具体实施方式
下文中将结合附图对本申请的实施例进行详细说明。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任意组合。
在附图的流程图示出的步骤可以在诸如一组计算机可执行指令的计算机系统中执行。并且，虽然在流程图中示出了逻辑顺序，但是在某些情况下，可以以不同于此处的顺序执行所示出或描述的步骤。
本申请的技术方案可以应用于多种通信系统，例如：全球移动通讯(Global System of Mobile communication，GSM)系统、码分多址(Code Division Multiple Access，CDMA)系统、宽带码分多址(Wideband Code Division Multiple Access，WCDMA)系统、通用分组无线业务(General Packet Radio Service，GPRS)、长期演进(Long Term Evolution，LTE)系统、LIE-A(Advanced long term evolution，先进的长期演进)系统、通用移动通信系统(Universal Mobile Telecommunication System，UMTS)、以及5G系统等，本申请实施例并不限定。在本申请中以5G系统为例进行说明。
在车对外界的信息交换(vehicle to everything，V2X)技术中，包含半覆盖场景的应用，即相邻的UE包含覆盖内UE和覆盖外UE，如图1所示，覆盖内UE在基站的覆盖范围内， 覆盖外UE在基站的覆盖范围外，覆盖内UE和覆盖外UE之间进行边链路通信。覆盖内UE和覆盖外UE可以工作在不同载波上，比如覆盖内UE在共享载波，覆盖外UE在专用载波上；也可以在相同载波上，比如都在共享载波上。
当覆盖内UE与覆盖外UE工作在相同载波时，需要保持在该载波上的帧结构一致，才能正确接收V2X消息，实现V2X通信。对于覆盖内UE与覆盖外UE都工作在共享载波的情况，为了不影响蜂窝通信系统在Uu链路的通信，覆盖外UE必须保持与覆盖内UE相同的帧结构，以实现与覆盖内UE的V2X通信。
首先，需要说明的是，本申请实施例中，基站可以是能和用户终端进行通信的设备。基站可以是任意一种具有无线收发功能的设备。包括但不限于：基站NodeB、演进型基站eNodeB、5G通信系统中的基站、未来通信系统中的基站、WiFi系统中的接入节点、无线中继节点、无线回传节点等。基站还可以是云无线接入网络(cloud radio access network，CRAN)场景下的无线控制器；基站还可以是小站，传输节点(transmission reference point，TRP)等，本申请实施例并不限定。
本申请实施例中，用户终端是一种具有无线收发功能的设备可以部署在陆地上，包括室内或室外、手持、穿戴或车载；也可以部署在水面上(如轮船等)；还可以部署在空中(例如飞机、气球和卫星上等)。所述用户终端可以是手机(mobile phone)、平板电脑(Pad)、带无线收发功能的电脑、虚拟现实(Virtual Reality，VR)终端、增强现实(Augmented Reality，AR)终端、工业控制(industrial control)中的无线终端、无人驾驶(self driving)中的无线终端、远程医疗(remote medical)中的无线终端、智能电网(smart grid)中的无线终端、运输安全(transportation safety)中的无线终端、智慧城市(smart city)中的无线终端、智慧家庭(smart home)中的无线终端等等。本申请的实施例对应用场景不做限定。用户终端有时也可以称为终端、接入终端、UE单元、UE站、移动站、移动台、远方站、远程终端、移动设备、UE终端、无线通信设备、UE代理或UE装置等。本申请实施例并不限定。
在长期演进(Long Term Evolution，LTE)V2X中，时分双工上行链路下行链路(TDD UL-DL)配置信息包含在物理边链路广播信道(Physical边链路Broadcast Channel，PSBCH)中，用于指示共享载波上配置的时分双工(Time Division Duplex)，TDD)系统上下行帧结构，LTE系统中总共支持7种TDD UL-DL配置信息，在PSBCH中通过3比特(bits)可以指示出覆盖内的配置值。
在NR系统中，帧结构配置包括半静态Cell-specific帧结构配置(tdd-UL-DL-Configuration Common)，半静态UE-specific帧结构配置(tdd-UL-DL-Configuration Dedicated)，动态Group-commom帧结构配置(DCI format 2_0)。在NR V2X中，PSBCH中只指示半静态Cell-specific帧结构配置信息，即tdd-UL-DL-ConfigurationCommon的内容。tdd-UL-DL-ConfigurationCommon的配置支持单个DL-UL pattern配置(pattern1)和双DL-UL pattern配置(pattern1和pattern2)，在配置的DL-UL pattern中可以包含DL时隙，Unknown时隙和UL时隙中的一种、两种或三种。如果包含的时隙超过一种，则严格按照DL、Unknown以及UL的顺序配置，Unknown时隙的第一个时隙可以包含DL符号，最后一个时隙可以包含UL符号，如附图2所示。
相关技术中，在PSBCH中，指示了NR的tdd-UL-DL-Configuration Common配置信息， 包含单个DL-UL pattern配置还是双DL-UL pattern配置，和单周期配置或双周期配置所对应的周期值(分别根据表1和表2确定)，以及tdd-UL-DL-Configuration Common配置中包含的可用于边链接资源映射的UL时隙数。

在一个示例实施例中，在PSBCH中，通过第一指示和第二指示来联合指示NR V2X工作在与LTE Uu共享的频段，通过LTE Uu控制NR V2X，或者说，通过第一指示和第二指示来联合指示PSBCH中包含的域指示了LTE的上行下行配置Uplink-downlink configuration信息，和/或LTE的特殊子帧配置Special subframe configuration信息。
比如，用指示tdd-UL-DL-ConfigurationCommon中单双周期配置的1比特a 0和指示DL-UL pattern配置周期值的4比特a 1a 2a 3a 4联合指示NR V2X工作在LTE Uu频段，由LTE Uu控制，或者说PSBCH中包含的域指示了LTE的配置信息，比如上行下行配置Uplink-downlink configuration信息和/或特殊子帧配置Special subframe configuration信息。

在一个示例实施例中，在PSBCH中，通过3比特指示LTE的上行-下行配置(Uplink-downlink configuration)信息。例如，用PSBCH中指示tdd-UL-DL-ConfigurationCommon配置中包含的可用于sidelink资源映射的UL slot数的7比特中的3比特来指示。比如，用a 5a 6a 7指示LTE中的Uplink-downlink configuration的值，其 范围为0～6。
在一个示例实施例中，比特串a 5a 6a 7为000指示LTE中Uplink-downlink configuration索引为0的配置，即表3中Uplink-downlink configuration值为0的配置信息，比特串a 5 a 6 a 7为001指示LTE中Uplink-downlink configuration索引为1的配置，即表3中Uplink-downlink configuration值为1的配置信息，依次类推，比特串a 5 a 6 a 7为110指示LTE中Uplink-downlink configuration索引为6的配置，即表3中Uplink-downlink configuration值为6的配置信息。
在一个示例实施例中，在PSBCH中，通过4比特指示LTE的特殊子帧配置信息。例如，用PSBCH中指示tdd-UL-DL-ConfigurationCommon配置中包含的可用于sidelink资源映射的UL slot数的7比特中的4比特来指示。比如，用a 8a 9a 10a 11指示LTE中的特殊子帧配置Special subframe configuration的值，其范围为0～10。
在一个示例实施例中，比特串a 8 a 9 a 10 a 11为0000指示LTE中Special subframe configuration索引为0的配置，即表4中Special subframe configuration值为0的配置信息，比特串a 8 a 9 a 10 a 11为0001指示LTE中Special subframe configuration索引为1的配置，即表4中Special subframe configuration值为1的配置信息，依次类推，比特串a 8 a 9 a 10 a 11为1010指示LTE中Special subframe configuration索引为10的配置，即表4中Special subframe configuration值为10的配置信息。
在一个示例实施例中，在PSBCH中，通过第一指示信息联合第二指示信息来指示LTE的TDD帧结构信息，所述TDD帧结构信息包括如下一个或多个：TDD上行下行配置信息，特殊子帧配置信息，子载波间隔SCS，无线帧结构类型，无线帧结构配置周期，无线帧结构中上下行切换周期。
例如，第一指示信息为PSBCH中用来指示tdd-UL-DL-ConfigurationCommon中单双周期配置的1个比特a 0指示的内容，比如，a 0的指示值为0。
第二指示信息包括：第一帧结构指示信息和/或第二帧结构指示信息，
例如，第一帧结构指示信息承载于PSBCH中指示DL-UL pattern配置周期值的4比特a 1 a 2 a 3 a 4，a 1 a 2 a 3 a 4的值指示了LTE的上行下行配置信息。
比如，比特串a 1 a 2 a 3 a 4＝1001指示LTE中上行下行配置索引为0的配置信息，即表3中上行下行配置Uplink-downlink configuration值为0的配置信息；比特串a 1 a 2 a 3 a 4＝1010指示LTE中上行下行配置索引为1的配置信息，即表3中上行下行配置Uplink-downlink configuration值为1的配置信息；以此类推，比特串a 1a 2a 3a 4＝1111指示LTE中上行下行配置索引为6的配置信息，即表3中上行下行配置Uplink-downlink configuration值为6的配置信息。
例如，第二帧结构指示信息承载于PSBCH中指示tdd-UL-DL-ConfigurationCommon配置中包含的可用于边链路资源映射的UL时隙数的7比特或7比特中的部分(比如4比特)，指示的是LTE定义的特殊子帧配置Special subframe configuration信息。比如，用比特串a 5 a 6 a 7a 8为0000指示LTE中特殊子帧配置索引为0的配置，即表4中特殊子帧配置Special subframe configuration值为0的配置信息；比特串a 5 a 6 a 7a 8为0001指示LTE中特殊子帧配置索引为1的配置，即表4中特殊子帧配置Special subframe configuration值为1的配置信息；依次类推， 比特串a 5 a 6 a 7a 8为1010指示LTE中特殊子帧配置索引为10的配置，即表4中特殊子帧配置Special subframe configuration值为10的配置信息。
在一个示例实施例中，在PSBCH中，利用指示tdd-UL-DL-ConfigurationCommon配置中包含的可用于边链路资源映射的UL时隙数的7比特来指示LTE定义的上行下行配置信息。例如，用比特串a 5 a 6 a 7 a 8 a 9 a 10 a 11分别指示表3中Subframe number值中对应2，3，4，6，7，8，9列的值，用比特0或1对应D，S和U中的其中一个。比如，a 5 a 6 a 7 a 8 a 9 a 10 a 11＝1100110来指示表3中上行下行配置Uplink-downlink configuration值为1的配置信息，这里约定用比特1表示U，0表示D或S。
另一种实施例中，表3中Subframe number值中对应0，1，4，5列的值对于不同上行下行配置Uplink-downlink configuration值都是相同的，可以按照固定值的方式确定。
在一个示例实施例中，在PSBCH中，指示LTE的Uplink-downlink configuration信息。比如，将表3中Subframe number的信息按照相关技术中的PSBCH指示机制中双周期的指示方式进行指示。
例如，对表3中上行下行配置Uplink-downlink configuration值为3的配置信息按照双周期方式指示，双周期p1和p2都为5ms，PSBCH中用来指示tdd-UL-DL-ConfigurationCommon中单双周期配置的比特a 0的指示值为1，用来指示DL-UL pattern配置周期值的比特串a 1a 2a 3a 4的指示值为1110；对应双周期的pattern1和pattern2的上下行配置分别为DSUUU和DDDDD，通过PSBCH中指示tdd-UL-DL-ConfigurationCommon配置中包含的可用于sidelink资源映射的UL slot数的比特串a 5a 6a 7a 8a 9a 10a 11指示，按照表2确定指示粒度w，假设SL SCS为15kHz，则w为1。根据公式计算可确定要指示的UL时隙数为3，即比特串a 5a 6a 7a 8a 9a 10a 11的指示值为3。
在一个示例实施例中，PSBCH中，通过指示域指示无线通信所使用的子载波间隔SCS，和/或无线帧结构类型，和/或无线帧结构配置周期或无线帧结构中上下行切换周期，和/或无线帧结构配置，和/或特设子帧或时隙配置。比如，通过指示tdd-UL-DL-ConfigurationCommon中单双周期配置的比特a 0和指示DL-UL pattern配置周期值的4比特a 1a 2a 3a 4来指示上述内容。
例如，比特a 0的指示值为0，比特串a 1a 2a 3a 4＝1100指示LTE系统的无线通信系统的SCS为15kHz，无线帧结构配置周期为10ms，和/或帧结构上行下行切换周期为10ms或5ms。和/或以下至少之一的无线帧结构配置信息：LTE的帧结构类型2的7种配置，LTE的帧结构类型1配置，LTE的帧结构类型3配置。比如LTE的帧结构类型2中上行下行配置Uplink-downlink configuration的值为3的配置信息。
在一个示例实施例中，PSBCH中，预留比特中的1比特的指示信息表示PSBCH指示域包含对LTE帧结构配置信息的指示。比如，PSBCH中用来指示TDD上下行配置信息的比特串a 0～a 11包含对LTE帧结构配置信息的指示。
在一个示例实施例中，PSBCH中预留比特中的一个比特值为1表示当前PSBCH中包含了对LTE帧结构配置信息的指示。例如，比特串a 1 a 2 a 3指示了LTE的Uplink-downlink  configuration信息，比如，a 1 a 2 a 3＝000指示了LTE中Uplink-downlink configuration索引为0的配置信息，即表3中Uplink-downlink configuration值为0的配置信息。又例如，比特串a 5a 6a 7a 8指示了LTE的Special subframe configuration信息，比如，a 5a 6a 7a 8＝0001指示LTE中Special subframe configuration索引为1的配置，即表4中Special subframe configuration值为1的配置信息。
在一个示例实施例中，PSBCH中，利用指示tdd-UL-DL-ConfigurationCommon配置的12比特a 0～a 11中的部分或全部指示频分双工FDD帧结构。
例如，PSBCH中指示tdd-UL-DL-ConfigurationCommon配置的12比特a 0～a 11全为0或全为1，或者其中的7比特a 5～a 11全为0或全为1，表示NR或LTE的无线帧结构为FDD类型。
例如，PSBCH中用来指示tdd-UL-DL-ConfigurationCommon配置中单双周期配置的比特a 0的指示值为0，用来指示tdd-UL-DL-ConfigurationCommon配置中DL-UL pattern配置周期值的4比特a 1a 2a 3a 4为1001，1010，1011，1100，1101，1111中的任意一个值，表示NR或LTE的无线帧结构为FDD类型。
例如，PSBCH中用来指示tdd-UL-DL-ConfigurationCommon配置中包含的可用于sidelink资源映射的UL slot数的7比特a 5a 6a 7a 8a 9a 10a 11都是1或都是0，表示表示NR或LTE的无线帧结构为FDD类型。
例如，PSBCH中用来指示tdd-UL-DL-ConfigurationCommon配置中单双周期配置的比特a 0的指示值为0，用来指示tdd-UL-DL-ConfigurationCommon配置中包含的可用于sidelink资源映射的UL slot数的7比特a 5a 6a 7a 8a 9a 10a 11都是0，表示表示NR或LTE的无线帧结构为FDD类型。
例如，PSBCH中指示的tdd-UL-DL-ConfigurationCommon配置的周期内都是UL subframe或UL slot；或者，PSBCH中指示的tdd-UL-DL-ConfigurationCommon配置的周期内没有UL subframe或UL slot。
在一个示例实施例中，利用PSBCH中预留比特指示频分双工FDD帧结构。
例如，利用PSBCH中预留比特中的1比特的值为1或0，表示NR或LTE的无线帧结构为FDD类型。例如，利用PSBCH中预留比特中的两比特的值为00，01，10，11中任意一个值，表示NR或LTE的无线帧结构为FDD类型。
