在5G新空口(New Radio,NR)系统中,由于5G支持更大的带宽、更高的吞吐,和更复杂的业务及其与其相匹配的更复杂的处理技术,终端的省电设计变得十分必要。省电的优化设计能节省终端的功耗,延长电池的寿命,从而提高用户的体验。

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、完整地描述,显然,所描述的实施例仅仅是本申请一部分实施例,并不是全部的实施例。基于本申请中的实施例,本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例,都属于本申请保护的范围。
在进行本公开实施例的说明时,首先对下面描述中所用到的一些概念进 行解释说明。
寻呼(paging)消息:
寻呼消息包括两部分,即寻呼PDCCH与寻呼物理下行共享信道(Physical Downlink Shared Channel,PDSCH)。基于终端节电的考虑,在新空口(New Radio,NR)对RRC空闲(IDLE)和RRC非激活(INACTIVE)状态中的用户设备(User equipment,UE)paging接收需要遵循非连续接收(Discontinuous Reception,DRX)原则。
网络侧可以通过高层信令(RRC信令和/或核心网信令)为UE配置寻呼周期即DRX周期,系统信息还会广播一个默认的DRX周期,UE根据高层信令配置DRX与默认DRX周期的最小值确定最终用于接收寻呼的DRX周期。终端在每个DRX周期监听一个PO。
一个PO由一组PDCCH监听机会(Monitoring Occasion,MO)组成,可以包含多个时隙,例如子帧或正交频分复用(Orthogonal frequency division multiplex,OFDM)符号。寻呼下行控制信息(Downlink Control Information,DCI)在PDCCH MO上发送。
一个寻呼帧(Paging Frame,PF)是一个无线帧,可以包含一个或多个PO或PO的起始点。在多波束(multi-beam)操作中,UE假定所有的传输波束都重复传输相同的寻呼消息与短消息。选择恰当的波束并接收寻呼与短消息由UE实现。
寻呼帧对应的系统帧号(System Frame number,SFN)可以根据如下公式确定:
(SFN+PF_offset)mod T=(T div N)*(UE_ID mod N)
其中,T表示DRX周期,其单位是无线帧;N表示每个DRX周期内PF的总数,PF_offset表示用于确定寻呼帧的偏置,UE_ID=5G-S-TMSI mod 1024,其中5G-S-TMSI是48比特的比特串。
每个寻呼帧内包含Ns个寻呼机会,每个PO的索引为i_s,根据如下公式确定:
i_s=floor(UE_ID/N)mod Ns
其中,参数N、PF_offset、Ns,由系统信息块(System Information Block, SIB1)信令通知。
UE根据寻呼搜索空间和“DownlinkConfigCommonSIB”字域配置的第一寻呼PDCCH监听机会“firstPDCCH-MonitoringOccasionOfPO”和一个SSB对应的paging PDCCH MO个数“nrofPDCCHMonitoringOccasionPerSSB-InPO”来确定寻呼的PDCCH监听机会。当寻呼搜索空间(paging Search Space)配置“SearchSpaceId=0”时,寻呼PDCCH监听机会与剩余最小系统信息(Remaining Minimum SI,RMSI)相同。
当为寻呼搜索空间配置“SearchSpaceId=0”时,Ns为1或2。对于Ns=1,PF中只有一个PO,其起始点即第一PDCCH监听机会的起点。对于Ns=2,PO在PF的前半帧(i_s=0)或后半帧(i_s=1)。
当寻呼搜索空间配置配置的“SearchSpaceId”不等于0时,UE监听第(i_s+1)个PO。PO是一组“S*X”个连续的PDCCH监听机会,其中S是根据SIB1承载的同步信号块(Synchronization Signal and PBCH block,SSB)位置信息确定实际传输的SSB的数目,X表示“nrofPDCCHMonitoringOccasionPerSSB-InPO”配置的每个SSB对应的PDCCH MO个数,如果该值不配置则X等于1。而且PO中的第[x*S+K]个寻呼PDCCH监听机会对应于第K个发送的SSB,其中x=0,1,…,X-1,K=1,2,…,S。寻呼配置的PDCCH监听机会不与上行链路(Uplink,UL)符号重叠,且自PF中的第一个寻呼MO开始从0依次编号。当配置了“firstPDCCH-MonitoringOccasionOfPO”时,第(i_s+1)个PO的PDCCHMO的起始点为高层参数“firstPDCCH-MonitoringOccasionOfPO”的第(i_s+1)个值,否则,第(i_s+1)个PO的PDCCH MO的起始点等于i_s*S*X。
具体地,本公开的实施例提供了一种寻呼提前指示的传输方法、装置及设备,用以确定PEI的资源位置进而实现PEI的传输
如图1所示,本公开的实施例提供了一种寻呼提前指示的传输方法方法,具体包括以下步骤:
步骤11:用户设备根据目标(Target)同步信号块SSB、目标寻呼机会PO以及目标寻呼帧PF中的至少一项,或者根据第一帧号,确定寻呼提前指 示PEI的资源位置。
其中,所述目标SSB为多个SSB中的1个SSB;所述目标PO为多个PO中的1个PO;所述目标PF为多个PF中的一个PF。在确定所述PEI的资源位置时,可以根据目标SSB、目标PO、目标PF中的一个或者多个的组合确定,例如:根据目标SSB确定PEI的资源位置、根据目标PO确定PEI的资源位置、根据目标PF确定PEI的资源位置、根据目标SSB和目标PO确定PEI的资源位置、根据目标SSB和目标PF确定PEI的资源位置等,在此不做列举。其中,根据目标SSB和目标PO确定PEI的资源位置可以为:根据目标PO确定目标SSB,根据目标SSB确定PEI的资源位置;根据目标SSB和目标PF确定PEI的资源位置可以为:根据目标PF确定目标SSB,根据目标SSB确定PEI的资源位置。
可选地,所述第一帧号为所述PEI所在的无线帧的帧号,实施例中,所述用户设备可以根据所述第一帧号确定所述PEI的资源位置。其中,所述第一帧号对应的无线帧可以包括一个或者多个PEI,或者一个或者多个PEI的起始位置。
步骤12:用户设备在所述资源位置接收或者检测网络侧设备发送的PEI;其中,所述PEI用于指示寻呼的存在情况。
UE确定PEI的资源位置后,在所述资源位置接收或者检测PEI,所述PEI可以用于指示寻呼的存在情况,即指示是否存在寻呼,例如:“1”表示存在寻呼,“0”表示不存在寻呼。UE可以根据PEI确定是否需要进行寻呼消息的接收,在不需要接收寻呼消息时,可以进入低功耗或休眠状态,从而降低UE功耗。
本申请的实施例,用户设备根据目标SSB、目标PO、目标PF中的一个或者多个确定PEI的资源位置,或者根据第一帧号确定所述PEI的资源位置,从而在所述资源位置接收或者检测用于指示寻呼存在情况的PEI,能够降低UE的功耗。其中,通过SSB确定PEI的资源位置,可以使PEI距离SSB更近,此时可以获得更大的节电效果。空闲态的UE可以在接收完SSB后立刻接收PEI,当PEI指示该UE没有寻呼时,UE可以尽快进入低功耗睡眠状态,从而降低功耗,本申请实施例还提供了当一个PEI对应多个PO或者多个PF 时确定PEI资源位置的方法。
可选地,所述方法还包括:确定所述目标SSB、所述目标PO以及所述目标PF中的至少一项。
下面分别说明确定目标SSB、确定目标PO以及确定目标PF的实现方法。值得指出的是,在确定上述三者中的多个(例如目标SSB和目标PO)时,与分别确定的步骤相同。
作为一个可选实施例,确定所述目标SSB,包括:

具体地,所述根据所述目标参数,确定所述目标SSB,可以包括:

该实施例中,可以根据目标PO或者目标PF的位置,以及所述目标PO或者目标PF与所述目标SSB的距离,确定所述目标SSB。以目标PO为例,所述距离满足:
Y*Period_SSB<PO_location–SSB_location≤(Y+1)*Period_SSB
Period_SSB表示SSB的周期,PO_location表示目标PO的位置(如:目标PO的第一个MO的起始位置所在帧号、子帧号、时隙号或者OFDM符号),SSB_location表示目标SSB的位置(例如:目标SSB的开始位置或者结束位置所在的帧号、子帧号、时隙号或者OFDM符号)。PO_location–SSB_location表述所述距离。优选地,Y1=1,在Y1大于1时,所述距离为满足上述条件的最大距离或者最小距离,此时,所述目标SSB为满足最大距离或者最小距离条件对应的SSB。Y是和所述目标SSB与所述目标参数间隔的SSB数量相关的函数。

(3)根据PEI的周期确定所述目标PO或者目标PF。
(4)在一个PEI对应一个PO的情况下,所述目标PO为用户设备需要监听的PO,所述目标PF为用户设备需要监听的PO对应的PF。
在该实施例中,确定目标PO或者确定目标PF,可以直接根据所述目标PO或者目标PF确定PEI的资源位置;或者,根据目标PO或者目标PF确定目标SSB,根据目标SSB确定PEI的资源位置。
可选地,根据目标SSB、目标PO以及目标PF中的至少一项,确定PEI 的资源位置,包括:
根据所述目标SSB、或者所述目标PO、或者所述目标PF的资源位置,以及第一偏移,确定所述PEI的资源位置;其中,所述第一偏移为所述目标SSB、或者所述目标PO、或者所述目标PF的资源位置与PEI的资源位置的偏移。
其中,所述第一偏移可以为网络侧配置,也可以为协议约定,即固定PEI和目标SSB的间隔、或者PEI和目标PO的间隔、或者PEI和目标PF的间隔。以所述目标SSB为例,所述第一偏移的确定方式可以包括:
一:配置的PEI与目标SSB的偏移:PEI_location=SSB_location+Offset;其中,PEI_location为PEI的开始位置或者结束位置所在的帧号、子帧号、时隙号或者OFDM符号;SSB_location为目标SSB的开始位置所在的帧号、子帧号、时隙号或者OFDM符号。
需要说明的是,所述第一偏移小于所述目标SSB的周期长度;或者,所述第一偏移与所述目标SSB的周期成正比。

该实施例中,根据目标SSB、目标PO、目标PF中的一项或者多项可以确定PEI的开始位置、结束位置、监听起始位置、监听结束位置等。其中,可以首先确定PEI的开始位置或者监听起始位置,根据所述开始位置或者监听起始位置可以确定PEI的结束位置或者监听结束位置。
作为一个可选实施例,在所述PEI的资源位置包括所述PEI的开始位置和/或所述PEI的监听起始位置的情况下,根据所述PEI的开始位置和/或所述PEI的监听起始位置,以及所述PEI的持续时间(duration),确定所述PEI的结束位置和/或所述PEI的监听结束位置。
所述PEI的持续时间可以为网络侧配置的或者协议规定的固定的时间值。根据PEI的开始位置以及duration可以确定PEI的结束位置;根据PEI的监听起始位置和duration可以确定PEI的监听结束位置。
需要说明的是,若首先确定PEI的结束位置或者监听结束位置,根据所述持续时间也可以确定出PEI的开始位置或者监听起始位置。
在本申请的实施例中,根据目标SSB、目标PO、目标PF中的一项或者多项确定出PEI的资源位置后,还可以对确定的资源位置进行判断是否满足预定的条件,在满足条件时可以在该确定的资源位置进行PEI的接收或者检测。下面具体说明。
作为一个可选实施例,所述方法还包括:
确定所述资源位置是否满足第一条件;在不满足所述第一条件的情况下,更新所述资源位置为:所述资源位置与SSB的周期的差值。
可选地,所述第一条件包括:所述资源位置与目标PO或者目标PF的资源位置的距离,大于或者等于第一间隔。
所述第一间隔为PEI的资源位置(优选为结束位置或者监听结束位置)与目标PO或者目标PF的距离的最小值。所述目标PO或者目标PF的资源位置可以为目标PO的第一个MO的位置或者目标PO的起始位置,或者目标PO的结束位置。
该实施例中,在确定所述资源位置是否满足第一条件时,可以对资源位置中的结束位置或者监听结束位置进行判断。例如:所述结束位置满足条件:PO_location-PEI_end≥min_gap,min_gap即所述第一间隔,可以是网络侧配置的,也可以是UE上报的。
在所述PEI的资源位置满足所述第一条件时,则可以执行步骤12中在所述资源位置接收或者检测网络侧设备发送的PEI的步骤。在所述PEI的资源位置不满足第一条件时,需要更新的所述资源位置为:所述资源位置(即步骤11中确定的资源位置)与SSB的周期的差值,即:资源位置更新为PEI_location-Period_SSB。即,当网络侧设备根据系统消息或者广播信令配置或者协议约定了Y后,UE根据min_gap计算并更新Y,且更新Y为Y+1。
作为一个可选实施例,所述PEI包括X个波束,所述PEI的资源位置包 括:X个波束的PEI对应的X个资源位置;

以所述第一信号为SSB、TRS信号为例,多个资源位置中的第K个资源位置和SSB、TRS等信号所在的资源位置发生全部或者部分重叠时,该第K个资源位置为无效的PEI资源位置,第K+1个资源位置用于传输第K个波束的PEI,即:可以丢弃或者跳过无效的PEI资源位置,有效的PEI资源位置顺延。
作为一个可选实施例,对于所述根据第一帧号确定PEI的资源位置的方式,所述方法还包括:
确定所述第一帧号,所述第一帧号为所述PEI所在的无线帧的帧号。用户设备确定所述第一帧号,即确定PEI所在的无线帧的帧号,所述第一帧号可以用PEI_SFN表示。
可选地,所述方法还包括:确定第一索引,所述第一索引为所述PEI的索引;

该实施例中,所述第一索引为PEI的索引,可以为PEI在该PEI所在的无线帧包括的至少一个PEI中的索引。所述第一索引可以通过PEI_i_s表示,例如:当第一帧号对应的无线帧中包括1个PEI时,则PEI_i_s=0;当第一帧号对应的无线帧中包括2个PEI时,则PEI_i_s=0或1。
在本申请的实施例中,所述用户设备根据第一帧号确定PEI的资源位置 可以包括:仅根据第一帧号确定所述PEI的资源位置;或者,根据所述第一帧号和第一索引确定所述PEI的资源位置。例如:在所述第一帧号对应的无线帧中仅包括一个PEI时,可以仅根据所述第一帧号确定所述PEI的资源位置;在所述第一帧号对应的无线帧包括多个PEI时,可以利用所述第一帧号所述第一索引共同确定所述PEI的资源位置。
可选地,所述确定第一帧号,包括:根据第三参数,确定所述第一帧号,所述第三参数包括:第二间隔(PEI_offset)、寻呼帧的偏置(PF_offset)、DRX周期(T)、每个DRX周期内PF的总数量(N)、每个PF内包含的PO数量(Ns)、一个PEI对应的PO数量(X)以及用户设备标识(UE_ID)中的至少一项。
其中,所述第二间隔为用于确定所述第一帧号的间隔,所述第二间隔可以用于描述所述第一帧号与PO所在帧号(即PF)的间隔的无线帧的数目。所述寻呼帧的偏置用于确定PF的offset。根据所述第三参数中的一项或者多项可以确定所述第一帧号。
可选地,所述第一帧号与第四参数、第五参数以及第六参数的乘积相关。其中:所述第四参数,与所述DRX周期和所述每个DRX周期内PF的总数量中的至少一项相关。可选地,若所述第四参数与所述DRX周期(T)和所述每个DRX周期内PF的总数量(N)相关,则所述第四参数可以满足(T div N)。
所述第五参数,与所述用户设备标识、所述每个DRX周期内PF的总数量以及所述第六参数中的至少一项相关。
所述第六参数,与一个PEI对应的PO数量以及每个PF内包含的PO数量中的至少一项相关。
可选地,若所述第六参数与一个PEI对应的PO数量(X)以及每个PF内包含的PO数量(Ns)相关,则所述第六参数(A)可以满足:A=max(X/Ns,1),即取X/Ns与1中的最大值;或者,所述第六参数(A)可以满足:A=max(floor(X/Ns),1),即取floor(X/Ns)与1中的最大值,floor表示向下取整。
若所述第五参数与所述用户设备标识(UE_ID)、所述每个DRX周期内 PF的总数量(N)以及所述第六参数(A)有关,则所述第五参数可以满足:floor((UE_ID mod N)/A)。
具体地,所述第一帧号、所述第二间隔以及所述寻呼帧的偏置之和,与所述DRX周期的取模运算结果,等于所述第四参数、所述第五参数以及所述第六参数的乘积。
以所述第四参数满足(T div N),所述第五参数满足floor((UE_ID mod N)/A),所述第六参数满足A=max(X/Ns,1)或A=max(floor(X/Ns),1)为例,则所述第一帧号满足如下公式:
(PEI_SFN+PF_offset+PEI_offset)mod T
=(T div N)*floor((UE_ID mod N)/A)*A
其中,PEI_SFN为PEI所在的无线帧的帧号(即所述第一帧号);PF_offset为用于确定PF的offset;PEI_offset为用于确定PEI_SFN的offset;T为DRX周期;N为每个DRX周期内PF的总数量;Ns为每个PF内包含的PO数量;X为1个PEI对应的PO的数量;UE_ID为5G-S-TMSI mod 1024。
需要说明的是,PF_offset、T、N、Ns可以为网络侧设备配置的寻呼参数。PEI_SFN可以为网络侧设备配置的,也可以为协议约定,本实施例对此不做限定。PEI_offset用于描述PEI所在帧号(PEI_SFN)与PO所在的帧号(PF)的间隔的无线帧,其单位为无线帧。X可以是网络侧设备配置的,也可以为协议约定的,本实施例对此不做限定。
作为一个可选实施例,所述确定第一索引,可以包括:
方式(a):根据第七参数,确定所述第一索引,所述第七参数包括:用户设备标识(UE_ID)、每个DRX周期内PF的总数量(N)、每个PF内包含的PO数量(Ns)以及一个PEI对应的PO数量(X)中的至少一项;
或者
方式(b):根据PO的索引(i_s)、每个PF内包含的PO数量(Ns)以及一个PEI对应的PO数量(X),确定所述第一索引。所述PO的索引可以为所述用户设备接收或者检测的PO的索引。
该实施例中,用户设备确定第一索引,即PEI在第一帧号中的索引,或者,为PEI在PEI所在的无线帧包括的至少1个PEI中的索引,所述第一索 引可以用PEI_i_s表示。对于上述方式(a),若所述第七参数包括:用户设备标识(UE_ID)、每个DRX周期内PF的总数量(N)、每个PF内包含的PO数量(Ns)以及一个PEI对应的PO数量(X),则所述第一索引可以满足:
PEI_i_s=(floor(UE_ID/N)mod Ns)mod B
其中,PEI_i_s为所述第一索引,也可以表示为PEI在所述第一帧号对应的无线帧包含的一个或者多个PEI的索引;N为每个DRX周期内PF的总数量;Ns为每个PF内包含的PO数量;X为1个PEI对应的PO的数量;B=max(Ns/X,1)或者B=max(floor(Ns/X),1);UE_ID为5G-S-TMSI mod 1024。
其中,T、N、Ns可以为网络侧设备配置的寻呼参数。X可以为网络侧设备配置的,也可以为协议约定,本实施例对此不做限定。
对于所述方式(b),即所述第一索引可以根据PO的索引(i_s)、每个PF内包含的PO数量(Ns)以及一个PEI对应的PO数量(X)确定,则所述第一索引可以满足:
PEI_i_s=i_s mod B
其中,PEI_i_s为所述第一索引,i_s为用户设备确定的PO对应的i_s;X为1个PEI对应的PO的数量。Ns为每个PF内包含的PO数量,B=max(Ns/X,1)或者B=max(floor(Ns/X),1)。
该实施例中,用户设备在确定PEI的资源位置时,可以根据第一帧号确定,其中,可以仅根据所述第一帧号确定,也可以根据所述第一帧号和第一索引确定,对于用户设备,该确定方式简单,对于协议影响较少。
需要说明的是,网络侧设备也可以根据目标SSB、目标PO以及目标PF中的至少一项,或者根据第一帧号,确定PEI的资源位置,从而在确定的资源位置发送PEI,使UE在确定的资源位置接收或者检测PEI。UE确定PEI的资源位置的方法同样适用于网络侧设备,在此不做赘述。
下面通过具体实施例说明本申请的寻呼提前指示的传输方法的流程。
实施例一:以通过目标SSB确定寻呼提前指示PEI的资源位置,通过目标PO确定目标SSB为例。该实施例中,根据目标SSB确定PEI的开始位置或结束位置。
步骤一:确定目标PO,根据目标PO确定目标SSB。
下面分两个方案进行说明:方案一为PO密集场景;方案二为PO稀疏场景。
方案一:Ns=4,N=T(PO密集场景)。
(1)确定目标(Target)PO,UE确定网络侧设备多个PO中的Target PO,可以包括如下几种方式:
方式1:UE根据寻呼参数N和Ns确定Target PO;
N表示一个DRX周期内的寻呼帧的个数,Ns表示一个寻呼帧中PO的个数,因此,当N和Ns取值比较大时,表示该DRX周期中PO密集。
一种可能的实现方式:Target PO为X个PO中的1个PO,X的取值和寻呼参数N和Ns有关。例如,当Ns和N取值比较大时,X取值大,当N和Ns取值比较小时,X取值小。
UE确定网络侧设备的每个PO对应的参数0,如:参数0=PO_Index mod X,这里,PO_Index=SFN_PF*N*Ns/T+i_s,PO_Index表示PO在DRX周期中的索引。所述参数0可以为PO在X个PO中的索引。
可选地,所述PO_Index还可以表示为:
PO_Index=floor(SFN_PF*N*Ns/T)+i_s
即所述参数0表示为:参数0=(floor(SFN_PF*N*Ns/T)+i_s)mod X。
其中:SFN_PF为PO对应的PF所在的SFN;N为一个DRX周期中PF的个数;Ns为一个PF中PO的个数,T为DRX周期的长度,i_s为PO在对应的PF中的索引。
可以约定,参数0取值为0时对应的PO为Target PO。
需要说明的是,该实施例不限定于参数0取值为0对应的PO为目标PO,协议可以预定义目标参数为0、…、X-1中的任意的一个取值对应的PO为目标PO,通过预定义的方法,网络侧设备和UE不会对目标PO对应的参数0产生歧义。还可以通过系统消息广播通知参数0为0、…、X-1中的任意的一个取值对应的PO为目标PO,对此不做限定。
方式2:UE根据网络侧设备广播的1个PEI对应X个PO的参数X确定Target PO;
该方式2与上述方式1的不同之处为:X的取值为网络侧设备通过系统消息或者其他广播信令通知的,网络侧设备和UE通过广播的1个PEI对应X个PO的参数X确定Target PO。
方式3:UE根据PEI的周期确定Target PO;
网络侧设备通过系统消息或者其他广播信令配置PEI的周期,例如,协议约定Target PO为每个PEI周期内第一个PF对应的第一个PO。
如图2所示,Target PO为网络侧设备中每8个PO中的1个PO,因此,在该实施例中,X取值为8;图2中SSB周期为20ms。X的确定方法可以为上述三个方式中的任一方法。
可选地,也可以确定Target PF,该实施例优选确定目标PO。所述确定Target PF,例如,UE根据寻呼参数N和UE_ID中的至少一项确定目标PF;UE根据参数X确定目标PF,所述参数X用于指示1个PEI对应X个PO。需要说明的是,UE可以根据PEI的周期确定目标PF。下面通过具体实施例说明确定目标PF的方式,包括:
方式4:UE根据寻呼参数N确定目标PF;
一种可能的实现方式:Target PF为X1个PF中的1个PF,X1的取值和寻呼参数N有关。例如,当N取值比较大时,X1取值大,当N取值比较小时,X1取值小。
UE确定网络侧设备的每个PF对应的参数1,如:参数1=PF_Index mod X1,这里,PF_Index=SFN_PF_1*N/T,PF_Index表示PF在DRX周期中的索引。所述参数1可以为PF在X1个PF中的索引。
可选地,所述PF_Index还可以表示为:
PF_Index=floor(SFN_PF_1*N/T)
即所述参数1表示为:参数1=(floor(SFN_PF_1*N/T))mod X1。
其中:SFN_PF_1表示PF所在的SFN;N为一个DRX周期中PF的个数;T为DRX周期的长度。
可以约定,参数1取值为0时对应的PF为Target PF。
需要说明的是,该实施例不限定于参数1取值为0对应的PF为目标PF,协议可以预定义参数1为0、…、X1-1中的任意的一个取值对应的PF为目标PF,通过预定义的方法,网络侧设备和UE不会对目标PF对应的参数1产生歧义。还可以通过系统消息广播通知参数1为0、…、X1-1中的任意的一个取值对应的PF为目标PF,对此不做限定。
方式5:UE根据网络侧设备广播的1个PEI对应X个PO的参数X确定Target PF;
该方式5与上述方式4的不同之处为:该方式5中,X1的取值和X的取值有关,X的取值为网络侧设备通过系统消息或者其他广播信令通知的,网络侧设备和UE通过广播的1个PEI对应X个PO的参数X确定X1,比如,X1=X/Ns,通过X1和方式4确定目标PF。
方式6:UE根据PEI的周期确定Target PF;
网络侧设备通过系统消息或者其他广播信令配置PEI的周期,例如,协议约定Target PF为每个PEI周期内第一个PF。上述方式1-3为确定目标PO的可选实现方式,方式4-6为确定目标PF的可选实现方式。
其中,UE可以根据Target PO/Target PF确定Target SSB,该实施例以根据Target PO确定Target SSB为例。SSB中的MIB消息里带有帧号信息,UE在同步之后可以确定每个SSB所在的帧号、slot等。
目标SSB与目标PO的距离需要大于Y个SSB的周期且小于或等于(Y+Y1)个SSB的周期,具体可以是,目标SSB与目标PO间隔的帧数需要大于Y个SSB的周期对应的帧数且小于或等于(Y+1)个SSB的周期对应的帧数;或者,目标SSB与目标PO间隔的子帧数需要大于Y个SSB的周期对应的子帧数且小于或等于(Y+1)个SSB的周期对应的子帧数;或者,目标SSB与目标PO间隔的时隙数需要大于Y个SSB的周期对应的时隙数且小于或等于(Y+1)个SSB的周期对应的时隙数,或者,目标SSB与目标PO间隔的OFDM符号数需要大于Y个SSB的周期对应的OFDM符号数且小于或等于(Y+1)个SSB的周期对应的OFDM符号数。即,所述目标SSB满足:
Y*Period_SSB<PO_location–SSB_location≤(Y+1)*Period_SSB
其中,PO_location为目标PO的位置(例如:目标PO的第一个MO的 起始位置所在的帧号、子帧号、时隙号或者OFDM符号),SSB_location为目标SSB的位置(例如:目标SSB的开始位置或者结束位置所在的帧号、子帧号、时隙号或者OFDM符号)。PO_location–SSB_location表示目标SSB与目标PO的距离。该实施例中,Y1=1。
下面以目标SSB与目标PO间隔的帧数需要大于Y个SSB的周期对应的帧数且小于或等于(Y+1)个SSB的周期对应的帧数来举例说明,目标SSB所在的帧号(SFN_SSB)需要满足:
Y*Period_SSB<SFN_PO-SFN_SSB≤(Y+1)*Period_SSB
其中,SFN_PO为Target PO对应的PF所在的SFN,SFN_SSB为Target SSB所在的SFN。
通过以上公式,可以得到满足该公式的SSB为目标SSB。该公式中的Y可以通过如下方法确定:
1)系统消息或者广播信令SIB-X配置Y,Y为目标SSB和目标PO间隔的SSB的个数。
2)协议约定Y。
3)根据min_gap和/或Offset和/或SSB的波束数和/或PEI的波束数来计算确定Y。
方案二:Ns=1,N=T/4(PO稀疏场景)。
在方案二中与方案一不同的地方为:Target PO的确定方式。
确定Target PO,UE确定自己监听的PO为Target PO。
UE自己监听的PO对应的PF所在的帧号(SFN_PO)由PF和“first PDCCH-MonitoringOccasionOfPO”以及子载波间隔确定。当子载波间隔(Sub Carrier Space,SCS)为15kHz时,PO对应的PF所在的帧号为:
PF+floor(firstPDCCH-MonitoringOccasionOfPO/140)。
如图3所示,Target PO为UE确定自己监听的PO为Target PO,UE也可以确定自己监听的PO所在的PF为Target PF,图3中SSB的周期为20ms。该实施例以确定目标PO为例。
UE可以根据Target PO/Target PF确定Target SSB,该实施例以根据Target PO确定Target SSB为例。该部分方案和方案一相同,在此不做赘述。
以上步骤一为确定目标SSB,下面说明根据目标SSB确定PEI的资源位置。
步骤二:终端根据目标SSB确定PEI的资源位置。
可选地,根据Target SSB的位置确定PEI的开始位置或结束位置。
其中,可以配置PEI(即PEI的开始位置或结束位置)和目标SSB的Offset,PEI的开始位置或结束位置通过目标SSB的位置和Offset来确定,例如:满足以下公式:PEI_location=SSB_location+Offset,其中,PEI_location为PEI的开始位置或者结束位置所在的帧号、子帧号、时隙号或者OFDM符号。SSB_location为目标SSB的开始位置所在的帧号、子帧号、时隙号或者OFDM符号。
优选的,该Offset的长度小于SSB的周期长度,该Offset大于或等于0,此时PEI位于SSB的后面,如图2和图3所示。该Offset的长度小于SSB的周期长度可保证:
Y*Period_SSB<SFN_PO-SFN_PEI≤(Y+1)*Period_SSB
可选地,该Offset也可以为负数,即PEI位于SSB的前面。
Offset的取值也可以和SSB的周期有关,当SSB的周期越大时,Offset的可能取值越多或者越大,当SSB的周期越小时,Offset的可能取值越少或越小。即,Offset的可能候选值和SSB的周期成正比。
PEI(即PEI的开始位置或结束位置)和目标SSB的间隔Offset也可以为固定的,即间隔Offset可以是协议约定的。比如PEI位于目标SSB所在帧的下个帧的第一个slot,或者PEI位于目标SSB的所在slot的下一个slot。
可选地,可以配置或固定PEI的duration,根据PEI的开始位置(或结束位置)和PEI的duration确定PEI的结束位置(或开始位置)。
PEI的结束位置和PO的距离需要大于或者等于min_gap,比如需要满足如下条件:PO_location-PEI_end≥min_gap,该min_gap可以是网络侧配置的,也可以是UE上报的。或者,PEI的开始位置和PO的距离需要大于或者等于min_gap。
如果PEI的开始位置或者PEI的结束位置不满足上述条件,可以更新PEI开始位置或者结束位置为PEI_location-Period_SSB。即,当网络侧设备根据 系统消息或者广播信令配置或者协议约定了Y后,UE根据min_gap计算PEI的开始位置或者结束位置是否满足条件来确定是否更新Y,当需更新Y时,则更新Y为Y+1。更新的PEI的资源位置满足:
(Y+1)*Period_SSB<SFN_PO-SFN_PEI≤(Y+2)*Period_SSB
步骤三:所述终端在所述资源位置上接收或检测PEI。
在NR中,很多信号通过不同波束来发送。PEI很可能和寻呼DCI一样,PEI也有多个PEI机会,第K个PEI机会对应第K个SSB,此时,第K个PEI机会发送的PEI的波束对应于第K个SSB位置上SSB的波束,即,PEI机会的数目和SIB1承载的实际传输的SSB的数目相同。当PEI为多波束的PEI时,该实施例一确定PEI的资源位置的方案包括确定多波束(beam)的PEI对应的多个资源位置,比如上述PEI的开始位置为第1个波束的PEI所在的开始位置,PEI的结束位置为最后一个波束的PEI所在的结束位置。上述PEI的持续时间(duration)包括多个波束的PEI对应的资源位置,具体的如何确定PEI的duration中多个波束的PEI对应的资源位置,本申请实施例不做限定。假设PEI的duration中的第1个PEI资源位置开始编号,PEI的duration中包括多个PEI资源位置,当多个PEI资源位置中的第K个资源位置和SSB、TRS等信号所在的资源位置发生全部或者部分重叠时,该第K个资源位置为无效的PEI资源位置,第K+1个PEI资源位置用于传输第K个beam的PEI。即,丢弃(drop)或者跳过(skip)无效的PEI资源位置,此时原本在无效PEI资源位置上传输的PEI顺延到下一个有效的PEI资源位置上传输。
其中,在步骤三中,网络侧设备在所述资源位置发送PEI信号,对应的UE侧的步骤三的行为为UE在所述资源位置接收TRS/PEI信号。需要说明的是:网络侧设备是否在所述发送位置一定会发送PEI信号,取决于PEI信号的具体功能。举例说明,如果所述PEI用于指示PO处存在paging DCI,那么网络侧设备只会在PO处存在paging DCI的情况下在所述资源位置发送PEI,此时,UE会在确定的PEI的资源位置接收或检测PEI,最后UE接收到PEI。当PO处不存在paging DCI时,网络侧设备会在确定的所述资源位置不发送PEI。此时,UE会在确定的PEI的资源位置接收或检测PEI,最后UE无法接 收到PEI。
需要说明的是,本公开中所述的PEI可以是基于DCI的PEI(DCI-based PEI)或者是基于序列的PEI(sequence-based PEI),sequence-based PEI可以为基于TRS的PEI(TRS-based PEI)或者基于CSI-RS的PEI(CSI-RS-based PEI)或者基于辅同步信号(Secondary Synchronisation Signal,SSS)的PEI(SSS-based PEI),本申请实施例不对PEI的具体形式或者具体类型或者具体格式做限定。
本申请实施例中,所述PEI可以用来指示以下至少一项:
PO处Paging DCI是否存在;
PO处是否监测paging DCI;
PO处是否监测paging消息;
本寻呼周期内是否需要醒来监测paging消息;
PO处paging消息存在;
PO处监测paging DCI;
监测paging消息;
本寻呼周期内需要醒来监测paging消息;
TRS的可用性;
地震和海啸预警系统(Earthquake and Tsunami Warning System,ETWS)是否发送通知信息;
系统消息更新指示是否发送;
跟踪参考信号的波束的指示信息。
网络侧设备实现所述寻呼提前指示的传输方法的步骤与用户设备对应,在此不做赘述。
实施例二:以通过目标SSB确定PEI的资源位置,通过目标PO确定目标SSB为例。该实施例中,根据目标SSB确定PEI的监听起始位置。
步骤一:确定目标PO,根据目标PO确定目标SSB。
该实施例二的所述步骤一与实施例一的步骤一的实现方式相同,在此不做赘述。
步骤二:终端根据目标SSB确定PEI的资源位置。
可选地,可以根据Target SSB的位置确定PEI的监听起始位置。
其中,可以配置PEI的监听起始位置和目标SSB的Offset,PEI的监听起始位置通过目标SSB的位置和Offset来确定,例如,满足以下公式:PEI_location=SSB_location+Offset,PEI_location为PEI的起始监听位置所在的帧号、时隙号或者OFDM符号。SSB_location为目标SSB的开始位置所在的帧号、时隙号或者OFDM符号。
优选的,该Offset的长度小于SSB的周期长度,该Offset大于或等于0,此时PEI位于SSB的后面,如图4和图5所示,图4为PO密集场景,Ns=4,N=T,SSB的周期为20ms;图5为PO稀疏场景,Ns=1,N=T/4,SSB的周期为20ms。该Offset的长度小于SSB的周期长度可保证:
Y*Period_SSB<SFN_PO-SFN_PEI≤(Y+1)*Period_SSB
可选地,该Offset也可以为负数,即PEI的监听起始位置位于SSB的前面。
Offset的取值也可以和SSB的周期有关,当SSB的周期越大时,Offset的可能取值越多或者越大,当SSB的周期越小时,Offset的可能取值越少或越小。即,Offset的可能候选值和SSB的周期成正比。
其中,PEI的监听起始位置和目标SSB的间隔Offset也可以为固定的,即该间隔Offset可以是协议约定的。例如:PEI的监听起始位置位于目标SSB的下个帧的第一个slot,或者PEI位于目标SSB的所在slot的下一个slot。
可选地,可以配置PEI的搜索空间(Search space,SS)集,例如图4和图5所示的多搜索空间集(Multiple SS Set),UE从PEI的监听起始位置开始准备进行PEI的监听,PEI监听的具体起始位置由搜索空间集的“monitoringSlotPeriodicityAndOffset”进行指示。
具体地,PEI的监听结束位置可以通过PEI的监听起始位置(PEI_location)和duration来确定,比如,PEI_end=PEI_location+duration,此时,该duration是多个beam下多个搜索空间(search space)的持续时间。
PEI的监听结束位置(PEI_end)和PO的距离需要大于或者等于min_gap,比如需要满足如下条件:PO_location-(PEI_location+duration)≥min_gap,该min_gap可以是网络侧配置的,也可以是UE上报的。
如果PEI的监听结束位置不满足该条件,更新PEI的监听起始位置为PEI_location-Period_SSB。即,当网络设备根据系统消息或者广播信令配置或者协议约定了Y后,UE根据min_gap计算PEI的监听起始位置是否满足条件来确定是否更新Y,当需更新Y时,则更新Y为Y+1。新的PEI的监听起始位置满足:
(Y+1)*Period_SSB<SFN_PO-SFN_PEI≤(Y+2)*Period_SSB
步骤三:所述终端在所述资源位置上接收或检测PEI。
在NR中,很多信号通过不同beam来发送。PEI很可能和寻呼DCI一样,PEI也有多个PEI机会,第K个PEI机会对应第K个SSB,此时,第K个PEI机会发送的PEI的beam对应于第K个SSB位置上SSB的beam,即,PEI机会的数目和SIB1承载的实际传输的SSB的数目相同。当PEI为多beam的PEI时,该实施例二确定PEI资源位置的方案包括确定多beam的PEI对应的多个资源位置,比如所述PEI的监听起始位置为第1个beam的PEI的监听起始位置。所述PEI的duration包括多个beam的PEI对应的资源位置,具体的如何确定PEI的duration中多个beam的PEI对应的资源位置,本申请实施例不做限定。假设PEI的duration中的第1个PEI资源位置开始编号,PEI的duration中包括多个PEI资源位置,当多个PEI资源位置中的第K个资源位置和SSB、TRS等信号所在的资源位置发生全部或者部分重叠时,该第K个资源位置为无效的PEI资源位置,第K+1个PEI资源位置用于传输第K个beam的PEI。即,drop或者skip无效的PEI资源位置,此时,原本在无效PEI资源位置上传输的PEI顺延到下一个有效的PEI资源位置上传输。
网络侧设备实现所述寻呼提前指示的传输方法的步骤与用户设备对应,在此不做赘述。
实施例三:以通过目标PO确定PEI的资源位置为例。该实施例中,根据目标PO确定PEI的开始位置或结束位置。
步骤一:确定目标PO。
下面分两个方案进行说明:方案一为PO密集场景;方案二为PO稀疏场景。
方案一:Ns=4,N=T(PO密集场景)。如图6所示。
确定Target PO,UE确定网络侧设备的多个PO中的Target PO。包括如下几种方式:
方式1:UE根据寻呼参数N和Ns确定Target PO;
N表示一个DRX cycle中的寻呼帧的个数,Ns表示一个寻呼帧中PO的个数,因此,当N和Ns取值比较大时,表示该DRX cycle中PO密集。
一种可能的实现方式:Target PO为X个PO中的1个PO,X的取值和寻呼参数N和Ns有关。例如,当Ns和N取值比较大时,X取值大,当N和Ns取值比较小时,X取值小。
UE确定网络侧设备的每个PO对应的参数0,如:参数0=PO_Index mod X,这里,PO_Index=SFN_PF*N*Ns/T+i_s,PO_Index表示PO在DRX周期中的索引。所述参数0可以为PO在X个PO中的索引。
可选地,所述PO_Index还可以表示为:
PO_Index=floor(SFN_PF*N*Ns/T)+i_s
即所述参数0表示为:参数0=(floor(SFN_PF*N*Ns/T)+i_s)mod X。
其中:SFN_PF为PO对应的PF所在的SFN;N为一个DRX周期中PF的个数;Ns为一个PF中PO的个数,T为DRX周期的长度,i_s为PO在对应的PF中的索引。
可以约定,参数0取值为0时对应的PO为Target PO。
需要说明的是,该实施例不限定于参数0取值为0对应的PO为目标PO,协议可以预定义目标参数为0、…、X-1中的任意的一个取值对应的PO为目标PO,通过预定义的方法,网络侧设备和终端不会对目标PO对应的参数0产生歧义。还可以通过系统消息广播通知参数0为0、…、X-1中的任意的一个取值对应的PO为目标PO,对此不做限定。
方式2:UE根据网络侧设备广播的1个PEI对应X个PO的参数X确定Target PO;
该方式2与上述方式1的不同之处为:X的取值为网络侧设备通过系统消息或者其他广播信令通知的,网络侧设备和UE通过广播的1个PEI对应X 个PO的参数X确定Target PO。
方式3:UE根据PEI的周期确定Target PO;
网络侧设备通过系统消息或者其他广播信令配置PEI的周期,例如:协议约定Target PO为每个PEI周期内第一个PF对应的第一个PO。
可选地,也可以确定Target PF,该实施例优选确定目标PO。所述确定Target PF例如:,UE根据寻呼参数N和UE_ID中的至少一项确定目标PF;UE根据参数X确定目标PF,所述参数X用于指示1个PEI对应X个PO。UE也可以根据PEI的周期确定目标PF。下面通过具体实施例说明确定目标PF的方式,包括:
方式4:UE根据寻呼参数N确定目标PF;
一种可能的实现方式:Target PF为X1个PF中的1个PF,X1的取值和寻呼参数N有关。例如,当N取值比较大时,X1取值大,当N取值比较小时,X1取值小。
UE确定网络侧设备的每个PF对应的参数1,如:参数1=PF_Index mod X1,这里,PF_Index=SFN_PF_1*N/T,PF_Index表示PF在DRX周期中的索引。所述参数1可以为PF在X1个PF中的索引。
可选地,所述PF_Index还可以表示为:
PF_Index=floor(SFN_PF_1*N/T)
即所述参数1表示为:参数1=(floor(SFN_PF_1*N/T))mod X1。
其中:SFN_PF_1表示PF所在的SFN;N为一个DRX周期中PF的个数;T为DRX周期的长度。
可以约定,参数1取值为0时对应的PF为Target PF。
需要说明的是,该实施例不限定于参数1取值为0对应的PF为目标PF,协议可以预定义参数1为0、…、X1-1中的任意的一个取值对应的PF为目标PF,通过预定义的方法,网络侧设备和UE不会对目标PF对应的参数1产生歧义。还可以通过系统消息广播通知参数1为0、…、X1-1中的任意的一个取值对应的PF为目标PF,对此不做限定。
方式5:UE根据网络侧设备广播的1个PEI对应X个PO的参数X确定Target PF;
该方式5与上述方式4的不同之处为:该方式5中,X1的取值和X的取值有关,X的取值为网络侧设备通过系统消息或者其他广播信令通知的,网络侧设备和UE通过广播的1个PEI对应X个PO的参数X确定X1,比如,X1=X/Ns,通过X1和方式4确定目标PF。
方式6:UE根据PEI的周期确定Target PF;
网络侧设备通过系统消息或者其他广播信令配置PEI的周期,例如,协议约定Target PF为每个PEI周期内第一个PF。
上述方式1-3为确定目标PO的可选实现方式,方式4-6为确定目标PF的可选实现方式。
方案二:Ns=1,N=T/4(PO稀疏场景),如图7所示。
在方案二中与方案一不同的地方为:Target PO的确定方式。
确定Target PO,UE确定自己监听的PO为Target PO。
UE自己监听的PO对应的PF所在的帧号(SFN_PO)由PF和“first PDCCH-MonitoringOccasionOfPO”以及子载波间隔确定。当SCS为15kHz时,PO对应的PF所在的帧号为:
PF+floor(firstPDCCH-MonitoringOccasionOfPO/140)。
可选地,UE也可以确定自己监听的PO所在的PF为Target PF。该实施例优选确定目标PO。
步骤二:终端根据目标PO确定PEI的资源位置。
可选地,根据Target PO的位置确定PEI的开始位置或结束位置。
其中,可以配置PEI(PEI的开始位置或结束位置)和目标PO的Offset,PEI的开始位置或结束位置通过目标PO的位置和Offset来确定,例如:PEI的开始/结束位置所在的帧号(SFN_PEI)需要满足:
Y*Period_SSB<SFN_PO-SFN_PEI≤(Y+1)*Period_SSB
即:Y*Period_SSB<Offset≤(Y+1)*Period_SSB。其中,SFN_PO为Target PO对应的PF所在的SFN。
可选地,该Offset也可以为负数,即PEI位于SSB的前面。
Offset的取值也可以和SSB的周期有关,当SSB的周期越大时,Offset的可能取值越多或者越大,当SSB的周期越小时,Offset的可能取值越少或 越小。即,Offset的可能候选值和SSB的周期成正比。
PEI(即PEI的开始位置或结束位置)和目标SSB的间隔Offset也可以为固定的,即间隔Offset可以是协议约定的。比如PEI位于目标PO所在帧的前L个帧的第一个slot。
可选地,可以配置或固定PEI的duration,根据PEI的开始位置(或结束位置)和PEI的duration确定PEI的结束位置(或开始位置)。
PEI的结束位置和PO的距离需要大于或者等于min_gap,比如需要满足如下条件:PO_location-PEI_end≥min_gap,该min_gap可以是网络侧配置的,也可以是UE上报的。或者,PEI的开始位置和PO的距离需要大于或者等于min_gap。
如果PEI的开始位置或者PEI的结束位置不满足上述条件,可以更新PEI开始位置或者接收位置为:PEI_location-Period_SSB。
所述终端在所述PEI的开始位置处开始监听PEI。
步骤三:所述终端在所述资源位置上接收或检测PEI。
网络侧设备实现所述寻呼提前指示的传输方法的步骤与用户设备对应,在此不做赘述。
实施例四:以通过目标PO确定PEI的资源位置为例。该实施例中,根据目标PO确定PEI的监听起始位置。
步骤一:确定目标PO。
该实施例四的所述步骤一与实施例三的步骤一的实现方式相似,包括PO密集场景,Ns=4,N=T,如图8所示;PO稀疏场景,Ns=1,N=T/4,如图9所示。具体实现过程在此不做赘述。
步骤二:终端根据目标PO的位置确定PEI的资源位置。
可选地,可以根据Target PO的位置确定PEI的监听起始位置。
其中,可以配置PEI的监听起始位置和目标PO的Offset,PEI的监听起始位置通过目标PO的位置和Offset来确定,例如:PEI的监听起始位置所在的帧号(SFN_PEI)需要满足:
Y*Period_SSB<SFN_PO-SFN_PEI≤(Y+1)*Period_SSB
即,Y*Period_SSB<Offset≤(Y+1)*Period_SSB。其中,SFN_PO为 Target PO对应的PF所在的SFN。
可选地,该Offset也可以为负数,即PEI的监听起始位置位于SSB的前面。
Offset的取值也可以和SSB的周期有关,当SSB的周期越大时,Offset的可能取值越多或者越大,当SSB的周期越小时,Offset的可能取值越少或越小。即,Offset的可能候选值和SSB的周期成正比。
PEI的监听起始位置和目标PO的间隔Offset也可以为固定的,即间隔Offset可以是协议约定的。比如PEI的监听起始位置位于目标PO所在帧的前L个帧的第一个slot。
可选地,可以配置PEI的搜索空间集,UE从PEI的监听起始位置开始准备进行PEI的监听,PEI监听的具体起始位置由搜索空间集的“monitoringSlot PeriodicityAndOffset”进行指示。
其中,PEI的监听结束位置可以通过PEI的监听起始位置(PEI_location)和duration来确定,比如,PEI_end=PEI_location+duration,此时,该duration是多个beam下多个search space的持续时间。
PEI的监听结束位置(PEI_end)和PO的距离需要大于或者等于min_gap,比如需要满足如下条件:PO_location-(PEI_location+duration)≥min_gap,该min_gap可以是网络侧配置的,也可以是UE上报的。
如果PEI的监听结束位置不满足上述条件,可以更新PEI的监听起始位置为PEI_location-Period_SSB。
终端在所述PEI的监听起始位置处开始监听PEI。
步骤三:所述终端在所述资源位置上接收或检测PEI。
网络侧设备实现所述寻呼提前指示的传输方法的步骤与用户设备对应,在此不做赘述。
本申请的实施例中,用户设备根据目标SSB、目标PO、目标PF中的一个或者多个确定PEI的资源位置,从而在所述资源位置接收或者检测用于指示寻呼存在情况的PEI,能够降低UE的功耗。其中,通过SSB确定PEI的资源位置,可以使PEI距离SSB更近,此时可以获得更大的节电效果。空闲态的UE可以在接收完SSB后立刻接收PEI,当PEI指示该UE没有寻呼时, UE可以尽快进入低功耗睡眠状态,从而降低功耗,本申请实施例还提供了当一个PEI对应多个PO或者多个PF时确定PEI资源位置的方法。
实施例五:以根据第一帧号和第一索引确定所述PEI的资源位置为例。
UE和gNB确定第一帧号以及第一索引,所述第一帧号为PEI所在的无线帧号,所述第一索引为所述PEI在所述第一帧号对应的无线帧包括的一个或者多个PEI的索引。UE和gNB根据所述第一帧号以及第一索引确定所述PEI的资源位置。UE在所述资源位置接收或者检测gNB发送的PEI。
该第一帧号对应的无线帧包括1个或多个PEI,或者1个或多个PEI的起始位置。所述第一索引为PEI在该PEI所在的无线帧包括的至少1个PEI中的索引,用于指示所述PEI在第一帧号中的位置。
步骤1:UE确定第一帧号,即PEI所在的无线帧号,用PEI_SFN表示。所述PEI所在的无线帧号(即所述第一帧号)满足如下公式:
(PEI_SFN+PF_offset+PEI_offset)mod T
=(T div N)*floor((UE_ID mod N)/A)*A
其中,PEI_SFN为PEI所在的无线帧的帧号(即所述第一帧号);PF_offset为用于确定PF的offset;PEI_offset为用于确定PEI_SFN的offse;T为DRX周期;N为每个DRX周期内PF的总数量;Ns为每个PF内包含的PO数量;X为1个PEI对应的PO的数量;UE_ID为5G-S-TMSI mod 1024。A=max(X/Ns,1)即取X/Ns与1中的最大值;或者,A=max(floor(X/Ns),1),即取floor(X/Ns)与1中的最大值,floor表示向下取整。UE_ID为5G-S-TMSI mod 1024。
上述参数中,PF_offset、T、N、Ns可以为网络侧设备配置的寻呼参数。PEI_offset可以是网络侧设备配置的,或者,是协议约定的,在此不做限定。PEI_offset用于描述PEI所在帧号(PEI_SFN)与PO所在的帧号(PF)的间隔的无线帧,其单位为无线帧。X可以是网络侧设备配置的,或者,是协议约定的,在此不做限定。
步骤2:UE确定所述第一索引。所述第一索引即PEI在第一帧号中的索引,或者,为PEI在PEI所在的无线帧包括的至少1个PEI中的索引,用PEI_i_s表示。比如,当第一帧号对应的无线帧中包括1个PEI时,那么PEI_i_s=0; 当第一帧号对应的无线帧中包括2个PEI时,那么PEI_i_s=0或1。
确定所述第一索引可以包括如下两种方式:
方式1:PEI在第一帧号中的索引满足如下公式:
PEI_i_s=(floor(UE_ID/N)mod Ns)mod B
其中,PEI_i_s为所述第一索引,也可以表示为PEI在所述第一帧号对应的无线帧包含的一个或者多个PEI的索引;N为每个DRX周期内PF的总数量;Ns为每个PF内包含的PO数量;X为1个PEI对应的PO的数量;B=max(Ns/X,1)或者B=max(floor(Ns/X),1);UE_ID为5G-S-TMSI mod 1024。上述参数中,T、N、Ns可以为网络侧设备配置的寻呼参数。X可以是网络侧设备配置的,或者,是协议约定的,在此不做限定。
方式2,方式2中,所述第一索引满足如下公式:
PEI_i_s=i_s mod B
其中,PEI_i_s为所述第一索引,i_s为用户设备确定的PO对应的i_s;X为1个PEI对应的PO的数量。Ns为每个PF内包含的PO数量,B=max(Ns/X,1)或者B=max(floor(Ns/X),1)在该实施例五中,对于所述步骤1和所述步骤2,如图9b所示,以1个PEI对应2个PO,X=2举例说明。在图9b中,箭头指示的位置j表示第一索引PEI_i_s的位置,可以满足:
PEI_i_s=(floor(UE_ID/N)mod Ns)mod B
其中,B=max(Ns/X,1)或者B=max(floor(Ns/X),1)。
箭头指示的位置i表示所述第一帧号PEI_SFN对应的位置,所述第一帧号满足:
(PEI_SFN+PF_offset+PEI_offset)mod T
=(T div N)*floor((UE_ID mod N)/A)*A
其中,A=max(X/Ns,1)
UE通过如上步骤1确定的第一帧号可以确定PEI所在的SFN,再根据如上步骤2确定的第一索引确定PEI在该PEI所在的无线帧包括的至少1个PEI中的索引,该第一索引可以用于确定PEI在第一帧号中具体的资源位置。比如,第一帧号包括2个PEI,那么网络侧设备配置 “firstPDCCH-MonitoringOccasionOfPEI”中包括两个取值,PEI_i_s=0对应的PEI在第一帧号中的资源位置根据“firstPDCCH-MonitoringOccasionOfPEI”中的第一个数值确定,PEI_i_s=1对应的PEI在第一帧号中的资源位置根据“firstPDCCH-MonitoringOccasionOfPEI”中的第二个数值确定。下面更加具体的描述在第一帧号确定的情况下如何根据第一索引确定PEI的资源位置。
UE根据寻呼搜索空间和“DownlinkConfigCommonSIB”字域配置的第一PEI的PDCCH监听机会“firstPDCCH-MonitoringOccasionOfPEI”和一个SSB对应的paging PDCCH MO个数“nrofPDCCHMonitoringOccasionPerSSB-InPO”来确定PEI的PDCCH监听机会。当寻呼搜索空间配置“SearchSpaceId=0”时,PEI的PDCCH监听机会与剩余最小系统信息(Remaining Minimum SI,RMSI)相同。
当寻呼搜索空间配置配置的“SearchSpaceId”不等于0时,UE监听第(PEI_i_s+1)个PEI。PEI是一组“S*X”个连续的PDCCH监听机会,其中S是根据SIB1承载的SSB位置信息确定实际传输的SSB的数目,X表示“nrofPDCCHMonitoringOccasionPerSSB-InPEI”配置的每个SSB对应的PDCCH MO个数,如果该值不配置则X等于1。当配置了“firstPDCCH-MonitoringOccasionOfPEI”时,第(PEI_i_s+1)个PEI的PDCCH MO的起始点为高层参数“firstPDCCH-MonitoringOccasionOfPEI”的第(PEI_i_s+1)个值,否则,第(PEI_i_s+1)个PEI的PDCCH MO的起始点等于PEI_i_s*S*X。
根据上述方法,UE和gNB可以根据确定的第一帧号以及第一索引确定PEI的资源位置,该PEI为UE需要监听的PEI,该PEI用于指示UE需要监听的PO的寻呼情况。所述实施例五给出了根据第一帧号和第一索引确定PEI的资源位置的方法,对于UE来说确定方式更加简单,对于协议影响更少。
本申请实施例还提供一种寻呼提前指示的传输方法,应用于网络侧设备,如图10所示,包括:

需要说明的是,网络侧设备确定PEI的资源位置后,在所述资源位置发送PEI,所述PEI可以用于指示寻呼的存在情况,即存在寻呼或者不存在寻呼均通过PEI指示;或者,在不存在寻呼时,所述网络侧设备在确定的所述资源位置不发送PEI。

以所述第四参数满足(T div N),所述第五参数满足floor((UE_ID mod N)/A),所述第六参数满足A=max(X/Ns,1)或A=max(floor(X/Ns),1)为例,则所述第一帧号满足如下公式:
