具体实施方式
这里将详细地对示例性实施例进行说明，其示例表示在附图中。下面的描述涉及附图时，除非另有表示，不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本公开相一致的所有实施方式。相反，它们仅是与如所附权利要求书中所详述的、本公开的一些方面相一致的装置和方法的例子。
本公开实施例提供的基于辅助信息进行资源选择的方法可应用于图1所示的直连通信系统。参阅图1所示，直连通信设备之间进行直连通信的场景中，网络设备为直连通信设备1配置各种用于数据传输的传输参数。直连通信设备1，直连通信设备2和直连通信设备3进行直连通信。直连通信设备2和直连通信设备3之间可以存在障碍物。网络设备与直连通信设备之间进行通信的链路为上下行链路，直连通信设备与直连通信设备之间的链路是直连链路(sidelink)。
本公开中，直连通信设备之间直接通信的通信场景可以是车用无线通信技术(Vehicle to Everything，V2X)业务场景。其中，V代表车载设备，X代表任何与车载设备交互的对象。当前X主要包含车载设备、手持设备、交通路侧基础设施和网络。V2X交互的信息模式包括：车载设备与车载设备之间(Vehicle to Vehicle，V2V)、车载设备与路边设备之间(Vehicle to Infrastructure，V2I)、车载设备与手持设备之间(Vehicle to Pedestrian，V2P)、车载设备与网络之间(Vehicle to Network，V2N)的交互。
随着新一代5G移动通信技术的发展，在3GPP Rel-16中利用5G NR技术实现了对新的V2x通信服务和场景的支持，如车队管理(Vehicles Platooning)，感知扩展(Extended Sensors)，先进驾驶(Advanced Driving)，和远程驾驶(remote driving)等。总体来说，5G V2x sidelink能够提供更高的通信速率，更短的通信延时，更可靠的通信质量。
直连通信设备之间进行直接通信的通信场景也可以是终端到终端(Device to Device，D2D)的通信场景。本公开实施例中进行直接通信的直连通信设备可以包括各种具有无线通信功能的手持设备、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处理设备，以及各种形式的用户设备(User Equipment，UE)，移动台(Mobile station，MS)，终端(terminal)，终端设备(Terminal Equipment)等等。为方便描述，本公开实施例以下以直连通信设备为用户设备为例进行说明。
其中，NR Sidelink的增强可以提高传输可靠性和减小时延。在NR Sidelink的增强中，在增强Mode2资源分配的方面，3GPP工作组达成结论，需要研究一种用户设备间辅助选择资源的方式。在这种方式中，规定了两个用户设备，例如，用户设备A是用户设备B的辅助用户设备，用户设备B是指需要为自身发送的数据进行资源选择的用户设备。其中， 用户设备A提供辅助信息，且通过mode 2的方式发送给用户设备B，用户设备B在进行资源选择时，会考虑用户设备A发送的辅助信息，即可以理解为是用户设备B使用辅助信息协助机制进行资源选择。其中，用户设备B可以将数据发送给用户设备A和/或其他用户设备。
然而，相关技术中针对基于辅助信息进行资源选择的通信方法中，并未讨论如何确定提供辅助信息的用户设备，即在终端间基于辅助信息进行资源选择的方案中，并没有确定提供辅助信息的用户设备A的方案。故，需要设计确定提供辅助信息的用户设备的方法。
本公开实施例提供一种基于辅助信息进行资源选择的方法，在该方法中，进行资源选择的用户设备发送用于确定提供辅助信息用户设备的信息，以实现提供辅助信息用户设备的确定。
其中，基于辅助信息进行资源选择的方法也可以理解为是用户设备间(inter-UE)辅助资源选择中确定辅助用户设备的方法。
本公开实施例中为描述方便，将接收辅助信息并基于辅助信息为自身发送的数据选择资源的用户设备称为第一用户设备，并将提供辅助信息的用户设备称为第二用户设备。即第二用户设备为第一用户设备提供辅助信息，第一用户设备与第二用户设备之间基于辅助信息进行通信，也可以理解为是第一用户设备与第二用户设备之间基于辅助信息进行资源选择。
图2是根据一示例性实施例示出的一种基于辅助信息进行资源选择的方法的流程图，该基于辅助信息进行资源选择的方法可以单独被执行，也可以结合本公开的其他实施例一起被执行。如图2所示，基于辅助信息进行资源选择的方法由第一用户设备执行，包括以下步骤。
在步骤S11中，发送控制信息，控制信息中包括用于确定第二用户设备的字段信息。
本公开实施例中，第二用户设备包括为第一用户设备提供辅助信息的用户设备。即，通过控制信息中携带的字段信息可以确定提供辅助信息的第二用户设备，第二用户设备为第一用户设备提供辅助信息，进而使得第一用户设备和第二用户设备之间可以进行基于辅助信息进行资源选择的通信过程。
本公开实施例以下将结合实际应用对确定第二用户设备的过程进行说明。
本公开实施例中第一用户设备可以指定地理位置区域内的用户设备为第二用户设备。
一种实施方式中，第一用户设备可以通过地理位置区域标识(zone ID)指定地理位置区域内的用户设备为第二用户设备。
一示例中，本公开实施例可以设计新的直连链路控制信息(Sidelink Control  Information，SCI)信息，例如第二阶段直连链路控制信息(second stage Sidelink Control Information，second stage SCI)，在新设计的SCI中携带zone ID字段。通过zone ID指示地理位置区域。在zone ID指示的地理位置区域中确定提供辅助信息的第二用户设备。
进一步的，为使第二用户设备能够确定发送辅助信息的对象(第一用户设备)，可以在新设计的SCI中携带第一用户设备的设备标识(assisted ID)
更进一步的，在zone ID指示的地理位置区域内可能存在多个用户设备，为实现在多个用户设备中确定出第二用户设备，一方面，本公开实施例设计概率因子，并在新设计的SCI中携带概率因子。zone ID指示的地理位置区域内的用户设备随机生成概率因子，将随机生成的概率因子与SCI中携带的概率因子满足预设大小关系的用户设备，确定为第二用户设备。其中，随机生成的概率因子与SCI中携带的概率因子满足的预设大小关系，可以是随机生成的概率因子大于SCI中携带的概率因子，或者也可以是随机生成的概率因子等于SCI中携带的概率因子，或者也可以是随机生成的概率因子小于SCI中携带的概率因子。
图3是根据一示例性实施例示出的一种基于辅助信息进行资源选择的方法的流程图，该基于辅助信息进行资源选择的方法可以单独被执行，也可以结合本公开的其他实施例一起被执行。如图3所示，基于辅助信息进行资源选择的方法由第一用户设备执行，包括以下步骤。
在步骤S21中，发送SCI，SCI中包括zone ID，概率因子以及第一用户设备的assisted ID中的至少一种。
其中，包括zone ID、概率因子以及assisted ID等字段信息的SCI可以是second stage SCI。
其中，包括zone ID、概率因子以及assisted ID等字段信息的SCI，以广播形式发送，使得多个用户设备可以接收到用于确定第二用户设备的SCI。
一种实施方式中，本公开实施例预先配置概率因子集合。例如，通过无线资源控制(Radio Resource Control，RRC)预先配置概率因子集合。其中，网络设备可以基于用户设备标识，对每个用户设备预先配置概率因子集合。网络设备也可以基于小区标识，为每个小区预先配置概率因子集合。即，概率因子集合基于用户设备标识和/或小区标识确定，每一用户设备标识和/或小区标识具有对应的概率因子集合。
本公开实施例可以在预先配置的概率因子集合中确定一个或多个概率因子作为SCI中包括的概率因子。即，SCI中包括的概率因子可以是预先配置的概率因子集合中的一个或多个概率因子。
本公开实施例中，第一用户设备在预知第二用户设备的情况下，第一用户设备可以在 第二用户设备的用户设备标识对应的概率因子集合中确定SCI中包括的概率因子，或者第一用户设备可以在第二用户设备所属小区的小区标识对应的概率因子集合中确定SCI中包括的概率因子。
另一种实施方式中，第一用户设备可以通过参考信号接收功率(Reference Signal Receiving Power，RSRP)阈值和/或两个用户设备发射信号和接收信号之间的角度值指定地理位置区域内的用户设备为第二用户设备。即第一用户设备发送RSRP阈值和/或两个用户设备发射信号和接收信号之间的角度值，以使其他用户设备基于RSRP阈值和/或角度值确定是否为提供辅助信息的第二用户设备。
一示例中，为使第二用户设备能够确定发送辅助信息的对象(第一用户设备)，第一用户设备可以发送第一用户设备的设备标识(assisted ID)
图4是根据一示例性实施例示出的一种基于辅助信息进行资源选择的方法的流程图，该基于辅助信息进行资源选择的方法可以单独被执行，也可以结合本公开的其他实施例一起被执行。如图4所示，基于辅助信息进行资源选择的方法由第一用户设备执行，包括以下步骤。
在步骤S31中，发送RSRP阈值，以及用户设备间发射信号和接收信号之间的角度值中的至少一种。
其中，RSRP阈值和/或角度值等字段信息可以包括在SCI中，例如可以包括在second stage SCI。
其中，RSRP阈值和/或角度值等字段信息，以广播形式发送，使得多个用户设备可以接收到。
一种实施方式中，本公开实施例预先配置RSRP阈值和/或角度值。例如，通过RRC预先配置参数集合。其中，网络设备可以基于用户设备标识，对每个用户设备预先配置参数集合。网络设备也可以基于小区标识，为每个小区预先配置参数集合。即，参数集合基于用户设备标识和/或小区标识确定，每一用户设备标识和/或小区标识具有对应的参数集合。
本公开实施例可以在预先配置的参数集合中确定RSRP阈值和/或角度值。即，用于确定第二用户设备的RSRP阈值和/或角度值可以是预先配置的参数集合确定的。
本公开实施例中，第一用户设备在预知第二用户设备的情况下，第一用户设备可以在第二用户设备的用户设备标识对应的参数集合中确定用于确定第二用户设备的RSRP阈值和/或角度值，或者第一用户设备可以在第二用户设备所属小区的小区标识对应的参数集合中确定用于确定第二用户设备的RSRP阈值和/或角度值。
本公开实施例又一种实施方式中，第一用户设备可以通过指示组播成员标识(member ID)确定第二用户设备。
可以理解的是，通过member ID确定第二用户设备的情况，需要基于第一用户设备与第二用户设备之间具有建立连接的通信。例如，第一用户设备和第二用户设备都是基于组播通信的用户设备。比如，第一用户设备和第二用户设备基于groupcast option2进行通信。
一示例中，为使第二用户设备能够确定发送辅助信息的对象(第一用户设备)，第一用户设备可以发送第一用户设备的设备标识(assisted ID)
图5是根据一示例性实施例示出的一种基于辅助信息进行资源选择的方法的流程图，该基于辅助信息进行资源选择的方法可以单独被执行，也可以结合本公开的其他实施例一起被执行。如图5所示，基于辅助信息进行资源选择的方法由第一用户设备执行，包括以下步骤。
在步骤S41中，发送member ID以及第一用户设备的assisted ID中的至少一种。
其中，member ID以及第一用户设备的assisted ID等字段信息可以包括在SCI中，例如可以包括在second stage SCI。
其中，member ID以及第一用户设备的assisted ID等字段信息，以广播形式发送，使得多个用户设备可以接收到。
一种实施方式中，本公开实施例member ID的数量为一个或多个。
一种实施方式中，member ID指示的第二用户设备可以是与第一用户设备同一组播中的用户设备，也可以是与第一用户设备不同组播中的用户设备。即，member ID指示的第二用户设备与第一用户设备位于同一组播中，或位于不同的组播中。
可以理解的是，本公开实施例中，第一用户设备发送SCI后，第二用户设备确定自身为提供辅助信息的用户设备后，第二用户设备为第一用户设备提供辅助信息，第一用户设备可以接收第二用户设备提供的辅助信息，并基于第二用户设备提供的辅助信息，进行资源选择。
进一步可以理解的是，本公开实施例中涉及的第二用户设备可以第一用户设备本次进行直连通信所发送直连通信数据的接收用户设备，也可以不是第一用户设备本次进行直连通信所发送直连通信数据的接收用户设备。
本公开实施例以下将对确定第二用户设备的过程进行说明。

一种实施方式中，控制信息可以为SCI，例如可以是second stage SCI。
在步骤S52中，基于控制信息中包括的字段信息，为第一用户设备提供辅助信息。
本公开实施例中接收到第一用户设备发送的控制信息的第二用户设备，可以基于控制信息中包括的用于确定第二用户设备的字段信息，确定是否为与第一用户设备基于辅助信息进行通信的第二用户设备。
本公开实施例中，用于确定第二用户设备的字段信息可以包括zone ID、概率因子以及第一用户设备的assisted ID。第二用户设备基于zone ID、概率因子以及第一用户设备的assisted ID，为第一用户设备提供辅助信息。
图7是根据一示例性实施例示出的一种基于辅助信息进行资源选择的方法的流程图，该基于辅助信息进行资源选择的方法可以单独被执行，也可以结合本公开的其他实施例一起被执行。如图7所示，基于辅助信息进行资源选择的方法由第二用户设备执行，包括以下步骤。
在步骤S61中，接收第一用户设备发送的zone ID，概率因子以及assisted ID中的至少一种。
在步骤S62中，向assisted ID所标识的第一用户设备提供辅助信息。其中，第二用户设备为第一用户设备发送的zone ID所标识区域内的用户设备，且随机生成的概率因子与第一用户设备发送的概率因子满足预设大小关系。
其中，随机生成的概率因子与SCI中携带的概率因子满足的预设大小关系，可以是随机生成的概率因子大于SCI中携带的概率因子，或者也可以是随机生成的概率因子等于SCI中携带的概率因子，或者也可以是随机生成的概率因子小于SCI中携带的概率因子。
一种实施方式中，用于确定第二用户设备的字段信息可以包括RSRP阈值和/或两个用户设备发射信号和接收信号之间的角度值，以及第一用户设备的assisted ID。

其中，RSRP测量值满足预先配置的RSRP阈值，比如RSRP_阈值1≤RSRP测量值≤RSRP_阈值2区域内的用户设备，作为第二用户设备。和/或满足预先配置的角度值的用户设备为第二用户设备。
一种实施方式中，用于确定第二用户设备的字段信息可以包括member ID以及第一用户设备的assisted ID。
图9是根据一示例性实施例示出的一种基于辅助信息进行资源选择的方法的流程图，该基于辅助信息进行资源选择的方法可以单独被执行，也可以结合本公开的其他实施例一起被执行。如图9所示，基于辅助信息进行资源选择的方法由第二用户设备执行，包括以下步骤。
在步骤S81中，接收第一用户设备发送的member ID以及assisted ID中的至少一种。
在步骤S82中，向接收到的assisted ID所标识的第一用户设备提供辅助信息。其中，第二用户设备的member ID与接收到的member ID相同。
可以理解的是，本公开实施例中，zone ID、概率因子以及assisted ID，或者RSRP阈值和/或角度值，以及assisted ID，或者member ID以及assisted ID，可以基于SCI接收，比如通过second stage SCI接收。
本公开实施例中，第二用户设备基于assisted ID确定了基于辅助信息进行资源选择的用户设备为第一用户设备的情况下，可以向第一用户设备提供辅助信息。第一用户设备基于接收到的辅助信息进行资源选择。
图10是根据一示例性实施例示出的一种基于辅助信息进行资源选择的方法的流程图，该基于辅助信息进行资源选择的方法可以单独被执行，也可以结合本公开的其他实施例一起被执行。如图10所示，基于辅助信息进行资源选择的方法由第一用户设备执行，包括以下步骤。
在步骤S91中，发送控制信息，控制信息中包括用于确定第二用户设备的字段信息。
其中，控制信息可以为second stage SCI。
其中，用于确定第二用户设备的字段信息可以包括zone ID以及概率因子。或者用于确定第二用户设备的字段信息可以包括RSRP阈值和/或两个用户设备发射信号和接收信号之间的角度值。或者用于确定第二用户设备的字段信息可以包括member ID。
进一步的，控制信息中还可以包括第一用户设备的assisted ID，以便确定的第二用户 设备能够确定提供辅助信息的对象为第一用户设备。
在步骤S92中，接收第二用户设备提供的辅助信息，并基于第二用户设备提供的辅助信息进行资源选择。
本公开实施例提供的基于辅助信息进行资源选择的方法，能够确定出提供辅助信息的用户设备。
本公开实施例以下以第一用户设备为UE-B，第二用户设备为UE-A为例对上述实施例涉及的基于辅助信息进行资源选择方法中确定UE-A的过程，进行进一步的说明。本公开实施例提供的确定UE-A的方式可包括如下方式一以及方式二。
方式一：UE-B指定一个地理位置区域内的UE为UE-A
一实施方式中，UE-B通过zone ID来指定UE-A。
UE-B通过新设计的SCI，例如新设计的second stage SCI来指定UE-A。
比如，在second stage SCI中携带zone ID字段、概率因子、assisted ID字段，该消息以广播形式发送出。
指定地理位置区域内的UE解码接收到的SCI。属于指示的zone ID区域内的UE，且随机生成的概率因子大于等于或小于等于SCI携带的概率因子的UE作为UE-A。UE-A根据SCI中的assisted ID字段发送辅助信息给对应的UE-B。
其中，UE-A可以是UE-B本次的直连通信数据(sidelink数据)的接收UE，也可以不是UE-B的本次sidelink数据的接收UE。
其中，概率因子由RRC预先配置的参数集合确定。参数集合是基站对每个UE预先配置的参数集合，可以理解为是针对UE预先配置的参数集合(UE specific preconfigure)。或基站对1个小区的UE预先配置的参数集合，可以理解为是针对小区预先配置的参数集合(cell preconfigure)。
其中，UE-A是UE-B的辅助UE，也可能是UE-C的辅助UE。故，需要根据assisted ID来区分UE-A发送给UE-B的辅助信息和UE-A发送给UE-C的辅助信息。即，SCI中携带的assisted ID，用来区分UE-A发送辅助信息的对象，UE-A根据该ID发送辅助信息给对应的UE-B。
图11是根据一示例性实施例示出的一种通过zone ID确定UE-A的示例图。参阅图11所示，假设UE-B在SCI中指定了zone ID为6，概率因子是0.5。指定的zone ID对应zone为6的区域内有UE3和UE4。UE3和UE4通过随机数生成概率因子，UE3生成的概率因子是0.6,UE4生成的概率因子是0.3，则UE-3的概率因子大于0.5，则UE3为UE-A。
另一实施方式中，UE-B通过RSRP阈值和/或角度值来指定UE-A。
其中，UE-B通过RSRP测量值和/或角度测量值，确定满足预先配置的[RSRP_阈值1≤RSRP测量值≤RSRP_阈值2]的区域内的UE，和/或满足预先配置的角度值的UE，以确定UE-A。
本公开实施例中，UE-B通过设计的新的SCI来携带RSRP阈值和/或角度值字段，assisted ID字段等。
其中，RSRP阈值和角度值是预先配置的。例如，RRC预先配置一个参数集合。示例的，基站对每个UE预先配置(UE specific preconfigure)参数集合或基站对每个小区的UE预先配置参数集合(cell preconfigure)。
其中，assisted ID，用来区分UE-A发送辅助信息的对象，UE-A根据该assisted ID发送辅助信息给对应的UE-B。比如，UE-A是UE-B的辅助UE，也可能是UE-C的辅助UE。故，需要根据assisted ID来区分UE-A发送给UE-B的辅助信息和UE-A发送给UE-C的辅助信息。
图12是根据一示例性实施例示出的一种通过RSRP阈值和/或角度值确定UE-A的示例图。参阅图12所示，在R16中的mode2的资源感知中，UE-B通过接收其他UE的SCI或者数据，进行物理直连控制信道(Physical Sidelink Control Channel，PSCCH)的解调参考信号(Demodulation Reference Signal，DMRS)的RSRP测量或者进行物理直连共享信道(Physical Sidelink Share Channel，PSSCH)的DMRS的RSRP测量。UE-B获得周围UE的RSRP测量值。其中，UE2的RSRP测量值在预先定义的[RSRP_阈值1≤RSRP测量值≤RSRP_阈值2]阈值范围内。
其中，对于UE-B测量角度。在实现上，UE-B通过已有的定位的方式，如使用positioning中测量角度的方法，得到其周围UE的角度测量值。比如预先配置的角度集合，{0，1/2π，π，3/2π，2π}，在SCI中携带的角度测量值为2比特，11指示的为2π。UE-B测量到的UE2的角度值为2π。故，UE2既满足RSRP阈值，又满足角度值，UE2是辅助UE-A。
方式二：UE-B通过指示member ID来确定UE-A
其中，通过指示member ID来确定UE-A的方式可以适用于groupcast option2的组播通信中。
本公开实施例中，UE-B可以在新设计的second stage SCI中携带member ID和assisted ID等字段，并以广播形式发送出去。其中，可以理解的是second stage SCI中携带的member ID指示的UE是UE-A。
其中，UE-B广播的second stage SCI中携带的member ID可以是1个或多个member ID。
进一步的，member ID指示的UE可以和UE-B是同一个组，也可以与UE-B不是同一 个组的UE。
UE-B广播的second stage SCI中携带的assisted ID，用来区分UE-A发送辅助信息的对象，UE-A根据该assisted ID发送辅助信息给对应的UE-B。其中，assisted ID可以是UE-B的source ID或其他ID。
接收到UE-B广播的second stage SCI的UE，解码second stage SCI，得到member ID。解码得到的member ID与自身member ID相同的UE作为辅助UE-A。UE-A根据SCI中的assisted ID字段发送辅助信息给对应的UE-B。
图13是根据一示例性实施例示出的一种通过member ID来确定UE-A的示例图。参阅图13所示，在组播中，UE-B在SCI中携带的member ID。假设在SCI中携带的member ID对应的是member ID为1的UE，那么与UE-B在同一个组内的member ID为1的UE2，和其他组里member ID为1的另外1个UE都是UE-A，根据assisted ID向UE-B发送辅助信息的。
本公开实施例中，第一设备发送的控制信息中包括用于确定第二用户设备的字段信息，通过该字段新可以确定出提供辅助信息的第二用户设备，进而可以实现终端间基于辅助信息进行资源选择的通信方法。
可以理解的是，本公开实施例提供的基于辅助信息进行资源选择的方法，适用于用户设备间进行交互通信的场景，也适用于用户设备与网络设备交互通信的场景，具体实施过程与上述实施例类似，故在此不再详述。
需要说明的是，本领域内技术人员可以理解，本公开实施例上述涉及的各种实施方式/实施例中可以配合前述的实施例使用，也可以是独立使用。无论是单独使用还是配合前述的实施例一起使用，其实现原理类似。本公开实施中，部分实施例中是以一起使用的实施方式进行说明的。当然，本领域内技术人员可以理解，这样的举例说明并非对本公开实施例的限定。
基于相同的构思，本公开实施例还提供一种基于辅助信息进行资源选择的装置。
可以理解的是，本公开实施例提供的基于辅助信息进行资源选择的装置为了实现上述功能，其包含了执行各个功能相应的硬件结构和/或软件模块。结合本公开实施例中所公开的各示例的单元及算法步骤，本公开实施例能够以硬件或硬件和计算机软件的结合形式来实现。某个功能究竟以硬件还是计算机软件驱动硬件的方式来执行，取决于技术方案的特定应用和设计约束条件。本领域技术人员可以对每个特定的应用来使用不同的方法来实现所描述的功能，但是这种实现不应认为超出本公开实施例的技术方案的范围。
