通信***或新无线(new radio，NR)以及未来的其他通信***如6G等。下面以5G通信***为例，介绍本申请提供的技术方案。下面先介绍5G网络的相关知识。The technical solutions provided in this application can be applied to various communication systems, for example, fifth generation (5th generation, 5G) communication systems or new radio (new radio, NR) and other future communication systems such as 6G and so on. The following takes the 5G communication system as an example to introduce the technical solution provided by this application. The following is an introduction to the relevant knowledge of 5G network.
随着移动通信技术的更新换代，势必会给各行各业带来许多创新应用，移动宽带、多媒体、机器类通信(machine type communication，MTC)、工业控制、智能交通***(intelligent transportation system，ITS)将成为5G时代的主要用例。为了满足广泛变化的业务需求，5G网络将以灵活的方式构建。其中，一种潜在的方向是网络功能分离，即控制面(control plane function，CP)和用户面(user plane，UP)功能分离，CP中的移动性管理(mobility management，MM)和会话管理(session management，SM)功能分离。With the upgrading of mobile communication technology, it is bound to bring many innovative applications to all walks of life, such as mobile broadband, multimedia, machine type communication (MTC), industrial control, and intelligent transportation system (ITS). Will be the main use case in the 5G era. To meet widely changing business needs, 5G networks will be built in a flexible manner. Among them, a potential direction is the separation of network functions, that is, the separation of control plane (CP) and user plane (UP) functions, and the separation of mobility management (MM) and session management ( session management, SM) function separation.
网络切片技术是将一个物理网络切割成多个虚拟的端到端的网络，每个虚拟网络之间，包括网络内的设备、接入技术、传输路径和核心网，是逻辑独立的。特别是在5G的网络切片(network slice)中，每个网络切片由一个独立的网络功能或功能组合实例化构成，具备不同的功能特点，面向不同的需求和服务。网络切片的分离使得不同用户、用户组可以根据其不同应用场景和需求灵活、动态的定义和定制网络能力，而相互间不影响。Network slicing technology is to cut a physical network into multiple virtual end-to-end networks. Each virtual network, including the devices, access technologies, transmission paths, and core networks within the network, is logically independent. Especially in the 5G network slice, each network slice is composed of an independent network function or function combination instantiation, which has different functional characteristics and faces different needs and services. The separation of network slices enables different users and user groups to flexibly and dynamically define and customize network capabilities according to their different application scenarios and requirements, without affecting each other.

Figure 2 shows a communication scenario under the 5G network architecture. As shown in Figure 2, the V2X communication scenario includes 5G core network (5G core network, 5GC), NG-RAN, V2X application server, and one or more terminal devices. In Figure 2, only one four terminal devices (ie UE A, UE B, UE C, and UED) as examples. NG-RAN refers to 5G Radio Access Network. In this embodiment of the present application, the terminal device may be user equipment, such as a mobile phone, tablet computer, wearable device, etc., or a vehicle, such as a car, a bus, etc., or other devices capable of communicating with vehicles, such as a road Side wireless unit (road side unit, RSU). In Figure 2, the V2X application server is used to provide V2X application services for terminal equipment, and the NG-RAN is used to connect the terminal equipment to the 5G core network or V2X application server. In Figure 2, the NWDAF network element is a network data analysis function network element, which is mainly used to collect relevant data from other network elements in the network, receive data analysis requests from other network elements, and feed back the corresponding data analysis results. .
如图2所示，从通信接口的角度来看，V2X通信包括临近通信第5接口(prose communication 5，PC5)通信和Uu接口通信，即有些V2X业务通过Uu接口与V2X应用服务器进行通信，而有些V2X业务通过PC5接口直接进行UE之间的通信。Uu接口通信和PC5接口通信使用不同的频段，Uu接口通信和PC5接口通信(也称PC5通信)可以同时进行。从通信对象的角度来说，V2X通信包括车到车(vehicle to vehicle，V2V)、车到行人(vehicle to pedestrian，V2P)、行人到车(pedestrianto vehicle，P2V)、行人到行人(pedestrian to pedestrian，P2P)、车到路边单元(Vehicle to RSU，V2(RSU))等多种通信。这里行人指的是行人的用户设备，例如手机。举例来说，V2P是指车到行人的用户设备。As shown in Figure 2, from the perspective of communication interface, V2X communication includes communication with the fifth interface of proximity communication (prose communication 5, PC5) and communication with the Uu interface, that is, some V2X services communicate with the V2X application server through the Uu interface, while Some V2X services communicate directly between UEs through the PC5 interface. Uu interface communication and PC5 interface communication use different frequency bands, and Uu interface communication and PC5 interface communication (also called PC5 communication) can be performed at the same time. From the perspective of communication objects, V2X communication includes vehicle-to-vehicle (V2V), vehicle-to-pedestrian (V2P), pedestrian-to-vehicle (P2V), and pedestrian-to-pedestrian (pedestrian to pedestrian). , P2P), vehicle to roadside unit (Vehicle to RSU, V2 (RSU)) and other communications.

从通信类型来看，V2X通信包括单播(unicast)，组播(groupcast)，广播(broadcast)。另外，V2X业务存在多种不同的业务类型，每种业务类型对应不同的应用场景和QoS要求。In terms of communication types, V2X communication includes unicast (unicast), multicast (groupcast), and broadcast (broadcast). In addition, there are many different service types for V2X services, and each service type corresponds to different application scenarios and QoS requirements.
目前，终端设备通过组播或者广播进行V2X通信时，终端设备需要时刻监听来自其他设备的V2X消息，同时通过组播或广播的方式发送其应用层产生的任意V2X消息。本申请中，V2X消息可以是P2V消息，也可以是V2P消息，还可以是其他消息。换句话说，终端设备一直处于既发送V2X消息又接收V2X消息的模式，即发送和接收模式。可以理解，当前采用的V2X通信方案中，终端设备一直处于发送和接收模式，未考虑通过组播/广播方式进行V2X通信时的节能问题。本申请提供的技术方案，考虑了通过组播/广播方式进行V2X通信时的节能问题，通过灵活地设置传输V2X消息的模式，可以避免不必要的V2X消息传输导致的电能损耗。本申请提供的技术方案主要用于解决终端设备通过组播/广播方式与其他终端设备进行V2X通信时的节能问题，终端设备可基于发送自身周边的环境信息，采用合理的传输V2X消息的模式，以实现PC5接口的通信节能。At present, when a terminal device performs V2X communication through multicast or broadcast, the terminal device needs to monitor V2X messages from other devices at all times, and at the same time send any V2X message generated by its application layer through multicast or broadcast. In this application, the V2X message may be a P2V message, a V2P message, or other messages. In other words, the terminal device is always in a mode of both sending and receiving V2X messages, that is, sending and receiving mode. It can be understood that, in the currently adopted V2X communication solution, the terminal device is always in the sending and receiving mode, and the energy saving problem when performing V2X communication through multicast/broadcast is not considered. The technical solution provided by this application takes into account the energy saving problem when V2X communication is performed through multicast/broadcast, and by flexibly setting the mode for transmitting V2X messages, power consumption caused by unnecessary V2X message transmission can be avoided. The technical solutions provided in this application are mainly used to solve the energy saving problem when terminal equipment communicates with other terminal equipment through multicast/broadcast. In order to realize the communication energy saving of PC5 interface.
本申请提供的技术方案的主要原理如下：在足够安全的原则下，终端设备(例如手机)尽量少发送少接收V2X消息。终端设备可针对特定的V2X应用，基于周边的环境等设置PC5收发模式(即通过PC5接口传输V2X消息的模式)，并且调整广播V2X消息的范围(range)，从而降低发送功率。The main principles of the technical solutions provided by the present application are as follows: under the principle of sufficient security, terminal devices (such as mobile phones) try to send and receive less V2X messages as little as possible. The terminal device can set the PC5 transceiver mode (that is, the mode of transmitting V2X messages through the PC5 interface) based on the surrounding environment and other specific V2X applications, and adjust the range of broadcast V2X messages, thereby reducing the transmission power.
下面结合一个应用场景的示例进一步介绍本申请提供的技术方案的主要原理。The main principles of the technical solutions provided by the present application are further described below in combination with an example of an application scenario.

In Fig. 3, 301 denotes a terminal device (such as a mobile phone) in a congested area and a dangerous area such as a road environment. The terminal device 301 both sends and receives V2X messages, that is, performs PC5 transceiver communication; 302 denotes a non-congested area and away from the road Terminal equipment in a relatively safe area such as the environment, terminal equipment 302 only sends V2X messages or only receives V2X messages, that is, executes PC5 to send or receive communications; 303 represents terminal equipment in a safe area without traffic environment, and terminal equipment 303 neither receives V2X The messages also do not send V2X messages, i.e. do not perform PC5 communication. It can be seen from FIG. 3 that terminal devices (such as mobile phones) in different environments can adopt different transceiver modes under the condition of ensuring security.

When the first terminal device adopts the no-send-no-receive mode, it neither sends V2X messages nor receives V2X messages from other terminal devices. The mode of only sending and not receiving refers to the mode of sending V2X messages but not receiving V2X messages. When the first terminal device adopts the mode of only sending and not receiving, it sends V2X messages, but does not receive V2X messages from other terminal devices. The mode of receiving only and not sending refers to the mode of receiving V2X messages without sending V2X messages.

在一些可能的实现方式中，第一终端设备还可以考虑地理位置信息来确定待采用的收发模式。也就是说，第一终端设备可以将其当前所处的位置和周边环境信息作为辅助信息来确定待采用的收发模式。例如，若第一终端设备E处于十字路口，则属于高危地区，确定待采用发送和接收模式，即既发送也接收V2X消息；若第一终端设备处于建筑物内部或远离马路的地方，则确定待采用不发送不接收模式，即不发送不接收V2X消息。In some possible implementation manners, the first terminal device may further consider geographic location information to determine the transmission and reception mode to be adopted. That is to say, the first terminal device may use its current location and surrounding environment information as auxiliary information to determine the sending and receiving mode to be adopted. For example, if the first terminal device E is at an intersection, it belongs to a high-risk area, and it is determined that the sending and receiving mode is to be used, that is, both sending and receiving V2X messages; if the first terminal device is located inside a building or away from the road, it is determined The mode of not sending and not receiving is to be adopted, that is, neither sending nor receiving V2X messages.
在一些可能的实现方式中，第一终端设备选择上述哪种节能的收发模式，可以是基于第一终端设备的特性实现。也就是说，不同类型的终端设备可采用不同的收发模式。例如，对于车辆类型的终端设备，无需节电，则可以始终处于既发送又接收的模式。In some possible implementation manners, which of the foregoing energy-saving transceiver modes the first terminal device selects may be implemented based on the characteristics of the first terminal device. That is to say, different types of terminal devices can adopt different transceiving modes. For example, vehicle type end devices can always be in both transmit and receive mode without power saving.

上述第二收发模式为上述不发送不接收模式，或上述只发送不接收模式，或上述只接收不发送模式，或上述低频率发送和接收模式，或上述高频率发送和接收模式。可选的，在当前时刻达到第一收发模式的失效时刻时，第一终端设备确定第一收发模式失效。可选的，第一终端设备检测到目标事件之后，确定第一收发模式失效。目标事件可以是紧急传输V2X消息的事件，也可以是异常事件，还可以是其他事件，本申请不作限定。也就是说，某些事件可触发第一收发模式失效。 In a possible implementation manner, after the first transceiving mode becomes invalid, the first terminal device transmits the V2X message by using the second transceiving mode
Figure PCTCN2020108734-appb-000003
The above-mentioned second transceiving mode is the above-mentioned non-transmitting and no-receiving mode, or the above-mentioned only transmitting and no-receiving mode, or the above-mentioned only receiving and no-transmitting mode, or the above-mentioned low-frequency transmitting and receiving mode, or the above-mentioned high-frequency transmitting and receiving mode. Optionally, when the current moment reaches the failure moment of the first transceiving mode, the first terminal device determines that the first transceiving mode is invalid. Optionally, after detecting the target event, the first terminal device determines that the first transceiving mode is invalid. The target event may be an event of urgently transmitting a V2X message, an abnormal event, or other events, which are not limited in this application. That is, certain events can trigger the failure of the first transceiving mode.
可选的，在确定第一收发模式之后，上述第一终端设备确定上述第一收发模式的失效时刻。其中，失效时刻可以是时间时刻，即第一收发模式在某个时间时刻失效。例如每个收发模式的有效时长为10秒、30秒、1分钟、五分钟等。举例来说，第一终端设备在采用第一收发模式传输V2X消息的时长达到第一收发模式的有效时长(即达到第一收发模式的失效时刻)时，第一收发模式失效。可选的，第一收发模式的有效时长(对应于定时器)可以基于应用实现，即不同的应用可采用不同的有效时长；也可以基于第一终端设备实现，例如不同终端设备可采用不同的有效时长；也可以由PCF配置第一收发模式的有效时长。例如，第一终端设备周围的车辆为10辆，定时器为10s；如果第一终端设备周围的车辆为20辆，定时器8s；如果第一终端设备周围车辆为50辆，定时器为5s。应理解，第一终端设备的周围环境不是一直保持不变，因此第一终端设备需要及时调整传输V2X消息的模式。在该实现方式中，第一终端设备每次确定的收发模式都有一个失效时刻，在达到当前采用的收发模式的失效时刻之后，采用重新确定的收发模式来传输V2X消息，以便于在多变的环境中及时选择合适的收发模式，在保证行人和车辆安全的同时减少电量消耗。Optionally, after determining the first transceiving mode, the first terminal device determines the failure time of the first transceiving mode. The failure moment may be a time moment, that is, the first transceiving mode is invalid at a certain time moment. For example, the effective duration of each sending and receiving mode is 10 seconds, 30 seconds, 1 minute, and five minutes. For example, when the first terminal device uses the first transceiving mode to transmit the V2X message for a duration that reaches the effective duration of the first transceiving mode (ie, reaches the failure time of the first transceiving mode), the first transceiving mode becomes invalid. Optionally, the valid duration (corresponding to the timer) of the first transceiver mode may be implemented based on applications, that is, different applications may use different valid durations; it may also be implemented based on the first terminal device, for example, different terminal devices may use different valid durations. Valid duration; the valid duration of the first transceiver mode can also be configured by the PCF. For example, if there are 10 vehicles around the first terminal device, the timer is 10s; if there are 20 vehicles around the first terminal device, the timer is 8s; if there are 50 vehicles around the first terminal device, the timer is 5s. It should be understood that the surrounding environment of the first terminal device does not always remain unchanged, so the first terminal device needs to adjust the mode of transmitting the V2X message in time. In this implementation manner, each time the transceiving mode determined by the first terminal device has an expiration time, and after reaching the expiration time of the currently used transceiving mode, the re-determined transceiving mode is used to transmit the V2X message, so as to facilitate the transmission of V2X messages in the ever-changing The appropriate sending and receiving mode can be selected in time in the environment of the mobile phone, which can reduce the power consumption while ensuring the safety of pedestrians and vehicles.

Exemplarily, the first service type is a provider service identifier (Provider service identifier, PSID), which is used to indicate the service type of the V2X service. The first service type may be understood as the V2X service being performed and/or to be performed by the first terminal device. The location information of the first terminal device can enable the second terminal device that receives the discovery request to determine whether it is necessary to return a feedback message (also called response information) to the first terminal device for the discovery request. For example, if the second terminal device If the distance from the first terminal device is greater than the distance threshold, the second terminal device does not return a feedback message to the first terminal device. Exemplarily, the first communication type is multicast or broadcast.
步骤501一种可能的实现方式如下：第一终端设备在确定当前可设置传输V2X消息的模式的情况下，通过广播或组播方式发送发现请求。本申请中，设置传输V2X消息的模式可理解为调整当前采用的传输V2X消息的模式。示例性的，第一终端设备根据V2X消息的业务类型和/或通信类型，确定是否可设置自身的收发模式，即传输V2X消息的模式。举例来说，第一终端设备的应用层触发了V2X业务，即产生了需要发送的V2X消息，V2X layer获取V2X消息的业务类型和/或通信类型，V2X layer根据V2X消息的业务类型和/或通信类型，确定是否可以灵活设置第一终端设备的收发模式。V2X消息的业务类型和/或通信类型可理解为V2X消息所属的V2X服务(service)的业务类型和/或通信类型。可选的，第一终端设备的V2X layer根据V2X消息的通信类型确定是否可以进行收发模式的灵活设置。例如，如果V2X消息的业务类型是防碰撞消息/群聊，则可以灵活设置第一终端设备的收发模式；如果V2X消息的业务类型是车队远程驾驶，则不可以灵活设置第一终端设备的收发模式。可选的，第一终端设备的V2X layer根据V2X消息的通信类型确定是否可以进行收发模式的灵活设置。举例来说，V2X消息的通信类型为多播或广播，第一终端设备的V2X layer确定可以进行收发模式的灵活设置；如果V2X消息的通信类型是单播模式通信，第一终端设备的V2X layer确定不可以进行收发模式的灵活设置。A possible implementation manner of step 501 is as follows: the first terminal device sends a discovery request by broadcasting or multicasting when it is determined that the mode of transmitting the V2X message can be currently set. In this application, setting the mode for transmitting V2X messages may be understood as adjusting the currently adopted mode for transmitting V2X messages. Exemplarily, the first terminal device determines, according to the service type and/or communication type of the V2X message, whether it can set its own sending and receiving mode, that is, the mode for transmitting the V2X message. For example, the application layer of the first terminal device triggers the V2X service, that is, a V2X message to be sent is generated, the V2X layer obtains the service type and/or communication type of the V2X message, and the V2X layer obtains the service type and/or communication type of the V2X message according to the service type and/or Communication type, to determine whether the transceiver mode of the first terminal device can be flexibly set.

Optionally, the V2X layer of the first terminal device determines, according to the communication type of the V2X message, whether flexible settings of the sending and receiving mode can be performed. For example, if the communication type of the V2X message is multicast or broadcast, the V2X layer of the first terminal device determines that flexible settings of the sending and receiving mode can be performed; if the communication type of the V2X message is unicast mode communication, the V2X layer of the first terminal device Make sure that the flexible setting of the send and receive mode is not possible.

步骤503一种可能的实现方式如下：第一终端设备根据来自上述至少一个第二终端设备的反馈信息的数量，确定上述第一收发模式；其中，至少一个第二终端设备的反馈信息的数量可以为向第一终端设备发送反馈信息的第二终端设备的数量。可以理解，在该实现方式中，假定某个第二终端设备向第一终端设备发送了不只一条反馈信息，该第一终端设备认为来自该第二终端设备的反馈信息的个数为1。举例来说，10个第二终端设备向第一终端设备一共发送了12条反馈信息，对于该第一终端设备来说，来自该10个第二终端设备的反馈信息的数量为10。可选的，上述至少一个第二终端设备的反馈信息包含各第二终端设备的位置信息；第一终端设备根据上述至少一个第二终端设备中各第二终端设备的位置信息和上述第一终端设备的位置信息，将上述至少一个第二终端设备中与上述第一终端设备之间的距离小于距离阈值的终端设备的数量，作为有效的来自上述至少一个第二终端设备的反馈信息的数量。举例来说，每个第二终端设备发送的反馈信息携带该第二终端设备的位置信息。或者，可选的，第二终端设备发送的反馈信息携带距离信息，该距离信息指示该第二终端设备与第一终端设备之间距离。可选的，第一终端设备还可以自己确定与各第二终端设备的距离(例如通过车载雷达)。上述距离阈值(例如500米、1千米、5千米等)可以是出厂时预先配置的，也可以是由运营商的PCF配置的，还可以是第一终端设备根据实际需求配置的，本申请不作限定。A possible implementation manner of step 503 is as follows: the first terminal device determines the above-mentioned first transceiving mode according to the quantity of feedback information from the at least one second terminal device; wherein, the quantity of the feedback information from the at least one second terminal device may be is the number of second terminal devices that send feedback information to the first terminal device. It can be understood that, in this implementation manner, it is assumed that a certain second terminal device sends more than one piece of feedback information to the first terminal device, and the first terminal device considers that the number of feedback information from the second terminal device is 1. For example, 10 second terminal devices send a total of 12 pieces of feedback information to the first terminal device, and for the first terminal device, the number of feedback information from the 10 second terminal devices is 10. Optionally, the feedback information of the at least one second terminal device includes location information of each second terminal device; the first terminal device is based on the location information of each second terminal device in the at least one second terminal device and the first terminal device. For the location information of the device, the number of terminal devices whose distance from the at least one second terminal device and the first terminal device is less than the distance threshold is taken as the number of valid feedback information from the at least one second terminal device. For example, the feedback information sent by each second terminal device carries the location information of the second terminal device. Or, optionally, the feedback information sent by the second terminal device carries distance information, where the distance information indicates the distance between the second terminal device and the first terminal device. Optionally, the first terminal device may also determine the distance from each second terminal device by itself (for example, by using a vehicle-mounted radar). The above distance thresholds (for example, 500 meters, 1 kilometer, 5 kilometers, etc.) can be pre-configured at the factory, or can be configured by the operator's PCF, or can be configured by the first terminal device according to actual needs. The application is not limited.

在来自上述至少一个第二终端设备的反馈信息的数量少于第二数量阈值(例如20)的情况下，上述第一终端设备确定上述第一收发模式为上述只发送不接收模式或上述只接收不发送模式，上述第二数量阈值小于上述第一数量阈值；或，In the case that the quantity of feedback information from the at least one second terminal device is less than a second quantity threshold (for example, 20), the first terminal device determines that the first transceiving mode is the above-mentioned sending-only and no-receiving mode or the above-mentioned only receiving mode In no-transmission mode, the second threshold of quantity is less than the first threshold of quantity; or,
在来自上述至少一个第二终端设备的反馈信息的数量少于第三数量阈值(例如3)的情况下，上述第一终端设备确定上述第一收发模式为上述不发送不接收模式，上述第三数量阈值小于上述第二数量阈值；或，In the case that the quantity of feedback information from the at least one second terminal device is less than a third quantity threshold (for example, 3), the first terminal device determines that the first transceiving mode is the no-transmitting-no-receiving mode, and the third The quantity threshold is less than the above-mentioned second quantity threshold; or,

Optionally, the first terminal device broadcasts the first transceiving mode and the first time information, where the first time information is used to determine the moment when the first transceiving mode becomes invalid. For example, the first time information is a timer or an effective time. The timer is used to indicate the duration of the first transceiving mode, and the effective time is used to indicate the effective cut-off time of the first transceiving mode. Exemplarily, the first terminal device may generate the first time information according to big data statistics or empirical values. Broadcasting the first transceiving mode by the first terminal device can enable the second terminal device to obtain the current transceiving mode of the first terminal device, and then reasonably adjust its own transceiving mode.
在一些实施例中，第一终端设备在确定第一收发模式之后，还可以确定上述第一收发模式的失效时刻，并且在达到上述第一收发模式的失效时刻之后，采用重新确定的第二收发模式传输V2X消息。应理解，第一终端设备的周围环境不是一直保持不变，因此第一终端设备需要及时调整传输V2X消息的模式。也就是说，第一终端设备在确定第一收发模式以及上述第一收发模式的失效时刻之后，在第一收发模式失效之前，采用第一收发模式传输V2X消息；在第一收发模式失效之后，采用重新确定的第二收发模式传输V2X消息。In some embodiments, after determining the first transceiving mode, the first terminal device may further determine the failure moment of the first transceiving mode, and after reaching the failure moment of the first transceiving mode, use the re-determined second transceiving mode mode to transmit V2X messages. It should be understood that the surrounding environment of the first terminal device does not always remain unchanged, so the first terminal device needs to adjust the mode of transmitting the V2X message in time. That is to say, after determining the first transceiving mode and the failure time of the first transceiving mode, and before the first transceiving mode becomes invalid, the first terminal device uses the first transceiving mode to transmit the V2X message; after the first transceiving mode becomes invalid, The V2X message is transmitted using the re-determined second transceiving mode.
504、第一终端设备的V2X层向上述第一终端设备的V2X应用层通知上述第一收发模式，上述V2X应用层根据上述第一收发模式进行V2X消息的收发设置。504. The V2X layer of the first terminal device notifies the V2X application layer of the first terminal device of the first sending and receiving mode, and the V2X application layer performs the sending and receiving settings of V2X messages according to the first sending and receiving mode.
举例来说，对于只接收不发送模式，V2X应用层设置为无需生成V2X消息；对于低频率发送和接收模块，V2X应用层设置较低频率，比如1HZ；对于不发送不接收模式，V2X应用层设置为无需生成V2X消息，且不将收不到V2X消息当做异常；对于只发送不接收模式，应用层设置为不将收不到V2X消息当做异常；对于高频率发送和接收模块，V2X应用层设置较高频率，比如10HZ。For example, for the mode of only receiving and not sending, the V2X application layer is set to not need to generate V2X messages; for the low-frequency sending and receiving modules, the V2X application layer is set to a lower frequency, such as 1HZ; for the mode of not sending and not receiving, the V2X application layer It is set to not need to generate V2X messages, and the failure to receive V2X messages will not be regarded as exceptions; for the mode of only sending and not receiving V2X messages, the application layer is set to not treat failure to receive V2X messages as exceptions; for high-frequency sending and receiving modules, the V2X application layer Set a higher frequency, such as 10HZ.
505、第一终端设备的V2X层向上述第一终端设备的V2X接入层通知上述第一收发模式，上述V2X接入层根据上述第一收发模式进行V2X消息的收发设置。505. The V2X layer of the first terminal device notifies the V2X access layer of the first terminal device of the first transceiving mode, and the V2X access layer performs settings for transceiving V2X messages according to the first transceiving mode.
举例来说，对于只发送不接收模式，接入层设置为不侦听PC5接口的V2X消息，或者说关闭接收V2X消息的功能；对于只接收不发送模式，AS设置为不发送PC5接口的V2X消息，或者说关闭发送V2X消息的功能；对于不发送不接收模式，AS设置为不侦听PC5接口的V2X消息，或者说关闭接收V2X消息的功能，且AS不发送PC5口的V2X消息，或者说关闭发送V2X消息的功能模块；对于低频率发送和接收模式，接入层可根据终端设备实现设置较低频率或使用网络侧(如PCF)配置的低频率，比如1HZ；对于高频率发送和接收模式，接入层可根据终端设备实现设置较高频率或使用网络侧(如PCF)配置的高 频率，比如10HZ。For example, for the mode of only sending and not receiving, the access layer is set to not listen to the V2X messages of the PC5 interface, or to disable the function of receiving V2X messages; for the mode of only receiving and not sending, the AS is set to not send the V2X of the PC5 interface. message, or disable the function of sending V2X messages; for the mode of not sending and not receiving, the AS is set to not listen to V2X messages on the PC5 interface, or the function of receiving V2X messages is disabled, and the AS does not send V2X messages on the PC5 interface, or It is said to close the function module for sending V2X messages; for low-frequency sending and receiving modes, the access layer can set a lower frequency according to the terminal device implementation or use a low frequency configured on the network side (such as PCF), such as 1HZ; For high-frequency sending and receiving In the receiving mode, the access layer can set a higher frequency according to the implementation of the terminal device or use the high frequency configured by the network side (such as PCF), such as 10HZ.
在一些实施例中，第一终端设备可仅执行步骤504和步骤505中的一个来实现对V2X消息的收发设置。也就是说，第一终端设备可执行步骤504不执行步骤505，也可以执行步骤505不执行504，还可执行步骤504和步骤505。应理解，步骤504和步骤505均是可选的，而非必要的。In some embodiments, the first terminal device may perform only one of steps 504 and 505 to implement the sending and receiving settings of the V2X message. That is to say, the first terminal device may perform step 504 but not step 505, may also perform step 505 but not perform step 504, and may also perform step 504 and step 505.

The communication interaction flow in FIG. 6 is a further refinement and improvement of the communication flow in FIG. 4 . As shown in Figure 6, the method includes:
601、第一终端设备通过广播或组播方式发送第一V2X消息。601. The first terminal device sends a first V2X message in a broadcast or multicast manner.
第一V2X消息可以为第一终端设备上正在进行的任意V2X业务所对应的V2X消息。示例性的，第一终端设备的AS层通过广播或组播方式发送第一V2X消息。The first V2X message may be a V2X message corresponding to any ongoing V2X service on the first terminal device. Exemplarily, the AS layer of the first terminal device sends the first V2X message in a broadcast or multicast manner.
可选的，第一终端设备在执行步骤601之前，可以如下操作：第一终端设备确定当前可设置传输V2X消息的模式，第一终端设备的V2X层指示第一终端设备的AS层设置传输V2X消息的模式。示例性的，第一终端设备根据V2X消息的业务类型和/或通信类型，确定是否可设置自身的收发模式，即传输V2X消息的模式。第一终端设备的V2X层指示第一终端设备的AS层设置传输V2X消息的模式的操作是可选的，因为AS层可以默认为组播/广播进行灵活设置收发模式。Optionally, before the first terminal device performs step 601, the following operations may be performed: the first terminal device determines a mode that can currently be set to transmit V2X messages, and the V2X layer of the first terminal device instructs the AS layer of the first terminal device to set the transmission V2X message The mode of the message. Exemplarily, the first terminal device determines, according to the service type and/or communication type of the V2X message, whether it can set its own sending and receiving mode, that is, the mode for transmitting the V2X message. The operation of the V2X layer of the first terminal device instructing the AS layer of the first terminal device to set the mode for transmitting V2X messages is optional, because the AS layer can flexibly set the transceiver mode for multicast/broadcast by default.
602、第二终端设备针对上述第一V2X消息发送反馈信息。602. The second terminal device sends feedback information for the first V2X message.
图6中的UE2和UE3仅作为第二终端设备的一种示例。应理解，针对第一V2X消息发送反馈信息的第二终端设备不限于两个，可以是多个，也可以是一个。由于各第二终端设备执行的操作类似，下面仅以一个第二终端设备为例进行描述。步骤602一种可能的实现方式如下：第二终端设备针对上述第一V2X消息发送混合自动重传请求(hybrid automatic repeat request，HARQ)反馈信息。UE2 and UE3 in FIG. 6 are only used as an example of the second terminal device. It should be understood that the number of second terminal devices that send feedback information for the first V2X message is not limited to two, and may be multiple or one. Since the operations performed by each second terminal device are similar, only one second terminal device is used as an example for description below. A possible implementation manner of step 602 is as follows: the second terminal device sends a hybrid automatic repeat request (hybrid automatic repeat request, HARQ) feedback information for the first V2X message.
603、第一终端设备的AS层根据接收到的反馈信息，确定第一收发模式，并根据上述第一收发模式进行V2X消息的收发设置。603. The AS layer of the first terminal device determines a first transceiving mode according to the received feedback information, and performs settings for transceiving V2X messages according to the foregoing first transceiving mode.
上述第一收发模式为不发送不接收模式，或只发送不接收模式，或只接收不发送模式，或低频率发送和接收模式，或高频率发送和接收模式。举例来说，对于只发送不接收模式，接入层设置为不侦听PC5接口的V2X消息，或者说关闭接收V2X消息的功能；对于只接收不发送模式，AS设置为不发送PC5接口的V2X消息，或者说关闭发送V2X消息的功能；对于不发送不接收模式，AS设置为不侦听PC5接口的V2X消息，或者说关闭接收V2X消息的功能，且AS不发送PC5口的V2X消息，或者说关闭发送V2X消息的功能模块；对于低频率发送和接收模式，接入层可根据终端设备实现设置较低频率或使用网络侧(如PCF) 配置的低频率，比如1HZ；对于高频率发送和接收模式，接入层可根据终端设备实现设置较高频率或使用网络侧(如PCF)配置的高频率，比如10HZ。The above-mentioned first transceiver mode is a no-transmit and no-receive mode, or a transmit-no-receive mode, or a receive-no-transmit mode, a low-frequency transmit-and-receive mode, or a high-frequency transmit-and-receive mode. For example, for the mode of only sending and not receiving, the access layer is set to not listen to the V2X messages of the PC5 interface, or to disable the function of receiving V2X messages; for the mode of only receiving and not sending, the AS is set to not send the V2X of the PC5 interface. message, or disable the function of sending V2X messages; for the mode of not sending and not receiving, the AS is set to not listen to V2X messages on the PC5 interface, or the function of receiving V2X messages is disabled, and the AS does not send V2X messages on the PC5 interface, or It is said to close the function module for sending V2X messages; for low-frequency sending and receiving modes, the access layer can set a lower frequency according to the terminal device implementation or use a low frequency configured on the network side (such as PCF), such as 1HZ; for high-frequency sending and receiving In the receiving mode, the access layer can set a higher frequency according to the implementation of the terminal device or use the high frequency configured by the network side (such as PCF), such as 10HZ.
可选的，AS层根据接收到的反馈信息为HARQ反馈信息，步骤601和步骤602可理解为第一终端设备通过HARQ机制感知周边的环境信息。Optionally, the AS layer is HARQ feedback information according to the received feedback information, and steps 601 and 602 may be understood as the first terminal device perceives the surrounding environment information through the HARQ mechanism.
步骤603一种可能的实现方式如下：第一终端设备的AS层根据接收到的反馈信息(例如HARQ反馈信息)的数量，确定上述第一收发模式；其中，AS层接收到的反馈信息的数量可以为向第一终端设备发送反馈信息的第二终端设备的数量。可以理解，在该实现方式中，假定某个第二终端设备向第一终端设备发送了不只一条反馈信息，该第一终端设备认为来自该第二终端设备的反馈信息的个数为1。可选的，第二终端设备的AS层接收到的任一反馈信息包含发送该反馈信息的第二终端设备的位置信息或者发送该反馈信息的第二终端设备与第一终端设备之间的距离信息；第一终端设备的AS层根据接收到的反馈信息，将各第二终端设备中与上述第一终端设备之间的距离小于距离阈值的终端设备的数量，作为接收到的有效的反馈信息的数量。上述距离信息由第二终端设备根据第一终端设备的位置信息和自身位置信息获取，或者根据其它方式如其车载雷达测量得到。可选的，第一终端设备还可以自己确定与各第二终端设备的距离(例如通过车载雷达)。上述距离阈值(例如500米、1千米、5千米等)可以是出厂时预先配置的，也可以是由运营商的PCF配置的，还可以是第一终端设备根据实际需求配置的。由于与第一终端设备之间的距离小于距离阈值的第二终端设备才能与第一终端设备进行可靠的V2X通信，因此这些第二终端设备发送的反馈信息才被第一终端设备的AS层认为是有效反馈信息，以便于更准确地确定收发模式。A possible implementation manner of step 603 is as follows: the AS layer of the first terminal device determines the above-mentioned first transceiving mode according to the number of received feedback information (for example, HARQ feedback information); wherein, the number of feedback information received by the AS layer It may be the number of second terminal devices that send feedback information to the first terminal device. It can be understood that, in this implementation manner, it is assumed that a certain second terminal device sends more than one piece of feedback information to the first terminal device, and the first terminal device considers that the number of feedback information from the second terminal device is 1. Optionally, any feedback information received by the AS layer of the second terminal device includes the location information of the second terminal device that sent the feedback information or the distance between the second terminal device that sent the feedback information and the first terminal device. information; according to the received feedback information, the AS layer of the first terminal device takes the number of terminal devices whose distance from each second terminal device and the above-mentioned first terminal device is less than the distance threshold as the received valid feedback information quantity. The above distance information is obtained by the second terminal device according to the position information of the first terminal device and its own position information, or obtained by other methods such as measurement by its vehicle-mounted radar. Optionally, the first terminal device may also determine the distance from each second terminal device by itself (for example, by using a vehicle-mounted radar). The above distance thresholds (eg, 500 meters, 1 kilometer, 5 kilometers, etc.) may be pre-configured at the factory, or may be configured by the operator's PCF, or may be configured by the first terminal device according to actual requirements. Because the second terminal equipment whose distance from the first terminal equipment is less than the distance threshold can perform reliable V2X communication with the first terminal equipment, the feedback information sent by these second terminal equipment is considered by the AS layer of the first terminal equipment. It is effective feedback information in order to more accurately determine the sending and receiving mode.
示例性的，第一终端设备的AS层在接收到的反馈信息的数量少于第一数量阈值(例如50)的情况下，上述第一终端设备确定上述第一收发模式为上述低频率发送和接收模式；或在来接收到的反馈信息的数量少于第二数量阈值(例如20)的情况下，上述第一终端设备确定上述第一收发模式为上述只发送不接收模式或上述只接收不发送模式，上述第二数量阈值小于上述第一数量阈值；或，在接收到的反馈信息的数量少于第三数量阈值(例如3)的情况下，上述第一终端设备确定上述第一收发模式为上述不发送不接收模式，上述第三数量阈值小于上述第二数量阈值；或，在接收到的反馈信息的数量不少于上述第一数量阈值的情况下，上述第一终端设备确定上述第一收发模式为上述高频率发送和接收模式。Exemplarily, when the number of feedback information received by the AS layer of the first terminal device is less than a first number threshold (for example, 50), the first terminal device determines that the first transceiving mode is the low-frequency sending and receiving mode; or when the quantity of received feedback information is less than a second quantity threshold (for example, 20), the first terminal device determines that the first transceiving mode is the above-mentioned sending-only and no-receiving mode or the above-mentioned receiving-only and no-receiving mode. sending mode, the second quantity threshold is less than the first quantity threshold; or, in the case where the quantity of the received feedback information is less than the third quantity threshold (for example, 3), the first terminal device determines the first sending and receiving mode For the above-mentioned non-transmitting and non-receiving mode, the above-mentioned third quantity threshold is less than the above-mentioned second quantity threshold; or, in the case where the quantity of the received feedback information is not less than the above-mentioned first quantity threshold, the above-mentioned first terminal device determines that the above-mentioned first A transceiving mode is the above-mentioned high frequency transmitting and receiving mode.
604、第一终端设备的AS层向上述第一终端设备的V2X应用层通知上述第一收发模式，上述V2X应用层根据上述第一收发模式进行V2X消息的收发设置。604. The AS layer of the first terminal device notifies the V2X application layer of the first terminal device of the first transceiving mode, and the V2X application layer performs settings for transceiving V2X messages according to the first transceiving mode.
可选的，上述V2X接入层可以直接向上述第一终端设备的V2X应用层通知上述第一收发模式，或者，上述V2X接入层可以通过V2X层间接向上述第一终端设备的V2X应用层通知上述第一收发模式。举例来说，对于只接收不发送模式，V2X应用层设置为无需生成V2X消息；对于低频率发送和接收模块，V2X应用层设置较低频率，比如1HZ；对于不发送不接收模式，V2X应用层设置为无需生成V2X消息，且不将收不到V2X消息当做异常；对于只发送不接收模式，应用层设置为不将收不到V2X消息当做异常；对于高频率发送和接收模块，V2X应用层设置较高频率，比如10HZ。Optionally, the V2X access layer may directly notify the V2X application layer of the first terminal device of the first transceiver mode, or the V2X access layer may indirectly notify the V2X application layer of the first terminal device through the V2X layer. The above-mentioned first transmission and reception mode is notified. For example, for the mode of only receiving and not sending, the V2X application layer is set to not need to generate V2X messages; for the low-frequency sending and receiving modules, the V2X application layer is set to a lower frequency, such as 1HZ; for the mode of not sending and not receiving, the V2X application layer It is set to not need to generate V2X messages, and the failure to receive V2X messages will not be regarded as exceptions; for the mode of only sending and not receiving V2X messages, the application layer is set to not treat failure to receive V2X messages as exceptions; for high-frequency sending and receiving modules, the V2X application layer Set a higher frequency, such as 10HZ.
应理解，第一终端设备根据上述第一收发模式进行V2X消息的收发设置之后，采用上 述第一收发模式传输V2X消息。It should be understood that after the first terminal device performs the sending and receiving settings of the V2X message according to the first sending and receiving mode, the first terminal device uses the first sending and receiving mode to transmit the V2X message.
例如，对于只接收不发送模式，V2X应用层无需生成V2X消息；或者，对于低频率发送和接收模式，V2X应用层据此降低V2X消息的发送/接收频率。For example, for the receive-only-not-send mode, the V2X application layer does not need to generate V2X messages; or, for the low-frequency sending and receiving mode, the V2X application layer reduces the sending/receiving frequency of V2X messages accordingly.
本申请实施例中，第一终端设备感知周边的信息，并据此确定采用更加节能的第一收发模式传输V2X消息，既能保证行人和车辆的交通安全又能节能。In this embodiment of the present application, the first terminal device senses surrounding information, and determines accordingly to transmit the V2X message by using the more energy-saving first transceiver mode, which can not only ensure the traffic safety of pedestrians and vehicles but also save energy.
