技术领域
本申请属于通信技术领域，具体涉及一种资源指示方法、终端及网络侧设备。
背景技术
长期演进(Long Term Evolution，LTE)系统长从第12个发布版本开始支持旁链路(Sidelink，或译为副链路，侧链路，边链路等)传输，即终端(User Equipment，UE)之间直接在物理层上进行数据传输。LTE Sidelink是基于广播进行通讯的，虽然可用于支持车联网(vehicle to everything，V2X)的基本安全类通信，但不适用于其他更高级的V2X业务。5G NR(New Radio，新无线/新空口)系统将支持更加先进的Sidelink传输设计，例如，单播，多播或组播等，从而可以支持更全面的业务类型。
在未来通信系统中，Sidelink的非授权频段(unlicensed band)可以作为授权频段(licensed band)的补充帮助运营商对服务进行扩容。然而，在非授权频段，需要满足OCB(OccupiedChannel Bandwidth，非授权频段针对发送信号的占用带宽)要求，即每次传输需要占满LBT(Listen before Talk，先听后说)带宽的80％。但是，目前在非授权频段上仍然缺乏有效的资源指示方式。

下面结合附图，通过一些实施例及其应用场景对本申请实施例提供的资源指示进行详细地说明。
第一方面，参见图2所示，为本申请实施例所提供的一种资源指示方法的实施流程图，该方法可以包括以下步骤：
步骤201、第一终端根据子信道和/或资源组的编号规则发送旁链路控制信息，其中，所述子信道和/或资源组的编号规则包括子信道和交错资源之间的映射规则，所述旁链路控制信息包括资源指示信息，所述资源指示信息用于指示所述第一终端占用和/或预留的资源。
在具体实现中，为了与NR部署保持一致并尽可能的最大化基于NR的非授权频段接入，非授权频段可以工作在5GHz，37GHz和60GHz频段。非授权频段的大带宽(80MHz或者100MHz)能够减小基站和UE的实施复杂度。由于非授权频段由多种无线接入技术(RAT，Radio Access Technology)共用，例如WiFi，雷达，长期演进-授权频谱辅助接入(long term evolution-licensed-assisted access，LTE-LAA)等等，因此在某些国家或者区域，非授权频段在使用时必须符合regulation(规则)以保证所有设备可以公平的使用非授频段的资源，例如LBT(listen before talk，先听后说)，MCOT(maximum channel occupancy time，最大信道占用时间)等规则。当传输节点需要发送信息时，需要先做LBT时，对周围的节点进行功率检测(energy detection，ED)，当检测到的功率低于一个门限时，认为信道为空(idle)，传输节点可以进行发送。反之，则认为信道为忙，传输节点不能进行发送。其中，传输节点可以是基站，UE，WiFi AP等等。传输节点开始传输后，占用的信道时间COT(Channel OccupancyTime，信道占用时间)不能超过MCOT。此外，根据OCB要求，在非授权频段上，传输节点在每次传输时要占用整个频带的至少70％(60GHz)或者80％(5GHz)的带宽。
在NRU中常用的LBT的类型(type)可以分为Type1，Type2A，Type2B和Type2C。Type1LBT是基于回退(back-off)的信道侦听机制，当传输节点侦听到信道为忙时，进行回退，继续做侦听，直到侦听到信道为空。Type2C是发送节点不做LBT，即no LBT 或者immediate transmission。Type2A和Type2B LBT是one-shot LBT，即节点在传输前做一次LBT，信道为空则进行传输，信道为忙则不传输。区别是Type2A在25us内做LBT，适用于在共享COT时，两个传输之间的gap(时间间隔)大于等于25us。而Type2B在16us内做LBT，适用于在共享COT时，两个传输之间的gap等于16us。此外，还有Type2LBT，适用于LAA/eLAA/FeLAA，当共享COT时，两个传输之间的gap大于等于25us，eNB和UE可以采用Type 2LBT。此外，在frequency range 2-2中，LBT的类型有Type1，Type2和Type3.Type1是基于回退的信道侦听机制，Type2是one-shot LBT，在8us内做5us的LBT，Type3是不做LBT。
目前在Sidelink中，第一终端只会在传输所在的资源上发送一个SCI(Sidelink Control information，旁链路控制信息)，且SCI承载的资源指示域会以subchannel(子信道)为单位指示此次传输的资源，其中，subchannel可以包括1个interlace或者多个interlace。但是，由于在非授权频段上传输时，PSSCH(Physical Sidelink Shared Channel，物理旁链路共享信道)等信道接入的单位是RB set，且需要满足OCB需求，因此引入interlace(交错资源)来满足非授权频段的规则。具体地，通过引入interlace，可以充分利用非授权频段，以及能满足OCB规定，资源分配时利用了interlace结构，一个interlace由均匀分布在系统带宽上的整数个资源块(RB，Resource Block)组成，资源指示时以interlace为基本单位，分配给每个终端的资源至少为一个interlace。在非授权频段上，终端需要先执行LBT，当LBT成功后才可以进行传输，LBT的单位是RB set(资源组)，具体地，1个LBT通常占20MHz的带宽，Sidelink整个非授权频段的载波带宽基于LBT被划分为多个RB set，举例来说，终端配置的BWP(Bandwidth Part，部分带宽)的带宽是40MHz、60MHz、80MHz等，如果BWP是40MHz，则可以有2个LBT(或者说是2个RB set)，如果BWP是60MHz，则可以有3个LBT(或者说是3个RB set)，如果BWP是80MHz，则可以有4个LBT(或者说是4个RB set)，其中，每个RB set由多个interlace组成。为了尽量保留Sidelink的已有框架，在非授权频段上进行资源选择，资源指示和资源排除，本申请实施例研究了subchannel和RB set的interlace之间的关系。
在本申请实施例中，subchannel和interlace的关系可以通过subchannel和/或RB set的编号规则实现，其中，subchannel和/或RB set的编号规则可以包括subchannel和interlace之间的映射规则。具体地，在第一终端与其他终端，例如第二终端进行通信时，第一终端以subchannel为单位指示需要占用或者预留的资源，然后根据subchannel和/或RB set的编号规则发SCI至第二终端，其中，SCI包括资源指示信息(FRIV，Frequency reservation indicator value)，资源指示信息用于指示第一终端占用和/或预留的资源，第二终端接收到资源指示信息后，就可以根据资源指示信息确认第一终端占用或者预留的资源。其中，第一终端占用的资源指的是发送SCI的slot(时隙)上用于传输第一对象的资源，还可以描述为用于传输或发送的资源。
具体地，资源指示信息用于指示第一终端在非授权频段的第一对象占用的资源，资 源可以包括频域资源和时域资源，其中，第一对象包括以下至少一项：
PSCCH(Physical Sidelink Control Channel，物理旁链路控制信道)；
PSSCH(Physical Sidelink Shared Channel，物理旁链路共享信道)；
PSFCH(Physical Sidelink Feedback Channel，物理旁链路反馈信道；
SSB(Synchronization Signal，同步广播块)等等。
由上述步骤201可知，在本申请实施例中，第一终端根据子信道和/或资源组的编号规则发送旁链路控制信息，其中，子信道和/或资源组的编号规则包括子信道和交错资源之间的映射规则，旁链路控制信息包括资源指示信息，资源指示信息用于指示第一终端占用和/或预留的资源。本申请实施例预先配置子信道和交错资源之间的映射规则，然后将子信道和交错资源之间的映射规则用于在非授权频段上资源指示，使得第一终端可以根据子信道和交错资源之间的映射规则来指示其占用或者预留的资源，可以满足非授权频段上OCB等规则，且可以不改变Sidelink的已有框架，保证了资源的利用率，以及在不同场景下保证了收发两端的通信，以及如何进行资源指示和资源分配的问题，可以适应未来潜在的多样化应用场景和各种需求。
在本实施例中，资源组可以是RB set,channel,PRB的集合等。
作为一个可选实施例，所述子信道和/或所述资源组的编号规则满足以下至少一项：
所述子信道包括1个交错资源；
或者，
所述子信道包括K个交错资源，所述资源组包括M个交错资源，所述K和所述M为整数，可选地，所述K是所述M的约数，或者，所述K不是所述M的约数。
在Sidelink的非授权频段(SLU)中，subchannel的大小可以被固定为1个interlace，也可能是可配置，例如配置为subchannel等于K个interlace，此时subchannel的大小就随着K的配置值而变化，使得配置更加灵活。
具体地，当subchannel由K个interlace组成时，且此时RB set包括M个interlace，可选地，此时K可以是M的约数(或者说M是K的倍数)，或者，K可以不是M的约数。
作为一个可选实施例，当所述K不是所述M的约数，对所述M和所述K进行取模运算得到的余数为m时，所述m为整数，其中，所述子信道和/或所述资源组的编号规则满足以下至少一项：
所述资源组中的子信道从第m+1个交错资源开始编号；
所述资源组中的子信道从第1个交错资源开始编号。
当配置的K不是M的约数时，假设对M和K进行取模运算得到的余数为m，即mod(M,K)＝m，则此时subchannel和/或RB set的编号规则满足以下至少一项：
A-1项：起始subchannel从第m+1个interlace开始编号；
A-2项：起始subchannel从第1个interlace开始编号；
此外，对于多余的m个interlace可以进行如下处理：
A-3项：多余的m个interlace不被用于传输；
A-4项：多余的m个interlace组成一个subchannel；
A-5项：多余的m个interlace都被配置为guard band(保护频段)；
A-6项：多余的m个interlace被配置在guard band的相邻频域。
其中，非授权频段包括对应的第二对象，第二对象可以包括以下至少一项：载波；部分带宽(bandwidth part，BWP)；资源池(resource pool)；虚拟资源池；虚拟部分带宽；可指示资源范围。
在本申请实施例中，当subchannel等于K个interlace时，而此时RB set或第二对象是由M个interlace组成时，可能会出现K无法被M整除的情况，在这种情况下，需要定义剩余的interlace如何处理。例如，此时起始subchannel可以是从interlace 0(第1个interlace)开始编号，即将频域位置最高的m个interlace空出来，则这些interlace不会被用于传输和/或接收。同时，此时起始subchannel可以是从interlace m(第m+1个interlace)开始编号，还可能是位置最低的m个interlace空出来。又或者，将这些interlace配置为guard band，或配置在guard band的频域相邻位置，起到更好的隔离带宽的作用。除此之外，额外的m个interlace还可以被编为一个特殊的subchannel，如此终端仍然可以使用这些interlace进行传输。
作为一个可选实施例，所述子信道和/或所述资源组的编号规则包括以下至少一项：
B-1项：在第二对象上，所述子信道的子信道索引从0开始，按频域由低到高或由高到低的顺序增加；
B-2项：在第二对象上，所述子信道的子信道索引从第一起始序号开始，按频域由低到高或由高到低的顺序增加；其中，第一起始序号由网络侧设备配置或预配置，或终端确定；例如，终端会根据指示给自己的第一起始序号，在资源池内对subchannel进行编号，此时资源池的起始subchannel不再是0，而是第一起始序号。
B-3项：在至少部分资源组上，所述子信道的子信道索引从0开始，按频域由低到高或由高到低的顺序增加；例如，每个资源组上的子信道的索引都从0开始，或者从第二个资源组从0开始。
B-4项：在至少部分资源组上，所述子信道的子信道索引从第一起始序号开始，按频域由低到高或由高到低的顺序增加；
B-5项：在至少部分资源组上，所述子信道的子信道索引从所述资源组上频域位置最低或最高的交错资源的索引开始，按频域由低到高或由高到低的顺序增加；
B-6项：在第二对象上，所述资源组的资源组索引从0开始，按频域由低到高或由高到低的顺序增加；
B-7项：在第二对象上，所述资源组的资源组索引从第二起始序号开始，按频域由低到高或由高到低的顺序增加；其中，第二起始序号由网络侧设备配置或预配置，或终端 确定。例如，终端会根据指示给自己的第二起始序号，确认资源池内的RB set的索引，以便于理解接收到的资源指示，或自己进行资源指示。
此时，子信道对应的interlace可能是与子信道索引相同的interlace，或者索引上加一个偏移值的interlace,或者是频域内顺序相同的interlace等，具体参照子信道与interlace之间的映射规则。
在本申请实施例中，在对subchannel和RB set编号时，subchannel的子信道索引(subchannel index)在第二对象的起点与interlace的交错资源索引(interlace index)的起点可以不同，或者subchannel index的起点与interlace的interlace index在第二对象的起点可以相同。
具体地，在对subchannel进行编号时，subchannel index在第二对象进行编号，也可以在部分资源组上进行编号，其中，subchannel index可以从第一起始序号开始，也可以从0开始，按频域由低到高或由高到低的顺序增加。对RB set进行编号时，interlace index在第二对象进行编号，其中，interlace index可以从第二起始序号开始，也可以从0开始，按频域由低到高或由高到低的顺序增加。
在本申请实施例中，当subchannel在RB set内编号，FRIV指示的P个资源位于同一个RB set内(此时，一个FRIV只可以预留当前RB set内的资源，以节省开销，且更符合subchannel独立编号的出发点)。当subchannel在RB set内编号，且PSSCH所在的每个RB set内都发送FRIV时，第一指示信息包括第一RB set指示，所述第一Rb set指示用于指示FRIV的后P-1个资源所在的RB set标识(index或相对当前RB set的位置/gap)。
具体地，当1subchannel＝1interlace,或者说interlace在一个RB set内的部分
1、subchannel index＝interlace index(此时subchannel在每个RB set里面独立编号)。
2、subchannel index＝RB set index*interlace number+interlace index(此时subchannel在resource pool里面编号,假设从0开始)。例如，参照图3，是本发明实施例提供的一种subchannel与interlace的关系的示意图之一，图中包括RB set 0和RB set 1两个RB set，其中，每个RB set分别包括10个interlace。在第一个RB set(RB set 0)时，subchannel index可以与RB set 0的interlace index相同，例如在图3中，subchannel index 0对应RB set 0中的interlace index 0，……subchannel index 9对应RB set 0中的interlace index 9，然后，subchannel index随着第二个RB set(即RB set 1)内的subchannel index会在interlace index的基础上加上RB set 0的interlace number(交错资源数目，此处为10个)，例如在图3中，subchannel index 10对应RB set 1中的interlace index 2，……subchannel index 19对应RB set 0中的interlace index 1。
当1subchannel＝K interlace时，或者说interlace在一个RB set内的部分。
1、subchannel index＝interlace(K*index+1)～interlace(K*(index+1))。
作为一个可选实施例，所述子信道和所述交错资源之间的映射规则包括以下至少一 项：
C-1项：所述子信道的子信道索引编号与对应的每个所述资源组中的所述交错资源的交错资源索引相同；即，子信道包括与所述子信道索引相同的交错资源，或资源组内与所述子信道索引相同的资源。例如，子信道0会映射到index为0的交错资源上，或者说index为0的interlace会映射到subchannel 0上。进一步的解释，当终端指示的资源为subchannel 0时，这个资源的实际物理资源位置是在interlace 0上。
C-2项：所述子信道的子信道索引编号随着对应的每个所述资源组的资源组标识和所述资源组的所述交错资源的交错资源索引的增加相应增加；例如，在RB set 0里面，子信道索引为1的资源会映射到interlace 1上，但是随着频域的增加，子信道的索引也会随之增加，此时，假设每个RB set里面包含5个subchannel，因此在RB set 1里面，此时interlace1的资源会映射到子信道5上面，或者说与子信道5对应。
C-3项：所述子信道包括资源组内与所述子信道索引顺序相同的交错资源；例如，资源组内第一个子信道的资源会映射到第一个interlace的资源上，因为此时资源组的起始interlace index可能与起始subchannel index不同。
C-4项：所述子信道包括资源组内与所述子信道索引相差N的交错资源，其中，N为比所述资源组频域更高或频域更低的资源组包括的总子信道数目；
C-5项：第一个所述资源组中，所述子信道的子信道索引与对应的第一个所述资源组的交错资源的交错资源索引相同；
C-6项：第一个所述资源组中，所述子信道的子信道索引从0开始，按顺序进行编号。所述顺序可以是频域顺序，例如频域从低到高的顺序，或者频域从高到低的顺序。
可选地，所述subchannel和/或所述RB set的编号可以由协议预定义或根据第二对象的配置和/或预配置确定，所述RB set的资源组标识可以通过协议预定义、网络侧设备预配置、配置和/或所述第一终端确定，本申请实施例均对此无需加以限制。
示例性地，参照图4，是本发明实施例提供的一种subchannel与interlace的关系的示意图，图中包括RB set 0和RB set 1两个RB set，其中，每个RB set分别包括10个interlace。
对于C-1项，参照图4，在RB set 0中，subchannel包括RB set 0内与子信道索引相同的交错资源，例如，subchannel index 0对应RB set 0中的interlace index 0，……subchannel index 9对应RB set 0中的interlace index 9。
对于C-2项：subchannel包括资源组内与subchannel index相差一个偏移值的interlace，其中，偏移值为整数，例如，偏移值可以2。
对于C-3项，参照图4，在RB set 1中，subchannel包括RB set 1内与subchannel index顺序相同的interlace，例如subchannel index 0对应RB set 1中的interlace index 2,……subchannel index 9对应RB set 1中的interlace index1。
对于C-4项，subchannel包括RB set内与subchannel index相同的interlace，例如，都包括index 0、index 1等等。
对于C-5项，第一个RB set中，subchannel的subchannel index与对应的第一个RB set的interlace的interlace index相同，例如，index都是1，都是2等等。
对于C-6项，第一个RB set中，subchannel的subchannel index从0开始，按顺序进行编号，例如，0，1，2……9。
作为一个可选实施例，第一资源组中子信道与交错资源的映射规则与最低或最高资源组中子信道与交错资源的映射规则相同，所述第一资源组为最低或最高资源组之外的其他资源组。
可以理解的是，所述子信道和所述交错资源之间的映射规则包括：
资源池或其他第二对象上的第一资源组中子信道和所述交错资源之间的映射规则相同，且都等于最低RB set子信道和所述交错资源之间的映射规则。此时第一资源组为第二对象上除最低RB set之外的所有RB set。例如，在一个资源池中，最低RB set上的sub-channel index是从0开始的，而此时RB set上的最低PRB属于interlace 0，则此RB set上属于interlace 0的PRB都属于或者说映射到sub-channel 0中，而属于interlace 1的PRB都属于或者说映射到sub-channel 1中，以此类推。则在频域位置更高的RB set 1等RB set上，属于interlace 0的PRB也都属于或者说映射到RB set 1中的sub-channel 0中，属于interlace 1的PRB都属于或者说映射到RB set 1中的sub-channel 1中，以此类推。又例如，在一个资源池中，最低RB set上的sub-channel index是从0开始的，且此RB set上属于interlace 2和interlace 3的PRB都属于或者说映射到sub-channel 0中，而属于interlace 4和interlace5的PRB都属于或者说映射到sub-channel 1中，，而由于资源池中只有10个interlace,则属于interlace 0和interlace 1的PRB都属于或者说映射到sub-channel 5中，以此类推，循环往复。则此时，在频域位置更高的RB set 1等RB set上，RB set 1中的属于interlace 2和interlace 3的PRB都属于或者说映射到RB set 1中的sub-channel 0中，而属于interlace 4和interlace5的PRB都属于或者说RB set 1中的映射到sub-channel 1中，属于interlace 0和interlace 1的PRB都属于或者说映射到sub-channel 5中，以此类推，循环往复。可以看到，这也可以描述为所有资源组中子信道与interlace的映射规则相同。例如，每个资源组中subchannel 0对应的都是此资源组中的interlace 0和interlace 1。
作为一个可选实施例，所述旁链路控制信息，包括以下至少一项：
D-1项：所述旁链路控制信息中的资源指示信息中的子信道的起始位置根据第二对象的配置和/或预配置确定；
D-2项：所述旁链路控制信息中的资源指示信息根据子信道的总个数确定，其中所述子信道的总个数根据第二对象的配置和/或预配置确定；
D-3项：所述旁链路控制信息中的资源指示信息根据资源组的起始位置确定，其中所述资源组的起始位置根据第二对象的配置和/或预配置确定；
D-4项：所述旁链路控制信息中的资源指示信息根据资源组的总个数确定，其中所述资源组的总个数由协议预定义，或第二对象配置、预配置。
其中，所述第二对象的配置和/或预配置可以包括第一起始序号，第二起始序号，所述子信道的起始位置、所述子信道的总个数、所述资源组的起始位置，所述资源组的总个数中的至少一项。
作为本申请的一个可选示例，第二对象预配置/配置包括以下内容的至少之一：
1)第一起始序号(例如可以是2等)，第二起始序号(例如可以是3等)；例如，资源池上的第一个subchannel的起始序号可以是第一起始序号。资源池上的第一个RB set的起始序号可以是第二起始序号。
2)频带的起始位置，例如某个物理PRB，start subchannel(子信道的起始位置)、start RB set(资源组的起始位置)和/或RB set index(资源组标识)和/或interlace index(交错资源索引)等，即终端被配置一个start subchannel，start subchannel是一个全局位置，终端在资源指示时可以基于start subchannel，便于其他终端理解；
2-1)例如，starting PRB表示资源池的起始位置(相对于BWP起始位置的相对位置)；
2-2)可选地，Subchannel start index是资源池内第一个subchannel的起始位置；
2-3)可选地，RB start index是该资源池内第一个RB set的起始位置；
2-4)可选地，RB set index+interlace index表示资源池的起始位置；
3)第一对象，即载波/BWP/资源池/可指示频域资源范围/虚拟资源池/虚拟BWP的大小，例如，subchannel number(子信道的总个数)，RB set number(子信道的总个数)等(便于终端根据此参数进行FRIV编码)；
3-1)第一对象，即载波/BWP/资源池/可指示频域资源范围/虚拟资源池/虚拟BWP指的是实际配置的大小，例如R16中RRC(Radio Resource Control，无线资源控制)参数指示的资源池的大小；
3-2)第一对象，即载波/BWP/资源池/可指示频域资源范围/虚拟资源池/虚拟BWP的大小指的是网络配置/预配置给终端的一个辅助参数，此参数表示终端在用SCI指示频域资源时，需要基于此参数指示的频域范围大小计算FRIV，而不是终端本身支持的频域范围。
在商业场景下，终端可能是一种能力受限终端。具体地，所述的能力受限终端指的是硬件或软件能力只支持特定带宽上限或存在解调能力上限等其他能力的终端。例如，终端可能只支持20MHz带宽的终端，此时，如果能力受限终端配置了较大带宽(例如80MHz)的频段或资源池上时，则终端只能对其中的20MHz进行检测、解调等，而对于80MHz中除这20MHz之外无法进行检测、调解等。在这种情况下，需要考虑的场景在较大带宽的频段或资源池内，如果要支持能力受限终端与其他终端通信，则在资源指示、资源预留等方面需要保证能力受限终端的理解与其他终端一致，否则会导致能力受限终端与其他终端出现通信相关问题。
参照图5，假设终端A是一个能力受限终端，当终端A指示它自己占用或者预留的资源时，如果subchannel的编号是按照终端A支持的带宽进行编号的，例如图5中的上 方的RB set,那么终端A预留的资源subchannel 0～subchannel 5，在终端A自己看来是图5中的RB set 1的资源块，可是对于其他终端来说，如果其他终端支持图5中全部的带宽，即支持RB set 0和RB set 1这两个RB set的带宽，那么其他终端在检测终端A的资源指示，预留的资源就会被理解为RB set 0的资源块，导致终端A与其他终端出现通信相关问题。
针对上述能力受限终端存在问题，在本申请实施例中，可以采用以下几种方法解决：
作为一个可选方式，编号时统一subchannel的起点和/或interlace的起点，则在所有配置在第二对象(例如载波/BWP/resource pool等)上的终端看来，subchannel和interlace有一个相同的起点。则此时，不管终端工作在哪个频点或能力是否受限，指示的subchannel和interlace都是唯一的，此时不会出现对资源位置的理解不同的问题，如图6所示，subchannel index和RB set都是基于Virtual resource pool(虚拟资源池)编号，其中，subchannel number(子信道编号)表示配置整个频域范围，Operation bandwidth(操作带宽)表示的是终端在整个频域范围内支持的带宽，其中，start subchannel index(起始子信道索引)为终端支持的带宽的第一个subchannel的子信道索引。对于能力受限终端，虽然它只支持较少的带宽，但是网络侧设备会给它指示一个start subchannel index和subchannel number，使得终端知道自己所在的第二对象在整个subchannel和interlace编号频域范围的位置，以及subchannel和interlace的个数，方便终端进行资源指示。例如，如图5所示，终端A会被配置/指示start subchannel是10，整个频域范围是20，则终端A在指示预留的RB set 1的资源块时，指示的subchannel会是subchannel 10～subchannel1 5，而不再是subchannel 0～subchannel 5。
作为另一个可选方式，每个subchannel和interlace都在RB set上独立编号，终端在指示资源时需要携带RB set标识，此时RB set的index(资源组标识)是唯一的，如此终端A和与其他终端就不会出现对资源位置理解不同的问题。
作为一个可选实施例，所述第一终端发送旁链路控制信息，包括以下至少一项：
E-1项：所述第一终端在资源组上发送旁链路控制信息，其中，所述旁链路控制信息包括资源指示信息和/或关联信息；
E-2项：所述第一终端在资源组集合上发送旁链路控制信息，其中，所述资源组集合为所述第一对象的所述资源组中的部分资源组，或指定资源组，或首要资源组；所述旁链路控制信息包括资源指示信息和/或关联信息；所述特定资源组和/或首要资源组由协议预定义，或网络预配置，或网络配置，或终端确定。
作为一个可选实施例，所述关联信息包括以下至少一项：
F-1项：所述第一终端占用的资源所在的资源组的资源组标识；
F-2项：所述第一终端占用的资源所在的部分资源组的资源组标识；
F-3项：所述第一终端占用的资源所在的资源组中与所述旁链路控制信息所在的资源组中的资源相对资源组的起始位置相同的资源组的资源组标识；
F-4项：所述第一终端占用的资源所在的资源组中与所述旁链路控制信息所在的资源组中的资源相对资源组的起始位置不同的资源组的资源组标识。
作为一个可选实施例，所述资源指示信息包括以下至少一项：
G-1项：所述资源指示信息中包括所述当前资源组对应的资源指示信息；其中，所述当前资源组为所述旁链路控制信息所在的资源组；例如，FRIV只指示其所在的资源组内的资源。
G-2项：所述资源指示信息中包括所述第一终端占用和/或预留的资源的资源指示信息；例如，一个FRIV指示终端在占用和/或预留的所有资源，或者多个FRIV一起指示终端在占用和/或预留的所有资源。
G-3项：所述资源指示信息中包括所述第一终端至少部分占用和/或预留的资源组对应的资源指示信息；
G-4项：第一终端占用和/或预留的资源不连续时，所述资源指示信息中包括所述当前资源组和至少部分所述其他资源组分别对应的资源指示信息。
在本申请实施例中，第一终端可以在资源组上发送旁链路控制信息，也可以在资源组集合上发送旁链路控制信息，其中，资源组集合为第一对象的资源组中的部分资源组，或指定资源组，或首要资源组(primary RB set)。
对于E-1项，第一终端在每个RB set上发送旁链路控制信息，以第一对象为PSSCH、第二对象为resource pool为了例，其中，旁链路控制信息包括资源指示信息FRIV和/或关联信息，满足以下内容的至少之一：
a)资源指示信息指示当前RB set上面的资源，或第一对象占据的所有RB set上面的资源：
i.例如，第一种情况为，在subchannel基于每个RB set进行编号时，第一终端在PSSCH所在的每个RB set上都独立发送FRIV，此FRIV只指示当前RB set的频域资源分配情况。除此之外，在subchannel基于resource pool进行编号时，终端也可以在PSSCH所在的每个RB set上发送FRIV，来指示当前RB set的频域资源分配情况。此时，接收端需要对每个RB set进行检测，来确定发送端所有的频域资源。
ii.第二种情况，在subchannel基于每个RB set进行编号时，或在subchannel基于resource pool编号而指示的频域资源是不连续的时候，第一终端在PSSCH所在的每个RB set上都发送FRIV，此FRIV指示当前PSSCH传输的所有频域资源分配情况。此时，要想指示所有频域资源，要么需要所有RB set上所有频域资源的分配情况都相同，这样就可以使用一个FRIV指示，否则每个RB set上都需要发送多个FRIV，来指示所有PSSCH上的资源分配情况。还有一种情况是，所有PSSCH上频域资源分配的subchannel size(子信道数目)相同，这样只需要额外指示多个FRIV的起始subchannel。此时，对接收端来说，当盲检到一个RB set上面的FRIV，即可跳过PSSCH占用的其他RB set来降低检测复杂度。接收端的盲检顺序可能是随机的，或是频域从低到高，或是频域从高到低， 或是从特定RB set或Primary RB set开始。
iii.第三种情况，在subchannel基于resource pool进行编号时，最简单的是PSSCH占用的频域资源在resource pool内是连续的，此时可以reuse R16/R17的资源指示方法，即只使用一个FRIV指示所有RB set上面的频域资源。此时，对接收端来说，需要盲检RB set内的SCI，直到检测到此FRIV。
b)其中，关联信息为N个RB set的标识，N为整数。(指示当前发送的TB/TBs所占据的其他N个RB set，可能是其余占据的部分RB set，也可能是全部)。
i.可选地，N个RB set是与发送指示信息与关联信息的RB set上频域分配资源相对位置相同/不同的RB set(接收端在检测关联信息后，可以跳过关联信息对应的RB set上面的盲检动作，降低检测复杂度)
1.当频域分配资源起始subchannel相同时，可以不发其他RB set的起始subchannel，或者发送且设置为一个特定的值/无效值。
ii.可选地，此N个RB set由网络预配置/配置/终端确定(接收端在检测此信息后，可以只在这些RB set上进行检测，降低检测复杂度)。
c)其中，关联信息除了可以为N个RB set的标识，也可以为bitmap(位图)
i.可选地，bitmap中每个bit按照预设顺序和RB set依次对应，例如，RB set的标识可以为bitmap中对应位置的比特1或比特0，或RB set index等。
d)指示信息指示的是除guard band以外的起始subchannel和subchannel size(假设此时guard band包括在subchannel内)。
对于E-2项，第一终端在RB set集合上发送指示信息(终端在有限的RB set上发送全部/部分RB set上的资源指示信息，例如，当只在一个RB set上发送所有RB set上的FRIV，如果各个RB set上起始subchannel的位置不同，则在需要在此RB set上指示出其他RB set上面的FRIV的起始subchannel，从而可以根据此指示计算出其他RB set的频域资源指示信息)：
a)其中，资源指示信息包括当前RB set上的频域资源指示信息，和/或其他全部/部分RB set上的资源指示信息
i.其中，资源指示信息包括起始subchannel和/或起始interlace,和/或subchannel和/或interlace的个数。
b)RB set集合为当前发送的TB/TBs所占据的所有RB set，或部分RB set，或特定RB set，和/或primary RB set(当资源指示信息只在部分RB set上指示时，接收端可能需要盲检SCI,宽带情况下复杂度较高，因此如果只在特定的RB set上，例如primary RB set上传输时，由于收发双发均知道primary RB set的位置，因此可以降低SCI检测复杂度)。
i.终端在RB set集合内，发送资源指示信息。
1.例如，终端在RB set集合内发送资源指示信息，其他RB set上不发送，且在RB se集合内的每个RB set上都发送PSSCH相关的资源指示信息。此时，如果终端的频域资源 包括RB set集合外的频域资源，则RB set集合内的RB set会发送多个FRIV，和/或关联信息来指示这些频域资源。对接收端来说，可以不对RB set集合以外的RB set进行检测，从而降低检测复杂度。
ii.其中，特定RB set或primary RB set由协议预定义/网络预配置/网络配置/终端确定。
1.例如，unicast(单播)的UE之间可以协商/配置1个或多个primary RB set。
iii.可选地，此N个RB set是与发送资源指示信息与关联信息的RB set上频域分配资源相对位置相同的RB set(接收端在检测关联信息后，跳过这些RB set上面的盲检动作，直接到对应的subchannel位置解码SCI，从而降低检测复杂度)。
1.可选地，此N个RB set由网络预配置/配置/终端确定(接收端在检测此信息后，只在这些RB set上进行检测，降低检测复杂度)。
作为一个可选实施例，
所述占用和/或预留的子信道位于一个所述资源组中；
或者，所述占用和/或预留的子信道位于多个所述资源组中。
在本申请实施例中，当1个interlace被定义在大于1个RB set的范围内时，假如配置为subchannel包括个1interlace或K个interlace，则：
1、可选地，终端指示的subchannel可以为interlace位于某个RB set上的部分(相当于允许终端只在RB set部分的资源上传输)；
2、可选地，终端指示的subchannel为某个RB set上的全部interlace(相当于终端interlace涉及到的RB sets上面要么使用全部的资源传输，要么不传输)。
在本申请实施例中，在第一终端占用和/或预留了多个所述资源组中的资源的情况下，保护频带的利用满足以下至少一项：
保护频带中被利用的资源由所述第一终端指示的资源确定；
保护频带中与所述第一终端占用和/或预留的资源中属于相同交错资源的资源可以被用于传输；
例如，当终端指示了多个资源组的资源，即占用或预留多个资源组的资源时，连续的资源组之间的保护频带也可以被认为用于了PSCCH/PSSCH传输，即保护频带是否被用于PSCCH/PSSCH由指示信息隐式指示，接收终端需要通过资源的指示信息判断保护频带是否被用于传输。由于保护频带包含属于多个interlace的PRB,所以一种情况是保护频带全部被用于传输，这种情况不再赘述。另一种情况是保护频带的部分被用于传输。例如，为了与终端指示的其他资源组上的资源保持一致，且便于多用户复用，保护频带上与这些资源中属于相同交错资源的资源可以被用于传输。比如终端指示了RB set 0和RB set 1中的sub-channel 0用于传输，而sub-channel 0对应于interlace 0和interlace 1。也就是说此时终端利用的资源都位于interlace 0和interlace 1上，则此时RB set 0和RB set 1之间的保护频带中同样也属于interlace 0和interlace 1的PRB资源可以被用于传输，而其他的PRB资源则不被用于传输。换一个说法，可以认为两个连续资源组之间的保护频 带也根据资源组中sub-channel与interlace的对应关系隐式映射到了对应的sub-channel上，当两个连续资源组上的某个sub-channel被指示占用和/或预留时，则终端认为此sub-channel上的属于保护频带的资源也被用于传输。
作为一个可选实施例，当所述资源指示信息的所述旁链路控制信息中包括所述当前资源组对应的资源指示信息时，所述旁链路控制信息包括第一节SCI和第二节SCI，第二节SCI的映射满足以下至少一项：
所述第二节SCI映射在对应的所述第一节SCI所在的资源组内；
所述第二节SCI在所述第一终端占用的资源上按照先频域后时域的规则进行映射。
具体地，在Sidelink中，PSSCH用于传输数据。PSSCH关联的控制信息分别携带在PSCCH和PSSCH的SCI中。其中，SCI分为两级，1st stage SCI(第一节SCI)在PSCCH中，2nd stage SCI(第二节SCI)在PSSCH中。
其中，在本申请实施例中，2nd SCI映射满足以下条件的至少之一：
a)当每个RB set上都独立传输SCI时，2nd SCI映射在对应的1st SCI所在的RB set内(好处是终端可以独立解码每个RB set)，或映射到PSSCH所占据的所有RB set内(相当于重用R16/R17的规则，开销较少，但是需要收到所有RB set才能解调，且此时需要依靠1st SCI携带ID等信息用于验证终端在哪些RB set上面发送了PSCCH和PSSCH)。
b)，当传输所占据的RB set集合上面只有一个SCI时，2nd SCI按照先频域后时域的规则映射，无论资源是否跨RB set,或者在对应的1st SCI所在的RB set内按照先频域后时域的规则映射。
作为一个可选实施例，所述第一终端发送旁链路控制信息，其中：
所述第二节SCI映射在保护频带上；
或者，所述第二节SCI不映射在保护频带上。
在本申请实施例中，当guard band用于PSSCH的传输时，2nd SCI可以映射在guard band上，或者2nd SCI不可以映射在guard band上。
在本申请实施例中，guard band的RB数量等于资源池/RB set内的interlace数量，在某些情况下保证subchannel的大小在有guard band的情况下也可以保持一致等等。
作为一个可选实施例，所述资源指示信息中预留资源的确定顺序包括以下至少一项：
随机确定；
频域和/或时域由高到低；
频域和/或时域由低到高；
优先指示所述资源指示信息所对应的资源组内的资源。
当然，除了上述预留资源的确定顺序之外，也可以根据其他方式作为预留资源的确定顺序，本申请实施例对此无需加以限制。
第二方面，参见图7所示，为本申请实施例所提供的另一种资源指示方法的实施流 程图，该方法可以包括以下步骤：
步骤701、网络侧设备根据子信道和/或资源组的编号规则向所述第一终端发送下行链路控制信息，其中，所述子信道和/或资源组的编号规则包括子信道和交错资源之间的映射规则，所述下行链路控制信息包括资源指示信息，所述资源指示信息用于指示所述第一终端用于发送占用和/或预留的资源；
步骤702、所述第一终端将所述资源指示信息承载于旁链路控制信息后发送至所述第二终端。
在本申请实施例中，资源指示信息既可以由第一终端发送，也可以由网络侧设备发送，具体地，网络侧设备可以根据子信道和/或资源组的编号规则，向第一终端发送下行链路控制信息(DCI，Downlink Control Information)，其中，下行链路控制信息中包括资源指示信息，基于资源指示信息可以指示第一终端在非授权频段的第一对象中占用或者预留的资源。第一终端在接收到资源指示信息后，还可以将资源指示信息承载于旁链路控制信息(SCI)后发送至第二终端，使得第二终端确定第一终端在非授权频段的第一对象中占用或者预留的资源。
作为另一种可选示例，网络侧设备可以根据子信道和/或资源组的编号规则，向第一终端和第二终端同时发送下行链路控制信息，使得第一终端和第二终端可以确定第一终端在非授权频段的第一对象中占用或者预留的资源。
由上述步骤701至702可知，本申请实施例预先配置子信道和/或资源组的编号规则，然后将子信道和/或资源组的编号规则用于在非授权频段上资源指示，其中，资源指示信息可以由网络侧设备发送给终端，例如可以发送给第一终端后第一终端再发送给第二终端，或者网络侧设备同时发送给第一终端和第二终端，使得网络侧设备可以根据子信道和/或资源组的编号规则来指示第一终端占用或者预留的资源，可以满足非授权频段上OCB等规则，且可以不改变Sidelink的已有框架，保证了资源的利用率，以及在不同场景下保证了收发两端的通信，以及如何进行资源指示和资源分配的问题，可以适应未来潜在的多样化应用场景和各种需求。
第三方面，参见图8所示，为本申请实施例所提供的又一种资源指示方法的实施流程图，该方法可以包括以下步骤：
步骤801、检测和/或接收所述第一终端发送的旁链路控制信息，和/或网络侧设备发送的下行链路控制信息，其中，所述旁链路控制信息和下行链路控制信息根据所述根据子信道和/或资源组的编号规则生成，所述子信道和/或资源组的编号规则包括子信道和交错资源之间的映射规则，所述旁链路控制信息包括资源指示信息，所述资源指示信息用于指示所述第一终端占用和/或预留的资源；
步骤802、根据所述资源指示信息，确定所述第一终端占用和/或预留的资源。
在本申请实施例中，第二终端作为接收端，可以检测和/或接收第一终端发送的旁链 路控制信息，和/或网络侧设备发送的下行链路控制信息，然后，可以从旁链路控制信息中提取出资源指示信息或者从下行链路控制信息提取出资源指示信息，其中，资源指示信息是第一终端或者网络侧设备根据子信道和/或资源组的编号规则生成的。第二终端获取到资源指示信息后，就可以确定第一终端在非授权频段的第一对象中占用或者预留的资源，其中，第二终端是可以根据子信道和/或资源组的编号规则来确定第一终端在非授权频段的第一对象中占用或者预留的资源，具体为第一终端在在非授权频段以子信道为单位的第一对象中占用或者预留的资源。
由上述步骤801至802可知，本申请实施例预先配置子信道和/或资源组的编号规则，然后将子信道和/或资源组的编号规则用于在非授权频段上资源指示，其中，当第二终端接收到第一终端或者网络侧设备发送的资源指示信息时，可以根据资源指示信息和子信道和/或资源组的编号规则来确定第一终端占用或者预留的资源，可以满足非授权频段上OCB等规则，且可以不改变Sidelink的已有框架，保证了资源的利用率，以及在不同场景下保证了收发两端的通信，以及如何进行资源指示和资源分配的问题，可以适应未来潜在的多样化应用场景和各种需求。

对于H-1项，若第一终端或者网络侧设备是在每个RB set上发送旁链路控制信息，且该旁链路控制信息中包括第一对象的X1个RB set的FRIV和N个RB set的资源组标识，则第二终端可以根据X1个RB set的FRIV，确定第一终端占用和/或预留的X1个RB set的资源，而当第二终端当盲检到一个RB set上面X1个RB set的FRIV，跳过第一对象的其他RB set的检测，从而降低检测复杂度。
对于H-2项，若第一终端或者网络侧设备是在每个RB set上发送旁链路控制信息，且该旁链路控制信息中包括第一对象的当前RB set的FRIV和N个RB set的资源组标识，则第二终端可以根据当前RB set的FRIV，确定第一终端占用和/或预留的当前RB set的资源，此时，第二终端可以继续检测N个RB set的资源组标识对应的资源组或者跳过N个RB set的资源组标识对应的资源组，从而跳过第一对象的某些RB set的检测，从而降低检测复杂度。
对于H-3项，若第一终端或者网络侧设备是在RB set集合上发送旁链路控制信息，且该旁链路控制信息中包括第一对象的X2个RB set集合的FRIV和N个RB set的资源组标识，则第二终端可以根据X2个RB set集合的FRIV，确定第一终端占用和/或预留的X2个RB set集合的资源，而当第二终端当盲检到一个RB set集合上面X2个RB set集合的FRIV，跳过第一对象的其他RB set集合的检测，从而降低检测复杂度。
对于H-2项，若第一终端或者网络侧设备是在每个RB set上发送旁链路控制信息，且该旁链路控制信息中包括第一对象的当前RB set集合的FRIV和N个RB set的资源组标识，则第二终端可以根据当前RB set的FRIV，确定第一终端占用和/或预留的当前RB set集合的资源，此时，第二终端可以继续检测N个RB set的资源组标识对应的资源组集合或者跳过N个RB set的资源组标识对应的资源组集合，从而跳过第一对象的某些RB set集合的检测，从而降低检测复杂度。
作为一个可选实施例，所述检测和/或接收所述第一终端和/或网络侧设备发送旁链路控制信息，包括以下至少一项：检测和/或接收所述关联信息中的资源组标识对应的资源组上的旁链路控制信息，或者，跳过检测和/或接收所述关联信息中的资源组标识对应的资源组上的旁链路控制信息。
在具体实现中，第二终端可以对每个资源组上的旁链路控制信息进行检测，从而得到资源指示信息，以根据资源指示信息确定第一终端占用或者和/或预留的资源。
在本申请实施例中，关联信息可以包括资源组标识，第二终端可以根据关联信息的资源组标识，对关联信息的资源组标识对应的资源组上的旁链路控制信息进行检测和/或接收，或者，跳过检测和/或接收关联信息的资源组标识对应的资源组上的旁链路控制信息，从而第二终端可以在传输所在的任意一个RB set或者RB set集合上检测到SCI即可停止检测其他SCI，降低盲检复杂度。
作为一个可选实施例，所述旁链路控制信息包括第一节SCI和第二节SCI，
在所述第一节SCI所在的资源组上检测和/或解码对应的所述第二节SCI；
或者，在所述第一终端占用或者预留的资源上检测和/或解码所述第二节SCI。
在本申请实施例中，第二终端只在第一节SCI所在的资源组内检测和/或解码对应的第二节SCI，或者，第二终端在发送端指示的资源上检测和/或解码第二节SCI。
作为一个可选实施例，
在保护频带上检测和/或解码所述第二节SCI；
或者，非保护频带上检测和/或解码所述第二节SCI。
在本申请实施例中，第二终端可以在保护频带上检测和/或解码第二节SCI，或者，可以不在保护频带上(非保护频带)检测和/或解码第二节SCI。
在具体实现中，以频域资源为例(当然也适用于时域资源等其他资源)，频域资源指示在不同的条件下有不同的方法。第一种方法是重用R16/R17的频域资源指示思想，即终端在PSCCH上发送FRIV，指示预留资源的起始subchannel与subchannel个数，如下图9A。这个方法开销较小，但是要求预留资源即使在跨RB set的情况下也需要频域连续，同时还要求所有终端都不是能力受限终端，即具备所有RB set上的SCI检测能力。因此，一种相对改进的方法是终端在PSSCH所在的每个RB set上都发送SCI，即都发送频域资源指示信息，如下图9B。在这种指示方法中，每个SCI指示的频域资源仍然都是PSSCH所占用的全部频域资源。
然而当终端在多个RB set上发送PSSCH/PSCCH时，假如subchannel和interlace都是在RB set内进行定义的，此时终端无法使用一个FRIV来指示多个RB set上面的资源分配情况，因为每个RB set上面的subchannel编号是独立的，如果仍然要指示PSSCH所占用的全部频域资源，就需要在SCI中发送多个FRIV，每一个FRIV对应一个RB set内的频域资源分配情况,如图9C所示。除此之外，如果各个RB set上起始subchannel的位置不同，则在需要在此RB set上指示出其他RB set上面的FRIV的起始subchannel，从而可以根据此指示计算出其他RB set的频域资源指示信息。毫无疑问，这种指示方法复杂度较高。因此，相对的，针对这个问题有两种改进方法，一种是终端在每个RB set上分别只指示此RB set上的资源分配情况，如图9D所示，或者在部分RB set上，指示全部RB set上的资源分配情况,如图9E所示。
如果是第一种情况，资源分配情况的指示较为简单。此时，按照此思想，第二节SCI也只会映射在独立的RB set上。由于在R16/R17中，第二节SCI是按照先频域后时域的方法进行映射，与RB set无关，因此，在SLU(Sidelink的非授权频段)下，可能需要修改2nd SCI的映射规则，第二节SCI在映射时，要考虑RB set的边界，即在RB set内按照先频域后时域的方法进行映射。
如果是第二种情况，资源分配的指示会更为复杂。第一种可能类似于上述第一种情况，终端在每个RB set上进行资源指示，但是会指示所有RB set上面的资源分配情况，或其他L个RB set上的资源分配情况，即图9C所示。在这种情况下，接收端可以在传 输所在的任意一个RB set上检测到SCI即可停止检测其他SCI，降低盲检复杂度。第二种可能是，终端只在部分RB set上发送资源指示信息，比如说只在一个RB set上，例如最低/最高/特定/primary RB set上发送，如图9E所示，或者在部分RB set上进行发送，同时在一些RB set上携带关联信息，第一关联指示用于指示其他N个RB set。此N个RB set是与发送资源指示信息与关联信息的RB set上频域分配资源相对位置相同的RB set。相对位置相同的意思是每个RB set内的频域资源的start subchannel都相同。当接收端在检测此信息后，就可以跳过这些RB set上面的盲检动作，降低检测复杂度，或者，此N个RB set由网络预配置/配置/终端确定，接收端在检测此信息后，只在这些RB set上进行检测，跳过其他RB set，降低检测复杂度。
本申请实施例，定义了在SLU场景下，终端只发送一个SCI时，或者，当终端在每个RB set内发送SCI时，如何指示不同RB set内的资源。同时还定义了SLU场景下subchannel与interlace的关系。
