Description

一种侧行数据传输的方法、装置和系统 技术领域
本申请涉及通信领域，尤其是涉及一种侧行数据传输的方法、装置和系统。
背景技术
车与车(Vehicle to Vehicle，V2V)通信、车与行人V2P(VehicletoPedestrian，V2P)通信或车与基建/网络V2I/N(VehicletoInfrastructure/Network，V2I/N)通信是终端设备(terminal device)之间直接进行通信的技术，即直连通信，V2V、V2P以及V2I/N统称为车联网(Vehicle-To-Everything，V2X)，即车与任何事物相通信。
现有技术中，侧行信息传输采用盲重传的机制，即发送端用户向接收端用户进行固定次数的重传，在信道质量相对比较好的时候，发送端用户进行一次传输后，接收端用户便可以正确译码，因此固定次数的重传导致资源利用率低下。混合自动重传请求(Hybrid Automatic Repeat reQuest，HARQ)机制中，发送端用户收到否定应答(Negative Acknowledgement,NACK)反馈时候触发重传，在接收到应答消息(Acknowledgement，ACK)反馈时，不需要进行重传。在NR侧行通信中，ACK/NACK承载于物理层反馈信道(Physical Sidelink Feedback Channel，PSFCH)中，PSFCH是系统性配置的周期资源，其周期可以由网络设备配置或预配置。HARQ机制中，发送端用户需要等待接收端用户的物理层反馈后决定是否重传，同时用于反馈的PSFCH资源占用了系统资源，导致系统资源利用率低下。

具体实施方式
图1为本申请实施例所涉及的场景示意图，在图1中，第一终端装置与第二终端装置通信，第一终端装置与第二终端装置可能处于同一小区覆盖范围内，也有可能处于不同小区，或者无移动网络覆盖。第一终端装置与第二终端装置之间的通信链路的配置及通信资源可以由用户自己决定，也可以由网络配置。
以下，对本申请实施例中的部分用语进行解释说明，以便于本领域技术人员理解。
1)终端装置，本申请所涉及到的第一终端装置或第二终端装置可以包括各种具有无线通信功能的设备或者此设备中的单元、部件、模块、装置、芯片或者SOC，所述具有无线通信功能的设备例如可以是车载设备、可穿戴设备、计算设备或连接到无线调制解调器的其它设备，移动台(Mobile station，MS)，终端(terminal)或用户设备(User Equipment，UE)等。第一至第二终端装置为车载设备时，可放置或安装在车辆内，车载设备可视为车辆的一部分，也可以视为模块或模组安置于车辆中，车载终端装置也可以称为车载单元(On Board Unit，OBU)。
本申请实施例所涉及的第一或第二终端装置还可以包括向用户提供语音和/或数据连通性的设备，具体的，包括向用户提供语音的设备，或包括向用户提供数据连通性的设备，或包括向用户提供语音和数据连通性的设备。例如可以包括具有无线连接功能的手持式设备、或连接到无线调制解调器的处理设备。该终端设备可以经无线接入网(radio access network，RAN)与核心网进行通信，与RAN交换语音或数据，或与RAN交互语音和数据。该终端装置可以包括用户设备(user equipment，UE)、无线终端设备、移动终端设备、设备到设备通信(device-to-device，D2D)终端设备、车到一切(vehicle to everything，V2X)终端设备、机器到机器/机器类通信(machine-to-machine/machine-type communications，M2M/MTC)终端设备、物联网(internet of things，IoT)终端设备、订户单元(subscriber unit)、订户站(subscriber station)，移动站(mobile station)、远程站(remote station)、接入点(access point，AP)、远程终端(remote terminal)、接入终端(access terminal)、用户终端(user terminal)、用户代理(user agent)、或用户装备(user device)等。例如，可以包括移动电话(或 称为“蜂窝”电话)，具有移动终端设备的计算机，便携式、袖珍式、手持式、计算机内置的移动装置等。例如，个人通信业务(personal communication service，PCS)电话、无绳电话、会话发起协议(session initiation protocol，SIP)话机、无线本地环路(wireless local loop，WLL)站、个人数字助理(personal digital assistant，PDA)、等设备。还包括受限设备，例如功耗较低的设备，或存储能力有限的设备，或计算能力有限的设备等。例如包括条码、射频识别(radio frequency identification，RFID)、传感器、全球定位系统(global positioning system，GPS)、激光扫描器等信息传感设备。
作为示例而非限定，本申请实施例所涉及的第一或第二终端装置还可以是可穿戴设备。可穿戴设备也可以称为穿戴式智能设备或智能穿戴式设备等，是应用穿戴式技术对日常穿戴进行智能化设计、开发出可以穿戴的设备的总称，如眼镜、手套、手表、服饰及鞋等。可穿戴设备即直接穿在身上，或是整合到用户的衣服或配件的一种便携式设备。可穿戴设备不仅仅是一种硬件设备，更是通过软件支持以及数据交互、云端交互来实现强大的功能。广义穿戴式智能设备包括功能全、尺寸大、可不依赖智能手机实现完整或者部分的功能，例如：智能手表或智能眼镜等，以及只专注于某一类应用功能，需要和其它设备如智能手机配合使用，如各类进行体征监测的智能手环、智能头盔、智能首饰等。
终端装置，可以是终端设备，或者也可以是用于实现终端设备的功能的模块，该模块可以设置在终端设备中，或者也可以与终端设备彼此独立设置，该模块例如为芯片、芯片系统或片上系统等。
2)网络装置，例如包括接入网(access network，AN)设备，例如基站(例如，接入点)，可以是指接入网中在空口通过一个或多个小区与无线终端设备通信的设备，或者例如，一种车到一切(vehicle-to-everything，V2X)技术中的网络设备为路侧单元(road side unit，RSU)。基站可用于将收到的空中帧与IP分组进行相互转换，作为终端设备与接入网的其余部分之间的路由器，其中接入网的其余部分可包括IP网络。RSU可以是支持V2X应用的固定基础设施实体，可以与支持V2X应用的其他实体交换消息。网络设备还可协调对空口的属性管理。例如，网络装置可以包括长期演进(long term evolution，LTE)系统或高级长期演进(long term evolution-advanced，LTE-A)中的演进型基站(NodeB或eNB或e-NodeB，evolutional Node B)，或者也可以包括第五代移动通信技术(the 5 th generation，5G)新空口(new radio，NR)系统(也简称为NR系统)中的下一代节点B(next generation node B，gNB)或者也可以包括云接入网(cloud radio access network，Cloud RAN)系统中的集中式单元(centralized unit，CU)和分布式单元(distributed unit，DU)，本申请实施例并不限定。
3)本申请实施例的V2X通信是车与外界进行互联互通，这是未来智能汽车、自动驾驶、智能交通运输系统的基础和关键技术。V2X将在已有的设备到设备(device-to-device，D2D)技术的基础上对V2X的具体应用需求进行优化，需要进一步减少V2X设备的接入时延，解决资源冲突问题。
V2X具体又包括车与车(vehicle-to-vehicle，V2V)、车与路侧基础设施(vehicle-to-infrastructure，V2I)、车与行人(vehicle-to-pedestrian，V2P)的直接通 信，以及车与网络(vehicle-to-network，V2N)的通信交互等几种应用需求。V2V指的是车辆间的通信；V2P指的是车辆与人(包括行人、骑自行车的人、司机、或乘客)的通信；V2I指的是车辆与网络设备的通信，网络设备例如RSU，另外还有一种V2N可以包括在V2I中，V2N指的是车辆与基站/网络的通信。
其中，V2P可以用做给道路上行人或非机动车安全警告。通过V2I，车辆可以与道路甚至其他基础设施，例如交通灯、路障等，进行通信，获取交通灯信号时序等道路管理信息。V2V可以用做车辆间信息交互和提醒，最典型的应用是用于车辆间防碰撞安全系统。V2N是目前应用最为广泛的车联网形式，其主要功能是使车辆通过移动网络，连接到云服务器，使用云服务器提供的导航、娱乐、或防盗等应用功能。
在V2X中，主要是终端设备和终端设备之间的通信。对于终端设备和终端设备之间的传输模式，当前标准协议支持的有广播方式，组播方式，和单播方式。
广播方式：广播方式是指作为发送端的终端设备采用广播的模式进行数据发送，多个终端设备端均能接收来自发送端的侧行链路控制信息(sidelink control information，SCI)和/或侧行链路共享信道(sidelink shared channel，SSCH)。应理解，广播传输中，发送端的终端设备无法获知哪些终端设备会接收所发送的广播数据。
在侧行链路中，保证所有的终端设备都解析来自发送端的控制信息的方式是，发送端不对控制信息的CRC进行加扰，或者发送端使用所有的终端设备都已知的序列或标识对控制信息的CRC加扰。
组播方式：组播方式和广播发送相似，作为发送端的终端设备采用广播的模式进行数据发送，一组终端设备均能解析SCI和/或SSCH。一种情况下，组播的发送端和接收端是相互已知的，并且可以获得相应的组标识。另一情况，组播的发送端无法获知哪些终端设备会接收所发送的组播数据，但可以根据一些信息来限定一些终端设备来接收所发送的组播数据，例如，在距离发送端一定距离范围内的终端设备可以接收所发送的组播数据。
单播方式：单播方式是一个终端设备向另外一个终端设备发送数据，其它终端设备不需要或者不能够解析该数据。
4)侧行链路(sidelink)，是指终端装置和终端装置之间的链路。上行链路是指终端装置向网络装置发送信息的链路，下行链路是指终端装置接收来自网络装置信息的链路。
5)本申请实施例中的术语“系统”和“网络”可被互换使用。“至少一个”是指一个或者多个，“多个”是指两个或两个以上。“和/或”，描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B的情况，其中A,B可以是单数或者复数。字符“/”一般表示前后关联对象是一种“或”的关系。“以下至少一项(个)”或其类似表达，是指的这些项中的任意组合，包括单项(个)或复数项(个)的任意组合。例如，a,b,或c中的至少一项(个)，可以表示：a,b,c,a-b,a-c,b-c,或a-b-c，其中a,b,c可以是单个，也可以是多个。
以及，除非有相反的说明，本申请实施例提及“第一”、“第二”等序数词是用于对多个对象进行区分，不用于限定多个对象的顺序、时序、优先级或者重要程度。例如，第一功率控制因子和第二功率控制因子，只是为了区分不同的功率控制因子， 而并不一定是表示这两种功率控制因子的内容、优先级或者重要程度等的不同。
本申请实施例所涉及的传输控制信息的方法、装置和系统可以用于V2X，车联网，网联车，智能网联车，智能驾驶，辅助驾驶以及设备到设备通信等直连通信领域。
下面结合具体例子，以第一终端装置、第二终端装置以及网络装置为例，更加详细地描述本申请的实施例。
如图6所示，第一终端装置包括收发单元601、处理单元602。如图7所示，第二终端装置包括收发单元701、处理单元702。
当第一终端装置、第二终端装置为终端设备或者用户设备时，收发单元601、收发单元701在发送信息时可以为发送单元或发射器，收发单元601、收发单元701在接收信息时可以为接收单元或接收器，收发单元可以为收发器，此收发器、发射器或接收器可以为射频电路，当第一、第二终端装置包含存储单元时，该存储单元用于存储计算机指令，该处理器与存储器通信连接，处理器执行存储器存储的计算机指令，使第一终端装置、第二终端装置执行图2实施例涉及的方法。其中，处理器可以是一个通用中央处理器(CPU)，微处理器，特定应用集成电路(Application Specific Intergrated Circuit，ASIC)。
当第一终端装置、第二终端装置为芯片时，收发单元601、收发单元701可以是输入和/或输出接口、管脚或电路等。该处理单元可执行存储单元存储的计算机执行指令，以使该第一终端装置、第二终端装置内的芯片执行图2所涉及的方法。可选地，所述存储单元为所述芯片内的存储单元，如寄存器、缓存等，所述存储单元还可以是所述终端内的位于所述芯片外部的存储单元，如只读存储器(Read Only Memory，ROM)或可存储静态信息和指令的其他类型的静态存储设备，随机存取存储器(Random Access Memory，RAM)等。

可以携带在网络装置配置的RRC信息中，例如，在资源池配置信息中，或者采用预配置的方式告知第一终端装置，第一终端装置根据上述信息中的至少一种确定时间窗参数。在网络覆盖范围下，网络装置通过系统消息块(System Information Block，简称SIB)、小区级(cell-specific)的无线资源控制(Radio Resource Control，简称RRC)信令或者终端用户级(UE-specific)RRC信令配置本小区内终端装置的侧行链路(Sidelink，简称SL)资源池(Resource Pool)信息。在非网络覆盖范围下，用户端(UE)使用设备出厂预配置的资源池(Resource Pool)信息。资源池(Resource Pool)信息用于指示资源池。用户端(UE)在资源池内和其他UE进行侧行通信，包括单播、组播和广播通信。在时域上，包括一个或多个时间单元，时间单元可以为一个符号(symbol)、若干个符号、一个时隙、一个子帧等，所述一个或多个时间单元可以是在物理时间上连续的，也可以是离散的；在频域上，包括一个或多个频域单元，频域单元可以是一个子信道(sub channel)，一个RB或若干个RB，其中一个子信道由一个或多个资源块(resource block，简称RB)组成。
第一信道是第一终端装置与第二终端装置进行通信的侧行信道，第一终端装置根据第一信道的质量确定传输参数K m，可以避免固定重传次数导致的资源利用效率低下的问题。确定传输参数K m即确定在时间窗中传输的

为固定值的情况下，信道条件越好，需要的重传TB个数就越少，相应的新传TB的数量可以增加，即传输参数K m可以取较大的数值；当信道条件较差时，需要重传的TB的数量较多，相应初传的 TB个数减少，即传输参数K m需要取较小的数值，因此也可以把传输参数叫做新鲜因子(Freshness Factor)，

另外一种情况，如果业务可靠性要求很高，在结合其他参数情况下，例如，测量某参考信号的RSRP(Reference Signal Receiving Power，参考信号接收功率)值很高，K m取值越小也可以表征业务可靠性越高。
第一参数是第一终端装置根据来自所述第二终端装置的参考信号、所述第一信道的信道繁忙率、所述第一信道的信道占有率中的至少一种确定的。第一参数用于指示第一信道的信道质量，通过信道侦听或者信道测量的方式确定。第一终端装置接收第二终端装置的参考信号(RS，reference signal),例如解调参考信号(DMRS,Demodulation RS)，信道状态信息参考信号(CSI-RS,channel state information RS)等，第一终端装置测量接收所述RS的RSRP，第一参数为RSRP，第一终端装置根据RSRP及RSRP的门限阀值，或RSRP以及RSRP范围的对应区间确定传输参数K m。如表1所示，第一参数为参考信号接收功率，当参考信号接收功率小于数值A时，第一终端装置确定传输参数K m＝K 1，当参考信号接收功率处于区间3时，即大于数值B小于等于数值C时，第一终端装置确定传输参数K m＝K 3，表1中的对应关系可以是预定义的或者网络装置配置的。第一参数也可以是第一终端装置侦听到的信道繁忙率(CBR，ChannelBusy Ratio)或信道占有率(CR，Channel Occupancy Ratio)，其中CBR和CR通3GGP标准定义的CBR和CR相同：CBR表示，第一终端装置在一段时间内对整个SL资源池内测量所有子信道的RSSI(Received Signal Strength Indication，接收的信号强度指示)，所有RSSI测量值高于配置的或预配置的门限阀值的子信道数量跟总子信道数量的比值，用于反应该资源池内信道被使用的情况：CR表示在一段时间内，第一终端装置自己所占用的或被分配占用的用于传输侧行信息的子信道数量跟总子信道数量的比值，用于反应第一终端装置自身传输所占用信道的情况。第一终端装置根据第一参数(即CBR和/或CR)，以及预先定义/预配置/配置的的门限阈值确定传输参数K m。可选的，第一参数还可以是业务优先级，用于体现第一终端所发送的数据的服务质量(Quality of Service，QoS)。此外传输参数K m还可以是随机确定的一个参数。

当时间窗参数及传输参数均为第一终端装置确定的，第一终端装置在至少一个侧行信息中携带时间窗参数及传输参数，具体的可以承载在SCI中，当SCI为两级格式时，可以承载在一级SCI或者二级SCI中，同时第一终端装置可以在每个侧行信息中均携带时间窗参数及传输参数，也可以在某些侧行信息中携带时间窗参数及传输参数，例如，周期性地携带参数。时间窗参数及传输参数也可以携带在PC5-RRC中，即侧行数据信道内，周期性或者半静态地告知第二终端装置时间窗参数及传输参数，使得参数通知方式较为灵活。

即上一个时间窗中的5个TB与当前时间窗中的5个TB相同，可以进行合并处理。且上一个时间窗是在第n-n 1个时间单元上确定的标识为m-1的时间窗，时间单元可以为时隙，两个逻辑上相邻的时间窗的实际物理时间间隔为n 1个时隙，例如相隔10个时隙。同理，第m个传输窗与第m+1个传输窗、与第m+2个传输窗之间的实际物理时间间隔为n 2、n 3个时间单元。第m+1个传输窗、第m+2个传输窗中的TB的传输也可以是不连续的。当时间窗参数为预配置或网络装置配置的，例如第一终端装置根据资源池配置信息确定W m＝5，则资源池内所有传输窗均为5个时隙，如图3中。该6个传输窗中均传输5个TB。第一终端装置根据当前信道条件确定在W m内的K m＝0，即W m的全部TB均为W m-1窗内传输的TB的重传，即两个传输窗内的TB均为T 1、T 2、T 3、T 4、T 5。第一终端装置根据n+n 4个时间单元的第一信道状态确定第m+3个时间窗即时间窗W m+3对应的K m+3＝2，则在W m+3中的前W m+3-K m+3＝5-2＝3个TB均为W m+2窗内传输的TB的重传，即标识为m+3的时间窗中的前3个TB是标识为m+2的时间窗中后3个TB的重传，且位置关系是对应的，在标识为m+2的时间窗中最后传输的T 8在标识为m+3的时间窗的3个重传TB中仍然为最后一个，即T 6、T 7、T 8在初传和重传中的时间顺序并不改变，因此第二终端装置可对标识为m+2传输窗内T 6、T 7、T 8以及标识为m+3传输窗内T 6、T 7、T 8进行合并处理。例如，进行合并译码来获得更高的传输可靠性。图3中各个时间窗内的时间单元相同，实际中不同时间窗的W可以不同，例如

第二终端装置根据从第一信道上接收到的至少一个时间窗的至少一个侧行信息衡量第一信道的信道质量或者侧行信息接收质量。第二终端装置确定一个基于业务QoS需求的安全区间和阀值。根据第一信道上接收的侧行信息计算第二参数，可选的，所述第二参数为信干噪比(SINR，Signal to Nosie Ratio)、误检率(False detection rate)、误块率(BLER，block error rate)、参考信号接收功率(RSRP，Reference Signal Receiving Power)或其他可以衡量信道质量或数据接收质量的参数。参与计算第二参数的侧行数据可以是时间窗

个侧行信息共同来计算第二参数。第二参数的计算还可以依据多个时间窗内接收的若干个侧行数据来计算，例如对多个时间窗内的衡量信道质量或数据接收质量的参数进行平均、累加等统计。第二终端装置根据不同QoS业务的需求对应定义不同的第一阈值即门限阀值(Threshold)，并根据门限阀值设置相应的安全边界(Safety Margin)，在门限阀值和安全边界之间的数值定义为安全区间(Safety region)。如图5所示，纵坐标代表第二参数的取值，横坐标代表时间，门限阈值与安全边界之间的区间称为安全区间，黑色折线是第二参数随时间的取值情况，以RSRP为例，第二终端参数根据接收到的侧行信息计算RSRP，并与预先定义的或网络装置确定第一阈值、安全边界进行比较。当第二参数的取值落在安全边界与门限阈值区间之内时，可认为目前的参数如时间窗参数与传输参数暂时满足要求，不需要进行调整，若第二参数的数值低于安全区间或者超出第一阈值，目前的参数不满足传输需要，要对时间窗参数或者传输参数或两者进行调整。第二终端装置根据第二参数与门限阈值即安全边界确定对时间窗参数或传输参数的调整进行指示的第一指示信息。
如果第二终端装置在一段时间T1内的第二参数，例如T1内的RSRP平均值超过门限阀值，向第一终端装置进行高层反馈，反馈手段例如PC5-RRC反馈或者AS层(Access Layer)的反馈，确定第一指示信息为ΔW′ m和/或ΔK′ m，第一指示信息用于第一终端装置在下一次时间窗传输时下调当前的W和/或K值。
如果第二终端装置在一段时间T1内的第二参数，例如T1内的RSRP平均值在安全区间内，向第一终端装置进行高层反馈，反馈手段例如PC5-RRC反馈或者AS层(Access Layer)的反馈，确定第一指示信息为ΔW′ m＝0和/或ΔK′ m＝0，第一指示信息 用于第一终端装置在下一次时间窗传输时保持当前的W和/或K值。
如果第二终端装置在一段时间T1内的第二参数，例如T1内的RSRP平均值没有达到安全边界，向第一终端装置进行高层反馈，反馈手段例如PC5-RRC反馈或者AS层(Access Layer)的反馈，确定第一指示信息为ΔW′ m和/或ΔK′ m，第一指示信息用于第一终端装置在下一次时间窗传输时提高当前的W和/或K值。
通过避免物理层的闭环反馈(例如，HARQ-ACK反馈，CSI反馈)，避免对反馈资源的消耗，提升了系统容量，也降低了反馈导致的时延问题。同时根据适应性的W和/或K的调整，避免忙重传的不必要多次重传而导致的资源浪费，提升了系统频谱利用率，也同时降低了不必要重传而导致的对其他用户的干扰。
