Description

确定低功耗接入或传输的方法、设备及存储介质
相关申请的交叉引用
本申请要求于2023年08月11日提交的申请号为202311014882.2,发明名称为“确定低功耗接入或传输的方法、设备及存储介质”的中国专利申请的优先权,其通过引用方式全部并入本文。
技术领域
本公开涉及通信技术领域,尤其涉及一种确定低功耗接入或传输的方法、设备及存储介质。
背景技术
终端节能议题提出了低功耗唤醒信号(Low power wake-up signal,LP-WUS)和低功耗接收机(Low Power Wake Up Receiver,LP-WUR)的概念,应用于现有节能技术的基础上进一步降低终端能耗的水平。在终端处于无线资源控制(Radio Resource Control,RRC)空闲态模式下,基站和终端没有业务传输时关闭终端耗能较大的主设备(Main Radio,MR),使得终端可以进入极低功耗状态(ultra-deep sleep state),同时开启LP-WUR设备接收基站发送的低功耗唤醒信号(Low power wake-up signal,LP-WUS)确定是否需要唤醒MR和基站进行通信,这样可以极大节省终端的功耗。
然而,MR从低功耗状态唤醒到可以正常可接收基站发送的NR信号,产生的接入时延包括:极低功耗状态到激活态的转换时延(400ms,800ms),以及MR进入激活状态后重新同步的时延(3~10个SSB周期)等。相比于现有的终端节能方法,终端进入极低功耗状态后再次唤醒的接入时延大大增加。
因此,如何减少处于极低功耗状态后的终端接入基站的时延已成为本领域亟待解决的问题。

具体地,上述第二配置信息中还配置了第二信号的类型,因此,在确定接收第二信号的资源位置的同时,也可以确定接收第二信号的类型,其中第二信号的类型包括寻呼机会和寻呼提前指示,即接收的第二信号的类型可能是寻呼机会和寻呼提前指示中任一种或组合。
此外,网络设备还会发送第三配置信息,需要基于该第三配置信息,确定第二设备优先接收哪种类型的第二信号。
进一步基于网络设备发送的第三配置信息,确定是否配置寻呼提前指示配置信息;
如果已配置寻呼提前指示配置信息,也就是网络设备指示优先接收类型为寻呼提前指示的第二信号,那么第二设备优先在所述第二信号的类型为寻呼提前指示的资源位置上,接收寻呼提前指示,再基于所述寻呼提前指示携带的信息确定是否在所述寻呼提前指示关联的寻呼机会的资源位置上,接收寻呼消息。
如果没有配置寻呼提前指示配置信息,那么第二设备直接在第二信号类型为寻呼机会的资源位置上,接收寻呼消息。
同样的,对于网络设备而言,如果第三配置信息中已配置寻呼提前指示配置信息,那么网络设备优先发送寻呼提前指示,且在该寻呼提前指示消息中携带与其关联的寻呼机会,并在对应的寻呼机会发送寻呼消息至第二设备;
如果第三配置信息中没有配置寻呼提前指示配置信息,那么网络设备直接在寻呼机会的资源位置上,发送寻呼消息至第二设备。

进一步的基于网络设备发送的第三配置信息,确定是否配置跳过参数,和/或,配置的跳过参数是否已激活;这里存在三种情况:
情况一:是否配置跳过参数;
如果配置跳过参数,那么表示这个跳过参数是起效的,该跳过参数用于指示是否跳过寻呼提前指示机会;即配置了跳过参数,表示需要跳过寻呼提示指示机会;没有配置跳过参数,表示不需要跳过寻呼提示指示机会。
情况二:是否配置跳过参数和配置的跳过参数是否已激活
如果配置了跳过参数,仅表示存在这个配置项,并不表示这个参数起效了,还需要结合配置的跳过参数是否已激活,确定这个参数是否起效。即配置了跳过参数,表示网络侧或终端侧具备这个能力,而具体是否生效需要进一步的确定跳过参数是否已激活,如果已配置跳过参数且已激活,那么表示需要跳过寻呼提示指示机会;如果已配置跳过参数且没有激活,表示不需要跳过寻呼提示指示机会。
情况三:配置的跳过参数是否已激活
和情况二类似,配置的跳过参数已激活即已配置跳过参数且已激活,配置的跳过参数未激活即已配置跳过参数且没有激活。对应的作用和效果和参见情况三中的描述。配置的跳过参数可通过动态信令进行激活或去激活。
此外,如果已配置跳过参数、配置的跳过参数已激活、或已配置跳过参数且已激活,那么第二设备在所述第二信号的类型为寻呼机会的资源位置上,接收寻呼消息;
相反地,如果未配置跳过参数、或配置的跳过参数未激活,那么第二设备优先在所述第二信号的类型为寻呼提前指示的资源位置上,接收寻呼提前指示,再基于所述寻呼提前指示携带的信息确定是否在所述寻呼提前指示关联的寻呼机会的资源位置上,接收寻呼消息。
在一些实施例中,所述第三配置信息包括以下一项或多项:

情况一:配置了该跳过参数,则表示该参数起效,即用于指示所述第二设备优先接收的所述第二信号的类型或指示跳过寻呼提前指示机会;未配置该跳过参数,则表示该参数未起效,即第二设备按照现有流程接收第二信号或指示不跳过寻呼提前指示机会。
情况二:已配置该跳过参数,不表示该参数起效,还需要激活配置的跳过参数,该跳过参数才起效。而激活配置的跳过参数的方法可以是该跳过参数中包括的一个指示位或者通过动态信令。即通过跳过参数中指示位为0或者1表示配置的跳过参数是否激活,或者,通过动态信令激活或去激活配置的跳过参数。

2)新的搜索空间(new search space,New SS)配置信息,用于配置接收第二信号的周期,起始接收位置偏移,持续时间;和现有的搜索空间相关配置参数的区别主要在于名称不同,比如现有的搜索空间配置信息的名称为PO-SS或PEI-SS,新的搜索空间配置信息的名称为PO-SS-Rel-18或PEI-SS-Rel-18;
3)第一接收窗口配置参数:在第一接收窗口内接收第二信号,第一接收窗口外不接收第二信号。相关配置参数可以包括至少如下之一:

第一接收窗口的结束时刻,可以是具体哪一帧,或者哪一个时隙,或者哪一个符号。
4)接收首个或最后一个第一信号的资源位置和接收第二信号的资源位置之间的时域偏移量LP-WUS_offset。
5)第二信号的接收次数或最大接收次数。
步骤二:基站侧根据寻呼需求发送携带唤醒信息的第一信号(LP-WUS)指示第一设备唤醒第二设备,使得第二设备处于可接收寻呼信息和/或PEI的状态,并根据第二配置信息,确定用于接收第二信号的第一接收窗口。
步骤三:第一设备(LP-WUR)接收到携带唤醒信息的第一信号(LP-WUS)后唤醒第二设备(MR),第二设备根据第一信号(LP-WUS)的接收位置确定第一接收窗口的起始位置,在第一接收窗口内确定接收第二信号(PO/PEI)的资源位置并接收。
3.1第二设备根据第一信号的接收位置确定第一接收窗口的资源位置:
第一信号的首个接收位置和/或最后一个接收位置为参考点的资源位置,与该参考点的资源位置偏移量为LP-WUS_offset的资源位置,作为第一窗口的起始位置;
进而根据第二配置信息中第一接收窗口的配置参数,以及第一窗口的起始位置,确定第一接收窗口的持续时间和终止位置;
3.2第二设备在第一接收窗口内根据第二配置信息中现有的搜索空间(search space,SS)配置信息,和/或,新的搜索空间(new search space,New SS)配置信息,确定第二信号的接收资源位置。如图3所示,图3是本公开实施例提供的在接收窗口接收第二信号的资源位置分布示意图。
步骤四:根据第三配置信息,确定优先接收的第二信号的类型;
根据第二配置信息中配置的第二信号的类型,以及上述步骤确定的接收第二信号的资源位置,可以确定在接收第二信号的资源位置上接收的第二信号的类型;第二信号的类型包括寻呼机会和寻呼提前指示。
并基于网络设备发送的第三配置信息,确定第三配置信息中是否配置了寻呼提前指示配置信息;
如果配置了寻呼提前指示配置信息,那么第二设备优先在第二信号类型为寻呼提前指示的资源位置上,接收寻呼提前指示,在基于所述寻呼提前指示携带的信息,确定是否在所述寻呼提前指示关联的寻呼机会的资源位置上,接收寻呼消息;
如果没有配置寻呼提前指示配置信息,那么第二设备在第二信号的类型为寻呼机会的资源位置上,接收寻呼消息。
或者,基于网络设备发送的第三配置信息,确定第三配置信息中是否配置跳过参数PEI_skip_enable,和/或,配置的跳过参数PEI_skip_enable是否已激活;
这里有两种情况:
情况一:是否配置跳过参数,即表示跳过参数是否起效,比如配置了跳过参数,表示跳过参数已激活了该参数;未配置跳过参数,表示跳过参数未激活;
情况二:是否配置跳过参数,并不表示跳过参数是否起效,在配置了跳过参数的前提下,还需要激活配置的跳过参数,才能确定该跳过参数起效;
如果已配置跳过参数,表示该跳过参数已起效,或者,已配置跳过参数且配置的跳过参数已激活,也表示该跳过参数已起效,或者,配置的跳过参数已激活,相当于已配置跳过参数且配置的跳过参数已激活的情况,那么第二设备在所述第二信号的类型为寻呼机会的资源位置上,接收寻呼消息;
如果未配置跳过参数,表示该跳过参数未起效,或者,已配置跳过参数且配置的跳过参数未激活,也表示该跳过参数未起效,或者,配置的跳过参数未激活,相当于已配置跳过参数且配置的跳过参数未激活的情况,那么第二设备优先在所述第二信号的类型为寻呼提前指示的资源位置上,接收寻呼提前指示,再基于所述寻呼提前指示携带的信息确定是否在所述寻呼提前指示关联的寻呼机会的资源位置上,接收寻呼消息。
例二:基于第二配置信息和接收第一信号的资源位置,确定第二设备接收第二信号的资源位置
步骤一:基站侧配置第一配置信息和第二配置信息,第一配置信息用于确定第一信号(LP-WUS)的发送和接收资源位置,第二配置信息用于确定第二信号(PO/PEI-O)的发送和接收资源位置。

步骤三:第二设备根据接收第一信号的资源位置,确定接收第二信号(PEI和/或PO)的资源位置,可以采用如下方式之一:
方式一:第二设备根据接收第一信号的资源位置和第二配置信息中新的搜索空间配置信息,确定接收第二信号的资源位置;如图4所示,图4是本公开实施例提供的接收第一信号和第二信号的资源位置分布示意图之一。
先确定接收第二信号的起始系统帧(起始寻呼帧),再在该起始寻呼帧中确定接收第二信号的符号位置,包括:
基于接收的SIB1消息,获取非连续接收周期或寻呼周期T、寻呼周期内寻呼帧的个数N和单个寻呼帧中寻呼机会的总个数Ns中的一项或多项;
获取第二配置信息中的时域偏移量,即获取参考点的资源位置和接收第二信号的资源位置之间的时域偏移量,其中参考点的资源位置为第一设备接收首个第一信号的资源位置或接收最后一个第一信号的资源位置;
确定参考点对应的资源位置所在的系统帧;
确定第一输入参数为非连续接收周期或寻呼周期T、寻呼周期内寻呼帧的个数N、参考点对应的资源位置所在的系统帧、第二配置信息中的时域偏移量中的任一项或多项;
按照第一规则,以及第一输入参数,确定接收第二信号的起始资源位置所在的系统帧,作为目标寻呼帧。寻呼机会所在的系统帧为寻呼帧,对应的确定接收第二信号的起始资源位置所在的系统帧,即目标寻呼帧。第一规则用于定义不同输入参数和接收第二信号的起始资源位置所在的系统帧之间的对应关系。
在目标寻呼帧中,基于索引计算规则,以及第二输入参数,确定接收所述第二信号的符号位置对应的目标索引值;这里的第二输入参数包括第二设备的标识、所述寻呼周期内寻呼帧的个数N、单个寻呼帧中寻呼机会的总个数Ns中的一项或多项;索引计算规则用于定义不同的输入参数和接收第二信号的符号位置对应的索引值之间的关系。
根据SIB1中配置的起始接收符号位置集合firstPDCCH-MonitoringOccasionOfPO,确定与所述目标索引值匹配的寻呼机会;将所述寻呼机会作为接收第二信号的资源位置。
在一些实施例中,第一规则满足公式:
(LP-WUS_SFN+LP-WUS_offset+SFN)mod T=T div N;
其中,LP-WUS_SFN表示参考点的资源位置所在的系统帧(SFN),参考点的资源位置为接收首个/最后一个第一信号的资源位置;
LP-WUS_offset表示参考点对应的资源位置与所述第二设备接收第二信号的资源位置之间的时域偏移量,通过第二配置信息配置;

N表示寻呼周期内寻呼帧的个数,通过SIB1消息配置。
在一些实施例中,所述索引计算规则对应的公式为:
i_s=floor(UE_ID/N)mod Ns;
其中,UE_ID表示第二设备的标识;N表示寻呼周期内寻呼帧的个数,floor()表示向下取整,mod()表示取模,Ns是单个寻呼帧在寻呼机会的个数;i_s表示接收所述第二信号的符号位置对应的目标索引值。
寻呼机会(PO)关联的寻呼提前指示(Paging Early Indication,PEI)的起始接收位置通过现有SIB1消息中的pei-FrameOffset和firstPDCCH-MonitoringOccasionOfPEI-O配置参数确定。
方式二:未接收到SIB1消息,根据第二配置信息中新的搜索空间配置信息,以及接收第一信号的资源位置,确定接收第二信号的资源位置。
接收第二信号的起始资源位置距离接收首个/最后一个第一信号的资源位置的时域偏移LP-WUS_offset,其中LP-WUS_offset单位可以是帧/时隙(slot)/符号(symbol);
确定接收第一信号的资源位置所在的系统帧,作为第一系统帧;
在第一系统帧中,按照第二配置信息中第二搜索空间配置信息配置的第二周期以及第二配置信息中的时域偏移量,依次确定接收所述第二信号的资源位置。
其中第二搜索空间配置信息主要用于配置在单个系统帧中周期性确定接收第二信号的时隙位置或确定接收第二信号的符号位置。具体是时隙位置还是符号位置,基于接收第一信号的资源位置的粒度确定,如果接收第一信号的资源位置是以时隙为单位,那么接收第二信号的资源位置也是以时隙为单位,如果接收第一信号的资源位置是以符号为单位,那么接收第二信号的资源位置也是以符号为单位。从而确定了接收第二信号的资源位置。
步骤四:根据第三配置信息,确定优先接收的第二信号的类型;具体的实现过程和例一中相同,在此不再赘述。
例三:在第二配置信息中还配置了与第一信号关联的用于接收第二信号的第四持续时长的情况下,直接根据第二配置信息,确定接收第二信号的资源位置。

步骤二:基站侧根据寻呼需求发送携带唤醒信息的第一信号(LP-WUS)指示第一设备唤醒第二设备,第二设备处于可以接收第二信号的状态,发送第二信号的资源位置距离发送第一信号的资源位置的时域偏移量为LP-WUS_offset。
步骤三:基于第二配置信息中第一搜索空间配置信息,先确定接收第二信号的资源位置,再根据与第一信号关联的用于接收第二信号的第四持续时长,确定接收第一信号的资源位置,具体包括:
获取第二配置信息中第一搜索空间配置信息的第一周期;
在每个第一周期内,以每个周期的起始时刻为起点,按照第二配置信息中的时域偏移量,依次确定接收第二信号的资源位置;
基于所述第二配置信息中所述第四持续时长和所述时域偏移量,以及接收目标第二信号的资源位置,确定接收所有所述第一信号的资源位置;如图5所示,图5是本公开实施例提供的接收第一信号和第二信号的资源位置分布示意图之二。

步骤四:根据第三配置信息,确定优先接收的第二信号的类型;具体的实现过程和例一中相同,在此不再赘述。
在接收第一信号的资源位置上,先接收第一信号,再在接收第二信号的资源位置上,接收第二信号。
在开始接收第一信号的同时,统计接收的第一信号的次数是否达到第一配置信息中配置的第一信号的重复传输次数或最大传输次数,如果达到,那么不再继续接收第一信号,如果没有达到,那么继续接收第一信号。
同样的,在开始接收第二信号的同时,统计未接收到第二信号的连续次数,是否达到第二配置信息中配置的第二信号的最大接收次数,如果达到,那么第二设备再次进入休眠状态,如果没有达到,那么第二设备继续接收第二信号。
此外,第一设备和第二设备具有关联关系,可以获知对方的接收能力信息,并由第一设备、第二设备或第一设备和第二设备上报接收能力信息,网络设备基于接收到的接收能力信息,确定第一配置信息,第二配置信息以及第三配置信息。
