Description

车联网中的V2X通信方法及装置 技术领域
本发明涉及通信领域，具体而言，涉及一种车联网中的V2X通信方法及装置。
背景技术
车联网是指按照约定的通信协议和数据交互标准，在车-X(X：车、路、行人及互联网等)之间，进行无线通讯和信息交换的大系统网络。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，简称为V2V)，车辆与路边设备之间通信(Vehicle to Infrastructure，简称为V2I)，以及车辆与行人之间通信(Vehicle to Pedestrian，简称为V2P)，统称为V2X通信。
目前，第三代移动通讯伙伴计划(3rd Generation Partnership Project，简称为3GPP)组织已经开始基于长期演进(Long Term Evolution，简称为LTE)的V2X通信研究，其中，基于设备到设备(Device-to-Device，简称为D2D)的通信方法就是V2X标准实现的方式之一。D2D是指有业务传输的用户设备(User Equipment，简称为UE)之间，业务数据不经过基站和核心网的转发，直接由源用户设备通过空口传输给目标用户设备。基于LTE蜂窝通信网络链路的通信方法是实现V2X标准实现的另一方式之一，这种方式下基站和/或中继会参与V2X通信，在上行链路和/或下行链路传输V2X信号。
V2P通信属于V2X通信范畴，主要是保护行人或易受伤害对象避免交通事故伤害或潜在危险，通常手持终端在移动中没有外部电源持续供电，需要有节省功耗的通信方法尽量延长可通信的时间，提高电池供电效率。
另一方面，手持终端用户比较集中，移动速度比较低，容易出现通信资源冲突问题，特别是在用户拥挤的场景，容易出现通信网络拥塞问题，这些问题都会影响V2P通信的可靠性。
针对相关技术中存在的车联网端到端通信的功耗效率低，以及通信资源冲突和网络拥塞的问题，目前尚未提出有效的解决方案。

具体实施方式
下文中将参考附图并结合实施例来详细说明本发明。需要说明的是，在不冲突的情况下，本申请中的实施例及实施例中的特征可以相互组合。
需要说明的是，本发明的说明书和权利要求书及上述附图中的术语“第一”、“第二”等是用于区别类似的对象，而不必用于描述特定的顺序或先后次序。
本发明中所述的技术可以适用于蜂窝无线通信系统或网络。常见的蜂窝无线通信系统可以基于码分多址(Code Division Multiplexing Access，简称为CDMA)技术、频分多址(Frequency Division Multiplexing Access，简称为FDMA)技术、正交频分多址(Orthogonal-FDMA，简称为OFDMA)技术、单载波频分多址(Single Carrier-FDMA，简称为SC-FDMA)技术，等。例如，3GPP LTE/LTE-A(LTE-Advanced，高级长期演进)蜂窝通信系统下行链路(或称为前向链路)基于OFDMA技术，上行链路(或称为反向链路)基于SC-FDMA多址技术。
在OFDMA/SC-FDMA系统中，用于通信的无线资源(Radio Resource)是时-频两维的形式。例如，对于LTE/LTE-A系统来说，上行和下行链路的通信资源在时间方向上都是以无线帧(radio frame)为单位划分，每个无线帧(radio frame)长度为10ms，包含10个长度为1ms的子帧(sub-frame)，每个子帧包括长度为0.5ms的两个时隙(slot)，如图1所示，图1是相关技术中无线资源帧结构的示意图。而根据循环前缀(Cyclic Prefix，简称为CP)的配置不同，每个时隙可以包括6个或7个OFDM或SC-FDM符号。
在频率方向，资源以子载波(subcarrier)为单位划分，具体在通信中，频域资源分配的最小单位是资源块(Resource Block，简称为RB)，对应物理资源的一个物理资源块(Physical RB，简称为PRB)。一个PRB在频域包含12个子载波(sub-carrier)，对应于时域的一个时隙(slot)。每个OFDM/SC-FDM符号上对应一个子载波的资源称为资源单元(Resource Element，简称为RE)。如图2所示，图2是相关技术中无线资源结构的示意图。

步骤S402，确定可用于发送P2V信号发送资源池，和V2X信号接收资源池；
步骤S404，选择无线资源，发送P2V信号；
步骤S406，接收V2X信号。
需要说明的是，上述P2V信号是专指V2P通信中行人手持终端(本发明中可以简称为P-UE)发送，车载终端(本发明中可以简称为V-UE)接收的信号。V2P通信中V-UE发送，P-UE接收的信号在本发明中可以称为V2X信号。
实施例一
一种V2X通信方法，UE根据资源配置参数确定可用于V2X通信的资源池，包括发送资源池和/或接收资源池，发送资源池与接收资源池相互正交或重叠。和/或，上述资源配置参数进一步包括发送资源池周期和/或接收资源池周期，和/或，发送资源池有效子帧和/或接收资源池有效子帧，和/或，发送资源池子帧范围和/或接收资源池子帧范围，和/或，发送资源块RB范围和/或接收资源池资源块RB范围，和/或，发送时间窗和/或接收时间窗。
确定可用于V2X通信的资源池的方法，至少包括：基于UE分组的方法，不同组的UE根据所在分组对应的资源配置参数确定资源池。具体包括以下至少之一：基于终端类型分组，相同类型的UE使用同一个资源池或相同的资源池分组，包括：同一种类型的UE使用一个资源池或资源池分组，或多个不同类型的UE使用一个资源池或资源池分组。其中，不同类型的终端包括：手持终端、车载终端、路边设备(Road Side Unit，简称为RSU)；或者，基于UE的地理位置和/或区域范围分组，地理位置不同或处于不同区域范围内的UE使用不同的无线资源池或资源池分组；或者，基于UE业务属性分组，不同的业务类型或者发送和/或接收不同类型业务的UE使用不同的资源池或资源池分组。
例如，在V2P通信中，V-UE和P-UE使用不同的发送资源池和/或接收资源池，资源池周期相同或者不同。对于P-UE，发送资源池与接收资源池正交，接收资源池为V-UE的发送资源池或V-UE的发送资源池的一部分；对于V-UE，发送资源池与接收资源池正交。一个例子如图5所示，图5是根据本发明实施例的基于终端类型分组确定资源集合的示意图，在100ms资源池周期内，P-UE与V-UE的发送资源池正交，P-UE的接收资源池对应V-UE的发送资源池，V-UE的接收资源池包含P-UE的发送资源池。需要说明的是，本实施例中对资源池的形式并不作限定，发送资源池和/或接收资源池可以是集中式的或分布式的，在时域和/或频域可以是连续的或离散的。
或者，基于UE的地理位置和/或区域范围分组，例如，在V2P通信中，根据车道信息分组，处在车道内的P-UE一组，车道外的P-UE一组；或者处在不同车道上的P-UE分别为不同的组。不同组的UE使用不同的发送资源池或者多个不同组的UE使用同一资源池或资源池分组。如图6所示，图6是根据本发明实施例的基于地理位置和/或区域范围分组确定资源集合的示意图，其中，500为处于车道内P-UE的发送资源池，501为车道外P-UE的发送资源池。不同组的P-UE使用的发送资源池正交，可以是时分方式和/或频分方式。
或者，基于UE业务类型分组，例如，在V2X通信中，V-UE在专用资源池接收P-UE发送的P2V信号，与接收其它V2X信号的资源池不同。
例如，周期性数据与事件触发型数据使用不同的资源池或资源池分组。
实施例二
一种V2X通信方法，UE选择发送资源的方法包括：基于UE分组的方法选择发送资源，对于不同组的UE选择不同的发送资源发送V2X通信信号。
UE分组方法包括：基于UE的地理位置和/或区域范围分组，在地理位置上不同或处于不同区域范围的UE属于不同组。比如，在V2P通信中，根据P-UE的地理位置是否在车道内组，位置在车道内的P-UE和在车道外的P-UE分别在不同UE组，或者，在不同车道内的P-UE分别为不同的组。不同组的P-UE选择不同的资源发送P2V(Pedestrian to Vehicle，行人用户发送给车辆用户)信号，或者，基站或路边设备为不同组的UE调度不同的资源，不同的资源包括在时域选择不同的SC-FDMA子帧和/或在频域选择不同的RB。
或者，基于随机数分组，UE在0～N的范围内随机生成正整数，生成的正整数值相同的UE为相同组，不同组的UE选择不同或相同的资源，其中N的取值与UE发送V2X通信信号的周期有关。比如，在V2P通信中，假设P-UE的资源池周期为100ms，P2V信号发送周期为1s，取N＝10，P-UE在[0,10)范围生成随机正整数m，根据m值确定发送资源的偏移量，在1s周期内偏移量为m*100ms的资源池中选择资源发送P2V信号；或者，基站或路边设备为不同组的UE调度不同的资源，不同的资源包括在时域选择不同的SC-FDMA子帧和/或在频域选择不同的RB。
一种V2X通信方法，UE选择发送资源的方法还包括：基于资源冲突和/或信号拥塞选择资源。包括：确定是否发生资源冲突和/或信号拥塞，如果发送资源冲突和/或信号拥塞，则选择资源时，改变选择准则，或改变UE分组。例如，在V2P通信中，如果确定发生资源冲突，则P-UE选择的无线资源的子帧索引和/或RB索引分别加一个随机值，如果改变后的子帧索引和/或RB索引的值超出V2X资源池周期内最大子帧数和/或带宽内最大RB数，则基于最大子帧数和/或最大RB数进行取模后的值选择无线资源；或者，终端的ID值加上一个随机数之后，基于V2P无线资源池周期内的最大可用子帧数和/或带宽内最大RB数进行模运算，根据模运算结果选择无线资源；或者，UE在其它组的资源池中选择资源，比如，在车道A内的P-UE确定发送资源冲突和/或拥塞，则选择车道B的P-UE所在分组的资源发送P2V信号。
实施例三
一种V2X通信方法，终端发送V2X通信信号的方法包括：如果终端检测到V2X通信信号，则在接收到V2X通信信号之后时延最小的发送资源池周期内至少发送一次V2X通信信号；或者，在接收到V2X通信信号之后时延最小的发送资源池周期中时间窗W以内至少发送一次V2X通信信号，其中W的值不大于发送资源池周期，可以通过网络侧配置或者被预配置为固定值。如果发送资源池基于分组确定，则UE选择所属组对应的发送资源池发送V2X通信信号。其中，所述接收到V2X通信信号之后时延最小的发送资源池周期，不包括所述接收V2X通信信号所在的发送资源池和/或接收资源池。
例如，在V2P通信中，当V-UE检测到P-UE发送的P2V信号后，则在接收P2V消息之后时延最小的V2X信号发送资源池周期内，选择发送资源至少发送一次V2X消息；或者，在 时延最小的V2X信号发送资源池周期内的时间窗W以内，选择发送资源至少发送一次V2X消息。如果V-UE的发送资源池基于分组确定，则V-UE在所属组对应的资源池或者资源池周期内的时间窗W以内的V-UE所属组对应的发送资源池至少发送一次V2X信号。
或者，终端发送V2X通信信号的方法包括，如果终端能接收到其他终端发送的V2X通信信号，则发送V2X通信信号；如果连续K个资源周期没有检测到其他终端发送的V2X通信信号，则不发送V2X通信信号，或者增大V2X通信信号发送周期，其中K为正整数。
例如，在V2P通信中，如果P-UE能够接收到V-UE发送的V2X消息，则P-UE发送P2V消息；或者，P-UE发送P2V信号后，检测V2X信号，如果能接收到V2X消息，则下一个发送资源池周期发送P2V消息。又比如在V2X通信中，假设V-UE没有检测到其它终端发送的信号，则在这种场景下所述V-UE不发送V2X消息或者增大发送周期。
或者，例如在V2P通信中，如果P-UE连续K个接收资源池周期中没有检测到V-UE发送的V2X信号，比如K取1，2，4，8等，则所述P-UE终止发送P2V消息，或者增大发送P2V消息的发送周期，比如增大为原发送周期的2倍、4倍、或8倍等。
实施例四
一种V2X通信方法，终端发送V2X通信信号的方法包括：如果信号接收终端确定不同发送终端的信号之间存在资源冲突或出现信号拥塞，则所述接收终端发送指示信号，指示信号包含的指示信息包括但不限于是否发生冲突和/或发生冲突的资源位置和/或范围，或者是否发生信号拥塞和/或拥塞的程度的指示参数。发送指示信号采用随机选择资源的方式，或与发送控制和/或数据相同的资源竞争方式。承载指示信息的方法包括：使用公用数据和/或控制物理信道承载，根据数据类型和/或控制类型指示；或者，采用专用物理信道承载。
例如，在V2P通信中，如果V-UE确定接收资源发生资源冲突，则通过广播方式发送V2X信号的控制和/或数据，在V2X信号的控制和/或数据中新增类型指示参数，用于指示控制和/或数据的内容为资源冲突信息；或者，通过新定义物理信道传输指示信号，指示资源冲突信息。其中，新定义物理信道包括控制信道和/或数据传输信道。或进一步包括，资源冲突信息至少包括发生资源冲突的资源的时域SC-FDMA子帧索引和/或频域RB索引。或者，如果V-UE检测确定在接收资源池发生信号拥塞，则通过广播方式发送V2X信号的控制和/或数据，在V2X信号的控制和/或数据中新增类型指示参数，用于指示控制和/或数据的内容为拥塞信息。或者，通过新定义物理信道传输指示信号，指示拥塞信息。其中，新定义物理信道包括控制信道和/或数据传输信道。或进一步包括，拥塞信息至少包括发生信号拥塞的资源时域范围和/或资源频域范围，和/或拥塞的程度。V-UE随机选择资源发送指示信号，或者采用控制和/或数据发送的资源竞争方法，比如通过信号检测，或者能量感知。
实施例五
一种V2X通信方法，终端发送V2X通信信号的方法包括：基于资源冲突或信号拥塞确定V2X通信信号的发送。具体包括：
如果发生资源冲突或信号拥塞，则基于与接收终端的相对距离确定V2X通信信号的发送。例如，在V2P通信中，如果V-UE确定P-UE发送的信号发生资源冲突或出现信号拥塞，则发送资源冲突或拥塞指示信号和/或V2X信号，P-UE接收到指示信号后根据指示信息确定发生资源冲突或出现拥塞。P-UE基于与接收到的V2X信号或指示信号的发送端V-UE的相对距离确定P2V信号的发送。比如，根据门限值判断，如果所述相对距离小于门限，则发送V2P信号或者选择与上一次发送P2V信号相同的资源发送P2V信号，如果多次接收到指示信号指示相同的资源发生冲突和/或出现拥塞，比如R次，R＝2,3,4…，并且所述相对距离小于门限，则P-UE重新选择资源发送P2V信号；否则，不发送或延迟发送P2V信号和/或增大发送周期发送P2V信号，或者选择与上一次发送P2V信号不相同的资源发送P2V信号。或者，根据门限值判断，如果所述相对距离大于门限，则选择与上一次发送P2V信号相同的资源发送P2V信号，否则，选择与上一次发送P2V信号不相同的资源发送P2V信号。
或者，如果发生资源冲突或拥塞，则基于终端的地理位置和/或区域范围确定V2X通信信号的发送。例如，在V2P通信中，如果P-UE确定发生资源冲突或拥塞，则P-UE基于自己的地理位置和/或区域范围确定P2V信号的发送。比如，基于所在车道位置判断，如果P-UE在车道范围以内，则发送P2V信号或者选择与上一次发送P2V信号相同的资源发送P2V信号；否则，不发送或延迟发送P2V信号和/或增大发送周期发送P2V信号，或者选择与上一次发送P2V信号不相同的资源发送P2V信号。或者，根据P-UE的地理位置和/或区域范围分组，比如，基于离道路中心的远近，不同的P-UE分成不同组，如图7所示，图7是根据本发明实施例的基于地理位置确定V2X通信信号发送的示意图，分成I、II、III三个组，组I内的P-UE发送P2V信号或者则与选择上一次发送P2V信号相同的资源发送P2V信号；组II内的P-UE延迟发送P2V信号和/或增大发送周期发送P2V信号，或者选择与上一次发送P2V信号不相同的资源发送P2V信号；组III内的P-UE不发送或延迟发送P2V信号和/或增大发送周期发送P2V信号，或者选择与上一次发送P2V信号不相同的资源发送P2V信号。或者，三个不同组的UE分别选择不同发送周期和/或不同的延迟发送P2V信号。
或者，如果发生资源冲突或拥塞，则基于终端的相对移动方向确定V2X通信信号的发送。例如，V2P通信中，如果P-UE确定发生资源冲突或拥塞，则P-UE根据接收端V-UE的移动方向确定P2V信号发送。如果V-UE的移动方向为正向，即V-UE与P-UE的距离越来越近，则P-UE发送P2V信号或者选择与上一次发送P2V信号相同的资源发送P2V信号；否则，不发送或延迟发送P2V信号和/或增大发送周期发送P2V信号，或者选择与上一次发送P2V信号不相同的资源发送P2V信号。
或者，如果发生资源冲突或拥塞，则基于终端的标识ID值确定V2X通信信号的发送。例如，V2P通信中，如果P-UE确定发生资源冲突或拥塞，则P-UE根据终端ID值判断，如果ID值为奇数，则P-UE选择索引为奇数的子帧发送P2V信号，如果ID值为偶数，则P-UE选择索引为偶数的子帧发送P2V信号。或者，ID值为奇数的P-UE基于发送周期T选择偏移量1发送P2V信号，ID值为偶数的P-UE基于发送周期T选择偏移量2发送P2V信号。其中，偏移量1和偏移量2为相对资源周期的起始位置的偏移，并且偏移量1与偏移量2不等。
或者，如果发生资源冲突或拥塞，则基于不同周期发送V2X通信信号。确认发生资源冲突或拥塞的UE改变发送周期发送信号，比如增大发送周期；如果确认没有发生资源冲突或拥塞，UE也改变发送周期，比如减小发送周期。例如，V2P通信中，如果P-UE确认发生资源冲突或拥塞，则增大发送周期发送P2V信号，如果仍然存在资源冲突或拥塞，则继续增大发送周期。当连续多次没有资源冲突或拥塞时，则P-UE减小P2V信号的发送周期。
或者，如果发生资源冲突或拥塞，则基于随机延迟发送V2X通信信号，终端通过生成随机数X，延迟X个资源周期或发送资源周期或者时间上延迟X发送V2X通信信号。例如，在V2P通信中，如果V-UE确定发生资源冲突或拥塞，则生成随机数X，比如生成X＝3，并延迟X＝3ms之后发送P2V信号。或者，比如在V2P通信中，如果P-UE确定发生资源冲突或拥塞，则生成随机数X，比如生成X＝5，并延迟5倍发送资源周期之后发送P2V信号。
实施例六
一种V2X通信方法，基于UE分组确定V2X通信信号的发送，包括：如果基站和/或中继设备参与终端到终端的通信，则基站和/或中继设备基于UE分组，通过定时器C将同一个组的UE在N个发送资源池周期或V2X信号发送周期内发送的数据组成一个数据包发送，N为正整数，可以配置和/或预定义；或者对每个组中只选择L个UE的数据发送，L为正整数。其中UE分组的方法包括：基于UE的相对距离和/或UE移动的速度和/或加速度。例如，在基于LTE Uu链路的V2P通信，如图8所示，图8是根据本发明实施例的基于UE分组确定V2X通信信号发送的示意图。P-UE通过上行链路发送数据到基站，基站再通过下行链路广播P-UE的数据。如果P-UE1、P-UE2和P-UE3相互之间的相对距离小于判决门限Y，Y的值可以为预定义，则基站将所述三个P-UE判断为一组，为组I。那么基站在广播P-UE的数据时，将组I的三个P-UE的数据组成一个数据包发送，通过定时器C的值N，比如预定义N＝1，则每1个发送资源池周期或V2P信号发送周期发送1次组成之后的数据包；或者，基于判断准则选择其中一个P-UE的数据广播，判断准则比如有移动速度最高和/或加速度最大和/或距离附近的V-UE最近等。或者，基站和/或中继设备基于UE分组，只调度同一组UE中的一个或多个UE发送V2X通信信号，或者调度同一组UE中的一个或多个UE发送V2X通信信号，并增大发送周期和/或降低发送功率。其中UE分组的方法包括：基于UE的相对距离和/或UE移动的速度和/或加速度。或者，基站或中继设备根据发送UE的有效通信范围内是否有其他UE存在，确定是否在下行链路广播UE发送的V2X信号。比如，如果确定在发送UE有效通信范围内没有其他UE，则不在下行链路广播所述UE发送的V2X信号。
或者，基于UE分组确定V2X通信信号的发送，包括：如果UE检测到同组其他UE发送的信号，则UE不发送信号或降低功率发送，比如降低到常规发送功率的1/K或为预定义的固定值，K为正整数。或者进一步包括，如果UE连续Q次没有检测到同组其他UE的V2X通信信号，则发送V2X通信信号，其中Q为正整数。其中UE分组的方法至少包括：基于UE的相对距离和/或相对位移和/或UE移动的速度和/或加速度。例如，在V2P通信中，如果P-UE检测到其他P-UE的P2V信号，并确定其他P-UE的与自己的相对距离和/或相对位移满足判断门限，比如小于门限值，和/或其他P-UE移动的速度和/或加速度相对自己移动的速度和/或 加速度的差值满足判断门限，比如小于门限值，则所述P-UE不发送P2V信号，或降低功率发送，比如降低到常规发送功率的1/2，1/4等。或者进一步，如果P-UE连续Q(比如Q＝1,2,3…，)次检测不到其他P-UE的P2V信号，或者检测到P2V信号，但相对距离和/或相对位移，和/或移动的速度和/或加速度不能满足门限判断，比如不小于门限值，则所述P-UE发送P2V信号。
实施例七
一种V2X通信方法，终端接收V2X通信信号的方法，包括：发送V2X通信信号之后在接收资源池或者接收资源池的子集中接收V2X通信信号；或者进一步包括，在部分接收资源池周期接收V2X通信信号。例如，在V2P通信中，P-UE只在发送了P2V信号之后的接收资源池接收V2P信号，如图9所示，图9是根据本发明实施例的接收V2X通信信号的示意图，P-UE按照1s的发送周期在800和802中发送P2V消息，并在接收资源池801和803中接收V2P消息。或者，在资源池801和803的部分资源接收V2P消息，部分资源包括时域上的子集和/或频域上的子集。又例如，在V2P通信中，V-UE按照100ms的周期发送V2X消息，而P-UE只是在部分的接收资源池周期接收V2X消息，比如，按照1s的周期检测接收V2X消息。
通过以上的实施方式的描述，本领域的技术人员可以清楚地了解到根据上述实施例的方法可借助软件加必需的通用硬件平台的方式来实现，当然也可以通过硬件，但很多情况下前者是更佳的实施方式。基于这样的理解，本发明的技术方案本质上或者说对现有技术做出贡献的部分可以以软件产品的形式体现出来，该计算机软件产品存储在一个存储介质(如ROM/RAM、磁碟、光盘)中，包括若干指令用以使得一台终端设备(可以是手机，计算机，服务器，或者网络设备等)执行本发明各个实施例所述的方法。
