Description

一种数据传输的方法、装置以及系统 技术领域
本申请实施例涉及通信领域，尤其涉及一种数据传输的方法、装置以及系统。
背景技术
随着无线通信技术的发展，人们对高数据速率和用户体验的需求日益增长，因此人们对了解周边人或事物，并与周边人或事物通信的邻近服务的需求逐渐增加，从而设备到设备(device-to-device，D2D)技术应运而生，D2D技术允许多个支持D2D功能的用户设备(user equipment，UE)在有网络基础设施或无网络基础设施的情况下进行直接发现和直接通信。在第三代合作伙伴计划(the 3rd generation partnership project，3GPP)提出的长期演进(long term evolution，LTE)技术的网络下，进一步提出车与任何事物通信(vehicle-to-everything，V2X)的车联网技术。在V2X场景中的用户资源自选模式下，资源池配置信息包括至少2种类型的资源池，一种是UE基于侦听(sensing)进行资源选择用于数据传输的资源池类型，另一种是UE基于部分侦听选择(partial-sensing)进行资源选择用于数据传输的资源池类型，或随机选择资源用于数据传输的资源池类型，由于其中随机选择的UE根据侦听结果来进行资源排除，会提升随机选择的资源和其他用户选择的资源碰撞的概率。
目前，为了降低资源碰撞概率，可以将基于侦听进行资源选择以及基于部分侦听选择进行资源选择的不同类型的资源池进行单独配置，且资源池的时频资源不完全重合，因此可以减少进行不同资源选择的UE之间的干扰，即基于侦听选择资源的UE和随机选择资源的UE处于不同资源池进行资源选择。
然而，由于每个数据的服务质量(Quality of Service，QoS)不同，因此每次传输的物理层侧行链路共享信道(Physical Sidelink Shared Channel，PSSCH)的优先级也不同，而处于不同资源池进行资源选择，在随机选择资源的传输方式中，高优先级的PSSCH和低优先级的PSSCH发生碰撞的概率类似，因此同时进行资源选择时，可能出现高优先级的PSSCH和低优先级的PSSCH发生碰撞，因此无法保证高优先级PSSCH的QoS需求，从而降低对高优先级PSSCH的QoS。
发明内容
本申请实施例提供了一种数据传输的方法、装置以及设备。用于降低高优先级的PSSCH和低优先级的PSSCH发生碰撞的概率，由此能够保证优先级较高的PSSCH的QoS，从而提升高优先级PSSCH的QoS。
第一方面，本申请提供了一种数据传输的方法。包括：首先获取包括第一资源池信息和第二资源池信息的资源池配置信息，该资源池配置信息可以是基于侧行带宽部分(sidelink bandwidth part，SL-BWP)配置得到的，且第一资源池信息用于指示第一资源池，第二资源池信息用于指示第二资源池，且第一资源池的资源确定方式包括全侦听选择的资源确定方式，第二资源池的资源确定方式包括部分侦听选择的资源确定方式以及随机选择的资源确定方式中至少一种。应理解，在实际应用中，第一资源池的资源确定方式还可以包括部分侦听选择和/或随机选择，第二资源池只能用于部分侦听选择和/或随机选择， 具体此处不做限定。然后，获取物理层侧行链路共享信道PSSCH所对应的第一优先级值，第一优先级值为PSSCH本身所对应的优先级，第一优先级可以在相对应的SCI中指示。应理解，第一优先级值可以为PSSCH上承载的数据所对应的优先级，或者第一优先级值还可以为PSSCH上承载的数据业务所对应的优先级。在第一优先级值小于第一优先级阈值时，确定在第一资源池以部分侦听选择资源确定方式和/或随机选择资源确定方式确定发送PSSCH的资源，而第一优先级值大于或等于第一优先级阈值时，确定在第二资源池部分侦听选择资源确定方式和/或随机选择资源确定方式确定发送PSSCH的资源。
在该实施方式中，由于优先级值越小指示优先级越高，在第一优先级值小于第一优先级阈值时，高优先级的PSSCH可以确定在第一资源池以部分侦听选择资源确定方式和/或随机选择资源确定方式确定发送PSSCH的资源，能够降低高优先级的PSSCH和低优先级的PSSCH发生碰撞的概率，由此保证优先级较高的PSSCH的QoS，从而提升对高优先级PSSCH的QoS。
结合本申请实施例的第一方面，在本申请实施例的第一方面的第一种实施方式中，第一资源池信息还用于指示随机选择配置信息，随机选择配置信息包括使能(enabled)随机选择的资源确定方式，或，禁止使能(disabled)随机选择的资源确定方式。因此，确定第一优先级值小于第一优先级阈值，还需要确定第一资源池信息是否指示使能随机选择的资源确定方式，因此第一资源池信息指示使能随机选择的资源确定方式时，可以确定在第一资源池中以随机选择的资源确定方式确定发送PSSCH的资源，而第一资源池信息指示禁止使能随机选择的资源确定方式时，那么即确定在第二资源池中以随机选择的资源确定方式确定发送PSSCH的资源。其次，第一资源池信息指示禁止使能随机选择的资源确定方式，由于第一资源池禁止使能随机选择，此时确定在第二资源池中以随机选择的资源确定方式确定发送PSSCH的资源。
在该实施方式中，通过随机选择配置信息确定第一资源池信息能否进行随机选择的资源确定方式，高优先级的PSSCH可以在第一资源池使能随机选择的资源确定方式时，能够在第一资源池中以随机选择的资源确定方式确定发送高优先级的PSSCH所对应的资源，进一步地提升对高优先级PSSCH的QoS。其次，而在禁止随机选择的资源确定方式时，在第二资源池中以随机选择的资源确定方式确定发送PSSCH的资源，能够保证资源能够顺利发送，且限定了在资源池中具体以随机选择的资源确定方式发送PSSCH的资源，从而提升本方案的可实现性。
结合本申请实施例的第一方面，在本申请实施例的第一方面的第二种实施方式中，第一资源池信息还用于指示抢占信息，抢占信息包括使能抢占(pre-emption)的资源确定方式，或，禁止使能抢占的资源确定方式。因此，在第一资源池信息指示使能抢占的资源确定方式时，还需要确定第一优先级值是否小于第一优先级阈值，在第一优先级值小于第一优先级阈值时，可以确定在第一资源池中以随机选择的资源确定方式确定发送PSSCH的资源，而第一优先级值大于或等于第一优先级阈值时，即确定在第二资源池中以随机选择的资源确定方式确定发送PSSCH的资源。其次，第一资源池信息指示禁止使能抢占的资源确定方式，那么即允许在第一资源池进行使能抢占，此时不考虑第一优先级值，即确定在第二资源池中以随机选择的资源确定方式确定发送PSSCH的资源。
在该实施方式中，将随机选择的资源确定方式的触发条件与抢占的的资源确定方式的触发条件进行关联关系，在第一资源池允许抢占时，第一优先级数值要小于第一优先级阈值才能够进行随机选择，提升在第一资源池中以随机选择的资源确定方式确定发送PSSCH的资源的条件要求，限制以随机选择的资源确定方式确定发送PSSCH的数量，提升了以随机选择的资源确定方式发送高优先级PSSCH中资源的可靠性，从而进一步地提升高优先级PSSCH的QoS。
结合本申请实施例的第一方面，在本申请实施例的第一方面的第三种实施方式中，第一资源池信息还用于指示抢占信息，抢占信息包括使能抢占(pre-emption)的资源确定方式，或，禁止使能抢占的资源确定方式。在该实施方式中，第一资源池信息指示禁止使能抢占的资源确定方式时，即禁止在第一资源池进行使能抢占时，才需要进一步地确定第一优先级值是否小于第一优先级阈值，因此在第一优先级值小于第一优先级阈值时，可以确定在第一资源池中以随机选择的资源确定方式确定发送PSSCH的资源，而第一优先级值大于或等于第一优先级阈值时，即确定在第二资源池中以随机选择的资源确定方式确定发送PSSCH的资源。其次，第一资源池信息指示使能抢占的资源确定方式，那么即允许在第一资源池进行使能抢占时，无法在第一资源池中以随机选择的资源确定方式确定发送PSSCH的资源，此时不考虑第一优先级值，即确定在第二资源池中以随机选择的资源确定方式确定发送PSSCH的资源。
在该实施方式中，由于随机选择的资源确定方式对全侦听选择的资源确定方式而言会造成性能影响，抢占也可能也会对全侦听选择的资源确定方式造成影响，因此第一资源池信息指示禁止使能抢占的资源确定方式，且第一优先级值小于第一优先级阈值，可以确定在第一资源池中以随机选择的资源确定方式确定发送高优先级的PSSCH所对应的资源，而其他情况下均在第二资源池中以随机选择的资源确定方式确定发送PSSCH的资源，由此可以降低随机选择以及抢占之间的干扰和冲突影响，从而降低对随机选择的资源确定方式发送高优先级PSSCH的碰撞，进而能够保证优先级较高的PSSCH的QoS。
结合本申请实施例的第一方面，在本申请实施例的第一方面的第四种实施方式中，第一资源池信息还用于指示部分侦听选择配置信息，部分侦听选择配置信息包括使能部分侦听选择的资源确定方式，或，禁止使能部分侦听选择的资源确定方式。与本申请实施例的第一方面的第一种实施方式类似，在确定第一优先级值小于第一优先级阈值后，还需要确定第一资源池信息是否指示使能部分侦听选择的资源确定方式，因此第一资源池信息指示使能部分侦听选择的资源确定方式时，可以确定在第一资源池中以部分侦听选择的资源确定方式确定发送PSSCH的资源，而第一资源池信息指示禁止使能部分侦听选择的资源确定方式时，那么即确定在第二资源池中以部分侦听选择的资源确定方式确定发送PSSCH的资源。其次，第一资源池信息指示禁止使能部分侦听选择的资源确定方式，由于第一资源池禁止使能部分侦听选择，此时确定在第二资源池中以部分侦听选择的资源确定方式确定发送PSSCH的资源。
在该实施方式中，通过部分侦听选择配置信息确定第一资源池信息能否进行部分侦听选择的资源确定方式，高优先级的PSSCH可以在第一资源池使能部分侦听选择的资源确定方式时，能够在第一资源池中以部分侦听选择的资源确定方式确定发送高优先级的PSSCH 所对应的资源，进一步地提升对高优先级PSSCH的QoS。其次，而在禁止部分侦听选择的资源确定方式时，在第二资源池中以部分侦听选择的资源确定方式确定发送PSSCH的资源，能够保证资源能够顺利发送，且限定了在资源池中具体以部分侦听选择的资源确定方式发送PSSCH的资源，从而提升本方案的可实现性。
结合本申请实施例的第一方面，在本申请实施例的第一方面的第五种实施方式中，第一资源池信息还用于指示抢占信息，抢占信息包括使能抢占的资源确定方式，或，禁止使能抢占的资源确定方式。与本申请实施例的第一方面的第二种实施方式类似，在第一资源池信息指示使能抢占的资源确定方式时，还需要确定第一优先级值是否小于第一优先级阈值，在第一优先级值小于第一优先级阈值时，可以确定在第一资源池中以部分侦听选择的资源确定方式确定发送PSSCH的资源，而第一优先级值大于或等于第一优先级阈值时，即确定在第二资源池中以部分侦听选择的资源确定方式确定发送PSSCH的资源。其次，第一资源池信息指示禁止使能抢占的资源确定方式，此时不考虑第一优先级值，即确定在第二资源池中以部分侦听选择的资源确定方式确定发送PSSCH的资源。
在该实施方式中，将部分侦听选择的资源确定方式的触发条件与抢占的的资源确定方式的触发条件进行关联关系，在第一资源池允许抢占时，第一优先级数值要小于第一优先级阈值才能够进行部分侦听选择，提升在第一资源池中以部分侦听选择的资源确定方式确定发送PSSCH的资源的条件要求，限制以部分侦听选择的资源确定方式确定发送PSSCH的数量，提升了以部分侦听选择的资源确定方式发送高优先级PSSCH中资源的可靠性，从而进一步地提升高优先级PSSCH的QoS。
结合本申请实施例的第一方面，在本申请实施例的第一方面的第六种实施方式中，第一资源池信息还用于指示抢占信息，抢占信息包括使能抢占的资源确定方式，或，禁止使能抢占的资源确定方式。与本申请实施例的第一方面的第三种实施方式类似，在该实施方式中，第一资源池信息指示禁止使能抢占的资源确定方式时，即禁止在第一资源池进行使能抢占时，才需要进一步地确定第一优先级值是否小于第一优先级阈值，因此在第一优先级值小于第一优先级阈值时，可以确定在第一资源池中以部分侦听选择的资源确定方式确定发送PSSCH的资源，而第一优先级值大于或等于第一优先级阈值时，即确定在第二资源池中以部分侦听选择的资源确定方式确定发送PSSCH的资源。其次，第一资源池信息指示使能抢占的资源确定方式，此时不考虑第一优先级值，即确定在第二资源池中以部分侦听选择的资源确定方式确定发送PSSCH的资源。
在该实施方式中，由于部分侦听选择的资源确定方式对全侦听选择的资源确定方式而言会造成性能影响，抢占也可能也会对全侦听选择的资源确定方式造成影响，因此第一资源池信息指示禁止使能抢占的资源确定方式，且第一优先级值小于第一优先级阈值，可以确定在第一资源池中以部分侦听选择的资源确定方式确定发送高优先级的PSSCH所对应的资源，而其他情况下均在第二资源池中以部分侦听选择的资源确定方式确定发送PSSCH的资源，由此可以降低部分侦听选择以及抢占之间的干扰和冲突影响，从而降低对部分侦听选择的资源确定方式发送高优先级PSSCH的碰撞，进而能够保证优先级较高的PSSCH的QoS。
结合本申请实施例的第一方面至本申请实施例的第一方面的第六种实施方式中的任意一种，本申请实施例的第一方面的第七种实施方式中，在PSSCH所对应的发送功率小于或 等于发送功率阈值时，执行确定在第一资源池以部分侦听选择资源确定方式和/或随机选择资源确定方式确定发送PSSCH的资源的步骤。
在该实施方式中，具体限定执行确定在第一资源池以部分侦听选择资源确定方式和/或随机选择资源确定方式确定发送PSSCH的资源的步骤的一种条件，在满足PSSCH所对应的发送功率小于或等于发送功率阈值的条件时才会在第一资源池发送PSSCH，由此提升本方案的可实现性。
结合本申请实施例的第一方面至本申请实施例的第一方面的第六种实施方式中的任意一种，本申请实施例的第一方面的第八种实施方式中，终端装置的电池余量小于或等于电量阈值时，执行确定在第一资源池以部分侦听选择资源确定方式和/或随机选择资源确定方式确定发送PSSCH的资源的步骤。

具体实施方式
下面结合附图并举实施例，对本申请提供的技术方案作进一步说明。应理解，本申请实施例中提供的系统结构和业务场景主要是为了说明本申请的技术方案的可能的实施方式，不应被解读为对本申请的技术方案的唯一限定。本领域普通技术人员可知，随着系统结构的演进和新业务场景的出现，本申请提供的技术方案对类似技术问题同样适用。
本申请的说明书和权利要求书及上述附图中的术语“第一”、“第二”、“第三”、“第四”等(如果存在)是用于区别类似的对象，而不必用于描述特定的顺序或先后次序。应该理解这样使用的数据在适当情况下可以互换，以便这里描述的实施例能够以除了在这里图示或描述的内容以外的顺序实施。另外，术语“包括”和“具有”以及他们的任何变形，意图在于覆盖不排他的包含，例如，包含了一系列步骤或单元的过程、方法、系统、产品或设备不必限于清楚地列出的那些步骤或单元，而是可包括没有清楚地列出的或对于这些过 程、方法、产品或设备固有的其它步骤或单元。
为了更好地理解本申请实施例公开的一种数据传输的方法、装置以及设备，首先，对本发明实施例所使用的通信系统的系统架构进行描述。本发明应用在D2D、V2X等终端装置和终端装置直接通信的系统中，且在该通信系统中允许多个终端装置在有网络基础设施或无网络基础设施的情况下进行直接发现和直接通信，因此本申请实施例公开的方法适用于有网络覆盖和无网络覆盖的通信场景，具体地，请参阅图1，图1为本申请实施例中系统框架的一个示意图，如图所示，图1中(A)图示出的为，终端装置均处于有网络覆盖的通信场景下，终端装置与终端装置之间进行直接通信，而终端装置与网络装置之间通过演进的通用陆地无线接入网络(evolved universal terrestrial radio access network，UTRAN)与用户设备进行通信。其次，图1中(B)图示出的为，终端装置并未均处于有网络覆盖的通信场景下，终端装置与终端装置之间通过PCS进行通信，而处于处于有网络覆盖的终端装置与网络装置通过UTRAN与用户设备(UTRAN-to-UE，Uu)进行通信。再次，图1中(C)图示出的为，终端装置均处于无网络覆盖的通信场景下，终端装置与终端装置之间通过PCS进行通信。
进一步地，车联网应用场景被提出，但是因涉及安全性的考虑，这种场景下对时延的要求非常高。因此，在3GPP提出的LTE技术的网络下，V2X的车联网技术被提出，V2X通信是指车辆与外界的任何事物的通信。具体地，请参阅图2，图2为本申请实施例中V2X通信的一个示意图，如图所示，V2X通信包括但不限于车与车的通信(vehicle to vehicle，V2V)、车与行人的通信(vehicle to pedestrian，V2P)车与网络的通信(vehicle to network，V2N)，具体V2X通信还可以包括车与基础设施的通信(vehicle to infrastructure，V2I)等，在此不对V2X通信进行穷举。其次，V2X通信针对以车辆为代表的高速设备，可以应用于如智能汽车、自动驾驶、智能交通运输系统等场景。由于V2X通信可以支持有网络覆盖和无网络覆盖的通信场景，因此V2X通信的资源分配方式可以采取网络接入设备调度模式，示例性地，如演进通用陆地无线接入网节点B(E-UTRAN Node B，eNB)调度模式和UE自选模式，基于V2X技术，车辆用户(vehicle UE，V-UE)可以将自身的一些信息，例如位置、速度、意图(例如转弯、并线、倒车)等信息周期性以及一些非周期性的事件触发的信息向周围的V-UE发送，同样地V-UE也会实时接收周围用户的信息。
其次，考虑演进的通用陆地无线接入网络与用户设备(UTRAN-to-UE，Uu)空口传输，无线通信的双方可以包括网络装置和终端装置。其次，考虑侧行链路(sidelink，SL)空口传输，那么无线通信的收发端均为终端装置。因此，网络装置在LTE无线通信系统以及传统通用移动通信系统(universal mobile telecommunications System，UMTS)中可以是传统宏基站eNB(evolved node B)，在异构网络(heterogeneous network，HetNet)场景下可以是微基站eNB，在分布式基站场景可以是基带处理单元(base band unit，BBU)和射频拉远单元(remote radio unit，RRU)，在云无线接入网(cloud radio access netowrk，CRAN)场景下可以是基带池(pool)和射频单元，在未来无线通信系统，例如，第五代移动通信技术(5th generation mobile networks，5G)新空口(new radio，NR)系统，或者是基站(gNB)。而终端装置可以是车载通信模块或其它嵌入式通信模块，也可以是用户手持通信设备，包括手机，平板电脑等，具体此处不做限定。
其次，对本申请实施例涉及到的一些术语或概念进行解释，以便于本领域技术人员理解。
一、全侦听的资源确定方式。
基于侦听(sensing)进行资源选择用于数据传输的方式，以侦听的时间单元的多少分类，可以分为全侦听(full sensing)以及部分侦听选择(partial sensing)。其中，全侦听是在侦听窗[n-T 0,n-T prco,0]所包括的所有时间单元进行侦听，应理解，用于发送的时间单元可以不侦听。
具体地，基于侦听进行资源确定的包括如下过程。
首先，第一终端装置在slot n时刻产生待发送的PSSCH，UE在侦听窗[n-T 0,n-T prco,0]内的资源池内接收来自第二终端装置的PSCCH，或者接收来自第二终端装置的PSCCH以及PSSCH。具体地，在PSCCH检测和解码SCI。其中，一个SCI可以调度至少一次传输，示例性地，一个SCI调度3次传输，那么这3次传输中第一次传输是一个PSSCH所承载的数据的初次传输，后两次传输则该PSSCH所承载的数据的重传，或者还可以说这3次传输都是某一个数据的重传。SCI包括的侦听信息包含第二次和第三次的数据的重传的时频资源信息、体现数据业务周期的周期性时频资源信息以及数据优先级信息(priority of PSSCH)等。可以理解的是，在给定的一个时刻，第一终端装置通过发送一个SCI来预约在该时刻之后的一个时频资源用于一个数据的新传或重传，然后第二终端装置通过译码SCI来获知这个用户的时频资源预约情况，从而避免选择被预约的时频资源以降低资源碰撞。其中，第一终端装置与第二终端装置为不同的终端装置，第二终端装置可以为不同于第一终端装置的至少一个终端装置。
进一步地，如果第一终端装置从第二终端装置的SCI的侦听信息中得知，第二终端装置预约的时频资源位于第一终端装置的资源选择窗[n+T 1,n+T 2]内，那么第一终端装置可以根据该侦听信息，对第二终端装置需要在该时频资源上发送的数据或控制信道的解调参考信号(demodulation reference signal，DMRS)进行测量，得到参考信号接收功率(reference signal received power，RSRP)，其中，T 1用于指示，T 2用于指示。如果该RSRP大于门限阈值Th RSRP，则该UE从资源选择窗中排除该时频资源。该UE在排除资源选择窗内的不可用的时频资源后，可以确定资源选择窗内剩余的时频资源为可用的时频资源，从而在可用的时频资源中选择时频资源以发送数据。其中，门限阈值可以为预先设定的，或者接入网设备配置的，或者预配置的。
最后，第一终端装置在排除资源选择窗内的不可用的时频资源后，可以确定资源选择窗内剩余的时频资源为可用的时频资源，从而在可用的时频资源中选择时频资源以发送数据。
由此可知，第一终端装置发送数据时所使用的时频资源，是基于第一终端装置基于侦听窗[n-T 0,n-T prco,0]内的侦听结果(即确定的可用的资源)来选择的。
具体地，本申请实施例中，侦听结果是指通过前述步骤来确定的结果，T 0以及T prco,0用于确定侦听窗的大小，T 0以及T prco,0为大于或等于0，且以一个时间单位为单位的时域值， 例如T 0可以取值为1100ms对应的子载波间隔(sub-carrier spacing，SCS)所确定的slot个数，或者100ms对应的SCS所确定的slot个数。而T prco,0可以根据不同SCS，取值为正整数，例如1,2，3或4，T prco,0具体取值可以根据用户终端的硬件处理侦听结果的能力来确定。其次，T 1以及T 2用于确定选择窗的大小，T 1以及T 2为大于或等于0，且以一个时间单位为单位的时域值，T 1以及T 2具体取值可以根据终端装置自身的处理时延的能力和待发送数据的QoS需求有关。
二、部分侦听选择的资源确定方式。
部分侦听选择的资源确定方式即为基于部分侦听选择(partial-sensing)进行资源选择用于数据传输用于数据传输的方式，应理解，部分侦听选择是在一段时间内(例如1100ms内，或100ms内，或一段时间即等于全侦听的侦听窗)的若干个时间单元上进行侦听，其余步骤与前述全侦听的方式类似，在此不再赘述赘述。
可以理解的是，本申请实施例中若未特别说明为哪种侦听方式，所描述的侦听的资源确定方式表示为全侦听的资源确定方式，也可以理解为全侦听的资源确定方式与侦听资源确定方式相互替换，但不论是全侦听还是部分侦听选择，都是基于侦听结果来在资源选择窗(selection window)中选择资源用于发送PSSCH。
三、随机选择的资源确定方式。
随机选择的资源确定方式为不需要基于侦听进行资源确定，直接在资源选择窗中随机选择资源发送PSSCH中的资源。
可以理解的是，本申请实施例中所描述的高优先级终端装置，高优先级PSSCH以及高优先级数据，均指在一个时间单元终端装置所发送或接收的PSSCH的优先级。具体地，优先级在调度PSSCH对应的SCI中指示，即高优先级指示PSSCH的优先级(Priority)高，而优先级越高，PSSCH所承载的数据的QoS需求越高。本实施例中以优先级值(Priority Value)表示优先级，定义优先级越高所对应的优先级值越低，优先级越低所对应的优先级值越高。在实际应用中，还可以为优先级越高所对应的优先级值越高，而优先级越低所对应的优先级值越低，本实施例中的示例仅用于理解本方案，不应理解为本申请的限定。
通过前述介绍可知，进行随机选择的终端装置由于没有根据侦听结果来进行资源排除，会导致随机选择的资源和其他用户选择的资源碰撞的概率增大，为了降低资源碰撞概率，可以将两种不同类型的资源池进行单独配置，且资源池的时频资源不完全重合，因此可以减少进行不同资源选择的UE之间的干扰，即基于侦听选择资源的UE和随机选择资源的UE处于不同资源池进行资源选择。由于每个数据的QoS不同，因此每次传输的PSSCH的优先级也不同，而处于不同资源池进行资源选择，在随机选择资源的传输方式中，高优先级的PSSCH和低优先级的PSSCH发生碰撞的概率类似，因此同时进行资源选择时，可能出现高优先级的PSSCH和低优先级的PSSCH发生碰撞，因此无法保证高优先级PSSCH的QoS需求，从而降低对高优先级PSSCH的QoS。
为了解决上述问题，本申请实施例提供了一种数据传输的方法，用于降低高优先级的 PSSCH和低优先级的PSSCH发生碰撞的概率，由此能够保证优先级较高的PSSCH的QoS，从而提升对高优先级PSSCH的QoS。
下面将以第一终端装置为执行主体对本申请实施例使用的数据传输的方法进行详细描述，请参阅图3，图3为本申请实施例中数据传输的方法一个实施例的示意图，数据传输的方法包括如下步骤。
S101、终端装置获取资源池配置信息。
本实施例中，需要先获取资源池配置信息，该资源池配置信息为第一终端装置获取的，具体为第一终端装置接收网络装置所发送的资源池配置信息，资源池配置信息还可以是基于侧行带宽部分(sidelink bandwidth part，SL-BWP)配置得到的。其中，资源池配置信息包括第一资源池信息以及第二资源池信息，第一资源池信息用于指示第一资源池，而第二资源池信息用于指示第二资源池，第一资源池与第二资源池为不同类型的资源池，第一资源池为第一时频资源的集合，而第二资源池为第二时频资源的集合，第一资源池的资源确定方式包括全侦听，而第二资源池的资源确定方式包括部分侦听选择以及随机选择的至少一种。应理解，在实际应用中，第一资源池的资源确定方式还可以包括部分侦听选择和/或随机选择，第二资源池只能用于部分侦听选择和/或随机选择，具体此处不做限定。
具体地，在网络覆盖范围下，第一终端装置可以基于接收网络装置通过系统消息块(system information block，SIB)获取资源池配置信息，或，基于接收网络装置通过小区级(cell-specific)的无线资源控制(radio resource control，RRC)信令获取资源池配置信息，或，基于接收网络装置通过终端用户级(UE-specific)RRC信令获取资源池配置信息。而没有网络覆盖范围时，第一终端装置可以使用设备出厂预配置的侧行链路(Sidelink，SL)资源池(Resource Pool)的配置信息作为资源池配置信息。前述资源池配置信息具体即为SL资源池的配置信息。
进一步地，资源池配置信息还用于终端装置之间进行侧行通信，包括终端装置发送和接收多种信道，例如用于侧行通信的物理层信道，包括但不限于物理层侧行链路控制信道(physical sidelink control channel，PSCCH)，PSSCH，物理层侧行链路发现信道(physical sidelink discovery channel，PSDCH)，物理层侧行广播信道(physical sidelink broadcast channel，PSBCH)以及物理层侧行链路反馈信道(physical sidelink feedback channel，PSFCH)中至少一种信道。其中，PSSCH所承载的业务类型可以包括单播通信类型、组播通信类型或广播通信类型中任一类型。
示例性地，在SL资源池的时域上，可以包括一个或多个时间单元，时间单元可以包括但不限于为一个符号(symbol)、若干个符号、一个时隙(slot)、一个子帧以及一个帧等，一个或多个时间单元可以在时间上为连续的，也可以在时间上为离散的。其次，在SL资源池的频域上，可以包括一个或多个频域单元，而频域单元可以包括但不限于为一个资源元素(resource element，RE)、若干个RE、一个资源块(resource block，RB)、若干个RB、一个子信道(sub channel)以及若干个子信道等，其中，一个子信道包括一个或多个在频域上连续的RB，或，非连续的RB。为了便于理解，本实施例中，时间单元以时隙进行描述，而时频域单元以子信道进行描述，可以理解的是，在实际应用中，时间单元还可以包括但不限于为前述实施例所介绍的符号以及子帧等，而时频域单元还可以包括但不限于为前述 实施例所介绍的资源块以及资源元素等，具体时间单元以及时频域单元需要通过实际需求以及应用灵活确定，此处不做限定。
可选地，第一终端装置所获得的资源池配置信息还可以用于指示N个发送资源池(TxPool)以及P个接收资源池(RxPool)，由于发送资源池用于发送SL，而接收资源池用于接收SL，因此所配置的接收资源池的总数量大于或等于配置的发送资源池的总数量，即P大于或等于N。由此可以保证第一终端装置可以尽可能地收到来自不同发送资源池发送的数据。示例性地，发送资源池可以包括但不限于用于根据网络调度而进行侧行通信的发送资源池(TxPoolScheduling)、用于根据自主资源选择而进行侧行通信的发送资源池(TxPoolSelectedNormal)，以及用于基于节能(power saving，PS)的根据自主资源选择而进行侧行通信的发送资源池(TxPoolSelectedPSNormal)。其中，TxPoolSelectedNormal属于第一资源池，而TxPoolSelectedPSNormal属于第二资源池。
S102、终端装置获取物理层侧行链路共享信道PSSCH所对应的第一优先级值。
本实施例中，获取第一优先级值，该第一优先级值为PSSCH本身所对应的优先级，可以在相对应的SCI中指示，且该第一优先级值为第一终端装置获取的。在实际应用中，第一优先级值可以为PSSCH上承载的数据所对应的优先级，或者第一优先级值还可以为PSSCH上承载的数据业务所对应的优先级。
具体地，第一终端装置在slot n时刻产生待发送的PSSCH，通过前述实施例可知，可以获取到PSSCH所对应的优先级信息，该优先级信息即为第一优先级值。然后第一终端获取第一优先级阈值。
可选地，第一优先级阈值可以为资源池配置信息提供的，或者第一资源池信息提供的，或者预定义的，或者预配置的。在第一资源池信息还用于指示抢占信息时，第一优先级阈值还可以为抢占信息提供的，即第一优先级阈值和允许抢占的优先级阈值相等，具体第一优先级阈值的确定方式不应理解为方案的限定。
示例性地，第一优先级的取值范围可以为1至8中任一的整数值。第一优先级阈值取值也可以为1至8中任一的整数值，即可以取值为1，2，3，4，5，6，7或8，应理解，在实际应用中，第一优先级阈值取值可以为1至9中任一的整数值，即可以取值为1，2，3，4，5，6，7，8或9，可以理解的是，在实际应用中，当取值为9则表示不论第一优先级值为多少，均满足第一优先级值小于第一优先级阈值。第一优先级阈值取值还可以为1至16中任一的整数值，即可以取值为1至16之间的任何一个整数值，具体第一优先级阈值需要通过实际情况灵活确定，具体此处不做限定。应理解，前述示例仅用于理解本方案，具体处理方式应根据实际情况灵活执行。
进一步地，由于优先级数值越小表示所对应的优先级越高，即对应的QoS需求越高，因此判断PSSCH是否为高优先级，即需要判断PSSCH所对应的第一优先级值是否小于第一优先级阈值，第一优先级值小于第一优先级阈值时，执行步骤103，第一优先级值大于或等于第一优先级阈值时，执行步骤104。
S103、第一优先级值小于第一优先级阈值，终端装置确定在第一资源池以部分侦听选择资源确定方式和/或随机选择资源确定方式确定发送PSSCH的资源。
本实施例中，当待发送的PSSCH所对应的第一优先级值小于第一优先级阈值的情况下， 第一终端装置确定在第一资源池发送PSSCH。具体地，由于第一资源池为第一时频资源的集合，第一资源池原本为全侦听的资源确定方式，但是在PSSCH所对应的第一优先级值小于第一优先级阈值时，不采用全侦听的资源确定方式，变更为部分侦听的资源确定方式或者随机选择的资源确定方式，因此第一终端装置具体确定在第一资源池中以部分侦听选择和/或随机选择的方式确定发送PSSCH的第一时频资源。
可选地，在确定在第一资源池发送PSSCH的初始传输的频域资源带宽大小为一个子信道，进一步地，第一终端装置通过SCI来预约在初始传输之后重传的频域资源带宽为一个或多个子信道，具体地，SCI中可以携带PSCCH所占用的子信道个数信息，即后续重传PSSCH所需要的子信道个数。由于初传使用固定的最小的频域调度单元，即一个子信道，进行随机发送，则可以降低初始传输在频域上的碰撞概率。通过SCI来指示的重传的频域资源则不受子信道个数的限制，可以根据实际数据大小占用合适的子信道个数，包括大于一个子信道。其他终端装置(除了第一终端装置)则可以通过全侦听或部分侦听来获取该SCI的频域指示信息来避免资源选择的碰撞，进而提升传输的可靠性。
示例性地，由于第一优先级阈值可以通过不同方式确定，本实施例中以第一优先级阈值为资源池配置信息提供的，且第一资源池为TxPoolSelectedNormal，第二资源池为TxPoolSelectedPSNormal作为一个示例进行说明。以随机选择的资源确定方式为例，当待发送的PSSCH所对应的第一优先级值小于第一优先级阈值时，则表示第一终端装置可以在一个资源选择窗[n+T 1,n+T 2]中属于TxPoolSelectedNormal资源池中的资源随机选择一个第一时频资源发送PSSCH。具体地，在slot n时刻，该第一终端装置的物理层处理模块用于向第一终端装置的MAC层处理模块上报资源选择窗[n+T 1,n+T 2]时隙内属于TxPoolSelectedNormal资源池的全部时频候选资源(candidate resource)，用于MAC层处理模块随机选择一个候选资源，即第一资源，用于发送该PSSCH，其中一个候选单元包括1个时隙上的至少一个子信道资源用于发送该PSSCH。对于以部分侦听选择的方式确定发送PSSCH的第一资源，则通过侦听若干个slot，在资源选择窗[n+T 1,n+T 2]时隙内属于TxPoolSelectedNormal资源池的的资源，选择一个第一时频资源发送PSSCH。
具体地，资源选择窗中的T 1以及T 2的取值范围如下：
0≤T 1≤T proc，1；
T 2min≤T 2≤数据包时延预算；
T 1＜T 2
其中，T proc，1用于指示用户处理时延，T proc，1的最小取值可以为0，T 2min可以是网络装置配置的，或预配置的，或用户设备自主选择的，数据包时延预算(remaining packet delay budget，PDB)用于指示一个数据包从业务层产生到成功发送所需的最大的延时时间。其次，PDB可以是以时隙、子帧或帧等为单位的计量待发送数据时延的数值，也可以是以毫秒(ms)或秒(s)等为单位的计量待发送数据时延的数值，具体此处不做限定。
可以理解的是，在时隙n，剩余PDB(remaining PDB)为数据包从业务层产生到时隙n时所剩余的延时时间。示例性地，在时隙n，若剩余PDB为20ms，且一个时隙为0.5毫 秒，则在时隙n+1，剩余PDB为19.5ms，在时隙n+2，剩余PDB为19ms，在时隙n+3，剩余PDB为18.5ms，以此类推，具体不再赘述。应理解，前述示例仅用于理解本方案，具体数据发送的方式应根据实际情况灵活执行。
可选地，若以第一优先级阈值为预定义的作为示例，那么第一优先级阈值的取值可以为2，或者1至9之间的任何一个整数值，因优先级数值越小表示该优先级等级越高，第一优先级阈值的取值为2则代表只有优先级最高的PSCCH(即优先级值为1)才可以在TxPoolSelectedNormal资源池中进行部分侦听或随机选择资源的方式发送该PSSCH，以降低随机选择或者部分侦听选择对基于侦听进行选择的方式之间的干扰。
S104、第一优先级值大于或等于第一优先级阈值，终端装置确定在第二资源池部分侦听选择资源确定方式和/或随机选择资源确定方式确定发送PSSCH的资源。
本实施例中，当待发送的PSSCH所对应的第一优先级值大于或等于第一优先级阈值的情况下，第一终端装置确定在第二资源池发送PSSCH。由于第二资源池为第二时频资源的集合，因此第二终端装置具体确定在第二资源池中以以部分侦听选择和/或随机选择的方式确定发送PSSCH的第二时频资源。
示例性地，本实施例中以第一优先级阈值为资源池配置信息提供的，且第一资源池为TxPoolSelectedNormal，第二资源池为TxPoolSelectedPSNormal作为一个示例进行说明。当待发送的PSSCH所对应的第一优先级值大于或等于第一优先级阈值时，则表示第一终端装置可以在一个资源选择窗[n+T 1,n+T 2]中属于TxPoolSelectedPSNormal资源池中的资源随机选一个第二时频资源发送PSSCH，或者还可以通过部分侦听选择一个第二时频资源发送PSSCH。部分侦听选择资源的方式已在前述实施例中进行说明，在此不再赘述。
可选地，若以第一优先级阈值为预定义的作为示例，那么第一优先级阈值的取值可以为2，或者1至9之间的任何一个整数值，因优先级数值越小表示该优先级等级越高，第一优先级阈值的取值为2则代表只有优先级最高的PSCCH(即优先级值为1)才可以在TxPoolSelectedNormal资源池中进行部分侦听或随机选择资源的方式发送该PSSCH，以降低随机选择或者部分侦听选择对基于侦听进行选择的方式之间的干扰。
应理解，步骤103与步骤104无时序关系以及时序限定，即步骤103与步骤104为满足不同条件下所执行的步骤。
由前述实施例可知，高优先级的PSSCH(即小于第一优先级阈值的PSSCH)可以以部分侦听选择和/或随机选择的资源确定方式在全侦听选择的资源池中选择资源发送PSSCH，相当于在该资源池中允许全侦听选择，部分侦听选择和/或随机选择不同资源选择方式的共存。优先级较低的PSSCH(即大于或等于第一优先级阈值的PSSCH)，则以部分侦听选择和/或随机选择的资源确定方式在只能进行部分侦听选择和/或随机选择的资源池中选择资源发送PSSCH。
需要说明的是，第一资源池信息还用于指示随机选择配置信息，或者部分侦听选择配置信息，即第一终端装置可以在第一资源池中以随机选择的资源确定方式确定发送PSSCH的第一时频资源，或者还可以在第一资源池中以部分侦听选择的资源确定方式确定发送PSSCH的第一时频资源，下面分别对两种方式进行说明：
一、确定在第一资源池以随机选择的方式发送PSSCH。
本实施例中，第一终端装置可以确定在第一资源池以随机选择的方式发送PSSCH。为了便于理解，请参阅图4，图4为本申请实施例中数据传输的方法另一实施例示意图，如图所示，在该示例中，数据传输的方法包括如下步骤。
S201、终端装置获取资源池配置信息。
本实施例中，需要先获取资源池配置信息，该资源池配置信息为第一终端装置获取的，具体为第一终端装置接收网络装置所发送的资源池配置信息。具体资源池配置信息与前述实施例中的步骤S101所描述的类似，在此不再赘述。
进一步地，资源池配置信息中所包括的第一资源池信息还用于指示随机选择配置信息，且随机选择配置信息包括使能随机选择的资源确定方式，或，禁止使能随机选择的资源确定方式。
S202、终端装置获取PSSCH所对应的第一优先级值。
本实施例中，获取第一优先级值，该第一优先级值为PSSCH本身所对应的优先级，第一优先级可以在相对应的SCI中指示，且该第一优先级值为第一终端装置获取的。在实际应用中，第一优先级值可以为PSSCH上承载的数据所对应的优先级，或者第一优先级值还可以为PSSCH上承载的数据业务所对应的优先级。具体第一优先级值与前述实施例中的步骤S102所描述的类似，在此不再赘述。
S203、终端装置确定在第一资源池中以随机选择的资源确定方式确定发送PSSCH的资源。
本实施例中，由于第一资源池信息还用于指示随机选择配置信息，而第一资源池信息所指示的随机选择配置信息包括使能随机选择的资源确定方式，即随机选择配置信息被配置时，则表示第一终端装置可以在第一资源池中以随机选择的资源确定方式确定发送PSSCH的第一时频资源。或者，当第一资源池信息中的随机选择配置信息配置为使能随机选择的资源确定方式时，即第一终端装置可以在第一资源池中以随机选择的资源确定方式确定发送PSSCH的第一时频资源。进一步地，当随机选择配置信息没有被配置时，或第一资源池信息中的随机选择配置信息配置为禁止使能随机选择的资源确定方式时，即第一终端装置无法在第一资源池中以随机选择的资源确定方式确定发送PSSCH的第一时频资源。应理解，具体在第一资源池中以随机选择的资源确定方式确定发送PSSCH的第一时频资源的方式与前述前述实施例中的步骤S103所描述的类似，在此不再赘述。
示例性地，以第一资源池为TxPoolSelectedNormal作为一个示例进行说明，TxPoolSelectedNormal所对应的资源池信息包括使能随机选择的资源确定方式时，那么第一终端装置在TxPoolSelectedNormal资源池以随机选择的资源确定方式选择第一时频资源发送PSSCH，其次，TxPoolSelectedNormal所对应的资源池信息中随机选择配置信息配置为使能随机选择的资源确定方式时，第一终端装置也可以在TxPoolSelectedNormal资源池以随机选择的资源确定方式选择第一时频资源发送PSSCH。应理解，前述示例仅用于理解本方案，具体以随机选择的资源确定方式确定发送PSSCH的资源的方式应根据实际情况以及需求灵活执行。
S204、终端装置确定在第二资源池中以随机选择的资源确定方式确定发送PSSCH的资源。
本实施例中，由于第一资源池信息还用于指示随机选择配置信息，而第一资源池信息所指示的随机选择配置信息包括禁止使能随机选择的资源确定方式，即第一资源池信息中的随机选择配置信息没有被配置时，或第一资源池信息中的随机选择配置信息配置为禁止使能随机选择的资源确定方式时，即第一终端装置无法在第一资源池中以随机选择的资源确定方式确定发送PSSCH的第一时频资源。此时，第一终端装置可以在第二资源池中以随机选择的资源确定方式确定发送PSSCH的第二时频资源。应理解，具体在第二资源池中以随机选择的资源确定方式确定发送PSSCH的第二时频资源的方式与前述前述实施例中的步骤S104所描述的类似，在此不再赘述。
示例性地，本实施例中以第一资源池为TxPoolSelectedNormal，第二资源池为TxPoolSelectedPSNormal作为一个示例进行说明。TxPoolSelectedNormal所对应的资源池信息中随机选择配置信息没有被配置，或该随机选择配置信息配置为禁止使能随机选择的资源确定方式时，第一终端装置无法在TxPoolSelectedNormal资源池以随机选择的资源确定方式选择第一时频资源发送PSSCH，此时，第一终端装置可以在TxPoolSelectedNormal资源池以随机选择的资源确定方式选择第二时频资源发送PSSCH。应理解，前述示例仅用于理解本方案，具体以随机选择的资源确定方式确定发送PSSCH的资源的方式应根据实际情况以及需求灵活执行。
可选地，第一资源池信息还用于指示抢占信息，且抢占信息包括使能抢占的资源确定方式，或，禁止使能抢占的资源确定方式。
具体地，首先介绍抢占的资源确定方式，抢占即允许第一终端装置所发送的高优先级的PSSCH抢占第二终端装置发送的低优先级的PSSCH，第一终端装置与第二终端装置为不同的终端装置，且第一终端装置与第二终端装置都是确定以全侦听的资源确定方式进行资源选择的终端装置。因此第二终端装置在slot n时刻通过发送第一SCI预约了在slot n+k时刻发送PSSCH的资源，其优先级值为P1，第一终端装置在slot n时刻通过接收第一SCI，并对第一SCI进行译码可以得知第一SCI所预约的PSSCH优先级为P1，且预约slot n+k时刻发送PSSCH的资源。由于第一终端装置即将要发送PSSCH的优先级值为P2，且P2小于P1，即第一终端装置即将要发送PSSCH的优先级高于第二终端装置预约在slot n+k时刻发送PSSCH的优先级，此时第一终端装置将在slot n+k时刻前向第二终端装置发送第二SCI，以告知第二终端装置在slot n+k时刻所预约的资源被第一终端装置即将要发送PSSCH抢占，因此第二终端装置在接收到第二SCI后，需要重新进行资源的选择。
因此，由于随机选择的资源确定方式不基于侦听进行，即第一终端装置所发送的PSSCH可以在任何一个资源位置发送，而不会考虑其他终端装置是否有资源预约，因此，即使某个候选资源实际上被其他终端装置预约了，第一终端装置也可能选择在该候选资源发送PSSCH，因此第一终端装置不会进行侦听，即不会译码相应的SCI，所以随机选择的资源确定方式与抢占的资源确定方式类似，即抢占了某一个被预约的资源。本实施例中将第一资源池信息指示抢占信息与随机选择配置信息进行关联，因此第一资源池信息指示抢占信息时，可以包括两种数据传输的方式，一种方式为抢占信息为使能抢占的资源确定方式，且第一优先级值小于第一优先级阈值时，可以确定在第一资源池中以随机选择的资源确定方式确定发送PSSCH的资源。另一种方式为抢占信息为禁止使能抢占的资源确定方式，且第 一优先级值小于第一优先级阈值时，确定在第一资源池中以随机选择的资源确定方式确定发送PSSCH的资源。下面分别对两种方式进行说明。
(1)抢占信息为使能抢占的资源确定方式，且第一优先级值小于第一优先级阈值，确定在第一资源池中以随机选择的资源确定方式确定发送PSSCH的资源。
具体地，抢占信息为使能抢占的资源确定方式，即允许在第一资源池中以随机选择的资源确定方式发送PSSCH的资源，判断第一优先级值是否小于第一优先级阈值，在第一优先级值小于第一优先级阈值时，因此可以确定在第一资源池中以随机选择的资源确定方式确定发送PSSCH的第一时频资源。应理解，具体在第一资源池中以随机选择的资源确定方式确定发送PSSCH的第一时频资源的方式与前述前述实施例中的步骤S203所描述的类似，在此不再赘述。
示例性地，本实施例中以第一资源池为TxPoolSelectedNormal作为一个示例进行说明。所以当TxPoolSelectedNormal资源池信息所指示抢占信息的包括使能抢占的资源确定方式时，TxPoolSelectedNormal资源池所指示的抢占信息还提供第一优先级阈值，即允许发生抢占的PSSCH第一优先级值须小于第一优先级阈值，那么想要通过随机选择进行资源选择的第一终端装置所要待发送PSSCH优先级如果小于第一优先级阈值，则可以在TxPoolSelectedNormal资源池中以随机选择的资源确定方式确定发送PSSCH的第一时频资源，即随机选择资源确定方式以“抢占”的形式和全侦听资源确定方式在TxPoolSelectedNormal资源池中进行共存。应理解，前述示例仅用于理解本方案，具体第一资源池以及以随机选择的资源确定方式确定发送PSSCH的资源的方式应根据实际情况以及需求灵活确定。
其次，当抢占信息为使能抢占的资源确定方式，且第一优先级值大于或等于第一优先级阈值时，或抢占信息为禁止使能抢占的资源确定方式时，即第一终端装置确定在第二资源池中以随机选择的资源确定方式确定发送PSSCH的第二时频资源。具体在第二资源池中第一终端装置以随机选择的资源确定方式确定发送PSSCH的第二时频资源的方式与前述前述实施例中的步骤S204所描述的类似，在此不再赘述。
(2)抢占信息为禁止使能抢占的资源确定方式，且第一优先级值小于第一优先级阈值，确定在第一资源池中以随机选择的资源确定方式确定发送PSSCH的资源。
具体地，由于随机选择的资源确定方式对全侦听选择的资源确定方式而言会造成性能影响，抢占也可能也会对全侦听选择的资源确定方式造成影响，因此通过前述方式同时允许抢占和随机选择的资源确定的方式会增加对全侦听资源确定方式的影响，即在第一资源池中进行会提升PSSCH的碰撞概率。因此本方式在第一资源池信息指示禁止使能抢占的资源确定方式，且第一优先级值小于第一优先级阈值时，第一终端装置才确定在第一资源池中以随机选择的资源确定方式确定发送高优先级的PSSCH所对应的资源，而其他情况下第一终端装置均在第二资源池中以随机选择的资源确定方式确定发送PSSCH的资源，由此可以降低随机选择、抢占和权侦听之间的干扰和冲突影响，从而降低对随机选择的资源确定方式发送高优先级PSSCH的碰撞，进而能够保证优先级较高的PSSCH的QoS。
因此，抢占信息为禁止使能抢占的资源确定方式，且在第一优先级值小于第一优先级阈值时，第一终端装置可以确定在第一资源池中以随机选择的资源确定方式确定发送PSSCH 的第一时频资源。应理解，具体在第一资源池中以随机选择的资源确定方式确定发送PSSCH的第一时频资源的方式与前述前述实施例中的步骤S203所描述的类似，在此不再赘述。
示例性地，本实施例中以第一资源池为TxPoolSelectedNormal作为一个示例进行说明。所以当TxPoolSelectedNormal资源池信息所指示抢占信息的包括禁止使能抢占的资源确定方式时，那么第一终端装置无法在TxPoolSelectedNormal资源池进行抢占，即第一终端装置所要待发送PSSCH优先级小于第一优先级阈值，可以在TxPoolSelectedNormal资源池中以随机选择的资源确定方式确定发送PSSCH的第一时频资源。应理解，前述示例仅用于理解本方案，具体第一资源池以及以随机选择的资源确定方式确定发送PSSCH的资源的方式应根据实际情况以及需求灵活确定。
其次，当抢占信息为禁止使能抢占的资源确定方式，且第一优先级值大于或等于第一优先级阈值时，或抢占信息为使能抢占的资源确定方式时，即确定在第二资源池中以随机选择的资源确定方式确定发送PSSCH的第二时频资源。具体在第二资源池中以随机选择的资源确定方式确定发送PSSCH的第二时频资源的方式与前述前述实施例中的步骤S204所描述的类似，在此不再赘述。
二、确定在第一资源池以部分侦听选择的方式发送PSSCH。
本实施例中，第一终端装置可以确定在第一资源池以部分侦听选择的方式发送PSSCH。为了便于理解，请参阅图5，图5为本申请实施例中数据传输的方法另一实施例示意图，如图所示，在该示例中，数据传输的方法包括如下步骤。
S301、终端装置获取资源池配置信息。
本实施例中，需要先获取资源池配置信息，该资源池配置信息为第一终端装置获取的，具体为第一终端装置接收网络装置所发送的资源池配置信息。具体资源池配置信息与前述实施例中的步骤S101所描述的类似，在此不再赘述。
进一步地，资源池配置信息中所包括的第一资源池信息还用于指示部分侦听选择配置信息，且部分侦听选择配置信息包括使能部分侦听选择的资源确定方式，或，禁止使能部分侦听选择的资源确定方式。
S302、终端装置获取PSSCH所对应的第一优先级值。
本实施例中，获取第一优先级值，该第一优先级值为PSSCH本身所对应的优先级，第一优先级可以在相对应的SCI中指示，该第一优先级值为第一终端装置获取的。在实际应用中，第一优先级值可以为PSSCH上承载的数据所对应的优先级，或者第一优先级值还可以为PSSCH上承载的数据业务所对应的优先级。具体第一优先级值与前述实施例中的步骤S102所描述的类似，在此不再赘述。
S303、终端装置确定在第一资源池中以部分侦听选择的资源确定方式确定发送PSSCH的资源。
本实施例中，由于第一资源池信息还用于指示部分侦听选择配置信息，而第一资源池信息所指示的部分侦听选择配置信息包括使能部分侦听选择的资源确定方式，即部分侦听选择配置信息被配置时，则表示第一终端装置可以在第一资源池中以部分侦听选择的资源确定方式确定发送PSSCH的第一时频资源。或者，当第一资源池信息中的部分侦听选择配置信息配置为使能部分侦听选择的资源确定方式时，即第一终端装置可以在第一资源池中 以部分侦听选择的资源确定方式确定发送PSSCH的第一时频资源。进一步地，当部分侦听选择配置信息没有被配置时，或第一资源池信息中的部分侦听选择配置信息配置为禁止使能部分侦听选择的资源确定方式时，即第一终端装置无法在第一资源池中以部分侦听选择的资源确定方式确定发送PSSCH的第一时频资源。应理解，具体在第一资源池中以部分侦听选择的资源确定方式确定发送PSSCH的第一时频资源的方式与前述前述实施例中的步骤S103所描述的类似，在此不再赘述。
示例性地，以第一资源池为TxPoolSelectedNormal作为一个示例进行说明，TxPoolSelectedNormal所对应的资源池信息包括使能部分侦听选择的资源确定方式时，那么第一终端装置在TxPoolSelectedNormal资源池以部分侦听选择的资源确定方式选择第一时频资源发送PSSCH，其次，TxPoolSelectedNormal所对应的资源池信息中部分侦听选择配置信息配置为使能部分侦听选择的资源确定方式时，第一终端装置也可以在TxPoolSelectedNormal资源池以部分侦听选择的资源确定方式选择第一时频资源发送PSSCH。应理解，前述示例仅用于理解本方案，具体以部分侦听选择的资源确定方式确定发送PSSCH的资源的方式应根据实际情况以及需求灵活执行。
S304、终端装置确定在第二资源池中以部分侦听选择的资源确定方式确定发送PSSCH的资源。
本实施例中，由于第一资源池信息还用于指示部分侦听选择配置信息，而第一资源池信息所指示的部分侦听选择配置信息包括禁止使能部分侦听选择的资源确定方式，即第一资源池信息中的部分侦听选择配置信息没有被配置时，或第一资源池信息中的部分侦听选择配置信息配置为禁止使能部分侦听选择的资源确定方式时，即第一终端装置无法在第一资源池中以部分侦听选择的资源确定方式确定发送PSSCH的第一时频资源。此时，第一终端装置可以在第二资源池中以部分侦听选择的资源确定方式确定发送PSSCH的第二时频资源。应理解，具体在第二资源池中以部分侦听选择的资源确定方式确定发送PSSCH的第二时频资源的方式与前述前述实施例中的步骤S104所描述的类似，在此不再赘述。
示例性地，本实施例中以第一资源池为TxPoolSelectedNormal，第二资源池为TxPoolSelectedPSNormal作为一个示例进行说明。TxPoolSelectedNormal所对应的资源池信息中部分侦听选择配置信息没有被配置，或该部分侦听选择配置信息配置为禁止使能部分侦听选择的资源确定方式时，第一终端装置无法在TxPoolSelectedNormal资源池以部分侦听选择的资源确定方式选择第一时频资源发送PSSCH，此时，第一终端装置可以在TxPoolSelectedNormal资源池以部分侦听选择的资源确定方式选择第二时频资源发送PSSCH。应理解，前述示例仅用于理解本方案，具体以部分侦听选择的资源确定方式确定发送PSSCH的资源的方式应根据实际情况以及需求灵活执行。
可选地，第一资源池信息还用于指示抢占信息，抢占信息包括使能抢占的资源确定方式，或，禁止使能抢占的资源确定方式。
具体地，由于部分帧听选择的资源确定方式是在若干个时间单元上进行侦听，即第一终端装置所发送的PSSCH只会根据部分侦听的结果来确定一个资源位置发送，而不会考虑未被侦听的时间单元上其他终端装置是否有有发送SCI来进行资源预约，因此，即使某个候选资源实际上被其他终端装置预约了，但第一终端装置仅根据在该若干个时间单元上获 得的部分侦听的结果选择了该候选资源，即第一终端装置选择在该候选资源发送PSSCH，因此在这种情况，部分帧听选择的资源确定方式相当于抢占了某一个被预约的资源。本实施例中将第一资源池信息指示抢占信息与部分帧听选择配置信息进行关联，因此第一资源池信息指示抢占信息时，可以包括两种数据传输的方式，一种方式为抢占信息为使能抢占的资源确定方式，第一优先级值小于第一优先级阈值时，可以确定在第一资源池中以部分帧听选择的资源确定方式确定发送PSSCH的资源。另一种方式为抢占信息为禁止使能抢占的资源确定方式，第一优先级值小于第一优先级阈值时，确定在第一资源池中以部分帧听选择的资源确定方式确定发送PSSCH的资源。下面分别对两种方式进行说明。
(1)抢占信息为使能抢占的资源确定方式，且第一优先级值小于第一优先级阈值，确定在第一资源池中以部分侦听选择的资源确定方式确定发送PSSCH的资源。
具体地，抢占信息为使能抢占的资源确定方式，即允许在第一资源池中以部分侦听选择的资源确定方式发送PSSCH的资源，判断第一优先级值是否小于第一优先级阈值，在第一优先级值小于第一优先级阈值时，因此可以确定在第一资源池中以部分侦听选择的资源确定方式确定发送PSSCH的第一时频资源。应理解，具体在第一资源池中以部分侦听选择的资源确定方式确定发送PSSCH的第一时频资源的方式与前述前述实施例中的步骤S303所描述的类似，在此不再赘述。
示例性地，本实施例中以第一资源池为TxPoolSelectedNormal作为一个示例进行说明。所以当TxPoolSelectedNormal资源池信息所指示抢占信息的包括使能抢占的资源确定方式时，TxPoolSelectedNormal资源池所指示的抢占信息还提供第一优先级阈值，即允许发生抢占的PSSCH第一优先级值须小于第一优先级阈值，那么想要通过部分侦听选择进行资源选择的第一终端装置所要待发送PSSCH优先级如果小于第一优先级阈值，则可以在TxPoolSelectedNormal资源池中以部分侦听选择的资源确定方式确定发送PSSCH的第一时频资源，即部分侦听选择资源确定方式以“抢占”的形式和全侦听资源确定方式在TxPoolSelectedNormal资源池中进行共存。应理解，前述示例仅用于理解本方案，具体第一资源池以及以部分侦听选择的资源确定方式确定发送PSSCH的资源的方式应根据实际情况以及需求灵活确定。
其次，当抢占信息为使能抢占的资源确定方式，且第一优先级值大于或等于第一优先级阈值时，或抢占信息为禁止使能抢占的资源确定方式时，即第一终端装置确定在第二资源池中以部分侦听选择的资源确定方式确定发送PSSCH的第二时频资源。具体在第二资源池中以部分侦听选择的资源确定方式确定发送PSSCH的第二时频资源的方式与前述前述实施例中的步骤S304所描述的类似，在此不再赘述。
(2)抢占信息为禁止使能抢占的资源确定方式，且第一优先级值小于第一优先级阈值，确定在第一资源池中以部分侦听选择的资源确定方式确定发送PSSCH的资源。
具体地，由于部分侦听选择的资源确定方式对全侦听选择的资源确定方式而言会造成性能影响，抢占也可能也会对全侦听选择的资源确定方式造成影响，因此通过前述方式同时抢占和部分侦听选择的资源确定的方式会增加对全侦听资源确定方式的影响，即在第一资源池中进行会提升PSSCH的碰撞概率。因此本方式在第一资源池信息指示禁止使能抢占的资源确定方式，且第一优先级值小于第一优先级阈值时，第一终端装置才确定在第一资 源池中以部分侦听选择的资源确定方式确定发送高优先级的PSSCH所对应的资源，而其他情况下均在第二资源池中以部分侦听选择的资源确定方式确定发送PSSCH的资源，由此可以降低部分侦听选择以及抢占之间的干扰和冲突影响，从而降低对部分侦听选择的资源确定方式发送高优先级PSSCH的碰撞，进而能够保证优先级较高的PSSCH的QoS。
因此，抢占信息为禁止使能抢占的资源确定方式，且在第一优先级值小于第一优先级阈值时，因此第一终端装置可以确定在第一资源池中以部分侦听选择的资源确定方式确定发送PSSCH的第一时频资源。应理解，具体在第一资源池中以部分侦听选择的资源确定方式确定发送PSSCH的第一时频资源的方式与前述前述实施例中的步骤S303所描述的类似，在此不再赘述。
示例性地，本实施例中以第一资源池为TxPoolSelectedNormal作为一个示例进行说明。所以当TxPoolSelectedNormal资源池信息所指示抢占信息的包括禁止使能抢占的资源确定方式时，那么第一终端装置无法在TxPoolSelectedNormal资源池进行抢占，即第一终端装置所要待发送PSSCH优先级小于第一优先级阈值，可以在TxPoolSelectedNormal资源池中以部分侦听选择的资源确定方式确定发送PSSCH的第一时频资源。应理解，前述示例仅用于理解本方案，具体第一资源池以及以部分侦听选择的资源确定方式确定发送PSSCH的资源的方式应根据实际情况以及需求灵活确定。
其次，当抢占信息为禁止使能抢占的资源确定方式，且第一优先级值大于或等于第一优先级阈值时，或抢占信息为使能抢占的资源确定方式时，即确定在第二资源池中以部分侦听选择的资源确定方式确定发送PSSCH的第二时频资源。具体在第二资源池中以部分侦听选择的资源确定方式确定发送PSSCH的第二时频资源的方式与前述前述实施例中的步骤S304所描述的类似，在此不再赘述。
在前述实施例中，介绍了第一终端装置确定在第一资源池发送PSSCH的方式，进一步地，第一终端装置应在满足下述三种条件中的任一条件时，确定在第一资源池以部分侦听选择资源确定方式和/或随机选择资源确定方式确定发送PSSCH的资源。
第一种条件，PSSCH所对应的发送功率小于或等于发送功率阈值。
具体地，发送功率阈值可以根据网络装置配置得到，或者通过预配置得到，或者基于其他终端装置通过SCI指示得到，或者基于第二终端装置通过SL MAC CE配置得到的。在实际应用中，发送功率阈值还可以第二终端装置通过侧行通信无线资源控制配置得到，或，出厂设置得到，或，预定义得到。具体地，第二终端装置与第一终端装置为不同的终端装置，侧行通信无线资源控制可以为PC5-RRC。因此具体电量阈值需要根据实际情况灵活确定。
在一种可能的实施方式中，发送功率阈值还可以与拥塞控制参数以及服务质量参数中至少一项参数相关。具体地，拥塞控制参数可以为CRB，而服务质量参数包括但不限于通信距离，地理位置信息以及PSSCH的优先级信息等，其中通信距离可以包括最小通信距离，地理位置信息可以包括区域标识指示信息＝，具体此处不做限定。
第二种条件，第一终端装置电池余量小于或等于电量阈值。
具体地，电量阈值可以根据网络装置配置得到，或者通过预配置得到，或者基于其他终端装置通过SCI指示得到，或者基于第二终端装置通过SL MAC CE配置得到的。在实际 应用中，电量阈值还可以第二终端装置通过侧行通信无线资源控制配置得到，或，出厂设置得到，或，预定义得到。具体地，第二终端装置与第一终端装置为不同的终端装置，侧行通信无线资源控制可以为PC5-RRC。因此具体电量阈值需要根据实际情况灵活确定。

下面将以网络装置为执行主体对本申请实施例使用的数据传输的方法进行详细描述，请参阅图6，图6为本申请实施例中数据传输的方法一个实施例的示意图，数据传输的方法包括如下步骤。
S401、网络装置发送资源池配置信息。
本实施例中，发送资源池配置信息，具体为网络装置向第一终端装置发送资源池配置信息。其中，资源池配置信息包括第一资源池信息以及第二资源池信息，第一资源池信息用于指示第一资源池，而第二资源池信息用于指示第二资源池，第一资源池与第二资源池为不同类型的资源池，第一资源池为第一时频资源的集合，而第二资源池为第二时频资源的集合，第一资源池的资源确定方式包括全侦听，而第二资源池的资源确定方式包括部分侦听选择以及随机选择。其次，资源池配置信息还可以用于指示N个发送资源池以及P个接收资源池，由于发送资源池用于发送SL，而接收资源池用于接收SL，因此所配置的接收资源池的总数量大于或等于配置的发送资源池的总数量，即P大于或等于N，由此使得第一终端装置可以尽可能地收到来自不同发送资源池发送的数据。应理解，在实际应用中，第一资源池的资源确定方式还可以包括部分侦听选择以及随机选择，具体此处不做限定。
具体地，第一终端装置接收到资源池配置信息后，还可以获取PSSCH所对应的第一优先级值，然后判断第一优先级值与第一优先级阈值的大小。当第一优先级值小于第一优先级阈值时，第一终端装置确定在第一资源池发送PSSCH，或者第一优先级值大于或等于第一优先级阈值时，确定在第二资源池部分侦听选择资源确定方式和/或随机选择资源确定方式确定发送PSSCH的资源。其中，第一优先级阈值可以为资源池配置信息提供的，或者第一资源池信息提供的。
可选地，第一资源池信息还用于指示随机选择配置信息，随机选择配置信息包括使能随机选择的资源确定方式，或，禁止使能随机选择的资源确定方式。第一终端装置接收到指示随机选择配置信息的第一资源池信息，可以在不同条件下确定在不同的资源池中以随 机选择的资源确定方式确定发送PSSCH的资源。具体确定在第一资源池中以随机选择的资源确定方式确定发送PSSCH的资源的方式，以及确定在第二资源池中以随机选择的资源确定方式确定发送PSSCH的资源的方式在第一终端装置为执行主体所介绍的本实施例中已进行介绍，在此不再赘述。
可选地，第一资源池信息还用于指示抢占信息，抢占信息包括使能抢占的资源确定方式，或，禁止使能抢占的资源确定方式。第一终端装置接收到指示抢占信息的第一资源池信息，也可以在不同条件下确定在不同的资源池中以随机选择的资源确定方式确定发送PSSCH的资源。此时，抢占信息还可以提供第一优先级阈值。具体确定在第一资源池中以随机选择的资源确定方式确定发送PSSCH的资源的方式，以及确定在第二资源池中以随机选择的资源确定方式确定发送PSSCH的资源的方式在第一终端装置为执行主体所介绍的本实施例中已进行介绍，在此不再赘述。
可选地，第一资源池信息还用于指示部分侦听选择配置信息，部分侦听选择配置信息包括使能部分侦听选择的资源确定方式，或，禁止使能部分侦听选择的资源确定方式。第一终端装置接收到指示部分侦听选择配置信息的第一资源池信息，可以在不同条件下确定在不同的资源池中以部分侦听选择的资源确定方式确定发送PSSCH的资源。具体确定在第一资源池中以部分侦听选择的资源确定方式确定发送PSSCH的资源的方式，以及确定在第二资源池中以部分侦听选择的资源确定方式确定发送PSSCH的资源的方式在第一终端装置为执行主体所介绍的本实施例中已进行介绍，在此不再赘述。
可选地，第一资源池信息还用于指示抢占信息，抢占信息包括使能抢占的资源确定方式，或，禁止使能抢占的资源确定方式。第一终端装置接收到指示抢占信息的第一资源池信息，也可以在不同条件下确定在不同的资源池中以部分侦听选择的资源确定方式确定发送PSSCH的资源。具体确定在第一资源池中以部分侦听选择的资源确定方式确定发送PSSCH的资源的方式，以及确定在第二资源池中以部分侦听选择的资源确定方式确定发送PSSCH的资源的方式在第一终端装置为执行主体所介绍的本实施例中已进行介绍，在此不再赘述。
上述主要以方法的角度对本申请实施例提供的方案进行了介绍。可以理解的是，数据传输装置以及资源池配置信息的配置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。本领域技术人员应该很容易意识到，结合本文中所公开的实施例描述的各示例的模块及算法步骤，本申请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。专业技术人员可以对每个特定的应用来使用不同方法来实现所描述的功能，但是这种实现不应认为超出本申请的范围。
本申请实施例可以基于上述方法示例对数据传输装置以及资源池配置信息的配置装置进行功能模块的划分，例如，可以对应各个功能划分各个功能模块，也可以将两个或两个以上的功能集成在一个处理模块中。上述集成的模块既可以采用硬件的形式实现，也可以采用软件功能模块的形式实现。需要说明的是，本申请实施例中对模块的划分是示意性的，仅仅为一种逻辑功能划分，实际实现时可以有另外的划分方式。
