Abstract

Description

通信方法及装置 技术领域
本申请实施例涉及计算机领域，尤其涉及一种通信方法及装置。
背景技术
目前，用户设备(User Equipment，UE，又可称为终端)处在空闲态(RRC IDLE、RRC IDLE state、Idle state、Idle mode)时，为了能够接收到基站发送的寻呼消息，UE需要在特定的监听时机(Paging Occasion，PO)，监听基站采用扫波束发送的寻呼物理下行控制信道(Physical Downlink Control Channel，PDCCH)。在5G系统中，寻呼PDCCH可以是类型2-PDCCH公共搜索空间(Type2-PDCCH common search space set，Type2-PDCCH CSS set)配置的PDCCH。一般来说，Type2-PDCCH CSS set由高层参数配置，如paging Search Space，并且由P-RNTI进行CRC加扰。
在现有技术中，由于寻呼时机是针对一组UE的，因此当寻呼时机内的物理下行共享信道(Physical Downlink Share Chanel，PDSCH)承载的寻呼消息(paging message)并不针对某个UE，该UE仍然执行了寻呼PDCCH的监听和寻呼消息的接收的整个过程，却没有任何寻呼消息是该UE需要的(一般这种情形称为虚警或false alert)，这样的话，该UE浪费了电量在无用的接收上，导致该UE的耗电量较大。
另外，在5G系统中，UE需要在监听时机上监听基站采用扫波束(包括多个波束)向UE发送的寻呼PDCCH。UE根据对波束的检测或测量，选择在一个或多个波束上监听寻呼PDCCH。当UE选择在多个波束上监听寻呼PDCCH时，更加导致UE的耗电量较大。

具体实施方式
为使本申请实施例的目的、技术方案和优点更加清楚，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，所描述的实施例是本申请一部分实施例，而不是全部的实施例。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。
本申请所示的技术方案可以应用于第五代移动通信技术(the 5th generation mobile communication technology，5G)系统，也可以应用于长期演进(long term evolution，LTE)系统，还可以应用于通用移动通信系统(universal mobile telecommunications system，UMTS)陆地无线接入网(UMTS terrestrial radio access network，UTRAN)系统，或者全球移动通信系统(global system for mobile communication，GSM)/增强型数据速率GSM演进(enhanced data rate for GSM evolution，EDGE)系统的无线接入网(GSM EDGE radio access network，GERAN)架构。例如，5G系统中的车辆到所有(vehicle to X，V2X)系统、设备到设备(device to device，D2D)系统、机器型通信(machine type communication，MTC)系统等。
本申请所示的技术方案还可以应用于其它通信系统，例如5G系统的演进通信系统等，本申请对此不作限定。
图1为本申请提供的通信方法的应用场景示意图。如图1所示，通信系统中包括：基站101和用户设备102。其中，用户设备102为基站101所覆盖的服务小区中的用户设备。
可选地，用户设备102可以为移动电话(或称为“蜂窝”电话)或具有移动终端的计算机，例如，可以是便携式、袖珍式、手持式、计算机内置的或者车载的移动装置等。此外，用户设备102也可称为移动台(mobile station，MS)、终端(terminal)、终端设备(terminal equipment)。本申请中，示例性的以用户设备102的数量为4对通信方法的应用场景进行说明，并不在此限制用户设备102的具体类型和数量。
在实际应用中，基站101向用户设备102发送寻呼指示(Paging Indication，PI)物理下行控制信道(Physical Downlink Control Channel，PDCCH)或寻呼(Paging)PDCCH，用户设备102监听寻呼指示PDCCH或寻呼PDCCH以获取寻呼指示信息，若检测到寻呼指示PDCCH或寻呼PDCCH，则获取寻呼指示信息，若根据寻呼指示信息确定需要监听寻呼PDCCH或接收寻呼PDCCH调度的寻呼消息，则监听寻呼PDCCH或接收寻呼PDCCH调度的寻呼消息，以获取基站101发送给用户设备102的寻呼消息。在上述过程中，若根据寻呼指示信息确定需要监听寻呼PDCCH或接收寻呼PDCCH调度的寻呼消息，则监听寻呼PDCCH或接收寻呼PDCCH调度的寻呼消息，减少了用户设备监听寻呼PDCCH或接收寻呼PDCCH调度的寻呼消息的次数，进而节省用户设备的电量。
下面以具体地实施例对本申请的技术方案进行详细说明。下面这几个具体的实施例可以相互结合，对于相同或相似的概念或过程可能在某些实施例不再赘述。
图2为本申请实施例提供的一种通信方法的流程示意图。如图2所示，该通信方法包括：
S201：监听寻呼指示物理下行控制信道PDCCH。
可选地，本申请实施例的执行主体为可以用户设备，也可以为设置在用户设备中的通信装置。
可选地，该通信装置可以通过软件和/或硬件的结合来实现。
例如，当通信装置通过软件来实现时，通信装置可以为存储在芯片中存储区域里面的一段代码，芯片的处理器执行该段代码时，实现本申请中方法实施例中的步骤。
例如，当通信装置通过硬件来实现时，通信装置例如可以为芯片或者芯片模组等，通信装置中的各个模块可以包括上述芯片、芯片模组等硬件模块。当通信装置工作时，可以执行本申请中方法实施例中的步骤。
例如，当通信装置通过和硬件的结合来实现时，通信装置的各个模块包括芯片、芯片模组等硬件，以及存在芯片中的一段代码。当上述芯片、芯片模组工作时，执行上述代码，实现本申请中方法实施例中的步骤。
这里，寻呼指示PDCCH可以是一种类型的PDCCH，寻呼PDCCH也可以是一种类型的PDCCH。寻呼指示PDCCH可以不同于寻呼PDCCH。
一般来说，监听PDCCH也称为盲检PDCCH。用户设备在时频位置上监听或盲检PDCCH，但是基站在该时频位置上不一定发了PDCCH，因此用户设备只有通过CRC校验才能判断基站在是否该时频位置上发了PDCCH。一般PDCCH的CRC校验通过，称为用户设备检测到PDCCH，或用户设备成功检测到PDCCH，或用户设备检测PDCCH成功。
值得说明的是，寻呼指示PDCCH的循环冗余校验(Cyclic Redundancy Check，CRC)可以用新的无线网络临时标识(Radio Network Tempory Identity，RNTI)进行加扰。一般来说，用户设备可以对CRC进行某种类型的RNTI解扰，来确定是否成功检测到某种类型的PDCCH。例如，如果寻呼PDCCH对应P-RNTI(寻呼-RNTI)，那么用户设备可以对CRC进行P-RNTI解扰，来确定是否成功检测到寻呼PDCCH；如果寻呼指示PDCCH对应PI-RNTI(寻呼指示-RNTI)加扰，那么用户设备可以对CRC 进行PI-RNTI解扰，来确定是否成功检测到寻呼指示PDCCH。
在一种可能的设计中，监听寻呼指示PDCCH，包括：
在寻呼指示PDCCH监听时机上，监听所述寻呼指示PDCCH；
其中，寻呼指示PDCCH监听时机满足如下任意一个条件：
在第一时刻之前、且与第一时刻之间的偏移量为第一预设时长；或，
在第一时刻之后、且与第一时刻之间的偏移量为第一预设时长；
其中，第一时刻为同步信号块(SS/PBCH block，SSB)、信道状态信息参考信号(Channel State Information Reference Signal，CSI-RS)或者跟踪参考信号(Tracking Reference Signal，TRS)的起始时刻或结束时刻。具体地说，第一时刻为距离监听时机(Paging Occasion，PO)或监听时机内第一个寻呼PDCCH监听时机最近的同步信号块、信道状态信息参考信号或者跟踪参考信号(Tracking Reference Signal，TRS)的起始时刻或结束时刻。或者，第一时刻为监听时机或监听时机内第一个寻呼PDCCH监听时机之前、且距离监听时机或监听时机内第一个寻呼PDCCH监听时机最近的同步信号块、信道状态信息参考信号或者跟踪参考信号的起始时刻或结束时刻。或者，第一时刻为监听时机或监听时机内第一个寻呼PDCCH监听时机之后、且距离监听时机或监听时机内第一个寻呼PDCCH监听时机最近的同步信号块、信道状态信息参考信号或者跟踪参考信号的起始时刻或结束时刻。可选地，第一时刻为距离寻呼帧(Paging Frame，PF)最近的同步信号块、信道状态信息参考信号或者跟踪参考信号(Tracking Reference Signal，TRS)的起始时刻或结束时刻。或者，第一时刻为寻呼帧之前、且距离寻呼帧最近的同步信号块、信道状态信息参考信号或者跟踪参考信号的起始时刻或结束时刻。或者，第一时刻为寻呼帧之后、且距离寻呼帧最近的同步信号块、信道状态信息参考信号或者跟踪参考信号的起始时刻或结束时刻。所述同步信号块的起始时刻或结束时刻可以是同步信号块所在半帧(Half Frame)或帧(Frame)的起始时刻或结束时刻。
上述时刻可以为符号、时隙等。具体的，本申请中不限定上述时刻的具体取值。上述第一预设时长可以为1毫秒、2毫秒、1个时隙、2个时隙等。具体的，本申请中不限定第一预设时长的具体取值。在实际应用中，第一预设时长可以由实施本申请中提供的通信方法的通信系统中的高层参数提供，或者可以由用户设备通过其他高层参数推导出。第一预设时长也可以是固定时长。
本申请中，同步信号块、信道状态信息参考信号和跟踪参考信号为周期信号。其中，一个同步信号块由主同步信号(Primary Synchronization Signal，PSS)、辅同步信号(Secondary Synchronization Signal，SSS)和物理广播信道(Physical Broadcast Channel，PBCH)组成。每个同步信号块有一个预先确定的时域位置。该时域位置又可以称为候选的同步信号块。多个同步信号块组成一个同步信号突发(SS-burst)。多个同步信号突发组成一个同步信号突发集合(SS-burst-set)。Lmax个同步信号块的时域位置在一个5ms窗口内是固定的，其中，Lmax为大于或等于1的整数。Lmax个同步信号块的时域位置索引是连续排列的，例如：时域位置索引为从0到Lmax-1。因此一个同步信号块在这个5ms窗口内的发射时刻是固定的，索引也是固定的。一般来说，基站发送同步信号块时采用扫波束(beam sweeping)的方式，即基站通过不同波束在 不同时域位置上发送同步信号块，相应地，用户设备可以测量不同的波束，并感知在哪个波束上收到的信号最强。
在现有技术中，寻呼时机表示一组用户设备监听寻呼PDCCH的时间间隔(time interval)或时间窗口(time window)，而基站在一个寻呼时机内可能寻呼的是一个用户设备，但是，其他的用户设备仍然会检测到寻呼PDCCH(检测寻呼PDCCH并且循环冗余校验校验通过，或称成功检测到寻呼PDCCH，或称检测寻呼PDCCH成功)，并继而解码寻呼PDCCH调度的PDSCH承载的寻呼消息，寻呼消息内却并不包含这些其他的用户设备，这些其他的用户设备就会白白浪费了电量。而在本申请中，寻呼指示PDCCH可以在寻呼时机之前，指示后续寻呼时机内真正被寻呼的用户设备子组。或者说，一个寻呼时机对应的用户设备组可以进一步被分成用户设备子组，寻呼指示PDCCH用于指示用户设备子组有没有被寻呼。这样的话，减少了用户设备监听不必要的寻呼PDCCH的可能性，有利于用户设备节能。
需要说明的是，一个寻呼时机对应的用户设备组所分成的一个子组，可以称为一个用户设备子组。一般来说，对应一个寻呼时机或在一个用户设备组内的一个用户设备都会被基站配置一个用户设备子组。基站通过高层参数(高层信令)给该用户设备分配一个用户设备子组。该用户设备子组可能由一个位图内的一个比特表示，或者由一个编号(number)或索引(index)表示。
另一方面，有些用户设备的寻呼时机或寻呼PDCCH(一般在寻呼时机内)监听时机与上述周期信号(同步信号块、信道状态信息参考信号或跟踪参考信号)的时间间隔较长，从而使得寻呼指示PDCCH(一般在寻呼时机或寻呼PDCCH之前)监听时机与上述周期信号的时间间隔较长，这样的话，这些用户设备通过周期信号进行信道跟踪后需要保持一些模块的开启，以便寻呼指示PDCCH监听时机到来时及时监听寻呼指示PDCCH。在上述现有技术中用户设备通过周期信号进行信道跟踪后需要保持一些模块的开启，使得用户设备无法进入真正睡眠，必须等到以便在寻呼指示PDCCH监听时机到来时，监听寻呼指示PDCCH，导致用户设备的耗电量较大。因此，在本申请中，寻呼指示PDCCH监听时机在第一时刻之前、且与第一时刻之间的偏移量为第一预设时长或，在第一时刻之后、且与第一时刻之间的偏移量为第一预设时长，从而使得用户设备只需要在第一预设时长上保持一些模块的开启，节省了用户设备的电量。换句话来说，用户设备在检测或测量上述周期信号的时间内，顺带进行了寻呼指示PDCCH的监听。一般来说，如果用户设备检测到寻呼指示PDCCH，并在寻呼指示中发现自己不需要监听寻呼PDCCH，则用户设备可以进入真正睡眠，否则，用户设备需要继续保持一些模块的开启，以便监听寻呼PDCCH。
在一种可能的设计中，监听寻呼指示PDCCH，包括：
在寻呼指示PDCCH监听时机上，监听寻呼指示PDCCH；
其中，寻呼指示PDCCH监听时机满足如下任意一种条件：在第二时刻之前、且与第二时刻之间的偏移量为第二预设时长；第二时刻为寻呼时机的起始时刻或结束时刻，或者寻呼时机对应的寻呼PDCCH监听时机的起始时刻或结束时刻，或者寻呼时机对应的第一个寻呼PDCCH监听时机的起始时刻或结束时刻。
上述时刻可以为符号、时隙等。具体的，本申请中不限定上述时刻的具体取值。 上述第二预设时长可以为1毫秒、2毫秒、1个时隙、2个时隙等。具体的，本申请中不限定第二预设时长的具体取值。在实际应用中，第二预设时长可以由实施本申请中提供的通信方法的通信系统中的高层参数提供，或者可以由用户设备通过其他高层参数推导出。第二预设时长也可以是固定时长。
在现有技术中，寻呼时机表示一组用户设备监听寻呼PDCCH的时间间隔或时间窗口，而基站在一个寻呼时机内可能寻呼的是一个用户设备，但是，其他的用户设备仍然会检测到寻呼PDCCH(检测寻呼PDCCH并且循环冗余校验校验通过，或称成功检测到寻呼PDCCH，或称检测寻呼PDCCH成功)，并继而解码寻呼PDCCH调度的PDSCH承载的寻呼消息，寻呼消息内却并不包含这些其他的用户设备，这些其他的用户设备就会白白浪费了电量。而在本申请中，寻呼指示PDCCH可以在寻呼时机之前，指示后续寻呼时机内真正被寻呼的用户设备子组。或者说，一个寻呼时机对应的用户设备组可以进一步被分成用户设备子组，寻呼指示PDCCH用于指示用户设备子组有没有被寻呼。这样的话，减少了用户设备监听不必要的寻呼PDCCH的可能性，有利于用户设备节能。
需要说明的是，一个寻呼时机对应的用户设备组所分成的一个子组，可以称为一个用户设备子组。一般来说，对应一个寻呼时机或在一个用户设备组内的一个用户设备都会被基站配置一个用户设备子组。基站通过高层参数(高层信令)给该用户设备分配一个用户设备子组。该用户设备子组可能由一个位图(bitmap)内的一个比特表示，或者由一个编号(number)或索引(index)表示。
另一方面，当寻呼指示PDCCH距离寻呼时机或寻呼时机对应的寻呼PDCCH较近时，减少了寻呼指示PDCCH和寻呼PDCCH之间的距离(假设用户设备检测到寻呼指示PDCCH，并在寻呼指示中发现自己需要监听寻呼PDCCH)，用户设备只需要在集中的一段时间内醒来进行寻呼指示PDCCH和寻呼PDCCH的监听即可，用户设备不需要长时间地保持一些模块的开启，节省了用户设备的电量。
S202：若检测到寻呼指示PDCCH，则获取寻呼指示信息。
需要说明的是，寻呼指示PDCCH为基站发送的寻呼指示PDCCH，该寻呼指示PDCCH中包括寻呼指示信息，该寻呼指示信息用于指示用户设备是否需要监听寻呼PDCCH。
一般地，检测到寻呼指示PDCCH是指检测寻呼指示PDCCH并且CRC校验不通过，或称为成功检测到寻呼指示PDCCH，或称为检测寻呼指示PDCCH成功。
另一方面，如果检测不到寻呼指示PDCCH(检测寻呼指示PDCCH但是CRC校验不通过，或称没有成功检测到寻呼指示PDCCH，或称检测寻呼指示PDCCH不成功)，则确定不需要或需要监听寻呼PDCCH。一般来说，选择需要还是不需要可以根据高层参数得出，比如根据系统信息内的参数或配置得出。
与现有技术不同，在现有技术中，寻呼时机针对一组用户设备，用户设备监听的寻呼PDCCH调度的寻呼消息并不包含该用户设备，导致用户设备白白监听了不必要的寻呼PDCCH，进而导致用户设备的耗电量较大。而在本申请中，在根据寻呼指示信息确定需要监听寻呼PDCCH时，减少了监听寻呼PDCCH的可能性，减少了用户设备的对寻呼PDCCH的监听次数，进而节省用户设备的电量。
在一种可能的设计中，获取寻呼指示信息，包括：从寻呼指示PDCCH对应的下行控制信息DCI或下行控制信息DCI格式中的目标比特中获取所述寻呼指示信息。
在另一种可能设计中，获取寻呼指示信息，包括：从寻呼指示PDCCH调度的物理下行共享信道PDSCH中获取寻呼指示信息。
可选地，目标比特可以为DCI或DCI格式中的保留比特。
可选地，目标比特还可以为重定义DCI或DCI格式中已定义的域中的比特。
在一种可能的设计中，寻呼指示信息可以为位图，位图至少包括用户设备对应的用户设备子组对应的比特。
在另一种可能的设计中，寻呼指示信息为用户设备子组的编号或索引。
S203：根据寻呼指示信息，确定是否需要监听寻呼PDCCH。
可选地，当寻呼指示信息为位图时，位图至少包括用户设备对应的用户设备子组对应的比特，可以根据该用户设备对应或所在用户设备子组对应的比特，确定是否需要监听寻呼PDCCH。
例如，若所述比特为1，则确定需要监听所述寻呼PDCCH；若所述比特为0，则确定不需要监听所述寻呼PDCCH。
例如，若所述比特为0，则确定需要监听所述寻呼PDCCH；若所述比特为1，则确定不需要监听所述寻呼PDCCH。
一般来说，该位图可以包括各个用户设备子组对应的比特。该用户设备对应或所在用户设备子组对应该位图内的哪一个比特，这是基站通过高层参数(信令)通知给该用户设备的。例如，该位图为010，三个比特从左到右分别针对三个用户设备子组，而该用户设备对应或所在的用户设备子组为从左到右的第2个子组，那么对应比特为1。
可以选，当寻呼指示信息为用户设备子组的编号或索引时，可以根据用户设备对应或所在用户设备子组的编号或索引是否等于寻呼指示信息内的用户设备子组的编号或索引，确定是否需要监听寻呼PDCCH。
一般来说，用户设备子组的编号或索引也可以称为目标用户设备子组的编号或索引，即所指示的或所寻呼的或所唤醒的用户设备子组的编号或索引。比如寻呼指示信息的二进制数为011，最低位在右，那么编号或索引的十进制数值为3，表示所指示的或所寻呼的或所唤醒的用户设备子组是第3个用户设备子组。
在S203中，由于引入了用户设备子组，减少了监听寻呼PDCCH的可能性，可以节省用户设备的电量。
与现有技术不同，在现有技术中，寻呼时机针对一组用户设备，用户设备监听的寻呼PDCCH调度的寻呼消息并不包含该用户设备，导致用户设备白白监听了不必要的寻呼PDCCH，进而导致用户设备的耗电量较大。而在本申请中，在根据寻呼指示信息确定是否需要监听寻呼PDCCH时，减少了监听寻呼PDCCH的可能性，减少了用户设备的对寻呼PDCCH的监听次数，进而节省用户设备的电量。
本申请提供的通信方法，包括：在寻呼指示PDCCH监听时机上，监听寻呼指示PDCCH；如果检测到寻呼指示PDCCH，则获取寻呼指示信息，并根据寻呼指示信息，确定是否需要监听寻呼PDCCH。在上述方法中，根据寻呼指示信息，确定是否需要监 听寻呼PDCCH，可以减少用户设备对寻呼PDCCH的监听的可能性，进而节省用户设备的电量。
在上述实施例的基础上，下面结合图3对本申请提供的另一种通信方法进行详细说明。具体的，请参见图3实施例。
图3为本申请实施例提供的另一种通信方法的流程示意图。如图3所示，该通信方法包括：
S301：监听寻呼物理下行控制信道PDCCH。
一般来说，寻呼PDCCH用于调度寻呼消息(由PDSCH承载)。
S302：若检测到寻呼PDCCH，则获取寻呼指示信息。
可选地，从寻呼PDCCH对应的下行控制信息DCI或下行控制信息DCI格式中的目标比特中获取寻呼指示信息。其中，目标比特为：DCI或DCI格式中的保留比特。

可选地，寻呼指示信息为位图，位图至少包括用户设备对应的用户设备子组对应的比特。
可选地，寻呼指示信息还可以至少包括用户设备对应的用户设备子组的编号或索引。
一般地，检测到寻呼PDCCH是指检测寻呼PDCCH并且CRC校验不通过，或称为成功检测到寻呼PDCCH，或称为检测寻呼PDCCH成功。
S303：根据寻呼指示信息，确定是否需要接收寻呼PDCCH调度的寻呼消息。
可选地，若寻呼指示信息为位图，可以根据位图中包括用户设备对应的用户设备子组对应的比特，确定是否需要接收寻呼PDCCH调度的寻呼消息。
例如：若比特为1，则确定需要接收寻呼PDCCH调度的寻呼消息；若比特为0，则确定不需要接收寻呼PDCCH调度的寻呼消息。
例如：若比特为0，则确定不需要接收寻呼PDCCH调度的寻呼消息；若比特为1，则确定需要接收寻呼PDCCH调度的寻呼消息。
一般来说，该位图可以包括各个用户设备子组对应的比特。该用户设备对应或所在用户设备子组对应该位图内的哪一个比特，这是基站通过高层参数(信令)通知给该用户设备的。例如，该位图为010，三个比特从左到右分别针对三个用户设备子组，而该用户设备对应或所在的用户设备子组为从左到右的第2个子组，那么对应比特为1。
可选地，若寻呼指示信息至少包括用户设备对应的用户设备子组的编号或索引，则可以根据用户设备所在用户设备子组的编号或索引是否等于寻呼指示信息内的用户设备所在用户设备子组的编号或索引，确定是否需要接收寻呼PDCCH调度的寻呼消息。确定是否需要接收寻呼PDCCH调度的寻呼消息。
例如，用户设备所在用户设备子组的编号(或索引)等于寻呼指示信息内的该用户设备所在的用户设备子组的编号(或索引)，则确定需要接收寻呼PDCCH调度的寻呼消息；若用户设备所在用户设备子组的编号(或索引)不等于寻呼指示信息内的该用户设备所在的用户设备子组的编号(或索引)，则确定不需要接收寻呼PDCCH调度的寻呼消息。
一般来说，用户设备子组的编号或索引也可以称为目标用户设备子组的编号或索引，即所指示的或所寻呼的或所唤醒的用户设备子组的编号或索引。比如寻呼指示信息的二进制数为011，最低位在右，那么编号或索引的十进制数值为3，表示所指示的或所寻呼的或所唤醒的用户设备子组是第3个用户设备子组。
本申请提供的通信方法，包括：监听寻呼PDCCH；若检测到寻呼PDCCH，则获取寻呼指示信息；根据寻呼指示信息，确定是否需要接收寻呼PDCCH调度的寻呼消息。在上述过程中，根据寻呼指示信息，确定是否需要接收寻呼PDCCH调度的寻呼消息，在保障用户设备正确接收到基站发送给其的寻呼消息的情况下，可以避免用户设备接收与其无关的寻呼消息，节省了用户设备的电量。
进一步的，在本申请实施例中，从寻呼PDCCH对应的DCI或DCI格式中的目标比特中获取寻呼指示信息；当寻呼指示信息为位图时，位图包括各个用户设备子组对应的比特；若用户设备所在用户设备子组对应的比特为1(或0)，则确定需要接收寻呼PDCCH调度的寻呼消息；若用户设备所在用户设备子组对应的比特为0(或1)，则确定不需要接收寻呼PDCCH调度的寻呼消息；当寻呼指示信息为用户设备所在用户设备子组的编号或索引时，判断用户设备所在用户设备子组的编号或索引与接收到的用户设备子组的编号或索引是否相同；若是，则确定需要接收寻呼PDCCH调度的寻呼消息；若否，则确定不需要接收寻呼PDCCH调度的寻呼消息。
在上述方法中，由于引入了用户设备子组，从而保障在用户设备正确接收到基站发送给其的寻呼消息的情况下，避免用户设备接收到与其无关的寻呼消息，节省了用户设备的电量。
