在移动通信系统中,当网络设备需要向处于空闲状态的终端设备发送下行数据和/或更新系统信息时,网络设备可以寻呼终端设备,网络设备可以在寻呼周期内的寻呼帧(paging frame,PF)中的每个寻呼检测机会(paging monitoring occasion,PMO)资源上发送用于调度寻呼消息的下行控制信息(downlink control information,DCI),使得在各个PMO资源上通过不同波束发送的该DCI能够覆盖该网络设备的服务范围。终端设备通过依次在每个PMO资源上检测该DCI,以基于检测到的该DCI获取寻呼消息。
然而,对于覆盖面积大、服务波束数目多的网络设备,如需要上百个服务波束覆盖满足接入条件的覆盖面积的网络设备,需要在上百个PMO资源上发送一个终端设备的用于调度寻呼消息的DCI,相应地,终端设备需要在上百个PMO资源上检测是否存在该DCI,资源开销及功耗过大。

目前,终端设备在非连续接收(discontinuous reception,DRX)周期内的寻呼帧(paging frame PF)上检测用于调度寻呼消息的下行控制信息(downlink control information,DCI),DRX周期也可以称为寻呼周期。如图3所示,一个DRX周期T内,可以包括NPF个PF,一个PF是一个无线帧,PF的系统帧号(system frame number,SFN)满足下式:
(SFN+PF_offset)mod T=(T div NPF)*(UE_ID mod NPF),
T div NPF表示将一个DRX周期T等分成NPF个系统帧组后,每个系统帧组包含的系统帧数。UE_ID为终端设备的标识(identifier,ID),该NPF个系统组中的第(UE_ID mod N)个系统组中的第一个系统帧为PF。
网络设备会为终端设备配置DRX周期T,如该周期T可以是32个无线帧(radio frame)、64个无线帧等,以及网络设备还会为终端设备配置上述用于确定寻呼帧数量的NPF,NPF的取值可以是T、T/2、T/4、T/8、T/16。
一个PF中包括Ns个寻呼机会(paging occasion,PO),PO是物理下行控制信道(physical downlink control channel,PDCCH)监听机会(PDCCH monitoring occasion,PMO)资源的集合,PO的索引i_s满足下式:
i_s=floor(UE_ID/NPF)mod Ns
其中,floor(UE_ID/N)表示对UE_ID除以N的结果向下取整。每个PO包括连续的S个时隙内的PMO资源,S是一个同步信号块和物理广播信道(physical broadcast channel,PBCH)块(synchronization signal and PBCH block,SSB)突发组(burst set)块中实际广播的SSB的个数。
如图3所示,S=8,PO包括分别位于连续的8个时隙内的PMO资源,即时隙0至时隙7这8个时隙中分别依次包括PMO资源0至PMO资源7。该8个PMO资源与一个SSB突发组中的实际广播的8个SSB依次对应,每个PMO资源上采用相对应的SSB的发送波束方向发送用于调度寻呼消息的DCI,该DCI承载在PMO资源中的PDCCH上。或者说,在每个PMO资源中的PDCCH上采用对应的SSB的发送波束方向发送用于调度寻呼资源的DCI。
当网络设备需要向终端设备发送寻呼消息时,由于网络设备不确定终端设备位于哪个SSB的波束范围内,网络设备在一个PO中的每个PMO资源上通过相应的SSB发送波束方向发送用于调度寻呼消息的DCI,使得DCI覆盖到该网络设备的服务范围。相应地,终端设备在每个PMO资源上检测网络设备发送的用于调度寻呼消息的DCI。网络设备会为终端设备配置寻呼-无线网络临时标识(paging radio network temporary identifier,P-RNTI),网络设备向该终端设备发送的用于调度寻呼消息的DCI通过P-RNTI加扰,终端设备可以根据该P-RNTI检测用于调度该终端设备的寻呼消息的DCI。该DCI调度了承载寻呼消息的PDSCH,终端设备接收到该DCI后,在该DCI调度的PDSCH上接收寻呼消息。
然而,对于覆盖面积大、服务波束数目多的网络设备。例如,非陆地网络(non-terrestrial networks,NTN)中网络设备,以卫星作为NTN中网络设备为例,对于轨道高度508km的低轨C波段卫星,能够满足接入条件的覆盖面积为1万平方公里左右,当波束宽度为4.6度时,需要由650个左右的服务波束覆盖满足接入条件的覆盖面积。若对于覆盖面积大、服务波束数目多的网络设备仍采用上述寻呼方式,网络设备需要在上百个PMO资源上发送一个终端设备的用于调度寻呼消息的DCI,相应地,终 端设备需要在上百个PMO资源上检测是否存在该DCI。终端设备的功耗开销过大。
本申请提供了一种寻呼方法,终端设备可以根据其所处位置,确定相应的PMO资源,则终端设备所处位置相应的该PMO资源上检测用于调度寻呼消息的DCI。能够减小终端设备的功率消耗。以及,终端设备可以向网络设备上报所处位置相关的信息,使得网络设备可以根据终端设备所处的位置,在该位置相应的PMO资源上发送该终端设备的用于调度寻呼消息的DCI。能够减小网络设备的功率消耗,提高资源利用率。
图4是本申请实施例提供的寻呼方法的一个示意性流程图。
S401,终端设备根据终端设备当前位置所在的第一位置区域和第一对应关系,确定第一PMO资源,该第一对应关系中多个位置区域与多个PMO资源相对应,第一位置区域在第一对应关系中与第一PMO资源相对应。
终端设备可以获取终端设备当前位置的位置信息,比如,终端设备可以接收定位信号,根据定位信号得到终端设备当前所在位置的位置信息。该定位信号可以是来自如图4所示的网络设备或者来自用于定位的其他网络设备,如定位卫星。终端设备根据当前位置信息,可以确定终端设备当前位置处于第一对应关系中多个位置区域中的第一位置区域,该第一位置区域在第一对应关系中与第一PMO资源相对应,则终端设备可以确定在该第一PMO资源上检测用于调度该终端设备的寻呼消息的DCI。
可选地,网络设备向终端设备发送第一信息,该第一信息用于指示该第一对应关系。相应地,终端设备接收来自网络设备的该第一信息,确定该第一对应关系。
例如图5所示,该网络设备的服务范围覆盖位置区域0至位置区域N,网络设备可以确定位置区域与PMO资源的第一对应关系,如第一对应关系中位置区域0与PMO资源0相对应,位置区域1与PMO资源1对应,…,位置区域N与PMO资源N相对应。网络设备通过第一信息为终端设备配置覆盖区域内的每个位置区域对应的PMO资源,N为正整数。终端设备可以根据所处的第一位置区域和第一对应关系,确定第一PMO。使得处于一个位置区域的终端设备可以仅在该位置区域对应的PMO资源上检测寻呼DCI,不需要在每个PMO资源上检测寻呼DCI,能够减小终端设备的功率消耗。
示例性地,网络设备可以通过第一信息指示经度坐标和纬度坐标的方式为终端设备配置该N个位置区域,终端设备根据第一信息指示的经度坐标和纬度坐标,确定该N个位置区域。或者,可以预定义的方式预定义位置区域及相应的标识,网络设备通过第一信息指示位置区域的标识的方式通知终端设备该N个位置区域。终端设备根据第一信息中指示的N个标识确定相应的N个位置区域。或者,网络设备可以通过其他方式指示位置区域,本申请对此不作限定。需要说明的是,不同位置区域大小可以不同,且本申请对位置区域的形状不作限定,可以根据具体实施需求进行实施。
一种实施方式中,该第一信息承载在主信息块(master information block,MIB)中。
例如,终端设备接收来自网络设备的SSB,获取承载在该SSB中的PBCH上的MIB,从而根据MIB的第一信息确定该第一对应关系。
另一种实施方式中,该第一信息承载在系统信息块(system information block,SIB)中。可选地,终端设备接收来自网络设备的第一信息,包括:终端设备接收第一同步信号块,并根据该第一同步信号块,接收来自网络设备的系统信息块,该系统信息块中包括第一信息。
例如,终端设备接收来自网络设备的SSB,根据SSB中的MIB接收SIB1。比如,该SIB1中包括该第一信息,终端设备根据该SIB1中的第一信息确定该第一对应关系。或者,该SIB1中包括承载其他系统信息(other system information,OSI)的其他SIB的调度信息,终端设备根据该调度信息接收其他SIB,其他SIB包括SIB2至SIB9中的一项或多项。第一信息可以作为OSI承载在SIB2至SIB9中的至少一个SIB中,终端设备根据第一信息确定该第一对应关系。终端设备确定第一对应关系后,根据当前位置所在的第一位置区域和第一对应关系,确定第一PMO资源。本申请对此不作限定。
S402,终端设备在该第一PMO资源上检测DCI,该DCI用于调度寻呼消息。
若网络设备需要向终端设备发送寻呼消息,网络设备在第一PMO资源上向终端设备发送了寻呼DCI。终端设备可以在第一PMO资源上检测到该DCI,例如,终端设备根据网络设备为终端设备配置的P-RNTI,网络设备发送给终端设备的寻呼DCI通过该P-RNTI加扰,例如可以是P-RNTI作为绕码对该DCI中的循环冗余校验(cyclic redundancy check,CRC)字段进行加扰。终端设备在PMO资源上检测是否存在P-RNTI加扰的DCI,若检测到P-RNTI加扰的DCI,该DCI指示了承载寻呼消息的PDSCH,以及用于解调解码寻呼消息的相关参数。终端设备可以根据该DCI确定承载寻呼消息的 PDSCH资源,并在该PDSCH资源上接收来自网络设备的寻呼消息。若未检测到P-RNTI加扰的DCI,则终端设备认为网络设备未发送寻呼DCI。
若终端设备在第一PMO资源上检测到了来自网络设备的寻呼DCI,终端设备根据在第一PMO资源上接收到的该寻呼DCI,确定承载寻呼消息的PDSCH,从而在该PDSCH上接收来自网络设备的寻呼消息。
可选地,终端设备由第一位置区域移动至第二位置区域。终端设备根据第二位置区域和该第一对应关系,确定第二位置区域对应的第二PMO资源。终端设备在第二PMO资源检测寻呼DCI。
若终端设备发生移动,如终端设备所处位置由第一对应关系中的第一位置区域移动至第二位置区域,则终端设备可以根据第一对应关系,确定第二位置区域对应的第二PMO资源,则终端设备在第二位置区域内在第二PMO资源上检测用于调度终端设备的寻呼消息的DCI。
在图4所示实施例中,网络设备需要寻呼终端设备时,可以在每个PMO资源上发送寻呼DCI,终端设备在第一PMO资源上可以检测到该寻呼DCI。或者,网络设备可以根据终端设备当前位置所在的第一位置区域和第一对应关系,确定第一PMO资源,在第一PMO资源上向终端设备发送寻呼DCI,能够减小网络设备的功率消耗,以及提高资源利用率。终端设备可以向网络设备发送信息1,该信息1用于指示终端设备的位置,如信息1可以是终端设备当前位置的位置信息,或者,该信息1用于指示第一位置区域。网络设备通过该信息1确定终端设备当前位于第一位置区域。
例如,该信息1是终端设备当前位置的位置信息,网络设备接收到该信息1后,可以根据终端设备的当前位置的位置信息,确定终端设备位于第一对应关系中的多个位置区域中的第一位置区域,则网络设备可以确定第一位置区域对应的第一PMO资源,则网络设备可以确定终端设备在第一PMO资源上检测用于调度寻呼消息的DCI,下文中将调度寻呼消息的DCI简称为寻呼DCI,但本申请对该DCI在具体实施中的名称不作限定。当网络设备需要向终端设备发送寻呼消息时,网络设备可以在该第一PMO资源上向终端设备发送寻呼DCI。
再例如,该信息1用于指示第一位置区域,网络设备接收到该信息1后,确定终端设备位于第一位置区域,则根据第一对应关系可以确定第一PMO资源。当网络设备需要向终端设备发送寻呼消息时,网络设备可以在该第一PMO资源上向终端设备发送寻呼DCI。
可选地,终端设备移动至第二位置区域后,终端设备向网络设备发送第二信息,该第二信息用于指示终端设备移动至的位置,或者,该第二信息用于指示第二位置区域。
相应地,网络设备接收到来自终端设备的第二信息后,确定终端设备移动至第二位置区域,终端设备用于检测寻呼DCI的PMO资源由第一PMO资源变更为第二位置区域对应的第二PMO资源。网络设备需要向终端设备发送寻呼消息时,在第二PMO资源上向终端设备发送寻呼DCI。
图4所示实施例既可以适用于网络设备是凝视模式卫星的场景中又可以适用于网络设备是非凝视模式卫星的场景中,网络设备可以根据终端设备所处的位置区域确定终端设备检测寻呼DCI的PMO资源,并且在网络设备需要向终端设备发送寻呼消息时,网络设备可以根据终端设备所处的位置区域,确定波束方向对应终端设备所处的位置区域的发送波束,即该发送波束的覆盖范围包括该位置区域,通过该发送波束在终端设备检测寻呼DCI的PMO资源上向终端设备发送寻呼DCI,以及通过该发送波束在寻呼DCI指示的PDSCH上向终端设备发送寻呼消息。
凝视模式卫星是指该卫星的同一同步信号块(即同一索引标识的同步信号块)的覆盖范围在不同时间段均为同一位置区域,即同步信号块的覆盖范围不随时间变化。例如图6所示,作为网络设备的凝视模式卫星的服务范围内包括N个SSB(即同步信号块的一个示例)提供接入、同步服务,该网络设备的SSB与位置区域的对应关系保持不变,即SSB的覆盖范围覆盖的位置区域保持不变。如图6所示,SSB 0对应位置区域0、SSB 1对应位置区域1、….、SSB N对应位置区域N。若终端设备处于位置区域1,则网络设备可以采用与SSB 1的发送波束的波束方向一致的发送波束在位置区域1对应的PMO资源上向终端设备发送寻呼DCI以及在寻呼DCI指示的PDSCH上发送寻呼消息。
非凝视模式卫星是指该卫星的同一同步信号块(即同一索引标识的同步信号块)的波束方向(如波束权值)不随时间变化,但覆盖范围会随时间变化。即同一同步信号块的波束覆盖的位置区域会随时间变化。例如图7所示,作为网络设备的非凝视模式卫星的服务范围内的N个SSB在第一时间段和第二时间段对应的位置区域不同,如图7所示,在第一时间段,SSB0对应位置区域0、SSB 1对应位置区域1、….、SSB N对应位置区域N。而在第二时间段,SSB0对应位置区域1、SSB 1对应位置区 域2、….、SSB N对应位置区域N+1。若终端设备在第一时间段和第二时间段均处于位置区域1,终端设备与网络设备可以根据第一对应关系确定在位置区域1对应的PMO资源1检测寻呼DCI。若网络设备需要在第一时间段向终端设备发送寻呼消息,则网络设备可以采用在第一时间段内波束方向覆盖位置区域1的SSB1对应的波束在PMO资源1上向终端设备发送寻呼DCI,以及在寻呼DCI指示的PDSCH上发送寻呼消息。终端设备可以在该PMO资源1上检测寻呼DCI以及根据DCI接收寻呼消息。若网络设备需要在第二时间段向终端设备发送寻呼消息,则网络设备可以采用在第二时间段内波束方向覆盖位置区域1的SSB2对应的波束在PMO资源1上向终端设备发送寻呼DCI,以及在寻呼DCI指示的PDSCH上发送寻呼消息。终端设备可以在该PMO资源1上检测寻呼DCI以及根据DCI接收寻呼消息。
图8是本申请实施例提供的寻呼方法的另一个示意性流程图。
S801,终端设备根据第一同步信号块和第二对应关系,确定第一PMO资源,该第二对应关系中多个同步信号块与多个寻呼检测机会资源相对应,第一同步信号块在第二对应关系中与第一PMO资源相对应,第一同步信号块用于终端设备与网络设备实现下行时频同步。
示例性地,同步信号块可以是SSB,例如网络设备在其服务范围内包括N个SSB,N为正整数,每个SSB为其波束覆盖范围内的终端设备提供接入、同步等网络服务,终端设备可以根据SSB1实现与网络设备的下行时频同步。
例如,该第一同步信号块可以是终端设备能够接收到的来自网络设备的多个同步信号块中信号质量最高的同步信号块。同步信号块的信号质量可以包括但不限于同步信号块(如具体可以是同步信号块中的同步信号)的接收信号强度指示(received signal strength indicator,RSSI)、参考信号接收功率(reference signal receiving power,RSRP)、参考信号接收质量(reference signal receiving quality,RSRQ)或信号与干扰加噪声比(signal to interference plus noise ratio,SINR)中的一项或多项。
终端设备可以确定第二对应关系中与第一同步信号块对应的第一PMO资源,从而确定在该第一PMO资源上检测寻呼DCI。
可选地,网络设备向终端设备发送第四信息,该第四信息用于指示该第二对应关系。相应地,终端设备接收来自网络设备的该第四信息,并根据该第四信息确定该第二对应关系。
网络设备可以确定SSB与PMO资源的第二对应关系,如第二对应关系中SSB 0与PMO资源0相对应,SSB 1与PMO资源1对应,…,SSB N与PMO资源N相对应。网络设备通过第四信息为终端设备配置每个SSB对应的PMO资源,在一个SSB的波束覆盖范围内的终端设备可以在该SSB对应的PMO资源接收上寻呼DCI。使得终端设备可以根据其能够接收到的信号质量最高的同步信号块(即第一同步信号块)和第二对应关系,确定第一PMO资源。使得该终端设备可以仅在第一同步信号块对应的PMO资源上检测寻呼DCI,不需要在每个PMO资源上检测寻呼DCI,能够减小终端设备的功率消耗。
一种实施方式中,该第四信息承载在SIB中。

在图8所示实施例中,网络设备需要寻呼终端设备时,可以在每个PMO资源上发送寻呼DCI,终端设备在第一PMO资源上可以检测到该寻呼DCI。或者,网络设备根据第一同步信号块和第二对应关系,确定终端设备检测用于调度寻呼消息的DCI的第一PMO资源。能够减小网络设备的功率消耗,以及提高资源利用率。
终端设备可以向网络设备发送信息2,网络设备根据信息2确定终端设备用于时频同步的同步信号块为第一同步信号块。可选地,该信息2用于指示以下一项或多项:
第一同步信号块、第一PMO资源、终端设备当前位置的位置信息,或第一位置区域,
其中,第一同步信号块的覆盖范围是第一位置区域,或者说第一位置区域是终端设备接收第一同步信号块所在的位置区域。
例如,信息2用于指示第一同步信号块,终端设备通知网络设备当前用于时频同步的同步信号块为第一同步信号块,使得网络设备能够根据服务终端设备的第一同步信号块和第二对应关系,确定终端设备检测寻呼DCI的PMO资源为第一PMO资源。能够实现网络设备与终端设备对终端设备检测寻呼DCI的PMO资源达成共识,提高寻呼的可靠性。
再例如,信息2用于指示终端设备当前位置的位置信息或第一位置区域,网络设备接收到该信息2后,可以根据终端设备当前位置的位置信息或第一位置区域,确定终端设备处于第一同步信号块的覆盖范围内,再基于第一同步信号和第二对应关系,确定终端设备检测寻呼DCI的第一PMO资源。从而实现网络设备与终端设备对终端设备检测寻呼DCI的PMO资源达成共识。
信息2也可以指示第一同步信号块、第一PMO资源、终端设备当前位置的位置信息,或第一位置区域中的多项,比如信息2可以指示第一同步信号块和第一PMO资源,或者包括第一同步信号块和终端设备的当前位置的位置信息。本申请对此不作限定。
终端设备可以根据但不限于以下实施方式确定第一位置区域与第一同步信号块相对应。
一种实施方式中,终端设备接收到的同步信号块中信号质量最强的同步信号块为第一同步信号块,确定终端设备的当前位置或所处的第一位置区域与第一同步信号块相对应。
例如,终端设备可以根据终端设备能够接收到的网络设备的同步信号块中信号质量最高的同步信号块为第一同步信号块,确定终端设备在第一同步信号块的波束覆盖范围内,从而确定终端设备的当前位置或所处的第一位置区域与第一同步信号块相对应。
另一种实施方式中,终端设备根据第三对应关系,确定第一位置区域与第一同步信号块相对应,其中,第三对应关系为多个同步信号块与多个位置区域之间的对应关系,第一位置区域在第三对应关系中与第一同步信号块相对应。
可选地,网络设备可以向终端设备发送信息3,该信息3用于指示该第三对应关系。相应地,终端设备接收该信息3,确定该第三对应关系。
例如,第三对应关系可以如表1所示,终端设备可以根据移动后所处位置的位置信息,确定终端设备目前处于第三对应关系中的多个位置区域的第一位置区域,从而确定第一位置区域对应的第一同步信号块。终端设备可以再根据第一同步信号块与和第二对应关系,确定第二对应关系中第二同步信号块对应的第二PMO资源。
表1
可选地,第二对应关系可以包括第三对应关系。
第二对应关系中包括同步信号块与PMO资源的对应关系以外,还包括同步信号块与位置区域的对应关系,即第二对应关系包括同步信号块、PMO资源和位置区域三者的对应关系。
例如,第二对应关系可以如表2所示,其中第一同步信号、第一PMO资源和第一位置区域之间相互对应,第二同步信号、第二PMO资源和第二位置区域之间相互对应。终端设备可以根据当前位置的位置信息确定位于第二对应关系中的第一位置区域,从而根据第二对应关系,确定第一位置区域对应的第一PMO资源。
表2
网络设备根据第一同步信号块和第二对应关系,确定第一PMO资源后,若网络设备需要向终端设备发送寻呼消息,则网络设备在第一PMO资源上发送DCI,该DCI用于调度寻呼消息。相应地,终端设备在第一PMO资源上接收来自网络设备的DCI。能够减小网络设备和终端设备的功率消耗、提高资源利用率。
可选地,终端设备由第一位置区域移动至第二位置区域,该第一位置区域是第一同步信号块对应的位置区域。终端设备根据第二位置区域对应的第二同步信号块和第二对应关系,确定第二PMO资源。终端设备在第二PMO资源上检测用于调度寻呼消息的DCI。
如该第一同步信号块的波束覆盖范围为第一位置区域,该第二同步信号块的波束覆盖范围为第二位置区域。当终端设备发生移动,由第一同步信号块的波束覆盖范围移动至第二同步信号块的波束覆盖范围,终端设备可以根据第二对应关系,确定第二同步信号块对应的第二PMO资源,从而确定检测寻呼DCI的PMO资源由第一PMO资源变更为第二PMO资源。终端设备在第二同步信号块的波束覆盖范围内在第二PMO资源上检测该终端设备的寻呼DCI。
例如,终端设备在移动后无法接收到第一同步信号块,而当前能够接收到的同步信号块中信号质量最高的同步信号块为第二同步信号块。或者终端设备在移动后仍能够接收到第一同步信号块,但当前能够接收到的同步信号块中信号质量最高的同步信号块为第二同步信号块,即第一同步信号块的信号质量低于第二同步信号块的信号质量。则终端设备确定当前能够接收到的同步信号快中信号质量最高的同步信号块为第二同步信号块,终端设备可以确定由第一同步信号块的覆盖区域(即第一位置区域)移动至第二同步信号块的覆盖区域(即第二位置区域),因此,终端设备确定在第二同步信号块对应的第二PMO资源上检测寻呼DCI。或者,终端设备可以根据第三对应关系,确定终端设备移动至的位置处于第三对应关系中的第二位置区域,从而确定第二位置区域在第三对应关系中对应的第二同步信号块,再根据第二同步信号块和第二对应关系,确定第二同步信号块对应的第二PMO资源。
可选地,终端设备向网络设备发送第五信息,该第五信息用于指示以下一项或多项:
第二同步信号块、第二PMO资源、终端设备移动至的位置,或第二位置区域。
终端设备发生移动后或者变更用于检测寻呼DCI的PMO资源后,可以向网络设备第五信息,以便网络设备可以根据第五信息确定终端设备发生移动,并确定终端设备移动后检测寻呼DCI的第二PMO资源。第五信息的具体实施方式可以参考前文中信息2的描述,也就是说,第五信息与信息2是同一类型(或同一信息格式)但承载具体信息内容不同的两个信息。
终端设备在第二同步信号的覆盖范围内在第二PMO资源上检测来自网络设备的寻呼DCI,网络设备在需要向终端设备发送寻呼消息的情况下,网络设备在第二PMO资源上向终端设备发送寻呼DCI,通知终端设备承载寻呼消息的PDSCH,以便终端设备能够根据在第二PMO资源上检测到的该寻呼DCI接收寻呼消息。
图8所示实施例适用于网络设备是凝视模式卫星的场景,即网络设备的同一索引标识的同步信号的覆盖的位置区域不随时间变化。终端设备在其用于时频同步的同步信号覆盖范围内,在该同步信号对应的PMO资源上检测寻呼DCI。网络设备在需要向终端设备发送寻呼消息的情况下,可以采用该同步信号对应的发送波束在该同步信号对应的PMO资源上向终端设备发送寻呼DCI,以及通过该发送波束在寻呼DCI指示的PDSCH上向终端设备发送寻呼消息。
图9是本申请实施例提供的寻呼方法的另一个示意性流程图。图9所示实施例提供了一种当网络设备的同一索引标识的同步信号的覆盖的位置区域随时间变化时终端设备检测寻呼DCI的方案。该方法包括但不限于如下步骤:
S901,终端设备根据第四对应关系和第一同步信号块,确定第一PMO资源,第四对应关系包括多个同步信号块与多个PMO资源在多个时间段中的每个时间段内的对应关系,该第一同步信号块用于终端设备与网络设备实现下行时频同步,该第一同步信号块在第一时间段内与第一PMO资源相对应,第一时间段是终端设备接收到第一同步信号块的时刻所属的时间段。
例如,网络设备是如图7所示的非凝视模式卫星,该网络设备服务范围内的N个SSB在不同时间段内覆盖的位置区域不同。如图7所示,在第一时间段内SSB 0至SSB N依次对应位置区域0至位置区域N,在第二时间段内SSB 0至SSB N依次对应位置区域1至位置区域N+1。网络设备可以确定不同时间段内每个SSB与PMO资源的第四对应关系。网络设备可以根据每个时间段内N个SSB覆盖的位置区域,确定第四对应关系。示例性地,第四对应关系可以如表3所示,如t0时刻至t1时刻的时间段(记作[t0,t1)时间段,该时间段可以是包括t0时刻不包括t1时刻,但本申请不限于此)内SSB 0至SSB N依次覆盖位置区域0至位置区域N,则网络设备可以确定在[t0,t1)时间段内SSB 0至SSB N依次对应PMO资源0至PMO资源N,如表3所示。以及在t1时刻至t2时刻的时间段(记作[t1,t2)时间段)内SSB 0至SSB N依次覆盖位置区域1至位置区域N+1,则网络设备可以确定在[t1,t2)时间段内 SSB 0至SSB N-1依次对应PMO资源1至PMO资源N,而SSB N对应PMO资源0。可以理解为,该N个SSB在不同时间段内依次循环对应该PMO资源0至PMO资源N。则在时间段[t2,t3)时间段(表3未示出)内SSB 0至SSB N-2依次对应PMO资源2至PMO资源N,而SSB N-1、SSB N分别依次PMO资源0、PMO资源1。其他时间段可以同理依次类推。
表3
可选地,网络设备向终端设备发送第六信息,该第六信息用于指示该第四对应关系。
网络设备可以通过第六信息向终端设备通知该第四对应关系,终端设备可以根据当前用于时频同步的SSB和接收到该SSB的时间段,确定该时间段内检测寻呼DCI的PMO资源。

可选地,终端设备接收来自网络设备的第六信息,包括:终端设备接收第一同步信号块,并根据第一同步信号块,接收来自网络设备的系统信息块,该系统信息块包括第六信息。
作为示例非限定,该SIB为SIB1或OSI。具体可以参考图4所示实施例中系统信息块包括第一信息的实施方式,为了简要,在此不再赘述。
以下示例性地提供了网络设备通过第六信息指示第四对应关系时,第六信息指示第四对应关系中的时间段的方式,应理解,本申请并不限于此。
一个示例中,第六信息通过指示绝对时刻指示时间段,如第六信息指示每个时间段的起始时刻和结束时刻,或者指示每个时间段的起始时刻和持续时长。本申请实施例第六信息还是的绝对时刻和持续时长的精度不作限定,如绝对时刻和/或持续时长可以是秒、毫秒或微秒。
另一个示例中,第六信息可以通过指示与参考帧之间偏移量指示每个时间段的起始时刻和结束时刻。参考帧可以是预定义的或网络设备预配置的。例如,参考帧为系统帧号(system frame number,SFN)为m的系统帧,记作SFN m,第六信息可以指示一个时间段的起始时刻相较于SFN m偏移的时间单元的个数x,以及结束时刻相较于SFN m偏移的时间单元的个数y,y>x。作为示例非限定,时间单元为系统帧、子帧、时隙或OFDM符号。比如,时间单元为系统帧,则终端设备可以根据第六信息确定该时间段为SFN m+x至SFN m+y。或者,第六信息可以指示一个时间段的起始时刻相较于SFN m偏移的时间单元的个数x,以及该时间段持续的时间单元的个数z。比如,该时间单元为系统帧,则终端设备可以根据第六信息确定该时间段为SFN m+x至SFN m+x+z。
S902,终端设备在该第一PMO资源上检测DCI,该DCI用于调度寻呼消息。
上述S902的具体实施方式可以参考前文中对图4所示的S402的描述,为了简要,在此不再赘述。
在图9所示实施例中,网络设备需要寻呼终端设备时,可以在每个PMO资源上发送寻呼DCI,终端设备在第一PMO资源上可以检测到该寻呼DCI。或者,网络设备根据第四对应关系和第一同步信号块,确定终端设备检测用于调度寻呼消息的DCI的第一PMO资源。能够减小网络设备的功率消耗,以及提高资源利用率。
可选地,终端设备向网络设备发送信息4,该信息4用于指示以下一项或多项:
第一同步信号块、第一时间段、终端设备当前位置的位置信息、或第一位置区域,
其中,第一位置区域为第一同步信号的覆盖范围,终端设备当前位置的位置信息属于第一位置区域。
相应地,网络设备接收来自终端设备的信息4和第四对应关系,确定终端设备检测寻呼DCI的第 一PMO资源。
例如,第四对应关系如表4所示,终端设备[t0,t1)时间段内接收到SSB1,则终端设备可以在[t0,t1)时间段(即第一时间段的一个示例)内向网络设备发送信息4,该信息4指示SSB1(即第一同步信号块的一个示例),网络设备在[t0,t1)时间段内接收到该信息4,则网络设备可以根据终端设备在[t0,t1)时间段内接收到SSB1和第四对应关系,确定终端设备在[t0,t1)时间段内检测寻呼DCI的PMO资源1(即第一PMO资源的一个示例)。
再例如,终端设备向网络设备发送的信息4可以包括第一时间段和第一同步信号块,使得网络设备可以根据第四对应关系、第一时间段和第一同步信号块,确定第四对应关系中第一同步信号块在第一时间段对应的第一PMO资源。
再例如,终端设备向网络设备发送的信息4可以指示终端设备当前位置或第一位置区域,使得网络设备能够根据第四对应关系,确定终端设备在当前时间段(即第一时间段)内处于第一同步信号块的覆盖范围内,从而确定终端设备在第一时间段内检测寻呼DCI的第一PMO资源。
网络设备需要向终端设备发送寻呼消息时,在第一PMO资源上发送寻呼DCI。相应地,终端设备在第一PMO资源上接收来自网络设备的DCI。能够减小网络设备和终端设备的功率消耗,以及提高资源利用率。
在上述实施例中,网络设备的覆盖范围内的每个位置区域均需要对应一个PMO资源,或者每个同步信号块均需要对应一个PMO资源,网络设备通过每个位置区域对应的波束方向的发送波束(如位置区域对应的同步信号块的发送波束),在相应的PMO资源上发送寻呼DCI,使得在相应位置区域的终端设备能够在对应的PMO资源上检测到各自的寻呼DCI。然而,对于覆盖范围大的网络设备,如NTN网络中的卫星作为网络设备,需要的PMO资源的数量在百个以上,若多个PMO资源在时域上连续,将会影响数据通信的连续性、造成较大的数据通信时延等。因此,本申请提出可以对PMO资源进行分组,不同的PMO资源组之间具有一定的时间间隔。同一PMO资源组中的PMO资源可以分别位于连续的时间单元中,或者可以位于不连续的时间单元中。时间单元可以是正交频分多址(orthogonal frequency division multiplexing,OFDM)符号组
可选地,上述实施例中多个PMO资源(如上述实施例中第一对应关系至第四对应关系中的多个PMO资源)为多个资源组中的PMO资源,在时间上相邻的两个资源组之间的间隔为第一时间间隔,该第一时间间隔是网络设备配置的。
例如图10所示,以子载波间隔为30kHz为例,每8个PMO资源为一个PMO资源组,如图10所示,一个系统帧包括20个时隙,则相邻两个PMO资源组之间的第一时间间隔为2个系统帧的帧长。
可选地,多个资源组包括在时间上相邻的第一资源组和第二资源组,该第一资源组与该第二资源组之间的第一时间间隔内包括一个同步信号块组,该同步信号块组中的M个同步信号块与第一资源组中的M个PMO资源一一对应,或者该同步信号块组中的M个同步信号块与该第二资源组中的M个PMO资源一一对应
例如图11所示,系统帧号(system frame number,SFN)n的系统帧(该系统帧记作SFN n)中的8个时隙分别包括一个PMO资源组中的8个PMO资源,SFN n+2中的8个时隙分别包括下一个PMO资源组中的8个PMO资源,该相邻两个PMO资源组之间间隔2个系统帧的帧长,该两个PMO资源组之间的SFN n+1中的前四个时隙中承载有包括SSB组,如一个时隙承载了2个SSB,则该4个时隙承载的SSB组中包括8个SSB。该8个SSB可以与SFN n+2中的PMO资源组中的8个PMO资源一一对应。图11所示的SFN n中的PMO组对应的SSB组可以在SFN n-1中发送传输。网络设备可以在一个PMO资源组之前发送该PMO资源组对应的SSB,以便终端设备可以根据该终端设备用于时频同步的SSB进行下行时频同步校准后,在相应的PMO资源上检测寻呼DCI。提高了寻呼终端设备的可靠性。
可选地,同步信号组与在时间上相邻的PMO资源组之间可以包括SIB1资源组,该SIB1资源组包括M个SIB1,该M个SIB1与同步信号块组中的M个SSB一一对应。
例如图12所示,SFN n+1中的前4个时隙包括一个SSB组中的8个SSB,以及该系统帧中还包括与该8个SSB一一对应的8个SIB1,每个SIB1通过对应的SSB的波束发送,终端设备根据接收到的一个SSB中的MIB可以确定相应的SIB1所在的时隙,并接收该SIB1。比如,该SIB1可以包括寻呼相关的配置信息,其中包括PMO资源的配置信息,终端设备在未确定用于检测寻呼DCI的PMO资源 时,可以根据SIB1确定用于检测寻呼DCI的PMO资源,从而可以在下个系统帧中相应的PMO资源上检测寻呼DCI。
可选地,同一PMO组中的相邻两个PMO资源所在时隙之间可以间隔至少一个时隙。该至少一个时隙可以用于承载OSI,或者,该至少一个时隙可以用于数据传输。
例如图12所示,在包含PMO资源的SFN n和SFN n+2中,相邻两个PMO资源所在时隙之间间隔一个时隙,PMO资源之间间隔的时域资源(如符号和/或时隙)可以用于承载OSI和/或用于数据传输。以及,如图12所示,在包含SIB1的SFN n+1中相邻SIB1所在时隙之间可以间隔一个时隙,SIB1之间间隔的时域资源(如符号和/或时隙)可以用于承载OSI和/或用于数据传输,但本申请不限于此。
可选地,同一PMO组中的相邻两个PMO资源可以分别包含在相邻两个时隙中,一个PMO组中的PMO资源分别包含在相邻的多个时隙中。
例如图13所示,在包含PMO资源的SFN n和SFN n+2中,同一PMO组中的8个PMO资源分别包含在连续的8个时隙中,而包含PMO资源的SFN(如SFN n和SFN n+2)中除PMO资源以外的资源可以作为PDSCH,如用于承载OSI和/或用于业务数据传输。
可选地,网络设备向终端设备发送第三信息,第三信息用于指示第一偏移量,该第一偏移量为寻呼周期的起始位置相较于帧号为0的系统帧之间的偏移量,第一偏移量大于系统帧的帧长。
相应地,终端设备接收来自网络设备的第三信息。如网络设备发送的寻呼相关的配置信息中包括该第三信息,通过第三信息指示第一偏移量,以便终端设备可以根据该第一偏移量和SFN 0的系统帧,确定终端设备寻呼周期的起始位置。该第一偏移量至少大于一个系统帧的帧长,使得可以在寻呼周期的起始位置之前发送第一个PMO组对应的SSB组。
对于覆盖范围较大的网络设备,由于需要覆盖服务范围的SSB的数量较多,相应的PMO资源的数量也较多,本申请实施例提供的如下两种PMO资源的配置方式。
方式一,一个SSB突发组包括S个SSB,每L个SSB为一个SSB组,一个SSB突发组共包括个SSB组,一个SSB组位于一个系统帧内,一个寻呼周期包括个PF,即NPF=L,每个PF中包括与一个SSB组对应的L个PMO资源。
以一个SSB突发组包括的SSB个数S为256为例,如网络设备采用如图11所示的传输方式,每8个SSB为一个SSB组,即L=8,256个SSB可以分为32组,因此,一个寻呼周期内需要包括32个PF。一组SSB组位于一个系统帧内,相邻两个SSB组之间间隔两个系统帧,则需要64个系统帧完成256个SSB的传输。由此可知,一个SSB突发组的周期为64个系统帧。因此,寻呼周期也应为64个系统帧,每两个SSB组所在的系统帧之间的间隔一个PF帧,则网络设备可以为终端设备配置寻呼周期T=64,NPF=T/2=32,那么T div NPF=2,即将一个寻呼周期内的64个系统帧分为32个系统帧组,每个系统帧组包括2个系统帧,且每个系统帧组内的第一个系统帧为PF。一个PF包括与PF之前的一个系统帧内的8个SSB一一对应的PMO资源,如图11所示。一个寻呼周期内的32个PF包括与256个SSB依次对应的256个PMO资源。
方式二,一个寻呼周期包括NPF个PF组,一个PF组中包括多个PF,一个PF组中的一个PF包括与一个SSB组对应的L个PMO资源,一个PF组包括与一个SSB突发组中的SSB一一对应的PMO资源。
也就是说,在方式二中,NPF用于确定PF组,相应地,为了满足上述配置需求可以增加NPF的可选值,如可以包括前文中描述的可选值以外,还可以包括T/32、T/64、T/128或T/256中的一种或多种可选值。其中,寻呼周期T的可选值可以包括32个系统帧、64个系统帧、128个系统帧和256个系统帧。
以一个SSB突发组包括的SSB个数S为256为例,如网络设备采用如图11所示的传输方式,网络设备可以配置寻呼周期T=128,NPF=T/64,则每个周期包括T div NPF=2,即2个PF组,一个PF组包括64个系统帧,如可以规定一个PF组中第二个系统帧开始每间隔两个系统帧为一个PF,如图13所示,一个PF组中的第一个系统帧是网络设备用于传输SSB突发组中的第一个SSB组(SSB 0至SSB7)的系统帧,第二个系统帧为该PF组中的第一个PF,即PF0,该PF0中包括与前一个系统帧中的8个SSB一一对应的PMO资源0至PMO资源7,与该PF0间隔两个系统帧的系统帧为该PF组中的第二个PF,即PF1,该PF1中包括与PF1之前的一个系统帧中的SSB 8至SSB 15一一对应的PMO资源8至PMO资源15,依次类推,该PF组中的最后一个系统帧为PF31,包括与PF31的前一个系统帧中 最后一个SSB组中的SSB 248至SSB 255一一对应的PMO资源248至PMO资源255。
根据上述两种方式终端设备可以确定与一个SSB突发组中的每个SSB对应的PMO资源的位置,终端设备可以根据终端设备所在位置区域或者用于时频同步的SSB,确定该终端设备用于检测寻呼DCI的PMO资源的位置,终端设备在每个寻呼周期内的该PMO资源上检测寻呼DCI。
