Description

信息发送方法，通信节点及存储介质 技术领域
本申请涉及通信技术领域，例如涉及信息发送方法，通信节点及存储介质。
背景技术
第三代合作伙伴计划(3rd Generation Partnership Project，3GPP)系统设备在非授权频谱上发送数据前，首先需要根据业务优先级进行一定时长的信道侦听，在确定信道空闲的前提下才可以继续发送数据。如果基站以type1的信道接入方式成功接入信道，则可以认为基站初始化了一个信道占用时间(Channel Occupancy Time，COT)，在COT内基站和被基站调度的用户设备(User Equipment，UE)可以对信道进行连续占用。如果UE以type1的信道接入方式成功接入信道，则可以认为UE初始化了一个COT，在COT内UE和调度该UE的基站可以对信道进行连续占用。因此，在3GPP新无线电-未获授权的频谱(New Radio in Unlicensed Spectrum，NR-U)系统中，无论是基站还是UE，成功初始化了一个COT之后，通过调度，基站或者UE都能够在COT内进行连续的信道占用从而避免信道丢失。在版本18(又称R18)立项的非授权侧行链路(sidelink-unlicense，SL-U)系统支持UE和UE之间共享信道，然而，SL-U系统在一些场景下是分布式调度系统，当一个UE成功初始化了一个COT，其他UE需要共享这个COT时，如何保证COT内信道的持续占用是一个亟待解决的问题。

具体实施方式
此处所描述的具体实施例仅仅用以解释本申请，并不用于限定本申请。下文中将结合附图对本申请的实施例进行详细说明。
在非授权频谱上，可能存在非3GPP系统的设备(如蓝牙、Wi-Fi等)。当3GPP系统的设备需要在非授权频谱上工作时，为了和其他系统能够比较公平的共存，需要进行干扰避免技术，NR-U标准化了基站和UE在信道接入时的一些行为。例如，基站或者UE可以根据业务优先级使用type1的信道接入方式来进行数据发送前的信道侦听。图1示出了一种基站初始化COT的示意图。以基站为例，当基站成功接入信道后，就认为基站初始化(又可以理解为成功开始)了一个COT，COT有最大时间限制，在COT内基站和被基站调度的UE可以使用接入成功概率更大的type2的信道接入方式来接入信道。同理，图2示出了一种UE初始化COT的示意图。以UE为例，当UE成功接入信道后，就认为UE初始化了一个COT，在COT内UE和调度该UE的基站可以使用接入成功概率 更大的type2的信道接入方式来接入信道。
在COT内使用type2的信道接入方式接入信道需要遵循COT共享的一些限制。例如，当设备发送的数据与之前的数据传输之间的GAP(又可以理解为相邻两次数据传输之间的GAP)为25us时，设备在COT内可以使用type 2A的信道接入方式接入信道；当设备发送的数据与之前的数据传输之间的GAP为16us时，设备在COT内可以使用type 2B的信道接入方式接入信道；当设备发送的数据与之前的数据传输之间的GAP小于16us时，设备在COT内可以使用type 2C的信道接入方式接入信道；当设备发送的数据与之前的数据传输之间的GAP大于25us时，通常认为当前的COT可能会丢失，即信道会被其他非3GPP系统的设备抢占。
侧行链路(sidelink，SL)系统可以工作在集中式调度模式(mode1)，也可以工作在分布式调度模式(mode2)。在分布式调度模式下，没有类似基站这样的集中控制节点，每个UE都是自己确定的自己的数据的时频资源。当SL-U设备工作在非授权频谱，并且工作在mode2模式下时，UE和UE之间的传输的GAP是不可控的。因此当一个UE初始化了一个COT之后，在该COT内，其他UE的传输之间的GAP，或者其他UE和初始化UE的传输之间的GAP大于25us时，COT内的信道可能就会丢失，导致其他UE可能无法再继续共享该COT。
本申请提供的信息发送方法可以应用于各类无线通信系统中，例如长期演进(long term evolution，LTE)系统、第四代移动通信技术(4th-generation，4G)系统、第五代移动通信技术(5th-generation，5G)系统、LTE与5G混合架构系统、5G NR系统、以及未来通信发展中出现的新的通信系统，如第六代移动通信技术(6th-generation，6G)系统等。尤其适用于SL-U系统。图3示出了一实施例提供的一种无线通信系统的组网示意图。如图3所示，该无线通信系统包括终端设备110、接入网设备120和核心网设备130。
终端设备110可以是一种具有无线收发功能的设备，可以部署在陆地上(如室内或室外、手持、穿戴或车载等)；也可以部署在水面上(如轮船等)；还可以部署在空中(例如飞机、气球和卫星等)。一些终端设备110的举例为：UE、手机、移动台、平板电脑、笔记本电脑、超级移动个人计算机(Ultra-mobile Personal Computer，UMPC)、手持计算机、上网本、个人数字助理(Personal Digital Assistant，PDA)等可以联网的用户设备，或虚拟现实(Virtual Reality，VR)终端、增强现实(Augmented Reality，AR)终端、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)中的无线终端等，或物联网中的物联网节点，或车联网中的车载通信装置，或娱乐、游戏设备或系统，或全球定位系统设备等。本申请的实施例对终端设备110所采用的技术和设备形态不做限定，另外，终端设备110可以简称终端。
接入网设备120是终端设备110通过无线方式接入到该无线通信系统中的接入设备，可以是基站(base station)、长期演进增强(Long Term Evolutionadvanced，LTEA)中的演进型基站(evolved NodeB，eNB或eNodeB)、发送接收点(transmission reception point，TRP)、5G移动通信系统中的基站或gNB、未来移动通信系统中的基站或无线保真(Wireless Fidelity，WiFi)系统中的接入节点等。基站可以包括各种宏基站、微基站、家庭基站、无线拉远、路由器、WIFI设备或者主小区(primary cell)和协作小区(secondary cell)等各种网络侧设备、定位管理功能(location management function，LMF)设备。也可以是完成基站部分功能的模块或单元，例如，可以是集中式单元(central unit，CU)，也可以是分布式单元(distributed unit，DU)。本申请的实施例对接入网设备120所采用的技术和设备形态不做限定，另外，接入网设备120可以简称基站。
核心网设备130可以包括接入与移动性管理网元和会话管理网元。示例性地，终端设备110可以通过接入网设备120接入核心网，从而实现数据传输。
在本申请实施例中，提供一种可运行于上述无线通信系统的信息发送方法，通信节点及存储介质，能够保证UE在初始化的COT内，任意传输之间不会出现大于一个时隙(slot)时长的GAP，从而保证COT内信道的持续占用。
首先，对本申请下述实施例涉及的概念进行解释：
在本申请实施例中，频域上，SL UE可以根据配置的信息确定工作载波，在工作载波上确定工作带宽部分(Bandwidth Part，BWP)，在BWP内确定通信资源池。通信资源池包括发送资源池和接收资源池。通常，非授权载波上的SL通信资源池包括整数个资源块集合(Resource Block set，RB set)，一个RB set指一个先听后发(Listen Before Talk，LBT)带宽范围，一个RB set由若干个连续的资源块(Resource Block，RB)组成。图4示出了一实施例提供的一种SL通信资源池的示意图。如图4所示，SL载波包括N+1个RB set，SL通信资源池包括3个连续的RB set，分别为RB set1、RB set2和RB set3。
在本申请实施例中，时域上，SL UE在工作载波的所有物理时隙中，根据配置的信息确定通信资源池上的可用时隙，称为SL逻辑时隙。一个SL逻辑时隙最多包含连续14个符号，SL逻辑时隙分为两种结构：图5示出了一实施例提供的一种SL逻辑时隙的结构示意图；图6示出了一实施例提供的另一种SL逻 辑时隙的结构示意图。其中，一个自动增益控制(Automatic Gain Control，AGC)符号占用一个符号，一个空符号(GAP符号)占用一个符号，一个物理边链路反馈资源(Physical Sidelink Feedback Channel，PSFCH)符号占用一个符号。如图5所示，SL逻辑时隙不包括PSFCH符号，物理边链路控制信道(Physical Sidelink Control Channel，PSCCH)符号/物理边链路共享信道(Physical Sidelink Shared Channel，PSSCH)符号最多占用12个符号；同理，如图6所示，SL逻辑时隙包括PSFCH符号，PSCCH符号/PSSCH符号最多占用9个符号。
在本申请实施例中，配置资源位置/信息的方法可以为：通过信令的方式由网络或基站发送给UE，即由网络或基站将资源位置/信息配置给UE；或者，由其他高层实体(如UE自身的高层、其他网络实体等)为UE提供资源位置/信息，即由其他高层实体将资源位置/信息预配置给UE。在本申请下述实施例中，配置资源位置/信息也包括预配置资源位置/信息的情况，并且后续将以高层实体代指基站，网络或其他高层实体。
下面，对信息发送方法，通信节点及其技术效果进行描述。
图7示出了一实施例提供的一种信息发送方法的流程示意图，如图7所示，本实施例提供的方法适用于第一通信节点。在本示例中，第一通信节点(也可以称为第一通信节点设备或者第一节点)为初始化COT的UE，第二通信节点(也可以称为第二通信节点设备或者第二节点)为除了初始化COT的UE以外的其他UE。下述实施例中将第一通信节点记为UE1，将第二通信节点记为UE2。该方法包括如下操作。
S110、配置资源池的每个资源块集合RB set内的预设资源位置，预设资源位置包括第一信息的频域资源位置，第一信息包括占用信号和占用信道中的至少一项。
当UE1以第一信道接入类型(type1)成功接入信道后，UE1可以发送自己的数据，并将COT共享信息(即COT的相关信息)发送给UE2，以使得UE2根据接收到的COT共享信息判断是否使用该COT，若UE2使用该COT，则UE2在发送自己的数据之前，首先从第一信道接入类型切换到接入信道成功概率更高的第二信道接入类型(type2)，但是切换为第二信道接入类型的前提是传输之间的gap不能大于25us。
另外，UE1如果工作在集中式调度模式(mode1)下，Uu链路是在授权频谱上的，因此基站本身是没有非授权频谱上的信道占用信息的，基站也并不能保证UE之间的传输一定是时域连续的；UE1如果工作在分布式调度模式(mode2) 下，UE1的资源都是自己确定的，更加难以保证UE之间的传输是时域连续的。
因此，本申请为了保证信道的持续占用，采用UE1在COT内的信道空闲slot或者slot内的空闲符号上发送第一信息的方式，保证UE1分享的COT内的信道的持续占用，也有利于UE2共享COT信息。
基于上述描述，本申请为了避免第一信息干扰其他信息的传输，同时也为了节省开销，在资源池的每个RB set内配置了预设资源位置。预设资源位置是针对资源池内的每个RB set配置的，因此，预设资源位置包括第一信息的频域资源位置，预设资源位置适用于所有时域，第一信息包括占用信号和占用信道中的至少一项。
图8示出了一实施例提供的一种资源池的每个RB set内的预设资源位置的示意图。如图8所示，资源池包括两个RB set，分别为RB set0和RB set1，每个RB set内配置了第一信息的预设资源位置，预设资源位置适用于所有时域(即slot n，slot n+1，slot n+2，slot n+3，slot n+4等等)。
在一实施例中，对于每个RB set，预设资源位置在该RB set内采用位图(bitmap)指示。
在一种示例中，bitmap与该RB set内的RB一一对应；bitmap中的1表示该RB为预设资源位置，bitmap中的0表示该RB不为预设资源位置。
在另一种示例中，bitmap与该RB set内的交织一一对应；bitmap中的1表示该交织为预设资源位置，bitmap中的0表示该交织不为预设资源位置。
在时域上，预设资源位置通常位于slot内的PSCCH/PSSCH所在的符号上，或者位于slot内的PSFCH所在的符号上，或者位于slot内的GAP符号上。
S120、确定第一资源，第一资源包括用于发送第一信息的候选时域资源和候选RB set。
在一实施例中，候选时域资源包括第一通信节点以第一信道接入类型进行信道侦听获得的信道占用时间COT内的以下资源中的至少之一：
所有时隙，部分时隙，时隙内的物理边链路控制信道PSCCH符号，时隙内的物理边链路共享信道PSSCH符号，时隙内的物理边链路反馈信道PSFCH符号，时隙内的GAP符号。
在一实施例中，候选RB set包括第一通信节点以第一信道接入类型或者第二信道接入类型中的至少之一进行信道侦听获得的信道的至少一个RB set。
图9示出了一实施例提供的一种第一资源的示意图。如图9所示，UE1以第一信道接入类型进行信道侦听获得的COT对应6个slot，UE1以第一信道接 入类型或者第二信道接入类型中的至少之一进行信道侦听获得的信道对应2个RB set，6个slot分别为slot n，slot n+1，slot n+2，slot n+3，slot n+4和slot n+5，2个RB set分别为RB set0和RB set1。假设候选时域资源为UE1以第一信道接入类型进行信道侦听获得的COT内的所有时隙，候选RB set为UE1以第一信道接入类型或者第二信道接入类型中的至少之一进行信道侦听获得的信道的所有RB set，那么，在时频域上，第一资源对应图9所示的12个预设资源位置，即图9所示的12个预设资源位置处的资源可以作为发送第一信息的候选资源。
S130、根据第一资源，确定第二资源，并在第二资源的预设资源位置上发送第一信息。
在一实施例中，UE1在第二资源的预设资源位置上发送第一信息前，还可以使用第二信道接入类型(type2)进行信道侦听。
第二资源可以理解为第一资源的全集或者子集。在一实施例中，“根据第一资源，确定第二资源”可以包括如下两种方式中的任意一种：
方式一：采用先时域后频域的确定方式。

a2、根据候选RB set中的所有RB set的时域资源结果，确定第二资源。
在a2中，根据候选RB set中的所有RB set的时域资源结果，确定第二资源的规则可以为：若第一通信节点需要在候选RB set中的所有RB set中的任一RB set的目标时域位置接收第三信息，则第一通信节点在候选RB set中的所有RB set的目标时域位置均不发送第一信息，第三信息包括SL信号、SL信道、NR下行信号、NR下行信道、NR上行信号、NR上行信道中的至少一项。
继续以图9所示的第一资源为例，假设RB set0的时域资源结果包括slot n、slot n+1和slot n+3，RB set1的时域资源结果包括slot n和slot n+1。如果UE1需要在RB set1的slot n+3接收第三信息，那么UE1在所有RB set的slot n+3均不发送第一信息。因此，基于RB set0的时域资源结果和RB set1的时域资源结果，最终确定的第二资源是RB set0的slot n、slot n+1，RB set1的slot n、slot n+1。即，UE1在RB set0的slot n、slot n+1，RB set1的slot n、slot n+1的预设资源位 置上发送第一信息。
在一实施例中，时域资源结果满足以下五个条件中的至少之一：

条件a3：时域资源结果不包括第五资源，第五资源为资源占用信息对应的资源，资源占用信息携带在第二通信节点在反馈资源上发送的反馈信息中。
在条件a3的基础上，可选的，反馈信息所在的反馈资源上的RSRP大于或者等于第二预设阈值。即，只有在反馈信息所在的反馈资源上的RSRP大于或者等于第二预设阈值时，时域资源结果才不包括第五资源；反之，时域资源结果可以包括第五资源。
在一实施例中，每个RB set或者每个资源池配置反馈资源的时域信息和频域信息中的至少一项；反馈资源的时域信息包括周期N、周期内的时隙偏移(offset)为k、时隙内的符号位置中的至少一项；反馈资源与反馈资源所在时隙之后的时隙索引对应，对应关系根据相对时隙索引和时隙内的反馈资源位置 确定；或者，反馈资源与反馈资源所在时隙之后的候选信道资源索引对应，对应关系根据相对候选信道资源时频索引和时隙内的反馈资源位置确定。
候选信道可以为PSCCH/PSSCH信道。
条件a4：时域资源结果不包括第六资源，第六资源为第一通信节点需要在第二资源上接收第三信息的资源，第三信息包括SL信号、SL信道、NR下行信号、NR下行信道、NR上行信号、NR上行信道中的至少一项。

以图9所示的第一资源为例，候选时域资源包括6个slot，分别为slot n，slot n+1，slot n+2，slot n+3，slot n+4和slot n+5，依次确定每个时域资源的频域资源结果。假设slot n的频域资源结果包括RB set0，slot n+1的频域资源结果为空，slot n+2的频域资源结果为空，slot n+3的频域资源结果为空，slot n+4的频域资源结果包括RB set0，slot n+5的频域资源结果包括RB set1，因此，最终确定的第二资源是slot n的RB set0，slot n+4的RB set0和slot n+5的RB set1。即，在slot n的RB set0，slot n+4的RB set0和slot n+5的RB set1的预设资源位置上发送第一信息。
在一实施例中，频域资源结果满足以下四个条件中的至少之一：

下面，罗列一些示例性实施方式，用于解释说明本申请上述实施例中时域资源结果满足的五个条件，下述示例性实施方式可以单一执行，也可以组合执行。另外，本申请上述实施例中频域资源结果满足的四个条件与下述实施例类似，为了简洁，此处不再赘述。
在第一个示例性实施方式中，图10示出了一实施例提供的一种时域资源结果的示意图。如图10所示，假设UE1以第一信道接入类型进行信道侦听获得的COT对应6个slot，UE1以第一信道接入类型或者第二信道接入类型中的至少之一进行信道侦听获得的信道对应2个RB set，6个slot分别为slot n，slot n+1，slot n+2，slot n+3，slot n+4和slot n+5，2个RB set分别为RB set0和RB set1。
由于UE1在RB set0的slot n和slot n+2上发送第二信息、在RB set1的slot n和slot n+2上发送第二信息，为了保证COT内信道的持续占用，在RB set0上，UE1在COT内的6个slot上的slot n+1，slot n+3，slot n+4，slot n+5这4个slot的预设资源位置上发送第一信息，在slot n和slot n+2的预设资源位置上不需要发送第一信息；同理，在RBset1上，UE1在COT内的6个slot上的slot n+1，slot n+3，slot n+4，slot n+5这4个slot的预设资源位置上发送第一信息，在slot n和slot n+2的预设资源位置上不需要发送第一信息。
在第二个示例性实施方式中，图11示出了一实施例提供的另一种时域资源结果的示意图。如图11所示，假设UE1以第一信道接入类型进行信道侦听获得的COT对应6个slot，UE1以第一信道接入类型或者第二信道接入类型中的至少之一进行信道侦听获得的信道对应2个RB set，6个slot分别为slot n，slot n+1，slot n+2，slot n+3，slot n+4和slot n+5，2个RB set分别为RB set0和RB set1。
对于RB set0，UE1根据时刻n之前的检测结果，确定UE2在slot n+4上有数据传输(即slot n+4被UE2预留)，并且UE1在RB set0的slot n上发送第二信息；对于RB set1，UE1根据时刻n之前的检测结果，确定UE2在slot n+2上有数据传输(即slot n+2被UE2预留)，并且UE1在RB set1的slot n上发送第二信息。
因此，在RBset0上，UE1在COT内的6个slot上的slot n+1，slot n+2，slot n+3，slot n+5这4个slot的预设资源位置上发送第一信息，在slot n和slot n+4的预设资源位置上不需要发送第一信息；同理，在RBset1上，UE1在COT内的6个slot上的slot n+1，slot n+3，slot n+4，slot n+5这4个slot的预设资源位置上发送第一信息，在slot n和slot n+2的预设资源位置上不需要发送第一信息。
如果RBset1的slot n+2在PSCCH或者PSSCH上的DMRS的RSRP小于第一预设阈值，那么，UE1仍旧需要在RBset1的slot n+2的预设资源位置上发送第一信息。
在第三个示例性实施方式中，图12示出了一实施例提供的又一种时域资源结果的示意图。如图12所示，假设反馈资源PSFCH的周期为2，对应PSFCH之后的2个连续slot。
UE1发送了COT共享信息后，如果有三个UE2要使用该COT，这三个UE2分别记为UE2a、UE2b和UE2c，那么UE2a、UE2b和UE2c分别在时隙对应的反馈资源(如PSFCH资源)上发送反馈信息，UE1在slot n+1和slot n+3上根据PSFCH反馈资源上的接收信息，确认了在slot n+2，slot n+3和slot n+5上分别有UE发射数据，那么UE1只需要在COT内的slot n+4的预设资源位置上发送第一信息，slot n+2，slot n+3和slot n+5的预设资源位置上不需要发送第一信 息，slot n和slot n+1由于UE1上发送了第二信息，因此也不需要发送第一信息。
如果slot n+2对应的反馈信息所在的反馈资源上的RSRP小于第二预设阈值，那么，UE1仍旧需要在slot n+2的预设资源位置上发送第一信息。
在第四个示例性实施方式中，参考图10，假设UE1以第一信道接入类型进行信道侦听获得的COT对应6个slot，UE1以第一信道接入类型或者第二信道接入类型中的至少之一进行信道侦听获得的信道对应2个RB set，6个slot分别为slot n，slot n+1，slot n+2，slot n+3，slot n+4和slot n+5，2个RB set分别为RB set0和RB set1。
由于UE1在RB set0的slot n和slot n+2上发送第二信息、在RB set1的slot n和slot n+2上接收第三信息，为了保证COT内信道的持续占用，在RBset0上，UE1在COT内的6个slot上的slot n+1，slot n+3，slot n+4，slot n+5这4个slot的预设资源位置上发送第一信息，在slot n和slot n+2的预设资源位置上不需要发送第一信息；同理，在RBset1上，UE1在COT内的6个slot上的slot n+1，slot n+3，slot n+4，slot n+5这4个slot的预设资源位置上发送第一信息，在slot n和slot n+2的预设资源位置上不需要发送第一信息。
在第五个示例性实施方式中，图13示出了一实施例提供的再一种时域资源结果的示意图。如图13所示，UE1在slot n初始化COT成功，并在slot n上发送第二信息，在slot n之前，确定了与slot n的数据相同的RB set下，slot n+2和slot n+4上有数据传输，那么UE1确定了COT内slot 4为最后一个传输slot，那么UE1在slot n+1和slot n+3这2个slot的预设资源位置上发送第一信息，在slot n+2，slot n+4，slot n+5的预设资源位置上均不用发送第一信息。slot n由于UE1上发送了第二信息，因此也不需要发送第一信息。
在本申请中，当UE1发送了第一信号之后，为了不影响block其他不共享该UE1COT的UE正常发射数据，可以认为3GPP系统内UE之间的第一信息不影响UE的LBT。
图14示出了一实施例提供的一种信息发送装置的结构示意图，该装置可以配置于通信节点中，如图14所示，该装置包括：配置模块10、确定模块11和发送模块12。
