对于NR***来说,RRC_IDLE或RRC-Inactive模式下节电与接收鲁棒性优化也很重要。对于RRC_IDLE或RRC-Inactive的终端,基站不知道UE驻留在哪个基站,如果对于跟踪区(Tracking Area,TA)或基于无线(访问)接入网(Radio Access Network(Access Network),RAN)的通知区域(RAN-based Notification Area,RNA)内的UEs,基站或核心网会发送寻呼(paging)信号唤醒UEs进入RRC-Connected模式接收数据,或者去接收***信息无线网络临时标识(Radio Network Tempory Identity,RNTI)(System information-RNTI,SI-RNTI)加扰的***信息更新。因此,对于RRC_IDLE或RRC_Inactive模式,UE会接收寻呼与***信息(System Information,SI)。 对于寻呼消息,基站会为终端配置UE专用的非连续接收(Discontinuous Reception,DRX)周期;从终端的视角,每隔一个DRX周期,终端会有一次监听寻呼的机会。而寻呼消息由paging下行控制信息(Downlink control Information,DCI)与Paging物理下行共享信道(Physical Downlink Shared Channel,PDSCH)构成。
在激活时间(Active Time)下,终端除了可以接收同步信号块(Synchronization Signal Block,SSB)之外,基站还为UE配置信道状态信息参考信号(Channel State Information Reference Signal,CSI-RS)和/或时频跟踪参考信号(Tracking Reference Signal,TRS)。当前技术中,基站为连接态UE配置CSI-RS或TRS可能伴随着连接态UE传输完毕,会很快的去激活CSI-RS/TRS的发送,从而导致基站为空闲态的UE配置的参考信号(Reference Signal,RS)资源未必存在RS的发送,对于空闲态或非激活态的UE,并不能准确获知参考信号资源上是否存在参考信号,增加了UE的盲检操作,进而增加了空闲态或非激活态UE的功耗。

作为一个可选实施例,网络侧设备通过物理层信令显示指示所述第一信令的信令类型,包括:
网络侧设备通过物理层信令包括的可获得性字段的至少一比特(bit或bitmap)或至少一码点(code point),显示指示所述第一信令的信令类型。
例如通过物理层信令的可获得字段的第一比特或码点显式指示第一信令的信令类型为物理层信令或高层信令。
若物理层信令的可获得性字段的第一比特或code point为第一预设值,则第一信令的信令类型为物理层信令,则终端根据物理层信令确定第一传输资源上的参考信号可获得性;
若物理层信令的可获得性字段的第一比特或code point为第二预设值,则第一信令的信令类型为高层信令,则终端根据高层信令(如SI)确定第一传输资源上的参考信号可获得性。
作为另一个可选实施例,所述网络侧设备通过物理层信令包括的可获得性字段的至少一比特或至少一码点,显示指示所述指示信令的信令类型之前,所述方法还包括:

可选地,该物理层信令为寻呼提前指示(Paging Early Indication,PEI)信令,和/或,寻呼下行控制信息(Downlink control Information,DCI)。
例如,网络侧设备向第一终端发送PEI或寻呼DCI,如果其PEI或寻呼DCI均没有配置参考信号可获性指示字段,则该PEI或寻呼DCI隐式指示第一信令的信令类型为高层信令,也可以称为该PEI或寻呼DCI隐式指示终端根据高层信令确定参考信号可获得性;如果其PEI或寻呼DCI配置了参考信号可获得性指示字段,则隐式指示第一信令的信令类型为物理层信令,也可以称为该PEI或寻呼DCI隐式指示终端根据物理层信令(PEI或寻呼DCI)确定参考信号可获得性。
在本公开的至少一个实施例中,步骤202中网络侧设备通过物理层信令向所述第一终端指示第一信令的信令类型,包括:
网络侧设备通过物理层信令包括的第一指示域,指示至少一个传输资源集对应的第一信令的信令类型;
例如,第一指示域为第一值,指示第一传输资源集对应的第一信令的信令类型为高层信令,第二传输资源集对应的第一信令的信令类型为物理层信令;
或者,步骤202中网络侧设备通过物理层信令向所述第一终端指示第一信令的信令类型,包括:
网络侧设备通过物理层信令包括的至少两个第二指示域,分别指示对应的传输资源集的第一信令的信令类型;
其中,所述第一信令用于指示对应的传输资源集的参考信号可获得性。
例如,物理层信包括两个第二指示域;一个第二指示域为第一值,指示第一传输资源集对应的第一信令的信令类型为高层信令;另一个第二指示域为第二值,指示第二传输资源集对应的第一信令的信令类型为物理层信令。
可选地,物理层信令至少可利用第一指示域激活或者关闭对第一传输资源集对应的基于高层信令的参考信号可获得性指示:
如果第一指示域为第一预设值,则终端在第一传输资源集,采用高层信令(如SI)确定第一传输资源集对应的参考信号可获得性;且终端在第二传输资源集,采用物理层信令确定第二传输资源集对应的参考信号可获得性。
如果第一指示域为第二预设值,则终端采用物理层信令确定第三资源集对应的参考信号可获得性。其中第三资源集包括第一资源集和第二资源集。
作为一个可选实施例,所述方法还包括:
网络侧设备通过高层信令为所述第一终端配置第一指示域和/或第二指示域在所述物理信令中的位置信息。
例如,网络侧设备通过SI为第一终端配置第一指示域和/或至少一个第二指示域在所述物理信令中的位置信息,该位置信息包括比特位置或者对应的code point。则第一终端根据对应的高层信令可以确定第一指示域和/或第二指示域的位置,从而准确确定第一信令的信令类型。
在本公开的至少一个实施例中,所述方法还包括:
所述网络侧设备根据第一终端所处的频率范围,确定所述物理层信令和/或高层信令中用于参考信号可获得性指示的比特数目。
需要说明的是,第一频率范围,如FR1是指5G Sub-6GHz(6GHz以下)频段,第二频率范围,如FR2则是5G毫米波频段。

较佳的,第一数值等于1。
本公开实施例中,当FR2时,终端支持多个接收波束,且终端经过睡眠醒来时,往往无法失去原来的最佳波束配对,因此第一数值为1时网络侧设备为终端发送多个波束的TRS,利于终端实现信道追踪(channel tracking)。
作为另一个可选实施例,所述网络侧设备根据第一终端所处的频率范围,确定所述物理层信令和/或高层信令中用于参考信号可获得性指示的比特数目,包括:
在所述频率范围为第一频率范围(如FR1)的情况下,确定所述物理层信令和/或高层信令中用于参考信号可获得性指示的比特数目大于或等于1。
可选地,物理层信令的每个用于参考信号可获得性指示的比特指示的传输资源集,或者每个code point指示的传输资源集,仅对应相同的发送波束;
或者,物理层信令的每个用于参考信号可获得性指示的比特指示的传输资源集,或者每个code point指示的传输资源集,分别对应一组发送波束。
本公开实施例中,当FR1,由于终端支持全向接收,即使基站配置一个波束的TRS,终端大概率可以实现正常接收,从而按照波束指示接收TRS,利于基站侧降低TRS的发送开销。

例如,该高层信令为SI,如***信息块(System Information Block,SIB)-X。
网络侧设备利用第一SI为第一终端配置第一传输资源集和第二传输资源集,网络侧设备进一步利用第二SI(该第二SI与第一SI可以为同一个SI,也可以为不同的SI)指示第二传输资源集上物理层信令指示的激活信息,进一步利用第三SI(该第三SI与第二SI可以为同一个SI,也可以为不同的SI)指示第一传输资源物理层信令指示的去激活信息。
则终端根据高层信令的指示确定第一传输资源集对应的参考信号可获得性;终端根据物理层信令的指示确定第二传输资源集对应的参考信号可获得性。
在本公开的至少一个可选实施例中,步骤202中网络侧设备通过物理层信令和/或高层信令向所述第一终端指示至少一个传输资源集分别对应的参考信号可获得性,包括:

作为一个可选实施例,网络侧设备通过物理层信令包括的N1个可获得性指示比特或者N2个码点,分别指示各个传输资源集对应的参考信号可获得性之前,所述方法还包括:
网络侧设备通过高层信令指示每个传输资源集与物理层信令中的可获得性指示比特的对应关系;
或者,
网络侧设备通过高层信令指示每个传输资源集与物理层信令中的码点的对应关系。
例如,网络侧设备利用高层信令(如SI)指示每个传输资源集与物理层信令中的可获得性指示比特或码点的对应关系,则终端能够根据可获得性指示比特或码点确定各个传输资源集的参考信号可获得性。
在本公开的至少一个实施例中,每个传输资源集对应发送波束全集;例如,网络侧设备在物理层信令中配置多个比特,每个比特用于指示一个传输资源集合的参考信号可获得性,该传输资源集是第一传输资源的子集,该传输资源集对应发送波束的全集;
或者,每个传输资源集对应发送波束全集的一个子集,一个子集包括至少一个相邻的波束对;不同的传输资源集之间存在重叠发送波束;
其中,所述发送波束全集包括:所述第一传输资源对应的所有发送波束。

其中,所述第一信令指示的参考信号可获得性在所述第一信令的生效时间内生效。

作为一个可选实施例,网络侧设备通过物理层信令和/或高层信令向所述第一终端指示第一信令的生效时间,包括:
网络侧设备通过高层信令向所述第一终端指示所述第一信令的生效时间;
或者,
网络侧设备通过高层信令向所述第一终端设备指示所述第一信令的生效时间集合,并通过物理层指示所述生效时间集合中的生效时间;例如,基站通过SIB-X为终端配置至少一个validate timer值,基站通过寻呼DCI指示实际采用的validate timer值。
作为另一个可选实施例,所述生效时间与所述参考信号的位置相关联;其中,参考信号不同的位置对应不同生效时间;
例如,PEI指示的参考信号可获得性对应的生效时间与参考信号位置相关联,参考信号不同的位置具有不同的生效时间或生效区间。
例如,参考信号位于PEI与寻呼机会(Paging Opportunity,PO)之间,PEI生效范围是当前DRX周期,参考信号位于PO之后其生效范围至少是下一个DRX周期,或者有效定时器=0。
或者,所述生效时间与指示参考信号可获得性的物理层信令和/或高层信令的位置相关联;
可选地,在网络侧设备配置的第一传输资源与指示参考信号可获得性的物理层信令和/或高层信令的位置之间的距离超过第一门限值的情况下,所述生效时间为0。
例如,网络侧设备通过SI通知第一门限值或者通过标准预定第一门限值,当网络侧设备配置的第一传输资源距离目标位置(即指示参考信号可获得性的物理层信令和/或高层信令的位置)超过该第一门限值,则该物理层信令和/或高层信令指示的参考信号可获得性的有效定时器的取值为0,即终端不希望该第一传输资源用于目标位置对应的信道跟踪操作。
作为又一个可选实施例,物理层信令或高层信令指示的参考信号可获得 性时相对应的生效时间的个数是第一信令的信令类型的函数,或者与第一信令的信令类型相关联;

作为另一个可选实施例,所述生效时间与所述参考信号的位置相关联;其中,参考信号不同的位置对应不同生效时间;
例如,PEI指示的参考信号可获得性对应的生效时间与参考信号位置相关联,参考信号不同的位置具有不同的生效时间或生效区间。
例如,参考信号位于PEI与寻呼机会PO之间,PEI生效范围是当前DRX周期,参考信号位于PO之后其生效范围至少是下一个DRX周期,或者有效定时器=0。

可选地,在网络侧设备配置的第一传输资源与指示参考信号可获得性的物理层信令和/或高层信令的位置之间的距离超过第一门限值的情况下,所述生效时间为0。
例如,网络侧设备通过SI通知第一门限值或者通过标准预定第一门限值,当网络侧设备配置的第一传输资源距离目标位置(即指示参考信号可获得性的物理层信令和/或高层信令的位置)超过该第一门限值,则该物理层信令和/或高层信令指示的参考信号可获得性的有效定时器的取值为0,即终端不希望该第一传输资源用于目标位置对应的信道跟踪操作。
作为又一个可选实施例,物理层信令或高层信令指示的参考信号可获得性时相对应的生效时间的个数是第一信令的信令类型的函数,或者与第一信令的信令类型相关联;

例如,基站利用物理层信令显示指示物理层信令指示的validate timer过期后,是否采用SIB信令指示参考信号可获得性:
若物理层信令承载的default_TRS_configuration=1,当L1信令指示失效后,终端根据SI信令指示确定TRS availability;

为了更清楚的描述本公开实施例提供的信息指示方法及信息获取方法,下面结合几个示例进行说明。
示例一
步骤1,网络侧设备配置第一传输资源;基站通过高层信令(例如***信息SIB-X)为RRC idle/inactive UE配置CSI-RS/TRS的发送资源。
步骤2,通过物理层信令向所述第一终端指示第一信令的信令类型;包括方案1,方案2,方案3以及方案4。
其中,方案1:
基站利用物理层信令显式指示终端,根据高层信令(优选地,SI信令)还是物理层信令确定第一传输资源上对应的参考信号可获得性(RS availability)。较佳的,上述显式指示为物理层信令采用bitmap或者code point方式指示确定参考信号可获得性的信令类型。较佳的物理层信令(例如,层1信令)为PDCCH,例如为paging DCI或者基于PDCCH的(PDCCH based)PEI,paging DCI存在6比特的预留bits,其中至少一个比特或者一个code point可以用于指示确定参考信号可获得性的信令类型,PDCCH based PEI对应的DCI中至少有一个比特或者一个code point可以用于指示终端确定参考信号可获得性的信令类型。
通过物理层信令显示指示第一信令的信令类型之前,基站利用高层信令(较佳的,***信息)为终端配置指示参考信号可获得性字段在L1信令中的位置,至少包括该字段在DCI中的起始点信息与占据的长度,其中至少一个比特或者一个code point用于确定指示参考信号可获得性的信令类型,其他比特或者code point用于确定具体的参考信号可获得性。例如,参考信号可获得性字段的第一个可用比特或者code point可以用于确定指参考信号可获得性的信令类型。
可选地,基站利用L1信令为终端配置指示参考信号可获得性的SI信令和/或L1信令生效或者生效时间,其中SI或者L1信令仅在基站所配置的validate timer内生效。
当指示参考信号可获得性的字段的第一个可用比特/code point为第一预设值(如为1),则基站指示终端根据层1信令确定第一传输资源上对应的CSI-RS/TRS的availability;
当指示参考信号可获得性的字段的第一个可用比特/code point为第二预设值(如为0),则指示终端根据高层信令(如SI)确定第一传输资源上对应的CSI-RS/TRS的availability。
可选地,当层1信令指示终端采用SI确定第一传输资源上对应的CSI-RS/TRS的availability时除了上述指示信令类型的比特,availability的字段内的其他比特为全0比特。
可选地,当层1信令指示终端采用SI确定第一传输资源上对应的CSI-RS/TRS的availability时除了上述指示信令类型的比特,可选地availability的字段内的其他比特用于指示SI信令的有效或者生效时间。对终 端来说,SI仅在L1信令配置的validate timer内生效。
可选地,基站与终端预先约定availability指示的默认模式,例如,预先约定根据L1信令指示确定CSI-RS/TRS的availability。所述默认模式为没有L1信令指示TRS availability时,所配置参考信号发送机会对应的TRS availability。
上面举例主要描述的是基于PDCCH的层1信令,所述层1信令/信道还包括基于序列的信号,例如基于序列的(sequence based)PEI,此时sequence based PEI可以采用不同的code point对应不同序列或者不同传输资源的方式用于指示CSI-RS/TRS的availability的信令类型。
方案1的有益效果在于:相关技术高层信令半静态配置指示CSI-RS/TRS的availability的信令类型为SI还是层1信令。缺陷在于***信息配置变化很慢,频繁接收***消息更新具有很高的终端功耗,所以只有在CSI-RS/TRS变化缓慢场景下,SI指示CSI-RS/TRS的availability才会非常有效的UE节能效果;如果连接态参考信号是快速变化的,此时采用L1信令指示CSI-RS/TRS的availability可能会为UE提供很小的节能增益,但是可以让UE避免频繁读取TRS更新触发的SI更新。对于实际大多数场景,基站并不能长时间的预测连接态业务的类型及其传输特征(只有极少极端场景才能确定肯定会采用慢变的CSI-RS/TRS),此时只能配置层1信令如paging DCI指示,由于paging DCI仅在存在寻呼消息时才被发送,所以当TRS实际是缓慢变化时利用paging DCI信令指示CSI-RS/TRS的availability会导致额外的Paging DCI信令开销,另一方面TRS慢变时,如果缺少paging DCI指示CSI-RS/TRS的availability,终端不能被指示为该CSI-RS/TRS资源上存在TRS,从而无法利用TRS节能。所以本公开的利用L1信令指示终端灵活切换指示CSI-RS/TRS的availability的类型有利于终端节能与基站侧开销的降低。同时可以实现,不必采用***消息更新的方式就可以实现***消息指示与L1信令指示的切换,不但为基站提供更高的灵活性,同时基站侧不需要频繁读取***消息,实现终端节能。
方案2:
基站利用物理层信令显式指示,第一CSI-RS/TRS资源/资源集采用SI信 息指示其对应的RS availability,第二CSI-RS/TRS资源/资源集或第三CSI-RS/TRS资源/资源集采用L1信令指示其对应的RS availability。较佳的例如,基站通过SIB-X配置至少两个CSI-RS/TRS资源/资源集,分别是第一CSI-RS/TRS资源/资源集与第二CSI-RS/TRS资源/资源集,而第一CSI-RS/TRS资源/资源集与第一CSI-RS/TRS资源/资源集构成第三CSI-RS/TRS资源/资源集。
L1信令的显式的bitmap或者code point分别指示不同的CSI-RS/TRS资源/资源集对应的RS availability。具体如下:
基站利用高层信令(较佳的为***信息)为终端配置指示CSI-RS/TRS的availability的字段在L1信令中的位置。例如,基站利用***信息配置第一CSI-RS/TRS资源/资源集对应的CSI-RS/TRS availability指示比特在L1信令的CSI-RS/TRS availability指示字段中的位置;基站利用***信息配置第二CSI-RS/TRS资源/资源集对应的CSI-RS/TRS availability指示比特在L1信令的CSI-RS/TRS availability指示字段中的位置。所述位置信息较佳的包括位置起始点及其占用的比特长度或者code point的范围。
可选地,L1信令(如paging DCI)中CSI-RS/TRS availability指示字段包括N比特,其中第一指示N1个比特,例如N1=1用于指示第一CSI-RS/TRS资源/资源集对应的CSI-RS/TRS availability,第二指示N2个比特用于指示第二CSI-RS/TRS资源/资源集或者第三资源/资源集对应的CSI-RS/TRS availability。
L1信令至少可以利用第一指示N1=1比特(SI_ON_OFF)激活或者关闭对第一CSI-RS/TRS资源/资源集对应的SI指示CSI-RS/TRS availability。
如果SI_ON_OFF=1,则终端在第一CSI-RS/TRS资源/资源集,采用SI信令确定第一CSI-RS/TRS资源/资源集对应的CSI-RS/TRS availability;且终端在第二CSI-RS/TRS资源/资源集,采用L1信令确定第一CSI-RS/TRS资源/资源集对应的CSI-RS/TRS availability。
如果第一指示SI_ON_OFF=0,则终端采用L1信令确定第三CSI-RS/TRS资源/资源集对应的CSI-RS/TRS availability。可选地,基站利用第二指示比特和/或第二指示比特,指示第三CSI-RS/TRS资源/资源集对应的CSI-RS/TRS availability。
该方案2的有益效果在于:由于CSI-RS/TRS资源/资源集来自于连接态UE,不同的UE往往对应不同的CSI-RS/TRS资源,经常会导致基站为部分连接态UE配置的CSI-RS/TRS资源可能变化缓慢属于半静态的周期性CSI-RS/TRS资源,另外一部分CSI-RS/TRS资源对应的可能是快速变化的CSI-RS/TRS资源,同时不排除还存在一部分资源在一段时间内对应的是不变/慢变的CSI-RS/TRS资源,另外一段时间内对应的快速变化的CSI-RS/TRS。本公开实施例对不同特征的CSI-RS资源进行了进一步的区分,较佳的对较大概率慢变的第一CSI-RS/TRS资源采用SI指示CSI-RS/TRS availability,在大概率变化较快的第二CSI-RS/TRS资源采用L1信令指示CSI-RS/TRS availability,当第一CSI-RS/TRS资源的SI指示被动态去激活后,则所有的第三CSI-RS/TRS资源都采用L1信令指示CSI-RS/TRS availability,这样灵活指示不同的特征的CSI-RS资源,达到减低基站信令开销,降低终端功耗的目的。
方案3:
基站同时在相同第一传输资源上配置SI与L1信令共同指示,基站通过L1信令显示配置L1信令validate timer过期后,或者当L1信令不再有效时,是否采用SIB信令指示TRS availability。
较佳的L1信令存在至少1比特的bitmap或者code point(如default_TRS_configuration)。如果default_TRS_configuration=1,则表示L1信令过期后,采用SIB信令指示第一传输资源上对应的CSI-RS/TRS availability;如果default_TRS_configuration=0,则表示L1信令过期后,第一传输资源上不存在CSI-RS/TRS。
更具体的,基站同时在相同第一传输资源上配置SI与L1信令共同指示CSI-RS/TRS availability,当default_TRS_configuration=1时,默认的TRS availability指示方式为SI,而L1信令则在SI信令基础上更新TRS availability指示,此时终端根据L1信令确定TRS availability指示,当L1信令指示失效时,则根据SI信令指示确定TRS availability;当default_TRS_configuration=0时,一旦L1信令失效,UE假定对应的第一传输资源上不存在CSI-RS/TRS。
方案4:
基站利用物理层信令隐式指示终端根据SI确定CSI-RS/TRS传输机会上的CSI-RS/TRS的availability。具体为:基站发送L1信令指示TRS availability,如果其paging DCI比特或者PEI比特都没有配置TRS availability指示字段,则隐式指示终端采用SI信令指示TRS availability;如果L1信令如paging DCI或者PEI配置TRS availability指示字段或者code point则采用L1信令指示第一传输资源上对应的CSI-RS/TRS availability。
示例二
基站利用SI(如SIB-X)为终端配置第一CSI-RS/TRS资源/资源集与第二CSI-RS/TRS资源/资源集。基站利用***消息指示第二CSI-RS/TRS资源/资源集上L1信令指示的激活信息,基站利用***消息指示第一CSI-RS/TRS资源/资源集上L1信令指示的去激活信息。
则终端根据SI信令指示确定第一CSI-RS/TRS资源/资源集上对应的CSI-RS/TRS availability;终端根据L1信令指示确定第二CSI-RS/TRS资源/资源集上对应的CSI-RS/TRS availability。
该示例有益效果在于:由于CSI-RS/TRS资源/资源集来自于连接态UE,不同的UE往往对应不同的CSI-RS/TRS资源,经常会导致基站为部分连接态UE配置的CSI-RS/TRS资源可能变化缓慢属于半静态的周期性CSI-RS/TRS资源,另外一部分CSI-RS/TRS资源对应的可能是快速变化的CSI-RS/TRS资源。本公开,对不同特征的CSI-RS资源进行了进一步的区分,较佳的对较大概率慢变的第一CSI-RS/TRS资源采用SI指示CSI-RS/TRS availability,在大概率变化较快的第二CSI-RS/TRS资源采用L1信令指示CSI-RS/TRS availability,达到减低基站信令开销,降低终端功耗的目的。
示例三
基站利用SI配置至少一个CSI-RS/TRS资源集合,每个CSI-RS/TRS资源集合中CSI-RS/TRS资源的发送波束至少与1个SSB相关联。SI信令指示上述每个CSI-RS资源集合或者所有CSI-RS资源集合或者部分CSI-RS资源集合对应的TRS availability指示比特在L1信令中对应的位置,或者SI信令指示每个CSI-RS资源集合或者所有CSI-RS资源集合或者部分CSI-RS资源集合对应的code point。
L1信令的每个CSI-RS/TRS availability指示比特,或者code point指示对应的传输资源集对应的CSI-RS/TRS availability,具体为:
L1信令的每个CSI-RS/TRS availability指示比特,或者每个code point指示的CSI-RS/TRS资源集合仅对应相同的发送波束。
或者,
L1信令的每个CSI-RS/TRS availability比特,或者每个code point指示的CSI-RS/TRS资源集合对应所有发送波束,所述所有发送波束是基站通过SI信令配置的所有CSI-RS/TRS资源对应的发送波束的全集。较佳的,基站在L1信令中配置多个比特,每个比特用于指示一个CSI-RS/TRS资源集合,该CSI-RS/TRS资源集合是基站为CSI-RS/TRS场合(occasion)通过SI信令配置的所有CSI-RS/TRS资源的子集,该CSI-RS/TRS资源集合对应发送波束的全集。
或者,
L1信令的每个CSI-RS/TRS availability比特,或者每个code point指示的CSI-RS/TRS资源集对应一组发送波束,所述一组发送波束,是发送波束全集的一个子集,所述发送波束全集是基站通过SI信令配置的所有CSI-RS/TRS资源对应的发送波束的全集。所述每个比特或者每个code point指示的CSI-RS/TRS资源集合对应一组送波束:L1信令每个比特或者每个code point对应的一组送波束包含至少一个相邻的发送波束对。此处相邻发送波束对的含义较佳的是,基站通过SI信令配置的所有CSI-RS/TRS资源对应的发送波束中两个相邻的发送波束,如图4所示,当然也不排除与两个相邻SSB对应的发送波束对这种特殊情况。较佳的,如图4所示,相同比特指示的CSI-RS资源集合在集合内部存在相邻的波束对,在不同比特指示的CSI-RS/TRS资源集合间,还存在重叠发送波束,当然重叠发送波束对应的CSI-RS资源较佳的是不同的CSI-RS资源。
该示例的有益效果为:连接态基站为终端配置的CSI-RS资源一般是根据波束配置的,比如虽然CSI-RS是终端专用配置的,但是基站可以为不同的终端共享相同发送波束的CSI-RS/TRS降低基站侧开销。当连接态TRS用于空闲态UE时,L1信令按照波束选择的方法指示,TRS资源利于基站侧开销降 低;另外L1信令每个比特对应多个发送波束指示利于用较少的L1信令比特支持最多64个发送波束,从而利于终端节能。本方案的有益效果更主要在于:终端在空闲态下从睡眠状态醒来时,由于位置的变化,终端无法确定是否还在原波束的覆盖之下,本公开实施例的方法,每个比特指示的CSI-RS资源集合包含了所有发送波束利确保了终端可以利用TRS节能;同时可选地,基站侧可以为每个比特对应的CSI-RS集合配置多个相邻的发送波束,相同比特对应的CSI-RS资源内部为相邻波束,不同比特对应的CSI-RS资源集合间存在重叠发送波束,利于解决终端由于睡眠导致的无法确定可以采用的发送波束问题。
示例四
基站配置SI和/或L1信令指示CSI-RS/TRS availability,基站利用SI信令配置或者预先约定或者隐式配置的方法为终端配置上述SI和/或L1信令对应的validate timer。当采用信令配置时,较佳的可在配置CSI-RS/TRS资源的SIB-X内配置validate_timer_SIB和/或validate_timer_L1;当采用预先约定方法时,较佳的通过标准预先规定的方法预定,当采用隐式配置时可以基于L1信令发送资源及其TRS发送资源进行隐式指示。
基站为终端配置SI和/或L1信令指示CSI-RS/TRS availability,SI和/或L1信令对应的validate timer:物理层信令/SI信令指示的TRS availability对应的validate timer是TRS位置的函数,或者与L1信令的位置相关联。
例如,基站利用高层信令为PEI配置第一validate timer值T1,基站为paging DCI配置第二validate timer值T2,PEI位置总是在Paging DCI之前,较佳的第一validate timer值T1<=第二validate timer值T2或者第一validate timer值T1<=第二validate timer值T2且第一validate timer值T1大于等于一个DRX周期。
有益效果在于:为PEI定义一个至少为一个DRX周期的第一validate timer值虽然对paging接收没有增益,但是可以利于空闲态其他数据传输节能,例如空闲态传输的多媒体广播业务,或者空闲态传输的小数据(small data)。第一validate timer值T1<=第二validate timer值T2利于基站侧开销降低。
PEI指示CSI-RS/TRS availability对应的validate timer与CSI-RS/TRS位 置相关联,CSI-RS/TRS不同的位置具有不同的validate timer值,或者生效区间。
CSI-RS/TRS位于PEI与PO之间,PEI生效范围是当前DRX周期;CSI-RS/TRS位于PO之后其生效范围是至少是下一个DRX周期(例如可以包含当前DRX周期与下一个或者下N个DRX周期),或者CSI-RS/TRS对应的validate timer=0。
L1信令指示的CSI-RS/TRS availability,基站通过SI通知一个门限值或者通过标准预定一个门限值,当基站配置的CSI-RS/TRS距离目标位置超过该门限值,L1信令/SI信令指示的CSI-RS/TRS availability其validate timer=0,或者此时终端不希望利用该CSI-RS/TRS资源用于目标资源对应的channel tracking操作。CSI-RS/TRS距离目标位置小于等于该门限值,UE假定该CSI-RS资源对应的validate timer大于0。所述目标位置可以是PEI信令的发送资源,也可以是paging DCI/paging PDSCH或者多媒体广播组播业务等在空闲态发送业务对应的发送资源。
L1信令指示的CSI-RS/TRS availability时对应的validate timer的个数是指示信令发送类型的函数,或者与指示信令类型相关联。
PEI信令/SI指示的CSI-RS/TRS availability时对应的validate timer具有唯一的validate timer值;当paging DCI指示的CSI-RS/TRS availability时对应的validate timer具有至少一个timer值。
例如,基站通过SIB-X为终端配置至少一个validate timer值,基站通过paging DCI指示实际采用的validate timer值。
该示例四的有益效果:目前的相关技术都没有考虑到TRS位置,因为连接态TRS发送的位置取决于连接态的UE,未必能够与PO位置对齐或者具有确定的关系,本公开给出了一种基站把连接态终端的TRS共享给idle/inactive终端时的信令validate timer解决方案,通过确定恰当的timer值,能够缓解L1信令发生漏检时基站与终端理解模糊导致的功耗浪费;恰当配置的validate timer值利于基站侧信令开销降低,与可能的终端接收功耗的节省。
综上,网络侧设备为空闲态终端和/或非激活态终端配置参考信号对应的传输资源,并通过物理层信令和/或高层信令指示参考信号可获得性,从而使 得空闲态或非激活态的终端能够准确获取该第一传输资源上是否存在参考信号,利于不同场景下基站开销降低以及基站与终端功耗的节省;能够有效避免空闲态终端和/或非激活态终端进行参考信号盲检操作,进而降低了终端的功耗。
