Description

一种通信方法及相关设备
本申请要求于2018年08月10日提交中国国家知识产权局、申请号为201810912254.9、发明名称为“一种通信方法及相关设备”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及通信技术领域，尤其涉及一种车联网中涉及数据传输的优先级的通信方法及相关设备。
背景技术
车联网V2X(vehicle to X)是智能交通运输系统的关键技术，被认为是物联网体系中最有产业潜力、市场需求最明确的领域之一，具有应用空间广、产业潜力大、社会效益强的特点，对促进汽车和信息通信产业创新发展，构建汽车和交通服务新模式新业态，推动自动驾驶技术创新和应用，提高交通效率和安全水平具有重要意义。车联网一般是指通过装载在车上的传感器、车载终端设备等提供车辆信息，实现车辆到车辆(vehicle to vehicle，V2V)，车辆到基础设施(vehicle to infrastructure，V2I)，车辆到网络(Vehicle to Network，V2N)以及车辆到行人(vehicle to pedestrian，V2P)之间的相互通信的通信网络。
示例性的，本申请中，网络设备和第一终端设备之间的无线通信接口可以定义为Uu口，基于Uu口，第一终端设备和网络设备之间进行上行通信的无线通信链路可以定义为上行链路(Uplink，UL)；第一终端设备和第二终端设备之间的无线直连通信接口可以定义为PC5口，基于PC5口，第一终端设备与第二终端设备之间进行直连通信的通信链路可以定义为侧行链路(sidelink，SL)。本申请中的Uu口可以是LTE制式或者NR制式等通信系统中的Uu口，也可以叫空口；本申请中的PC5口可以是LTE制式或者NR制式等通信系统中的PC5口。
在V2X场景下，第一终端设备或者第二终端设备可以是车辆设备，网络设备可以是无线接入网设备，比如基站。对于车辆设备而言，当Uu口存在极高可靠极低时延需求场景(Ultra-Reliable and Low-Latency Communication，URLLC)业务时(示例性的，在发生交通事故后，在司机和乘客失去知觉无法拨打电话，车辆设备会向基站上报自动呼叫紧急救援业务)，目前的机制无法兼顾SL和UL链路上的数据传输需求，比如时延、可靠性等需求，又比如，针对不同链路上的业务发生发生传输冲突的问题，目前机制也无法解决。
发明内容
现有机制中，一方面，终端设备获取侧行链路上的PPPP门限值，然后将终端设备的侧行链路的媒体接入控制层协议数据单元中具有最高优先级的PPPP值和一个门限值比较，如果该具有最高优先级的PPPP值对应的优先级高于该门限值对应的优先级，则优先传输侧行链路媒体接入控制层协议数据单元，如果该PPPP值对应的优先级低于该门限值对应的优先级，则优先传输上行链路媒体接入控制层协议数据单元，这种方式只考虑侧行链路传输需求和门限值的比较来判断UL和SL的传输优先级顺序，存在的问题包括：当该终端设备获取的门限值对应的优先级过低时，会牺牲SL链路上的数据传输需求；当终端设备获取的门限值对应的优先级过高时，又会频繁的发送SL上的数据，从而牺牲UL链路上的数据传输需求。 所以，如何兼顾SL和UL链路上的数据传输需求，比如时延、可靠性需求，是一个亟待解决的问题。
另一方面，现有机制中Uu口上行链路的逻辑信道的待传数据(Uu logical channel data，Uu LCH data)的优先级比侧行链路缓存状态报告媒体接入层控制单元(sidelink buffer status report media access control control element，SL BSR MAC CE)优先级低，SL BSR MAC CE优先级比上行链路侧行链路缓存状态报告媒体接入层控制单元(uplink buffer status report media access control control element，UL BSR MAC CE)的优先级低。这种将Uu LCH data，SL BSR MAC CE，UL BSR MAC CE之间的优先级规定成目前机制中的优先级顺序的方法，存在如下问题：比如，当终端设备中通过SL传输的业务需要通过SL BSR MAC CE向网络设备上报缓存状态(Buffer status，BS)信息，以便获取传输资源的同时，终端设备中通过UL传输的上行业务也需要通过UL BSR MAC CE向网络设备上报BS信息，以便获取传输资源，则此时即使通过SL传输的业务的优先级很高，终端设备也无法保证优先上报该业务的BS信息；又比如，如果有优先级很高的业务，如URLLC业务，需要通过UL传输给网络设备，但同时终端设备中通过SL传输的业务需要通过SL BSR MAC CE向网络设备上报缓存状态(Buffer status，BS)信息，以便获取传输资源，则此时终端设备无法保证优先上报通过UL传输的优先级很高的业务，如URLLC业务。

终端设备中的待发送数据无论是触发UL BSR还是SL BSR后，如果没有UL grant进行BSR的发送，那么终端设备会向网络设备发送调度请求(Scheduling Request，SR)，向网络设备申请UL grant进行BSR的发送。现有技术中每个终端设备的所有侧行逻辑信道都只有一套SR配置，导致了当网络设备收到两个不同终端设备的不同SR时，无法区分出不同终端设备的业务优先级，无法进行业务识别和调度。
图11a是本申请实施例提供的通信方法的流程示意图，下面将结合图11a，对本申请实施例的技术方案进行具体的描述，示例性的，图11a所对应的通信方法包括：

本申请实施例提供了一种调度请求方法，网络设备为PC5口不同的侧行逻辑信道配置多套SR配置，通过此方案可以辅助网络设备进行更好的业务识别和调度，例如当网络设备收到两个不同终端设备的不同SR配置时，可以区分出不同终端设备的业务优先级。
现有技术中，在V2X的一种模式下，终端设备是通过自身监测(sensing)资源并利用资源排除门限值选择合适的目标终端设备进行数据发送操作的，但现有技术中的资源排除门限值仅考虑到PPPP值的影响，对于高可靠性业务，需要信道条件更好的资源进行传输，以保障高可靠性业务更高的传输可靠性，因此，对于不同可靠性需求的业务，其在资源排除时应采用不同的处理方式。
图12是本申请实施例提供的通信方法的流程示意图，下面将结合图12，对本申请实施例的技术方案进行具体的描述，示例性的，图12所对应的通信方法包括：
操作1201：获得PPPR的相关参数；
第一种可选的方式为：获得监测(sensing)过程中的源终端设备和目标终端设备之间的PPPR值的差值，再利用源终端设备和目标终端设备之间的PPPR值的差值得到对现有技术中的资源排除门限值的调整量。；

PPPR1 TH1 TH2 TH3 TH4
PPPR2 TH5 TH6 TH7 TH8
PPPR3 TH9 TH10 TH11 TH12
PPPR4 TH13 TH14 TH15 TH16
第四种可选的方式为：定义一个综合考虑PPPP值和PPPR值的表格代替现有技术中的PPPP值表格。此时，如果PPPP的取值为2种，PPPR取值为2种，每一种PPPP取值分2种PPPR取值，则相应的行数和列数均为4，如表9所示，表9中行值代表目标终端设备业务的PPPR值，列值代表源终端设备业务的PPPR值。
表9：
Figure PCTCN2019100010-appb-000008
和表9类似的方法，如果PPPP的取值为4种，PPPR取值为8种，每一种PPPP取值分8种PPPR取值，则相应的行数和列数均为32；如果PPPP的取值为8种，PPPR取值为8种，每一种PPPP取值分8种PPPR取值，则相应的行数和列数取值均为64。

操作1202：利用获得的PPPR相关参数建立资源排除方法；
基于操作1201的第一种可选方式的一种可选方式为：利用操作1201中获得的调整量对现有技术中的资源排除门限值进行调整。当源发送车辆设备具有较高的可靠性需求时(即PPPR值较低时)，利用该调整量降低现有技术中的资源排除门限值；当源发送车辆设备具有较低的可靠性需求时(即PPPR值较高时)，利用该调整量提高现有技术中的资源排除门限值。
基于操作1201的第二种可选方式的一种可选方式为：资源排除时需同时考虑为每个PPPR值配置的资源排除门限值和现有技术中的PPPP门限值表格，当第一终端设备所监测的 参考信号接收功率(Reference signal received power，RSRP)高于该配置的资源排除门限值或者高于PPPP门限值表格中的相应门限值时，排除资源池中的此资源。
基于操作1201的第三种可选方式的一种可选方式为：确定资源排除门限值时，同时考虑为PPPR值配置的表格中的门限值和为PPPP值配置的表格中的门限值。示例性的，可以规定当RSRP同时大于两张表格中的门限值才可以排除sensing到的资源。
基于操作1201的第四种可选方式的可选方式为：依据所定义的综合考虑PPPP值和PPPR值的表格来重新定义资源排除门限值。
