Description

用户设备及用户设备之间发送和接收定位信号的方法 技术领域
本申请涉及无线通信领域，特别涉及一种用户设备之间发送和接收定位信号的技术。
背景技术
车联网系统是基于LTE-D2D的一种侧行链路传输技术(SL：Sidelink，侧行链路)，与传统的LTE系统中通信数据通过基站接收或者发送的方式不同，车联网系统采用终端到终端直接通信的方式，因此具有更高的频谱效率以及更低的传输时延。
但是,车联网系统中仍然存在的问题是定位精度的问题，即单独靠卫星定位(例如GPS，北斗等)的定位精度无法区别车道(需要亚米级定位)，这就需要通过车车之间再次相互定位，从而对GPS定位的精度进行修正。而这带来的首要问题就是如何在车车之间进行相互定位，即如何发送车车定位的信号。
发明内容
本申请的目的在于提供一种用户设备及用户设备之间发送和接收定位信号的方法，通过用户设备之间的相互定位，从而达到更高的定位精度。
为了解决上述问题，本申请公开了一种用户设备之间发送定位信号的方法，包括：
第一用户设备在通信接口上发送定位参考信号，并且在物理侧行控制信道PSCCH和/或物理侧行共享信道PSSCH进行信息发射，其中，该PSCCH和/或PSSCH的信息发射指示该定位参考信号的相关属性。
本申请还公开了一种用户设备之间接收定位信号的方法，包括：
第二用户设备在通信接口上接收定位参考信号，并且在与第一用户设备对应的物理侧行控制信道PSCCH和/或物理侧行共享信道PSSCH进行信息接收；
该第二用户设备根据该PSCCH和/或PSSCH的信息接收确定该定位参考信号的相关属性。
本申请还公开了一种用户设备，包括：
第一发送模块，用于在通信接口上发送定位参考信号；
第二发送模块，用于在物理侧行控制信道PSCCH和/或物理侧行共享信道PSSCH进行信息发射，其中，该PSCCH和/或PSSCH的信息发射指示该定位参考信号的相关属性。
本申请还公开了一种用户设备，包括：
第一接收模块，用于在通信接口上接收定位参考信号；
第二接收模块，用于在物理侧行控制信道PSCCH和/或物理侧行共享信道PSSCH进行信息接收；
确定模块，用于根据该PSCCH和/或PSSCH的信息接收确定该定位参考信号的相关属性。
本申请还公开了一种计算机存储介质，其上存储有计算机可执行指令，该计算机可执行指令被处理器执行时实现权利要求1-12中任一项所述的方法步骤，或者权利要求13-24中任一项所述的方法步骤。
本申请实施方式与现有技术相比，通过用户设备和用户设备之间直接通信的方式来实现用户设备之间的相互定位，具有更高的频谱效率以及更低的传输时延，能够达到更高的定位精度。
本申请的说明书中记载了大量的技术特征，分布在各个技术方案中，如果要罗列出本申请所有可能的技术特征的组合(即技术方案)的话，会使得说明书过于冗长。为了避免这个问题，本申请上述发明内容中公开的各个技术特征、在下文各个实施方式和例子中公开的各技术特征、以及附图中公开的各个技术特征，都可以自由地互相组合，从而构成各种新的技术方案(这些技术方案均因视为在本说明书中已经记载)，除非这种技术特征的组合在技术上是不可行的。例如，在一个例子中公开了特征A+B+C，在另一个例子中公开了特征A+B+D+E，而特征C和D是起到相同作用的等同技术手段，技术上只要择一使用即可，不可能同时采用，特征E技术上可以与特征C相组合，则，A+B+C+D的方案因技术不可行而应当不被视为已经记载，而A+B+C+E的方案应当视为已经被记载。

具体实施方式
在以下的叙述中，为了使读者更好地理解本申请而提出了许多技术细节。但是，本领域的普通技术人员可以理解，即使没有这些技术细节和基于以下各实施方式的种种变化和修改，也可以实现本申请所要求保护的技术方案。

下面简要介绍一下本申请的应用场景：
在3GPP Rel-14中对车联网技术(V2X)进行了标准化，定义了两种传输模式：模式3和模式4，具体地说：
模式3：如图1所示，车载终端的传输资源是由基站分配的，车载终端根据基站分配的资源在侧行链路上进行数据的发送；基站可以为终端分配单次传输的资源，也可以为终端分配半静态传输的资源。
模式4：如图2所示，车载终端采用侦听(sensing)+预留(reservation)的传输方式。车载终端在资源池中通过侦听的方式获取可用的传输资源集合，终端从该集合中随机选取一个资源进行数据的传输。由于车联网系统中的业务具有周期性特征，因此终端通常采用半静态传输的方式，即终端选取一个传输资源后，就会在多个传输周期中持续的使用该资源，从而降低资源重选以及资源冲突的概率。终端会在本次传输的控制信息中携带预留下次传输资源的信息，从而使得其他终端可以通过检测该用户的控制信息判断这块资源是否被该用户预留和使用，达到降低资源冲突的目的。
为使本申请的目的、技术方案和优点更加清楚，下面将结合附图对本发明的实施方式作进一步地详细描述。
首先，需要说明的是，
在本申请的各实施方式中，所提到的用户设备可以是多种多样的，例如智能手机、平板电脑、台式电脑、笔记本电脑、定制的无线终端、物联网节点、无线通信模块等等，只要相互之间能够根据约定的通信协议进行无线通信即可。
本申请的技术方案可以(但不限于)应用于车联网系统中。
本申请第一实施方式涉及一种用户设备之间发送定位信号的方法。图3是该用户设备之间发送定位信号的方法的流程示意图。
具体地说，如图3所示，该用户设备之间发送定位信号的方法包括：
在步骤301中，第一用户设备在通信接口上发送定位参考信号。
在步骤302中，在物理侧行控制信道PSCCH和/或物理侧行共享信道PSSCH进行信息发射，其中，PSCCH和/或PSSCH的信息发射指示定位参考信号的相关属性。
需要说明的是，步骤301和步骤302没有必然的先后关系，可以先发送定位参考信号，再在PSCCH和/或PSSCH进行信息发射；也可以先在PSCCH和/或PSSCH进行信息发射，再发送定位参考信号；也可以同时发送定位参考信号，和在PSCCH和/或PSSCH进行信息发射。
此后结束本流程。
在步骤301中，通信接口是指用户设备和用户设备之间的通信接口，在本实施方式中，优选地，为PC5接口。
在步骤302中，第一用户设备具有对应的PSCCH和/或PSSCH，在与第一用户设备对应的PSCCH和/或PSSCH进行信息发射，该信息发射包含了PSCCH和/或PSSCH与定位参考信号PRS的对应关系。换句话说，在步骤302中，通过确定PSCCH和/或PSSCH与PRS的对应关系，从而确定发送UE(第一用户设备)与PRS的对应关系。
定位参考信号的相关属性包括至少以下之一：定位参考信号的时间位置、频率位置、以及信号序列。
步骤302可以有多种实现方式，下面举例说明：
步骤302的第一种实现方式可以是，通过PSCCH和/或PSSCH进行信息发射的时间位置和/或频率位置指示定位参考信号的相关属性。换句话说，定位参考信号的相关属性可以通过PSCCH和/或PSSCH进行信息发射的时间位置和/或频率位置隐式获得。该第一种实现方式，也可以有多种优选的实施例，具体如下所述：
实施例1：定位参考信号的时间位置与PSCCH和/或PSSCH进行信息发射的时间位置是相同的；或者，定位参考信号的时间位置与PSCCH和/或PSSCH进行信息发射的时间位置是一一对应的。
实施例2：PSCCH单独调度定位参考信号；或者，PSCCH调度PSSCH的同时，对应定位参考信号。
实施例3：定位参考信号的频率位置与PSCCH和/或PSSCH进行信息发射的频率位置是相同的；或者，定位参考信号的频率位置与PSCCH和/或PSSCH进行信息发射的频率位置是一一对应的。
实施例4：定位参考信号的频率位置与PSCCH和/或PSSCH进行信息发射的频率位置是不同的。例如，定位参考信号占用比PSCCH和/或PSSCH更大的带宽。或者，定位参考信号占用PSCCH和/或PSSCH的全带宽，在这种情况下，可以只允许占用PSSCH和/或PSSCH的特定时间位置和/或频率位置的第一用户设备发送定位参考信号。
步骤302的第二种实现方式可以是，通过PSCCH和/或PSSCH所发射的 信息的内容指示定位参考信号的相关属性。换句话说，定位参考信号的相关属性可以通过PSCCH和/或PSSCH所发射的信息的内容显式获得。该第二种实现方式，也可以有多种优选的实施例，具体如下所述：
实施例1：定位参考信号的时间位置通过PSCCH和/或PSSCH所发射的信息的内容指示。
实施例2：定位参考信号的频率位置通过PSCCH和/或PSSCH所发射的信息的内容指示。
实施例3：定位参考信号的信号序列是在PSCCH和/或PSSCH所发射的信息中包含的特定比特，或者能够通过PSCCH和/或PSSCH所发射的信息中包含的其他信息推得。
定位参考信号的信号序列通过PSCCH和/或PSSCH所发射的信息中包含的其他信息推得的情况，例如，可以通过PSCCH和/或PSSCH所发射的信息中包含的用户标识信息推得。举个例子来说，假设发射数据块中共有8个信号序列，该用户标识信息为1个字节(8个比特)的长度，将该8个比特的用户标识信息的值进行取模8运算得到的结果为7，则PRS为发射数据块中的第7个信号序列。或者，也可以通过PSCCH和/或PSSCH所发射的信息中包含的DMRS的特征推得，比如通过DMRS的循环移位(cyclic shift)推得。
或者，除了信号序列之外，定位参考信号的其余相关属性也可以是在PSCCH和/或PSSCH所发射的信息中包含的特定比特。
或者，定位参考信号的其余相关属性也能够通过PSCCH和/或PSSCH所发射的信息中包含的其他信息推得。例如，可以通过PSCCH和/或PSSCH所发射的信息中包含的用户标识信息推得。又例如，可以通过PSCCH和/或PSSCH所发射的信息中包含的DMRS的特征推得，比如通过DMRS的循环移位(cyclic shift)推得。
实施例4：PSCCH单独调度定位参考信号；或者，PSCCH调度PSSCH的同时，对应定位参考信号。
实施例5：定位参考信号的频率位置与PSCCH和/或PSSCH进行信息发射的频率位置是相同的；或者，定位参考信号的频率位置与PSCCH和/或PSSCH进行信息发射的频率位置是一一对应的。
实施例6：定位参考信号的频率位置与PSCCH和/或PSSCH进行信息发射的频率位置是不同的。例如，定位参考信号占用比PSCCH和/或PSSCH更大的带宽。或者，定位参考信号占用PSCCH和/或PSSCH的全带宽，在这种情况下，可以只允许占用PSSCH和/或PSSCH的特定时间位置和/或频率位置的第一用户设备发送定位参考信号。
此外，需要说明的是，上述列举出的步骤302的两种实现方式可以组合使用，例如，PRS的时频位置可以通过PSCCH和/或PSSCH进行信息发射的时频位置隐式获得，PRS的信号序列可以通过PSCCH和/或PSSCH所发射的信息的内容显式获得；或者反过来，PRS的信号序列通过PSCCH和/或PSSCH进行信息发射的时频位置隐式获得，PRS的时频位置通过PSCCH和/或PSSCH所发射的信息的内容显式获得。
这样，接收用户设备(第二用户设备)通过PSCCH和/或PSSCH就可以获知PRS的时频位置、信号序列，以及发送UE(发送用户设备，即第一用户设备)与PRS的对应关系，从而实现在用户设备之间发送定位信号，在用户设备之间进行相互定位。
本申请第二实施方式涉及一种用户设备之间接收定位信号的方法。
第一实施方式是用户设备之间发送定位信号的方法，第二实施方式是用户设备之间接收定位信号的方法，两者是相对应的过程，技术构思是一致的，相关的细节可以互用。图4是该用户设备之间接收定位信号的方法的流程示意图。
具体地说，如图4所示，该用户设备之间接收定位信号的方法包括：
在步骤401中，第二用户设备在通信接口上接收定位参考信号。
在步骤402中，在与第一用户设备对应的物理侧行控制信道PSCCH和/或物理侧行共享信道PSSCH进行信息接收。
需要说明的是，步骤401和步骤402没有必然的先后关系，可以先接收定位参考信号，再在PSCCH和/或PSSCH进行信息接收；也可以先在PSCCH和/或PSSCH进行信息接收，再接收定位参考信号；也可以同时接收定位参考信号，和在PSCCH和/或PSSCH进行信息接收。
在步骤403中，第二用户设备根据PSCCH和/或PSSCH的信息接收确定定位参考信号的相关属性。
此后结束本流程。
在步骤401中，通信接口是指用户设备和用户设备之间的通信接口，在本实施方式中，优选地，为PC5接口。
在步骤402中，信息接收包含了PSCCH和/或PSSCH与定位参考信号PRS的对应关系。在步骤403中，通过确定PSCCH和/或PSSCH与PRS的对应关系，从而确定发送UE(第一用户设备)与PRS的对应关系。
需要说明的是，本申请第一实施方式中PSCCH和/或PSSCH进行信息发射的时间位置、频率位置、所发射的信息的内容与本实施方式中PSCCH和/或PSSCH进行信息接收的时间位置、频率位置、所接收的信息的内容是相同的。
定位参考信号的相关属性包括至少以下之一：定位参考信号的时间位置、频率位置、以及信号序列。
步骤403可以有多种实现方式，下面举例说明：
步骤403的第一种实现方式可以是，通过PSCCH和/或PSSCH进行信息接收的时间位置和/或频率位置确定定位参考信号的相关属性。换句话说，定位参考信号的相关属性可以通过PSCCH和/或PSSCH进行信息接收的时间位置和/或频率位置隐式获得。该第一种实现方式，也可以有多种优选的实施例，具体如下所述：

步骤403的第二种实现方式可以是，通过PSCCH和/或PSSCH所接收的信息的内容确定定位参考信号的相关属性。换句话说，定位参考信号的相关属性能够通过PSCCH和/或PSSCH所接收的信息的内容显式获得。该第二种实现方式，也可以有多种优选的实施例，具体如下所述：
实施例1：定位参考信号的时间位置通过PSCCH和/或PSSCH所接收的信息的内容指示。
实施例2：定位参考信号的频率位置通过PSCCH和/或PSSCH所接收的信息的内容指示。
实施例3：定位参考信号的信号序列是在PSCCH和/或PSSCH所接收的信息中包含的特定比特，或者能够通过PSCCH和/或PSSCH所接收的信息中包含的其他信息推得。
定位参考信号的信号序列通过PSCCH和/或PSSCH所接收的信息中包含的其他信息推得的情况，例如，可以通过PSCCH和/或PSSCH所接收的信息中包含的用户标识信息推得。举个例子来说，假设接收数据块中共有8个信号序列，该用户标识信息为1个字节(8个比特)的长度，将该8个比特的用户标识信息的值进行取模8运算得到的结果为7，则PRS为接收数据块中的第7个信号序列。或者，也可以通过PSCCH和/或PSSCH所接收的信息中包含的DMRS的特征推得，比如通过DMRS的循环移位(cyclic shift)推得。
或者，除了信号序列之外，定位参考信号的其余相关属性也可以是在PSCCH和/或PSSCH所接收的信息中包含的特定比特。
或者，定位参考信号的其余相关属性也能够通过PSCCH和/或PSSCH所接收的信息中包含的其他信息推得。例如，可以通过PSCCH和/或PSSCH所接收的信息中包含的用户标识信息推得。又例如，可以通过PSCCH和/或PSSCH所接收的信息中包含的DMRS的特征推得，比如通过DMRS的循环移位(cyclic shift)推得。

实施例6：定位参考信号的频率位置与PSCCH和/或PSSCH进行信息接收的频率位置是不同的。例如，定位参考信号占用比PSCCH和/或PSSCH更大的带宽。或者，定位参考信号占用PSCCH和/或PSSCH的全带宽，在这种情况下，可以只允许占用所述PSSCH和/或PSSCH的特定时间位置和/或频率位置的第一用户设备发送定位参考信号。
此外，需要说明的是，上述列举出的步骤403的两种实现方式可以组合使用，例如，PRS的时频位置可以通过PSCCH和/或PSSCH进行信息接收的时频位置隐式获得，PRS的信号序列可以通过PSCCH和/或PSSCH所接收的信息的内容显式获得；或者反过来，PRS的信号序列通过PSCCH和/或PSSCH进行信息接收的时频位置隐式获得，PRS的时频位置通过PSCCH和/或PSSCH所接收的信息的内容显式获得。
这样，接收用户设备(第二用户设备)通过PSCCH和/或PSSCH就可以获知PRS的时频位置、信号序列，以及发送UE(发送用户设备，即第一用户设备)与PRS的对应关系，从而实现在用户设备之间发送和接收定位信号，在用户设备之间进行相互定位。
