Description

终端唤醒控制方法、装置及存储介质 技术领域
本公开涉及无线通信技术领域,特别涉及一种终端唤醒控制方法、装置及存储介质。
背景技术
为了应对移动数据日益增长的通信需求,业内提出将蜂窝移动通信技术扩展到非授权频段上,使得蜂窝移动通信技术能够满足非授权频段的法规要求。
为了节约终端电量,终端可以在没有数据交互的情况下进入休眠状态,当接收到基站发送的唤醒信号时,开始监听下行物理控制信道(Physical Downlink Control Channel,PDCCH),以确定是否需要进入激活状态。在相关技术中,基站在每次占用非授权频段的时间段开始时刻,向存在下行数据的终端发送唤醒信号。对于某个终端,当基站某一次成功占用非授权频段的时间段的开始时刻不存在该终端的下行数据,而在本次占用非授权频段的时间段的过程中有该终端的下行数据到达时,由于终端不能在本次占用非授权频段的时间段内检测到唤醒信号,因此只能在基站下一次占用非授权频段的时间段进行下行数据接收,从而导致较高的传输时延。

无线电频谱资源是一种有限、不可再生的自然资源,因此各国对于无线电频谱有专门的管理机构,出台专门的政策法规,以实现无线电频谱的统一规划管理。目前各国的频谱管理大多数采用固定频谱分配策略,即频谱资源由政府主管部门管理并分配给固定的授权用户,这样能够确保各用户之间避免过多相互干扰,更好利用频谱资源。授权频谱受到严格的限制和保护,只允许授权用户及其符合规范的设备接入,并且用户通常要为此进行付费。目前,公安、铁路、民航、广电、电信等重要的部门均拥有一定的授权频谱,这些部门内设备的通信是运行在其授权频谱上的,尤其是电信行业,我们每天使用的手机就是通过运营商拥有的授权频谱来通信的,各大运营商都拥有各自国家的无线电管理单位或部门授权的专用频段,以保障公众移动通信不受干扰。
而非授权频谱是满足一定规范和标准的设备都可以接入和使用的频谱,但必须保证不对其他用户造成干扰。比较典型的,无线保真(Wireless Fidelity,Wi-Fi)、蓝牙(Bluetooth,BT)等通信技术就是通过非授权频谱进行传输的。此外,国际通信联盟无线电通信局曾经定义过工业科学医疗(Industrial Scientific Medical,ISM)频段,主要是开放给工业、科学、医学这三类机构使用,无需授权许可,当然也需要遵守一定的发射功率,并且不能对其它频段造成干扰。
随着新一代的增强现实(Augmented Reality,AR)/虚拟现实(Virtual Reality,VR)、车车通信等新型互联网应用的不断涌现,对于无线通信技术提出了更高的要求,驱使无线通信技术的不断演进以满足应用的需求。当下,蜂窝移动通信技术正在处于新一代技术的演进阶段。新一代技术的一个重要特点就是要支持多种业务类型的灵活配置。由于不同的业务类型对于无线通信技术有不同的要求,如增强移动宽带(enhanced Mobile Broad Band,eMBB)业务类型主要的要求侧重在大带宽,高速率等方面;超可靠低时延通信(Ultra Reliable Low Latency Communication,URLLC)业务类型主要的要求侧重在较高的可靠性以及低的时延方面;海量机器类通信(massive Machine Type Communication,mMTC)业务类型主要的要求侧重在大的连接数方面。因此新一代的无线通信系统需要灵活和可配置的设计来支持多种业务类型的传输。
随着业务需求的驱动,仅仅使用授权频谱无法满足业务的需求,因此考虑在非授权的频段上部署移动网络。目前,业内开展了将蜂窝移动通信技术扩展 到非授权频段的研究。比如,为了将第五代移动通信技术(Fifth-generation,5G)技术,也称新空口(new radio,NR)技术扩展到非授权频段上,第三代合作伙伴计划(3rd Generation Partnership Project,3GPP)组织通过了5G研究项目“Study on NR-based Access to Unlicensed Spectrum”(基于NR的非授权频谱接入研究),简称NR-U,旨在通过该项目的研究使NR能够满足非授权频段的法规要求,并且能够保证与工作在非授权频段上的其他接入技术和平共处。
在LTE的系统设计中,终端的上下行传输是基于基站的调度的。基站通过发送下行或是上行的调度信令来指示终端在相应的资源位置上以通知的方式进行数据的接收或发送。对于动态的调度来讲,一个调度信令只能指示一个传输单元(如一个子帧)上的传输。比如,请参考图1,其示出了一种LTE动态调度示意图,如图1所示,在下行传输过程中,一个传输单元为一个子帧,每个子帧中的下行控制区域用于调度该子帧内的下行数据区域。
此外,终端的续航能力是影响终端性能的重要方面。其中,终端用于控制信令检测的开销是终端耗电的重要方面。而在很多的情况下,当终端没有业务需要交互的时候,基站没有控制信令发送给终端,相应的终端做控制信令检测的时候无法检测到任何控制信令,从而浪费了大量的功率。在LTE以及NR等系统中,为了降低终端的检测开销,定义了终端的休眠状态,终端可以在没有数据交互的情况下进入休眠的状态以避免控制信令的检测,降低能量消耗。
在现有的技术中,终端在处于休眠态的时候,终端需要基于基站的配置,周期性的去监听下行控制信令或者下行数据,比如监听PDCCH中的寻呼信号(paging),以确定是否需要进入激活态。请参考图2,其示出了一种信道监听示意图,如图2所示,为了监听下行控制信令或者下行数据,在两次休眠之间,终端需要持续监听一段时间,这会使得终端消耗一定的能量。
在另外一种实现方法下,基站可以在配置终端检测Paging信息的时刻之前向终端发送一个唤醒信号,以指示是否有终端的paging信息,若终端接收到的唤醒信号,则本次启动监听下行控制信令或者下行数据,若终端没有接收到唤醒信号,则终端本次不会监听下行控制信令或者下行数据,以节约终端电量。
目前许多国家的法规要求非授权频段上的无线接入技术遵循监听避让(Listen Before Talk,LBT)机制,蜂窝移动通信技术如果想要正常在非授权频段上工作,也需要遵循LBT机制。因此,基于蜂窝移动通信技术在非授权频段上进行数据传输的过程中,基站需要在成功占用到非授权频段之后,才能 与终端进行通信,这就限制了基站向终端发送唤醒信号的时机。在相关技术中,在基于蜂窝移动通信技术使用非授权频段的过程中,基站在一个寻呼无线帧中的寻呼时刻(Paging Occasion,PO)开始之前某个时域位置发送唤醒信号,而对于某些在发送了唤醒信号之后才有业务传输的终端来讲,由于没有检测到在PO开始之前的唤醒信号,导致该终端认为没有业务的传输,因此不去检测paging信息等控制信息,导致数据传输的时延变大。
比如,请参考图3,其示出了本公开实施例涉及的一种唤醒信号发送示意图。如图3所示,基站在占用到非授权频段之后,会发送唤醒信号,终端1接收到唤醒信号之后,可以开始检测PDCCH并接收控制信息或数据信息。然而相关技术中唤醒信号仅仅在一次非授权频段的占用时间范围内的开始时刻发送,那么对于没有监听到唤醒信号的终端2来讲,只能在下一个频段占用时间内才能够去进行数据的交互,从而带来数据传输的时延。
而本公开实施例提供的方案,提供一种应用于非授权频段的终端唤醒控制方法,使得基站能够在一次占用非授权频段的时间段内,有多次唤醒终端的机会,从而缩短数据传输的时延。
本公开实施例提供一种终端唤醒控制方案,可以应用于基于蜂窝移动通信技术的无线通信系统中,实现基站对终端的寻呼。

其中,基站420可以是4G系统中采用的演进型基站(eNB)。或者,基站420也可以是5G系统中采用集中分布式架构的基站(gNB)。当基站420采用集中分布式架构时,通常包括集中单元(central unit,CU)和至少两个分布单元(distributed unit,DU)。集中单元中设置有分组数据汇聚协议(Packet Data Convergence Protocol,PDCP)层、无线链路层控制协议(Radio Link Control,RLC)层、媒体访问控制(Media Access Control,MAC)层的协议栈;分布单元中设置有物理(Physical,PHY)层协议栈,本公开实施例对基站420的具体实现方式不加以限定。
基站420和终端410之间可以通过无线空口建立无线连接。在不同的实施方式中,该无线空口是基于第四代移动通信网络技术(4G)标准的无线空口;或者,该无线空口是基于第五代移动通信网络技术(5G)标准的无线空口,比如该无线空口是新空口;或者,该无线空口也可以是基于5G的更下一代移动通信网络技术标准的无线空口。

其中,上述终端与基站之间基于非授权频段进行数据传输时,基站在一次占用非授权频段的过程中,可以有多次唤醒终端的机会。比如,请参考图5,其是根据一示例性实施例示出的一种终端唤醒控制的流程示意图。如图5所示,该终端唤醒控制的流程可以如下:

图9是根据一示例性实施例示出的终端唤醒控制方法的流程图,如图9所示,该终端唤醒控制方法应用于图4所示的无线通信系统中,且由图4中的终端410执行,该方法可以包括以下步骤。
在步骤901中,在非授权频段上接收基站发送的唤醒信号,该唤醒信号是 该基站占用该非授权频段后,在频段占用时段内的至少两个第一时间点上发送的信号;并在该非授权频段上接收该基站在该频段占用时段内的至少两个第二时间点上发送的传输结构指示信息。
其中,该频段占用时段是基站本次占用该非授权频段的时间段。该传输结构指示信息用于指示在该非授权频段上进行传输所采用的传输结构。
在步骤902中,在接收到该唤醒信号后,监听下行控制信令或者下行数据;并在接收到该传输结构指示信息后,根据该传输结构指示信息所指示的传输结构,在该基站下行传输对应的时域区间内,接收该基站发送的下行控制信令或者下行数据。
其中,上述唤醒信号可以按照第一周期进行接收,该第一周期的获取方式可以参考上述图6所示实施例中的描述,此处不再赘述。
可选的,在该非授权频段上接收该基站在该频段占用时段内的至少两个第二时间点上发送的传输结构指示信息,包括:

可选的,在获取第二周期之前,该方法还包括:

可选的,该第一周期与该第二周期相同;
或者,

在接收到所述唤醒信号时,根据所述唤醒信号的资源位置以及所述指定资源间隔,在所述非授权频段上接收所述传输结构指示信息。
综上所述,本公开实施例所示的方案,当基站支持非授权频段时,基站成功占用非授权频段后,在本次占用非授权频段的时间段内的至少两个第一时间点上,通过非授权频段向终端发送唤醒信号,使得基站在一次占用非授权频段的过程中,有多次机会唤醒终端,减少在一次占用非授权频段的过程中到来的业务对应的下行数据需要在下一次占用非授权频段成功后才能发送给终端的情况,从而缩短终端的数据传输时延。
此外,在本公开实施例所示的方案中,基站成功占用非授权频段后,在本次占用非授权频段的时间段内的至少两个第二时间点上,通过非授权频段向终端发送传输结构指示信息,以指示该基站下行传输对应的时域区间,以便终端根据该传输结构指示信息,在基站下行传输对应的时域区间内接收基站发送的信令或数据,从而进一步降低终端功耗,节约终端电量。
图10是根据一示例性实施例示出的终端唤醒控制方法的流程图,如图10所示,该终端唤醒控制方法应用于图4所示的无线通信系统中,该方法可以包括以下步骤。
在步骤1001中,基站监听非授权频段的信道状态,该信道状态包括空闲状态或者被占用状态。
在一种可能的实现方式中,基站可以检测非授权频段上的信号能量(或者信号强度),当检测到连续的一段时间内(比如连续4us内)非授权频段上的信号能量低于能量阈值,则可以认为该非授权频段当前处于空闲状态,否则,可以认为该非授权频段处于被占用状态。
在步骤1002中,基站根据对非授权频段的空闲状态的监听结果占用非授权频段。
比如,若基站监听到非授权频段当前处于空闲状态,则可以占用该非授权频段的占用,相应的,若基站监听到非授权频段当前处于被占用状态,则不占用该非授权频段,并继续监听该非授权频段的信道状态。
在步骤1003中,基站获取第一周期。
在获取第一周期时,基站可以获取预先设置的该第一周期。
在一种可能的实现方式中,基站中可以预先设置一个用于在非授权频段上发送唤醒信号的第一周期。其中,该第一周期的周期时长可以是一个固定时长,并且,该第一周期的周期时长可以由系统统一设置,或者,该第一周期的周期时长也可以由基站自行设置。
或者,在获取第一周期时,基站也可以根据预先设置的第一周期确定规则获取该第一周期。
在另一种可能的实现方式中,上述用于在非授权频段上发送唤醒信号的第一周期也可以是不固定的,基站中预先设置有一个用于获得该第一周期的第一周期确定规则,基站成功占用到非授权频段,并需要在非授权频段上发送唤醒信号时,可以根据该第一周期确定规则来获取该第一周期。
比如,该第一周期确定规则包括频段占用时段的时长与该第一周期之间的映射规则;基站需要获取第一周期时,可以根据该频段占用时段的时长,以及该频段占用时段的时长与该第一周期之间的映射规则获取该第一周期,该频段占用时段是基站本次占用该非授权频段的时间段。
或者,上述第一周期确定规则,也可以包含其它参数与第一周期之间的映射规则,比如,上述第一周期确定规则可以包含当前接入的终端数量与第一周期之间的映射规则,以及,当前接入的终端支持的业务类型与第一周期之间的映射规则等等,本公开实施例对于上述第一周期确定规则不做限定。
可选的,基站还可以向该终端发送第一周期指示信息,该第一周期指示信息包含该第一周期,或者,该第一周期指示信息包含第一周期确定规则。相应的,终端接收该基站发送的第一周期指示信息。
为了便于终端接收基站发送的唤醒信号,在本公开实施例中,基站可以向接入的终端发送第一周期指示信息,以在终端中配置上述第一周期或者第一周期确定规则。
比如,基站可以在终端接入成功后,通过下行无线资源控制(Radio Resource Control,RRC)信令、介质访问控制层控制单元(Media Access Control  Control Element)MAC CE或者物理层信令向终端发送上述第一周期指示信息。
可选的,当第一周期确定规则包括该频段占用时段的时长与该第一周期之间的映射规则,且该第一周期指示信息中包含该第一周期确定规则时,基站可以在该频段占用时段内,通过该非授权频段向该终端发送该频段占用时段的时长,相应的,终端在该频段占用时段内,通过该非授权频段接收该频段占用时段的时长。
比如,基站可以通过物理下行控制信道PDCCH,在上述频段占用时段内,通过非授权频段向终端发送该频段占用时段的时长。
可选的,在另一种可能的实现方式中,上述第一周期或者第一周期确定规则也可以预先设置在终端中,不需要基站额外进行指示。
在步骤1004中,基站在频段占用时段内,按照该第一周期在该频段占用时段内的至少两个第一时间点上,通过该非授权频段向该终端发送唤醒信号;相应的,终端按照该第一周期在非授权频段上接收基站发送的唤醒信号。
其中,该唤醒信号用于触发终端在非授权频段上监听下行控制信令或者下行数据。
在本公开实施例中,基站在一次成功占用非授权频段之后,按照上述第一周期,在该非授权频段上发送唤醒信号,而不仅仅是在频段占用时段的开始时刻在非授权频段上发送唤醒信号,相应的,终端可以获取第一周期,并按照第一周期在非授权频段上接收唤醒信号时,在一次占用非授权频段的时间段内,可以有多次接收唤醒信号的机会。
其中,终端获取第一周期的方式,与基站获取第一周期的方式类似,即终端可以获取预先设置的第一周期,或者,终端可以根据上述第一周期确定规则获取该第一周期。
可选的,当第一周期确定规则包括该频段占用时段的时长与该第一周期之间的映射规则时;终端可以接收该基站在该频段占用时段内,通过该非授权频段发送的该频段占用时段的时长;并根据该频段占用时段的时长,以及该频段占用时段的时长与该第一周期之间的映射规则获取该第一周期。终端获取到第一周期后,可以按照第一周期在非授权频段上监听唤醒信号,即终端在每次监听唤醒信号之后,若没有数据需要传输,也没有其它下行消息需要监听,则可以进入休眠状态,并在该第一周期所指示的下一次监听时间点到来时再次监听唤醒信号,不需要持续监听唤醒信号,从而达到节约终端电量的目的。
请参考图11,其示出了本申请实施例涉及的一种唤醒信号发送示意图。如图11所示,基站本次占用的非授权频段的频段占用时段包含20个时域单元,第一周期的时间长度为4个时域单元,基站在本次占用非授权频段的时间段内,每隔3个时域单元后,在下一个时域单元上发送唤醒信号,比如,在图11中,基站在频段占用时段的20个时域单元中的第1、5、9、13、17个时域单元上发送唤醒信号。
其中,上述步骤1003和步骤1004以基站按照第一周期在非授权频段上发送唤醒信号为例进行说明,在另一种可能的实现方式中,基站也可以按照周期性发送之外的其它方式,在频段占用时段内的至少两个第一时间点上发送唤醒信号。比如,基站在频段占用时段内,相邻两次发送唤醒信号的时间点之间的间隔逐渐增加或者逐渐减少。
在步骤1005中,终端在接收到该唤醒信号后,在非授权频段上监听下行控制信令或者下行数据。
通过本公开实施例所示的方案,终端在非授权频段上接收到基站周期性发送的唤醒信号之后,即可以启动在非授权频段上监听下行控制信令或者下行数据。
比如,还是以图11为例,假设终端A在图11所示的20个时域单元中的第1个时域单元之前,基站没有需要传输给该终端A的下行数据,则终端A在该第1个时域单元不会接收到唤醒信号,若在上述20个时域单元中的第3个时域单元上,有需要发送给终端A的下行数据到达基站,则基站会在第5个时域单元上向终端A发送唤醒信号,相应的,终端A在上述第5个时域单元上接收到基站发送的唤醒信号,并在非授权频段上监听基站发送的下行控制信令或者下行数据,比如,监听是否存在该终端A对应的寻呼信号。
综上所述,本公开实施例所示的方案,当基站支持非授权频段时,基站成功占用非授权频段后,在本次占用非授权频段的时间段内的至少两个第一时间点上,通过非授权频段向终端发送唤醒信号,使得基站在一次占用非授权频段的过程中,有多次机会唤醒终端,减少在一次占用非授权频段的过程中到来的业务对应的下行数据需要在下一次占用非授权频段成功后才能发送给终端的情况,从而缩短终端的数据传输时延。
图12是根据一示例性实施例示出的终端唤醒控制方法的流程图,如图12 所示,该终端唤醒控制方法应用于图4所示的无线通信系统中,该方法可以包括以下步骤。
在步骤1201中,基站监听非授权频段的信道状态,该信道状态包括空闲状态或者被占用状态。
在步骤1202中,基站根据对非授权频段的空闲状态的监听结果占用非授权频段。
其中,基站监听非授权频段并占用的过程可以参考图10对应实施例中的步骤1201以及步骤1202下的描述,此处不再赘述。
在步骤1203中,基站获取第一周期以及第二周期。
可选的,在获取第二周期时,基站可以获取预先设置的该第二周期;
或者,在获取第二周期时,基站可以根据预先设置的,用于获取该第二周期的第二周期确定规则获取该第二周期。
可选的,该第二周期确定规则包括该频段占用时段的时长与该第二周期之间的映射规则;在根据预先设置的第二周期确定规则获取该第二周期时,基站可以根据该频段占用时段的时长,以及该频段占用时段的时长与该第二周期之间的映射规则获取该第二周期。
可选的,基站还可以向该终端发送第二周期指示信息,该第二周期指示信息包含该第二周期,或者,该第二周期指示信息包含该第二周期确定规则。相应的,终端接收该第二周期指示信息。
可选的,当该第二周期指示信息中包含该第二周期确定规则时,基站还在该频段占用时段内,通过该非授权频段向该终端发送该频段占用时段的时长。相应的,终端在该频段占用时段内接收基站通过该非授权频段发送的频段占用时段的时长。
其中,上述基站获取第二周期的过程与获取第一周期的过程类似,具体实施过程可以参照图10对应实施例中获取第一周期的相关内容,此处不再赘述。
在步骤1204中,基站在频段占用时段内,按照该第一周期在该频段占用时段内的至少两个第一时间点上,通过该非授权频段向该终端发送唤醒信号;并在频段占用时段内,按照该第二周期在该频段占用时段内的至少两个第二时间点上,通过该非授权频段向该终端发送传输结构指示信息;相应的,终端按照该第一周期在非授权频段上接收基站发送的唤醒信号,并按照该第二周期在非授权频段上接收基站发送的传输结构指示信息。
其中,基站按照第一周期向终端发送唤醒信号,终端按照第一周期接收唤醒信号的相关内容,可以参考图10所示实施例中的步骤1004下的描述,此处不再赘述。
其中,该传输结构指示信息用于指示在该非授权频段上进行传输所采用的传输结构,比如,该传输结构可以指示本次占用非授权频段的时间段内,该非授权频段上的哪些时域区间可以被基站用来进行下行传输,哪些时域区间可以被终端用来进行上行传输,哪些时域区间上既不可以被基站用来进行下行传输,也不可以被终端用来进行上行传输。
对于终端来说,若能够获得基站在一次占用非授权频段的时间段内在该非授权频段上的传输结构,那么在后续接收基站发送的下行控制信号或者下行数据时可以有效的节省电量开销。比如,由于传输结构可以指示基站在哪些时域上进行下行传输,终端在检测基站的下行控制信号和/或下行数据时,可以只在传输结构所指示的,基站用来进行下行传输的时域区间内进行信号检测和接收,而在基站不用来进行下行传输的时域区间内关闭接收机,或者不进行下行信号的检测和接收,不需要全时段开启接收机,而只在基站可能发送下行信号的时间段内开启,从而达到节省终端电量开销的目的。
在相关技术中,基站可以在占用非授权频段的时间段的开始时刻,在非授权频段上发送传输结构指示信息,而在本公开实施例中,基站可以在占用非授权频段的时间段内,周期性的发送传输结构指示信息,使得终端有更多的机会能够获知剩下的频段占用时间内的传输结构。
其中,上述基站向终端发送传输结构指示信息,以及终端接收传输结构指示信息的过程,与基站和终端之间传输唤醒信号的过程类似,此处不再赘述。
可选的,该传输结构指示信息用于指示预先设置的传输结构集合中的目标传输结构,该目标传输结构是该传输结构集合中的至少一种传输结构。
在本公开实施例中,传输结构指示信息可以通过下行控制信令携带传输,其中,该传输结构指示信息可以指示预先配置的传输结构配置信息所配置的传输结构中的一种或多种。
在一种可能的实现方式中,一个频段占用时段内,不同时间上传输的传输结构指示信息指示所用的配置信息可以是相同的。在这种实现方式下,基站可以通过下行控制信令、RRC信令、MAC CE或者物理层信令通知给终端一个传输结构信息的配置集合(对应上述传输结构集合),该配置集合中包含基站可 能使用的各种传输结构;或者,上述配置集合也可以是在基站和终端中预先定义好的集合。不同时间上传输的传输结构指示信息指示该配置集合的不同配置信息集合中的配置信息,该配置信息用于指示本次占用非授权频段的剩余时间段内,或者在预先定义的时间段内,使用配置集合中的哪些传输结构。其中,该配置信息可以由基站根据业务类型进行设置。
比如,请参考图13,其示出了本申请实施例涉及的一种传输结构指示示意图,如图13所示,基站预先通知一个传输结构信息的配置集合,该配置集合中包含6种传输结构(即传输结构1至传输结构6),在一次占用非授权频段的时间段内,不同时间点上发送的传输结构指示信息指示该传输结构配置集合中不同配置子集,比如在图13中,第一次发送的传输结构指示信息指示该传输结构配置集合中的传输结构1和传输结构2,表示在本次占用非授权频段的后续时间段内,在该非授权频段上采用传输结构1或传输结构2进行上下行传输;而第二次发送的传输结构指示信息指示该传输结构配置集合中的传输结构3和传输结构4,表示在本次占用非授权频段的后续时间段内,在该非授权频段上采用传输结构3或传输结构4进行上下行传输,第三次发送的传输结构指示信息指示该传输结构配置集合中的传输结构5和传输结构6。相应的,承载传输结构指示信息的下行控制信令中,用于携带传输结构指示信息的信息域的长度可以基于配置子集的大小(即指示的传输结构的数量)而变化,比如在图13所示的方案中,只需要一个比特的信息域即可以携带传输结构指示信息,从而节省传输结构指示信息所占用的比特数。
或者,上述传输结构指示信息用于指示目标传输结构集合中的目标传输结构,该目标传输结构集合是预先设置的至少两个传输结构集合中的一个集合,该目标传输结构是所述传输结构集合中的至少一种传输结构。也就是说,一个频段占用时段内不同时间上传输的传输结构指示信息指示所用的配置信息可以是不同的。
在一种可能的实现方式中,基站可以预先通过下行控制信令通知给终端多个传输结构信息的配置集合,且不同时间上传输的传输结构指示信息指示不同的配置集合。比如,请参考图14,其示出了本公开实施例涉及的另一种传输结构指示示意图。如图14所示,基站预先向终端配置多个传输结构信息的配置集合,每个配置集合中包含至少1种传输结构;在一次占用非授权频段的时间段内,不同时间点上发送的传输结构指示信息指示这些配置集合中的一个配置 集合,比如在图14中,第一次发送的传输结构指示信息指示配置集合1以及传输结构1,该配置集合1中包含传输结构1至4,表示在本次占用非授权频段的后续时间段内,在该非授权频段上采用配置集合1中的传输结构1进行上下行传输;第二次发送的传输结构指示信息指示配置集合2以及传输结构2,该配置集合2中包含传输结构1至6,表示在本次占用非授权频段的后续时间段内,在该非授权频段上采用配置集合2中的传输结构2进行上下行传输;以此类推,第三次发送的传输结构指示信息指示配置集合3以及传输结构5,该配置集合3中包含传输结构5和6,表示在本次占用非授权频段的后续时间段内,在该非授权频段上采用配置集合3中的传输结构5进行上下行传输。
可选的,该第一周期与该第二周期相同。
比如,请参考图15,其示出了本公开实施例涉及的一种唤醒信号和传输结构指示信息的传输示意图。如图15所示,基站本次占用的非授权频段的频段占用时段包含20个时域单元,第一周期(即唤醒信号的发送周期)和第二周期(即传输结构指示信息的发送周期)的时间长度均为4个时域单元,基站在本次占用非授权频段的时间段内,每隔3个时域单元后,在下一个时域单元上发送唤醒信号或者传输结构指示信息,比如,在图15中,基站在频段占用时段的20个时域单元中的第1、5、9、13、17个时域单元上发送唤醒信号,并在频段占用时段的20个时域单元中的第2、6、10、14、18个时域单元上发送传输结构指示信息。
其中,上述图15中以唤醒信号和传输结构指示信息在不同的时域单元上进行发送为例进行说明,在实际应用中,上述唤醒信号和传输结构指示信息也可以在相同的时域单元上进行发送,比如,基站可以在上述第1、5、9、13、17个时域单元中的每个时域单元上同时发送唤醒信号和传输结构指示信息。
或者,该第一周期与该第二周期不同。
比如,请参考图16,其示出了本公开实施例涉及的另一种唤醒信号和传输结构指示信息的传输示意图。如图16所示,基站本次占用的非授权频段的频段占用时段包含20个时域单元,第一周期(即唤醒信号的发送周期)的时间长度均为4个时域单元,第二周期(即传输结构指示信息的发送周期)的时间长度均为7个时域单元,基站在本次占用非授权频段的时间段内,每隔3个时域单元后,在下一个时域单元上发送唤醒信号,并每隔6个时域单元后,在下一个时域单元上发送传输结构指示信息,比如,在图16中,基站在频段占用 时段的20个时域单元中的第1、5、9、13、17个时域单元上发送唤醒信号,并在频段占用时段的20个时域单元中的第1、8、15个时域单元上发送传输结构指示信息。
可选的,当第一周期与第二周期相同时,该唤醒信号和该传输结构指示信息之间的资源间隔为指定资源间隔;相应的,终端可以在接收到该唤醒信号时,根据该唤醒信号的资源位置以及该指定资源间隔,在该非授权频段上接收该传输结构指示信息。
其中,上述资源间隔可以包括时域间隔和频域间隔中的至少一种。即上述唤醒信号和传输结构指示信息传输的时域和/或频域间隔可以是固定的,也就是说,基站多次占用非授权频段的过程中,周期性发送的唤醒信号和该传输结构指示信息之间的资源间隔是相同的,比如,基站在一次占用非授权频段的过程中,按照固定的资源间隔发送该唤醒信号和该传输结构指示信息,在下一次占用非授权频段的过程中,还是按照该固定的资源间隔发送该唤醒信号和该传输结构指示信息。
其中,上述固定的指定资源间隔可以通过预先定义的方式在基站和终端中设置,或者,基站可以通过信令通知的方式通知终端该固定的指定资源间隔。终端在检测到唤醒信号之后,可以根据上述指定资源间隔,在相应的时频位置上接收传输结构指示信息。
其中,上述步骤1203和步骤1204以基站按照第二周期在非授权频段上发送传输结构指示信息为例进行说明,在另一种可能的实现方式中,基站也可以按照周期性发送之外的其它方式,在频段占用时段内的至少两个第二时间点上发送传输结构指示信息。比如,基站在频段占用时段内,相邻两次发送传输结构指示信息的时间点之间的间隔逐渐增加或者逐渐减少。
在步骤1205中,终端在接收到该唤醒信号后,在非授权频段上监听下行控制信令或者下行数据;并在接收到传输结构指示信息后,根据该传输结构指示信息所指示的传输结构,在基站下行传输对应的时域区间内,接收基站发送的下行控制信令或者下行数据。
综上所述,本公开实施例所示的方案,当基站支持非授权频段时,基站成功占用非授权频段后,在本次占用非授权频段的时间段内的至少两个第一时间点上,通过非授权频段向终端发送唤醒信号,使得基站在一次占用非授权频段的过程中,有多次机会唤醒终端,减少在一次占用非授权频段的过程中到来的 业务对应的下行数据需要在下一次占用非授权频段成功后才能发送给终端的情况,从而缩短终端的数据传输时延。
此外,在本公开实施例所示的方案中,基站成功占用非授权频段后,在本次占用非授权频段的时间段内的至少两个第二时间点上,通过非授权频段向终端发送传输结构指示信息,以指示该基站下行传输对应的时域区间,以便终端根据该传输结构指示信息,在基站下行传输对应的时域区间内接收基站发送的信令或数据,从而进一步降低终端功耗,节约终端电量。
