Description

传输侧行链路数据的方法和终端设备 技术领域
本申请涉及通信领域，尤其涉及传输侧行链路数据的方法和终端设备。
背景技术
车联网系统是基于长期演进(Long Term Evolution，LTE)终端直连(Device to Device，D2D)的一种侧行链路(Sidelink，SL)传输技术，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。
在NR系统的车联网技术(vehicle to everything，V2X)中，可能存在多种传输方式，如：单播传输、组播传输和广播传输。在单播传输中，接收端只有一个特定的终端设备；在组播传输中，建立一个通信组，当该组中的一个终端设备发送数据时，例如，在该组中具有资源协调、管理、分配、控制等功能的组头终端设备发送数据，该组内的其他终端设备是接收终端，其中，单播传输可以看作是一种特殊的组播传输，即该组中只有两个终端设备；在广播传输中，一个终端设备发送数据，其他的终端设备都是接收终端。
由于一个终端设备可以参与到多个组播通信或广播通信中，若该终端设备在一个组播通信中的某一时刻需要接收数据，但是在另一个组播通信或者广播通信中，该终端设备在该时刻又需要发送数据，那么就会产生冲突。

应理解，本文中术语“系统”和“网络”在本文中常被可互换使用。本文中术语“和/或”，仅仅是一种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这三种情况。另外，本文中字符“/”，一般表示前后关联对象是一种“或”的关系。
在3GPP的版本14(Rel-14)中对V2X进行了标准化，定义了两种传输模式：模式3和模式4。其中，图2示出了根据本申请实施例的车联网系统中两种传输模式的示意图。
如图2所示，左侧的模式3表示：车载终端的传输资源是由基站通过下行链路(downlink，DL)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。
如图2所示，右侧的模式4表示：车载终端采用侦听(sensing)和预留(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。
在NR-V2X系统中，与上述类似，也引入了多种传输模式，例如，可以包括模式1和模式2，其中，模式1是网络设备为终端分配传输资源，也就是类似于LTE-V2X中的模式3，终端设备采用网络设备分配的传输资源；而模式2是终端设备选取传输资源，在模式2下又分为几种子模式(Mode)，例如，具体可以包括以下几种。
一、Mode 2a：由终端设备自主选取传输资源，类似于上述的LTE-V2X中的模式4；例如，该终端在一个预配置或网络配置的资源池中自主选取资源，可以通过随机的方式选取资源，或者通过侦听的方式选取资源。
二、Mode 2b：终端辅助其他终端选取资源；例如，第一终端向第二终端发送辅助信息，接收到辅助信息的终端设备可以依据该辅助信息，确定传输资源，其中，该辅助信息可以包括以下信息中的一个或者多个：可用的时频资源信息、可用的传输资源集合信息、信道测量信息和信道质量信息等，如信道状态信息(Channel State Information，CSI)、信道质量指示(Channel Quality Indicator，CQI)、预编码矩阵指示(Precoding Matrix  Indicator，PMI)、秩指示(rank indication，RI)、参考信号接收功率(Reference Signal Receiving Power，RSRP)、接收信号质量(Reference Signal Receiving Quality，RSRQ)、接收信号强度指示(Received Signal Strength Indicator，RSSI)、干扰信息以及路损信息等。
三、Mode 2c：终端设备在为其配置的传输资源中选取资源；例如，网络设备可以为一组终端设备中每个终端配置传输资源，其中，每个终端设备的传输资源可以相同也可以不同，当其中任意一个终端有侧行数据传输时，可以使用网络设备配置的传输资源进行数据传输，例如，当网络设备为一组终端设备中每个终端设备均配置相同资源时，需要进行侧行数据传输的终端设备可以在配置的资源中通过侦听等方式选择可以使用的资源；或者，网络设备也可以为一组终端设备中每个终端设备配置不同的传输资源，需要进行侧行数据传输的终端设备可以在为其配置的资源中选择可用的资源。
四、Mode 2d：第一终端设备为第二终端设备分配传输资源；例如，对于组播链路中的多个终端设备，若第一终端设备为该组链路中的组头，第二终端设备是该组的组成员，第一终端设备可以直接为第二终端设备分配侧行链路传输的时频资源。
另外，在NR V2X中，也可能存在多种传输方式，如：单播传输(Unicast)、组播传输(Groupcast)和广播传输(Broadcast)。在单播传输中，接收端只有一个特定的终端设备；在组播传输中，建立一个通信组，当该组中的一个终端设备发送数据时，例如，在该组中具有资源协调、管理、分配、控制等功能的组头终端设备发送数据，该组内的其他终端都可以是目标接收终端；其中，单播传输可以看做是一种特殊的组播传输，即组播传输时若该组中只有两个终端设备即为单播传输。在广播传输中，一个终端设备发送数据，其他的终端设备都是目标接收终端。
在组播(或者单播)传输中，组头可以为组成员分配传输资源，例如，终端设备可以采用上述如mode 2d的资源分配方式，并且，一个终端设备可以参与到一个或者多个组播通信中。例如，以图3为例，图3是根据本申请实施例的两个组播传输的示意图。如图3所示，UE1、UE2和UE3构成第一通信组，UE1是组头；UE3、UE4和UE5构成第二通信组，UE5是组头。其中，UE3同时在两个通信组中，在第一组中，UE1可以为UE3分配传输资源，在第二组中，UE5可以为UE3分配传输资源，当在某一个时刻，UE1指示UE3在该时刻接收数据，但UE5指示UE3在该时刻发送数据，此时UE3如何处理？
或者，UE3在第一组中进行组播传输，同时UE3还需要进行广播传输，在组播传输中，UE1为UE3分配传输资源，在广播传输中，UE3自主选取传输资源，如采用Mode 2a，在某一个时刻，UE1指示UE3接收数据，但是UE3选取该时间发送数据，UE3如何处理？
因此，本申请实施例提出了一种传输侧行链路数据的方法，可以解决终端设备在某一时刻既发送数据又接收数据的冲突。
图4示出了根据本申请实施例的传输侧行链路数据的方法200的示意性流程图，该方法200可以由任意一个终端设备执行，具体地，该终端设备可以与其他终端设备进行侧行链路通信，例如该终端设备可以为图1、图2或图3所示的任意一个终端设备。如图4所示，该方法200包括：S210，在终端设备根据第一配置信息，确定在目标传输资源上接收第一侧行传输信道，以及根据第二配置信息，确定在该目标传输资源上发送第二侧行传输信道的情况下，该终端设备按照第一规则，在该目标传输资源上接收该第一侧行传输信道或发送该第二侧行传输信道。
应理解，在S210之前，该方法200还包括：终端设备根据第一配置信息，确定在目标传输资源上接收第一侧行传输信道；另外，该方法200还包括：终端设备根据第二配置信息，确定在该目标传输资源上发送第二侧行传输信道。也就是，在同一目标传输资源上，既配置了侧行链路的接收数据，又配置了发送数据，会发生资源冲突。
在本申请实施例中，该第一侧行传输信道和第二侧行传输信道指该终端设备与其他 终端设备之间的侧行链路通信。具体地，终端设备在目标传输资源上接收第一侧行传输信道，包括：该终端设备使用该目标传输资源，通过第一侧行传输信道接收其他终端设备发送的数据；终端设备在目标传输资源上发送第二侧行传输信道，包括：该终端设备通过该第二侧行传输信道向其他终端设备发送数据。
可选的，该第一侧行传输信道或者该第二侧行传输信道可以为以下信道中的任意一个：物理侧行链路控制信道(Physical Sidelink Control Channel，PSCCH)、物理侧行链路共享信道(Physical Sidelink Shared Channel，PSSCH)、物理侧行链路广播信道(Physical Sidelink Broadcast Channel，PSBCH)和物理侧行链路反馈信道(Physical Sidelink Feedback Channel，PSFCH)。
可选的，本申请方法200适用于侧行传输信道，同时也适用于侧行链路信号的传输，例如，该第一侧行传输信道或者该第二侧行传输信道也可以用侧行链路同步信号(Sidelink Synchronization Signal，SLSS)进行替代，其中，该SLSS可以包括侧行链路主同步信号(Sidelink-Primary synchronization signal，S-PSS)和/或侧行链路辅同步信号(Sidelink-Secondary synchronization signal，S-SSS)，本申请实施例并不限于此。
应理解，本申请实施例中的目标传输资源可以为时域资源，或者也可以为时频资源。具体的，若该目标传输资源为时域资源，终端设备根据第一配置信息确定采用该时域资源接收第一侧行传输信道，同时也发送第二侧行传输信道，而该第一侧行传输信道和第二侧行传输信道对应的频域资源可以相同或者也可以不同。
在本申请实施例中，终端设备根据第一配置信息和第二配置信息，确定在同一目标传输资源上需要接收第一侧行传输信道以及发送第二侧行传输信道的情况下，终端设备可以按照第一规则，选择在该目标传输资源上执行接收第一侧行传输信道或者选择执行发送第二侧行传输信道。其中，该第一规则可以为预先配置，例如，可以为协议规定；或者，该第一规则也可以由网络设备为该终端设备配置，本申请实施例并不限于此。
应理解，该第一规则可以包括多种实施例，下面将结合几个具体实施例，举例并详细描述该第一规则。
实施例一
该第一规则为：该终端设备根据该第一侧行传输信道上的待接收数据的第一参数信息和该第二侧行传输信道上的待发送数据的第二参数信息的比较结果，在该目标传输资源上接收该第一侧行传输信道或发送该第二侧行传输信道。
具体地，终端设备可以获取该第一侧行传输信道上的待接收数据的第一参数信息，还可以获取第二侧行传输信道上的待发送数据的第二参数信息。其中，该第一参数信息可以为该终端设备接收其他终端设备发送的，该其他终端设备为要向该终端设备发送该第一侧行传输信道的终端设备。
终端设备根据第一参数信息和第二参数信息的比较结果，选择在该目标传输资源上接收第一侧行传输信道或者发送第二侧行传输信道。其中，该第一参数信息和第二参数信息的比较结果与其包括的具体参数有关。
可选的，作为一个实施例，该第一参数信息为该待接收数据的优先级信息，该第二参数信息为该待发送数据的优先级信息，则终端设备可以根据优先级的比较结果，选择在该目标传输资源上接收第一侧行传输信道或者发送第二侧行传输信道。具体地，若该待接收数据的优先级高于该待发送数据的优先级，该终端设备在该目标传输资源上接收该第一侧行传输信道；或者，若该待接收数据的优先级低于该待发送数据的优先级，该终端设备在该目标传输资源上发送该第二侧行传输信道。
可选的，该待接收数据和/或待发送数据的优先级信息可以在侧行链路控制信息(Sidelink Control Information，SCI)中携带，例如，通过邻近业务每业务包优先级(ProSe Per-Packet Priority，PPPP)数值表示优先级高低，PPPP数值越低，优先级等级越高，但本申请实施例并不限于此。
例如，第一侧行传输信道上的待接收数据的PPPP值为1，第二侧行传输信道上的待发送数据的PPPP值为3，因为PPPP值越低表示优先级越高，因此待接收数据的优先级高于待发送数据的优先级，因此该终端设备在目标资源上接收该第一侧行传输信道。
可选的，作为一个实施例，该第一参数信息为该待接收数据的时延信息，该第二参数信息为该待发送数据的时延信息；则终端设备可以根据待接收数据和待发送数据对时延的要求，比较时延大小，进而选择在该目标传输资源上接收第一侧行传输信道或者发送第二侧行传输信道。具体地，若该待接收数据的时延小于该待发送数据的时延，该终端设备在该目标传输资源上接收该第一侧行传输信道；或者，若该待接收数据的时延大于该待发送数据的时延，该终端设备在该目标传输资源上发送该第二侧行传输信道。
例如，第一侧行传输信道上的待接收数据的时延需求为10ms，第二侧行传输信道上的待发送数据的时延需求为100ms，待接收数据的时延低于待发送数据的时延，时延越低表示业务越紧迫，因此该终端设备在目标资源上接收该第一侧行传输信道。
可选的，作为一个实施例，该第一参数信息为该待接收数据的可靠性信息，该第二参数信息为该待发送数据的可靠性信息；则终端设备可以根据待接收数据和待发送数据对可靠性的要求，比较可靠性大小，进而选择在该目标传输资源上接收第一侧行传输信道或者发送第二侧行传输信道。具体地，若该待接收数据的可靠性大于该待发送数据的可靠性，该终端设备在该目标传输资源上接收该第一侧行传输信道；或者，若该待接收数据的可靠性小于该待发送数据的可靠性，该终端设备在该目标传输资源上发送该第二侧行传输信道。
例如，第一侧行传输信道上的待接收数据的可靠性需求为90％，第二侧行传输信道上的待发送数据的可靠性需求为99％，待接收数据的可靠性需求低于待发送数据的可靠性需求，因此该终端设备在目标资源上发送该第二侧行传输信道。
可选的，该第一参数信息和第二参数信息还可以为其他参数信息，例如，该第一参数信息为待接收数据的服务质量(Quality of Service，QoS)信息，第二参数为待发送数据的QoS信息，终端设备根据待接收数据和待发送数据的QoS等级选择选择在该目标传输资源上接收或者发送数据。为了简洁，在此不再一一列举。
可选的，上述各个实施例中，以该第一参数信息和第二参数信息各包括一个信息为例进行说明，但是该第一参数信息和第二参数信息中也可以包括多个信息，通过多个信息综合判断。例如，该第一参数信息和第二参数信息均包括优先级信息和时延信息，可以先比较优先级，若第一参数信息中的优先级与第二参数信息中的优先级不相等，则可以按照上述关于优先级的比较结果，选择在目标传输资源上接收第一侧行传输信道或者发送第二侧行传输信道；若第一参数信息中的优先级与第二参数信息中的优先级相等，可以再比较第一参数信息中的时延信息和第二参数信息中的时延信息，根据时延信息比较结果，选择在目标传输资源上接收第一侧行传输信道或者发送第二侧行传输信道。因此，在该第一参数信息和第二参数信息包括多个参数时，可以互相结合使用，本申请实施例并不限于此。
实施例二
该第一规则为：若该第一侧行传输信道的传输类型的优先级高于该第二侧行传输信道的传输类型的优先级，该终端设备在该目标传输资源上接收该第一侧行传输信道；或者，若该第一侧行传输信道的传输类型的优先级低于该第二侧行传输信道的传输类型的优先级，该终端设备在该目标传输资源上发送该第二侧行传输信道。
在本申请实施例中，第一侧行传输信道或者第二侧行传输信道的传输类型可以为单播传输、组播传输或者广播传输，其中，单播传输也可以看作一种特殊的组播传输。为了便于说明，以下提到的单播传输指两个终端设备之间的侧行链路通信，而组播传输指三个或者多于三个的终端设备之间的侧行链路通信。
在本申请实施例中，侧行传输信道的传输类型的优先级可以根据实际应用进行设置， 或者根据协议规定，或者根据网络进行配置。例如，通常可以设置为单播传输和组播传输的优先级均高于广播传输；而单播传输的优先级与组播传输的优先级可以相等，也可以不相等，或者根据其他条件判断单播传输的优先级与组播传输的优先级的高低；或者，也可以设置为单播传输的优先级高于或低于组播传输的优先级，但本申请实施例并不限于此。
实施例三
该第一规则为：该终端设备根据该第一配置信息和该第二配置信息中该目标传输资源的分配方式，在该目标传输资源上接收该第一侧行传输信道或发送该第二侧行传输信道。
应理解，终端设备的目标传输资源的分配方式可以有多种，例如上述在NR系统中的模式1和模式2，其中，模式2还可以包括Mode 2a-2d等多种子模式。终端设备根据第一配置信息确定的目标传输资源的方式与根据第二配置信息确定的目标传输资源的方式可能不同，因此，可以根据目标传输资源的分配方式，选择在目标传输资源上接收该第一侧行传输信道或发送该第二侧行传输信道。
可选的，按照分配该目标传输资源的主体的不同，可以将目标传输资源的分配方式分为网络设备分配、其他终端设备分配和该终端设备自身分配。因此，该第一配置信息或者第二配置信息中该目标传输资源的分配方式可以为以下方式中的任意一种：网络设备分配、其他终端设备分配和该终端设备分配。
具体地，该第一配置信息或者第二配置信息中该目标传输资源的分配方式为网络设备分配表示：网络设备向该终端设备发送第一配置信息或者第二配置信息，其中，该第一配置信息或者第二配置信息可以为网络设备发送的调度信息或者资源池配置信息。即由网络设备通过该第一配置信息分配该目标传输资源给该终端设备以用于接收第一侧行传输信道，或者，由网络设备通过该第二配置信息分配该目标传输资源给该终端设备以用于发送第二侧行传输信道。
类似的，该第一配置信息或者第二配置信息中该目标传输资源的分配方式为其他终端设备分配表示：其他终端设备向该终端设备发送第一配置信息或者第二配置信息，其中，其他终端设备与终端设备为不同的终端设备，该其他终端设备可以指除了该终端设备之外的任意一个终端设备。即其他终端设备通过第一配置信息分配该目标传输资源给该终端设备以用于接收第一侧行传输信道，或者，其他终端设备通过该第二配置信息分配该目标传输资源给该终端设备以用于发送第二侧行传输信道。
该第一配置信息或者第二配置信息中该目标传输资源的分配方式为该终端设备自身进行分配，表示：该第一配置信息或者第二配置信息为该终端设备自身确定的，即终端设备确定第一配置信息，确定采用目标传输资源接收第一侧行传输信道；或者，该终端设备确定第二配置信息，确定采用目标传输资源发送第二侧行传输信道，其中，该第一配置信息或者该第二配置信息可以来自于该终端设备的高层，如应用层，或者无线链路控制层，或者媒体接入控制层。。
应理解，不同的资源分配方式可以对应于不同的优先级，例如，通常可以设置为网络设备分配资源的资源分配方式的优先级最高，例如，上述模式1的优先级大于模式2的优先级，假设终端设备采用模式1，根据第一配置信息确定在目标传输资源上接收第一侧行传输信道；采用模式2(上述模式2中任意一种，例如，模式2中的Mode 2a)，根据第二配置信息确定在目标传输资源上发送第二侧行传输信道，由于模式1的优先级大于模式2的优先级，则终端设备选择在目标传输资源上接收第一侧行传输信道。另外，其他终端设备分配的以及终端设备自身分配的优先级可以相同，或者也可以不同，例如，还可以将其他终端设备分配资源的资源分配方式的优先级设置为高于终端设备自身分配资源的资源分配方式的优先级，例如，上述Mode 2d或者Mode 2b的优先级大于Mode 2a的优先级，但本申请实施例并不限于此。
例如，若该第一配置信息中的该目标传输资源为该网络设备分配的，该第二配置信息中的该目标传输资源为该其他终端设备分配的或者该终端设备自身分配的，则该终端设备可以优先接收第一侧行传输信道，即在该目标传输资源上接收该第一侧行传输信道；或者，若该第一配置信息中的该目标传输资源为该其他终端设备分配的或者该终端设备自身分配的，该第二配置信息中的该目标传输资源为该网络设备分配的，则该终端设备可以优先发送第二侧行传输信道，即在该目标传输资源上发送该第二侧行传输信道。
再例如，若该第一配置信息中的该目标传输资源为该其他终端设备分配的，该第二配置信息中的该目标传输资源为该终端设备自身分配的，该终端设备可以优先接收第一侧行传输信道，即在该目标传输资源上接收该第一侧行传输信道；或者，若该第一配置信息中的该目标传输资源为该终端设备自身分配的，该第二配置信息中的该目标传输资源为该其他终端设备分配的，该终端设备可以优先发送第二侧行传输信道，即在该目标传输资源上发送该第二侧行传输信道。
可选地，可以通过预配置的方式，协议规定的方式或者网络配置的方式确定各种资源分配方式之间的优先级。
实施例四
该第一规则为：该终端设备根据该第一侧行传输信道和该第二侧行传输信道的类型，在该目标传输资源上接收该第一侧行传输信道或发送该第二侧行传输信道。
在本申请实施例中，第一侧行传输信道或者第二侧行传输信道的类型可以为以下任意一种：PSCCH、PSSCH、PSBCH和PSFCH，该四种信道的优先级顺序，可以根据实际应用进行设置，或者根据预配置信息进行设置，或者根据网络配置信息进行设置。例如，可以将PSCCH和PSSCH的优先级设置为低于PSBCH和PSFCH。
具体地，若该第一侧行传输信道为PSBCH或PSFCH，该第二侧行传输信道为PSCCH或PSSCH，该终端设备优先接收第一侧行传输信道，即在该目标传输资源上接收该第一侧行传输信道；或者，若该第一侧行传输信道为PSCCH或PSSCH，该第二侧行传输信道为PSBCH或PSFCH，该终端设备优先发送第二侧行传输信道，即在该目标传输资源上发送该第二侧行传输信道。
应理解，上述第一规则的四种实施例可以分开独立使用，也可以将其中多个实施例结合使用，或者将其中一种或者多种实施例结合其他方式共同使用。例如，当采用如实施例一中第一参数信息和第二参数信息的比较结果进行选择时，若两个参数信息的比较结果相同，则无法确定在目标传输资源上接收第一侧行传输信道还是发送第二侧行传输信道，此时，可以采用其他方式再次进行判断，例如再采用实施例二的方式再次进行判断，直到可以判断出，在该目标传输资源上接收第一侧行传输信道还是第二侧行传输信道为止。
在本申请实施例中，假设终端设备需要在目标传输资源接收第一终端设备发送的第一侧行传输信道，以及向第二终端设备发送第二侧行传输信道时，由于会发生冲突，该终端设备根据第一规则，最终选择在目标传输资源上接收第一侧行传输信道或者发送第二侧行传输信道。对应的，对于该终端设备最终的判断结果，该第一终端设备和第二终端设备可以获取该判断结果，确定由该第一终端设备在该目标传输资源上发送第一侧行传输信道，或者第二终端设备在该目标传输资源上接收第二侧行传输信道。其中，该第一终端设备和第二终端设备可以为任意终端设备，并且二者可以为相同或者不同的终端设备，本申请实施例并不限于此。
因此，本申请实施例的传输侧行链路数据的方法，对于任意传输资源，在终端设备既被配置发送数据，又被配置接收数据时，可以根据待发送数据和待接收数据的优先级，或者侧行传输的传输模式，或者该资源的分配方式，或者信道类型等，确定使用该传输资源发送或者接收数据，以解决终端设备的侧行传输冲突的问题。
应理解，在本申请的各种实施例中，上述各过程的序号的大小并不意味着执行顺序 的先后，各过程的执行顺序应以其功能和内在逻辑确定，而不应对本申请实施例的实施过程构成任何限定。
另外，本文中术语“和/或”，仅仅是一种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这三种情况。另外，本文中字符“/”，一般表示前后关联对象是一种“或”的关系。
上文中结合图1至图4，详细描述了根据本申请实施例的传输侧行链路数据的方法，下面将结合图5至图8，描述根据本申请实施例的终端设备。
如图5所示，根据本申请实施例的终端设备300包括：处理单元310和收发单元320，具体地，该收发单元320用于：在该处理单元310根据第一配置信息，确定在目标传输资源上接收第一侧行传输信道，以及根据第二配置信息，确定在该目标传输资源上发送第二侧行传输信道的情况下，按照第一规则，在该目标传输资源上接收该第一侧行传输信道或发送该第二侧行传输信道。
