为使本领域技术人员更好地理解本申请的技术方案，下面结合附图和实施例对本申请作进一步详细描述。应当理解的是，此处描述的具体实施例和附图仅仅用于解释本申请，而并非对本申请的限定。
图1为本申请实施例提供的应用场景示意图。请参见图1，包括终端设备101、终端设备102以及网络设备103。
其中，终端设备也可以称为用户设备(User Equipment，UE)、接入终端、用户单元、用户站、移动站、移动台、远方站、远程终端、移动设备、用户终端、终端、无线通信设 备、用户代理或用户装置等。终端设备101具体可以是一种向用户提供语音/数据连通性的设备，例如，具有无线连接功能的手持式设备、车载设备等。具体可以为：手机(Mobile Phone)、平板电脑(Pad)、带无线收发功能的电脑(如笔记本电脑、掌上电脑等)、移动互联网设备(Mobile Internet Device，MID)、虚拟现实(Virtual Reality，VR)设备、增强现实(Augmented Reality，AR)设备、工业控制(Industrial Control)中的无线终端、无人驾驶(Self Driving)中的无线终端、远程医疗(Remote Medical)中的无线终端、智能电网(Smart Grid)中的无线终端、运输安全(Transportation Safety)中的无线终端、智慧城市(Smart City)中的无线终端、智慧家庭(Smart Home)中的无线终端、蜂窝电话、无绳电话、会话启动协议(Session Initiation Protocol，SIP)电话、无线本地环路(Wireless Local Loop，WLL)站、个人数字助理(Personal Digital Assistant，PDA)、具有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、车载设备、可穿戴设备，第五代移动通信技术5G网络中的终端设备或者未来演进的公用陆地移动通信网络(Public Land Mobile Network，PLMN)中的终端设备等。
其中，可穿戴设备也可以称为穿戴式智能设备，是应用穿戴式技术对日常穿戴进行智能化设计、开发出可以穿戴的设备的总称，如眼镜、手套、手表、服饰及鞋等。可穿戴设备即直接穿在身上，或是整合到用户的衣服或配件的一种便携式设备。可穿戴设备不仅仅是一种硬件设备，更是通过软件支持以及数据交互、云端交互来实现强大的功能。广义穿戴式智能设备包括功能全、尺寸大、可不依赖智能手机实现完整或者部分的功能，例如：智能手表或智能眼镜等，以及只专注于某一类应用功能，需要和其它设备如智能手机配合使用，如各类进行体征监测的智能手环、智能首饰等。
此外，终端设备还可以是物联网(Internet of things，IoT)系统中的终端设备。IoT是未来信息技术发展的重要组成部分，其主要技术特点是将物品通过通信技术与网络连接，从而实现人机互连，物物互连的智能化网络。IoT技术可以通过例如窄带(Narrow Band)NB技术，做到海量连接，深度覆盖，终端省电。
此外，终端设备还可以包括智能打印机、火车探测器、加油站等传感器，主要功能包括收集数据(部分终端设备)、接收网络设备的控制信息与下行数据，并发送电磁波，向网络设备传输上行数据。本申请实施例对于终端设备的具体种类或者名称不作限定。
网络设备可以是任意一种具有无线收发功能的设备。该设备包括但不限于：演进型节点B(evolved Node B，eNB)、无线网络控制器(Radio Network Controller，RNC)、节点B(Node B，NB)、基站控制器(Base Station Controller，BSC)、基站收发台(Base Transceiver Station，BTS)、家庭基站(例如，Home Evolved NodeB，或Home Node B， HNB)、基带单元(Baseband Unit，BBU)，无线保真(Wireless Fidelity，WiFi)系统中的接入点(Access Point，AP)、无线中继节点、无线回传节点、传输点(Transmission Point，TP)或者发送接收点(Transmission and Reception Point，TRP)等。还可以为5G，如，新空口(New Radio，NR)系统中的gNB，或，传输点(TRP或TP)，5G系统中的基站的一个或一组(包括多个天线面板)天线面板，或者，还可以为构成gNB或传输点的网络节点，如基带单元(BBU)，或，分布式单元(Distributed Unit，DU)等。
在一些部署中，gNB可以包括集中式单元(Centralized Unit，CU)和DU。gNB还可以包括有源天线单元(Active Antenna Unit，AAU)。CU实现gNB的部分功能，DU实现gNB的部分功能。比如，CU负责处理非实时协议和服务，实现无线资源控制(Radio Resource Control，RRC)，分组数据汇聚层协议(Packet Data Convergence Protocol，PDCP)层的功能。DU负责处理物理层协议和实时服务，实现无线链路控制(Radio Link Control，RLC)层、介质接入控制(Medium Access Control，MAC)层和物理(Physical，PHY)层的功能。AAU实现部分物理层处理功能、射频处理及有源天线的相关功能。由于RRC层的信息最终会变成PHY层的信息，或者，由PHY层的信息转变而来，因而，在这种架构下，高层信令，如RRC层信令，也可以认为是由DU发送的，或者，由DU+AAU发送的。可以理解的是，网络设备可以为包括CU节点、DU节点、AAU节点中一项或多项的设备。此外，可以将CU划分为接入网(Radio Access Network，RAN)中的网络设备，也可以将CU划分为核心网(Core Network，CN)中的网络设备。本申请实施例对于网络设备的具体种类或者名称也不做限定。

需要说明的是，在直通链路sidelink中，针对的是终端设备与终端设备之间的侧行传输过程。本申请中也主要是针对直通链路传输过程中的资源分配。以下对本申请所涉及的相关技术进行说明：
一、V2X自主资源感知的资源排除过程
在NR系统中，车联网车载通信技术(Vehicle to Everything，V2X)是一种物物通信的技术，也即基于直通链路的通信技术。在NR系统的SL传输中，资源分配方式分为两种模式(mode)。其中，mode1是基站调度的资源分配方式。mode2也可以称为NR Sidelink分布式资源分配，是终端设备通过自主感知获取资源的方式。
(1)、资源池
图2示出了一种资源池的示意图。如图2所示，在一个资源池中，时域最小的资源粒度为时隙(slot)，频域最小的资源粒度为子信道或者子信号或者子通道(sub-channel)，一个sub-channel包含m个资源块(Resource Block，RB)，该数值m是高层配置的。终端设备在进行资源选择的时候，可以根据数据包的大小，确定需要L个sub-channel进行传输。此时传输资源为资源池中的某个slot中连续的L个sub-channel。如图2中示出了L＝3的一个传输资源201(图2中黑色方块部分)。终端设备在每个传输资源上会同时传输物理侧行控制信道(Physical Sidelink Control Channel，PSCCH)和物理侧行共享信道(Physical Sidelink Share Channel，PSSCH)。其中，PSCCH承载侧行链路控制信息或者侧行链路控制信令(Sidelink Control information，SCI)，PSSCH承载要传输的侧行链路数据。侧行链路控制信息SCI中可以包括当前资源的时频域位置信息以及预留资源的时频域位置信息等信息。
在直通链路的mode2模式中，终端设备可以在资源选择窗内自主选择传输资源。具体的，终端设备可以通过资源感知窗内的感知结果排除资源选择窗内被占用的资源，然后在剩余候选资源中选择传输资源。在资源感知窗内，如果传输资源需要占用L个连续的sub-channel，那么资源选择窗内的任意一个时隙内的任意连续L个sub-channel是一个候选资源，记资源选择窗内的候选资源总数为Mtotal。
(2)资源排除过程
资源排除过程可以是指终端设备根据资源感知窗内的感知结果，排除资源选择窗内不可用的候选资源。具体资源排除过程如下：
其一、如果终端设备因为半双工而不能对某个时隙例如slot y进行感知，那么终端设备就不能获得slot y内其他终端设备的资源占用以及周期性资源预留情况，使得资源选择时可能发生资源碰撞。因为不知道slot y内其他终端设备的预留周期，所以为了避免任何碰撞，假设slot y内其他终端设备的预留周期遍历该资源池内配置的所有周期，确定预留的周期性资源是否落在资源选择窗内。如果落在资源选择窗内的slot z内，那么认为slot z内的所有候选资源都是被其他终端设备预留的资源，slot z内的所有候选资源均不可用。
其二、解码其他终端设备的侧行控制信息或者侧行控制信令(Sidelink control information，SCI)，获得其他终端设备的资源预留信息。若其他终端设备预留的资源在资源选择窗内，通过参考信号接收功率(Reference Signal Receiving Power，RSRP)进一步判断。如果测量的RSRP大于RSRP阈值，那么判断该候选资源为一个不可用的候选资源。其中，RSRP阈值根据但当前终端设备和被测量终端设备的优先级确定。
经过上述资源排除过程，统计资源选择窗内剩余的可用候选资源，如果剩余的候选资源数少于资源选择窗内候选资源总数的预设百分比数值X*Mtotal，那么RSRP阈值增加3dB重复上述资源排除过程。其中X的值是可配置的，具体可以是20％、35％或者50％等。这样，最终获得一个候选资源数不少于X*Mtotal的候选资源集合，物理层可以将这个候选资源集合上报给媒体访问控制(Media Access Control，MAC)层。
示例性地，图3示出了一种NR V2X资源排除的示意图。如图3所示，当前正在做资源感知的终端设备为UE4。UE4在时刻n有数据包到达，(n-T0，n-Tproc，0)为资源感知窗口，(n+T1，n+T2)为资源选择窗口。UE4在资源感知窗口内做资源排除最终确定候选资源集。具体如下：
首先资源选择窗内的所有资源组成一个原始资源候选集。UE做资源发送/接收的时隙无法做资源感知，UE4把无法做感知的时隙slot y，按自己的所有可能的资源预留周期往后推算，排除掉落在资源选择窗所在的时隙slot z1和slot z2的所有资源。然后UE4解码其他UE(UE1、UE2、UE3)的SCI，获得其他UE的资源预留信息，并做RSRP测量，若测量到RSRP高于RSRP阈值(threshold)就排除掉。如图3中所示出的，UE4测得UE1预留的资源RSRP高于RSRP阈值，UE2和UE3预留的资源RSRP低于RSRP阈值，因此UE4在候选资源集中排除掉UE1预留的资源，最后候选资源集中剩余的资源即为最后的候选资源。
二、NR V2X资源预留周期
NR V2X的资源预留周期可能取值为{0，…，99，100，200，300，400，500，600，700，800，900，1000}，单位为毫秒。每个资源池配置的具体取值可以为上述集合中的16个，对应的无线资源控制(Radio Resource Control，RRC)参数为sl-ResourceReservePeriodList-r16。
三、LBT机制
由于授权频段的稀缺，在通信技术中往往可以通过非授权频段载波辅助授权频段载波通信，一定程度上可以增加可用带宽、提高频谱利用率及数据传输速率。在非授权频段中，“先听后说”LBT机制具体可以是指终端设备在开始传输之前首先会侦听其他设备的信道占用情况，检测信道是否空闲，若信道处于繁忙状态则等待信道空闲时再传输，避免信道接入冲突。
在NR非授权频段(New Radio in Unlicensed Spectrum，NR-U)系统中，若基站或者UE确定了信道占用时间COT，终端或者基站在信道接入成功后可在一段时间内使用此信道。在COT内的两次传输如果时间间隔小于16μs，则传输前不需要进行LBT；若大于16 微秒(μs)，在传输前则需要重新进行LBT，若LBT失败会使得此COT终止，导致数据传输中断。因此，在直通链路非授权频段接入(Sidelink-Unlicensed，SL-U)系统中，为保证COT不提前终止，需要COT内的传输在时域上尽可能连续。对于mode2即分布式资源分配方式，要求在资源选择时选择时间上连续的传输资源，使得终端设备的数据传输具备连续性。
但在相关技术中，NR V2X mode2的资源选择过程并不考虑时间上是否连续，无法保证数据的传输连续性，导致数据传输的可靠性不高。
在本申请实施例中，终端设备确定目标候选资源集合；目标候选资源集合包括至少一个预配置候选资源；每个预配置候选资源在时域上包括连续的第一数量个时隙，在频域上每个时隙包括连续的第二数量个子信道。这样，通过将时域上连续的第一数量个时隙、频域上每个时隙包括连续的第二数量个子信道，整体作为一个预配置候选资源，后续终端设备针对该预配置候选资源整体进行资源排除，能够确保传输资源在时域上的连续性，提高数据传输的可靠性。
以下通过具体实施例对本申请所示的方案进行详细说明。需要说明的是，以下几个实施例可以独立存在，也可以相互结合，对于相同或相似的内容，在不同的实施例中不再重复说明。
下面，结合图4所示的实施例，对资源分配的过程进行说明。
图4为本申请实施例提供的一种资源分配方法的流程示意图。请参见图4，该资源分配方法可以包括：
S401、确定目标候选资源集合；目标候选资源集合包括至少一个预配置候选资源；每个预配置候选资源在时域上包括连续的第一数量个时隙，在频域上每个时隙包括连续的第二数量个子信道。
本申请实施例中，目标候选资源集合可以是指资源选择窗内经过资源排除后剩余可用的候选资源的集合。在该目标候选资源集合中可以包括一个、两个或者多个预配置候选资源。其中，每个预配置候选资源在时域上包括连续的第一数量个时隙slot，在频域上每个时隙中包括第二数量个子信道sub-channel。预配置候选资源可以用R表示，第一数量可以用K表示，第二数量可以用L表示，当然也可以采用其他表示形式，本申请实施例对此不作限定。
具体的，在资源选择窗中，可以包括有多个预配置候选资源。终端设备在进行资源排除时，可以将预配置候选资源进行整体排除或者保留，这样，最终确定出的目标候选资源集合中包括至少一个预配置候选资源，预配置候选资源在时域上是连续的，保证了传输资 源在时域上的连续性，进而能够提高数据传输的可靠性。
需要说明的是，两个预配置候选资源在时域上所包括的连续时隙的第一数量可以是相同的，也可以是不同的；在一个预配置候选资源内，每个时隙内的连续子信道的第二数量可以是相同的，也可以是不同的，例如时隙1内可以有L1个连续的子信道，时隙2内可以有L2个连续的子信道等；并且，在一个预配置候选资源的不同时隙内第二数量个连续子信道的频域位置可能相同，也可能不相同，本申请实施例对此不作限定。
示例性地，图5为本申请实施例提供的一个预配置候选资源的示意图。在图5所示出的预配置候选资源中，在时域上包括连续的9个时隙slot，每个时隙上包括第二数量个连续的子信道sub-channel。各个时隙内的连续子信道的第二数量以及频域位置可以相同，也可以不相同。这样，图5中的所有黑色方块共同组成一个预配置候选资源，后续在进行资源排除时，该预配置候选资源要么整体排除，要么整体保留，这样可以确保选择的传输资源在时域上具备连续性。
本申请实施例中，终端设备确定目标候选资源集合；目标候选资源集合包括至少一个预配置候选资源；每个预配置候选资源在时域上包括连续的第一数量个时隙，在频域上每个时隙包括连续的第二数量个子信道。这样，通过将时域上连续的第一数量个时隙、频域上每个时隙包括连续的第二数量个子信道，作为一个预配置候选资源，后续终端设备针对该预配置候选资源整体进行资源排除，能够确保传输资源在时域上的连续性，提高数据传输的可靠性。
在一种可能的实施方式中，预配置候选资源根据预配置参数确定；预配置参数的数量为至少一组。
在一种可能的实施方式中，每组预配置参数包括优先级以及第二数量。
在一种可能的实施方式中，第一数量以及预配置参数通过MAC层指示。
本申请实施例中，预配置候选资源可以根据预配置参数确定，预配置参数的数量可以为一组、两组或者多组。每组预配置参数中，至少可以包括优先级(Priority)和第二数量L。其中，优先级具体可以是指PSSCH传输的优先级，后续可以用于计算RSRP阈值等，具体可以用P表示。优先级的高低可以用优先级值来表示，优先级值越小，优先级越高；优先级值越大，优先级越低。预配置参数中也可以包括其他参数，例如第一数量K等，本申请实施例对于每组预配置参数具体包括的参数种类不作限定。
本申请实施例中，第一数量K以及预配置参数可以由MAC层进行指示，当然也可以采用其他方式进行确定，本申请实施例对此亦不作限定。
在一种可能的实施方式中，当预配置参数的数量为至少两组时，预配置候选资源根据 目标配置参数确定；目标配置参数根据至少两组预配置参数确定。
在一种可能的实施方式中，目标配置参数为至少两组预配置参数中的其中一组；或者，
目标配置参数为至少两组预配置参数中优先级以及第二数量的重新组合。
本申请实施例中，当预配置参数的数量为两组或者两组以上时，可以从至少两组预配置参数中确定出一组预配置参数作为目标配置参数，用于划分并确定预配置候选资源。具体在确定目标配置参数时，可以是至少两组预配置参数中的其中一组，也可以是至少两组预配置参数内各个参数的重新组合。
示例性地，在从至少两组预配置参数中确定出一组作为目标配置参数时，终端设备可以选取优先级最高(优先级值最小)的预配置参数作为目标配置参数，或者终端设备可以选取优先级最低(优先级值最大)并且第二数量最大的预配置参数作为目标配置参数。在将至少两组预配置参数内各个参数进行重新组合得到目标配置参数时，终端设备可以在所有的优先级中选择最高的优先级，并且在所有的第二数量中选择最大的第二数量，将该最高的优先级以及该最大的第二数量组合形成目标配置参数。当然，在确定目标配置参数时，也可以采用其他方式，本申请实施例对此不作限定。
在一种可能的实施方式中，当预配置参数的数量为至少两组时，预配置候选资源根据至少两组预配置参数确定。
在一种可能的实施方式中，预配置候选资源中至少一个时隙对应一组预配置参数。
本申请实施例中，当预配置参数的数量为两组或者多组时，除了从其中选择一组来确定预配置候选资源，还可以直接根据至少两组预配置参数来确定预配置候选资源。这样，在预配置候选资源中，至少一个时隙对应一组预配置参数，能够提高预配置候选资源配置的灵活性。
示例性地，当预配置参数包括K组时，假设分别为(P1，L1)、(P2，L2)、(P3，L3)直至(PK，LK)。相应的，在预配置候选资源中，时隙1可以对应预配置参数(P1，L1)，时隙2可以对应预配置参数(P2，L2)，时隙3中可以对应预配置参数(P3，L3)，依次类推，时隙K可以对应预配置参数(PK，LK)。
可选的，预配置候选资源中第一数量个连续时隙对应的预配置参数分别为按优先级从高到低(优先级值从小到大)的预配置参数。即，在预配置候选资源中，时隙从前至后可以是按照优先级高低对应预配置参数。具体可以基于实际需求进行设置，本申请实施例对于连续时隙与预配置参数的具体对应关系不作限定。
在一种可能的实施方式中，在一个预配置候选资源中，若存在参考信号接收功率RSRP测量结果高于RSRP阈值，并且侧行控制信息SCI中预留指示的资源落在预配置候选资源 中，则目标候选资源集合中不包括预配置候选资源。
本申请实施例中，当前终端设备可获取其他终端设备的SCI，并解码各个其他终端设备的SCI，获取其他终端设备的资源预留信息；同时测量其他各个终端设备的参考信号接收功率RSRP。如果存在至少一个其他终端设备RSRP测量结果高于RSRP阈值并且SCI指示的预留资源落在预配置候选资源中，则该预配置候选资源不可用，该预配置候选资源被排除，目标候选资源集合不包括该预配置候选资源。如果不存在RSRP测量结果高于RSRP阈值并且SCI指示的预留资源落在预配置候选资源的其他终端设备，则该预配置候选资源可用，终端设备可以将该预配置候选资源添加至目标候选资源集合中。这样，通过对预配置候选资源进行整体排除或者保留，能够保证传输资源在时域上的连续性。
在一种可能的实施方式中，若资源选择窗内剩余的目标候选资源集合中候选资源的数量少于预设阈值，则目标候选资源集合通过增加RSRP阈值并重复进行资源排除的方式确定。
本申请实施例中，预设阈值可以是指资源选择窗内候选资源总数的预设百分比数值，具体可以为X*Mtotal，其中X可以为20％、35％或者50％等。当目标候选资源集合中候选资源的数量少于预设阈值时，终端设备可以增加RSRP阈值，例如每次增加3dB等，并重复进行基于RSRP测量值与RSRP阈值的资源排除，最终获得一个候选资源数不少于X*Mtotal的目标候选资源集合。
在一种可能的实施方式中，若RSRP阈值增加次数超过上限或者RSRP阈值超过上限，目标候选资源集合被上报至媒体接入控制MAC层或者目标候选资源集合通过终端设备进行选择后被上报至MAC层。
本申请实施例中，若RSRP阈值增加次数超过上限，即增加次数超过最大次数；或者RSRP阈值超过上限时，终端设备可以将目标候选资源集合上报至媒体接入控制MAC层进行资源选择。终端设备也可以对目标候选资源集合进行自主选择，在确保候选资源数量大于等于X*Mtotal的前提下，将自主选择后的目标候选资源集合上报至MAC层进行资源选择。
在一种可能的实施方式中，若RSRP阈值增加次数超过上限或者RSRP阈值超过上限，目标候选资源集合通过减小第一数量并重复进行资源排除的方式确定。
本申请实施例中，若RSRP阈值增加次数超过上限，即增加次数超过最大次数；或者RSRP阈值超过上限时，终端设备确定出的目标候选资源集合仍不满足大于等于X*Mtotal的条件，终端设备减小第一数量K，并继续上述资源排除过程，具体处理方式可以基于实际需求进行确定，本申请实施例对此不作限定。
在一种可能的实施方式中，资源分配方法应用于非授权频段的直通链路。
本申请实施例的资源分配方法可以应用于非授权频段的直通链路中，也可以应用于授权频段的直通链路中，还可以应用于终端设备与基站的上下行链路中，本申请实施例对于具体应用场景不作限定。
需要说明的是，预配置参数可以与传输块(Transport Block，TB)相对应。一组预配置参数可以对应一个或者多个TB，多组预配置参数可以对应多个TB等。
在本申请实施例中，为了尽量选择时域连续的传输资源，在资源排除时，需要考虑时域情况。在时间上连续性传输可以包括两种情况：一个TB的初传和重传在时间上连续，以及不同TB的初传或者重传在时间上连续。
示例性地，图6为本申请实施例提供的一个TB在时间上连续传输的示意图。如图6所示出的，在COT内，TB1的传输在时域上连续。此时可以对应根据一组预配置资源确定预配置候选资源的情况，终端设备可以基于TB1对应的预配置参数进行资源排除，来确定目标候选资源集合。这样，同一传输块的传输在时间上连续，可以确保COT不提前终止，确保数据传输的连续性。
示例性地，图7为本申请实施例提供的不同TB在时间上连续传输的示意图。如图7所示出的，在COT内，在连续的时隙内，依次分别传输TB1、TB2、TB3、TB1以及TB2。此时可以对应由至少两组预配置参数确定预配置候选资源池的情况，在时隙1内采用TB1对应的预配置参数进行资源排除，在时隙2内采用TB2对应的预配置参数进行资源排除，在时隙3内采用TB3对应的预配置参数进行资源排除，以此类推，最终确定出目标候选资源集合。这样，不同传输块的传输在时间上连续，可以确保COT不提前终止，确保数据传输的连续性。

确定模块11，用于确定目标候选资源集合；目标候选资源集合包括至少一个预配置候选资源；每个预配置候选资源在时域上包括连续的第一数量个时隙，在频域上每个时隙包括连续的第二数量个子信道。
