Description

资源确定方法、装置、节点和存储介质 技术领域
本申请涉及通信技术领域，具体涉及一种资源确定方法、装置、节点和存储介质。
背景技术
非授权频谱属于共享频谱，终端需要以竞争机制的方式获得信道接入权，以使用频谱，那么当终端较多时，导致终端可能抢占不到信道，使得在非授权频谱上发送数据存在不确定性，或者终端可能延时抢占到信道，导致数据发送延迟。为了保证一些对时延要求较高的业务(例如，超高可靠与低时延通信(Ultra Reliable Low Latency Communications，URLLC))，减少调度的时间，基站可以采用预配置的方法，为终端分配固定的时频域。如图1所示，基站为终端分配一定周期、占用一定带宽的资源，当终端有上行数据到达时，可以直接利用配置的资源发送上行数据。但是，当采用非授权频谱传输时延要求较高的业务时，即使采用了预配置的方法，由于存在竞争机制，还是会存在增加业务时延的问题。
目前的解决方式是提高节点抢占信道的成功概率，如图2所示，基站预配置多个频域的资源，当有数据发送时，终端在多个频域上同时竞争，哪个频域上竞争成功，就在哪个频域上发送，但这样需要占用多个频谱资源，导致浪费频谱资源。

具体实施方式
为使本申请的目的、技术方案和优点更加清楚明白，下文中将结合附图对本申请的实施例进行详细说明。需要说明的是，在不冲突的情况下，本申请中的实施例及实施例中的特征可以相互任意组合。
另外，在本申请实施例中，“可选地”或者“示例性地”等词用于表示作例子、例证或说明。本申请实施例中被描述为“可选地”或者“示例性地”的任何实施例或设计方案不应被解释为比其它实施例或设计方案更优选或更具优势。确切而言，使用“可选地”或者“示例性地”等词旨在以具体方式呈现相关概念。
为了便于理解本申请实施例的方案，示例性地给出了部分与本申请相关概念的说明以供参考。如下所示：
非授权频谱：非授权频谱用于蜂窝网络的组网中，既可以作为授权频谱的辅助频谱进行组网，用于双链接的辅助节点(Secondary Node，SN)的频谱资源或者载波聚合的辅助小区频谱资源，也可以独立组网用于单独(standalone)小区的频谱资源。如图3所示，为利用非授权频谱进行4G/5G组网时的网络侧架构，节点(例如，基站)采用非授权频谱提供无线服务，并通过NG/SI接口连接核心网设备，节点之间通过Xn/X2接口连接。
先听后说(Listen Before Talk，LBT)机制：第三代合作伙伴计划(3rd Generation Partnership Project，3GPP)和欧洲电信标准协会(European Telecommunications Standards Institute，ETSI)标准组织制定了LBT机制。在发送数据之前，发送方需要监听信道是否空闲，如果空闲，发送方使用信道发送数据，否则需要继续监听直至信道空闲。例如，两个节点共享100MHz带宽，若节点需要发送数据，则需要在准备占用的带宽内进行竞争。如果两个节点同时准备在相同的带宽内发送数据，那么这两个节点就需要竞争，竞争成功的节点才可以发送数据。
竞争机制：ETSI和3GPP定义了多种竞争机制，CAT4/Type1是一种终端通 过产生随机数来决定监听信道的时长的竞争机制；CAT 2 25us/Type2A是一种终端在25us时长内监听信道的竞争机制，一般是在基站成功抢占到信道后，共享信道给终端以发送上行数据，并且保证上下行之间的空白为25us；CAT 2 16us/Type2B是一种终端在16us时长内监听信道的竞争机制，一般是在基站成功抢占到信道后，共享信道给终端发送上行数据，并且保证上下行之间的空白为16us；CAT 1/Type2C是一种终端不需要监听信道就立即发送数据的机制，一般是在基站成功抢占到信道后，共享信道给终端发送上行数据，并且保证上下行之间的空白小于等于16us。这些竞争机制需要监听信道的时长不同，按照时长从大到小排序，或者获取信道接入权从难到易排序的顺序是CAT4>CAT 2 25us>CAT 2 16us>CAT1。
本申请实施例可以应用于如下场景，在一段频域内，第二通信节点可以在多个子带(20M LBT带宽)配置、激活多个configured grant，CG#1，CG#2，CG#3。在时刻n，第一通信节点在CG#2所在的子带竞争失败，但是在CG#1、CG#3所在的子带竞争成功，即第一通信节点在时刻n，有CG#1，CG#3多个资源可用，这样存在资源占用浪费的问题。
基于上述概念和上述场景中存在的问题，图4为本申请实施例提供的一种资源确定方法的流程图，如图4所示，该方法可以包括：
S401、第一通信节点获取第二通信节点配置的配置信息。
示例性地，本申请实施例中的配置信息可以包括初传配置信息和/或重传配置信息。第二通信节点与第一通信节点可以为两种不同类型的通信节点。例如，第一通信节点可以为终端，第二通信节点可以为基站。
S402、第一通信节点根据配置信息在多个预配置资源中选择目标资源。
本步骤中，预配置资源为第二通信节点配置的时频域资源，例如，第二通信节点可以为第一通信节点配置多个配置授权configured grant，半持续性调度(Semi-Persistent Scheduling，SPS)。
第一通信节点获取到第二通信节点配置的配置信息后，可以根据该配置信 息在第二通信节点配置的多个预配置的时频资源中选择目标资源。这样，当第一通信节点有多个可用的频谱资源时，可以根据配置信息选择对应的目标时频域资源，从而保证第一通信节点上传输数据的可靠性。
在本申请实施例中，第二通信节点配置的初传配置信息可以包括以下多种信息中的任意一项：
第一种信息，指示是否使能第一通信节点选择目标资源。
示例性地，第二通信节点可以通过无线资源控制(Radio Resource Control，RRC)消息、物理地址控制单元(Media Access Control Control Element，MAC CE)或者下行控制信息(Down Control Information，DCI)指示是否使能第一通信节点选择目标资源。例如，RRC消息(如，RRC重配消息)中可以携带一个信元，该信元指示是否使能第一通信节点选择资源的功能；或者MAC CE或者DCI指示携带一个比特，该比特指示是否使能第一通信节点选择资源的功能，比如，1为使能，0为不使能。
第二种信息，使能第一通信节点选择目标资源，并选择干扰最小的频域资源。
若第二通信节点为第一通信节点配置有多个可用的时频域资源，第一通信节点只能选择其中一个资源发送数据。那么，第二通信节点可以配置第一通信节点在多个资源上进行测量，第一通信节点可以得到每个频域的干扰测量结果(例如，干扰强度、干扰频率或者抢占成功概率等)，第一通信节点根据每个频域上测量值选择一个干扰最小(例如，干扰强度值小、干扰频率值小或者抢占成功概率值大等)的资源，从而保障业务传输的时延以及可靠性。
进一步地，本申请实施例提供的具体示例可以为，第一通信节点在每个子带分别进行测量，并得到每个子带的干扰强度(接收信号的强度)和信道占用率(高于一定门限值的接收信号强度的百分比，体现干扰频率)。当某个子带的干扰强度小于对应门限值，和/或，信道占用率低于对应门限值，则第一通信节点确认该子带干扰较小，选择该子带上的资源；或者，当某个子带的干扰强度 小于对应门限值，和/或，信道占用率低于对应门限值，并且干扰强度值最小或信道占用率值最小，则第一通信节点确认该子带干扰较小，选择该子带上的资源。
第三种信息，基于竞争机制选择目标资源。
第二通信节点预配置了多个频域资源，例如，多个configured grantration，SPS配置。在某个时刻，当第一通信节点需要发送数据时，存在第二通信节点配置的多个频域资源，而且各资源对应的竞争类型不同，比如，第二通信节点在多个子带(20M LBT带宽)配置、激活多个configured grant，CG#1，CG#2，CG#3。如图5所示，在时刻n，第一通信节点在CG#1所在的子带进行Cat1的竞争，在CG#2所在的子带进行Cat4的竞争类型，在CG#3所在的子带进行Cat225us的竞争类型，在CG#4所在的子带需要进行Cat2 16us的竞争类型。而由于在各个竞争机制中，第一通信节点获取信道接入权的成功概率是Cat1≥Cat2 16us≥Cat2 25us≥Cat4，则第一通信节点可以选择获取信道接入权概率较高的configured grantration，也就是CG#1的资源。
这样，在第一通信节点同时有多个上行资源配置，而且每个资源对应的获取频域资源所需要执行的竞争机制不同的情况下，第一通信节点根据竞争机制选择资源，可以尽可能的保证第一通信节点获取信道接入权，并获得可用的目标资源，从而保证业务数据时延。
第四种信息，指示第一通信节点根据参数信息选择目标资源，其中，参数信息包括第一通信节点标识、小区标识、随机数、频带信息中的任意一种。
示例性地，假设初传配置信息为使能第一通信节点根据参数信息选择目标资源。那么在第一通信节点配置有多个预配置资源的情况下，第一通信节点根据第一通信节点标识选择频域资源的实现方式可以为，第一通信节点标识(可以为第二通信节点分配的节点标识或其他标识，如s-tmsi)与每个配置资源之间存在关联关系，该关联关系可以是将第一通信节点标识计算得到的值关联至配置资源。例如，三个第一通信节点共享CG#1，CG#2，CG#3，第一通信节点1 的标识为1，第一通信节点2的标识为2，第一通信节点3的标识为3，若第一通信节点标识mod 3＝0，则该第一通信节点选择CG#1；若第一通信节点标识mod 3＝1，则该第一通信节点选择CG#2；若第一通信节点标识mod 3＝2，则该第一通信节点选择CG#3。
第一通信节点根据小区标识选择目标资源的实现方式可以为，小区标识(例如，小区的物理小区标识或者全球统一标识或者其他小区级标识)与每个配置资源之间存在关联关系，该关联关系可以将小区标识计算得到的值关联至配置资源。例如，三个第一通信节点共享CG#1，CG#2，CG#3，第一通信节点1所在的小区1的标识为1，第一通信节点2所在的小区2的标识为2，第一通信节点3所在的小区3的标识为3，若小区标识mod 3＝0，则该小区的第一通信节点选择CG#1；若小区标识mod 3＝1，则该小区的第一通信节点选择CG#2；若小区标识mod 3＝2，则该小区的第一通信节点选择CG#3。
第一通信节点根据随机数选择目标资源的实现方式可以为，第一通信节点产生随机数，不同随机数关联至不同配置资源。例如，三个第一通信节点共享CG#1，CG#2，CG#3，每个第一通信节点产生1～3之间的随机整数，当第一通信节点产生的随机整数为1时，选择CG#1；当第一通信节点产生的随机整数为2时，选择CG#2；当第一通信节点产生的随机整数为3时，选择CG#3。
第一通信节点根据频带信息选择目标资源的实现方式可以为，第二通信节点通过系统信息或者RRC消息，通知第一通信节点频带的频带信息，如每个频带的竞争类型，竞争优先级,业务信息,资源类型、规避类型、预留资源等。第一通信节点根据这些频带信息，优选对应频带竞争机制用时短或者优先级高的频域资源，或者，次选对应频带竞争机制用时长或者优先级低的资源，或者，规避、静默或者放弃对应频带需要规避的资源。例如，第二通信节点在RRC消息(如，RRC重配消息)中携带一个信元，信元指示某个频带的竞争优先级低，某个频带的竞争优先级高，则第一通信节点可以优选竞争优先级高的频带上的资源。
通过上述几种不同的方式可以使第一通信节点选择对应的目标资源，可以减少各第一通信节点之间的竞争，从而保证第一通信节点上数据传输的时延和可靠性。
在一种示例中，第二通信节点配置的重传配置信息可以包括以下多种信息中的任意一项：
第一种信息，使能第一通信节点选择目标资源，并基于重传数据包传输块大小(Transport Block Size，TBS)选择干扰最小的目标资源。
若第一通信节点支持自动重传，则第一通信节点在有多个可用的频域资源的场景下，根据重传数据包TBS选择干扰最小的目标资源，例如，第一通信节点选择大于且最接近重传数据包TBS的频域资源，而后选择干扰最小的频域资源，以提高资源利用率。
第二种信息，根据定时器和重传数据包TBS选择用于重传的目标资源。
示例性地，假设第二通信节点为第一通信节点配置了多个预配置资源，每个预配置资源可以具有不同的时刻(周期，起始时刻等)，频域位置，传输块大小等。在某个时刻，若第一通信节点在该时刻的某个预配置资源上传输数据包，或者，根据该时刻的预配置资源的TBS产生数据包，同时第一通信节点启动定时器，若传输数据包失败，则需要重传该数据包。那么在定时器超时之前，第一通信节点可以选择与数据包TBS相同的预配置资源进行数据重传；在定时器超时之后，第一通信节点可以选择TBS大于等于重传数据包且时间最邻近的预配置资源进行数据重传。
例如，如图6所示，第一通信节点有多个预配置的资源，CG#1，CG#2，CG#3，且CG#1 TBS>CG#2 TBS＝CG#3 TBS。第一通信节点选择了在时刻a的CG#2，并产生了基于CG#2的TBS的数据包1，同时第一通信节点在时刻a启动一个定时器，但是在时刻a，第一通信节点竞争失败，需要重传数据包1。那么如果在定时器超时之前，第一通信节点没有找到与重传数据包TBS相同的预配置资源，如CG#1，CG#3。但是在定时器超时之后，时刻b，CG#1的资源最 邻近且CG#1 TBS>CG#2 TBS，则第一通信节点选择时刻b的CG1资源重传数据包1。
同样地，假设第一通信节点选择了在时刻d的CG#2，并产生了基于CG#2的TBS的数据包2，同时第一通信节点在时刻d启动一个定时器。但是在时刻d，第一通信节点竞争失败，需要重传数据包2。如果在定时器超时之前，第一通信节点找到与重传数据包TBS相同的预配置资源，如CG#3，则第一通信节点选择时刻d的CG3资源重传数据包。
需要说明的是，上述过程中的定时器的时长可以为第二通信节点为预配置资源配置的。
第三种信息，根据预配置资源属性选择用于重传的目标资源，预配置资源属性为抢占优先级或是否允许占用。
第二通信节点为不同的预配置资源配置不同的属性，例如，配置不同的抢占优先级。第二通信节点可以通过RRC信令或者DCI为每个预配置资源配置一个信元，该信元可以有几个比特，比特值标识预配置资源抢占优先级的高低，例如，11表示抢占优先级3，10表示抢占优先级为2等。那么第一通信节点在抢占优先级高的预配置资源上传输数据包时，如果发生重传，则可以占用抢占优先级相等或者预配置资源优先级低的资源进行重传。而第一通信节点在抢占优先级低的预配置资源上传输数据包时，如果发生重传，则第一通信节点不能占用抢占优先级高的预配置资源进行重传。
示例性地，假设第一通信节点有多个预配置资源，分别为CG#1，CG#2，CG#3，第二通信节点配置CG#1的抢占优先级为11，CG#2的抢占优先级为10，CG#3的抢占优先级为10。当第一通信节点在CG#1上传输数据包时，由于在CG#1上信道抢占不成功，数据包需要重传，那么第一通信节点可以选择在CG#1，CG#2和CG#3上的资源重传数据包。当第一通信节点在CG#2上传输数据包时，由于在CG#2上信道抢占不成功，数据包需要重传，那么第一通信节点可以选择在CG#2，CG#3上的资源重传数据包。
若第二通信节点为预配置资源配置的属性为是否允许占用，例如，第二通信节点通过RRC信令或者DCI为每个预配置资源配置一个信元，该信元可以有1个比特，1可以表示允许被占用，0可以表示不允许被占用。如果某预配置资源被配置为不允许占用，则该预配置资源不能被用来重传在其他预配置资源上未传输成功的数据包。如果某个预配置资源被配置为允许占用，则该预配置资源可以用来传输在其他预配置资源上未传输成功的数据包。
示例性地，假设第一通信节点有多个预配置资源，分别为CG#1，CG#2，CG#3，第二通信节点配置CG#1不允许被占用，CG#2配置为允许被占用，CG#3配置为允许被占用。那么第一通信节点在CG#1上传输数据包时，由于在CG#1上信道抢占不成功，数据包需要重传，则第一通信节点可以选择在CG#1，CG#2和CG#3的资源上重传数据包。若第一通信节点在CG#2上传输数据包，由于在CG#2上信道抢占不成功，数据包需要重传时，则第一通信节点可以选择在CG#2，CG#3的资源上重传数据包。
图7为本申请实施例提供的一种资源确定方法的流程图，如图7所示，该方法包括：
S701、第一通信节点在第一条件下监听第二通信节点发送的信令。
上述步骤中的第一通信节点可以为至少两个通信节点，该第一通信节点可以为终端，第二通信节点可以为基站，即第一通信节点与第二通信节点是两种不同类型的通信节点。那么本步骤可以为多个终端在第一条件下监听基站发送的信令。
示例性地，本步骤中的多个第一通信节点的预配置资源可以在相同的频域，以及相同或不相同的时域，如图8所示，第一通信节点1和第一通信节点2都在子带1。
S702、第一通信节点根据信令去激活指定资源，和/或，激活指定资源。
多个第一通信节点在第一条件下监听到第二通信节点的指令后，可以根据该信令去激活指定资源，和/或，激活指定资源。
例如，假设第一通信节点1和2都在子带1，WiFi节点占用子带1的频域持续一段时间发送数据，那么子带1上的所有通信节点(包括第一通信节点1和2)都可能会持续受到干扰。因此，可以通过一条去激活信令将某个子带的configured grant或者SPS去激活，或通过一条激活信令将某个子带的configured grant或者SPS激活。
这样可以在节约空口资源的情况下，通过一条信令将多个第一通信节点选择到其他频域(比如，干扰较小的频域)上，减少信令开销，降低信令时延，从而保证多个第一通信节点上传输的数据业务的可靠性和时延要求。
示例性地，在本申请实施例中，第二通信节点发送的信令可以为公共物理下行控制信道(Physical Downlink Control Channel，PDCCH)，该公共PDCCH中可以携带不同的信息，如下：
第一种，公共PDCCH携带激活的配置信息，和/或，去激活的配置信息。
多个第一通信节点监听公共PDCCH，该公共的PDCCH可以通知多个第一通信节点去激活某个频域上的资源，激活其他频域上的资源。其中，该频域上的资源可以是整个频域的资源，也可以是预配置资源。
例如，公共PDCCH可以携带指示激活的预配置索引，和/或，指示去激活的预配置索引，该公共PDCCH指示多个第一通信节点去激活某个频域上的预配置资源，激活其他频域上的预配置资源。多个第一通信节点成功监听到公共PDCCH后，可以根据指令，激活对应的预配置的资源。示例性地，假设多个第一通信节点成功监听公共PDCCH(Group Common-PDCCH，GC-PDCCH)，GC-PDCCH中可以携带激活的configured grant或者SPS索引，配置的激活configured grant或者SPS的调度信息(如频域位置，时间位置，调制与编码策略(Modulation and Coding Scheme，MCS)等)，和/或，配置的去激活信息，去激活的configured grant或者SPS索引。多个第一通信节点监听到该GC-PDCCH并解码成功后，可以根据指令，激活、去激活对应的configured grant或者SPS。
或者，公共PDCCH中可以携带指示激活的频域信息，和/或，指示去激活 的频域信息，该公共PDCCH指示多个第一通信节点去激活某个频域上的整个资源，激活其他频域上的整个资源。多个第一通信节点成功监听到公共PDCCH后，可以根据指令，激活对应的频域资源。示例性地，假设多个第一通信节点成功监听GC-PDCCH，GC-PDCCH中可以携带指示激活信息，激活的频域索引(如部分带宽(Bandwidth Part，BWP)索引)，和/或，配置的去激活信息，去激活的频域索引(如BWP索引)。多个第一通信节点监听到GC-PDCCH并解码成功后，可以根据指令，激活、去激活对应的频域(如BWP)，以及该频域上的configured grant或者SPS。
第二种，公共PDCCH携带用户标识、激活的预配置索引和/或去激活的预配置索引。
多个第一通信节点监听公共PDCCH，在多个第一通信节点的配置不相同的情况下，该公共的PDCCH可以针对每个第一通信节点进行相应的指令，以通知其去激活某个频域上的资源，激活其他频域上的资源。其中，该频域上的资源可以是整个频域的资源，也可以是预配置资源。
例如，公共PDCCH可以通知不同的第一通信节点去激活不同频域上的预配置资源，和/或，激活不同频域上的预配置资源。比如，该公共PDCCH指示各第一通信节点的激活预配置索引，和/或，去激活的预配置索引。各第一通信节点成功监听到公共PDCCH后，可以根据指令去激活，和/或，激活对应的预配置的资源。示例性地，假设多个第一通信节点监听GC-PDCCH，GC-PDCCH中携带第一通信节点标识，激活的configured grant或者SPS索引，配置的激活configured grant或者SPS的调度信息(如频域位置，时间位置，MCS等)，和/或，去激活信息和第一通信节点标识以及去激活的configured grant或者SPS索引。第一通信节点监听到GC-PDCCH并解码成功后，可以根据指令，激活、去激活对应的configured grant或者SPS。
或者，公共PDCCH通知不同第一通信节点去激活不同的频域上的整个资源，激活不同的其他频域上的整个资源。比如，公共PDCCH可以指示各第一通信节 点激活的频域信息，和/或，各第一通信节点去激活的频域信息。各第一通信节点成功监听到公共PDCCH后，可以根据指令，激活对应的频域资源。示例性地，假设多个第一通信节点监听GC-PDCCH，GC-PDCCH中携带第一通信节点标识，各第一通信节点标识对应的激活信息，以及激活的频域索引(如BWP索引)，和/或，第一通信节点标识和各通信节点标识对应的去激活信息以及去激活的频域索引(如BWP索引)。各第一通信节点监听到GC-PDCCH并解码成功后，可以根据指令，激活、去激活对应的频域(如BWP)，以及该频域上的configured grant或者SPS。
需要说明的是，上述由多个第一通信节点监听的公共PDCCH，可以由配置的计划-无线网络临时标识(Configured Scheduling-Radio Network Tempory Identity，CS-RNTI)，系统信息RNTI(System Information RNTI，SI-RNTI)，寻呼RNTI(Paging RNTI，P-RNTI)，中断RNTI(Interruption RNTI，INT-RNTI)，插槽格式指示RNTI(Slot Format Indication RNTI，SFI-RNTI)，发射功率控制-上行物理共享信道-RNTI(Transmit Power Control-Physical Uplink Shared Channel-RNTI，TPC-PUSCH-RNTI)，TPC-物理上行链路控制信道-RNTI(TPC-Physical Uplink Control Channel-RNTI，TPC-PUCCH-RNTI)，或者TPC-探测参考符号-RNTI(TPC-Sounding Reference Symbols-RNTI，TPC-SRS-RNTI)，其它RNTI加扰或者新的RNTI(例如NR-U-RNTI等)加扰。
进一步地，在本实施例步骤S701中，多个第一通信节点需要在第一条件下监听第二通信节点发送的信令。该第一条件可以包括以下任意一项：第一通信节点上传输第一业务，或者，第一通信节点在第一频谱上传输数据，或者，第一通信节点接收第二通信节点发送的指示消息，所述指示消息用于指示第一通信节点监听第二通信节点发送的信令。
例如，第一业务可以为时延要求高的业务，比如URLLC。当第一通信节点上传输这类时延要求高的业务时，第一通信节点可以认为上述公共PDCCH具有指示激活和/或去激活指定频域资源的功能，进而监听公共PDCCH。
第一频谱可以为非授权频谱等特点频谱，当第一通信节点在这类特点频谱上传输数据时，第一通信节点确认上述公共PDCCH具有指示激活和/或去激活指定频域资源的功能，进而监听公共PDCCH。
或者，第二通信节点通过系统信息或者RRC消息指示第一通信节点上述公共PDCCH具有指示激活和/或去激活指定频域资源的功能时，第一通信节点确认上述公共PDCCH具有上述功能，并进行监听。例如，系统信息或者RRC消息(如RRC重配消息)中携带一个信元，该信元指示某个公共PDCCH使能激活或去激活预配置的功能。
图9为本申请实施例提供的一种资源确定方法的流程图，如图9所示，该方法包括：
S901、第一通信节点获取第二通信节点配置的指示信息。
在本申请实施例中，第一通信节点可以为至少两个(或多个)通信节点，该第一通信节点可以为终端，第二通信节点可以为基站，即第一通信节点与第二通信节点是两种不同类型的通信节点。
示例性地，本实施例中的指示信息包括：竞争优先级，或者，是否降低竞争级别，或者，是否延迟竞争，或者，是否取消发送或者静默，或者，是否产生随机数。
S902、第一通信节点根据指示信息竞争预配置资源。
本步骤中的预配置资源可以为第二通信节点为多个第一通信节点配置的频域资源。例如，多个第一通信节点的预配置资源可以在相同的频域和相同的时刻，即在某个频域，可能会有多个第一通信节点的资源。如图10所示，第一通信节点1和第一通信节点2在时刻n都重叠在子带2。
在多个第一通信节点共享相同的频域资源的情况下，多个第一通信节点可以根据获取到的指示信息竞争预配置资源。
示例性地，假设步骤S902中的指示信息为竞争优先级，那么多个第一通信节点可以根据该竞争优先级竞争信道。例如，当两个第一通信节点的预配置产 生冲突时，第二通信节点可以为每个第一通信节点预配置一个竞争优先级，比如，若其中一个第一通信节点有时延要求高、可靠性高的业务(如URLLC)，则第二通信节点可以给该第一通信节点配置竞争高优先级；若其中一个第一通信节点没有时延要求高、可靠性高的业务，则第二通信节点给该第一通信节点配置竞争低优先级。
对于配置了低竞争优先级的第一通信节点，在竞争信道时将延迟竞争，延迟时间可以是随即产生，也可以由第二通信节点指定；或者，在竞争信道时限制竞争的时间，即低竞争优先级的第一通信节点只能在一定的竞争时间内竞争信道，如果没有成功就放弃竞争，竞争的时间可以由第二通信节点指定。第二通信节点配置或者指示竞争优先级的方法可以为RRC信令，DCI指示或者MAC CE，例如，RRC消息(如RRC重配消息)中携带一个信元，该信元指示某个预配置的竞争优先级为高优先级或者低优先级；或者MAC CE或者DCI指示携带一个比特，该比特指示某个预配置的竞争优先级，比如1为低优先级，0为高优先级。
若指示信息为是否降低竞争级别，则多个第一通信节点可以通过是否降低竞争级别的方式竞争信道。例如，第一通信节点可以采用竞争级别更低或者竞争时间更长的竞争机制。示例性地，该竞争机制可以为CAT2 25us，CAT2 16us，CAT4，CAT1，按照竞争时长从长到短的排序结果为CAT4>CAT 2 25us>CAT 2 16us>CAT1。假设第二通信节点以RRC信令，DCI指示或者MAC CE的方式配置指示信息，例如，RRC消息(如RRC重配消息)中携带一个信元，该信元使能某个预配置降低竞争级别，采用竞争时长更长的竞争机制；或者，MAC CE或DCI指示携带一个比特，该比特指示某个预配置降低竞争级别，1是降低竞争级别，采用竞争时长更长的竞争机制。第一通信节点接收到指示信息后，可以对某个预配置资源降低竞争级别，采用竞争时长更长的竞争机制获取信道接入权。
下面以具体示例对上述过程做进一步地详细描述，假设第一通信节点1和 第二通信节点2都可以采用CAT2 25us的竞争机制竞争信道。但第一通信节点1上具有时延要求高、可靠性高的业务(如URLLC)，第一通信节点上2没有时延要求高、可靠性高的业务，则第一通信节点1使用CAT2 25us的竞争机制，第一通信节点2使用比CAT2 25us更长竞争时长的竞争机制，例如CAT4。
若指示信息为是否延迟竞争，则多个第一通信节点可以通过是否延迟竞争的方式竞争信道。例如，当两个第一通信节点的预配置降低竞争级别冲突时，第二通信节点可以以指示信息的方式指示其中一个第一通信节点延迟竞争，指示方式可以是RRC消息配置或者DCI指示或MAC CE。例如，RRC消息(如RRC重配消息)中携带一个信元，该信元使能某个预配置进行延迟竞争，MAC CE或者DCI指示携带一个比特，该比特指示某个预配置是否延迟竞争，1表示需要延迟竞争。进一步地，该指示信息中可以携带延迟竞争的信息，例如，延迟时间。第一通信节点获取到指示信息后，根据指示信息延迟一定时间再竞争信道。该延迟时间可以是随即产生，也可以由第二通信节点指定。
示例性地，假设第一通信节点2上没有时延要求高、可靠性高的业务(如URLLC)，第一通信节点2获取到第二通信节点通过指示信息指示的延迟竞争，那么第一通信节点2在时刻n后延长一段时间后再竞争，或者在原本需要竞争的时刻再延长一段时间后再竞争，其中，延长一段时间基于延迟时间确定。
若指示信息为是否取消发送或者静默，则多个第一通信节点可以通过该指示信息竞争信道。例如，当多个第一通信节点的预配置冲突时，第二通信节点可以以指示信息的方式指示其中某个第一通信节点在某个频域或者时刻取消发送或者静默，指示方式可以是RRC消息配置或者DCI指示或MAC CE。进一步地，指示信息中可以携带取消发送信息的起始时刻，取消发送的时长(如，时隙，子帧，符号)。示例性地，RRC消息(如RRC重配消息)中携带一个信元，该信元使能某个预配置上的数据取消发送或者静默，或者，也可以携带取消发送的时间；MAC CE或者DCI指示携带一个比特，该比特指示某个预配置上的数据是否取消发送或者静默，1表示取消发送或者静默，进一步地，也可以携带 取消发送的起始时刻，取消发送的时长。第一通信节点获取到指示信息后，根据指示可以立刻执行取消发送，或者在一定时间后取消某个时刻(由取消发送的起始时刻决定)的发送，或者在一定时间后取消一段时间(由取消发送的起始时刻和取消发送的时长决定)的发送。
而且，该方法同样适用于通过一条信息或者指令(如RRC信令，DCI指示或者MAC CE)，通知多个用户的竞争优先级。例如，通过一个公共的PDCCH(GC-PDCCH)指示多个用户的预配置的取消发送或者静默，公共的PDCCH可以携带configured grant index，以及对应的是否采用取消发送或者静默。
若指示信息为是否产生随机数，则多个第一通信节点可以根据随机数竞争信道。例如，在第一通信节点在某个时刻某个频域上有预配置资源，且指示信息指示第一通信节点可以产生随机数的情况下，第一通信节点通过产生随机的大小决定是否竞争该预配置资源所在的信道。例如，假设第一通信节点产生0、1的随机数，当随机数为1时，表示竞争该预配置资源所在的信道，否则不竞争。该指示信息的指示方式可以是RRC信令，DCI指示或MAC CE。例如，RRC消息(如RRC重配消息)中携带一个信元，该信元使能某个预配置上的第一通信节点是否采用随机数决定是否竞争，进一步地，在采用随机数决定是否竞争的情况下，也可以携带随机数大小；MAC CE或者DCI指示携带一个比特，该比特指示某个预配置上的第一通信节点是否采用随机数决定是否竞争，比如，1为采用随机数决定是否竞争，进一步地，在采用随机数决定是否竞争的情况下，也可以携带几个比特以指示随机数的大小。
需要说明的是，上述指示信息可以通过一条信息或者指令(如RRC信令，DCI指示或者MAC CE)，通知多个第一通信节点。例如，通过一个公共PDCCH(GC-PDCCH)指示多个第一通信节点的预配置的竞争优先级，公共的PDCCH可以携带configured grant index，以及对应的竞争优先级，或者，是否降低竞争级别，或者，是否延迟竞争，或者，是否取消发送或者静默。
这样，在提高资源利用率，又避免了第一通信节点之间的竞争的情况，可 以有效保证第一通信节点上的业务的时延要求。
图11为本申请实施例提供的一种资源确定方法的流程图，如图11所示，该方法包括：
S1101、第二通信节点配置多个预配置资源。
本步骤中的预配置资源可以为第二通信节点为第一通信节点配置的时频域资源，例如，第二通信节点可以为第一通信节点配置多个配置授权configured grant，半持续性调度(Semi-Persistent Scheduling，SPS)。其中，第二通信节点与第一通信节点为两种不同类型的通信节点。例如，第一通信节点为终端，第二通信节点为基站。
S1102、第二通信节点配置配置信息。
上述第二通信节点配置的配置信息可以包括初传配置信息和/或重传配置信息，该配置信息用于指示第一通信节点根据配置信息在第二通信节点配置的多个预配置资源中选择目标资源。
S1103、第二通信节点将配置信息发送至第一通信节点。
示例性地，第二通信节点可以通过RRC消息，MAC CE或者DCI向第一通信节点发送配置信息。
其中，配置的初传配置信息包括以下任意一项：指示是否使能第一通信节点选择目标资源；或者，使能第一通信节点选择目标资源，并选择干扰最小的频域资源；或者，基于竞争机制选择目标资源；或者，指示第一通信节点根据参数信息选择目标资源，其中，参数信息包括第一通信节点标识、小区标识、随机数、频带信息中的任意一种。
例如，第二通信节点在RRC消息(如RRC重配消息)中携带一个信元，该信元指示是否使能第一通信节点选择资源的功能；或者MAC CE或者DCI指示携带一个比特，该信元指示是否使能第一通信节点选择资源的功能，比如，1为使能，0为不使能。
配置的重传配置信息包括以下任意一项：使能第一通信节点选择目标资源， 并基于重传数据包TBS选择干扰最小目标资源；或者，根据定时器和重传数据包TBS选择用于重传的目标资源；或者，根据预配置资源属性选择用于重传的目标资源，其中，第二通信节点为不同的预配置资源属性为抢占优先级或是否允许占用。
在一种示例中，第二通信节点可以给预配置资源配置上述定时器的时长。
在一种示例中，第二通信节点可以通过RRC信令或者DCI为每个预配置资源配置一个信元，该信元可以有几个比特，比特值标识抢占优先级的高低，例如，11表示抢占优先级3，10表示抢占优先级为2等，其中，抢占优先级高的预配置资源上传输的数据包传输失败时，可以占用抢占优先级相等或者预配置资源优先级低的资源进行重传。或者，第二通信节点通过RRC信令或者DCI为每个预配置资源配置一个信元，该信元可以有1个比特，例如，1表示允许被占用，0可以表示不允许被占用。如果某预配置资源被配置为不允许占用，则该预配置资源不能被用来重传在其他预配置资源上未传输成功的数据包。如果某个预配置资源被配置为允许占用，则该预配置资源可以用来传输在其他预配置资源上未传输成功的数据包。
图12为本申请实施例提供的一种资源确定方法的流程图，如图12所示，该方法包括：
S1201、第二通信节点配置多个预配置资源。
示例性地，第二通信节点配置多个预配置资源时，可以将多个第一通信节点配置在相同的频域，以及相同或不同的时域上。
S1202、第二通信节点发送信令至第一通信节点。
上述信令用于指示配置在预配置资源上的第一通信节点去激活指定资源，和/或，激活指定资源。
示例性地，上述信令可以为公共PDCCH，该公共PDCCH携带激活的配置信息，和/或，去激活的配置信息；
或者，公共PDCCH携带第一通信节点标识、激活的配置信息和/或去激活 的配置信息。
在一种示例中，第二通信节点还可以通过系统信息或者RRC消息指示第一通信节点监听上述公共PDCCH。例如，在系统信息或者RRC消息(如RRC重配消息)中携带一个信元，该信元可以指示某个公共PDCCH具有指示激活和/或去激活指定频域资源的功能。
图13为本申请实施例提供的一种资源确定方法的流程图，如图13所示，该方法包括：
S1301、第二通信节点配置多个预配置资源。
在本实施例中，第二通信节点配置多个预配置资源时，可以将一些第一通信节点配置在相同的频域和相同的时刻。其中，第一通信节点与第二通信节点是不同类型的节点。例如，第一通信节点为终端，第二通信节点为基站。
S1302、第二通信节点配置指示信息。
本步骤中的指示信息用于指示第一通信节点根据指示信息在第二通信节点配置的多个预配置资源中竞争频域资源。
S1303、第二通信节点将指示信息发送至第一通信节点。
示例性地，本实施例中的第一通信节点可以为多个第一通信节点，即第二通信节点可以通过一条信息或者指令(如RRC信令，DCI指示或者MAC CE)，将指示信息发送至多个第一通信节点。例如，通过一个公共PDCCH(GC-PDCCH)指示多个第一通信节点的预配置的指示信息，公共PDCCH可以携带configured grant index。
可选地，指示信息可以包括：竞争优先级，或者，是否降低竞争级别，或者，是否延迟竞争，或者，是否取消发送或者静默，或者，是否产生随机数。
第二通信节点将指示信息发送至第一通信节点，这样多个第一通信节点可以根据指示信息在多个预配置资源中竞争频域资源，从而避免多个第一通信节点在预配置的资源上出现资源冲突的问题。
图14为本申请实施例提供的一种资源确定方法的流程图，如图14所示， 该方法包括：
S1401、第二通信节点对资源进行划分。
在本申请实施例中，第二通信节点可以按照时域，和/或，频域的方式对资源进行划分。例如，将频带划分为多个部分，或者，按照时分的方式，将一定时间内的时刻划分为多个部分，或者，针对一定时间内时刻列表，对每个时刻内的带宽进行划分，或者，对带宽进行划分并指示带宽部分的时间，对每个带宽部分进行对应的时间划分。
S1402、第二通信节点通过接口消息将资源指示和对应的等级发送至相邻节点。
第二通信节点按照相应的划分方式对资源划分后，通过接口消息，例如，第二通信节点与相邻节点之间的Xn，X2接口，将划分后的资源指示和划分后每部分资源对应的等级发送至相邻节点，该过程如图15所示。该相邻节点为与第二通信节点同类型的节点。例如，假设相邻节点与第二通信节点均为基站。
可选地，第二通信节点也可以以系统信息或RRC消息的方式，将资源指示和对应的等级通知或配置至第一通信节点，第一通信节点可以是与第二通信节点不同类型的节点，例如，终端。
这样，通过接口消息与相邻节点交互频带划分信息，可以使相邻节点根据接收到的资源指示和对应的等级规避干扰大或者竞争激烈的频带，从而减少节点之间的资源竞争。
在本申请实施中，划分后的资源指示对应的等级可以包括竞争类型、竞争优先级、业务信息、资源类型、规避类型、预留资源。
示例性地，假设第二通信节点具有M Hz带宽，第二通信节点将其划分为N个部分。当等级对应竞争优先级时，该等级可以表示划分后N部分资源的优先级，比如，高、中、低，或者，高、低。如果某部分的资源为高竞争优先级，表示该部分资源可以承载竞争优先级高或时延要求高(如URLLC)的业务数据；如果某部分的资源为中竞争优先级，表示该部分可以承载竞争优先级较高或时 延要求较高的业务数据；如果某部分的资源为低竞争优先级，表示该部分可以承载竞争优先级低或时延要求低的业务数据。
当等级对应竞争类型时，例如，信道接入优先级(Channel Access Priority Classes，CAPC)＝1，CAPC＝2，CAPC＝3，CAPC＝4，表示划分后N个部分可以承载对应竞争类型的业务数据。
当等级对应业务信息时，例如，假设为承载时延要求不同的两种等级的业务。若等级为时延要求高的业务，则表示该部分资源可以承载时延要求高(如URLLC)的业务数据；若等级为时延要求低的业务，则表示该部分资源可以承载时延要求低的业务数据。
当等级对应资源类型时，该等级可以表示划分后N部分资源的资源类型，例如，高、中、低，或者，高、低。如果等级为高资源类型，表示该部分资源可以承载优先级高，业务时延要求高，竞争时延敏感，或干扰敏感的业务数据；如果等级为中资源类型，表示该部分资源可以承载优先级中等，业务时延要求中等，竞争时延较敏感，或干扰较敏感的业务数据；如果等级为低资源类型，表示该部分资源可以承载优先级低，业务时延要求低，竞争时延不敏感，或干扰不敏感的业务数据。
当等级对应规避类型或预留资源时，等级可以表示划分后N部分资源的每个部分是否为规避或预留资源，例如，是或否。如果是规避或预留资源，表示该部分资源可以承载优先级高，业务时延要求高，竞争时延敏感，或干扰敏感的业务数据；否则，则不可以承载优先级高，业务时延要求高，竞争时延敏感，或干扰敏感的业务数据。
这样，第二通信节点在发送数据时，可以根据数据的优先级、LBT的类型或服务质量(Quality of Service，Qos)参数等，将数据发送到不同部分的资源上。
在一种示例中，步骤S1402中第二通信节点划分后的资源指示可以包括以下内容：
第一种、资源指示包括每部分资源的起始位置、带宽和/终止位置，以及每部分资源对应的等级。
每部分带宽可以以X Hz带宽为粒度表示，而且，每部分可以是不连续的频带，也可以是连续的频带。例如，第二通信节点具有100Hz带宽，第二通信节点将带宽划分为3个部分，该3个部分分别对应a、b、c三个等级。其中，a可以对应用于最高优先级或时延要求最高或CAPC＝1的业务以及信令的传输，b可以对应用于较高优先级或时延要求较高或CAPC＝2，3的业务传输，c可以对应用于最低优先级或时延要求最低或CAPC＝4的业务传输。
假设以20MHz为粒度进行划分，那么部分1可以为起始位置为0，带宽为20MHz，终止位置为19MHz，对应等级a的频域资源，用于最高优先级或时延要求最高或CAPC＝1的业务以及信令的传输；部分2可以为起始位置为20MHz，带宽为40MHz，终止位置为59MHz，对应等级b的频域资源，可用于较高优先级或时延要求较高或CAPC＝2，3的业务传输；部分3可以为起始位置为60MHz，带宽为40MHz，终止位置为99MHz，对应等级c的频域资源，可用于最低优先级或时延要求最低或CAPC＝4的业务传输。
或者，以100RB为粒度进行划分，划分后的部分1可以为起始位置为0，带宽为100RB，终止位置为99RB，对应等级a的频域资源；部分2可以为起始位置为100RB，带宽为200RB，终止位置为299RB，对应等级b的频域资源；部分3可以为起始位置为300RB，带宽为200RB，终止位置为499RB，对应等级c的频域资源。
下面以具体示例对上述划分过程做进一步详细描述，假设第二通信节点具有100MHz带宽，将其划分为2个部分，分别对应1、0两个不同的等级，1可以对应用于最高优先级或时延要求最高或CAPC＝1的业务以及信令的传输，0可以对应用于低优先级或时延要求低或除CAPC＝1以外的业务的传输。假设以20MHz为粒度进行划分，那么划分后的部分1可以为起始位置为0，带宽为20MHz，终止位置为19MHz，起始位置为80MHz，带宽为20MHz，终止位置 为99MHz，对应等级1的频域资源；部分2可以为起始位置为20MHz，带宽为60MHz，终止位置为79MHz，对应等级0的频域资源。或者，以100RB为粒度进行划分，则划分后的部分1可以为起始位置为0，带宽为100RB(子载波间隔(Subcarrier Spacing，SCS)为15KHz)，终止位置为99RB，起始位置为300RB，带宽为100RB(SCS为15KHz)，终止位置499RB，对应等级1的频域资源；部分2可以为起始位置为100RB，带宽为300RB，终止位置为299RB，对应等级0的频域资源。
第二种、资源指示用字符串表示，字符串中的每个字符对应一个资源部分的等级。
字符串中的每个字符表示一个等级，并对应X MHz的带宽。例如，假设第二通信节点具有100MHz带宽，将其划分为3个部分，该3个部分分别对应a、b、c三个等级，a可以对应用于最高优先级或时延要求最高或CAPC＝1的业务以及信令的传输，b可以对应用于较高优先级或时延要求较高或CAPC＝2，3的业务传输，c可以对应用于最低优先级或时延要求最低或CAPC＝4的业务传输。
假设以20MHz为粒度进行资源划分，划分后的字符串为abbca，划分后的资源0～19MHz，80～99MHz对应等级a，20～59MHz对应等级b，60～79MHz对应等级c。相应地，也可以100RB为粒度对上述资源进行划分。
或者，第二通信节点可以100MHz将带宽划分为2个部分，2个部分分别对应1、0两个等级，1可以对应用于最高优先级或时延要求最高或CAPC＝1的业务以及信令的传输，0可以对应用于低优先级或时延要求低或除CAPC＝1以外的业务的传输。假设以20MHz为粒度进行资源划分，划分后的比特串为10001，划分后的资源0～19MHz，80～99MHz对应等级1，20～79MHz对应等级0。同样地，也可以100RB为粒度对上述资源进行划分。
需要说明的是，上述划分过程中所涉及的等级个数、划分粒度等可以配置，也可以通过接口消息进行指示。
第三种、资源指示为第一时间内，每个时刻部分的资源以及对应的等级。 其中，该第一时间可以为一定时间，即第二通信节点将一定时间内的时刻划分为N个部分，每部分对应一种等级。
示例性地，上述将一定时间内的时刻划分为N个部分，每部分可以包括每个时刻部分的起始时间，持续时间，终止位置，或者周期，以及每个部分对应的等级，每部分可以以多个子帧、时隙、ms、符号为粒度进行互粉，而且每个部分可以是不连续的时间，也可以是连续的时间。上述一定时间可以为固定的时长，也可以为配置的时长，并按照一定时间周期性在时间上出现。
下面以举例示例对上述的划分方式做进一步的详细描述，假设第二通信节点将10ms的时间划分为3个部分，该3个部分分别对应a、b、c三个等级，其中，a可以对应用于最高优先级或时延要求最高或CAPC＝1的业务以及信令的传输，b可以对应用于较高优先级或时延要求较高或CAPC＝2，3的业务传输，c可以对应可用于最低优先级或时延要求最低或CAPC＝4的业务传输。假设以2ms为粒度进行划分，那么划分后的时刻部分1可以为起始时刻为0，持续时间为2ms，周期为4ms，对应等级为a的资源，例如，时刻为0～1ms、4～5ms、8～9ms；时刻部分2可以为起始时刻为2，持续时间为2ms，周期为10ms，对应等级b的资源，例如时刻为2～3ms；部分3可以为起始时刻为6，持续时间为2ms，周期为10ms，对应等级c的资源，例如时刻为6～7ms。
或者，第二通信节点将上述10ms时间划分为2个部分，每部分分别对应1、0两个等级，其中，1可以对应用于最高优先级或时延要求最高或CAPC＝1的业务以及信令的传输，0可以对应用于低优先级或时延要求低或除CAPC＝1以外的业务的传输。假设以2ms为粒度进行划分，则划分后的时刻部分1可以为起始时刻为0，持续时间为2ms，周期为4ms，对应等级1的资源，例如，时刻为0～1ms、4～5ms、8～9ms；时刻部分2可以为起始时刻为2，持续时间为2ms，周期为4ms，对应等级0的资源，例如时刻为2～3ms，6～7ms。
或者，将一定时间内的时刻划分为N个部分后，可以用字符串表示划分指示，每个字符表示一个等级，并对应一定的持续时间。例如，假设第二通信节 点将10ms时间划分为多个部分，每个部分分别对应a、b、c三个等级中的一个，其中，a可对应用于最高优先级或时延要求最高或CAPC＝1的业务以及信令的传输，b可对应用于较高优先级或时延要求较高或CAPC＝2，3的业务传输，c可对应用于最低优先级或时延要求最低或CAPC＝4的业务传输。每个部分持续2ms。假设字符串为abacc，可以表示0～1ms、4～5ms对应等级a，2～3ms对应等级b，6～9ms对应等级c。
或者，第二通信节点将10ms时间划分为2个部分，分别对应1、0两个等级，其中，1可对应用于最高优先级或时延要求最高或CAPC＝1的业务以及信令的传输，0可对应用于低优先级或时延要求低或除CAPC＝1以外的业务的传输。每个部分持续2ms。假设字符串为10100，可以表示0～1ms、4～5ms对应等级1，2～3ms，6～9ms对应等级0。
需要说明的是，上述一定时间可以周期性出现，例如，一定时间为10ms，那么每个10ms内都会按照时刻划分信息周期性出现，并通过接口消息进行指示。另外，上述等级个数、粒度等可以配置，也可通过接口消息进行指示。
第四种、资源指示为对第一时间内每个时刻的带宽进行划分，换分后的每部分包括资源的起始位置、带宽、终止位置、以及每部分资源对应的等级。
在一定时间内，每个时刻内带宽划分可以不同。第二通信节点可以指示一个一定时间内的时刻列表，并对每个时刻内的带宽再进行划分，划分后的资源对应相应的等级。每个时刻内的带宽划分方法可以采用上述第一种或第二种方式。例如，假设一定时间为10ms，第二通信节点以2ms为粒度进行划分，那么需要一个大小为5的列表，并对列表中的每一项再进行带宽划分。
第五种、资源指示为对每部分频带资源对应的时间进行划分，划分后的每部分包括起始时间、持续时间、终止时间或周期，以及每部分资源对应的等级。
第二通信节点将带宽划分成多个部分，并对每个带宽部分对应的时间进行划分，划分后的每部分资源对应相应的等级。其中，对每个带宽部分对应的时间进行划分可以采用上述第三种划分方式。例如，划分后的部分1可以为起始 位置为0，带宽为20MHz，终止位置为19MHz，对应等级a的资源，并在10ms内占用0～1ms、4～5ms、8～9ms。
图16为本申请实施例提供的一种资源确定方法的流程图，如图16所示，该方法包括：
S1601、节点通过接口消息接收第二通信节点发送的资源指示和对应的等级。
本步骤中的节点为与第二通信节点相同类型的节点。例如，节点与第二通信节点均为基站。节点接收的资源指示和对应的等级为第二通信节点按照频域和/或时域的方式对资源进行划分后的指示和等级。
S1602、节点根据资源指示和对应的等级对自身的资源进行划分。
示例性地，假设第二通信节点按照频域的方式对资源进行划分，那么节点接收到的资源指示和对应的等级即为频域划分后的资源指示和对应等级，这样节点可以根据收到的第二通信节点发送的资源指示，划分自己的频带，以将避免最高优先级或时延要求最高业务调度到与第二通信节点相同的频带上。例如，对于第二通信节点高优先级的资源部分，节点可以不在相应的频带位置调度时延要求较高的业务。对于第二通信节点低优先级的资源部分，节点可以在相应的频带位置调度时延要求较高的业务。举例，对于第二通信节点的最高优先级的频带或者对应等级最高的频带(例如，对应等级a)，则节点可以规划为低优先级或者对应低等级的频带。对于第二通信节点最低优先级的频带或者对应等级最低的频带(例如，对应等级c)，则节点可以规划为最高优先级或者对应最高等级的频带的部分。
这样，通过对资源划分指示以及对应等级的交互，节点与第二通信节点可以规避干扰大或竞争激烈的频带，从而减少节点之间的相互竞争。
可选地，如图17所示，节点在接收到第二通信节点发送的资源指示和对应等级的信息后，可以回复响应消息，并将自己的资源划分信息反馈给第二通信节点，实现两个节点之间的协商。或者，节点也可以不反馈信息。
示例性地，节点接收到的资源指示可以包括每部分资源的起始位置、带宽、 终止位置，以及每部分资源对应的等级；
或者，资源指示用字符串表示，字符串中的每个字符对应一个资源部分的等级；
或者，资源指示为第一时间内，每个时刻部分的资源以及对应的等级。
资源指示对应的等级可以包括竞争类型、竞争优先级、业务信息、资源类型、规避类型、预留资源。
