背景技术
新空口(New Radio，NR)副链路(SideLink，SL)的资源分配至少有模式(mode)1和mode 2两种模式。针对mode 1模式，控制节点会为终端分配传输资源，针对mode 2模式，终端进行自主选择传输资源。
在Mode 2资源分配模式中，资源抢占(Pre-emption)机制被支持。根据SL pre-emption操作，如果终端选择/预留的资源被其他终端抢占，那么需要重新进行资源选择，以使被抢占的终端在重选的资源上进行传输块(Transport Block，TB)传输，避免传输碰撞/干扰问题。然而，在现有技术中，如何判断终端选择/预留的资源是否被抢占，即如何对终端选择/预留的资源进行重评估，并没有解决方案。
发明内容
本申请实施例的目的是提供一种资源处理方法、资源处理装置及终端，能够实现对终端选择/预留的资源的重评估，解决因无法对终端选择/预留的资源进行重评估导致传输的可靠性较低的问题。

第四方面，提供了一种可读存储介质，所述可读存储介质上存储程序或指令，所述程序或指令被处理器执行时实现如第一方面所述的方法的步骤。
第五方面，提供了一种芯片，所述芯片包括处理器和通信接口，所述通信接口和所述处理器耦合，所述处理器用于运行网络侧设备程序或指令，实现如第一方面所述的方法。
在本申请实施例中，终端可以在第一时刻对目标资源进行重评估，所述目标资源包括以下至少一项：第二时刻对应的第一预留资源；第一资源预留信息指示的第二预留资源；第一资源预留信息指示的第三预留资源；其中，所述第一资源预留信息在所述第二时刻发送，所述第一时刻位于所述第二时刻之前；所述第二预留资源为非周期性资源，所述第三预留资源为周期性资源的资源周期内的资源。可见，本申请实施例能够实现对终端选择/预留的资 源的重评估，进而可以避免传输碰撞/干扰问题，提高传输的可靠性。

具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
本申请的说明书和权利要求书中的术语“第一”、“第二”等是用于区别类似的对象，而不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，以便本申请的实施例能够以除了在这里图示或描述的那些以外的顺序实施，且“第一”、“第二”所区别的对象通常为一类，并不限定对象的个数，例如第一对象可以是一个，也可以是多个。此外，说明书以及权利要求中“和/或”表示所连接对象的至少其中之一，字符“/”一般表示前后关联对象是一种“或”的关系。
值得指出的是，本申请实施例所描述的技术不限于长期演进型(Long Term Evolution，LTE)/LTE的演进(LTE-Advanced，LTE-A)系统，还可用于其他无线通信系统，诸如码分多址(Code Division Multiple Access，CDMA)、时分多址(Time Division Multiple Access，TDMA)、频分多址(Frequency Division Multiple Access，FDMA)、正交频分多址(Orthogonal Frequency Division Multiple Access，OFDMA)、单载波频分多址(Single-carrier Frequency-Division Multiple Access，SC-FDMA)和其他系统。本申请实施例中的术语“系 统”和“网络”常被可互换地使用，所描述的技术既可用于以上提及的系统和无线电技术，也可用于其他系统和无线电技术。然而，以下描述出于示例目的描述了新空口(New Radio，NR)系统，并且在以下大部分描述中使用NR术语，尽管这些技术也可应用于NR系统应用以外的应用，如第6代(6th Generation，6G)通信系统。
在本申请实施例中，终端也可以称作终端设备或者用户终端(User Equipment，UE)，终端可以是手机、平板电脑(Tablet Personal Computer)、膝上型电脑(Laptop Computer)或称为笔记本电脑、个人数字助理(Personal Digital Assistant，PDA)、掌上电脑、上网本、超级移动个人计算机(ultra-mobile personal computer，UMPC)、移动上网装置(Mobile Internet Device，MID)、可穿戴式设备(Wearable Device)或车载设备(VUE)、行人终端(PUE)等终端侧设备，可穿戴式设备包括：手环、耳机、眼镜等。需要说明的是，在本申请实施例并不限定终端的具体类型。
控制节点可以但不仅限于为以下任意一项：网络侧设备，中继UE(relay UE)，组头UE(Group header UE)等。所述网络侧设备可以是基站或核心网，其中，基站可被称为节点B、演进节点B、接入点、基收发机站(Base Transceiver Station，BTS)、无线电基站、无线电收发机、基本服务集(Basic Service Set，BSS)、扩展服务集(Extended Service Set，ESS)、B节点、演进型B节点(eNB)、家用B节点、家用演进型B节点、WLAN接入点、WiFi节点、发送接收点(Transmitting Receiving Point，TRP)或所述领域中其他某个合适的术语，只要达到相同的技术效果，所述基站不限于特定技术词汇。
为了方便理解，以下对本申请实施例涉及的一些内容进行说明：
一、副链路(SideLink，SL)资源抢占(Resource Pre-emption)。
NR Sidelink的资源分配至少有模式(mode)1和mode 2两种模式。针对mode 1模式，控制节点会为UE分配传输资源，针对mode 2模式，UE进行自主选择传输资源。
在Mode 2资源分配模式中，资源pre-emption机制被支持，该机制的简要描述如下：一个UE已经预留/选择的资源和其它具有更高优先级业务的UE所预留/选择的资源重叠(部分重叠)，如果该UE在相关资源上的SL参考信 号接收功率(Reference Signal Received Power，RSRP)测量值大于某个相关的SL-RSRP(associated SL-RSRP)门限值时，该UE会触发资源的重新选择。所述的业务优先级和所述的SL-RSRP门限由在所述资源上的传输块(Transport Block，TB)传输确定。
UE为了判断已经预留/选择的某资源是否被抢占，UE至少在m-T3时刻进行资源选择的重评估，m时刻是该资源所在的时刻或者用于指示该资源的资源预留信息发送的时刻，T3至少包括UE进行资源选择处理的时长。该资源可以为：物理副链路控制信道(Physical Sidelink Control Channel，PSCCH)或物理副链路分享信道(Physical Sidelink Shared Channel，PSSCH)资源等。
二、Sidelink的资源预留。
UE可以对其分配的资源进行资源预留(预留分为周期性预留和非周期性预留),预留资源为以后的PSCCH或PSSCH传输所用。
非周期预留可以通过副链路控制信息(Sidelink Control Information，SCI)中的时间资源分配(Time Resource Assignment)域实现，预留的资源至少可以用作同一个TB的传输。
周期预留可以通过SCI中的资源预留周期(Resource Reservation Period)域实现，当前周期预留的周期性资源至少可以用作下一个TB的传输。
下面结合附图，通过具体的实施例及其应用场景对本申请实施例提供的资源处理方法进行详细地说明。
参见图1，图1是本申请实施例提供的资源处理方法的流程图。本申请实施例的资源处理方法可以应用于终端。
如图1所示，资源处理方法可以包括以下步骤：

进一步地，所述第一时刻与所述第二时刻之间的间隔可以大于或等于资源重选的处理时长，这样，在所述重评估的评估结果为需要对所述目标资源进行资源重选，即所述目标资源被抢占的情况下，终端可以在所述第二时刻或在所述第二时刻之前进行资源重选，可以避免传输碰撞/干扰问题，从而可以提高传输的可靠性。当然，在其他实施方式中，所述第一时刻与所述第二时刻之间的间隔可以大于某个阈值，该阈值可以由协议约定、由控制节点配置或所述终端预配置，具体可根据实际需求设定，本申请实施例对此不做限定。
具体实现时，所述第二预留资源的预留可以通过时间资源分配(Time Resource Assignment)域实现；所述第三预留资源的预留可以通过资源预留周期(Resource Reservation Period)域实现。进一步地，所述第三预留资源可以包括周期性资源的下一个/多个资源周期内的部分或全部资源。需要说明的是，在本申请实施例中，下一个/多个资源周期可以理解为：当前资源周期的下一个/多个资源周期，当前资源周期可以为所述第一预留资源所在的资源周期。所述一个周期性资源可以由一个资源在时域上位移得到，所述位移的时域步长为一个资源周期的长度。所述周期性资源的一个资源周期内可以包括一个/多个周期性资源。
第二时刻对应的第一预留资源可以理解为：所述第二时刻为所述第一预留资源所在的时刻。可选的，所述第一预留资源属于周期性资源，所述第一预留资源可以为周期性资源的资源周期内的一个资源。
在实施时，对于所述第一资源预留信息指示的所述第二预留资源和所述第三预留资源：第一实现方式中，终端可仅对所述第二预留资源进行重评估；在第二实现方式中，终端可对所述第二预留资源和所述第三预留资源进行评估。

在本申请实施例中，终端在对所述目标资源进行重评估后，对于未被抢占的资源，终端可以在该资源上进行TB传输；对于被强占的资源，终端可以执行相应操作，以提高传输的可靠性，具体说明如下。
实施方式一、可选的，所述在第一时刻对目标资源进行重评估之后，所述方法还包括：
在所述重评估的评估结果为需要对所述第三预留资源进行资源重选的情况下，执行第一操作，所述第一操作包括以下任意一项：
重选第三预留资源所属的周期性资源；
重选第一副链路进程包括的全部周期性资源；
禁止在所述第一预留资源中预留所述第三预留资源；
释放第一副链路进程；
其中，所述第一副链路进程为所述第三预留资源所属的副链路进程。
在本实施方式中，所述第三预留资源被抢占，终端可以通过执行第一操作，可以避免传输碰撞/干扰问题，从而提高传输的可靠性。
在重选第三预留资源所属的周期性资源和重选第一副链路进程包括的全部周期性资源的场景中，终端进行资源重选，以在重选得到的重选资源上进 行TB传输，从而可以避免传输碰撞/干扰问题，提高传输的可靠性。
在禁止在所述第一预留资源中预留所述第三预留资源的场景中，资源预留周期(Resource Reservation Period)域可以置为0，这样，所述第一预留资源中不会预留所述第三预留资源，从而可以避免传输碰撞/干扰问题，提高传输的可靠性。
在释放第一副链路进程的场景中，由于所述第一副链路进程被释放，终端不会利用所述第三预留资源执行所述第一副链路进程，从而可以避免传输碰撞/干扰问题，提高传输的可靠性。
实施方式二、可选的，所述在第一时刻对目标资源进行重评估之后，所述方法还包括：
在所述重评估的评估结果为需要对所述第一预留资源进行资源重选的情况下，执行第二操作，所述第二操作包括以下任意一项：
释放所述第一预留资源；
释放所述第一预留资源所属的副链路进程。
在本实施方式中，所述第一预留资源被抢占，终端可以通过执行第二操作，可以避免传输碰撞/干扰问题，从而提高传输的可靠性。
在释放所述第一预留资源的场景中，终端不会在所述第一预留资源上进行TB传输，从而可以避免传输碰撞/干扰问题，提高传输的可靠性。
在释放所述第一预留资源所属的副链路进程的场景中，终端不会利用所述第一预留资源执行所述第一副链路进程，从而可以避免传输碰撞/干扰问题，提高传输的可靠性。
实施方式三、可选的，所述在第一时刻对目标资源进行重评估之后，所述方法还包括：
在所述重评估的评估结果为需要对所述目标资源进行资源重选的情况下，进行资源重选，得到第四预留资源；
根据第一规则，判断是否对所述第四预留资源进行周期性预留，所述第一规则包括以下至少一项：
1)所述终端决定是否对重选资源进行周期性预留；
2)根据第二条件判断是否对重选资源进行周期性预留，其中，在所述第 二条件满足的情况下，对重选资源进行周期性预留，所述第二条件满足包括以下至少一项：一个资源周期内的传输资源的资源个数小于或等于第二阈值，所述第二阈值为资源周期内允许的最大资源个数或一个TB允许传输的最大次数；信道繁忙比率(Channel Busy Ratio，CBR)小于第三阈值，所述第三阈值由协议约定或由控制节点配置或由所述终端预配置。具体的，所述一个资源周期内的传输资源的资源个数可以是下一个资源周期内的传输资源的资源个数。
可选的，上述资源周期内允许的最大资源个数、一个TB允许传输的最大次数可以是每个资源池(pool)或每个带宽部分(Bandwidth Part，BWP)限制的，即上述资源周期内允许的最大资源个数、一个TB允许传输的最大次数可以为每个pool或BWP的上述资源周期内允许的最大资源个数、一个TB允许传输的最大次数。
在本实施方式中，目标资源被抢占，终端进行资源重选，重选得到所述第四预留资源。本实施方式中的目标资源可以包括所述第一预留资源、所述第二预留资源和所述第三预留资源中的一项或多项。
在本实施方式中，终端在获取到重选资源，即所述第四预留资源后，可以根据第一规则判断是否对重选资源进行周期性预留。
在所述第一规则包括1)的场景中，终端可以自主决定是否对重选资源进行周期性预留。若终端决定对重选资源进行周期性预留，即允许周期性预留，则终端可以对所述第四预留资源进行周期性预留，否则对所述第四预留资源部进行周期性预留。
在所述第一规则包括2)的场景中，在第二条件满足的情况下，终端可以对所述第四预留资源进行周期性预留，否则对所述第四预留资源部进行周期性预留。
在实施时，若一个资源周期内的传输资源的资源个数小于或等于第二阈值，则终端可以对所述第四预留资源进行周期性预留，否则对所述第四预留资源部进行周期性预留。若CBR小于第三阈值，则终端可以对所述第四预留资源进行周期性预留，否则对所述第四预留资源部进行周期性预留。
需要说明的是，在某些实现方式中，若一个资源周期内的传输资源的资 源个数小于或等于第二阈值，或，CBR小于第三阈值，则终端可以对所述第四预留资源进行周期性预留。
通过上述方式，终端在进行资源重选后，可以对重选资源进行周期性预留，也可以不对重选资源进行周期性预留，从而可以提高资源重选的灵活度。
需要说明的是，本发明实施例中介绍的多种可选的实施方式，彼此可以相互结合实现，也可以单独实现，对此本发明实施例不作限定。
为方便理解，结合场景1和场景2示例说明如下：
场景1：UE在前一个资源周期判断下一个资源周期的预留资源是否被强占(即对下一个资源周期的预留资源进行重评估)，如图2a所示。
场景二：UE在某资源周期的预留资源没有相应的TB传输时，对该预留资源进行重评估，如图2b所示。
方案一：本方案针对场景1，说明对于周期性预留资源如何进行重评估。
1)对于某次TB传输，时刻m对应的传输资源(PSCCH/PSSCH资源)需要在‘m-T3’时刻进行资源选择的评估(评估后可以进行重选)，且在m时刻被预留的资源也要进行资源选择的评估(评估后可以进行重选)，所述预留资源包括以下至少一项：
只对非周期预留的资源进行评估；
对非周期和周期性预留的资源进行评估。
另外，是否对周期性预留的资源进行评估，可以取决于：预留周期小于某个阈值，阈值至少可以是定义/控制节点配置/预配置。
2)对于判断周期性预留资源进行资源选择评估(即，在当前周期判断后续周期的资源是否被抢占)。
所述周期性预留资源所传输TB的假设为：
TB的特性(或部分特性)与当前周期传输TB的特性(或部分特性)相同，例如TB在PSSCH/PSCCH上映射的priority，TB的PDB特性等；
TB的特性(或部分特性)为协议约定/配置/预配置的特性，例如TB在PSSCH/PSCCH上映射的priority为最大值/最小值/(预)配置的值，TB的PDB特性为固定的值(预)配置的值。
3)如果判断周期性预留资源需要资源重选，则执行以下至少一种行为
重选当前周期的相应资源；
当前周期不能预留所述需要资源重选的资源(即，SCI的周期预留域置0)；
释放需要资源重选的SL process。
方案二：本方案针对场景2，说明对于周期性预留资源如何进行重评估。
1)对于位于m时刻的传输资源(PSCCH/PSSCH资源)，在‘m-T3’时刻进行资源选择评估的条件(或，对评估后可以进行重选的条件)：
不晚于‘m-T3’的时刻，存在TB传输(即TB arrival不晚于m-T3时刻)。
2)如果在当前预留资源上无TB传输，UE也进行资源选择评估。
传输TB的假设为：
TB的特性(或部分特性)与前一次传输的TB的特性(或部分特性)相同，例如TB在PSSCH/PSCCH上映射的priority，TB的PDB特性等；
TB的特性(或部分特性)与该SL process上的前一次传输的TB的特性(或部分特性)相同，例如TB在PSSCH/PSCCH上映射的priority，TB的PDB特性等；
TB的特性(或部分特性)为协议约定/配置/预配置的特性，例如TB在PSSCH/PSCCH上映射的priority为最大值/最小值/(预)配置的值，TB的PDB特性为固定的值(预)配置的值
3)如果判断预留资源需要资源重选
释放当前需要重选资源；
释放需要资源重选的SL process。
方案三：本方案阐述重选的资源是否能够进行周期性预留，以解决资源过预留问题。
评估资源抢占时，如果根据重评估结果，对当前周期的传输资源(PSCCH/PSSCH资源)进行了资源重选。那么，按照以下方式判断重选的资源是否需要进行周期预留：
UE实现决定是否进行周期预留；即允许周期预留；
如果进行周期预留，下一个(/多个)的周期的资源个数不大于所允许的最大值/所允许一个TB传输个数的最大值(最大值可以是per pool/BWP限 制的)；否则不进行周期预留；
CBR小于某个threshold；否则不进行周期预留。其中，threshold为协议约定/配置/预配置的。
本申请实施例说明了对周期性预留资源如何进行重评估，以及阐述重选的资源进行周期性预留的行为限制，即阐述了周期性预留资源如何进行重评估的行为/条件，重选的资源进行周期性预留的方法。解决了UE不能判断/不能准确的判断所预留的资源是否真实被抢占的问题，以及资源过预留问题。
需要说明的是，本申请实施例提供的资源处理方法，执行主体可以为资源处理装置，或者，该资源处理装置中的用于执行资源处理的方法的控制模块。本申请实施例中以资源处理装置执行资源处理的方法为例，说明本申请实施例提供的资源处理的装置。
