Description

资源排除方法、装置、设备及存储介质 技术领域
本申请实施例涉及通信技术领域，尤其涉及一种资源排除方法、装置、设备及存储介质。
背景技术
在设备到设备(device to device，D2D)或车辆到其他设备(vehicle to everything，V2X)场景中，终端设备进行资源选取时，首先需要排除选择窗内的预留资源，以解决终端间的资源碰撞问题。
目前，终端设备进行资源排除操作时，若终端设备在资源侦听窗内的某些时隙上没有进行资源侦听，则该终端设备需要根据所用资源池中(预)配置的资源预留周期集合中的全部预留资源周期，将这些没有侦听时隙在资源选择窗内对应的时隙内的全部资源排除掉。
然而，在NR-V2X中，由于资源预留周期的取值比较灵活，范围更广，若终端设备依据资源预留周期集合中的全部资源预留周期进行资源排除，会导致资源选择窗内的大量资源被排除，致使可用的剩余资源不够用，进而需要提升资源块可用的信号质量阈值，从而导致终端设备无法选择到最优的可用资源。

随着网络技术及智能车辆技术的发展，车联网越来越受到广泛关注。车联网系统包括基于D2D的一种侧行链路传输技术，其与传统的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，具有更高的频谱效率以及更低的传输时延。
在第三代合作伙伴计划(3rd generation partnership project，3GPP)中，D2D分成了不同的阶段进行研究，如下：
邻近服务(proximity based services，ProSe)：主要用来提高频谱利用率和降低基站负荷。具体的，终端通过基站分配的频谱资源进行直接通信，从而提高无线频谱资源的利用率，而终端间邻近业务成功建立后，可以执行设备到设备的通信，基站的负荷得以降低，其主要针对公共安全类的业务。
车联网(V2X)：车联网系统针对车车通信的场景进行了研究，其主要面向相对高速移动的车车、车人通信的业务。
可穿戴设备(FeD2D)：主要用于可穿戴设备通过移动终端接入网络的场景，其主要面向是低移动速度以及低功率接入的场景。
下面简要介绍一下V2X通信的架构示意图。
目前，在车联网通信系统中，车联网终端通过车用无线通信技术(vehicle-to-everything，V2X)实现车与X(车、人、交通路侧基础设施和网络)智能信息的交互。V2X通信的交互模式包括：车辆与车辆(vehicle to vehicle，V2V)之间、车辆与路边基础设施(vehicle to infrastructure，V2I)之间、车辆与行人(vehicle to pedestrian，V2P)之间、车辆与网络(vehicle to network，V2N)之间的通信。示例性的，路边基础设施可以是路边单元(road side unit，RSU)。
图1为V2X通信的架构示意图。如图1所示，V2X通信包括V2V通信、V2P通信、V2I通信和V2N通信，V2X通信过程中，V2X业务通过侧行链路(sidelink)或者Uu口进行传输。
在实际应用中，V2X借助与人、车、路、云平台之间的全方位连接和高效信息交互，实现信息服务、交通安全、交通效率等典型应用场景。车联网终端通过V2I和V2N通信可以获取各种信息服务，包括交通信号灯信息，附近区域车辆信息，车辆导航，紧急救援，信息娱乐服务等。通过V2V和V2P通信可以实时获取周围车辆的车速、位置、行车情况及行人活动等信息，并通过智能算法实现碰撞预警功能，避免交通事故。通过V2I通信可以实现车速引导等功能，提高交通效率。
随着技术的不断发展，目前引入新无线(new radio，NR)通信系统，NR系统中V2X称之为NR-V2X。下面对于NR-V2X的应用场景进行解释说明。
在NR-V2X系统中，需要支持自动驾驶，因此，对车载终端之间数据交互提出了更高的要求，如更高的吞吐量、更低的时延、更高的可靠性、更大的覆盖范围、更灵活的资源分配等。
在NR-V2X系统中，通过侧行链路进行通信称之为V2X sidelink通信模式。该种通信模式下，车载终端可以工作在有网络覆盖的场景，或者没有网络覆盖的场景。
在有网络覆盖的场景中，V2X sidelink通信模式进一步的划分为集中调度传输模式和分布式传输模式。
在集中调度传输模式下，终端设备在侧行链路传输V2X业务的传输资源是由网络设备分配的，在NR-V2X系统中称为模式1，也称为mode1；在分布式传输模式下，网络设备配置V2X sidelink资源池，终端设备每次传输V2X业务时，在网络配置的资源池中获取资源，无需网络设备调度，该模式在NR-V2X系统中称为模式2，也称为mode2。详见图2和图3所示示意图的记载。
图2是模式1所适用的系统架构示意图。图3是模式2所适用的系统架构示意图。参照图2和图3所示，第一终端设备和第二终端设备是具备V2X通信能力的终端设备，用于执行V2X通信，第一终端设备与第二终端设备之间通过无线通信接口进行V2X通信，第一终端设备与网络设备，或者，第二终端设备与网络设备之间通过无线通信接口进行通信。为清楚起见，将第一终端设备和第二终端设备之间的无线通信接口称之为第一空口，该第一空口例如为sidelink，第一终端设备和网络设备之间或第二终端设备与网络设备之间的无线通信接口称之为第二空口，该第二空口例如为Uu口。
参照图2所示，作为一种示例，第一终端设备与第二终端设备的传输资源是由网络设备分配，第一终端设备与第二终端设备根据网络设备分配的资源在侧行链路上进行数据的发送；网络设备可以为第一终端设备与第二终端设备分配单次传输的资源，也可以为第一终端设备与第二终端设备分配半静态传输的资源，此处不再赘述。
参照图3所示，作为另一种示例，第一终端设备可以在资源池中选取一个资源向第二终端设备传输数据。具体的，第一终端设备可以通过侦听的方式在资源池中选取传输资源，或者通过随机选取的方式在资源池中选取传输资源，并在选择的传输资源向第二终端设备传输数据，关于第一终端设备选取传输资源的方式，其可以根据实际情况确定，此处不再赘述。
在没有网络覆盖的场景中，终端设备采用上述的模式2进行传输，这时，资源池是通过预配置的方式获取的。具体的传输方式同上述的模式2，这里不再赘述。
图4为一种通过侦听方式进行资源选取的示意图。在V2X中，当在时刻n有新的数据包到达，触发终端进行初始资源选择或触发资源重选的情况下，终端可以根据过去T0时间段(例如，T0＝1000毫秒)中的侦听结果，即在[n-T0,n]毫秒时间范围内的侦听结果，在[n+T1,n+T2]毫秒时间范围内进行资源选取，其中T1≤4；20≤T2≤100。T1的选取应该大于终端的处理时延，T2的选取需要在业务的时延要求范围内。例如，如果业务的时延要求是50ms，则20≤T2≤50，如果业务的时延要求是100ms，则20≤T2≤100。
通常，V2X场景中的终端设备可以通过在PSCCH中携带资源预留信息来指示其预留的资源，这样其他终端设备可以通过侦听的方式来确定该终端设备所预留的资源，以及自己是否需要释放预留的资源。
在LTE-V2X中，终端设备在资源选取时，可以根据其他终端设备预留的资源进行选择。假设资源选择窗内的所有可用资源作为一个资源集合A，终端对资源集合A中的资源进行排除操作的过程可以如下：
1、如果终端在侦听窗内某些子帧上发送数据，没有进行侦听，则这些子帧在选择窗内对应的子帧上的资源被排除掉。
如果终端在侦听窗内的子帧t发送了数据，导致终端在子帧t没有对其他终端的数据传输情况进行侦听。因此，该终端可以在资源选择窗内将其他终端在子帧t有可能预留的资源全部排除掉。
例如，终端所用的资源池的配置信息中包括(预)配置的资源预留周期集合M＝{100,200,300,400,500,600,700,800}ms，当终端在侦听窗内的子帧t没有进行资源侦听时，终端则可以计算t+100，t+200，t+300，t+400，t+500，t+600，t+700，t+800这些子帧是否在资源选择窗内。假设t+100，t+200，t+300，t+400，t+500这些子帧在资源选择窗内，则终端从资源集合A中排除这些子帧上全部的资源。
2、如果终端在侦听窗内检测到物理侧行控制信道(physical sidelink control channel，PSCCH)，测量该PSCCH调度的物理侧行共享信道(physical sidelink shared channel，PSSCH)的参考信号接收功率(reference signal receiving power，RSRP)。如果测量的PSSCH-RSRP高于PSSCH-RSRP门限，并且根据该PSCCH中传输的控制信息中的预留信息确定其预留的传输资源在终端的资源选择窗内，则终端在资源集合A中排除掉该资源。其中， PSSCH-RSRP门限的选取是由检测到的PSCCH中携带的优先级信息和终端待传输数据的优先级确定的。
可选地，网络设备可以向终端设备配置优先级信息与PSSCH-RSRP门限的对应关系，例如，网络设备可以向终端设备配置PSCCH中携带的优先级信息-待传输数据的优先级，与门限之间的对应关系。终端接收到该对应关系后，可以根据该对应关系，确定使用的PSSCH-RSRP门限。
通常，在待传输数据的优先级确定的情况下，检测到的PSCCH中携带的优先级越高，对应的RSRP门限越低；检测到的PSCCH中携带的优先级越低，对应的RSRP门限越高。
3、如果资源集合A中剩余的资源个数小于资源选择窗内总资源个数的20％，终端可以将PSSCH-RSRP的门限提升3dB，并且重复步骤1-2，直到资源集合A中剩余的资源个数大于总资源数的20％。
4、终端对资源集合A中剩余的资源进行侧行接收信号场强指示(sidelink received signal strength indicator，S-RSSI)检测，并且按照能量高低进行排序，把能量最低的20％(相对于资源选择窗内资源总数)资源放入集合B。
资源的S-RSSI越高，表示该资源的能量越高，终端在该资源上传输数据受到的干扰越大，则终端在选择资源时，可以尽量避免使用能量高的资源。因此，终端可以优先选择能量低的资源。
5、终端从集合B中等概率地选取一个资源进行数据传输。
在NR-V2X中，需要支持自动驾驶，因此对车辆之间数据交互提出了更高的要求，如更高的吞吐量、更低的时延、更高的可靠性、更大的覆盖范围、更灵活的资源分配等。
示例性的，图5为NR-V2X的物理层结构示意图。由图5可以看出，用于传输控制信息的PSCCH是包含在用于传输数据的PSSCH中的，这也意味着PSCCH与PSSCH必须同时发送。因此，目前标准中只支持当前传输块(transport block，TB)的初传预留当前TB的重传，当前TB的重传预留当前TB的重传，以及上一个TB的初传或重传预留当前TB的初传或重传。
示例性的，图6为一种资源预留方式的示意图。如图6所示，TB1包括资源块x1、y1和z1，TB2包括资源块x2、y2和z2。TB1的初传资源x1可以预留TB2的初传资源x2，TB2的初传资源x2可以预留TB2的重传资源y2和z2，TB2的重传资源y2可以预留TB2的重传资源z2。
在本申请的实施例中，资源预留周期是指不同TB间的资源预留间隔，例如，图6中TB1的初传预留TB2的初传，二者之间的时间间隔。资源预留周期是第一侧行控制信息中的一个域，第一侧行控制信息在PSCCH中传输。终端所用的资源池的配置信息中包括(预)配置的资源预留周期集合M，终端从资源预留周期集合M中选择一个资源预留周期放入其侧行控制信息对应的域中，从而进行TB间的资源预留。
在NR-V2X中，资源预留周期可能的取值为0，[1,99]，100，200，300，400，500，600，700，800，900，1000毫秒，资源池配置中的资源预留周期集合M由这些可能取值中的8种组成。
可以理解的是，在NR-V2X中的上述模式2下，终端也需要自行选择资源，且终端进行资源选择的机制与上述LTE-V2X中的资源选择机制类似。
示例性的，图7为NR-V2X中的一种资源选择方式的示意图。参照图7所示，终端在时刻n产生数据包，且终端需要进行资源选择。假设将资源选择窗内所有的资源作为资源集合A。资源选择窗从n+T1开始，到n+T2结束，即资源选择窗对应的时间范围为[n+T1,n+T2]。T1大于或等于终端处理数据时长以及进行资源选择所需的时长之和，T2 min≤T2≤业务的时延要求范围。T2 min的取值为{1,5,10,20}*2 μ个时隙，其中μ＝0,1,2,3对应于子载波间隔是15，30，60，120kHz的情况。
可理解，时隙为NR-V2X中的最小调度单元，子帧为LTE-V2X中的最小调度单元，因而，上述LTE-V2X中的子帧与NR-V2X中时隙是指不同通信系统中的最小调度单元。
举例说明，当子载波间隔为15kHz时，μ＝0，此时，T2 min为{1,5,10,20}个时隙中的一种，；当子载波间隔为60kHz时，此时，μ＝2，T2 min为{4,20,40,80}个时隙中的一种。
终端可以在时刻(n-T0)到时刻n之间进行资源侦听，即资源侦听窗对应的时间范围为[n-T0,n]。示例性的，T0的取值可以为100毫秒，也可以为1100毫秒，还可以是其他取值，本实施例不对T0的取值进行限定。
如果终端在资源侦听窗[n-T0,n]内的某些时隙发送数据，没有进行资源侦听，则这些时隙在资源选择窗内对应的时隙上的全部资源被排除掉。
例如，终端在时隙t没有进行资源侦听，终端所用资源池的配置中包括(预)配置的资源预留周期集合M＝{100,200,300,400,500,600,700,800}ms,则终端将计算t+100，t+200，t+300，t+400，t+500，t+600，t+700，t+800这些时隙是否在资源选择窗内，假设t+100，t+200，t+300，t+400，t+500这些时隙在资源选择窗内，则终端从资源集合A中排除这些时隙上全部的资源。
如果终端侦听到PSCCH，则终端可以测量该PSCCH的RSRP或者该PSCCH调度的PSSCH的RSRP。如果测量的RSRP大于RSRP阈值，并且根据该PSCCH中传输的控制信息中的资源预留信息确定其预留的资源在资源选择窗内，则从资源集合A中排除该PSCCH预留的资源。如果资源集合A中剩余资源不足资源集合A进行资源排除前全部资源的X％，则将RSRP阈值抬升3dB，重新进行上述资源排除步骤。其中，该RSRP阈值是由终端侦听到的PSCCH中携带的优先级和终端待发送数据的优先级决定的。
需要注意的是，NR-V2X中支持资源抢占，例如，高优先级的终端可以抢占低优先级终端的资源，以保证高优先级终端的业务优先传输。因此，终端进行资源排除后，资源集合A中可能会包含低优先级终端所预留的资源块。例如，通过调整RSRP阈值，终端可能会排除低优先级终端所预留的资源。
进行资源排除后，终端从资源集合A中的剩余资源中随机选择若干资源，作为其初次传输以及重传的发送资源。此外，终端选择的初传资源的时域位置与最后一次重传资源的时域位置相差需小于或等于一个预设值W。在NR-V2X中，W等于32个时隙。每个时隙的长度与子载波间隔有关，如果子载波间隔是15kHz，则时隙长度是1毫秒，如果子载波间隔是30kHz，则时隙长度是0.5毫秒。
有上述分析可知，无论是LTE-V2X中的资源选择机制，还是NR-V2X中的资源选择机制，如果终端1由于发送数据没有监听资源侦听窗内的某些时隙，则该终端1需要根据资源预留周期集合M中全部的资源预留周期以及没有进行侦听的时隙，把资源选择窗内对应的时隙内的全部资源排除掉。这是为了解决半双工问题，即终端1在发送数据时无法进行资源侦听导致的问题。
例如，终端1由于在时隙t发送数据而没有侦听时隙t，恰好终端2在时隙t发送了侧行控制信息，因此，终端1无法解码终端2的侧行控制信息，终端1无法排除终端2所预留的资源，若终端1选择到终端2所预留的资源，则会发生资源碰撞，降低通信可靠性。当终端1按照上述资源排除机制，依据资源池配置中包括的资源预留周期集合M中的全部资源预留周期以及未侦听的时隙进行资源排除后，即使有终端2在时隙t发送侧行控制信息，该侧行控制信息中的资源预留周期也是集合M中的一种，即终端2对应的资源会被终端1排除，从而避免了资源碰撞，提高了通信可靠性。
然而，终端1依据资源预留周期集合M中的全部资源预留周期进行资源排除，将导致资源选择窗内大量的资源被排除，若资源选择窗内的剩余资源不够，则需抬升RSRP阈值，这样将出现终端1从资源选择窗寻找次优的资源而非寻找最优的资源的情况。尤其在NR-V2X中，资源预留周期的取值更为灵活，可以取0，[1,99]一直到1000毫秒各种取值，这样使得资源预留周期集合M的实现方式多种多样，进一步加剧了资源被大量排除的问题。
针对上述问题，本申请实施例提供了一种资源排除方法，在解决半双工问题时，终端1可以只依据资源预留周期集合M中的部分资源预留周期进行资源排除，这样在解决半双工问题保证安全性的同时，可以避免资源选择窗内的大量资源块被排除，从而解决终端设备无法选择到最优可用资源的问题。
本申请实施例提供的资源排除方法可用于第三代移动通信(the 3rd generation mobile communication，3G)、长期演进(long term evolution，LTE)系统，第四代移动通信(the 4th generation mobile communication，4G)系统、先进的长期演进系统(advanced long term evolution，LTE-A)、第三代合作伙伴计划(the 3rd generation partnership project，3GPP)相关的蜂窝系统、第五代移动通信(the 5th generation mobile communication，5G)系统以及后续演进的通信系统。
本申请实施例提供的资源排除方法可用于车联网系统中，也可以用于任意的D2D系统中。
本申请实施例中涉及的网络设备，可以是普通的基站(如NodeB或eNB或者gNB)、新无线控制器(new radio controller，NR controller)、集中式网元(centralized unit)、新无线基站、射频拉远模块、微基站、中继(relay)、分布式网元(distributed unit)、接收点(transmission reception point，TRP)、传输点(transmission point，TP)或者任何其它设备，但本申请实施例不限于此。

下面，通过具体实施例对本申请的技术方案进行详细说明。需要说明的是，下面这几个具体的实施例可以相互结合，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。
图8为本申请实施例提供的资源排除方法实施例一的流程示意图。本实施例以第一终端设备为执行主体进行解释说明。如图8所示，在本实施例中，该资源排除方法可以包括如下步骤：
S801、确定资源侦听窗内的未侦听时隙。
在NR-V2X系统中，对于通过侧行链路进行通信的模式2，网络设备可以配置或预配置V2X侧行链路资源池，这样终端设备每次传输V2X业务时，便可以在网络配置的资源池中获取资源，无需网络设备调度。
在V2X场景中，终端设备可以通过在PSCCH中携带资源预留信息来指示其预留的资源，这样其他终端设备可以通过侦听的方式来确定该终端设备所预留的资源，以及自己是否需要释放预留的资源。
示例性的，在本实施例中，参照上述图7所示，假设第一终端设备在时刻n产生数据包，且需要进行资源选择，则第一终端设备的资源侦听窗对应的时间范围可以为[n-T0,n]。T0可以是协议中预定义的。示例性的，T0为100毫秒或者1100毫秒。
通常情况下，第一终端设备需要在资源侦听窗内的每个时刻均进行资源侦听，以确定出其他终端设备所预留的资源，但是，在实际应用中，第一终端设备可能会由于在资源侦听窗内的某些时隙上发送数据而没有进行资源侦听，这时为了避免资源碰撞，排除掉可能被其他终端预留的资源，需要首先确定出资源侦听窗内的未侦听时隙。
可以理解的是，资源侦听窗内的未侦听时隙可以有一个、二个或多个，本申请实施例并不对未侦听时隙的数量进行限定，其可以根据实际应用场景确定。
S802、根据该未侦听时隙和资源周期预留信息，确定资源选择窗内的需要排除的时频资源，所述资源周期预留信息是用于指示资源预留周期取值的信息。
在本实施例中，第一终端设备进行资源排除之前，首先需要获取资源池内的资源周期预留信息，确定出用于资源预留周期取值的信息，再基于上述确定的未侦听资源和用于资源预留周期取值的信息，确定出资源选择窗内的需要排除的时频资源。
示例性的，在本实施例中，参照上述图7所示，资源选择窗对应的时间范围可以为[n+T1,n+T2]，T1大于0，T2大于T1。其中，T2是根据第一终端设备中待传输数据的最大传输时延确定的，即T2的选择需要满足数据传输的时延要求。
可以理解的是，该资源周期预留信息可以是用于指示其他终端设备的资源预留周期取值的信息，也可以是用于指示该第一终端设备的资源预留周期取值的信息，还可以是同时指示使用该资源池中资源的所有终端设备的资源预留周期取值的信息。本申请实施例对其不做限定。
示例性的，在本申请的实施例中，该资源周期预留信息的确定方式为下述任意一种：
网络配置、网络预配置、终端设备确定。
可选的，在本申请的一种可能设计中，该资源周期预留信息是由网络配置的，也即，第一终端设备通过接收网络设备发送的资源周期预留信息，从而获得上述资源周期预留信息。
可选的，在本申请的另一种可能设计中，该资源周期预留信息是由网络预配置的，即第一终端设备首先接收网络设备发送的预配置信息，然后再基于该预配置信息，确定出上述资源周期预留信息。
可选的，在本申请的再一种可能设计中，该资源周期预留信息是由终端设备自己确定。例如，终端设备可以基于以往其他终端设备的资源周期预留信息，自行确定本次资源排除时需要的上述资源周期预留信息。
可理解，本申请实施例并不限定上述资源周期预留信息的具体确定方式，其可以根据实际情况选择，此处不再赘述。
在本申请的一种可能实现方式中，上述资源周期预留信息是基于第一资源预留周期集合得到的，该第一资源预留周期集合是终端设备所用的资源池支持的资源预留周期取值的集合。
在实际应用中，对于某个给定的资源池，网络设备可以首先为该资源池配置或预配置资源预留周期集合，即网络设备从NR-V2X中的资源预留周期可能的取值(0，[1,99]，100，200，300，400，500，600，700，800，900，1000毫秒)中选择8种组成资源预留周期集合，并通过配置或预配置的形式发送给使用该资源池的终端设备。
因而，在本实施例中，上述资源周期预留信息可以是基于网络配置或预配置的第一资源预留周期集合得到的，该第一资源预留周期集合是终端设备所用的资源池支持的全部资源预留周期取值的集合。
也即，该第一资源预留周期集合是资源池配置中的资源预留周期集合，其包括资源池配置中的资源预留周期集合包括的所有资源预留周期取值的集合。
在本实施例中，作为一种示例，上述资源周期预留信息为第二资源预留周期集合，该第二资源预留周期集合为第一资源预留周期集合的子集。
在本申请的实施例中，该资源周期预留信息的一种实现方式为第二资源预留周期集合，为了避免第一终端设备排除掉资源选择窗内的过多资源，该第二资源预留周期集合可以是上述网络配置或预配置的第一资源预留周期集合的子集。
可选的，第二资源预留周期集合包括第一资源预留周期集合中的至少一个资源预留周期取值。
例如，第一资源预留周期集合M＝{a，b，c，d，e，r}，这时，第二资源预留周期集合P可以为P＝{a}或者P＝{a，b，c}或者P＝{a，b，c，d}等。关于该第二资源预留周期集合包括的资源预留周期取值可以基于上述的网络配置、网络预配置、终端设备确定等多种方式中的任意一种确定，此处不再赘述。
在本实施例中，若第一终端设备由于发送数据，而没有侦听时隙t，则第一终端设备可以依据该第二资源预留周期集合中的全部资源预留周期取值以及时隙t，确定出该资源选择窗内需要排除的全部时频资源，进而在解决半双工问题的同时，避免大量的资源被排除，解决终端设备无法选择最优资源的问题。
在本实施例中，作为另一种示例，上述资源周期预留信息为目标资源预留周期取值。
可选的，该目标资源预留周期取值为第一资源预留周期集合中的任意一个资源预留周期取值。
可选的，该目标资源预留周期取值为第一资源预留周期集合中的被选中的一个资源预留周期取值。
示例性的，该目标资源预留周期取值为第一资源预留周期集合中的所有资源预留周期取值中的最小值。
在本申请的实施例中，上述资源周期预留信息可以是一个确定的资源预留周期取值，本实施例中，将其称为目标资源预留周期取值。
可选的，该目标资源预留周期取值为上述第一资源预留周期集合中的任意一个资源预留周期取值，也可以为第一资源预留周期集合中的被选中的一个资源预留周期取值，还可以是第一资源预留周期集合中的所有资源预留周期取值中的最小值。关于该目标资源预留周期取值的具体确定方法可以根据网络配置或预配置或者第一终端设备自行确定等方式中的任意一种确定。
可理解，本实施例中所述的被选中可以是网络设备选中的，也可以是第一终端设备自行确定，此处不做限定。
可选的，该目标资源预留周期取值可以是第一资源预留周期集合中的所有资源预留周期取值中的最小值，这样，终端设备基于该目标资源预留周期取值，能够排除掉资源选择窗中尽可能多的时隙对应的时频资源，从而更好的解决半双工问题。
在本实施例中，若第一终端设备在资源侦听窗内由于发送数据，而没有侦听时隙t，则第一终端设备可以依据目标资源预留周期以及时隙t，确定出在资源选择窗内需要排除的全部时频资源，从而解决半双工问题。
进一步的，在本申请的实施例中，参照图8所示，该方法还可以包括如下步骤：
S803、从该资源选择窗内排除上述需要排除的时频资源。
在本实施例中，当第一终端设备确定出资源选择窗内的需要排除的时频资源时，终端设备便可以将其从资源选择窗对应的资源中排除掉上述需要排除的时频资源，以解决终端设备之间的半双工问题。
本申请实施例提供的资源排除方法，通过确定资源侦听窗内的未侦听时隙，根据该未侦听时隙和资源周期预留信息，确定资源选择窗内的需要排除的时频资源，该资源周期预留信息是用于指示资源预留周期取值的信息，进而从该资源选择窗内排除上述需要排除的时频资源。该技术方案中，第一终端设备可以只依据用于指示资源预留周期取值的信息和未侦听时隙进行资源排除，在解决半双工问题保证安全性的同时，避免了资源选择窗内的大量资源块被排除，从而解决了终端设备无法选择到最优可用资源的问题。
示例性的，在上述实施例的基础上，图9为本申请实施例提供的资源排除方法实施例二的流程示意图。如图9所示，在本实施例中，上述S802可以通过如下步骤实现：
S901、确定该资源周期预留信息对应的所有资源预留周期取值。
在本实施例中，第一终端设备获取到资源周期预留信息时，确定出其对应的所有资源预留周期取值。
例如，当该资源周期预留信息为一个资源预留周期集合时，例如，资源预留周期集合P＝{a,b,c}，这时确定出该资源预留周期集合包括的所有资源预留周期取值的具体数值，即，资源预留周期集合P＝{a,b,c}中a,b,c的具体取值。
再比如，当该资源周期预留信息为一个资源预留周期取值时，例如，资源预留周期取值r，则确定出该资源预留周期取值r的具体数值。
S902、根据未侦听时隙和上述资源周期预留信息对应的所有资源预留周期取值，确定需要排除的所有时隙。
在本实施例中，第一终端设备可以在确定出未侦听时隙和资源周期预留信息对应的所有资源预留周期取值后，可以通过将未侦听时隙与所有资源预留周期取值相加或将未侦听时隙与所有资源预留周期取值的倍数相加，确定出对应的时隙，即需要排除的所有时隙。
例如，假设资源侦听窗内的未侦听时隙为t，资源周期预留信息对应的所有资源预留周期取值有a,b,c，则需要排除的所有时隙可以有t+a、t+b、t+c、…、t+na、t+nb、t+nc等，其中，n为正整数。
S903、根据该资源选择窗和上述需要排除的所有时隙，确定该资源选择窗内的需要排除的时频资源。
在本实施例中，第一终端设备根据资源选择窗对应的时间范围，在S902确定的需要排除的所有时隙中，确定出位于该资源选择窗内的时隙，最后将位于该资源选择窗内的时隙对应的全部时频资源确定为该资源选择窗内的需要排除的时频资源。
例如，S902中确定的需要排除的所有时隙t+a、t+b、t+c、…、t+na、t+nb、t+nc中，只有t+a、t+b、t+c和t+2a等时隙位于资源选择窗内，则将t+a、t+b、t+c和t+2a等时隙的全部时频资源确定为资源选择窗内的需要排除的时频资源。
本申请实施例提供的资源排除方法，通过确定该资源周期预留信息对应的所有资源预留周期取值，再根据未侦听时隙和资源周期预留信息对应的所有资源预留周期取值，确定需要排除的所有时隙，最后根据该资源选择窗和上述需要排除的所有时隙，确定该资源选择窗内的需要排除的时频资源。该技术方案能够准确确定出资源选择窗内的需要排除的时频资源，为后续资源的准确排除奠定了基础。
上面对本申请的技术方案进行了详细的介绍。下面通过具体例子进行进一步说明。
示例性，图10为本申请实施例提供的一种资源排除方式的示意图。如图10所示，资源侦听窗对应的时间范围为[n-T0,n]，在n时刻有数据到达，资源选择窗对应的时间范围为[n+T1,n+T2]。即，第一终端设备依据n-T0到n时刻资源侦听窗内的侦听结果，排除资源选择窗n+T1到n+T2内对应的时频资源。
具体的，第一终端设备所用资源池的配置中包括：由网络配置或预配置的资源预留周期集合M＝{a，b，c，d，e}。资源预留周期集合P＝{a,b,c}是资源预留周期集合M的子集。资源预留周期集合P由网络配置或预配置或第一终端设备自行选择。
如图10所示，第一终端设备在时隙t由于发送数据而没有进行资源侦听，则第一终端设备根据资源预留周期集合P中的全部资源预留周期{a,b,c}以及时隙t，将选择窗内时隙{t+a，t+2a，t+b，t+c}内全部的时频资源排除，解决了半双工问题，并且避免资源选择窗内大量的资源块被排除，解决了终端设备无法选择到最优可用资源的问题。
示例性，图11为本申请实施例提供的另一种资源排除方式的示意图。如图11所示，资源侦听窗和资源选择窗的范围均与图10所示示意图中的一样，即，在n时刻有数据到达时，第一终端设备依据n-T0到n时刻资源侦听窗内的侦听结果，排除资源选择窗n+T1到n+T2内对应的时频资源。
可选的，第一终端设备所用资源池的配置中包括：由网络配置或预配置的资源预留周期集合M＝{a，b，c，d，e，r}。资源预留周期r是资源预留周期集合M中的一个资源预留周期，该资源预留周期r可以由网络配置或预配置或第一终端设备自行选择。可选的，资源预留周期r为资源预留周期集合M中的最小值。
如图11所示，第一终端设备在时隙t发送数据没有进行资源侦听，则第一终端设备根据资源预留周期r以及时隙t，将选择窗内时隙{t+r，t+2r}内全部的时频资源排除，解决了半双工问题，并且避免资源选择窗内大量的资源块被排除，解决了终端设备无法选择到最优可用资源的问题。
上述介绍了本申请实施例提到的资源排除方法的具体实现，下述为本申请装置实施例，可以用于执行本申请方法实施例。对于本申请装置实施例中未披露的细节，请参照本申请方法实施例。
图12为本申请实施例提供的资源排除装置实施例一的结构示意图。该装置可以集成在终端设备中，也可以通过终端设备实现。如图12所示，该装置可以包括：第一处理单元1201和第二处理单元1202。
其中，该第一处理单元1201，用于确定资源侦听窗内的未侦听时隙；
该第二处理单元1202，用于根据所述未侦听时隙和资源周期预留信息，确定资源选择窗内的需要排除的时频资源，所述资源周期预留信息是用于指示资源预留周期取值的信息。
在本申请的一种可能设计中，述资源周期预留信息是基于第一资源预留周期集合得到的，所述第一资源预留周期集合是终端设备所用的资源池支持的资源预留周期取值的集合。
作为一种示例，所述资源周期预留信息为第二资源预留周期集合，所述第二资源预留周期集合为所述第一资源预留周期集合的子集。
