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申请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、本申请的一些方面相一 致的装置和方法的例子。
本申请实施例的技术方案可以适用于各种通信***，例如：长期演进(Long Term Evolution，LTE)***、LTE频分双工(Frequency Division Duplex，FDD)***、LTE时分双工(Time Division Duplex，TDD)、通用移动通信***(Universal Mobile Telecommunication System，UMTS)、全球互联微波接入(Worldwide Interoperability for Microwave Access，WiMAX)通信***、5G移动通信***或新无线接入技术(New Radio Access Technology，NR)。其中，5G移动通信***可以包括非独立组网(Non-Standalone，NSA)和/或独立组网(Standalone，SA)。
本申请提供的技术方案还可以适用于机器类通信(Machine Type Communication，MTC)、机器间通信长期演进技术(Long Term Evolution-Machine，LTE-M)、设备到设备(Device-to Device，D2D)网络、机器到机器(Machine to Machine，M2M)网络、物联网(Internet of Things，IoT)网络或者其他网络。其中，IoT网络例如可以包括车联网。其中，车联网***中的通信方式统称为车到其他设备(Vehicle to X，V2X，X可以代表任何事物)，例如，该V2X可以包括：车辆到车辆(Vehicle to Vehicle，V2V)通信，车辆与基础设施(Vehicle to Infrastructure，V2I)通信、车辆与行人之间的通信(Vehicle to Pedestrian，V2P)或车辆与网络(Vehicle to Network，V2N)通信等。
首先对本申请涉及的相关术语或名词进行介绍，以便于本领域技术人员理解。
(1)Sidelink
Sidelink用于终端设备之间的直接通信，具体的，终端设备与终端设备之间可以通过直连通信接口使用Sidelink通信。在资源池中，时域上的最小粒度为时隙(Slot)，频域上的最小粒度为子信道(Subchannel)，一个子信道包含多个资源块(Resource Block，RB)。终端设备在进行Sidelink传输资源选择时，可根据其需要传输的数据包的大小，确定所需的子信道的个数X，从而确定该终端设备的Sidelink传输资源为某个时隙中连续的X个子信道，X为正整数，图1为子信道的个数为3的示意图，该Sidelink传输资源上同时传输边缘通信物理控制信道(Physical Sidelink Control CHannel，PSCCH)和边缘通信共享信道(Physical Sidelink Shared Channel，PSSCH)。其中，PSCCH承载侧行链路控制信息(Sidelink Control Information，SCI)，PSSCH承载传输的数据，SCI包括当前Sidelink传输资源的时频域位置信息、预留的Sidelink传输资源的时频域位置信息以及解码PSSCH的参数等，其中预留的Sidelink传输资源可称为预留资源。
在NR V2X中，支持模式1(Mode 1)和模式2(Mode 2)两种Sidelink资源分配方案。
Mode 1：基站调度Sidelink传输资源给终端设备进行Sidelink传输。
Mode 2：终端设备确定由基站/网络设备配置或预配置的Sidelink传输资源，即基站不参与资源分配。以下Sidelink传输资源可以称为传输资源。
在Mode 2下的资源分配可以分为资源感知、以及资源选择/重选阶段，分别对应资源感知窗口和资源选择窗口。终端设备一直处于资源感知的状态，当终端设备触发资源选择，终端设备根据资源感知窗口的感知结果，判断资源选择窗内的资源占用情况，排除资源选择窗内被其他中的设备占用的不可用资源，以确定可用的传输资源进行Sidelink传输。终端设备触发资源选择的触发条件可以有多种，示例性的，触发条件可以是当数据包到达时，终端设备没有可用的传输资源。
具体的，在资源感知窗口中，当终端设备检测到PSCCH，则对PSCCH中承载的SCI进行解码，并通过接收到的参考信号接收功率(Reference Signal Received Power，RSRP)进行判断，如图2所示，终端设备A和终端设备B的RSRP的值小于或者等于预设的功率阈值，则确定终端设备A和终端设备B在资源选择窗内的预留资源为可用资源，其中，终端设备A和终端设备B的预留资源的时频域位置信息可以通过解码SCI得到。
(2)SCI
SCI中的预留资源的时频域位置信息(即时域位置信息和频域位置信息)，是终端设备在传输同一个传输块(Transport Block，TB)时，指示该TB的重传传输资源，以表示资源预留，当其他终端设备感知到该终端设备当前的传输资源后，可以根据SCI确定资源选择窗内的预留资源的占用情况。其中，TB包括PSCCH和PSSCH。
每个SCI中最多可以指示L个传输资源，示例性的，可通过高层信令配置一个资源池中支持的L的值，该值一般为2或者3，也就是说，SCI中需要指示本次传输以及其他最多2次重传的时频域资源位置。为了限制SCI中的资源指示开销，每个SCI中指示的第一个传输资源和最后一个传输资源的时间间隔不超过32个时隙。如图3所示，当L的值为3，从时域上看，那么表示一次传输的SCI中可以最多指示后面两个重传资源，也就是说，第一次TB传输的SCI中指示本次传输和后面两次TB重传的时频域资源位置，第二次TB传输的SCI指示本次传输和第三次传输的时频域资源位置。可以理解，第三次传输中的SCI 中不再指示后续的传输资源。一般的，一个TB的传输次数(包括初次传输和重传)最大值可以为32。其中，SCI中的时域位置信息和频域位置信息可以采用联合编码的方式表示。
(3)定位参考信号(Positioning Reference Signal，PRS)
在移动通信***中，对终端设备进行定位是重要的功能之一。当前的定位技术包括下行定位技术和上行定位技术，下行参考信号可以为PRS。终端设备可以通过Sidelink传输资源发送PRS，使得其他终端设备可以对该PRS进行测量，以获取终端设备之间的相对位置。
可以理解，PRS可以与PSCCH和/或PSSCH等信息一起在sidelink传输资源上传输，或者，PSCCH和PSSCH等信息传输的资源池与PRS传输对应的资源池可以在不同的频点、不同载波或者不同的部分带宽(Bandwidth Part，BWP)。由于PRS的带宽较大，若按照上述Sidelink的资源分配方案确定PRS的传输资源，则在时域上，一个时隙仅能分配给一个终端设备使用，而频域上可以占用整个资源池带宽，使得PRS的传输资源较为紧缺，如何提高PRS的传输资源的利用效率是需要解决的一个问题。
具体的，PRS的参数结构包括四层结构，即一个定位频率层包含多个发送接收点(Transmission and Reception Point，TPR)，一个TPR可以对应多个PRS资源集(Set)，一个PRS资源集可以包含多个PRS资源。其中，每个PRS资源均有对应的标识(Identity Document，ID)。
相应的，每一层对应的参数以及作用范围不同，示例性的，定位频率层的参数包含PRS的频域资源参考位置、PRS的子载波间隔、PRS的循环前缀(Cyclic Prefix，CP)类型、PRS的资源图样、PRS的起始资源块(Resource Block，RB)以及PRS的带宽。定位频率层的作用范围是该层内包含的所有的PRS资源。
PRS资源集层的参数包含PRS资源的周期、PRS资源集的起始时隙、PRS资源的重复因子、PRS资源之间的时间间隔以及PRS传输的静音图样。PRS资源集层的作用范围是该资源集内的所有的PRS资源。
PRS资源层的参数包含PRS所占第一个符号的起始RE位置、相对于第一个符号的RE位置间隔、PRS相对于PRS资源集第一个时隙的间隔(间隔单位为时隙)、PRS起始符号(Symbol)的位置以及所占的符号数。PRS资源层的作用范围是该层内的所有的PRS资源。
有鉴于此，本申请提供了一种资源分配方法，终端设备根据资源池的资源配置参数确定至少一个PSCCH频域资源范围，通过在至少一个PSCCH频域资 源范围内进行SCI盲检，以确定多个SL-PRS资源中可用的PRS的传输资源，不再需要分配一个时隙给一个终端设备进行PRS的传输，有助于缓解资源紧缺的问题，提高了资源池的资源的利用率。
对于Sidelink的通信场景，可分为终端设备均在基站覆盖范围内(In-Coverage)、部分终端设备处于基站覆盖范围内(Partial-Coverage)、以及终端设备均超出基站覆盖范围内(Out-of-Coverage)，如图4A、图4B和图4C所示。
本申请实施例所适用的应用场景可以为上述任意一个通信场景，下面以图4C为例进行说明。
参见图4C，包括终端设备401和终端设备402。终端设备401和终端设备402通过直连通信接口(例如PC5)进行通信，终端设备401根据资源配置参数确定PSCCH频域资源范围，并在PSCCH频域资源范围进行PSCCH检测，以进行SCI盲检，使得终端设备401可用根据盲检结果确定终端设备402发送的SCI信息中指示的可用的PRS的传输资源。
可以理解，终端设备401和终端设备402的数量均可以为多个，图中未示出。终端设备401和终端设备402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)终端设备、增强现实(Augmented Reality，AR)终端设备、工业控制(Industrial Control)中的无线终端、车辆终端设备、无人驾驶(Self Driving)中的无线终端、路侧设备(Road Side Unit，RSU)、远程医疗(Remote Medical)中的无线终端设备、智能电网(Smart Grid)中的无线终端设备、运输安全(Transportation Safety)中的无线终端设备、智慧城市(Smart City)中的无线终端设备、智慧家庭(Smart Home)中的无线终端设备、可穿戴终端设备等。本申请实施例所涉及的终端设备还可以称为终端、用户设备(User Equipment，UE)、接入终端设备、车辆终端、工业控制终端、UE单元、UE站、移动站、移动台、远方站、远程用户设备、移动设备、无线通信设备、UE代理或UE装置等。
图4A-4C中的基站是一种具有无线收发功能的设备。包括但不限于：LTE中的演进型基站(Evolutional Node B，eNB或eNodeB)、NR中的基站(gNodeB或gNB)或收发节点(Transmission and Receiving Points，TRP)、后续演进***中的基站、无线保真(Wireless Fidelity，WiFi)***中的接入节点、无线中继节点、无线回传节点等。基站可以是：宏基站、微基站、微微基站、小站、中继站等。
下面以具体地实施例对本申请的技术方案以及本申请的技术方案如何解决上述技术问题进行详细说明。下面这几个具体的实施例可以独立存在，也可以相互结合，对于相同或相似的概念或过程可能在某些实施例中不再赘述。下面将结合附图，对本申请的实施例进行描述。
图5为本申请实施例一提供的一种资源分配方法的流程示意图，该方法可以由终端设备执行，参考图5，该方法包括如下步骤。
S501、终端设备获取资源池的资源配置参数。
终端设备可以获取资源池的资源配置参数，该资源池可用于传输PRS，可以理解，该资源池也可以用于终端设备传输PSCCH和PSSCH等信息，本申请对此不作限制。
需要说明的是，资源配置参数可以是终端设备根据其预定义规则确定的，也可以是由终端设备的高层信令预配置的，终端设备通过高层信令获取该资源配置参数。或者，资源配置参数也可以由网络设备(例如基站)配置，并发送给终端设备。
S502、终端设备根据资源配置参数，确定资源池频域上至少一个PSCCH频域资源范围。
终端设备获取到资源配置参数后，可以根据资源配置参数确定该资源池频域上至少一个PSCCH频域资源范围。
进一步的，资源配置参数的不同，确定的至少一个PSCCH频域资源范围的方式不同，示例性的，当资源配置参数中包括每个时隙中SL-PRS资源的配置参数，则表示每个时隙中包括多个SL-PRS资源，那么，终端设备可以在每个时隙中确定的至少一个PSCCH频域资源范围，从而终端设备根据SL-PRS资源与PSCCH频域资源范围的映射方式，确定每个PSCCH频域资源范围关联的SL-PRS资源。
S503、终端设备在至少一个PSCCH频域资源范围进行SCI盲检，以确定资源池中可用的PRS的传输资源。
终端设备可以在至少一个PSCCH频域资源范围进行SCI盲检，根据盲检结果，确定可用的PRS的传输资源。
示例性的，当资源配置参数中包括每个时隙中SL-PRS资源的配置参数，则终端设备用于SCI盲检的每个PSCCH频域资源范围，均关联至少一个SL-PRS资源，那么，终端设备根据盲检结果，可以确定至少一个PSCCH频域资源范围中每个PSCCH频域资源范围关联的SL-PRS资源是否可用，以实现一个时隙中 可以有至少一个SL-PRS资源提供给多个终端设备进行PRS的传输。
示例性的，上述盲检结果可以是RSRP的值，当RSRP的值小于或者等于预设的功率阈值，则确定相应的PSCCH频域资源范围关联的SL-PRS资源可用，可以理解，可用的SL-PRS资源可以是其他终端设备在资源选择窗内的预留资源。
在本实施例中，终端设备通过获取资源池的资源配置参数，根据该资源配置参数确定资源池频域上至少一个PSCCH频域资源范围，并在至少一个PSCCH频域资源范围进行SCI盲检，使得根据SCI盲检结果确定资源池中可用的PRS的传输资源，不再需要分配一个时隙给一个终端设备进行PRS的传输，有助于缓解资源紧缺的问题，提高了资源池的资源的利用率。
资源配置参数不同，相应的，PSCCH频域资源范围的确定方式也有所不同，示例性的，可分为四种确定方式。下面以四种确定方式为例，通过实施例二至实施例五分别对终端设备根据四种确定方式确定PSCCH频域资源范围进行详细说明。
本申请实施例二提供的一种PSCCH频域资源范围的确定方法，该方法可以由终端设备执行。
资源配置参数包括以下一个或多个参数：每个时隙中至少一个SL-PRS资源的配置参数、每个PSCCH频域资源范围关联的SL-PRS资源的个数N，N为正整数。
其中，SL-PRS资源的配置参数可以包括：SL-PRS的起始符号位置、SL-PRS占用的符号数、SL-PRS的资源单元偏移值、SL-PRS的资源图样、以及SL-PRS所占用的频域子信道个数或资源块个数。
终端设备可以基于上述资源配置参数中的每个PSCCH频域资源范围关联的SL-PRS资源的个数N，以及每个时隙配置的SL-PRS资源个数，划分资源池的频域资源，以确定至少一个PSCCH频域资源范围的资源大小。示例性的，当N为2，每个时隙配置的SL-PRS资源个数为8，资源池的带宽为24个子信道，则根据N和SL-PRS资源个数8，如图6所示，可以确定4个PSCCH频域资源范围，那么每个PSCCH频域资源范围的资源大小为6个子信道，图中已按照频域位置由低到高排序。
进一步的，终端设备可以根据每个PSCCH频域资源范围的资源大小、SL-PRS资源的配置参数、SL-PRS资源与PSCCH频域资源范围的映射方式，在资源池频域上确定每个SL-PRS资源关联的PSCCH频域资源范围。
可选的，上述映射关系为根据SL-PRS资源的索引号，以及至少一个PSCCH 频域资源范围频域位置，依次进行SL-PRS资源与PSCCH频域资源范围的映射。具体的，上述映射关系可以是根据SL-PRS资源的索引号由小到大，以及至少一个PSCCH频域资源范围频域位置由低到高，依次进行SL-PRS资源与PSCCH频域资源范围的映射。
以4个PSCCH频域资源范围为例，4个PSCCH频域资源范围频域位置由低到高排列为：PSCCH频域资源范围1，…，PSCCH频域资源范围4。每个时隙配置的8个SL-PRS资源按照索引号从小到大进行排列为：SL-PRS1，SL-PRS2，…，SL-PRS8。则按照SL-PRS资源与PSCCH频域资源范围的映射方式，按照SL-PRS资源的索引号从小到大，将每两个SL-PRS资源按照PSCCH频域资源范围的频域位置由低到高依次进行SL-PRS资源与PSCCH频域资源范围的映射，即将SL-PRS1与SL-PRS2与PSCCH频域资源范围1进行映射，将SL-PRS3与SL-PRS4与PSCCH频域资源范围2进行映射，将SL-PRS5与SL-PRS6与PSCCH频域资源范围3进行映射，将SL-PRS7与SL-PRS8与PSCCH频域资源范围4进行映射，也就是说，将每两个SL-PRS资源与PSCCH频域资源范围进行关联，以具备关联关系，从而使得终端设备可以根据PSCCH频域资源范围内进行SCI盲检的盲检结果，确定与PSCCH频域资源范围关联的SL-PRS资源是否可用。
具体的，在资源池频域上确定每个SL-PRS资源关联的PSCCH频域资源范围后，根据SL-PRS资源的配置参数，可以确定SL-PRS资源的起始符号位置、占用的符号数、资源单元偏移值、资源图样以及所占用的频域子信道个数或资源块个数等，使得当确定SL-PRS资源可用时，终端设备使用该SL-PRS资源进行PRS传输。
在本实施例中，终端设备根据资源配置参数划分资源池的频域资源，确定PSCCH频域资源范围的资源大小以及位置后，按照SL-PRS资源与PSCCH频域资源范围的映射方式将一个时隙中的SL-PRS资源与PSCCH频域资源范围进行映射，从而使得终端设备可以根据PSCCH频域资源范围内进行SCI盲检的盲检结果，确定与PSCCH频域资源范围关联的SL-PRS资源是否可用。不再需要分配一个时隙给一个终端设备进行PRS的传输，有助于缓解资源紧缺的问题，提高了资源池的资源的利用率。
本申请实施例三提供的另一种PSCCH频域资源范围的确定方法，该方法可以由终端设备执行。
资源配置参数包括以下一个或多个参数：每个时隙中至少一个SL-PRS资源 的配置参数、PSCCH频域资源范围的个数P、每个PSCCH频域资源范围的资源大小、第一个PSCCH频域资源范围的起始位置以及相邻两个PSCCH频域资源范围的频域间隔，其中P为大于或等于1的整数。
其中，SL-PRS资源的配置参数可以包括：SL-PRS的起始符号位置、SL-PRS占用的符号数、SL-PRS的资源单元偏移值、SL-PRS的资源图样以及SL-PRS所占用的频域子信道个数或资源块个数。
终端设备可以基于上述资源配置参数中的每个PSCCH频域资源范围的资源大小、PSCCH频域资源范围的个数P、第一个PSCCH频域资源范围的起始位置以及相邻两个PSCCH频域资源范围的频域间隔，确定至少一个PSCCH频域资源范围的位置。
作为一种可能的实现方式，终端设备也可以根据每个时隙配置的SL-PRS资源个数确定PSCCH频域资源范围的个数P，即每个时隙配置的SL-PRS资源个数可以等于PSCCH频域资源范围的个数P。
示例性的，第一个PSCCH频域资源范围的起始位置可以是起始资源块或者起始子信道的编号，例如第一个PSCCH频域资源范围的起始子信道的编号为0，由于一个子信道包括多个资源块，所以不限定第一个PSCCH频域资源范围的起始位置为子信道0中的某个资源块，也就是说，整个子信道0均可作为第一个PSCCH频域资源范围的起始位置。PSCCH频域资源范围的个数P的值为3，相邻两个PSCCH频域资源范围的频域间隔为2个子信道，则终端设备确定3个PSCCH频域资源范围的位置如图7所示，图中已按照频域位置由低到高排序。
进一步的，终端设备可以根据每个时隙配置的SL-PRS资源个数和PSCCH频域资源范围的个数P，确定一个PSCCH频域资源范围对应的SL-PRS资源的个数，示例性的，当每个时隙配置的SL-PRS资源个数为3，P为3，则确定一个PSCCH频域资源范围对应的一个SL-PRS资源。
进一步的，终端设备可以根据至少一个PSCCH频域资源范围的位置、SL-PRS资源的配置参数、SL-PRS资源与PSCCH频域资源范围的映射方式，以及一个PSCCH频域资源范围对应的SL-PRS资源的个数，在资源池频域上确定每个SL-PRS资源关联的PSCCH频域资源范围。
以图7为例，3个PSCCH频域资源范围按照频域位置由低到高排序为：PSCCH频域资源范围1，PSCCH频域资源范围2，PSCCH频域资源范围3。每个时隙配置的3个SL-PRS资源按照索引号由小到大排序为：SL-PRS1，SL-PRS2，SL-PRS3。终端设备可以按照SL-PRS资源与PSCCH频域资源范围的映射方式， 将SL-PRS1与PSCCH频域资源范围1进行映射，将SL-PRS2与PSCCH频域资源范围2进行映射，将SL-PRS3与PSCCH频域资源范围3进行映射。也就是说，将每个SL-PRS资源与每个PSCCH频域资源范围进行关联，以具备关联关系，从而使得终端设备可以根据PSCCH频域资源范围内进行SCI盲检的盲检结果，确定与PSCCH频域资源范围关联的SL-PRS资源是否可用。
在另一个示例中，第一个PSCCH频域资源范围的起始子信道的编号为2，PSCCH频域资源范围的个数P的值为2，相邻两个PSCCH频域资源范围的频域间隔为2个子信道，则终端设备确定2个PSCCH频域资源范围的位置如图8所示。进一步的，终端设备可以根据每个时隙配置的SL-PRS资源个数4和PSCCH频域资源范围的个数2，确定一个PSCCH频域资源范围对应的2个SL-PRS资源。
2个PSCCH频域资源范围按照频域位置由低到高排序为：PSCCH频域资源范围1，PSCCH频域资源范围2，每个时隙配置的4个SL-PRS资源按照索引号由小到大排序为：SL-PRS1，SL-PRS2，SL-PRS3，SL-PRS4。如图8所示，终端设备按照SL-PRS资源与PSCCH频域资源范围的映射方式、将SL-PRS1和SL-PRS2均与PSCCH频域资源范围1进行映射，将SL-PRS3和SL-PRS4均与PSCCH频域资源范围2进行映射。也就是说，将每两个SL-PRS资源与每个PSCCH频域资源范围进行关联，以具备关联关系。
在又一个示例中，第一个PSCCH频域资源范围的起始子信道的编号为2，PSCCH频域资源范围的个数P的值为2，相邻两个PSCCH频域资源范围的频域间隔为2个子信道，则终端设备确定2个PSCCH频域资源范围的位置如图9所示。进一步的，终端设备可以根据每个时隙配置的SL-PRS资源个数5和PSCCH频域资源范围的个数2，终端设备可以通过SL-PRS资源的个数M与PSCCH频域资源范围的个数N的比值，并且向上取整，确定一个PSCCH频域资源范围关联的SL-PRS资源的个数，即一个PSCCH频域资源范围对应的SL-PRS资源个数等于那么，在该示例中，终端设备可以确定一个PSCCH频域资源范围对应的3个SL-PRS资源。
2个PSCCH频域资源范围按照频域位置由低到高排序为：PSCCH频域资源范围1，PSCCH频域资源范围2，每个时隙配置的5个SL-PRS资源按照索引号由小到大排序为：SL-PRS1，SL-PRS2，…，SL-PRS5。如图9所示，终端设备按照SL-PRS资源与PSCCH频域资源范围的映射方式、将SL-PRS1、SL-PRS2和SL-PRS3均与PSCCH频域资源范围1进行映射，将SL-PRS4和SL-PRS5均 与PSCCH频域资源范围2进行映射。也就是说，将前三个SL-PRS资源与第一个PSCCH频域资源范围进行关联，将后两个SL-PRS资源与第二个PSCCH频域资源范围进行关联，以具备关联关系。
对于SL-PRS资源与PSCCH频域资源范围的映射方式的描述，可以参考实施例二，这里不再赘述。
具体的，在资源池频域上确定每个SL-PRS资源关联的PSCCH频域资源范围后，根据SL-PRS资源的配置参数，可以确定SL-PRS资源的起始符号位置、占用的符号数、资源单元偏移值、资源图样以及所占用的频域子信道个数或资源块个数等，使得当确定SL-PRS资源可用时，终端设备使用该SL-PRS资源进行PRS传输。
在本实施例中，终端设备根据资源配置参数划分资源池的频域资源，确定PSCCH频域资源范围的位置和资源大小后，按照SL-PRS资源与PSCCH频域资源范围的映射方式将一个时隙中的SL-PRS资源与PSCCH频域资源范围进行映射，从而使得终端设备可以根据PSCCH频域资源范围内进行SCI盲检的盲检结果，确定与PSCCH频域资源范围关联的SL-PRS资源是否可用。不再需要分配一个时隙给一个终端设备进行PRS的传输，有助于缓解资源紧缺的问题，提高了资源池的资源的利用率。
需要说明的是，对于上述实施例中的SL-PRS资源与PSCCH频域资源范围的映射方式，本申请实施例仅为示例，SL-PRS资源与PSCCH频域资源范围的映射方式还可以是其他的映射方式，例如可以是根据SL-PRS资源的索引号由大到小，以及至少一个PSCCH频域资源范围频域位置由低到高，依次进行SL-PRS资源与PSCCH频域资源范围的映射。又例如，SL-PRS资源与PSCCH频域资源范围的映射方式还可以是将SL-PRS资源与任意一个或者多个PSCCH频域资源范围进行映射，本申请对此不作限定。
本申请实施例四提供的另一种PSCCH频域资源范围的确定方法，该方法可以由终端设备执行。
资源配置参数包括以下一个或者多个参数：PSCCH频域资源范围的起始位置和PSCCH频域资源范围的资源大小。对于PSCCH频域资源范围的起始位置的描述，可以参考实施例三，这里不再赘述。
进一步的，终端设备可以根据PSCCH频域资源范围的起始位置和PSCCH频域资源范围的资源大小，确定资源池频域上至少一个PSCCH频域资源范围，如图10所示，图10为确定的一个PSCCH频域资源范围的示意图。
作为一种可能的实现方式，终端设备还可以根据资源池的资源大小，以及PSCCH频域资源范围的资源大小，确定多个PSCCH频域资源范围。示例性的，当资源池的资源大小为64个子信道，PSCCH频域资源范围的资源大小为8个子信道，则终端设备可以确定8个PSCCH频域资源范围。使得终端设备可以在至少一个PSCCH频域资源范围内进行SCI盲检，根据SCI盲检结果，确定可用的PRS的传输资源。
在本实施例中，终端设备根据资源配置参数确定至少一个PSCCH频域资源范围，从而使得终端设备只需要在PSCCH频域资源范围内进行SCI盲检，以根据盲检结果，确定可用的PRS的传输资源，而不需要再整个PRS资源池进行SCI盲检，降低了终端设备进行SCI盲检的复杂度。
