资源处理方法、装置及存储介质
本申请要求于2020年11月03日提交中国专利局、申请号为202011210192.0、申请名称为“一种资源预留和选择方法”的中国专利申请的优先权，且要求于2021年02月03日提交中国专利局、申请号为202110153049.0、申请名称为“资源处理方法、装置及存储介质”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及通信技术领域，尤其涉及一种资源处理方法、装置及存储介质。
背景技术
在3GPP侧行链路(Sidelink，SL)R16版本中，有两种资源分配模式：模式(Mode)1和模式2。在模式1下，处于基站(gNB)覆盖范围下的侧行链路设备进行数据传输的资源需要通过物理层信令或者媒体访问控制层(Media Access Control)或者无线资源控制(Radio Resource Control，RRC)信令向基站申请，其中侧行链路设备也称为侧行链路用户设备(user equipment，UE)。基站为侧行链路发送端设备(简称为：发送端设备)以及其对应的侧行链路接收端设备(简称为：接收端设备)分配一定的时频资源进行数据传输。由于在模式1下，有基站对所有侧行链路传输进行集中式资源调度，能有效地避免侧行链路网络中的干扰和冲突问题。但是在模式1下资源分配主要依赖于基站，同时侧行链路设备申请资源的过程需要多次交互，会导致较长的时延，对于一些无基站或者时延要求比较高的场景不适用，比如车联网(Vehicle to Everything，V2X)。
在模式2下，侧行链路传输的资源由发送端设备通过信道感知和选择(sensing and selection)来决定。比如，各发送端设备在发送信息时，会在其绑定的第一阶侧行链路控制信息(Sidelink control information，SCI)指示其占用的时频资源。指示的时频资源包含两部分，第一部分是为当前侧行链路物理共享信道(Physical sidelink shared channel，PSSCH)上的数据的初传和混合自动重传请求(Hybrid Automatic Repeat reQuest，HARQ)重传预留的资源；第二部分是为周期性业务数据预留的时频资源。基于此，某一发送端设备想要发送数据前，为了确定可用的时频资源，需要检测感知窗口(sensing window)内其他侧行链路设备的SCI，若检测到SCI的接收功率超过与该SCI优先级相关联的功率门限值，则将该SCI预留的资源从资源池中去除。若将所有被预留的资源去除后，剩余的资源占资源池总资源的比重小于第一预设值(比如0.2)，则将与各优先级相关联的功率门限提高第二预设值(比如3dB)，然后重复以上步骤，直至剩余的资源占资源池总资源的比重不小于第一预设值。最后根据感知结果在可用的资源上选取时频资源位置发送数据。在模式2下资源分配由各侧行链路设备自主完成，不需要基站参与调度，能适应的场景更加广泛，同时感知和选择行为均在各侧行链路设备处本地执行，所需时长也很短，能对业务做出较快的响应。
但是，在模式2下资源分配方案为分布式方案，且资源的感知过程和预留过程(发送SCI)仅在各发送端设备处执行，由于发送端设备和接收端设备的位置和信道环境的不同，发送端设备感知的结果并不一定能保证侧行链路场景下资源分配的合理性，严重时可能会导致隐藏终端问题和暴露问题。
发明内容
有鉴于此，提出了一种资源处理方法、装置及存储介质。本申请实施例通过发送端设备和接收端设备都发送SCI来对信道资源进行预留，以及都进行感知和检测，使得侧行链路场景下的资源分配方案得到增强，解决了隐藏终端问题和暴露终端问题，降低了侧行链路干扰和冲突情况，同时提高了侧行链路中的空间复用效率。
第一方面，本申请的实施例提供了一种资源处理方法，用于第一设备中，该方法包括：
接收第一SCI，第一SCI的类型为第一类型，第一SCI包括第一指示信息，第一指示信息指示第一时频资源，第一指示信息还指示第一设备发送第二SCI；
发送第二SCI，第二SCI的类型为第二类型，第二SCI包括第二指示信息，第二指示信息指示第二时频资源；
其中，第一时频资源是为第二设备所预留的用于向第一设备发送数据的时频资源，或者，第一时频资源是为第二设备所预留的用于向第一设备发送数据、且为第一设备所预留的用于接收数据的时频资源；第二时频资源是为第一设备所预留的用于接收数据的时频资源，第一时频资源包括第二时频资源。
在该实现方式中，第一SCI包括的第一指示信息指示第一时频资源，第一时频资源是为第二设备所预留的用于向第一设备发送数据的时频资源，或者指示为第二设备所预留的用于向第一设备发送数据、且为第一设备所预留的用于接收数据的时频资源；在第一设备发送第二SCI之前，第一SCI向其他设备指示第一时频资源是为第二设备所预留的用于向第一设备发送数据、且为第一设备所预留的用于接收数据的时频资源，其他设备在第一时频资源上接收数据会受到第二设备干扰，在第一时频资源上发送数据可能会对第一设备的接收产生干扰，在第一设备发送第二SCI之后，第一SCI向其他设备指示第一时频资源是为第二设备所预留的用于向第一设备发送数据的时频资源，在第一时频资源上接收数据会受到第二设备干扰，由于第二SCI已经对其他设备的发送行为进行指示，故第一SCI对其他设备的发送行为不再做指示；第二SCI包括的第二指示信息指示第二时频资源，第二时频资源是为第一设备所预留的用来接收数据的时频资源，从而向其他设备指示在第二时频资源上发送数据会对该第一设备产生干扰，对其他设备的接收行为不做指示。该方案使得侧行链路场景下的资源分配方案得到增强，发送端设备(即第二设备)和接收端设备(即第一设备)都发送SCI，从而在收发两端都能够对资源进行预留，解决了隐藏终端问题，降低了侧行链路干扰和冲突情况，并且，发送端设备预留资源不影响其他设备的发送行为，接收端设备预留资源不影响其他设备的接收行为，解决了暴露终端问题，同时提高了侧行链路中的空间复用效率。
在一种可能的实现方式中，第一SCI还包括数据的第一业务优先级的指示信息、 指示第一设备的设备标识的信息、指示第二设备的设备标识的信息；第二SCI还包括数据的第二业务优先级的指示信息和指示第二设备的设备标识的信息，第二业务优先级是根据第一业务优先级确定的。

在该实现方式中，第一设备发送第二SCI的时刻与第一设备接收第一SCI的时刻的差值绝对值小于或等于第一时间门限，即第一设备在接收到第一SCI后，需要在第一时间门限内发送第二SCI，保证其他设备根据第一SCI的接收时间与当前时间的差值来判断第一设备是否已经发送第二SCI，从而判断第一SCI中预留的资源是仅为第二设备发送数据预留的资源，还是为第一设备接收数据和第二设备发送数据预留的资源。

在该实现方式中，第二设备发送第三SCI为自己的发送行为进行资源预留，使得 收到第一SCI和第三SCI的其他设备在对第二设备干扰不大于某个阈值的情况下可以和第二设备共用时频资源进行数据发送，避免了暴露终端问题，提高了侧行链路中的空间复用效率。

具体实施方式
以下将参考附图详细说明本申请的各种示例性实施例、特征和方面。附图中相同的附图标记表示功能相同或相似的元件。尽管在附图中示出了实施例的各种方面，但是除非特别指出，不必按比例绘制附图。
在这里专用的词“示例性”意为“用作例子、实施例或说明性”。这里作为“示例性”所说明的任何实施例不必解释为优于或好于其它实施例。
另外，为了更好的说明本申请，在下文的具体实施方式中给出了众多的具体细节。本领域技术人员应当理解，没有某些具体细节，本申请同样可以实施。在一些实例中，对于本领域技术人员熟知的方法、手段、元件和电路未作详细描述，以便于凸显本申请的主旨。
相关技术中，在3GPP侧行链路R16版本中，资源分配模式为模式2时，各发送端设备在发送数据时，并在其绑定的SCI上指示被预留的时频资源。比如该SCI为第一阶SCI(SCI-1)，SCI-1包括指示信息，指示信息指示的时频资源包含两部分，第一部分是为当前PSSCH上的数据的初传和HARQ重传预留的资源；第二部分是为周期性业务数据预留的时频资源。基于此，某一发送端设备想要发送数据前，为了确定可用的时频资源，需要检测感知窗口内其他侧行链路设备的SCI，根据感知结果在可用的资源上选取时频资源位置发送数据。在模式2下资源分配方案为分布式方案，且资源的感知过程和预留过程仅在各发送端设备处执行，由于发送端设备和接收端设备的位置和信道环境的不同，发送端设备感知的结果并不一定能保证侧行链路场景下资源分配的合理性和准确性，严重时可能会导致隐藏终端问题和暴露终端问题。
在一个示意性的例子，如图1所示，发送端设备T1正向接收端设备R1发送数据，并在其发送的SCI上指示了时频资源S1已被预留。同时发送端设备T2需要向接收端设备R2发送数据，而在目前的模式2下，由于T2和T1相隔较远，T2无法检测到T1发送的SCI，于是会认为该时频资源S1可用，故在时频资源S1即同一时频资源上向R2发送数据，而由于T2和R1距离较近，R1会受到T2的强干扰，无法成功接收T1发送的数据，造成隐藏终端问题。
在另一个示意性的例子，如图2所示，发送端设备T1正向接收端设备R1发送数据，并在其发送的SCI上指示了时频资源S1已被预留。同时发送端设备T2需要向接收端设备R2发送数据，而在目前的模式2下，由于T2和T1相隔很近，T2检测到了T1发送的SCI，于是会认为该时频资源S1被占用，故无法在时频资源S1即同一时频资源上向R2发送数据。然而事实上在该拓扑结构下T2无法对R1产生干扰，T1也无法对R2产生干扰，即T1向R1发送数据和T2向R2发送数据是可以实现空间复用的，而T2因为T1的SCI指示导致对干扰情况产生了过渡保守的判断，造成了暴露终端问题。
本申请实施例提供了一种资源处理方法，发送端设备和接收端设备都发送SCI来对信道资源进行预留，能避免隐藏终端问题，提高传输可靠性。同时在资源感知和选择阶段，收发两端同时提供了对不同资源上干扰的判断，有助于选择干扰更小的信道进行发送，同时收发两端对于发送干扰和接受干扰进行区分，从而能避免暴露终端问 题，提高了侧行链路中的空间复用效率，提升了频谱效率。
本申请实施例的技术方案可以应用于各种通信系统，比如：无线保真(wifi)、全球微波互联接入(Worldwide Interoperability for Microwave Access，WiMAX)、全球移动通讯(Global System of Mobile communication，GSM)系统、码分多址(Code Division Multiple Access，CDMA)系统、宽带码分多址(Wideband Code Division Multiple Access，WCDMA)系统、通用分组无线业务(General Packet Radio Service，GPRS)、长期演进(Long Term Evolution，LTE)系统、先进的长期演进(Advanced long term evolution，LTE-A)系统、通用移动通信系统(Universal Mobile Telecommunication System，UMTS)、以及第三代合作伙伴计划(The 3rd Generation Partnership Project，3GPP)相关的蜂窝系统等，以及第五代移动通信系统(The Fifth Generation,5G)。本申请实施例可以应用于5G侧行链路系统或5G演进侧行链路系统中。本申请实施例并不限定。

在车联网的业务场景中，第一设备为第一车辆32的车载设备，第二设备为第二车辆34的车载设备。第一设备和第二设备是进行侧行链路通信的两端设备，第一设备和第二设备之间可以通过侧行链路通信接口(如PC5接口)建立侧行链路，然后通过该侧行链路进行用户面数据和控制面信令的交互。与基于Uu接口通信相比，基于侧行链路通信接口通信具有时延短、开销小等特点，适合用于车载设备和地理位置接近的其它周边设备之间的通信。
上述图3所示的网络架构可以实现V2X业务场景，上述网络架构中还可以包括RSU、V2X应用服务器、V2X控制功能节点等设备，本申请实施例对此不作限定。

在智能家居的业务场景中，第一设备为第一智能家居设备42，第二设备为第二智能家居设备44。第一设备和第二设备是进行侧行链路通信的两端设备，第一设备和第二设备之间可以通过侧行链路通信接口(如PC5接口)建立侧行链路，然后通过该侧行链路进行用户面数据和控制面信令的交互。

在本申请实施例中，针对上述车联网、智能家居或其他业务场景中的侧行链路通信过程，提供了一种资源处理方法，以解决上述隐藏终端问题和暴露终端问题。
下面，通过几个示例性实施例对本申请技术方案进行介绍说明。
需要说明的是，本申请实施例中SCI的分类方式包括如下两种：一种可能的分类方式为，SCI的类型包括第一类型、第二类型和第三类型。另一种可能的分类方式为，SCI的类型包括第一类型和第二类型。每种类型的SCI所指示的含义如下文所述。
第一类型的SCI所指示的时频资源是为发送端设备所预留的用于发送数据的时频资源，或者，是为发送端设备所预留的用于发送数据、且为接收端设备所预留的用于接收数据的时频资源。
第一种可能的情况中，在与该发送端设备对端的接收端设备发送与该第一类型的SCI对应的第二类型的SCI之前，第一类型的SCI所指示的时频资源是为发送端设备所预留的用于发送数据、且为其对端的接收端设备所预留的用于接收数据的时频资源，从而向其他设备指示在该时频资源上接收数据会收到该发送端设备干扰，在该时频资源上发送数据可能会对其对端的接收端设备产生干扰。其中，其他设备是除该发送端设备和对应的接收端设备外的设备。
在一种可能的实现方式中，其他设备接收到一个第一类型的SCI且在第一时间门限内未接收到该第一类型的SCI对应的第二类型的SCI，则表示与该第一类型的SCI对应的第二类型SCI可能尚未发送，确定第一类型的SCI所指示的时频资源是为发送端设备所预留的用于发送数据、且为其对端的接收端设备所预留的用于接收数据的时频资源。
第二种可能的情况中，在该发送端设备对端的接收端设备发送与该第一类型的SCI对应的第二类型的SCI之后，第一类型的SCI所指示的时频资源是为发送端设备所预留的用于发送数据的时频资源，从而向其他设备指示在该时频资源上接收数据会收到该发送端设备的干扰，而对其他设备能否在该时频资源上发送数据不做指示。
在一种可能的实现方式中，其他设备接收到一个第一类型的SCI且在第一时间门限内接收到该第一类型的SCI对应的第二类型的SCI，则表示与该第一类型的SCI对应的第二类型SCI已发送，确定第一类型的SCI所指示的时频资源是为发送端设备所预留的用于发送数据的时频资源。
在另一种可能的实现方式中，其他设备接收到两个第一类型的SCI且这两个第一类型的SCI的间隔大于第一时间门限，则表示与该第一类型的SCI对应的第二类型SCI已发送，确定第一类型的SCI所指示的时频资源是为发送端设备所预留的用于发送数据的时频资源。
在另一种可能的实现方式中，其他设备接收到一个第一类型的SCI且在第一时间门限内未接收到该该第一类型的SCI对应的第二类型的SCI，且在该第一类型的SCI的接收时刻之前接收到另一个第一类型的SCI，则表示与该第一类型的SCI对应的第二类型SCI已发送，确定第一类型的SCI所指示的时频资源是为发送端设备所预留的用于发送数据的时频资源。
第二类型的SCI所指示的时频资源是为接收端设备所预留的用于接收数据的时频资源。第二类型的SCI向其他设备指示在该时频资源发送数据会对该接收端设备产生干扰，而对其他设备能否在该时频资源上接收不做指示。
第三类型的SCI所指示的时频资源是为发送端设备所预留的用于发送数据的时频资源。第三类型的SCI向其他接收端设备指示在该时频资源上接收数据会受到该发送端设备干扰，而对其他设备能否在该时频资源上发送数据不做指示。第三类型的SCI与第一类型的SCI的区别至少包括：第一类型的SCI指示其对端的接收端设备发送第二类型的SCI；第三类型的SCI向其他设备指示其对端的接收端设备已经发送过第二类型的SCI，其他设备是除该发送端设备和对应的接收端设备外的设备。由于发送端设备只有在接收到其对端的接收端设备发送的第二类型的SCI之后才会发送第三类型的SCI，第二类型的SCI已对其他设备的发送行为进行指示，故第三类型的SCI对其他设备的发送行为不做指示。
因此，基于上述第一种可能的分类方式，采用图6和图7提供的实施例对本申请技术方案进行介绍说明；基于上述第二种可能的分类方式，采用图8和图9提供的实施例对本申请技术方案进行介绍说明。
图6是根据一示例性实施例示出的一种资源处理方法的流程图。该方法可应用于图3或图4或图5所示的网络架构中。该方法可以包括如下几个步骤。
步骤601，第二设备发送第一SCI，第一SCI的类型为第一类型，第一SCI包括第一指示信息，第一指示信息指示第一时频资源，第一指示信息还指示第一设备发送第二SCI，第二SCI的类型为第二类型。
其中，第一指示信息指示第一时频资源的时频位置。第一时频资源是为第二设备所预留的用于向第一设备发送数据的时频资源，或者，第一时频资源是为第二设备所预留的用于向第一设备发送数据、且为第一设备所预留的用于接收数据的时频资源。其中，第一设备是第二设备的对端设备。
在第一设备发送第二SCI之前，第一SCI向其他设备指示第一时频资源是为第二设备所预留的用于向第一设备发送数据、且为第一设备所预留的用于接收数据的时频资源，其他设备在第一时频资源上接收数据会受到第二设备干扰，在第一时频资源上发送数据可能会对第一设备的接收产生干扰；在第一设备发送第二SCI之后，第一SCI向其他设备指示第一时频资源是为第二设备所预留的用于向第一设备发送数据的时频资源，其他设备在第一时频资源上接收数据会受到第二设备干扰，但对其他设备的发送行为不做指示。
可选地，第一SCI还包括数据的第一业务优先级的指示信息、指示第一设备的设备标识的信息、指示第二设备的设备标识的信息。示意性地，数据为周期性业务数据， 预留的资源也是周期性的资源。

可选地，第一SCI还包括第一标识，第一标识指示第一设备发送第二SCI。
可选地，第一SCI还包括第二标识，第二标识指示第一SCI的类型为第一类型。
可选地，第一SCI可以利用NR R16版本中SCI的格式，并将其中第一阶SCI(SCI-1)中的2个预留的比特位用于第一标识和/或第二标识。可选地，其中一个预留的比特位为1时指示第一设备发送第二SCI，该比特位为0时指示第一设备不发送第二SCI；或者，该比特位为0时指示第一设备发送第二SCI，该比特位为1时指示第一设备不发送第二SCI。
其中另一个预留的比特位为1时指示该SCI的类型为第一类型，该比特位为0时指示该SCI的类型为第三类型；或者，该比特位为0时指示该SCI的类型为第一类型，该比特位为1时指示该SCI的类型为第三类型。
可选地，第一SCI和周期性业务数据一起发送。
步骤602，第一设备在接收到第一SCI后发送第二SCI，第二SCI包括第二指示信息，第二指示信息指示第二时频资源。
其中，第二指示信息指示第二时频资源的时频位置。第二时频资源是为第一设备所预留的用于接收数据的时频资源，第一时频资源可以包括第二时频资源。
其中第一设备发送第二SCI指示第二时频资源，从而向其他设备指示在第二时频资源上发送数据会对第一设备产生干扰,但对其他设备的接收行为不做指示。
第一设备接收到第二设备发送的第一SCI后，发送第二SCI。可选地，第一设备发送第二SCI的时频资源根据NR R16版本中的感知选择机制来确定。可选地，第二SCI还包括数据的第二业务优先级的指示信息和指示第二设备的设备标识的信息，第二业务优先级是根据第一业务优先级确定的。比如，第二业务优先级和第一业务优先级相同，又比如，根据预设映射关系，确定与第一业务优先级对应的第二业务优先级，预设映射关系包括预设的第一业务优先级与第二业务优先级之间的映射关系。
第一设备发送第二SCI之后，第二设备接收第二SCI，若第二设备在预定义的第一时间门限内没有收到第二SCI，则重复上述步骤，直至收到第二SCI。
步骤603，第二设备收到第二SCI后，发送第三SCI，第三SCI的类型为第三类型，第三SCI包括第三指示信息，第三指示信息指示第三时频资源，第三指示信息还向其他设备指示第一设备已经发送过第二SCI，其他设备为除了第一设备和第二设备外的设备。
第二设备接收到第二SCI后，将后续发送的SCI指示为第三SCI，以便通过第三SCI的第三指示信息向其他设备指示第一设备已经发过第二SCI，可无效化第一SCI的接收资源预留，即此时第一SCI所指示的第一时频资源仅是为第二设备所预留的用于向第一设备发送数据的时频资源，而不是为第一设备所预留的用于接收数据的时频资源。其中第三指示信息指示第三时频资源的时频位置。第三时频资源是为第二设备所预留的用于向第一设备发送数据的时频资源。
其中第二设备发送第三SCI指示第三时频资源，从而向其他接收端设备指示在第 三时频资源上接收数据会受到第二设备干扰。
可选地，第三SCI还包括数据的第一业务优先级的指示信息、指示第一设备的设备标识的信息、指示第二设备的设备标识的信息。

可选地，第三SCI可以利用NR R16版本中SCI的格式，并将其中第一阶SCI(SCI-1)中的2个预留的比特位用于第一标识和/或第二标识，相关指示方式可类比参考上述步骤601中第一SCI中的相关描述，在此不再赘述。
可选地，第三SCI和周期性业务的数据一起发送。
步骤604，第一设备发送第四SCI，第四SCI的类型为第二类型，第四SCI包括第四指示信息，第四指示信息指示第四时频资源。
其中，第四指示信息指示第四时频资源的时频位置。第四时频资源是为第一设备所预留的用于接收数据的时频资源。
第一设备发送第四SCI指示第四时频资源，从而向其他设备指示可以在第四时频资源上发送数据会对第一设备产生干扰。
可选地，第一设备接收到第二设备发送的第三SCI后，发送第四SCI。第三时频资源包括第四时频资源。
可选地，第四SCI还包括数据的第二业务优先级的指示信息和指示第二设备的设备标识的信息。
可选地，第二设备接收第一设备发送的第四SCI。
可选地，若第二设备的数据的业务特性维持不变(比如业务周期未改变或者业务尚未结束)，则重复执行步骤603和步骤604，即第二设备在发送周期性业务的数据时发送第三SCI为自身的发送行为进行资源预留，第一设备发送第四SCI为自身的接收行为进行资源预留，降低了数据传输过程中侧行链路干扰和冲突情况，提高了传输可靠性。当第二设备的数据的业务特性发生更改(比如业务周期改变或者业务结束)，第二设备重新执行步骤601，以满足更改后的业务特性的需求。本申请实施例对此不加以限定。
综上所述，在本申请实施例提供的资源处理方法中，第一SCI所包括第一指示信息指示第一时频资源，第一时频资源是为第二设备所预留的用于向第一设备发送数据的时频资源，或者指示为第二设备所预留的用于向第一设备发送数据、且为第一设备所预留的用于接收数据的时频资源，在第一设备发送第二SCI之前，第一SCI向其他设备指示第一时频资源是为第二设备所预留的用于向第一设备发送数据、且为第一设备所预留的用于接收数据的时频资源，其他设备在第一时频资源上接收数据会受到第二设备干扰，在第一时频资源上发送数据可能会对第一设备的接收产生干扰；在第一设备发送第二SCI之后，第一SCI向其他设备指示第一时频资源是为第二设备所预留的用于向第一设备发送数据的时频资源，其他设备在第一时频资源上接收数据会受到第二设备干扰，但对其他设备的发送行为不再做指示。第二SCI所包括第二指示信息指示第二时频资源，第二时频资源是为第一设备所预留的用来接收数据的时频资源，从而向其他设备指示在第二时频资源上发送数据会对第一设备产生干扰。收发两端共 同发送SCI进行资源预留，避免了其他设备对第一设备造成较大干扰，解决了隐藏终端问题，降低了侧行链路干扰和冲突情况，提高了传输可靠性。同时收发两端对资源的预留对其他设备的接收行为和发送行为做了不同的指示，第一设备发送第二SCI仅为自己的接收行为进行资源预留，在第一设备发送第二SCI之前，第二设备发送的第一SCI为第一设备的接收行为和第二设备的发送行为进行资源预留，在第一设备发送第二SCI之后，第二设备发送第三SCI为自己的发送行为进行资源预留，同时向其他设备指示第一设备已经发过第二SCI，此时其他设备在没有收到第二SCI的情况(或第二SCI的接收功率小于某个阈值的情况)下可无效化第一SCI的接收资源预留，即此时第一SCI所指示的第一时频资源仅是为第二设备所预留的用于向第一设备发送数据的时频资源，而不是为第一设备所预留的用于接收数据的时频资源。使得收到第一SCI和第三SCI的其他设备可以在不对第一设备造成过大干扰的情况下和第二设备共用时频资源进行数据发送，避免了暴露终端问题，提高了侧行链路中的空间复用效率。
基于图6提供的实施例，该资源处理方法还可以包括如下几个步骤，如图7所示：
步骤701，第二设备确定窗口内的历史SCI的类型包括第一类型、第二类型和第三类型。
可选地，当第二设备需要向第一设备发送信息时，确定窗内的历史SCI，历史SCI为第二设备历史上收到的至少一个SCI。历史SCI的类型包括第一类型、第二类型和第三类型。
第一类型的SCI包括第五指示信息，第五指示信息指示第五时频资源，第五时频资源是为发送端设备所预留的用于发送数据的时频资源，或者，第五时频资源是为发送端设备所预留的用于发送数据且为接收端设备所预留的用于接收数据的时频资源。
第二类型的SCI包括第六指示信息，第六指示信息指示第六时频资源，第六时频资源是为接收端设备所预留的用于接收数据的时频资源。
第三类型的SCI包括第七指示信息，第七指示信息指示第七时频资源，第七时频资源是为发送端设备所预留的用于发送数据的时频资源。
步骤702，第二设备根据预配置的目标资源池、历史SCI和第一预定义规则确定用于发送信息的目标发送时频资源。
在一种可能的实现方式中，第一预定义规则包括：
若某个第一类型的SCI的接收功率大于第一功率门限值，且历史SCI中不存在任何一个满足第二预设条件的第三类型的SCI，则表示与该第一类型对应的第二类型SCI可能尚未发送，在该第一类型的SCI所指示的第五时频资源发送数据可能会对第一类型SCI指示的接收端设备产生干扰，所以将第五时频资源从目标发送时频资源中去除。因此，目标发送时频资源不包括第五时频资源，该第二预设条件用于确定与该第一类型的SCI所对应的第二类型的SCI是否已经发送，对应关系为第二类型的SCI为受第一类型的SCI指示后发送的。
若某个第二类型的SCI的接收功率大于第二功率门限值，且第二类型的SCI中不包括第二设备的设备标识，则表示在第二类型SCI所指示的第六时频资源发送数据会对第二类型SCI指示的接收端设备产生干扰，所以将第六时频资源从目标发送时频资 源中去除。因此，目标发送时频资源不包括第六时频资源。
需要说明的是，第一类型的SCI的相关介绍可类比参考图6所示的实施例中对第一SCI的相关描述，第二类型的SCI的相关介绍可类比参考图6所示的实施例中对第二SCI的相关描述，与一个第一类型的SCI所对应的一个第二类型的SCI为受该第一类型的SCI指示后发送的第二类型的SCI，该对应关系可类比参考图6所示的实施例中第一SCI和第二SCI之间的关系的相关描述，在此不再赘述。
可选地，第一功率门限值是预配置的，或者是根据第一类型的SCI包括的业务优先级的指示信息确定的。示意性的，第一功率门限值与第一类型的SCI包括的业务优先级负相关，即第一类型的SCI包括的业务优先级越高，第一功率门限值越小。
可选地，第二功率门限值是预配置的，或者是根据第二类型的SCI包括的业务优先级的指示信息确定的。示意性地，第二功率门限值与第二类型的SCI包括的业务优先级负相关，即第二类型的SCI包括的业务优先级越高，第二功率门限值越小。
可选地，第二预设条件为：该第一类型的SCI和一个第三类型的SCI具有相同的指示发送端设备标识的信息和指示接收端设备标识的信息，且第五时频资源包括第七时频资源。当该第二预设条件满足时，一个第三类型的SCI与该第一类型的SCI对应，对应关系为一个第三类型的SCI是同一发送端设备在发送完第一类型的SCI之后发送的一个第三类型SCI。
需要说明的是，第一类型的SCI的相关介绍可类比参考图6所示的实施例中对第一SCI的相关描述，第三类型的SCI的相关介绍可类比参考图6所示的实施例中对第三SCI的相关描述，与一个第一类型的SCI所对应的一个第三类型的SCI是同一发送端设备在发送完该第一类型的SCI之后发送的一个第三类型SCI，该对应关系可类比参考图6所示的实施例中第一SCI和第三SCI之间的关系的相关描述，在此不再赘述。
由于发送端设备只有在接收到与一个第一类型的SCI对应的一个第二类型的SCI后才会发送与其对应的第三类型的SCI，当上述第二预设条件满足时，说明接收端设备已经发送过对应的第二类型的SCI并自行为其用于接收数据的资源进行预留，所以此时该第一类型的SCI对第二设备的发送行为不做指示。
可选地，若目标发送时频资源占目标资源池的比重小于预定义的第一门限值，提高第一功率门限值和第二功率门限值，然后重新执行步骤702，以保证确定出的目标发送时频资源满足信息传输的需求。若目标发送时频资源占目标资源池的比重大于或者等于预定义的第一门限值，则执行步骤703。需要说明的是，本申请实施例对第一预定义规则的设置方式不加以限定。
步骤703，第二设备发送触发消息，该触发消息指示第一设备上报辅助信息。
第二设备向第一设备发送触发消息，该触发消息指示第一设备进行资源感知和选择并上报辅助信息，该辅助信息包括第一设备能够用于接收信息的目标接收时频资源。
步骤704，第一设备确定窗口内的历史SCI，历史SCI的类型包括第一类型和第三类型。
可选地，第一设备在接收到第二设备发送的触发消息后，开启第一设备处的资源感知进程以辅助第二设备进行后续的资源选择。第一设备开启资源感知进程后，确定窗口内的历史SCI，历史SCI为第一设备历史上收到的至少一个SCI。其中，历史SCI 的类型包括第一类型和第三类型。
步骤705，第一设备根据预配置的目标资源池、历史SCI和第二预定义规则，确定辅助信息，辅助信息包括第一设备能够用于接收信息的目标接收时频资源。
在一种可能的实现方式中，第二预定义规则包括：
若某个第一类型的SCI的接收功率大于第一功率门限值，且一个第一类型的SCI不包括第一设备的设备标识，则表示在第一类型的SCI所指示的第五时频资源接收数据会对在第一类型的SCI指示的发送端设备产生干扰，所以将第五时频资源从目标接收时频资源中去除。因此，目标接收时频资源不包括第五时频资源。
若某个第三类型的SCI的接收功率大于第三功率门限值，且一个第三类型的SCI不包括第一设备的设备标识，则表示在第三类型的SCI所指示的第七时频资源接收数据会对在第三类型的SCI指示的发送端设备产生干扰，所以将第七时频资源从目标接收时频资源中去除。因此，目标接收时频资源不包括第七时频资源。
可选地，第三功率门限值是预配置的，或者是根据第三类型的SCI包括的业务优先级的指示信息确定的。示意性地，第三功率门限值与第三类型的SCI包括的业务优先级负相关，即第三类型的SCI包括的业务优先级越高，第三功率门限值越小。
可选地，若目标接收时频资源占目标资源池总资源的比重小于预定义的第二门限值，提高第一功率门限值和第三功率门限值，然后重新执行步骤705，以保证确定出的目标接收时频资源满足信息传输的需求。若目标发送时频资源占目标资源池的比重大于或者等于预定义的第二门限值，则执行步骤706。
需要说明的是，本申请实施例对第二预定义规则的设置方式不加以限定。
步骤706，第一设备上报辅助信息，辅助信息包括第一设备能够用于接收信息的目标接收时频资源。
第一设备将确定出的辅助信息上报至第二设备，该辅助信息包括第一设备能够用于接收信息的目标接收时频资源。
步骤707，第二设备确定向第一设备发送信息所使用的目标时频资源。
第二设备接收到第一设备上报的辅助信息后，确定该辅助信息中包括目标接收时频资源，根据确定出的目标发送时频资源和目标接收时频资源，确定向第一设备发送信息所使用的目标时频资源。
可选地，目标接收时频资源和目标发送时频资源均包括目标时频资源，即目标时频资源为目标接收时频资源和目标发送时频资源的交集中的时频资源。
可选地，若目标时频资源占目标资源池总资源的比重小于预定义的第三门限值，提高第一功率门限值、第二功率门限值和第三功率门限值，然后重新执行步骤702至707，以保证确定出的目标时频资源满足信息传输的需求。若目标时频资源占目标资源池总资源的比重大于或者等于预定义的第三门限值，则在目标时频资源上发送信息。
需要说明的是，本申请实施例提供的步骤701至步骤705可以在上述步骤601之前执行，也可以在上述步骤604之后执行，还可以在执行上述步骤601至步骤604的过程中并列执行，本申请实施例对此不加以限定。
综上所述，本申请实施例中，第二设备根据预配置的目标资源池、历史SCI和第一预定义规则确定用于发送信息的目标发送时频资源，第一设备根据预配置的目标资 源池、历史SCI和第二预定义规则，确定辅助信息，并上报该辅助信息，辅助信息包括第一设备能够用于接收信息的目标接收时频资源；使得后续第二设备能够根据确定出的目标发送时频资源和目标接收时频资源，确定第二设备向第一设备发送信息所使用的目标时频资源，优化了新的资源感知和选择机制，提高了数据传输的可靠性和效率。
图8是根据另一示例性实施例示出的一种资源处理方法的流程图。该方法可应用于图3或图4或图5所示的网络架构中。该方法可以包括如下几个步骤。
步骤801，第二设备发送第一SCI，第一SCI的类型为第一类型，第一SCI包括第一指示信息，第一指示信息指示第一时频资源，第一指示信息还指示第一设备发送第二SCI，第二SCI的类型为第二类型。
其中，第一指示信息指示第一时频资源的时频位置。第一时频资源是为第二设备所预留的用于向第一设备发送数据的时频资源，或者，第一时频资源是为第二设备所预留的用于向第一设备发送数据、且为第一设备所预留的用于接收数据的时频资源。
在第一设备发送第二SCI之前，第一SCI向其他设备指示第一时频资源是为第二设备所预留的用于向第一设备发送数据、且为第一设备所预留的用于接收数据的时频资源，其他设备在第一时频资源上接收数据会受到第二设备干扰，在第一时频资源上发送数据可能会对第一设备的接收产生干扰；在第一设备发送第二SCI之后，第一SCI向其他设备指示第一时频资源是为第二设备所预留的用于向第一设备发送数据的时频资源，其他设备在第一时频资源上接收数据会受到第二设备干扰，但对其他设备的发送行为不做指示。
可选地，第一SCI还包括数据的第一业务优先级的指示信息、指示第一设备的设备标识的信息、指示第二设备的设备标识的信息。示意性的，数据为周期性业务数据。
第一设备的设备标识用于在多个设备中唯一标识该第一设备，第二设备的设备标识用于在多个设备中唯一标识该第二设备。
可选地，第一SCI还包括第一标识，第一标识指示第一设备发送第二SCI。
可选地，第一SCI可以利用NR R16版本中SCI的格式，并将其中第一阶SCI(SCI-1)中的1个预留的比特位用于第一标识。可选地，预留的比特位为1时指示第一设备发送第二SCI，该比特位为0时指示第一设备不发送第二SCI，或者，该比特位为0时指示第一设备发送第二SCI，该比特位为1时指示第一设备不发送第二SCI。
可选地，第一SCI和周期性业务数据一起发送。
步骤802，第一设备在接收到第一SCI后发送第二SCI，第二SCI包括第二指示信息，第二指示信息指示第二时频资源。
第一设备在接收到第二设备发送的第一SCI后，发送第二SCI。
其中，第二指示信息指示第二时频资源的时频位置。第二时频资源是为第一设备所预留的用于接收数据的时频资源，第一时频资源包括第二时频资源。
其中第一设备发送第二SCI指示第二时频资源，从而向其他设备指示在第二时频资源上发送数据会对第一设备产生干扰。
第一设备接收到第二设备发送的第一SCI后，发送第二SCI。可选地，第一设备 发送第二SCI的时频资源可以根据NR R16版本中的感知选择机制来确定。
可选地，第一设备在接收到第一SCI后，需要在第一时间门限内发送第二SCI，即第二SCI的发送时刻与第一SCI的接收时刻的差值绝对值需要小于第一时间门限，第一时间门限可以是网络默认配置的。第一时间门限还可以是通过高层信令预配置的。本申请实施例对此不加以限定。
可选地，第二SCI还包括数据的第二业务优先级的指示信息和指示第二设备的设备标识的信息，第二业务优先级是根据第一业务优先级确定的。
可选地，若第二设备的数据的业务特性维持不变(比如业务周期未改变或者业务尚未结束)，则重复执行步骤801和步骤802，即第二设备在发送周期性业务的数据时发送第一SCI为自身的发送行为进行资源预留，第一设备在接收到第一SCI后发送第二SCI为自身的接收行为进行资源预留，降低了数据传输过程中侧行链路干扰和冲突情况，提高了传输可靠性。当第二设备的数据的业务特性发生更改，重新执行步骤801，以满足更改后的业务特性的需求。本申请实施例对此不加以限定。
综上所述，在本申请实施例提供的资源处理方法中，第一SCI所包括第一指示信息指示第一时频资源，第一时频资源是为第二设备所预留的用于向第一设备发送数据的时频资源，或者指示为第二设备所预留的用于向第一设备发送数据、且为第一设备所预留的用于接收数据的时频资源，在第一设备发送第二SCI之前，第一SCI向其他设备指示第一时频资源是为第二设备所预留的用于向第一设备发送数据、且为第一设备所预留的用于接收数据的时频资源，其他设备在第一时频资源上接收数据会受到第二设备干扰，在第一时频资源上发送数据可能会对第一设备的接收产生干扰；在第一设备发送第二SCI之后，第一SCI向其他设备指示第一时频资源是为第二设备所预留的用于向第一设备发送数据的时频资源，其他设备在第一时频资源上接收数据会受到第二设备干扰，但对其他设备的发送行为不做指示。第二SCI所包括第二指示信息指示第二时频资源，第二时频资源是为第一设备所预留的用来接收数据的时频资源，从而向其他设备指示在第二时频资源上发送数据会对第一设备产生干扰。收发两端共同发送SCI进行资源预留，避免了其他设备对第一设备造成较大干扰，解决了隐藏终端问题，降低了侧行链路干扰和冲突情况，提高了传输可靠性。同时收发两端对资源的预留对其他设备的接收行为和发送行为做了不同的指示，第一设备发送第二SCI仅为自己的接收行为进行资源预留，在第一设备发送第二SCI之前，第二设备发送的第一SCI为第一设备的接收行为和第二设备的发送行为进行资源预留；在第一设备发送第二SCI之后，第二设备在发送周期性业务的数据时发送第一类型的SCI为自己的发送行为进行资源预留，由于第一设备在收到第一SCI之后的第一时间门限内必须发送第二SCI，其他设备如果检测到两个对应的第一类型的SCI的间隔大于第一时间门限，就能知道第一设备已经发过第二SCI，此时其他设备在没有收到第二SCI的情况(或第二SCI的接收功率小于某个阈值的情况)下，则可无效化所有第一类型的SCI的接收资源预留，即此时第一类型的SCI所指示的时频资源仅是为发送端设备所预留的用于发送数据的时频资源，而不是为其对端的接收端设备所预留的用于接收数据的时频资源。使得收到第一SCI的其他设备在不对第一设备造成过大干扰的情况下可以和第二设备共用时频资源进行数据发送，避免了暴露终端问题，提高了侧行链路中的空间 复用效率。
基于图8提供的实施例，该资源处理方法还可以包括如下几个步骤，如图9所示：
步骤901，第二设备确定窗口内的历史SCI，历史SCI的类型包括第一类型和第二类型。
可选地，当第二设备需要向第一设备发送信息时，确定窗内的历史SCI，历史SCI为第二设备历史上收到的至少一个SCI。历史SCI的类型包括第一类型和第二类型。
其中，第一类型的SCI包括第五指示信息，第五指示信息指示第五时频资源，第五时频资源是为发送端设备所预留的用于发送数据的时频资源，或者，第五时频资源是为发送端设备所预留的用于发送数据且为接收端设备所预留的用于接收数据的时频资源；第二类型的SCI包括第六指示信息，第六指示信息指示第六时频资源，第六时频资源是为接收端设备所预留的用于接收数据的时频资源。
步骤902，第二设备根据预配置的目标资源池、历史SCI和第一预定义规则确定可用于发送信息的目标发送时频资源。
在一种可能的实现方式中，第一预定义规则包括：
若某个第一类型的SCI的接收功率大于第一功率门限值，且第一类型的SCI的接收时刻与当前时刻的差值绝对值小于第一时间门限，且历史SCI中不存在任何一个其他第一类型的SCI满足第一预设条件，则表示与该第一类型对应的第二类型SCI可能尚未发送，在该第一类型的SCI所指示的第五时频资源发送数据可能会对第一类型SCI指示的接收端设备产生干扰，所以将第五时频资源从目标发送时频资源中去除。因此，目标发送时频资源不包括第五时频资源。
若某个第二类型的SCI的接收功率大于第二功率门限值，且第二类型的SCI中不包括第二设备的设备标识，则表示在该第二类型SCI所指示的第六时频资源发送数据会对第二类型SCI指示的接收端设备产生干扰，所以将第六时频资源从目标发送时频资源中去除。因此，目标发送时频资源不包括第六时频资源。
由于在图8提供的实施例中，接收到一个第一类型的SCI后，接收端设备必须在第一时间门限内发送一个第二类型的SCI，所以当第一类型的SCI的接收时刻与当前时刻的差值绝对值大于第一时间门限，接收端设备已经发送过第二类型的SCI对其接收资源进行预留，故该情况下第一类型的SCI对第二设备的发送不做指示；该第一预设条件该用于确定在该第一类型的SCI之前，与其对应的第二类型的SCI是否已经发送，对应关系可参考步骤702中的对应关系，此处不再赘述。
可选地，第一功率门限值是预配置的，或者是根据第一类型的SCI包括的业务优先级的指示信息确定的。示意性的，第一功率门限值与第一类型的SCI包括的业务优先级呈相关关系，即第一类型的SCI包括的业务优先级越高，第一功率门限值越小。
可选地，第二功率门限值是预配置的，或者是根据第二类型的SCI包括的业务优先级的指示信息确定的。示意性的，第二功率门限值与第二类型的SCI包括的业务优先级呈相关关系，即第二类型的SCI包括的业务优先级越高，第二功率门限值越小。
可选地，第一预设条件为：其他第一类型的SCI和该第一类型的SCI具有相同的 指示发送端设备标识的信息、指示接收端设备标识的信息以及指示业务优先级的信息，且其他第一类型的SCI指示的时频资源包含该第一类型的SCI指示的时频资源，且该第一类型的SCI的接收时刻与其他第一类型的SCI的接收时刻大于第一时间门限。当该第一预设条件满足时，两个第一类型的SCI是同一个发送端设备给接收端设备发送的，且为同一业务预留资源。由于在图8所示的实施例中，接收到一个第一类型的SCI后，接收端设备必须在第一时间门限内发送一个第二类型的SCI，如果两个第一类型的SCI接收时刻大于第一时间门限，则表示接收端设备已经发送过第二类型的SCI对其接收资源进行预留，故该情况下该第一类型的SCI对第二设备的发送不做指示
可选地，若目标发送时频资源占目标资源池总资源的比重小于预定义的第一门限值，提高第一功率门限值和第二功率门限值，然后重新执行步骤902，以保证确定出的目标发送时频资源满足信息传输的需求。若目标发送时频资源占目标资源池总资源的比重大于或者等于预定义的第一门限值，则执行步骤903。
步骤903，第二设备发送触发消息，触发消息指示第一设备上报辅助信息。
步骤904，第一设备确定窗口内的历史SCI，历史SCI的类型包括第一类型。
步骤905，第一设备根据预配置的目标资源池、历史SCI和第二预定义规则，确定辅助信息，辅助信息包括第一设备能够用于接收信息的目标接收时频资源。
可选地，第二预定义规则包括：若某个第一类型的SCI的接收功率大于第一功率门限值，且第一类型的SCI不包括第一设备的设备标识，则表示在第一类型的SCI所指示的第五时频资源接收数据会对在第一类型的SCI指示的发送端设备产生干扰，所以将第五时频资源从目标接收时频资源中去除。因此，目标接收时频资源不包括第五时频资源。
可选地，第一功率门限值是根据第一类型的SCI包括的业务优先级的指示信息确定的。
可选地，若目标接收时频资源占目标资源池总资源的比重小于预定义的第二门限值，提高第一功率门限值，然后重新执行步骤905，以保证确定出的目标接收时频资源满足信息传输的需求。若目标发送时频资源占目标资源池总资源的比重大于或者等于预定义的第二门限值，则执行步骤906。
步骤906，第一设备上报辅助信息，辅助信息包括第一设备能够用于接收信息的目标接收时频资源。
步骤907，第二设备确定第二设备向第一设备发送信息所使用的目标时频资源。
可选地，若目标时频资源占目标资源池总资源的比重小于预定义的第三门限值，提高第一功率门限值、第二功率门限值和第三功率门限值，然后重新执行步骤902至907，以保证确定出的目标时频资源满足信息传输的需求。若目标时频资源占目标资源池总资源的比重大于或者等于预定义的第三门限值，则在目标时频资源上发送信息。
需要说明的是，本实施例中的各个步骤的相关细节可类比参考上述实施例中的相关描述，在此不再赘述。
综上所述，本申请实施例还通过对于感知无线资源的设备来说无需区分SCI的类型是第一类型还是第三类型，降低了设备的检测开销，提高了资源感知和选择的效率。
