Description

资源选择方法、资源选择装置及存储介质 技术领域

新一代的新型互联网应用的不断涌现对于无线通信技术提出了更高的要求，驱使无线通信技术的不断演进以满足应用的需求。
随着新一代5G移动通信技术的发展，在3GPP Rel-16中利用5G新无线(New Radio，NR)技术实现了对直连通信服务和场景的支持。例如，对新的车用无线通信技术(Vehicle to Everything，V2X)通信服务和场景的支持。
相关技术中，直连通信资源池包含了用户设备进行直连通信所使用的时间频率资源，分为Tx资源池和Rx资源池。用户设备在Tx资源池里进行信道监听和资源选择，并在Rx资源池里进PSCCH盲检测和数据接收。相关技术中，对于直连通信的用户设备A可以发送资源集合给资源选择方式为Mode2的用户设备B，用户设备B在为自己的数据传输进行资源选择时加以考虑。用户设备间需进行资源的协调，然而在Rel-16 V2x中，一个用户设备可以被配置多个不同的Tx资源池和/或Rx资源池。当用户设备被配置或者被预配置多个Tx资源池的时候，如何有效的进行用户间协调是需要解决的技术问题。

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资源选择方法可应用于图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。
车联网可以有效提升交通安全，改善交通效率以及丰富人们的出行体验。利用已有蜂窝通信技术支持车联网通信可以有效利用现有基站部署，减少设备开销，也更有利于提供具有QoS保证的服务，满足车联网业务的需求。因此，在长期演进(Long Term Evolution，LTE)Rel-14/15中提供了蜂窝网络对于车联网V2x通信的支持，即蜂窝车用无线通信技术(Cellular-Vehicle to Everything，C-V2X)。在C-V2x中，车载设备和其他设备之间的通信可以通过基站以及核心网进行中转，即利用原有蜂窝网络中终端设备和基站之间的上下行链路进行通信；也可以直接通过设备之间的直连链路进行通信。与Uu接口通信相比，sidelink通信具有时延短，开销小等特点，非常适合用于车载设备和地理位置接近的其他周边设备直接的通信。
直连通信设备之间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。
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。
R16 NR sidelink中，假设所有直连用户设备使用相同的sidelink带宽部分(Bandwidth Part，BWP)，并在BWP上定义资源池。直连通信资源池包含了用户设备进行直连通信所使用的时间频率资源，分为发送资源池(Tx资源池)和接收资源池(Rx资源池)。用户设备在Tx资源池里进行信道监听和资源选择，并在Rx资源池里进行物理直连控制信道(Physical Sidelink Control Channel，PSCCH)盲检测和数据接收。在Rel-16 V2x中，一个用户设备可以被配置多个不同的Tx资源池和/或Rx资源池。
基于Rel16 V2x的技术，Rel17 Sidelink会继续讨论如何进一步通过用户间协调的方法减少延迟，增加直连通信可靠性。Rel-17 NR中正在讨论通过用户间协作增加Mode2资源选择的可靠性或者减少时延。提出的一种方法是由用户设备A发送一个资源集合给用户设备B，用户设备B在进行资源选择的时候，将用户设备A发送的资源集合纳入考虑。例如，用户设备A可以根据信道监听的结果，判断哪些资源适合用户设备B直连通信使用，或者不适合用户B直连通信使用，并将这些资源指示给用户设备B。用户设备B综合自身信道监听和用户设备A信道监听的结果进行资源选择，可以增加资源选择的可靠性。
然而，上述进行用户间协作方式进行资源协调的方案中，是基于用户设备A和用户设备B都设置一个Tx资源池的假设。当用户设备A和/或用户设备B被配置的资源池大于一个时，用户设备A和用户设备B之间如何进行有效的资源协调并没有讨论。
本公开实施例提供一种资源选择方法，在该资源选择方法中，响应于用户设备被配置了多个直连资源池(大于一个直连资源池)，在用户设备间基于多个直连资源池进行资源的协调。
本公开实施例中为描述方便将进行直连通信的设备称为第一设备和第二设备。其中，第一设备可以是基于第二设备发送的辅助时间频率资源进行资源选择的用户设备，例如上述示例中的用户设备B。第二设备可以理解为是提供辅助时间频率资源的用户设备，例如上述示例中的用户设备A。其中，第一设备可以被配置多个直连资源池。和/或，第二设备也可以被配置多个直连资源池。
可以理解的是，第一设备和/或第二设备被配置的多个直连资源池可以是Tx资源池，也可以是Rx资源池。其中，多个直连资源池可以是配置在相同BWP或者载频上的资源池，也可以是不同BWP或载频上的资源池。
进一步的，本公开实施例中将第二设备发送的并用于指示辅助第一设备进行资源选择 时考虑的辅助时间频率资源集合的控制信令，称为第一直连控制信令。其中，第一直连控制信令可能是物理层直连控制信令，媒体接入控制(Media Access Control，MAC)层直连控制信令，或者无线资源控制(Radio Resource Control，RRC)层直连控制信令。
进一步的，本公开实施例中将第二设备发送第一直连控制信令的资源池称为第一直连资源池。将辅助第一设备进行资源选择的辅助时间频率资源集合所属的直连资源池称为第二直连资源池。将第二设备选择直连传输资源的直连资源池称为第三直连资源池。
图2是根据一示例性实施例示出的一种资源选择方法的流程图，如图2所示，资源选择方法用于第一设备中，包括以下步骤。

用户设备A通过某种特定规则确定Tx资源池，例如选择根据Tx资源池配置的顺序确定Tx资源池，或者在多个Tx资源池间进行随机选择，或者根据待传输数据的优先级信息确定对应的Tx资源池；

-如果所述直连控制信令的发送是通过接收用户设备B发送的另一直连控制控制信令(信令2)所激发的，采用如下方式确定信令2传输所使用的Tx资源池；
用户设备B按照配置或者预配置的Tx资源池或者用于协调信令传输的Tx资源池确定所述时间频率资源集合所属的Tx资源池或资源池集合；
用户设备B通过某种特定规则确定Tx资源池，例如选择根据Tx资源池配置的顺序确定Tx资源池，或者在多个Tx资源池间进行随机选择，或者根据待传输数据的优先级信息确定对应的Tx资源池；
用户设备B按照信道监听或者信道/信号测量的结果选择Tx资源池或资源池集合；例如：根据CBR(Channel busy ratio)测量值进行选择，如选择CBR测量值最小或者小于一定阈值(即拥塞情况较好)的Tx资源池。
