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所获得的所有其他实施例,都属于本申请保护的范围。
1、先听后发(Listen Before Talk,LBT)
目标,在NR系统中,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。
为了与NR系统部署保持一致,并尽可能的最大化基于NR的非授权接入,非授权频段可以工作在5吉赫兹GHz、37GHz以及60GHz频段。
非授权频段的大带宽(80或者100兆赫兹MHz)能够减小基站和终端的实施复杂度。由于非授权频段由多种技术共用,因此在某些国家或者区域,非授权频段在使用时必须符 合规定regulation以保证所有终端可以使用该资源,例如LBT,最大信道占用时间(Maximum Channel Occupancy Time,MCOT)等规则。当传输节点需要发送信息时,需要先做LBT,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,则认为信道为繁忙,传输节点不能进行发送。在传输节点开始传输后,占用的信道时间(Channel Occupancy Time,COT)不能超过MCOT。此外,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。
其中,传输节点可以是基站,终端等等。
通常,常用的LBT的类型(Type)可以分为Type1,Type2A,Type2B和Type2C。
其中,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 LBT是发送节点不做LBT。
Type2A LBT和Type2B LBT是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 LBT是在25微秒us内做LBT,适用于在共享COT时,两个传输之间的gap大于等于25us。而Type2B LBT是在16us内做LBT,适用于在共享COT时,两个传输之间的间隔gap等于16us。
2、非授权频谱的新空口(NR inUnlicensed Spectrum,NRU)的wideband信道接入
目前,在NRU中的wideband信道接入分为下行链路(Down Link,DL)信道接入和上行链路(Up Link,UL)信道接入。
其中,DL信道接入包括TypeA和TypeB两种机制。
Type A机制是基站在每个信道channel上进行Type 1DL的信道接入,且如果基站在这个频带上没有配置保护频带guard band,且一旦基站在任一个channel上信道接入失败,则基站不能在该任一个channel上进行传输。而guard band的配置方式由a-1个guard band的起始物理资源块(Physical Resource Block,PRB)和PRB尺寸size指示组成,其中,a为RB set的个数,因此频带上guard band的个数为a-1,a为正整数。
Type B机制是基站在wideband中的channel中选择一个主信道(primary channel)进行Type 1DL的信道接入,而其他的辅信道(secondary channel)上可以只做一次Type 2DL的信道接入。
3、wideband
通常,wideband是相对于非授权频段上的信道接入单位定义的,该非授权频段上的信道接入单位为20兆赫兹MHz的channel(即RB set),因此当终端选择多个channel进行信道接入,即进行wideband传输,每个channel上分别传输待传输的信息中的一部分信息。此时,wideband在频域上不一定连续,即终端选择的wideband可能是由频域连续的channel组成的,也可能是非频域连续的channel组成的。
4、信道占用时间(Channel Occupancy Time,COT)
通常,网络侧设备(例如基站)可以根据基站的下行链路(Down Link,DL)信道接入,或终端上行链路(Up Link,UL)信道接入,发起信道占用(Channel Occupancy,CO),从而基站(或终端)可以根据信道接入优先级类别(Channel Access Priority Class,CAPC),确定该信道接入的最大COT,进而基站(或终端)可以在该最大COT内,占用信道进行信 息传输。
5、能力受限终端
通常,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的终端(如只支持20MHz带宽的终端),或其他能力(例如解调能力等)存在上限的终端。
假设终端只支持20MHz带宽的终端,此时,如果该终端在工作在配置了较大带宽(例如80MHz)的频段或资源池上时,只能对其中的20MHz进行检测,解调等。
6、其他术语

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数据传输方法、装置、终端及介质进行详细地说明。
在相关技术中,在非授权频段上,若终端需要传输数据,则终端需要先执行LBT,并在执行LBT成功的情况下,再传输该数据。若终端需要传输的数据的数据包较大,则终端需要在多个信道上进行宽带wideband传输,以传输该数据。但是,在相关技术中,旁链路技术尚未定义终端如何进行wideband传输,因此,可能导致终端无法传输数据包较大的数据,如此,导致终端的通信性能较差。
为了解决上述技术问题,本申请实施例提供了一种数据传输方法。图2示出了本申请实施例提供的一种数据传输方法的流程图。如图2所示,本申请实施例提供的数据传输方法可以包括下述的步骤101和步骤102。
步骤101、终端确定是否满足第一条件。
可选地,本申请实施例中,在终端确定要传输数据的情况下,终端可以确定是否满足第一条件。
可选地,本申请实施例中,上述第一条件具体可以为以下任一项:协议预定义的条件、网络侧设备配置的条件、网络侧设备预配置的条件。
可选地,本申请实施例中,上述第一条件包括以下至少一项:
第一数量大于第一门限;
第二数量大于预定数量;
第一测量值小于第二门限;
第一测量值大于第三门限;
终端的媒体接入控制(Media Access Control,MAC)层选择的候选资源满足第二条件;
第一次数小于第四门限;
在选择的信道上全部执行LBT成功;
在选择的信道中的至少两个信道上执行LBT成功;
目标对象的剩余数据包时延预算(Packet Delay Budget,PDB)小于第五门限。
本申请实施例中,上述第一数量包括以下至少一项:目标对象携带的信息的数据量、目标对象携带的信息的数量、目标对象的TB数量、目标对象的信息量、MAC协议数据单元(Protocol Data Unit,PDU)的数量、MAC PDU携带信息的数量、旁链路共享信道的数据量、旁链路广播信道的数据量。
其中,目标对象携带的信息可以理解为:终端缓存的信息,和/或,终端待发送的信息。
其中,上述MAC PDU具体可以为:目标对象所对应的MAC PDU;上述旁链路共享信道具体可以为:传输目标对象的逻辑信道;上述、旁链路广播信道具体可以为:传输目标对象的逻辑信道。
可选地,本申请实施例中,上述第一门限(和/或下述实施例中的门限)可以包括以下至少一项:协议预定义的门限、网络侧设备预配置的门限、网络侧设备配置的门限、终端确定的门限。
示例性地,终端的MAC层(或更高层)可以根据到达的数据包的大小(或MAC PDU的大小、或共享信道中要发送数据的大小是否大于设定的门限),确定终端更否适合采用宽带传输的方式进行传输,从而在确定适合采用宽带传输的方式进行传输的情况下,可以触发终端进行宽带传输。
本申请实施例中,上述第二数量为:终端的MAC层选择的资源单位的数量;上述预定数量为:第一资源块(Resource Block,RB)集合set内的资源单位的数量。
其中,上述资源单位可以包括以下至少一项:子信道subchannel、交织块interlace。
上述第一RB set具体可以为终端选择的候选资源集中的任一个RB set或特定的RB set。其中,该特定的RB set可以包括以下至少一项:协议预定义的RB set、网络侧设备配置的RB set、网络侧设备预配置的RB set、终端选择的RB set。
这里,候选资源集中可以包括以下至少一项:时域资源、RB set、候选资源(频域资源)等。
示例性地,在终端的MAC层(或更高层)可以根据第一数量确定终端进行传输需要的RB set数量大于1(或者子信道的数量大于一个RB set内包含的数量)时,终端可以采用宽带传输的方式进行传输。
本申请实施例中,上述第一测量值为:终端对第一对象进行测量的测量值;该第一对象包括以下至少一项:资源池、载波、信道集、信道。
其中,第一测量值可以包括以下至少一项:信道忙比(Channel Busy Ratio,CBR)、信道占用率(Channel occupancy Ratio,CR)、LBT成功率、LBT失败率、传输成功率、传输失败率、混合自动重传请求(Hybrid Automatic Repeat Request,HARQ)-确认ACK率、HARQ-否认NACK率。
这里,在第一测量值包括CBR、CR、LBT失败率、传输失败率、HARQ-NACK率的情况下,第一条件包括第一测量值小于第二门限;在第一测量值包括LBT成功率、传输成功率、HARQ-ACK率的情况下,第一条件包括第一测量值大于第三门限。
示例性地,终端的MAC层(或更高层)在确定是否采用宽带传输的方式进行传输时,还可以考虑信道条件(或者说通信条件)。例如,终端可以测量至少部分信道上面的CBR,当CBR小于设定的门限时,终端可以认为此时通信条件较高,且LBT成功率较高,从而终端就可以采用宽带传输的方式进行传输。同样的,终端还可以根据统计的LBT成功率(和/或传输成功率等)确定是否采用宽带传输的方式进行传输。
可选地,本申请实施例中,上述终端的MAC层选择的候选资源满足第二条件,包括以下至少一项:
终端的MAC层选择的候选资源位于特定的RB set上;
终端的MAC层选择的候选资源位于多个RB set上。
本申请实施例中,上述特定的RB set包括以下至少一项:协议预定义的RB set、网络侧设备预配置的RB set、网络侧设备配置的RB set、终端确定的RB set。
需要说明的是,此时终端的MAC层选择的候选资源是可能用于传输的资源,包含多个候选资源或候选资源组合。
本申请实施例中,在特定颗粒度下,由终端的MAC层选择候选资源时,才确定是否进行宽带传输。
其中,特定颗粒度可以包括以下至少一项:协议预定义的颗粒度、网络侧设备预配置的颗粒度、网络侧设备配置的颗粒度。
可以理解,在颗粒度为RB set时,当终端的物理层基于每个RB set进行资源选择时,终端的物理层可能不需要知道终端的MAC层(或更高层)是否触发了宽带传输,而终端的MAC层(或更高层)可能也仅仅根据第一数量确定倾向于进行宽带传输,且是否最终进行宽带传输需要根据终端的物理层上报的候选资源集进行确定。此时,假如终端的物理层上报的候选资源集中没有可以进行宽带传输的资源或资源组合,那么终端的MAC层最终就可能只可以选择单信道传输。反之,终端的MAC层从候选资源集中选择了多个候选资源作为传输资源,且这些资源在时域上占据了多个RB set,就相当于终端的MAC层触发了宽带传输,即终端可以采用宽带传输的方式进行传输。
本申请实施例中,上述第一次数包括以下至少一项:终端因执行LBT失败而取消传输的次数、终端连续因执行LBT失败而取消传输的次数。
可以理解,宽带传输可能需要在多个信道上LBT成功才可以执行传输,甚至,需要在选择的所有信道上LBT成功才可以传输,因此,一旦有任意一个信道上LBT失败就会造成传输取消。可以推算的是,在此背景下,相对于只需要一个信道上LBT成功的单信道传输,宽带传输的可能性会大大降低。因此,如果终端在一个数据包的传输过程中,或者一段时间内,如果因LBT失败而取消宽带传输的行为达到了一定次数,则在下一次传输时不再选择宽带传输,避免再一次执行宽带传输失败,而导致传输时延增加,甚至通信可靠性降低的问题。
可选地,本申请实施例中,当终端传输下一个数据包时,或第一测量值小于/大于一定门限时,或终端采取了一次单信道传输后,可以重新允许宽带传输,重新计算因LBT失败而取消宽带传输的次数,和或重启定时器等。
可选地,本申请实施例中,当终端选择的信道全部LBT成功后,终端可以执行宽带传输。
可以理解,当协议预定义或网络预配置终端只能在选择的信道全部LBT成功后,才可以执行宽带传输。
可选地,本申请实施例中,当终端选择的信道其中至少两个信道LBT成功后,终端可以执行宽带传输。
可以理解,如果终端采用的是先LBT再资源选择的方式,那么终端必须在选择的信道全部成功或部分成功后,才可以执行宽带传输。
步骤102、在终端确定满足第一条件的情况下,终端采用宽带传输的方式传输目标对象。
本申请实施例中,上述目标对象包括以下至少一项:传输块(Transmission Block,TB)、物理旁链路控制信道(Physical Sidelink Control Channel,PSCCH)、物理旁链路共享信道(Physical Sidelink Shared Channel,PSSCH)、物理旁链路反馈信道(Physical Sidelink Feedback Channel,PSFCH)、旁链路同步信号块(Sidelink Synchronization Signal Block,S-SSB)、参考信号。
需要说明的是,本申请实施例中,宽带传输还可以表达为多信道传输。
可选地,本申请实施例中,终端可以在至少两个信道上,分别传输目标对象的部分信息,以采用宽带传输的方式传输目标对象;或者,终端可以在至少两个信道中的每个信道 上,分别传输目标对象,采用宽带传输的方式传输目标对象。
以终端在每个信道上分别传输目标对象为例:
可选地,本申请实施例中,结合图2,如图3所示,上述步骤102具体可以通过下述的步骤102a实现。
步骤102a、在终端确定满足第一条件的情况下,终端在K个信道中的每个信道上,分别传输目标对象。
本申请实施例中,K为大于1的正整数。
可以理解,终端可以在K个信道中的每个信道上,分别传输一次目标对象,即终端可以重复传输K次目标对象。
可以理解,终端重复传输K次目标对象,会增强接收端成功接收及解码的可能,降低终端需要重传的可能性,从而避免终端需要再一次执行信道接入而进行重传。
可选地,本申请实施例中,K是根据终端执行LBT成功的情况确定的。
其中,终端执行LBT成功的次数越大,则K可以越大,终端执行LBT成功的次数越小,则K可以越小。或者,终端执行LBT成功的次数越大,则K可以越小,终端执行LBT成功的次数越小,则K可以越大。
可选地,本申请实施例中,在终端确定不满足第一条件的情况下,终端可以执行第二操作。其中,该第二操作可以为以下任一项:
采用单信道传输的方式传输目标对象;
下述实施例中的第一操作。
需要说明的是,针对单信道传输的方式的说明,可以参考相关技术中的具体描述,本申请实施例在此不再赘述。
以下将针对终端确定不满足第一条件的场景,进行具体举例说明。
可选地,本申请实施例中,数据传输方法还可以包括下述的步骤201。
步骤201、在终端确定不满足第七条件的情况下,终端执行第一操作。
可选地,本申请实施例中,上述第七条件包括以下至少一项:
第一条件;
第五候选资源包含的资源单位的数量小于第十八门限;
第六候选资源包含的资源单位的数量小于第十九门限。
本申请实施例中,上述第五候选资源包括以下至少一项:第二候选资源集中的对应的同一个时间单元的候选资源、第二候选资源集中的全部候选资源。
其中,上述时间单元可以为以下任一项:符号、时隙、微时隙、子帧、帧等。
上述第二候选资源集具体可以为以下任一项:终端的物理层上报至终端的MAC层的候选资源集、特定的候选资源集。其中,该特定的候选资源集可以包括以下至少一项:协议预定义的候选资源集、网络侧设备预配置的候选资源集、网络侧设备配置的候选资源集、终端确定的候选资源集。
上述第二候选资源集中的对应的同一个时间单元的候选资源可以理解为:第二候选资源集中的每一个时间单元内的所有候选资源。
本申请实施例中,上述第六候选资源包括以下至少一项:第二候选资源集中的对应第二占比的时间单元的候选资源、第二候选资源集中的全部候选资源。
其中,上述第二候选资源集中的对应第二占比的时间单元的候选资源可以理解为:第二候选资源集中第二占比(例如X%,X为正整数)的时间单元内的所有候选资源。
可选地,本申请实施例中,上述第十八门限可以包括以下至少一项:协议预定义的门限、网络侧设备预配置的门限、网络侧设备配置的门限、终端确定的门限。上述第十九门限可以包括以下至少一项:协议预定义的门限、网络侧设备预配置的门限、网络侧设备配置的门限、终端确定的门限。
可以理解,当终端的物理层上报的候选资源集中的候选资源无法支持终端采用宽带传输的方式进行传输时,终端不采用宽带传输的方式进行传输。
本申请实施例中,上述第一操作包括以下至少一项:
拆分目标对象;
采用单信道传输;
触发终端进行资源选择;
触发终端进行资源重选;
重新获取第一配置参数;
重新配置第一配置参数;
丢弃目标对象。
可以理解,拆分目标对象可以是将大的TB拆分成多个更小的TB,从而允许采用多个单信道传输,而不是必须采用宽带传输。
可选地,本申请实施例中,在第一操作包括触发终端进行资源选择的情况下,终端可以在m个时间单元之后进行资源选择;m为正整数。
可选地,本申请实施例中,在第一操作包括触发终端进行资源重选的情况下,终端可以在n个时间单元之后进行资源重选;n为正整数。
可选地,本申请实施例中,在第一操作包括重新获取第一配置参数的情况下,终端可以在p个时间单元之后重新获取第一配置参数;p为正整数。
可选地,本申请实施例中,在第一操作包括重新配置第一配置参数的情况下,终端可以在q个时间单元之后重新配置第一配置参数;q为正整数。
可选地,本申请实施例中,上述第一配置参数包括以下至少一项:
百分比参数;
参考信号接收功率(Reference Signal Receiving Power,RSRP)门限;
传输目标对象的资源单位的数量。
其中,上述百分比参数可以用于指示:终端的MAC层从终端的物理层上报的候选资源集中选择的候选资源,相对于终端的物理层上报的候选资源集中的候选资源的百分比参数。
可以理解,当终端的物理层上报的候选资源集中可以满足宽带传输的候选资源小于预设门限时,触发终端的物理层根据更新后的参数(即重新获取(和/或重新配置)的第一配置参数)重新进行资源选择,就可以获得更多的候选资源,从而增大终端的物理层上报的候选资源集中可以满足宽带传输的候选资源大于预设门限的几率。
可选地,本申请实施例中,上述丢弃目标对象可以理解为:丢弃目标对象的至少部分TB。可以理解,终端不再传输此TB或此TB的部分。
本申请实施例提供的数据传输方法,终端可以确定是否满足第一条件,并在确定满足 第一条件的情况下,采用宽带传输的方式传输目标对象;其中,目标对象包括以下至少一项:PSCCH、PSSCH、PSFCH、S-SSB、参考信号。由于终端可以直接根据是否满足第一条件,确定是否采用宽带传输的方式传输目标对象,因此,可以避免终端无法传输数据包有较大数据的情况,如此,可以提高终端的通信性能。
下面将针对终端的物理层如何确定候选资源集,以及终端的MAC层如何确定用于传输目标对象的资源,进行具体举例说明。
可选地,本申请实施例中,在上述步骤102之前,本申请实施例提供的数据传输方法还可以包括下述的步骤202、步骤203、步骤204以及步骤205中的至少一个。
步骤202、终端的MAC层触发终端的物理层确定候选资源集。
可选地,本申请实施例中,终端的MAC层可以向终端的物理层发送指示,以指示终端的物理层确定候选资源集;此时,终端的MAC层向终端的物理层发送的指示中包括对应的参数集(例如下述实施例中的第一参数),以帮助终端的物理层确定候选资源集。
可选地,本申请实施例中,上述步骤202具体可以通过下述的步骤202a实现。
步骤202a、终端的MAC层向终端的物理层发送第一参数。
其中,第一参数包括以下至少一项:传输所需资源的大小、候选资源的大小。
这里,上述传输所需资源的大小为以下任一项:
终端的MAC层确定采用宽带传输的方式进行传输的资源单位的数量;
候选资源集中的RB set内的资源单位的数量;
可被第一资源单位数量整除的数量。
第一资源单位为以下任一项:终端的MAC层确定采用宽带传输的方式进行传输的资源单位、RB set内的资源单位。
这里,候选资源的大小为以下任一项:
传输所需资源的大小
RB set内的资源单位的数量;
Q个资源单位。
本申请实施例中,Q为小于RB set内的资源单位的数量的正整数。
需要说明的是,传输所需资源的大小,候选资源的大小的单位是资源单位,即一般用子信道subchannel或交织块interlace的数量表示。
示例性地,由于终端的物理层可能是基于每个RB set进行资源选择的,因此,当终端确定采用宽带传输的方式进行传输时,此时终端的物理层确定的传输所需资源的大小就无法作为资源选择过程中候选资源的大小。因此,终端的MAC层可能会指示两个参数,一个是传输所需资源的大小,另一个则是候选资源的大小,此候选资源的大小可能等于或小于RB set的大小,以帮助物理层进行资源选择。但是,是否进行宽带传输也可能对于终端的物理层是透明的,此时,终端的MAC层也可能只指示一个虚拟的传输所需资源的大小,从而帮助物理层作为候选资源的颗粒度进行资源选择。还可能的是,终端的物理层可以基于整个资源池进行资源选择,此时,终端的MAC层就可以直接指示实际的传输所需资源的大小,作为物理层资源选择的候选资源颗粒度。
可选地,本申请实施例中,在终端的MAC层触发终端的物理层确定候选资源集之后,终端的物理层可以通过资源选择过程确定候选资源集(例如下述实施例中的第一候选资源 集),并向终端的MAC层上报该候选资源集,从而终端的MAC层可以从该候选资源集中,确定用于传输目标对象的目标资源。或者,终端可以执行下述的步骤203、步骤204以及步骤205中的至少一个,以使得终端的MAC层可以确定用于传输目标对象的目标资源。
步骤203、终端的物理层从第一候选资源集中排除满足第三条件的候选资源,得到第二候选资源集。
可选地,本申请实施例中,第一候选资源集中可以包括以下至少一项:时域资源、RB set标识、候选资源、频域资源等。
可选地,本申请实施例中,第二候选资源集中可以包括以下至少一项:时域资源、RB set标识、候选资源、频域资源等。
可选地,本申请实施例中,上述第三条件包括以下至少一项:
目标旁链路控制信息(Sidelink Control Information,SCI)指示的预留时间单元与第一候选资源所在的时间单元至少部分重叠;
目标SCI指示的频域资源与第一候选资源至少部分重叠;
第二RB set与第一候选资源所属的RB set至少部分相同。
本申请实施例中,上述目标SCI为:终端接收到的控制信息。
示例性地,目标SCI具体可以为终端在检测窗内的时隙t上接收到的控制信息,t为正整数。
本申请实施例中,上述第一候选资源为:第一候选资源集中的候选资源。
需要说明的是,在资源选择过程中,终端是将满足排除条件的资源从候选资源集排除,也就是上述第一候选资源集可以为第二候选资源集,即终端中并不会有两个候选资源集,此处是为了便于描述进行了资源排除后的第一候选资源集,而采用了“第二候选资源集”的描述。
可选地,本申请实施例中,上述第一候选资源具体可以为以下任一项:第一候选资源集中的任一个候选资源、第一候选资源集中的特定的候选资源。
本申请实施例中,上述第二RB set包括以下至少一项:目标SCI指示的RB set、目标SCI指示的频域资源所在的RB set。
可选地,本申请实施例中,在终端得到第二候选资源集后,终端的物理层可以直接向终端的MAC层上报第二候选资源集,从而终端的MAC层可以直接从第二候选资源集中,确定用于传输目标对象的目标资源。或者,终端可以执行下述的步骤204和步骤205中的至少一个,以使得终端的MAC层可以确定用于传输目标对象的目标资源。
步骤204、终端的物理层向终端的MAC层上报第二候选资源集。
可选地,本申请实施例中,上述步骤204具体可以通过下述的步骤204a实现。
步骤204a、在第二候选资源集满足第四条件的情况下,终端的物理层向终端的MAC层上报第二候选资源集。
本申请实施例中,上述第四条件包括以下至少一项:
第二候选资源集中的第二对象的数量大于第六门限;
第一比例大于第七门限。
其中,上述第六门限可以包括以下至少一项:协议预定义的门限、网络侧设备预配置的门限、网络侧设备配置的门限、终端确定的门限。
这里,第六门限可以是基于第三对象确定的;该第三对象包括以下至少一项:目标对象的数量、目标对象的大小。
其中,上述第二对象包括以下至少一项:
可采用宽带传输的方式进行传输的候选资源组合;
第二候选资源;
第二候选资源内的资源单位之和。
这里,第二候选资源包括以下至少一项:第一占比的时间单元内的候选资源、全部候选资源。
这里,第一比例为:第二对象,相对于第一候选资源集合中的第二对象的比例。
可以理解,第一比例为:第二候选资源集中的第二对象的数量,相对于第一候选资源集合中的第二对象的数量的比例。
可选地,本申请实施例中,在第四条件包括第二候选资源集中的第二对象的数量大于第六门限的情况下,若候选资源的颗粒度小于RB set时,如果第二候选资源集中没有同一个时间单元(例如时隙)上的候选资源可以组合以用于宽带传输,那么终端可以提高RSRP门限,再重复进行资源排除过程,包括重复执行步骤203。由于此时RSRP门限值提高了,那么满足资源排除条件的候选资源自然就会减少,使得第二候选资源集中的候选资源变多,从而增大第二候选资源集中有足够数量的时间单元上有可以用于宽带传输的候选资源组合。
可选地,本申请实施例中,在终端的物理层向终端的MAC层上报第二候选资源集之后,终端的MAC层可以直接从第二候选资源集中,确定用于传输目标对象的目标资源。或者,终端可以执行下述的步骤205,以使得终端的MAC层可以从第二候选资源集中,确定用于传输目标对象的目标资源。
步骤205、终端的MAC层从第二候选资源集中,确定用于传输目标对象的目标资源。
下面将以两种不同的场景,举例说明终端是如何确定目标资源的。
场景一、终端的物理层在每个RB set进行独立资源选择的场景
可以理解,当终端的物理层在每个RB set进行独立资源选择,则终端上报给MAC层时,是每个RB set上都会上报一个候选资源集,所以此时,第二候选资源集相当于所有RB set上报的候选资源集的全集。而终端的MAC若要采用宽带传输的方式进行传输,就需要从这些独立的候选资源集中选择候选资源组合作为目标资源,用于进行宽带传输。
可选地,本申请实施例中,上述步骤205具体可以通过下述的步骤205a、步骤205b、步骤205c、步骤205d以及步骤205e中的至少一个实现。
步骤205a、终端从第二候选资源集中的全部RB set中,随机选择候选资源,直至T个时间单元内的候选资源的数量大于或等于第八门限。
本申请实施例中,T为正整数。
可以理解,终端可以通过步骤205a,选择出一定数量的时间单元,且这些时间单元上都有足够的候选资源可以执行宽带传输,从而终端可以从这些时间单元里通过随机选择候选资源组合的方式确定目标资源。
可选地,本申请实施例中,上述第八门限可以包括以下至少一项:协议预定义的门限、网络侧设备预配置的门限、网络侧设备配置的门限、终端确定的门限。
步骤205b、终端从第二候选资源集中,随机选择候选资源,直至选择的候选资源中的 第四对象满足第五条件。
可以理解,终端可以通过步骤205b,选择出目标资源中的至少部分资源。
本申请实施例中,上述第四对象包括以下任一项:候选资源、候选资源组合。
本申请实施例中,上述第五条件包括以下任一项:该第四对象的数目大于或等于第九门限、第二比例大于或等于第十门限。
其中,第二比例为:第四对象,相对于第二候选资源集中的第四对象的比例。
可以理解,第二比例为:终端选择的候选资源中的第四对象的数量,相对于第二候选资源集中的第四对象的数量的比例。
步骤205c、在第二候选资源集中包括可采用宽带传输的方式进行传输的候选资源组合的情况下,终端从候选资源组合中,随机选择候选资源组合。

场景二、候选资源的颗粒度为宽带传输的颗粒度的场景
可选地,本申请实施例中,上述步骤205具体可以通过下述的步骤205f、步骤205g、以及步骤205h中的至少一个实现。

可选地,本申请实施例中,上述第六条件包括以下至少一项:
包含有候选资源的时域资源;
时域位置最前的时域资源;
包含的候选资源的数量大于第十七门限的时域资源。
示例性地,假设第六条件包括时域位置最前的时域资源,则终端可以先从第二候选资源集中选择时域位置最前的Y个时域资源,再从该Y个时域资源中选择候选资源。或者,终端可以先从第二候选资源集中选择时域位置最前的Z%(即第二候选资源集中的全部时域资源的Z%)的时域资源,再从该Z%的时域资源中选择候选资源。
下面将以两个具体的示例,进行具体举例说明。
示例一、触发宽带传输的条件
终端的MAC层在数据包到达之后,会根据服务质量(Quality of Service,QoS)优先级等信息确定如何传输数据包。同样地,是否触发宽带传输也需要终端的MAC层根据各种条件或信息进行判断。例如,延用NR的机制,当终端的MAC层确定了传输所需的资源(例如子信道)数量大于一个信道(即RB set)的子信道数量时,就等于终端的MAC层触发了 宽带传输。此时,相当于由终端的MAC层确定根据什么条件触发宽带传输,因此,可以规范化一些触发宽带传输的条件使得宽带传输的触发更加合理。例如,终端的MAC层需要考虑当前缓存的TB的数据量,如果已缓存的数据量较大,那么更倾向于用宽带传输一个大包,而不是拆分成多个TB进行发送。或当前到的包就是一个大包,也倾向于用宽带传输。
与此同时,还可以根据信道状况进行判断,例如CBR的测量值较低,可以认为当前信道状况良好,利于进行宽带传输,还可以在CBR的测量值较大时,认为拆分多个TB传输的可靠性更低,更倾向于进行宽带传输。除此之外,可以采取先进行资源选择,后判断是否进行宽带传输的方式,比如当终端的MAC层从物理层上报的候选资源集中选择了跨信贷(即RB set)的资源,就自然得触发宽带传输。
示例二、资源选择流程
在NR R16/R17中,终端的MAC层会指示物理层所需子信道的大小,此时终端的物理层就会将这个子信道的大小作为候选资源的颗粒度,进行资源排除和资源选择。当终端的MAC层触发宽带传输时,指示的候选资源大小有两种可能。
一种是像R16/R17一样,直接指示宽带传输所需在子信道的大小N,此时终端的物理层将N个子信道作为候选资源的颗粒度,进行资源排除和资源选择。在进行资源排除时,一种方法是按照R16/R17,当检测到的资源的预留资源指示了候选资源所在的时隙时,就排除这些候选资源,另一种方法时,当检测到的资源的预留资源与候选资源重叠或部分重叠时,排除这些候选资源。最终,终端的物理层将得到的候选资源集合(即第二候选资源集)上报给终端的MAC层。
另一种是考虑到终端的物理层的资源选择过程可能是在每个信道(即RB set)上独立进行的,此时终端的MAC层指示的子信道的大小就应该是信道(即RB set)包含的子信道的数目M,或者可以被M整除的数目m。终端的物理层将M或m个子信道作为候选资源的颗粒度,然后在每个信道(即RB set)面独立进行资源排除和资源选择。此时,按照上面所述,同样有两种资源排除方法,一种是排除预留资源所在时隙上面所有的候选资源,另一种是只排除与预留资源重叠或部分重叠的候选资源。最终,终端的物理层将得到的候选资源集合(即第二候选资源集)上报给终端的MAC层。此时,由于每个信道(即RB set)上面的资源选择是独立进行的,候选资源集(即第二候选资源集)中的候选资源需要携带RB set标识,或每个信道(即RB set)独立上报候选资源集,使得终端的MAC层可以区分不同RB set的候选资源。
在本申请实施例中,终端可以确定是否满足第一条件,并在确定满足第一条件的情况下,采用宽带传输的方式传输目标对象;其中,目标对象包括以下至少一项:PSCCH、PSSCH、PSFCH、S-SSB、参考信号。由于终端可以直接根据是否满足第一条件,确定是否采用宽带传输的方式传输目标对象,因此,可以避免终端无法传输数据包有较大数据的情况,如此,可以提高终端的通信性能。
在相关技术中,在NR Sidelink终端变的越来越多,LTE Sidelink终端数量变的越来越少的情况下,给LTE Sidelink终端划分的频段利用率较低,因此一些方法被提出使得NR Sidelink终端可以在这些频段上与LTE Sidelink终端共存。例如,利用双模终端既有LTE模块又有NR模块的特点,通过LTE模块检测LTE终端的资源预留实现与LTE终端的共存。因此,需要定义LTE模块发送的信息内容,以及NR模块如何根据LTE模块发送的信息进 行资源选择,以实现共存的目的。
为了解决上述技术问题,本申请实施例提供了一种数据传输方法。图4示出了本申请实施例提供的一种数据传输方法的流程图。如图4所示,本申请实施例提供的数据传输方法可以包括下述的步骤301和步骤302。
步骤301、终端的第一模块根据第二模块发送的第一信息,执行资源选择操作。
可选地,本申请实施例中,在终端确定要传输数据的情况下,终端的第一模块可以根据第二模块发送的第一信息,执行资源选择操作。
可选地,本申请实施例中,上述第一模块具体可以为:新空口(New Radio,NR)模块。上述第二模块具体可以为:长期演进(Long Term Evolution,LTE)模块。
需要说明的是,上述NR模块可以理解为:具备NR RAT的相关检测、解码、编码能力的软件或硬件模块。上述LTE模块可以理解为:具备LTE RAT的相关检测、解码、编码能力的软件或硬件模块。
本申请实施例中,上述第一信息用于触发终端执行资源选择操作。
可选地,本申请实施例中,上述第一信息包括以下至少一项:
SCI的时域位置;
时域预留信息;
频域预留信息;
预留资源的时域位置;
预留资源的频域位置;
预留周期;
优先级;
RSRP测量值;
信号强度指示RSSI测量值;
第一资源集合;
资源冲突指示;
第一时域信息。
其中,上述资源冲突指示用于指示:终端的第一模块的MAC层选择的传输资源,与LTE无线接入类型无线接入类型(Radio Access Technology,RAT)的预留资源至少部分重叠;上述第一资源集合为:第一选择窗中排除LTE RAT的预留资源后的资源集合。
需要说明的是,第一资源集合还可以为第一选择窗中排除LTE RAT的预留资源和第二资源集合后的资源集合。该第二资源集合为终端的俩个模块因半双工,和或无法与另一模块同时发送,接收等原因造成的第二模块和或第一模块无法检测的资源,和或在这些资源上按照资源池允许的预留周期推断出来的可能的预留资源组成的资源集合。半双工原因包括因第一模块发送数据,SSB等造成第二模块无法接收LTE SCI的情况,还包括因第二模块发送数据,SSB等造成第一模块无法接收NR SCI的情况。
需要说明的是,预留周期可能为LTE RAT携带的SCI指示的预留周期值,也可能是经过LTE逻辑时隙与物理时隙的规则换算过之后的逻辑时隙数(也可以成为逻辑预留周期),从而方便NR模块计算预留资源位置。如果是前者,第一信息中还可能包括LTE的逻辑时隙与物理时隙的换算规则。
可以理解,此资源冲突指示即可能只指示MAC层选择的传输资源中,存在冲突的资源,而不指示具体哪个资源,此时可以仅使用1bit信息就可完成指示,还可能是指示MAC层选择的传输资源中的哪一个传输资源,是被判断为冲突的资源,此时可能由bitmap指示,也可能根据特定的映射规则进行指示,例如重用终端合作信息中的资源冲突指示的映射规则。
可选地,本申请实施例中,上述第一选择窗为以下任一项:
终端的第二模块确定的选择窗;
终端的第一模块向终端的第二模块指示的选择窗。
可以理解,如果终端的第二模块要向第一模块指示资源相关信息,就需要在一定的时间范围内确定哪些资源需要排除,或哪些资源推荐使用。因此,就需要一个时间窗。这个时间窗可能是第一模块指示给第二模块的,也可能是第二模块自己实现的。
可选地,本申请实施例中,上述排除LTE RAT的预留资源包括以下至少一项:
排除LTE RAT的所有预留资源;
排除LTE RAT的所有预留资源中,RSRP测量值大于第二十一门限值的预留资源;
排除LTE RAT的所有预留资源中,RSSI测量值大于第二十二门限值的预留资源;
排除LTE RAT的所有预留资源中,优先级大于第二预设优先级的预留资源。
步骤302、终端在资源选择操作选择的目标资源上,传输目标对象。
本申请实施例中,目标资源为用于传输目标对象的资源。
可选地,本申请实施例中,终端可以在目标资源上,采用宽带传输的方式传输目标对象。
需要说明的是,针对终端采用宽带传输的方式传输目标对象的说明,可以参考上述实施例中的具体描述,本申请实施例在此不再赘述。
本申请实施例提供的数据传输方法,终端的第一模块可以根据第二模块发送的第一信息,执行资源选择操作,并在资源选择操作选择的目标资源上,传输目标对象。由于终端的第一模块可以根据第二模块发送的第一信息,选择用于传输目标对象的目标资源,并在该目标资源上传输目标对象,因此,可以避免终端的NR模块选择的资源与其他LTE RAT的预留资源产生碰撞,如此,可以提高终端的通信性能。
下面将以第一信息包括不同的信息为例,举例说明终端是如何执行资源选择操作的。
可选地,在本申请实施例的一种可能的实现方式中,上述第一信息包括第一时域信息。具体地,上述步骤301具体可以通过下述的步骤301a和步骤301b中的至少一项实现。
步骤301a、终端的第一模块根据第一时域信息,从候选资源集中排除第一时域上的候选资源。
本申请实施例中,上述第一时域为第一时域信息指示的时域。
需要说明的是,第一时域为两个模块可能产生半双工冲突和或同时收发冲突的时域集合,例如终端的第二模块发送数据,SSB,和或接收数据,SSB等的时间单位。此时,第一模块无法在第一时域上检测NR RAT的SCI,和或第二模块无法在第一时域上检测LTE RAT的SCI。因此NR模块需要排除这些时域上的候选资源,从而避免与预留在这些时域上的发送资源产生冲突。
可选地,本申请实施例中,在终端的第一模块从候选资源集中排除第一时域上的候选资源之后,终端的第一模块可以在排除后的候选资源集中选择至少部分目标资源。
步骤301b、终端的第一模块根据第一时域信息,从候选资源集中排除第二时域上的候选资源。
本申请实施例中,上述第二时域为目标SCI指示预留的至少部分时域;该目标SCI为假设在第一时域上接收到的SCI。
可以理解,由于半双工等原因,终端的NR模块无法在第一时域上检测NR RAT的SCI,因此就无法根据在第一时域上检测到的SCI进行资源排除,和或终端的LTE模块无法在第一时域上检测LTE RAT的SCI,因此就无法根据在第一时域上检测到的SCI进行资源排除。所以,终端需要假设在第一时域上收到了SCI,且这些SCI按照资源池配置的预留周期进行了资源预留,就可以推断出终端为了避免资源冲突,同样需要避开第二时域上的候选资源。
可选地,本申请实施例中,在终端的第一模块从候选资源集中排除第二时域上的候选资源之后,终端的第一模块可以在排除后的候选资源集中选择至少部分目标资源。
需要说明的是,针对终端的第一模块选择至少部分目标资源的方式的说明,可以参考上述实施例中的具体描述,本申请实施例在此不再赘述。
可选地,在本申请实施例的另一种可能的实现方式中,上述第一信息包括预留资源的时域位置、RSRP测量值以及优先级中的至少一个。具体地,上述步骤301具体可以通过下述的步骤301c实现。
步骤301c、终端的第一模块根据第一信息,从候选资源集合中排除满足第八条件的候选资源,以得到目标资源。
本申请实施例中,上述第八条件包括以下至少一项:
RSRP测量值大于第二十门限;
优先级大于第一预设优先级;
预留资源的时域位置与候选资源所在的时域至少部分重叠。
可选地,本申请实施例中,在终端的第一模块从候选资源集合中排除满足第八条件的候选资源之后,终端的第一模块可以在排除后的候选资源集中选择目标资源。
可以理解,此时终端的第二模块传递的第一信息为预留资源的时域位置,RSRP测量值优先级等。相较于第二模块将所有的检测结果传递给第一模块的方式,只传递预留资源的时域位置及相关RSRP测量值优先级的方法传递的信息更少,且不需要NR模块再根据SCI的位置和预留周期去推出具体的预留资源位置,从而进行资源排除,而是直接排除这些时域位置上的候选资源。并且,由于LTE RAT下的逻辑时隙和NR RAT下的逻辑时隙的位置不完全相同,由LTE模块来计算更方便,不然NR模块还需要了解,甚至需要LTE模块传递LTE RAT的物理时隙与逻辑时隙的换算规则。
需要说明的是,此时,第一信息中还可能包括预留周期,或预留周期对应的逻辑时隙数。
需要说明的是,针对终端的第一模块在排除后的候选资源集中选择目标资源的方式的说明,可以参考上述实施例中的具体描述,本申请实施例在此不再赘述。
可选地,在本申请实施例的又一种可能的实现方式中,上述第一信息包括资源冲突指示。具体地,上述步骤301具体可以通过下述的步骤301d实现。
步骤301d、终端的第一模块的MAC层根据第一信息,从候选资源集中选择目标资源。
可选地,本申请实施例中,终端的第一模块可以从候选资源集中,排除与LTE RAT的 预留资源至少部分重叠的候选资源,并从排除后的候选资源集中选择目标资源。
需要说明的是,针对终端的第一模块从排除后的候选资源集中选择目标资源的方式的说明,可以参考上述实施例中的具体描述,本申请实施例在此不再赘述。
可选地,在本申请实施例的再一种可能的实现方式中,上述第一信息包括第一资源集合。具体地,上述步骤301具体可以通过下述的步骤301e实现。
步骤301e、终端的第一模块的MAC层根据第一信息,从第一资源集合与候选资源集的交集中选择目标资源。
可选地,本申请实施例中,第一信息包括第一资源集合。而第一资源集合为LTE模块从资源选择窗中排除满足一定条件的LTE预留资源而得到的,即NR RAT选择后与LTE RAT预留资源碰撞概率较低的资源集。此时,MAC层从第一资源集合与候选资源集的交集中选择目标资源的话,不仅可以降低与LTE RAT的预留资源碰撞的概率,还会降低与NR RAT的预留资源碰撞的概率。
需要说明的是,针对终端的第一模块从第一资源集合与候选资源集的交集中选择目标资源的方式的说明,可以参考上述实施例中的具体描述,本申请实施例在此不再赘述。
