Description

上行传输的发送方法、装置、设备及存储介质 技术领域
本公开涉及通信领域,特别涉及一种上行传输的发送方法、装置、设备及存储介质。
背景技术
新空口非授权(New Radio unlicensed,NR-U)的标准化正在制定,该部分标准化的目的是能够让NR系统在非授权频段(unlicensed band)上工作。
因为存在多种无线传输技术使用非授权频段进行传输,比如无线保真网络(WIreless-FIdelity,WIFI),所以需要保证多种无线传输技术间公平使用这部分频段。NR系统采用先听后说(Listen-Before-Talk,LBT)机制来保证公平性,也即UE在发送上行数据前,需要先进行一段时间监听,保证信道空闲的情况下才能进行发送。

具体实施方式
这里将详细地对示例性实施例进行说明,其示例表示在附图中。下面的描述涉及附图时,除非另有表示,不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本公开相一致的所有实施方式。相反,它们仅是与如所附权利要求书中所详述的、本公开的一些方面相一致的装置和方法的例子。
NR-U是让NR系统在非授权频段上工作,NR-U的工作场景包括如下场景中的至少一种:
NR授权和NR非授权的载波聚合,NR授权小区为主小区;
授权频段长期演进(Long Term Evolution,LTE)和NR-U间的双连接,即主小区和主辅小区间的双连接;NR-U独立工作;
NR-U独立工作的小区在上行传输时采用授权频段;
NR授权频段和NR-U间的双连接,即主小区和主辅小区间的双连接。
在非授权频段上,由于越来越多的通信系统同时使用该非授权频段,故非授权频段上的通信一般采用LBT机制以保证多种通信系统公平的使用该非授权频段。LBT机制指设备在发送上行数据之前需要先对非授权频段上的频段进 行监听,当监听到频段空闲时,占用该频段发送上行数据。
示意性的,LBT机制是竞争窗口大小(Contention Window Size,CWS)可变的随机退避型LBT机制。发送设备可以根据前一次传输的结果调整CWS。比如前一次传输过程中的一个参考时间内传输的数据中,没有被正确接收的比例为X,当X大于一个门限时,则CWS值增加。为了细化LBT过程中的参数设置,在LBT机制中设置了四种优先级,每种优先级对应不同的参数配置,不同业务类型的数据传输对应不同的优先级。
以LBT Cat.4为例,设备首先在第一时间粒度检测信道是否空闲,若检测到该信道空闲,在第一竞争窗口内选取随机数的值N,并以第二时间粒度为时间粒度进行信道检测;如果在第二时间粒度检测到该信道空闲,且随机数的值不为0,则将随机数的值减1,并继续以第二时间粒度为时间粒度进行信道检测;如果在第二时间粒度检测到该信道忙,则再次以第一时间粒度为时间粒度进行信道检测;如果再次在第一时间粒度检测到该信道空闲,且随机数的值不为0,则将随机数的值减1,并恢复以第二时间粒度为时间粒度进行信道检测;直至随机数的值减为0,才表示信道空闲。
举例来说,第一时间粒度为16us+M*9us,第二时间粒度为9us,则先检测16us+M*9us内信道是否空闲,若信道空闲,则在竞争窗口内选取随机数的值N,再以9us为粒度进行检测,若信道空闲,则N-1,并继续以9us为粒度检测;否则,以16us+M*9us为粒度进行信道检测,当检测信道空闲,则N-1,并恢复以9us为粒度检测直到随机数为0才表示信道空闲,可以使用。
其中,上述M的取值由表-1和表-2里的m p决定,信道接入优先级值p不同,M取值不同。表-1为下行LBT Cat.4四种优先级参数配置,表-2为上行LBT Cat.4四种优先级参数配置,两者只是配置的数值略有不同。
表-1
Figure PCTCN2019072424-appb-000001
表-2
Figure PCTCN2019072424-appb-000002
上述表-1和表-2所示的四种信道接入优先级中,p值越小,对应的优先级越高。m p是一个延迟时间中所包含ECCA(Extended Clear Channel,延长空闲信道评估)的个数,每个延迟时间是由固定的16us时长和m p个ECCA组成的,即上文介绍的第一时间粒度。CW min,p和CW max,p是最小竞争窗口值和最大竞争窗口值,在LBT过程中的CWS便是在这两个值之间生成的,然后再由0到生成的竞争窗口CW p中随机生成的退避计数器N来决定LBT信道检测过程中退避的时间长短,而T mcot,p是每种优先级对应的LBT机制执行成功之后能占用信道的最大时长,由上表可知相较于优先级1,2而言,优先级3,4的LBT过程的执行时间较长,获得信道接入的机会相对较低,为了保证公平性,使用这两种优先级的数据传输能占用的最大传输时间也相对较长。
需要说明的是,上述LBT机制只是示例性介绍说明,随着通信技术的演进,上述LBT机制可能有所变化,或者有新的信道接入机制产生,但都是适用于本公开描述的技术方案。
参见图1,示出了NR协议栈的结构示意图,图1中的NR系统中的终端侧的协议栈从下到上依次是物理层(Physical,PHY)01、媒体访问控制层(Medium Access Control,MAC)02、无线链路控制子层(Radio Link Control,RLC)03、分组数据会聚协议子层(Packet Data Convergence Protocol,PDCP)04、无线资源控制层(Radio Resource Control,RRC)05、非接入层(Non-access stratum,NAS)06。基站侧的协议除了NAS层06位于访问和移动管理功能(Access and Mobility Management Function,AMF)上,其它层与终端侧的相同。
NR系统在进行调度请求(Scheduling Request,SR)传输时,终端确定终端内部是否存在与SR传输重叠的物理上行共享信道(Physical Uplink Shared Channel,PUSCH)传输,在确定不存在与SR传输重叠的PUSCH传输后,对 非授权频段进行LBT。终端通过LBT检测出非授权频段的信道状态为空闲,也即当LBT成功时,终端进行SR传输。
然而,由于LBT会持续一段时间,在确定LBT成功时,终端之前判断的SR传输是否与PUSCH传输存在重叠可能已经失效(也即最初的判断结果为不重叠,但LBT成功时又存在了重叠),在LBT成功时进行SR传输,会与PUSCH传输存在重叠,导致传输失败。
图2示出了本公开一个示例性实施例提供的上行传输的发送方法的实施环境的示意图,图2中包括:终端210和基站220。
终端210的数量通常为多个,每个基站220所管理的小区内可以分布一个或多个终端210。终端120可以包括各种具有无线通信功能的手持设备、车载设备、可穿戴设备、计算设备或连接到无线调制解调器的其它处理设备,以及各种形式的用户设备(User Equipment,UE),移动台(Mobile Station,MS),终端设备(terminal device)等等。终端210用于在非授权频段上,向基站220发送第一上行传输。终端210在向基站220发送第一上行传输时,通过LBT对非授权频段上的空闲信道进行检测,当LBT成功时,终端210立即向基站220发送第一上行传输。
基站220是一种部署在接入网中用以为终端210提供无线通信功能的设备。基站110可以包括各种形式的宏基站,微基站,中继站,接入点等等。在采用不同的无线接入技术的系统中,具备基站功能的设备的名称可能会有所不同,例如在5G NR系统中,称为gNodeB或者gNB。随着通信技术的演进,“基站”这一名称可能会变化。基站220用于接收非授权频段上。
本公开实施例描述的技术方案可以适用于NR系统,也可以适用于NR系统后续的演进系统。
图3示出了本公开一个示例性实施例提供的上行传输的发送方法的流程图,该方法可以应用于图2所示的实施环境,该方法包括:
步骤301,终端在非授权频段上发送第一上行传输前,对非授权频段进行LBT。
非授权频段是不需要管理机构的许可,可只要符合管理机构的法规(Regulation)就可以直接使用的频谱资源。
可选的,终端在非授权频段上发送第一上行传输前,不确定是否存在与第一上行传输重叠的第二上行传输,直接对非授权频段进行LBT。
当LBT不成功时,转至步骤302;当LBT成功时,转至步骤303。
步骤302,当LBT不成功时,终端延长LBT或重新开始LBT或取消本轮传输。
当LBT不成功时,终端确定非授权频段上存在其它终端正在进行上行传输。终端通过延长本轮LBT或重新开始LBT,直至确定可以发送第一上行传输;或,终端取消本轮传输,即放弃本轮发送第一上行传输。
步骤303,当LBT成功时,终端确定是否存在与第一上行传输重叠的第二上行传输。
当LBT成功时,终端授权频段上不存在其它终端正在进行上行传输。终端需要判断在终端内部是否存在与第一上行传输重叠的第二上行传输。第一上行传输和第二上行传输是同一个终端发送的上行传输。其中,第一上行传输是准备传输的上行数据,第二上行传输时正在传输的一条或多条上行数据。
可选的,第一上行传输或第二上行传输的上行传输类型包括:物理随机接入信道(Physical Random Access Channel,PRACH)传输、SR传输、应答/非应答(Acknowledgement/Negative Acknowledgement,ACK/NACK)传输、信道质量指示(Channel Quality Indication,CQI)传输、信道探测参考信号(Sounding Reference Signal,SRS)传输、PUSCH传输等。
可选的,第一上行传输和第二上行传输可能是位于同一载波或不同载波或不同控制的服务小区组(Controlled Group,CG)上的上行传输,而CG包括主演进型基站(Master Evolved Node B,MeNB)控制的服务小区组(MeNB Controlled Group,MCG)和次演进型基站(Secondary Evolved Node B,SeNB)控制的服务小区组(SeNB Controlled Group,SCG)。
当终端确定不存在与第一上行传输重叠的第二上行传输时,转至步骤304;当终端确定存在与第一上行传输重叠的第二上行传输时,转至步骤305。
步骤304,当在非授权频段上LBT成功,且不存在与第一上行传输重叠的第二上行传输时,终端在非授权频段上发送第一上行传输。
步骤305,当在非授权频段上LBT成功,且存在与第一上行传输重叠的第二上行传输时,终端优先传输第一上行传输和第二上行传输中的至少一个上行传输。
在一种可选的实施方式中,当在非授权频段上LBT成功,且存在与第一上行传输重叠的第二上行传输,且第一上行传输和第二上行传输满足同时传输条件时,终端在非授权频段上同时发送第一上行传输和第二上行传输。同时传输条件包括:第一上行传输和第二上行传输符合预定义的传输类型;和/或,终端的发送功率满足第一上行传输和第二上行传输同时传输时所需的功率。
可选的,当第一上行传输和第二上行传输的传输类型符合预定义的传输类型时,第一上行传输和第二上行传输重叠,但是终端可以同时传输第一上行传输和第二上行传输。
比如,预定义的传输类型包括SR传输和上行共享信道(UpLink-Shared Channel,UL-SCH)传输,或,ACK/NACK传输和UL-SCH传输。
示意性的,当第一上行传输是SR传输,第二上行传输是上行共享信道(UpLink-Shared Channel,UL-SCH)传输时,SR传输和UL-SCH传输符合预定义的传输类型,故当在非授权频段上LBT成功,且SR传输与UL-SCH传输存在重叠时,终端可以同时传输SR传输和UL-SCH传输。
或者,当第一上行传输是ACK/NACK传输,第二上行传输是UL-SCH传输时,ACK/NACK传输和UL-SCH传输符合预定义的传输类型,故当在非授权频段上LBT成功,且ACK/NACK传输与UL-SCH传输存在重叠时,终端可以同时传输ACK/NACK传输和UL-SCH传输。
可选的,当在非授权频段上LBT成功,且存在与第一上行传输重叠的第二上行传输,且第一上行传输和第二上行传输不满足同时传输条件,且第一上行传输的优先级高于第二上行传输的优先级时,终端优先发送第一上行传输,在第一上行传输发送完毕后再发送第二上行传输;
或,当在非授权频段上LBT成功,且存在与第一上行传输重叠的第二上行传输,且第一上行传输和第二上行传输不满足同时传输条件,且第一上行传输的优先级低于第二上行传输的优先级时,终端优先发送第二上行传输,在第二上行传输发送完毕后再发送第一上行传输;
或,当在非授权频段上LBT成功,且存在与第一上行传输重叠的第二上行传输,且第一上行传输和第二上行传输不满足同时传输条件时,终端延长LBT直至第二上行传输发送完毕,若在发送第二上行传输的过程中LBT成功,则在第二上行传输发送完毕后发送第一上行传输;
或,当在非授权频段上LBT成功,且存在与第一上行传输重叠的第二上 行传输,且第一上行传输和第二上行传输不满足同时传输条件时,终端取消传输第一上行传输和/或第二上行传输。
在另一种可选的实施方式中,当在非授权频段上LBT成功,且存在与第一上行传输重叠的第二上行传输,且第一上行传输的优先级高于第二上行传输的优先级时,终端在非授权频段上发送第一上行传输。
可选的,第一上行传输和第二上行传输的优先级是根据两个上行传输对应的业务决定的,和/或,第一上行传输和第二上行传输的优先级是由通信系统定义的。
可选的,当发送第二上行传输和发送第一上行传输的时间间隔小于预设间隔时间时,终端在发送第一上行传输结束后,不再进行LBT,直接发送第二上行传输。
可选的,当发送第二上行传输和发送第一上行传输的时间间隔大于预设间隔时间时,终端在非授权频段上完成发送第一上行传输后,再次在非授权频段上进行LBT。终端在LBT成功时,发送第二上行传输。

在基于图3所示的实施例中,通过对无线通信系统的协议栈来说明上行传输的发送方法,图5示出了本公开另一个示例性实施例提供的上行传输的发送方法的流程图,该方法可以应用于图2所示的实施环境,该方法说明了由终端的物理层来判断第一上行传输和第二上行传输是否重叠,该方法包括:
步骤501,终端在非授权频段上发送第一上行传输前,终端的物理层对非授权频段进行LBT。
步骤501与步骤401的内容相同,这里不再赘叙。

步骤505,当终端的物理层确定存在与第一上行传输重叠的第二上行传输时,终端的物理层向终端的MAC层发送第二指示。
当终端的物理层确定存在与第一上行传输重叠的第二上行传输,终端的物 理层确定需要判定第一上行传输和第二上行传输的优先级,根据优先级决定传输次序。终端的物理层向终端的MAC层发送第二指示。第二指示,用于终端的物理层向终端的MAC层发送存在与第一上行传输重叠的第二上行传输的信息。

步骤603,当LBT成功时,终端确定是否存在与第一上行传输重叠的测量间隔。
当LBT成功时,终端确定授权频段上不存在其它终端正在进行上行传输。 终端需要判断在终端内部是否存在与第一上行传输重叠的测量间隔。测量间隔用于测量信道的质量,比如测量频率、信道容量等。其中,第一上行传输是准备传输的上行数据。
当终端确定不存在与第一上行传输重叠的测量间隔时,转至步骤604;当终端确定存在与第一上行传输重叠的测量间隔时,转至步骤605。
步骤604,当在非授权频段上LBT成功,且不存在与第一上行传输重叠的测量间隔时,终端在非授权频段上发送第一上行传输。
步骤605,当在非授权频段上LBT成功,且存在与第一上行传输重叠的测量间隔、且第一上行传输的类型为预定类型时,终端在非授权频段上发送第一上行传输。
可选的,预定类型包括第一上行传输对应的业务的优先级高于测量间隔的优先级,或,预定类型包括通信系统定于第一上行传输的优先级高于测量间隔的优先级。故当在非授权频段上LBT成功,且存在与第一上行传输重叠的测量间隔、且第一上行传输的类型为预定类型时,终端在非授权频段上发送第一上行传输。
比如,当第一上行传输属于低时延高可靠连接(Ultra-Reliable and Low Latency Communications,URLLC)时,当在非授权频段上LBT成功,且存在与第一上行传输重叠的测量间隔时,终端在非授权频段上发送第一上行传输。
可选的,当在非授权频段上LBT成功,且存在与第一上行传输重叠的测量间隔、且第一上行传输的类型不为预定类型时,终端取消发送第一上行传输;或,当在非授权频段上LBT成功,且存在与第一上行传输重叠的测量间隔、且第一上行传输的类型不为预定类型时,终端延长LBT直至测量间隔结束,若在测量间隔的过程中LBT成功,则在测量间隔结束后发送第一上行传输。
可选的,终端延长LBT直至测量间隔结束,若在测量间隔的过程中LBT失败,则重新进行另一LBT,另一LBT的信道评估时长等于目标时长。其中,目标时长是测量间隔的剩余时长和LBT下一轮信道评估时长中的较大值,目标时长=max(测量间隔的剩余时长,LBT下一轮信道评估时长)。LBT下一轮信道评估时长是根据上一轮传输结果调整CWS而确定的。
可选的,终端根据重新进行的另一LBT的结果,执行相对应的操作,操作内容如上述步骤602至步骤605的内容相同,这里不再赘叙。
综上所述,本公开实施例提供的方法,在LBT成功后,再判断是否存在 与第一上行传输重叠的测量间隔,且第一上行传输的类型为预定类型时,终端在非授权频段上发送第一上行传输,从而保证在LBT持续的时间后的重叠判断的准确性,避免终端在发送第一上行传输时,因重叠判断结果的不准确,而导致与第二上行传输发生碰撞。
在基于图3所示的实施例中,图7示出了本公开另一个示例性实施例提供的上行传输的发送方法的流程图,该方法可以应用于图2所示的实施环境,该方法说明了终端在进行LBT前对第一上行传输进行一次重叠的判断,该方法包括:
步骤701,终端在非授权频段上发送第一上行传输前,确定是否存在与第一上行传输重叠的第二上行传输或测量间隔。
步骤702,当确定不存在与第一上行传输重叠的第二上行传输或测量间隔,终端对非授权频段进行LBT。
终端在非授权频段上发送第一上行传输前,进行一次重叠的判断。此处能够兼容相关技术中的设计。
当确定不存在与第一上行传输重叠的第二上行传输或测量间隔时,终端对非授权频段进行LBT。
LBT是指终端在发送第一上行传输前,先对待发送的非授权频段进行监听,当监听到非授权频段空闲时,告知终端非授权频段空闲,终端即可发送第一上行传输。
步骤703至步骤706与步骤302至步骤305内容相同,这里不再赘叙。
综上所述,本公开实施例提供的方法,终端通过在LBT前进行一次重叠的判断,在LBT后再次进行一次重叠判断。一方面,在LBT前进行一次重叠的判断能够兼容已有的设计;另一方面,在LBT后再次进行一次重叠判断,能够保证重叠判断的准确性,从而保证LBT成功时,终端在传输第一上行传输时不会由于终端内部的重叠问题导致传输失败。
在基于图3所示的实施例中,图8示出了本公开另一个示例性实施例提供的上行传输的发送方法的流程图,该方法可以应用于图2所示的实施环境,该方法说明了终端在进行LBT前对第一上行传输进行一次重叠的判断,该方法包括:

可选的,同时传输条件包括:第一上行传输和第二上行传输符合预定义的传输类型;和/或,终端的发送功率满足第一上行传输和第二上行传输同时传输时所需的功率。
步骤802,当确定存在与第一上行传输重叠的第二上行传输,且第一上行传输和第二上行传输符合同时传输条件时,对非授权频段进行LBT。
终端在非授权频段上发送第一上行传输前,进行一次重叠的判断。当确定存在与第一上行传输重叠的第二上行传输,且第一上行传输和第二上行传输符合同时传输条件时,终端对非授权频段进行LBT。
LBT是指终端在发送第一上行传输前,先对待发送的非授权频段进行监听,当监听到非授权频段空闲时,告知终端非授权频段空闲,终端即可发送第一上行传输。
步骤803至步骤806与步骤302至步骤305内容相同,这里不再赘叙。
综上所述,本公开实施例提供的方法,终端通过在LBT前进行一次重叠的判断,在LBT后再次进行一次重叠判断,保证LBT成功时,终端在传输第一上行传输时不会由于终端内部的重叠问题导致传输失败。
