Abstract

Provided are a resource allocation method and a related equipment. The resource allocation method comprises: upon creation of a first CAM data packet by a vehicle user terminal equipment (V-UE), if a target resource capable of transmitting the first CAM data packet has been allocated by a base station, transmitting, by the V-UE, the first CAM data packet directly on the target resource so as to effectively guarantee a data volume for communication between the base station and the V-UE; and if the target resource is not allocated by the base station, creating, by the V-UE, a BSR-V to enable the base station to allocate the target resource according to a creation interval of the first CAM data packet, thereby allowing the base station to allocate the target resource according to the creation interval of the first CAM data packet even when a resource previously allocated by the base station is not applicable due to changes in a driving state of a vehicle and a size of the CAM data packet.

Description

一种资源配置方法以及相关设备Resource configuration method and related equipment 技术领域Technical field

本发明涉及V2V通信领域，尤其涉及的是一种资源配置方法以及相关设备。The present invention relates to the field of V2V communication, and in particular, to a resource configuration method and related equipment.

背景技术Background technique

现有技术中，为提升交通安全，则使得智能交通系统(Intelligent Transportation System,ITS)、车联网等概念及相关研究成为全球关注的热点。V2V(车辆与车辆，Vehicle to Vehicle)通信是ITS及车联网研究中的一项重要内容，其可以提供并支持与道路交通安全方面相关的应用和业务传输，从而被广泛认为是提高车辆行驶安全、减少交通事故的关键技术。V2V通信可以通过车辆与车辆之的无线通信进行信息交互，使得车辆能够及时获取路况信息或接收与车辆行驶安全相关的信息(后文统称为“车辆安全信息”)服务，辅助车辆驾驶员对危险进行预判并进行相应操作，以尽可能避免事故发生。具体来说，车辆可以通过V2V通信，将车速、行驶方向、所处位置、加速或减速、是否刹车等自身的行驶状态信息通过无线广播的方式发送给周围的车辆；周围其他车辆的通过接收该类消息(如与其他车辆的距离、附近是否有其他车辆急刹车、是否有故障车辆等)，对危险情况作出预判，并向驾驶员及时发出告警，辅助驾驶员进行采取相应的预防措施，尽可能避免事故的发生。In the prior art, in order to improve traffic safety, concepts such as Intelligent Transportation System (ITS) and vehicle networking and related research have become global hotspots. V2V (Vehicle to Vehicle) communication is an important part of ITS and car networking research. It can provide and support applications and service transmission related to road traffic safety, which is widely considered to improve vehicle driving safety. Key technologies to reduce traffic accidents. V2V communication can exchange information through wireless communication between the vehicle and the vehicle, so that the vehicle can acquire road condition information in time or receive information related to vehicle driving safety (hereinafter referred to as "vehicle safety information") to assist the vehicle driver in danger. Pre-judgment and corresponding operations to avoid accidents as much as possible. Specifically, the vehicle can transmit its own driving state information such as the vehicle speed, the traveling direction, the position, the acceleration or deceleration, and whether the brake is transmitted to the surrounding vehicles through V2V communication; the other vehicles in the vicinity receive the Class messages (such as distance from other vehicles, whether there are other vehicles in the vicinity, whether there is a faulty vehicle, etc.), pre-judging the dangerous situation, and issuing an alarm to the driver in time to assist the driver to take appropriate preventive measures. Avoid accidents as much as possible.

为了保证车辆安全行驶，车辆与车辆之间需要通过车辆动态控制(Vehicle Dynamic Control，VDC)接口交互协作感知消息(Cooperative Aware Message，CAM)的安全类消息；该CAM消息中包含V2V通信中车辆交通安全方面的消息，如车速、行驶方向、经纬度(所处位置)、加速度(加减速)、等信息。In order to ensure the safe driving of the vehicle, a safety message of a Cooperative Aware Message (CAM) is required between the vehicle and the vehicle through a Vehicle Dynamic Control (VDC) interface; the CAM message includes the vehicle traffic in the V2V communication. Safety information such as speed, direction of travel, latitude and longitude (position), acceleration (acceleration and deceleration), and other information.

为支持包括安全类消息在内的V2V车载通信业务的无线传输，在无线资源分配方面，均采用以CSMA(载波侦听多路访问，Carrier Sense Multiple Access)技术为核心的、基于用户自由竞争的资源分配方式。作为一种分布式的资源分配方式，尽管这种基于用户自由竞争的资源分配技术具有实现简单的优点，但由于其缺乏多用户之间的有效协调，不同用户可能在同一时间、抢占相同的信道资源发送各自的数据，导致多个用户发送的数据彼此相互碰撞、产 生多用户间的通信干扰，严重影响通信性能，造成用户的数据无法正常收发。特别对于CAM这类承载车辆安全消息的业务来说，这种基于自由竞争的资源分配方式，将在很大程度上导致车辆间无法进行有效的安全信息交互，从而增加车辆危险情况发生的概率。In order to support the wireless transmission of V2V in-vehicle communication services including security messages, in terms of radio resource allocation, CSMA (Carrier Sense Multiple Access) technology is adopted as the core, based on user free competition. The way resources are allocated. As a distributed resource allocation method, although this resource allocation technology based on user free competition has the advantage of simple implementation, due to its lack of effective coordination among multiple users, different users may preempt the same channel at the same time. Resources send their own data, causing data sent by multiple users to collide with each other The communication interference between multiple users seriously affects the communication performance, and the data of the user cannot be sent and received normally.

具体实施方式detailed description

为使本发明实施例的目的、技术方案和优点更加清楚，下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。The technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. It is a partial embodiment of the invention, and not all of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.

首先对实现本发明所示的资源配置方法的应用场景进行详细说明，具体可参见图1所示；The application scenario of the resource configuration method shown in the present invention is described in detail. For details, refer to FIG. 1;

图1中，LTE蜂窝上行链路用于实现V-UE与基站之间的上行无线数据传 输，LTE蜂窝下行链路则用于实现基站与V-UE之间的下行无线数据传输，V-UE和V-UE之间则利用V2V通信链路，实现协作感知消息CAM数据包的无线传输。此外，不仅限于V-UE1，V-UE2和V-UE3同样可以与基站建立LTE上行/下行蜂窝链路，同时利用V2V通信链路向其他车辆发送包含有协作感知消息(Cooperative Aware Message，CAM)的安全类消息的CAM数据包。In Figure 1, the LTE cellular uplink is used to implement uplink wireless data transmission between the V-UE and the base station. The LTE cellular downlink is used to implement downlink wireless data transmission between the base station and the V-UE, and the V-UE and the V-UE use the V2V communication link to implement wireless transmission of the cooperative sensing message CAM data packet. . In addition, not only V-UE1, V-UE2 and V-UE3 can also establish an LTE uplink/downlink cellular link with the base station, and simultaneously transmit a Cooperative Aware Message (CAM) to other vehicles by using the V2V communication link. CAM packets for security class messages.

以下首先对所述CAM数据包进行具体说明：The CAM packet is first described in detail below:

所述CAM数据包是否产生取决于是否满足一定的触发条件，当满足CAM数据包的触发条件时，即会产生一个用于V2V通信的CAM数据包；Whether the CAM data packet is generated depends on whether a certain trigger condition is met, and when the trigger condition of the CAM data packet is met, a CAM data packet for V2V communication is generated;

具体的，从上一个CAM数据包产生开始，车辆用户终端设备V-UE判断新的CAM数据包产生至少需要满足以下触发条件之一：Specifically, starting from the generation of the last CAM data packet, the vehicle user terminal device V-UE determines that the new CAM data packet generation needs to meet at least one of the following trigger conditions:

触发条件1：当前车辆行驶方向与上一个CAM数据包产生时的行驶方向(以正北方向为基准)的角度变化超过4°；Trigger condition 1: the angle of change of the current vehicle travel direction and the travel direction (based on the north direction) of the previous CAM packet generation exceeds 4°;

触发条件2：当前车辆的位置与上一个CAM数据包产生时的位置位移超过4m；Trigger condition 2: the position of the current vehicle and the position displacement of the previous CAM data packet generated exceed 4m;

触发条件3：当前车辆的行驶速度与上一个CAM数据包产生时的行驶速度的变化超过0.5m/s。Trigger Condition 3: The change in the current vehicle's travel speed and the travel speed at the time of the last CAM packet generation exceeds 0.5 m/s.

所述V-UE将每隔固定周期对CAM数据包触发条件检测一次，并据此确定是否产生新的CAM数据包。The V-UE will detect the CAM packet trigger condition once every fixed period and determine whether to generate a new CAM packet accordingly.

本发明实施例对所述固定周期的大小不做限定，为更好的理解本发明的技术方案，则本发明实施例以所述固定周期可为100ms为例进行示例说明；The embodiment of the present invention does not limit the size of the fixed period. For a better understanding of the technical solution of the present invention, the embodiment of the present invention is exemplified by taking the fixed period as 100 ms as an example.

此外，CAM数据包产生的间隔不低于100ms并且不高于1000ms。In addition, the CAM packet is generated at intervals of not less than 100 ms and not higher than 1000 ms.

可见，CAM数据包触发与否与车辆的速度、加速度、行驶方向等车辆行驶动态密切相关；It can be seen that the triggering of the CAM data packet is closely related to the driving dynamics of the vehicle such as the speed, acceleration and driving direction of the vehicle;

所述CAM数据包生成间隔会随着车辆行驶的状态变化而发生改变，这里将先后产生的两个相邻CAM数据包间的时间间隔称为CAM数据包的“生成间隔”，可以看到车辆的速度、加速度、行驶方向等行驶状态也将是影响CAM数据包生成间隔的重要因素。The CAM packet generation interval changes according to the state of the vehicle traveling. Here, the time interval between two adjacent CAM data packets generated successively is referred to as the “generation interval” of the CAM data packet, and the vehicle can be seen. Driving conditions such as speed, acceleration, and direction of travel will also be important factors influencing the CAM packet generation interval.

根据上述对所述CAM数据包触发的说明，所述V-UE所产生的CAM数据包，其生成间隔的可能取值为100ms、200ms、300ms、……、1000ms， 且具体生成间隔与车辆行驶状态有关。According to the above description of the triggering of the CAM data packet, the possible intervals of the generation interval of the CAM data packet generated by the V-UE are 100 ms, 200 ms, 300 ms, ..., 1000 ms, And the specific generation interval is related to the driving state of the vehicle.

经进一步分析，当车辆处于一定的行驶速度、加速度或转向盘角速度范围时，CAM数据包的到达将呈现相应的周期特性。After further analysis, when the vehicle is in a certain range of driving speed, acceleration or steering wheel angular velocity, the arrival of the CAM data packet will exhibit corresponding periodic characteristics.

基于上述说明，所述CAM数据包生成间隔会随着车辆行驶的状态变化而发生改变，也就是说，车辆的CAM消息等价于一系列具不同数据包生成间隔的周期性业务。Based on the above description, the CAM packet generation interval changes as the state of the vehicle travels, that is, the CAM message of the vehicle is equivalent to a series of periodic services having different packet generation intervals.

本实施例提供一种能够实现车辆用户终端设备V-UE与基站之间数据通信的资源配置方法；The embodiment provides a resource configuration method capable of realizing data communication between a vehicle user terminal device V-UE and a base station;

以下结合图2所示对本实施例所提供的所述资源配置方法进行详细说明；The resource configuration method provided in this embodiment is described in detail below with reference to FIG. 2;

201、车辆用户终端设备V-UE确定第一协作感知消息CAM数据包的生成间隔；201. The vehicle user terminal device V-UE determines a generation interval of the first cooperative sensing message CAM data packet.

The current driving state satisfies the trigger condition, and the V-UE generates the first CAM data packet;

具体的，所述第一CAM数据包的生成间隔为所述第一CAM数据包生成时刻与第二CAM数据包的生成时刻之间的差值，所述第一CAM数据包和所述第二CAM数据包相邻，且所述第二CAM数据包早于所述第一CAM数据包生成；Specifically, the generating interval of the first CAM data packet is a difference between the first CAM data packet generating time and the second CAM data packet generating time, the first CAM data packet and the second CAM data packets are adjacent, and the second CAM data packet is generated earlier than the first CAM data packet;

更具体的，所述V-UE确定车辆当前的行驶状态满足所述触发条件时，则所述V-UE在RLC层收到上层递交下来的所述第一CAM数据包，并确定所述第一CAM数据包生成时刻与第二CAM数据包的生成时刻之间的差值，进而将该差值确定为所述第一CAM数据包的生成间隔。More specifically, when the V-UE determines that the current driving state of the vehicle meets the trigger condition, the V-UE receives the first CAM data packet submitted by the upper layer at the RLC layer, and determines the first a difference between a CAM packet generation time and a generation time of the second CAM packet, and further determining the difference as a generation interval of the first CAM packet.

202、所述V-UE根据所述第一CAM数据包的生成间隔确定基站是否已配置能够传输所述第一CAM数据包的目标资源，若否，则进行步骤203，若是，则进行步骤205；202. The V-UE determines, according to the interval for generating the first CAM data packet, whether the base station has configured the target resource capable of transmitting the first CAM data packet. If not, proceed to step 203, and if yes, proceed to step 205. ;

本实施例对所述基站已配置的能够传输所述第一CAM数据包的目标资源不做限定，只要所述V-UE根据所述基站已配置的所述目标资源能够将所述第一CAM数据包发送给所述基站即可。 In this embodiment, the target resource that the base station has configured to transmit the first CAM data packet is not limited, as long as the V-UE can perform the first CAM according to the target resource that the base station has configured. The data packet can be sent to the base station.

203、所述V-UE根据所述第一CAM数据包的生成间隔生成车辆缓存状态报告；203. The V-UE generates a vehicle cache status report according to the generation interval of the first CAM data packet.

本实施例中，所述车辆缓存状态报告(Buffer State Repot of V-UE，BSR-V)为所述V-UE根据所述第一CAM数据包的生成间隔针对V2V通信中CAM业务传输所生成的；In this embodiment, the Buffer State Repot of V-UE (BSR-V) is generated by the V-UE for the CAM service transmission in the V2V communication according to the generation interval of the first CAM data packet. of;

所述V-UE能够通过所述BSR-V请求基站根据所述BSR-V配置能够传输所述第一CAM数据包的所述目标资源。The V-UE can request the base station to transmit the target resource of the first CAM data packet according to the BSR-V configuration by using the BSR-V.

本实施例对所述BSR-V的具体配置方式和具体格式不做限定，只要所述基站能够根据所述BSR-V配置用于传输所述第一CAM数据包的所述目标资源即可。The specific configuration mode and the specific format of the BSR-V are not limited in this embodiment, as long as the base station can configure the target resource for transmitting the first CAM data packet according to the BSR-V.

204、所述V-UE将所述BSR-V发送给所述基站；204. The V-UE sends the BSR-V to the base station.

其中，所述BSR-V用于请求所述基站配置所述目标资源，以使所述基站根据所述BSR-V配置所述目标资源；The BSR-V is configured to request the base station to configure the target resource, so that the base station configures the target resource according to the BSR-V.

205、所述V-UE在所述目标资源上传输所述第一CAM数据包。205. The V-UE transmits the first CAM data packet on the target resource.

由上所示可知，本实施例中用于所述V-UE传输所述第一CAM数据包的目标资源有两种：It can be seen from the above that there are two types of target resources for the V-UE to transmit the first CAM data packet in this embodiment:

一种是所述基站预先配置的，且所述V-UE已确定基站预先配置的资源能够用于传输所述第一CAM数据包；One is that the base station is pre-configured, and the V-UE has determined that a resource pre-configured by the base station can be used to transmit the first CAM data packet;

另一种是所述V-UE通过所述BSR-V触发所述基站配置的；Another type is that the V-UE triggers the configuration of the base station by using the BSR-V;

若所述基站并未预先配置资源或已配置的资源不能用于传输所述第一 CAM数据包时，所述V-UE即可通过所述BSR-V触发基站配置能够传输所述第一CAM数据包的目标资源；If the base station does not pre-configure resources or configured resources cannot be used to transmit the first When the CAM packet is used, the V-UE may trigger the base station to configure, by using the BSR-V, a target resource capable of transmitting the first CAM data packet;

具体的，若车辆的所述车辆行驶状态发生改变以使所述CAM数据包到达的周期发生改变，或，所述CAM数据包的大小发生改变，例如由高频的CAM数据包变为低频的CAM数据包，或者由低频的CAM数据包变为高频的CAM数据包，则会使得所述基站预先配置的资源不能够用于传输所述第一CAM数据包；Specifically, if the running state of the vehicle of the vehicle changes to change the period in which the CAM data packet arrives, or the size of the CAM data packet changes, for example, the high frequency CAM data packet changes to a low frequency. The CAM data packet, or the CAM data packet changed from the low frequency CAM data packet to the high frequency CAM data packet, may cause the resource configured by the base station to be unavailable for transmitting the first CAM data packet;

所述V-UE在确定所述基站根据所述BSR-V所配置的所述目标资源后，则所述V-UE在所述目标资源上传输所述第一CAM数据包，以使所述基站在所述目标资源上接收所述第一CAM数据包。After determining, by the V-UE, the target resource configured by the base station according to the BSR-V, the V-UE transmits the first CAM data packet on the target resource, so that the The base station receives the first CAM data packet on the target resource.

可见，采用本实施例所示的优势在于，若所述基站预先已经配置了能够传输所述第一CAM数据包的目标资源，则所述V-UE即可直接在所述基站已配置的所述目标资源上传输所述第一CAM数据包，从而使得即便所述CAM数据包频繁的生成，且位于车辆比较密集的环境下，只要车辆当前的行驶状态不发生改变，以使所述CAM数据包在一定车辆行驶状态下呈现周期性到达的状态，则所述V-UE能够直接在所述基站已配置的所述目标资源上传输所述第一CAM数据包，无需基站反复为CAM数据包分配资源，从而有效的保障了基站与V-UE之间通信的数据量的容量，有效的支持V2V通信中车辆间的CAM消息传输；It can be seen that the advantage shown in this embodiment is that if the base station has previously configured the target resource capable of transmitting the first CAM data packet, the V-UE may directly be in the configured location of the base station. Transmitting the first CAM data packet on the target resource, so that even if the CAM data packet is frequently generated and located in a relatively dense environment of the vehicle, as long as the current driving state of the vehicle does not change, so that the CAM data is The V-UE can directly transmit the first CAM data packet on the target resource that the base station has configured, without the base station repeating the CAM data packet. Allocating resources, thereby effectively protecting the capacity of the data volume between the base station and the V-UE, and effectively supporting the CAM message transmission between the vehicles in the V2V communication;

所述基站若接收到所述V-UE发送的所述BSR-V，则所述基站即可确定所述基站未配置能够接收所述第一CAM数据包的目标资源；If the base station receives the BSR-V sent by the V-UE, the base station may determine that the base station is not configured to receive the target resource of the first CAM data packet;

其中，所述BSR-V由所述V-UE根据所述第一CAM数据包的生成间隔生成，所述第一CAM数据包的生成间隔为所述第一CAM数据包生成时刻与第二CAM数据包的生成时刻之间的差值，所述第一CAM数据包和所述第二CAM数据包相邻，且所述第二CAM数据包早于所述第一CAM数据包生成；The BSR-V is generated by the V-UE according to the generation interval of the first CAM data packet, and the first CAM data packet generation interval is the first CAM data packet generation time and the second CAM. a difference between the generation times of the data packets, the first CAM data packet and the second CAM data packet are adjacent, and the second CAM data packet is generated earlier than the first CAM data packet;

303、所述基站根据所述BSR-V为所述V-UE配置所述目标资源；303. The base station configures the target resource for the V-UE according to the BSR-V.

本实施例对所述基站具体如何根据所述BSR-V为所述V-UE配置所述目标资源不做限定，只要所述基站根据所述BSR-V所配置的所述目标资源能够用来传输所述第一CAM数据包即可。The present embodiment is not limited to how the base station specifically configures the target resource according to the BSR-V for the V-UE, as long as the target resource configured by the base station according to the BSR-V can be used. The first CAM data packet can be transmitted.

304、所述基站在所述目标资源上接收所述第一CAM数据包。304. The base station receives the first CAM data packet on the target resource.

由上所示可知，本实施例中用于所述基站接收所述第一CAM数据包的目标资源有两种：As shown in the above, there are two types of target resources used by the base station to receive the first CAM data packet in this embodiment:

一种是如步骤301所示的所述基站预先配置的，则所述基站在预先配置的目标资源上接收所述第一CAM数据包；If the base station is pre-configured as shown in step 301, the base station receives the first CAM data packet on a pre-configured target resource;

另一种是所述V-UE通过所述BSR-V触发所述基站配置的(如步骤302至步骤304所示)；The other is that the V-UE triggers the configuration of the base station by using the BSR-V (as shown in step 302 to step 304);

可见，采用本实施例所示的优势在于，若所述基站已经配置了能够传输所述第一CAM数据包的目标资源，则所述基站直接在所述基站已配置的所述目标资源上接收所述第一CAM数据包，从而使得即便所述CAM数据包频繁的生成，且位于车辆比较密集的环境下，所述V-UE能够直接在所述基站已配置的所述目标资源上传输所述第一CAM数据包，无需基站反复为CAM数据包分配资源，从而有效的保障了基站与V-UE之间通信的数据量的容量，有效的支持V2V通信中车辆间的CAM消息传输，若所述基站未配置所述目标资源或所述基站已配置的资源不能够用于传输所述第一CAM数据包，则所述V-UE能够生成用于触发所述基站配置用于传输所述第一CAM数据包的所述BSR-V，基站即可根据所述BSR-V配置所述目标资源，从而使得即便车辆的行驶状态发生变化以使基站预先配置的资源不再适用，或者所述基站未配置目标资源时，所述基站能够根据所述BSR-V配置用于传输所述第一CAM数据包的目标资源，从而有效的保障了V2V通信中车辆间的CAM消息传输。It can be seen that the advantage shown in this embodiment is that if the base station has configured a target resource capable of transmitting the first CAM data packet, the base station directly receives on the target resource that the base station has configured. The first CAM data packet, such that the V-UE can directly transmit on the target resource that the base station has configured, even if the CAM data packet is frequently generated and located in a relatively dense environment of the vehicle The first CAM data packet does not require the base station to repeatedly allocate resources for the CAM data packet, thereby effectively ensuring the capacity of the data volume between the base station and the V-UE, and effectively supporting the CAM message transmission between the vehicles in the V2V communication. If the base station is not configured with the target resource or the resource configured by the base station cannot be used to transmit the first CAM data packet, the V-UE can generate a trigger for the base station to be configured to transmit the The BSR-V of the first CAM data packet, the base station may configure the target resource according to the BSR-V, so that even if the driving state of the vehicle changes so that the resources pre-configured by the base station are no longer applicable, Or, when the base station is not configured with the target resource, the base station is configured to transmit the target resource of the first CAM data packet according to the BSR-V, thereby effectively securing the CAM message transmission between the vehicles in the V2V communication.

以下结合附图4所示对所述资源配置方法的具体实现方式进行详细说明，其中，图4所示为当第一CAM数据包为高频的CAM数据包，且所述第一CAM数据包的生成间隔与第二CAM数据包的生成间隔相等时是如何实现所述资源配置方法的进行详细说明；The specific implementation manner of the resource configuration method is described in detail below with reference to FIG. 4, wherein FIG. 4 shows a first CAM data packet when the first CAM data packet is a high frequency CAM data packet. A detailed description of how the resource configuration method is implemented when the generation interval is equal to the generation interval of the second CAM packet;

401、基站生成预置对应关系； 401. The base station generates a preset correspondence relationship.

本实施例中，所述预置对应关系包括第一CAM数据包的生成间隔与半静态调度SPS资源周期的对应关系，且所述第一CAM数据包的生成间隔等于通过所述预置对应关系与所述第一CAM数据包的生成间隔对应的SPS资源的周期；In this embodiment, the preset correspondence relationship includes a correspondence between a generation interval of the first CAM data packet and a semi-persistent scheduling SPS resource period, and the generation interval of the first CAM data packet is equal to the preset correspondence relationship. a period of the SPS resource corresponding to the generation interval of the first CAM data packet;

其中，所述第一CAM数据包的具体说明请详见上述实施例所示，具体在本实施例中不做赘述。For a detailed description of the first CAM data packet, please refer to the foregoing embodiment, which is not specifically described in this embodiment.

为更好的理解本发明实施例，以下首先对通过所述预置对应关系与所述第一CAM数据包对应的SPS(Semi-persistent Scheduling，半静态调度)资源进行说明；For a better understanding of the embodiment of the present invention, the SPS (Semi-persistent Scheduling) resource corresponding to the first CAM data packet is first described in the following;

所述SPS用来支持VoIP(Voice over IP)等具有数据包周期性到达特性的业务。SPS利用话音数据包周期性到达、且数据包大小固定的特点，一次授权、周期使用，使得UE每隔固定的周期在相同的时频资源位置上进行业务数据的发送或接收，从而可以有效节省LTE系统用于调度的PUCCH、PDCCH资源，达到降低系统调度开销的目的。The SPS is used to support services such as VoIP (Voice over IP) with periodic arrival characteristics of data packets. The SPS uses the characteristics that the voice data packets arrive periodically and the data packet size is fixed, and the one-time authorization and periodic use enable the UE to transmit or receive service data at the same time-frequency resource location every fixed period, thereby effectively saving. The LTE system is used for scheduling PUCCH and PDCCH resources, and achieves the purpose of reducing system scheduling overhead.

同时，由于SPS也是基于基站调度的资源分配方式，以使在将所述SPS用于本实施例所示的第一CAM数据包传输的过程中，能够有效的避免不同的V-UE间的相互干扰、克服基于自由竞争的资源分配方式所造成的CAM数据包碰撞问题。At the same time, since the SPS is also a resource allocation manner based on the base station scheduling, in the process of using the SPS for the first CAM data packet transmission shown in this embodiment, the mutual interaction between different V-UEs can be effectively avoided. Interference and overcome the CAM packet collision problem caused by free competition based resource allocation.

考虑到车辆在一定行驶速度、加速度、角速度状态下，V-UE所生成的CAM数据包也将呈现出一定的周期性到达特性，而SPS作为一种技术手段，能够实现基于调度的CAM业务资源分配、并降低相应调度开销。Considering that the vehicle is in a certain driving speed, acceleration and angular velocity state, the CAM data packet generated by the V-UE will also exhibit a certain periodic arrival characteristic, and SPS as a technical means can realize the scheduling-based CAM service resource. Allocate and reduce the corresponding scheduling overhead.

对所述SPS的具体实现原理和配置方式为现有技术，在本实施例中不做赘述。The specific implementation principle and configuration manner of the SPS are the prior art, and are not described in this embodiment.

应用现有LTE系统中的SPS机制需要满足两个基本的前提条件：一个是：要求业务的数据包生成间隔需相等(数据包生成间隔为相邻的两个数据包生成的时刻的差)，也就是说数据包具有一个固定的生成周期，并按此周期性到达；另一个是：要求业务的数据包大小需相同，即每个数据包大小固定、数据包定长。The application of the SPS mechanism in the existing LTE system needs to meet two basic preconditions: one is: the data packet generation interval of the required service needs to be equal (the packet generation interval is the difference between the time when two adjacent data packets are generated), That is to say, the data packet has a fixed generation period and arrives periodically according to this; the other is: the data packet size of the required service needs to be the same, that is, each data packet size is fixed and the data packet is fixed.

然而，所述CAM数据包的传输难以满足这两个基本的前提条件： However, the transmission of the CAM data packet is difficult to meet these two basic prerequisites:

因所述CAM数据包的生成间隔和车辆行驶状态有关，即车辆行驶状态改变满足一定触发条件时，相邻的两个所述CAM数据包生成间隔就不会相等；When the generation interval of the CAM data packet is related to the driving state of the vehicle, that is, when the driving state change of the vehicle meets a certain triggering condition, the adjacent two CAM data packet generation intervals are not equal;

又因，相邻的两个所述CAM数据包的数据包大小并不一定相同；Moreover, the data packets of the two adjacent CAM data packets are not necessarily the same size;

以下对所述CAM数据包的数据包大小进行说明：The packet size of the CAM packet is described below:

CAM数据包可分为高频CAM数据包和低频CAM数据包，且每种CAM数据包都具有可变的数据包大小。CAM packets can be divided into high frequency CAM packets and low frequency CAM packets, and each CAM packet has a variable packet size.

其中，高频CAM数据包的发送频率较高，其数据包生成间隔短，且数据包相对较小，不大于150Byte；Wherein, the transmission frequency of the high frequency CAM data packet is relatively high, the data packet generation interval is short, and the data packet is relatively small, not more than 150 Byte;

而低频CAM数据包的发送频率较低，其数据包生成间隔长，往往在多个高频CAM数据包发送之后才会产生一个，且低频CAM数据包也较大，但不大于700Byte。The low-frequency CAM data packet has a low transmission frequency, and the data packet generation interval is long, and is often generated after a plurality of high-frequency CAM data packets are transmitted, and the low-frequency CAM data packet is also large, but is not more than 700 bytes.

也就是说，尽管V-UE所产生的CAM数据包在一定车辆行驶状态下呈现周期性到达的特性，但随着车辆行驶状态的变化，其数据包生成间隔也将在不同生成周期之间发生改变；因而无法保证CAM数据包具备一个唯一、固定的到达周期、难以满足现有SPS机制对数据包周期性到达的要求。That is to say, although the CAM data packet generated by the V-UE exhibits a periodic arrival characteristic in a certain vehicle running state, the packet generation interval will occur between different generation periods as the vehicle traveling state changes. Change; thus there is no guarantee that the CAM packet has a unique, fixed arrival period, and it is difficult to meet the requirements of the existing SPS mechanism for the periodic arrival of the data packet.

且V-UE每次所生成的CAM数据包既可能是高频也可能是低频，且其均具有可变的数据包大小；所以，CAM业务也无法完全满足现有SPS机制对于数据包大小固定的要求。And each time the V-UE generates CAM data packets, which may be high frequency or low frequency, and both have variable packet sizes; therefore, the CAM service cannot fully satisfy the existing SPS mechanism for fixed packet size. Requirements.

鉴于上述CAM消息“数据包到达周期可变、数据包大小不固定”的特性，如果直接应用LTE系统中的SPS机制为CAM消息进行资源分配，将会造成数据包达到时无资源可用、或预配置的资源浪费等问题，使得所分配的资源无法保证CAM消息数据包的有效传输。In view of the above-mentioned CAM message "variable data packet arrival period and data packet size is not fixed", if the SPS mechanism in the LTE system is directly applied to allocate resources for CAM messages, no resource will be available when the data packet is reached, or The resource waste of the configuration is such that the allocated resources cannot guarantee the effective transmission of the CAM message data packet.

另外，现有SPS直接应用于CAM消息传输的另一个重要缺点在于：现有LTE系统中通常利用RRC信令重配为SPS资源配置相应的周期及参数；In addition, another important disadvantage that the existing SPS is directly applied to the CAM message transmission is that the existing LTE system usually uses the RRC signaling reconfiguration to configure the corresponding period and parameters for the SPS resource;

由于CAM消息存在多个数据包到达周期，因此当其周期发生改变时，现有SPS需要通过RRC信令交互为其重新配置相应其周期和参数，带来RRC信令开销；同时RRC信令的交互通常时延较高，不利于CAM消息的实时传输，这对于CAM业务这一类与车辆安全相关的消息来说，将产生很大的影响。Since there are multiple data packet arrival periods in the CAM message, when the period changes, the existing SPS needs to reconfigure its corresponding period and parameters through RRC signaling interaction, which brings RRC signaling overhead; The interaction usually has a high delay, which is not conducive to the real-time transmission of CAM messages, which will have a great impact on the CAM service, which is related to vehicle safety.

综上，直接将现有的SPS技术应用于CAM消息资源分配存在以下两方面 缺点：In summary, the application of existing SPS technology directly to CAM message resource allocation has the following two aspects: Disadvantages:

1、无法适用于CAM消息“数据包周期不固定，数据包大小可变”的业务特性；1, can not be applied to the CAM message "data packet period is not fixed, the packet size is variable" business characteristics;

2、耗费RRC信令，并引入较高时延。2. It consumes RRC signaling and introduces a higher delay.

本实施例为了在CAM数据包满足“数据包周期性到达、数据包大小固定”情况下能够实现一次授权，周期使用，从而有效节省系统用于调度指示的PDCCH资源，而且还能够有效的节省RRC信令开销，降低RRC信令的交互时延，以利于CAM消息的实时传输，则基站预先统计若车辆当前的行驶状态满足所述触发条件时，所述V-UE所生成的所述第一CAM数据包所有可能的生成间隔，以使所述基站的MAC层为所述V-UE配置分别与各所述第一所述CAM数据包的生成间隔对应的SPS资源的周期和参数，以使第一CAM数据包所有可能的生成间隔通过所述预置对应关系分别与不同的半静态调度SPS资源周期对应；In this embodiment, the RRC data packet can be used for one-time authorization and periodic use when the data packet is periodically received and the data packet size is fixed, thereby effectively saving the PDCCH resource used by the system for scheduling indication, and also effectively saving RRC. The signaling overhead reduces the interaction delay of the RRC signaling to facilitate real-time transmission of the CAM message, and the base station pre-counts the first generated by the V-UE if the current driving state of the vehicle satisfies the trigger condition. All possible generation intervals of the CAM data packet, so that the MAC layer of the base station configures, for the V-UE, the period and parameters of the SPS resources respectively corresponding to the generation interval of each of the first CAM data packets, so that All possible generation intervals of the first CAM data packet respectively correspond to different semi-persistent scheduling SPS resource periods through the preset correspondence relationship;

所述第一CAM数据包的生成间隔等于通过所述预置对应关系与所述第一CAM数据包的生成间隔对应的SPS资源的周期；The generation interval of the first CAM data packet is equal to a period of the SPS resource corresponding to the generation interval of the first CAM data packet by the preset correspondence relationship;

且所述基站还为每个SPS资源的周期配置调制编码机制、传输功率、无线资源数等参量进行配置，具体的配置参数在本实施例中不做限定；The base station is configured to configure a modulation and coding mechanism, a transmission power, and a radio resource number for each SPS resource. The specific configuration parameters are not limited in this embodiment.

所述基站即可根据所有可能的第一CAM数据包的生成间隔以及与各第一所述CAM数据包的生成间隔对应的SPS资源的周期和参数生成所述预置对应关系；The base station may generate the preset correspondence according to a generation interval of all possible first CAM data packets and a period and a parameter of an SPS resource corresponding to a generation interval of each first CAM data packet;

所述基站在激活所述SPS资源时，能够根据所述V-UE发送的第一CAM数据包的生成间隔确定与该第一CAM数据包的生成间隔对应的SPS资源的周期，进而通过向所述V-UE发送激活消息以激活周期等于该第一CAM数据包的生成间隔的SPS资源；When the base station activates the SPS resource, the base station can determine a period of the SPS resource corresponding to the generation interval of the first CAM data packet according to the generation interval of the first CAM data packet sent by the V-UE, and further Said V-UE transmitting an activation message to activate an SPS resource whose period is equal to a generation interval of the first CAM data packet;

且因所述基站通过所述激活消息通知所述V-UE激活周期等于该第一CAM数据包的生成间隔的SPS资源，而使得基站无需利用RRC信令重配为SPS资源配置相应的周期及参数，从而可有效的节省RRC信令开销，降低RRC信令的交互时延；And the base station notifying the SPS resource that the V-UE activation period is equal to the generation interval of the first CAM data packet by using the activation message, so that the base station does not need to use the RRC signaling reconfiguration to configure the corresponding period for the SPS resource and Parameters, thereby effectively saving RRC signaling overhead and reducing the interaction delay of RRC signaling;

所述基站将已生成的所述预置对应关系进行存储。 The base station stores the generated preset correspondence.

为更好的理解本发明实施例，以下对第一所述CAM数据包的生成间隔与车辆的速度、加速度、行驶方向等车辆行驶动态的对应关系进行举例说明，需明确的是，本实施例对该对应关系不做限定，以下只是对所述第一CAM数据包的生成间隔与车辆的速度、加速度、行驶方向等车辆行驶动态的对应关系的一种示例；For a better understanding of the embodiments of the present invention, the correspondence between the generation interval of the first CAM data packet and the driving dynamics of the vehicle such as the speed, the acceleration, and the traveling direction of the vehicle is exemplified, and it should be clarified that the embodiment is The correspondence relationship is not limited. The following is only an example of the correspondence between the generation interval of the first CAM data packet and the vehicle driving dynamics such as the speed, acceleration, and traveling direction of the vehicle;

具体的，本实施例中，所述基站即可根据所有可能的所述第一CAM数据包的生成间隔与车辆的速度、加速度、行驶方向等车辆行驶动态的对应关系生成所述预置对应关系；Specifically, in this embodiment, the base station may generate the preset correspondence according to the correspondence between the possible generation intervals of the first CAM data packet and the vehicle driving dynamics such as the speed, the acceleration, and the traveling direction of the vehicle. ;

从前述CAM消息业务特性可知，车辆对于CAM业务消息的产生和发送非常频繁，基本上处于毫秒量级，消息密度很大；另一方面，由于CAM业务传递车辆的安全消息、事关车辆行驶安全，基本上需要从车辆启动开始直至车辆熄火驻车为止持续不停地传输，因而CAM消息持续时间长；此外，在城区的交通路口、立交桥、繁华地段等场景，经常会出现车流量较大、车辆密集等情况，导致CAM业务量急剧增加。这些都使得V2V通信与已有LTE蜂窝网络中用户的移动无线业务存在显著的不同。It can be known from the foregoing CAM message service characteristics that the vehicle generates and transmits CAM service messages very frequently, basically in the order of milliseconds, and the message density is very large; on the other hand, because the CAM service transmits the safety message of the vehicle, it is related to the safety of the vehicle. Basically, it needs to be continuously transmitted from the start of the vehicle until the vehicle is turned off, so the CAM message lasts for a long time; in addition, in the traffic intersections, overpasses, and busy areas of the urban area, traffic flow is often large. Intensive vehicles and other conditions have led to a sharp increase in CAM traffic. These all make V2V communication significantly different from the mobile wireless service of users in existing LTE cellular networks.

The period of the CAM data packet is changed, and the base station activated target resource (the first SPS resource and/or the second SPS resource) cannot be used to transmit the next CAM data packet, then the base station The target resource is released, and the V-UE deactivates the target resource, thereby effectively avoiding waste of the SPS resource.

从本发明前述实施例的信令流程中可以看到，V-UE向基站上报的缓存状态信息，即上述实施例中的BSR-V，及其所携带的信息，是实现本发明技术方案的关键因素。尽管现有LTE系统中，用户终端(UE)上行数据传输也需要以MAC层控制单元(MAC Control Element,MAC CE)向基站上报BSR，告知基站目前缓冲区中待传输的数据大小和业务类型；然而，现有LTE系统所采用的BSR无法直接用来支持本发明中技术方案功能的实现。It can be seen from the signaling flow of the foregoing embodiment of the present invention that the cache state information reported by the V-UE to the base station, that is, the BSR-V in the foregoing embodiment, and the information carried therein are the technical solutions of the present invention. The key factor. In the existing LTE system, the user terminal (UE) uplink data transmission needs to report the BSR to the base station by using a MAC Control Element (MAC CE) to inform the base station of the current data size and service type to be transmitted in the buffer. However, the BSR adopted by the existing LTE system cannot be directly used to support the implementation of the technical solution function in the present invention.

鉴于此，本实施例将提出一种面向V2V通信中CAM业务传输的BSR-V格式设计的技术方案，以实现本发明上述各实施例中BSR-V所需具备的功能。In view of this, the present embodiment will provide a technical solution for designing a BSR-V format for CAM service transmission in V2V communication, in order to implement the functions required for the BSR-V in the above embodiments of the present invention.

以下对各BSR-V消息各格式进行详细说明：需明确的是，下述对各所述BSR-V消息的格式的说明为可选的实施例不做限定，只要各BSR-V消息能够实现上述实施例的资源配置即可；The following describes each format of each BSR-V message in detail: it should be clarified that the following description of the format of each of the BSR-V messages is not limited as long as the optional embodiment is implemented, as long as each BSR-V message can be implemented. The resource configuration of the above embodiment may be;

首先结合图12所示对BSR-V的格式进行举例说明：First, the format of the BSR-V is illustrated in conjunction with FIG. 12:

所述BSR-V的大小为一个字节(1Byte)，由“TC”、“SIZE”和“INTERV”三个域组成组成；其中，TC域占1bit，SIZE域占3bits，INTERV域占4bits；The size of the BSR-V is one byte (1 Byte), and is composed of three domains: "TC", "SIZE", and "INTERV"; wherein the TC domain occupies 1 bit, the SIZE domain occupies 3 bits, and the INTERV domain occupies 4 bits;

下面对每个域的具体含义进行说明：The following describes the specific meaning of each domain:

“TC”：该域取值为“0”或“1”；用来指示所述第一CAM数据包生成时刻开始计时直至经过所述第一CAM数据包的生成间隔的时间内是否生成CAM数据包；"TC": the value of the field is "0" or "1"; it is used to indicate whether the first CAM packet generation time starts counting until the CAM data is generated within a time interval of the generation interval of the first CAM data packet. package;

“SIZE”：表示第一CAM数据包的大小，该域取值范围为“000～111”；用来指示当前CAM数据包的大小；由于CAM数据包大小可变，难以对每个具体数据包大小都进行完全精确的表示；"SIZE": indicates the size of the first CAM packet, the value range of the field is "000 ~ 111"; used to indicate the size of the current CAM packet; because the CAM packet size is variable, it is difficult to each specific packet The size is fully accurate;

因而，本实施例中利用“000～111”中的每一个取值表示一个数据包大小的范围：落在某一个取值所对应范围内的数据包大小均由该取值进行表示。Therefore, in each embodiment, the value of each of "000 to 111" is used to represent a range of data packet size: the size of the data packet falling within a range corresponding to a certain value is represented by the value.

例如，考虑到CAM数据包最大不超过700Byte，本实施例中将采用“SIZE ＝000”表示“0～75Byte”、“Size＝001”表示“76～150Byte”、“SIZE＝010”表示“151～200Byte”、“SIZE＝011”表示“201～300Byte”、“SIZE＝100”表示“301～400Byte”、“SIZE＝101”表示“401～500Byte”、“SIZE＝110”表示“501～600Byte”、“SIZE＝111”表示“601～700Byte”；For example, considering that the CAM packet does not exceed 700 bytes at the maximum, "SIZE" will be used in this embodiment. =000" indicates "0 to 75 Byte", "Size = 001" indicates "76 to 150 Byte", "SIZE = 010" indicates "151 to 200 Byte", and "SIZE = 011" indicates "201 to 300 Byte", "SIZE = 100". "301 to 400 Byte" and "SIZE=101" indicate "401 to 500 Byte", "SIZE=110" indicates "501 to 600 Byte", and "SIZE=111" indicates "601 to 700 Byte";

按照上述说明，大小为118Byte的高频数据包所对应的Size域取值为“001”，而大小为694Byte低频数据包对应的Size域取值为“111”，以此类推；According to the above description, the size field corresponding to the high-frequency data packet of size 118 Byte is "001", and the value of the size field corresponding to the low-frequency data packet of 694 Byte is "111", and so on;

此外，由于高频数据包大小不超过150Byte，所述V-UE和所述基站均可以通过该域的取值判断某个数据包是高频消息还是低频消息，即如果为当前数据包上报的BSR-V的SIZE域的值落在“000～001”范围内则该数据包即为高频CAM数据包，否则为低频CAM数据包；该域的主要作用是在V-UE为第一CAM数据包申请DS资源时时上报该数据包的大小。In addition, since the high-frequency data packet size does not exceed 150 Bytes, the V-UE and the base station can determine whether a certain data packet is a high-frequency message or a low-frequency message by using the value of the domain, that is, if the current data packet is reported. If the value of the SIZE field of the BSR-V falls within the range of "000 to 001", the data packet is a high frequency CAM data packet, otherwise it is a low frequency CAM data packet; the main role of the domain is that the V-UE is the first CAM. When a data packet is applied for a DS resource, the size of the data packet is reported.

“INTERV”：表示CAM数据包的生成间隔TCurr，该域取值为“0000～1111”；该域用于在TCurr＝TLast时向基站上报第一CAM数据包所对应生成间隔TCurr信息；所述TLast为第二CAM数据包的生成间隔；"INTERV": indicates the generation interval TCurr of the CAM data packet, and the value of the field is "0000 to 1111"; the field is used to report the generation interval TCurr information corresponding to the first CAM data packet to the base station when TCurr=TLast; TLast is a generation interval of the second CAM data packet;

根据表1～表3，第一CAM数据包的周期共有10种可能的取值，因此为该域设置4个bits(最多可表示16种可能)对所有可能的TCurr进行表示；其中，该域“0000～1001”中的每个取值分别对应于表1～表3中的一个CAM数据包周期的大小；According to Tables 1 to 3, there are 10 possible values for the period of the first CAM packet, so 4 bits are set for the domain (up to 16 possibilities are possible), and all possible TCurrs are represented; wherein, the domain Each of the values of "0000 to 1001" corresponds to the size of one CAM packet period in Tables 1 to 3, respectively;

例如，本实施例中利用“INTERV＝0000”表示TCurr＝100ms、“INTERV＝0001”表示TCurr＝200ms，……，“INTERV＝1001”表示TCurr＝1sec；同时，该域利用“INTERV＝1111”表示事件“TCurr≠TLast”，一旦基站收到该域的取值为“INTERV＝1111”，则基站判断第一CAM数据包的周期等级已发生改变；其他取值“1010～1110”则作为预留位，支持可能的功能扩展。For example, in the present embodiment, "INTERV=0000" means TCurr=100ms, "INTERV=0001" means TCurr=200ms, ..., "INTERV=1001" means TCurr=1sec; meanwhile, the domain uses "INTERV=1111" The event "TCurr≠TLast" is indicated. Once the value of the field received by the base station is "INTERV=1111", the base station determines that the period level of the first CAM data packet has changed; the other values "1010~1110" are used as pre- Stay in place to support possible feature extensions.

例如通过设置所述BSR-V TC域的取值为“TC＝1”(此时无论其他域取指如何)表示事件“CAM数据包生成间隔变大”；For example, by setting the value of the BSR-V TC domain to "TC=1" (in this case, regardless of other domain fetches), the event "CAM packet generation interval becomes larger" is indicated;

还例如，若在所述BSR-V中需要标明所述第一CAM数据包的生成间隔与所述第二CAM数据包的生成间隔是否相等，则将通过设置“TC＝0”以及“取值范围为“000～001”的SIZE域取值”表示第一CAM数据包为高频消息， 并按照上述INTERV域的定义、通过“INTERV域的取值”表示TCurr与TLast是否相等以及示TCurr的大小；For example, if it is necessary to indicate whether the generation interval of the first CAM data packet and the generation interval of the second CAM data packet are equal in the BSR-V, then "TC=0" and "value" are set. The value of the SIZE field in the range of "000 to 001" indicates that the first CAM packet is a high frequency message. And according to the definition of the above INTERV domain, through the "value of the INTERV field" indicates whether the TCurr and the TLast are equal and the size of the TCurr;

还例如需要通过BSR-V指示当前的CAM数据包为低频CAM数据包，则将通过设置“TC＝0”以及“取值范围为“010～111”的Size域取值”表示第一CAM数据包是低频CAM消息，并按照上述INTERV域的定义，通过“INTERV域的取值”指示TCurr与TLast是否相等。For example, if the current CAM data packet needs to be indicated by the BSR-V as a low-frequency CAM data packet, the first CAM data will be represented by setting "TC=0" and "Size field value of the value range "010-111". The packet is a low frequency CAM message, and according to the definition of the INTERV field above, whether the value of the INTERV field is equal to whether the TCurr and the TLast are equal.

此外，由于负责无线资源分配的调度器位于基站中，基站本身明确知道当前某V-UE是否已经配置了SPS资源，因并无需V-UE通过BSR-V对其进行指示。In addition, since the scheduler responsible for radio resource allocation is located in the base station, the base station itself knows explicitly whether the current V-UE has configured the SPS resource, because the V-UE does not need to indicate it through the BSR-V.

以下结合图13所示的对所述BSR-V数据的另一种格式进行说明，其大小为一个字节(1Byte)，由“TC“、“H/L”和“SIZE”三个域组成；Another format of the BSR-V data shown in FIG. 13 is described below, and its size is one byte (1 Byte), which is composed of three domains of "TC", "H/L", and "SIZE". ;

其中，TC域占1bit，H/L域占1bit，SIZE域占6bits，且该BSR-V将利用TC域和H/L域的四种不同组合表示四种不同的含义，分别用来指示BSR-V上报对应的四种不同情况，下面对每个域的具体含义进行说明：The TC domain occupies 1 bit, the H/L domain occupies 1 bit, and the SIZE field occupies 6 bits. The BSR-V uses four different combinations of the TC domain and the H/L domain to represent four different meanings, which are used to indicate the BSR. -V reports four different situations. The following describes the specific meaning of each domain:

TC和H/L：这两个域名一共两个比特，其所有可能的四中组合所表示的含义如表4所示：TC and H/L: These two domain names have a total of two bits. The meanings of all possible combinations of four are shown in Table 4:

表4Table 4

Figure PCTCN2015085384-appb-000005
Figure PCTCN2015085384-appb-000005

SIZE：表示第一CAM数据包大小，该域取值范围为“000000”～“111111”；其用来指示当前CAM数据包的大小，利用“000000”～“111111”中的某一取值表示一个数据包大小的范围。SIZE: indicates the size of the first CAM packet. The value ranges from "000000" to "111111". It is used to indicate the size of the current CAM packet. It is represented by a value in "000000" to "111111". A range of packet sizes.

与上述针对图12所示的BSR-V相比，由于并不需要指示TCurr信息，因 图13所示的SIZE域有更多的比特来表示数据包的大小，进而可以将数据包的大小表示的更为精确。Compared with the above-mentioned BSR-V shown in FIG. 12, since it is not necessary to indicate the TCurr information, The SIZE field shown in Figure 13 has more bits to indicate the size of the packet, which in turn makes the size of the packet more accurate.

例如，考虑到CAM数据包最大不超过700Byte，本实施例中每个Size的取值间将表示一个12Byte大小的区间：采用“SIZE＝000000”表示“0～12Byte”、“SIZE＝000001”表示“13～24Byte”、“SIZE＝000010”表示“25～36Byte”、……、“SIZE＝111001”表示“684～696Byte”、“SIZE＝111010”表示“697～700Byte”；For example, considering that the CAM data packet does not exceed 700 bytes at the maximum, the value of each size in this embodiment will represent a 12-byte size interval: "SIZE=000000" means "0~12Byte" and "SIZE=000001" "13 to 24 Byte" and "SIZE = 000010" indicate "25 to 36 Byte", ..., "SIZE = 11001" indicates "684 to 696 Byte", and "SIZE = 11010" indicates "697 to 700 Byte";

SIZE域的其他取值“Size＝111011～111111”则用作预留位，支持可能的功能扩展；该域的主要作用是在V-UE为第一CAM数据包申请DS资源时时上报该数据包的大小。The other value of the SIZE field, "Size=111011~111111", is used as a reserved bit to support possible function expansion. The main function of this field is to report the data packet when the V-UE requests DS resources for the first CAM data packet. the size of.

例如通过设置TC域和H/L域的取值为“TC＝0”及“H/L＝0”表示事件“CAM数据包生成间隔变大”；这样，即可实现图11所示的实施例“CAM数据包生成间隔变大触发SPS资源释放”技术方案中所需的BSR-V功能；For example, by setting the values of the TC field and the H/L field to "TC=0" and "H/L=0", the event "CAM packet generation interval becomes larger" is displayed; thus, the implementation shown in FIG. 11 can be realized. The BSR-V function required in the technical solution of "the CAM packet generation interval is large to trigger the SPS resource release";

图6所示的实施例中，基站只需得知第一CAM数据包为高频信息，即可根据是否已经配置了SPS资源并执行相应功能；In the embodiment shown in FIG. 6, the base station only needs to know that the first CAM data packet is high frequency information, and may perform the corresponding function according to whether the SPS resource has been configured;

为此将通过设置“TC＝0”以及“H/L＝1”表示当前是高频CAM数据包为高频消息；这样，即可以实现图6所示的实施例中BSR-V所需的全部功能；To this end, by setting "TC=0" and "H/L=1", it is indicated that the high frequency CAM data packet is a high frequency message; thus, the required BSR-V in the embodiment shown in FIG. 6 can be realized. All functions;

若需通过BSR-V指示TCurr与TLast是否相等，为此则将通过设置“TC＝1”以及“H/L＝0”表示第一CAM数据包是低频CAM消息且TCurr≠TLast，而通过设置“TC＝1”以及“H/L＝1”表示第一CAM数据包是低频CAM消息且TCurr＝TLast；If it is necessary to indicate whether TCurr and TLast are equal by BSR-V, by setting "TC=1" and "H/L=0", it means that the first CAM packet is a low frequency CAM message and TCurr TLast, and by setting "TC=1" and "H/L=1" indicate that the first CAM data packet is a low frequency CAM message and TCurr=TLast;

同样，基站本身明确知道当前某V-UE是否已经配置了SPS资源，因并无需V-UE通过BSR-V对其进行指示。Similarly, the base station itself knows explicitly whether the current V-UE has configured the SPS resource, because the V-UE does not need to indicate it through the BSR-V.

以下对BSR-V的MAC子头数据格式进行说明：The following describes the MAC subheader data format of the BSR-V:

在LTE系统中，BSR是以MAC控制单元的形式进行传输的，而每个MAC单元需要一个MAC子头(sub-header)，使得基站通过读取MAC子头的指示，获取相应MAC控制单元的功能。由于前述所涉及的BSR-V的数据结构和表达的含义与现有LTE系统中的BSR并不相同，需要为上述所设计的BSR-V重新定义一个MAC子头。 In the LTE system, the BSR is transmitted in the form of a MAC control unit, and each MAC unit needs a MAC sub-header, so that the base station obtains the corresponding MAC control unit by reading the indication of the MAC sub-header. Features. Since the data structure and the meaning of the expression of the BSR-V mentioned above are not the same as those of the existing LTE system, it is necessary to redefine a MAC sub-header for the BSR-V designed above.

以下结合图14所示对BSR-V的MAC子头数据格式进行说明：The following describes the MAC subheader data format of the BSR-V in conjunction with FIG. 14:

BSR-V对应的MAC子头数据格式为：其大小为一个字节(1Byte)，由“LCID“、“E”和“R”三个域组成。所涉及的BSR-V基于LTE系统中的上行通信的MAC子头进行设计。该MAC子头的数据格式以及“E”“R”域的含义与现有LTE中的上行MAC子头完全相同，而区别之处在于：本实施例中将逻辑信道标识(LCID域)的值设置为“01011”，并通过LCID＝01011来表示该MAC子头所指示MAC控制单元是车辆的BSR-V。The data format of the MAC subheader corresponding to the BSR-V is: its size is one byte (1 Byte), and it consists of three fields: "LCID", "E", and "R". The BSR-V involved is designed based on the MAC subheader of uplink communication in the LTE system. The data format of the MAC sub-header and the meaning of the "E" and "R" fields are identical to the uplink MAC sub-headers in the existing LTE, and the difference is that the value of the logical channel identifier (LCID field) is used in this embodiment. Set to "01011" and indicate that the MAC control unit indicated by the MAC subheader is the BSR-V of the vehicle by LCID=01011.

这是因为在现有LTE系统中，需要为唯一的LCID值来指示相应的MAC控制单元或者MAC层的数据负载；而取值范围为“0000”、“00001～01010”以及“11010～11111”的LCID值已经被占用，只有范围为“00001～01010”的LCID值是预留、未被使用的，因此可以再其中选择一个值来表示BSR-V。因此，本实施例选择“01011”作为指示BSR-V的LCID值。如果基站接收到的LCID值为“01011”的MAC子头，则可以判断出其所对应的MAC控制单元为BSR-V，所需分配资源的业务为车辆的CAM消息，进而按照本发明中的实施例进行CAM业务的资源分配。This is because in the existing LTE system, it is necessary to indicate the data load of the corresponding MAC control unit or the MAC layer as a unique LCID value; and the value ranges are "0000", "00001 to 01010", and "11010 to 11111". The LCID value is already occupied. Only the LCID value in the range of "00001~01010" is reserved and unused, so one of the values can be selected to represent the BSR-V. Therefore, this embodiment selects "01011" as the LCID value indicating the BSR-V. If the base station receives the MAC sub-header with the LCID value of "01011", it can be determined that the corresponding MAC control unit is the BSR-V, and the service required to allocate the resource is the CAM message of the vehicle, and further according to the present invention. The embodiment performs resource allocation of the CAM service.
