如图1所示，终端116与天线112和114通信，其中天线112和114通过前向链路(也称为下行链路)118向终端116发送信息，并通过反向链路(也称为上行链路)120从终端116接收信息。此外，终端122与天线104和106通信，其中天线104和106通过前向链路124向终端122发送信息，并通过反向链路126从终端122接收信息。
例如，在频分双工(Frequency Division Duplex，FDD)系统中，例如，前向链路118可与反向链路120使用不同的频带，前向链路124可与反向链路126使用不同的频带。
再例如，在时分双工(Time Division Duplex，TDD)系统和全双工(Full Duplex)系统中，前向链路118和反向链路120可使用共同频带，前向链路124和反向链路126可使用共同频带。
被设计用于通信的每个天线(或者由多个天线组成的天线组)和/或区域称为网络设备102的扇区。例如，可将天线组设计为与网络设备102覆盖区域的扇区中的终端通信。网络设备可以通过单个天线或多天线发射分集向其对应的扇区内所有的终端发送信号。在网络设备102通过前向链路118和124分别与终端116和122进行通信的过程中，网络设备102的发射天线也可利用波束成形来改善前向链路118和124的信噪比。此外，与网络设备通过单个天线或多天线发射分集向它所有的终端发送信号的方式相比，在网络设备102利用波束成形向相关覆盖区域中随机分散的终端116和122发送信号时，相邻小区中的移动设备会受到较少的干扰。
在给定时间，网络设备102、终端116或终端122可以是无线通信发送装置和/或无线通信接收装置。当发送数据时，无线通信发送装置可对数据进行编码以用于传输。具体地，无线通信发送装置可获取(例如生成、从其它通信装置接收、或在存储器中保存等)要通过信道发送至无线通信接收装置的一定数目的数据比特。这种数据比特可包含在数据的传输块(或多个传输块)中，传输块可被分段以产生多个码块。
此外，该通信系统100可以是PLMN网络、D2D网络、M2M网络、IoT网络或者其他网络，图1只是举例的简化示意图，网络中还可以包括其他网络设备，图1中未予以画出。
图2为举例地可以应用本申请实施例的一种网络架构示意图，该网络架构示意图可以是下一代无线通信系统中的新无线接入(new radio access，NR)的网络架构图。在该网络架构示意图中，网络设备可以被分为一个集中式单元(centralized unit，CU)和多个传输接收点(transmission reception point，TRP)/分布式单元(distributed unit，DU)，即网络设备的基于带宽的单元(bandwidth based unit，BBU)被重构为DU和CU功能实体。需 要说明的是，集中式单元、TRP/DU的形态和数量并不构成对本发明实施例的限定。图2所示的网络设备1和网络设备2各自对应的集中式单元的形态虽然有所不同，但是并不影响各自的功能。可以理解的是，集中式单元1和虚线范围内的TRP/DU是网络设备1的组成元素，集中式单元2和实线范围内的TRP/DU是网络设备2的组成元素，网络设备1和网络设备2为NR系统中涉及的网络设备(或称为基站)。
CU可以处理无线高层协议栈功能，例如无线资源控制(radio resource control，RRC)层，分组数据汇聚层协议(packet data convergence protocol，PDCP)层等，甚至也能够支持部分核心网功能下沉至接入网，术语称作边缘计算网络，能够满足未来通信网络对于新兴业务例如视频，网购，虚拟/增强现实对于网络时延的更高要求。
DU可以主要处理物理层功能和实时性需求较高的层2功能，考虑到无线远端单元(radio remote unit，RRU)与DU的传输资源，部分DU的物理层功能可以上移到RRU，伴随RRU的小型化，甚至更激进的DU可以与RRU进行合并。
CU可以集中式的布放，DU布放取决实际网络环境，核心城区，话务密度较高，站间距较小，机房资源受限的区域，例如高校，大型演出场馆等，DU也可以集中式布放，而话务较稀疏，站间距较大等区域，例如郊县，山区等区域，DU可以采取分布式的布放方式。
图2所举例的S1-C接口，可以为网络设备与核心网之间的标准接口，具体S1-C所连接的设备未在图2中示出。
下面，为了清楚所见，在介绍本申请实施例的通信方法之前，先对本申请实施例提及的术语作以解释。
1、系统信息
如前所述，系统信息(system information，SI)包括最小系统信息(minimum system information，MSI)和其他系统信息(other system information，OSI)。
例如，地震与海啸预警系统(earthquake and tsunami warning systems，ETWS)信息或商业移动告警系统(commercial mobile alert system，CMAS)信息，位于OSI中，当有ETWS/CMAS信息到达后，基站会通过寻呼发送ETWS/CMAS通知，在接收到ETWS/CMAS通知后，具有ETWS/CMAS能力的终端去接收ETWS/CMAS信息；基站也可以通过专用RRC信令直接将ETWS/CMAS信息发送给终端。可以理解的是，ETWS和CMAS都属于警告信息。需要说明的是，对于类似于警告信息，其他紧急信息也可以是类似的处理方式。
又如，与时间相关的信息。例如，协调世界时(Coordinated Universal Time，UTC)信息和全球定位系统时间(Global Positioning System Time，GPS time)信息。UTC和GPS time等与时间相关的信息位于OSI，此信息对于一些终端来说是不要的。
2、公共搜索空间
在NR中，与SI相关的PDCCH公共搜索空间(common search space)类型有：
Type0-PDCCH:用于SIB1的接收，使用SI-RNTI解扰
Type0A-PDCCH:用于OSI的接收，使用SI-RNTI解扰
Type1-PDCCH:用于消息2(message2，MSG-2)，消息4(message4，MSG-4)的接收，使用用于随机接入的无线网络临时标识(random access radio network temporary  identifier，RA-RNTI)，用于临时小区的无线网络临时标识(temporary cell radio network temporary identifier，TC-RNTI)，用于小区的无线网络临时标识(cell radio network temporary identifier，C-RNTI)解扰。
Type2-PDCCH:用于接收寻呼，使用用于寻呼的无线网络临时标识(paging radio network temporary identifier，P-RNTI)解扰。
3、带宽部分
NR频段相较于LTE频段比较宽，按照当前的频谱划分方式，NR的频段至少为100M，而不同终端的射频能力不同，所能支持的最大带宽不同，因此引入带宽部分(bandwidth part，BWP)的概念。图3示出了BWP的一示意图。在一个带宽上为终端分配部分频谱使用，以适应终端所能支持的带宽。且，通过为终端配置多种不同带宽的BWP，以实现对终端的灵活调度以及终端的节能。图4示出了BWP的另一示意图，其中包括同步信号块(Synchronization Signal block，SSB)。
同步信号，包括主同步信号(primary synchronization signal，PSS)和辅同步信号(secondary synchronization signal，SSS)，与物理广播信道(Physical Broadcast Channel，PBCH)可一起组成一个SSB。在一个小区的带宽上会存在一些小区定义的SSB(cell defined SSB)，它们广播SSB，包括PSS，SSS，PBCH，以便终端进行驻留，在广播的PBCH中会携带系统信息中的MIB，并在MIB中指示SIB1的位置。
应理解，本申请实施例对同步信号块的名称并不限定，也就是说，它也可以表述为其他名称。例如，SSB也可以表述为SS/PBCH block。
图4中包括BWP1、BWP2。每个BWP包括初始BWP(initial BWP)。initial BWP是cell defined SSB中广播的MIB指示SIB1所在位置的带宽。在initial BWP上终端可以获取SIB1，以及OSI，并且可以监听寻呼。
每个BWP还包括激活的BWP(active BWP)。终端有业务到达时，基站会将其从initial BWP上调度到一个带宽和其业务相匹配的BWP上，此BWP称为active BWP。根据当前标准，如图4所示，active BWP上可以配置的有Type0A以及Type2类型的PDCCH common search space，也即终端可以在当前active BWP上接收寻呼以及OSI。
接下来结合图5，从交互的角度对本申请实施例的通信方法进行详细说明。方法包括步骤110-120，下面详细描述。
110，确定M个系统信息块，其中，M为正整数；
120，基站向终端发送第一信息，所述第一信息包括所述M个系统信息块，所述M个系统信息块包括以下至少一种：第一系统信息块、警告信息、更新的第二系统信息块，所述第一系统信息块是包括与时间相关的信息的系统信息块。
当发生以下(1)、(2)、(3)任意一种或者多种情况时，基站会向终端发送该第一信息。
(1)基站接收到警告信息。
可以理解的是，警告信息也可以看作是一种系统信息块。或者，基站接收到警告信息，也可以理解为，基站接收到包括警告信息的系统信息块。
其中，警告信息可以包括ETWS信息或CMAS信息等。第一信息包括警告信息，可以理解为，第一信息中包括含有警告信息的系统信息块。例如，基站接收到第三系统信息 块，该第三系统信息块中包括ETWS或CMAS等一些警告信息，基站会将第三系统信息块发送给终端，以使终端获知该警告信息。该警告信息可以是核心网发送给基站的。
(2)基站向终端发送第一系统信息块。
第一系统信息块是包括与时间相关的信息的系统信息块。基站向终端发送第一系统信息块，包括：基站向终端发送与时间相关的信息。
其中，与时间相关的信息包括UTC信息、GPS time信息等。第一信息中包括第一系统信息块，或者，第一信息也可以直接包括与时间相关的信息。例如，基站将UTC信息送给终端，以使终端获知UTC的信息。
(3)基站确定有系统信息块需要更新时。
关于(3)中的系统信息块是除警告信息和第一系统信息块之外的系统信息块。在本申请实施例中，也可以将需要更新的系统信息块称为更新的第二系统信息块。
其中，基站确定有第二系统信息块需要更新时，基站将更新的第二系统信息块发生给终端。第一信息包括更新的第二系统信息块，可以理解为，第一信息包括第二系统信息块，或者，第一信息包括第二系统信息块的更新内容。
可选地，在基站向终端发送第一信息之前，终端向基站发送第二信息，所述第二信息包括与N个系统信息块相关的信息，所述N个系统信息块是订阅的系统信息块，其中，N为整数。
可选地，其中N个系统信息块可以是终端感兴趣或关心的全部或者部分系统信息块。一种可能的方式中，可以是终端在进入连接态后，向基站发送SI订阅信息，使基站获知终端感兴趣的或关心的系统信息块。
SI订阅信息可以包括终端关心的，或者是期望接收到的所有系统信息块。其中SI订阅信息中可以包括终端默认关心的系统信息块；或者，SI订阅信息也可以不包括终端默认关心的系统信息块。
终端默认关心的系统信息块可以包括：MIB和/或SIB1。因为，MIB中包括一些数量有限但最重要也最频繁发生的参数，终端必须使用这些参数来获取其它的系统信息。因此，MIB是终端默认关心的系统信息块。终端向基站发送的SI订阅信息中可以不包括MIB。即便SI订阅信息中不包括MIB，当MIB信息发生改变后，基站也会向终端发送MIB的更新信息。SIB1中包括用来判断某小区是否适合于小区选择的参数，以及其它SIB的时域调度信息。因此，SIB1也是终端默认关心的系统信息块。
终端默认关心的系统信息块还可以包括类似于警告信息、紧急信息等。
需要说明的是，关于ETWS信息、CMAS信息，对于有ETWS信息/CMAS信息能力的终端，也可以将ETWS信息、CMAS信息作为终端默认关心的系统信息，订阅信息中可以不订阅包括ETWS信息、CMAS信息的系统信息块。对于没有ETWS信息/CMAS信息能力的终端，如果是自己感兴趣的或者关心的系统信息，则需要将包括ETWS信息和CMAS信息的系统信息块订阅在订阅信息中。
上述，有ETWS信息/CMAS信息能力的终端指的是，当基站发送ETWS信息或CMAS信息时，终端会默认是自己关心的系统信息，并且会接收，而且有能力处理该信息；没有ETWS信息/CMAS信息能力的终端指的是，当基站发送ETWS信息或CMAS信息时，如果不在终端订阅的信息中，终端是不会去接收的；或者，即使接收，也不能处理该信息。
可选地，SI订阅信息可以不包括终端默认关心的系统信息块，此种情况下，如果默认关心的系统信息块发生更新，或者默认关心的系统信息块中包括第一系统信息块和/或警告信息，基站也会将默认关心的系统信息块以及相关信息发送给终端。
可选地，SI订阅信息中包括N个系统信息块的索引和/或与T个系统信息块相关的能力信息。
一种可能的方式中，SI订阅信息中可以包括N个系统信息块的索引。例如，对于第二系统信息块，可以发送相应的索引的方式使基站获知终端感兴趣的系统信息块，可以使得基站基于该订阅信息发送需要更新的系统信息块。例如，当终端关心SIB2中的系统信息时，该SI订阅信息中包括SIB2的索引，当SIB2中的内容需要更新时，基站将SIB2中需要更新的内容发送至终端。再比如，对于第一系统信息块，以发送相应的索引的方式使基站获知终端对包括与时间相关的信息的系统信息块感兴趣，可以使得基站基于该订阅信息发送第一系统信息块。
具体地，如前所述，终端所需的系统信息绝大多数都是包含在不同SIB中的。换句话说，绝大多数系统信息是以SIB的方式组织的，每个SIB包括与某个功能相关的一系列参数集合。例如，SIB2的内容包括公共或共享信道的信息，SIB13包含多媒体广播多播业务(multimedia broadcast multicast service，MBMS)相关控制信息。如果终端关心的是SIB2中的内容，不关心SIB13中的内容，那么终端可以把SIB2的索引发给基站。当SIB2和SIB13中的内容都需要更新时，基站只需通知终端SIB2中需要更新的内容即可，不需要将SIB13中需要更新的内容发给终端，从而可以避免资源的浪费。
应理解，SIB2、SIB13只是示例性的说明，本申请实施例并未限定于此。
在本申请实施例中，对于更新的第二系统信息块，基站只需将更新的第二系统信息块中，终端所关心的系统信息块发送给终端即可，不需要将更新的第二系统信息块全都发送给终端，这样避免了资源的浪费。
另一种可能的方式中，SI订阅信息中可以包括与T个系统信息块相关的能力信息。
所述与T个系统信息块相关的能力信息包括：终端能够处理所述T个系统信息块。
通过使基站获知终端具有某项能力，可以使得基站基于此能力发送相关的系统信息块。例如，终端能够处理ETWS/CMAS信息。当终端发送ETWS/CMAS信息的能力信息时，如果终端具有ETWS/CMAS信息能力，那么基站在收到ETWS、CMAS信息后，向终端发送该ETWS、CMAS信息；如果终端不具有ETWS/CMAS信息能力，那么基站在收到ETWS、CMAS信息后，为了避免浪费资源，不会向终端发送该ETWS、CMAS信息。
需要说明的是，与T个系统信息块相关的能力信息，是考虑到不同能力的终端对系统信息块具有不同的能力。例如，ETWS/CMAS信息，基站在广播ETWS/CMAS信息时，有ETWS/CMAS信息能力的终端会去接收ETWS/CMAS信息，并有能力处理该信息，没有ETWS/CMAS信息能力的终端不会去接收ETWS/CMAS信息，或即使接收了，也没有能力处理该信息。
可选地，N个系统信息块包括所述第一系统信息块。
第一系统信息块是包括与时间相关的信息的系统信息块。在不同系统中，该第一系统信息块的索引不同，如，在LTE系统中，第一系统信息块的索引是SIB16；在NR中，目前第一系统信息块的索引是SIB9。本申请实施例对此不作限定。应理解，此处第一系统 信息块用来代表与时间相关的系统信息块，并不对本申请实施例的范围构成限制。
其中，关于与时间相关的信息，也可以称为时间信息(time information)。终端利用该时间信息进行多种用途，可能涉及上层，例如，帮助GPS初始化，同步终端的时钟(以确定MBMS会话开始/停止)。
与时间相关的信息，如前所述，可以是UTC信息、GPS time信息，或者其它时间信息。与时间相关的信息可以包括一个绝对时间以及其对应的系统帧号、或时隙、或符号。本申请实施例对此不作限定。
可选地，所述与第一系统信息块相关的信息包括时间精度，所述时间精度与所述第一系统信息块的发送周期相关。
一般情况下，基站会频繁地发送第一系统信息块的信息，然后终端会根据自己的情况去接收第一系统信息块的信息，这样会导致资源的浪费。本申请考虑到不同终端对与时间相关的信息的要求不一样，那么，基站可以按照终端的要求，确定第一系统信息块的发送周期。具体地，在本申请实施例中，终端会根据自己的情况，向基站发送时间精度。基站根据该时间精度就可以确定第一系统信息块的发送周期，进而避免基站频繁地发送第一系统信息块，浪费资源。
其中，确定第一系统信息块的发送周期，也可以理解为，确定发送第一系统信息块的周期。
对于时间精度的表示方式，可以为粒度，单元等方式，本申请实施例对此不作限定。本申请实施例主要是通过终端将时间精度告诉基站，使得基站确定发送第一系统信息块的周期，进而避免基站一直发送与时间相关的信息，浪费资源。时间精度的具体形式，本申请不作限定。例如，如果基站的晶振稳定性是0.05ppm，终端要求的时间精度为1μs，那么基站接收到时间精度(1μs)后就会判断，在1μs/0.05ppm＝20000s之后终端时间就会不准，因此，针对此，基站给终端发送第一系统信息块的周期至少应该为20000s。其中，ppm的单位为百万分之一，μs为微秒。
可选地，基站基于N个系统信息块，向终端发送第一信息。
具体地，N个系统信息块是终端关心的系统信息块，基站基于终端订阅的N个系统信息块，向终端发送第一信息。可以理解为，当终端关心的第二系统信息块需要更新时，基站会将需要更新的系统信息块发送给终端。也可以理解为，如果不是终端所关心的第二系统信息块需要更新，那么，基站不需要向终端发送这些系统信息块的更新信息。或者，当终端关心与时间相关的信息时，终端发送的订阅信息中包括第一系统信息块的信息，那么基站会向终端发送该第一系统信息块的信息。或者，当订阅的N个系统信息块中包括第三系统信息块或警告信息时，基站会将终端发送该第三系统信息块的信息或警告信息。
其中，如前所述，第三系统信息块是包括警告信息的系统信息块。
需要说明的是，当MIB和/或SIB1需要更新时，M个系统信息块中包括MIB和/或SIB1的更新信息。如前所述，当MIB和/或SIB1不在SI订阅信息中时，由于MIB和/或SIB1是终端默认关心的系统信息，在MIB和/或SIB1需要更新时，基站会向终端发送MIB和/或SIB1的更新信息。
需要说明的是，对于有ETWS/CMAS能力的终端，且基站已获知终端具有ETWS或CMAS能力时，ETWS或CMAS等警告信息出现时，基站会向终端发送ETWS或CMAS 等警告信息。
需要说明的是，在本申请实施例中，“N个”和“M个”仅仅为了区分不同的对象，但并不对本申请实施例的范围构成限制；例如，N个系统信息块表示终端关心的一个或多个系统信息块；M个系统信息块表示需要更新或者需要通知终端的系统信息块。例如，M个系统信息块可以包括系统信息块中需要更新的所有系统信息块；和/或，M个系统信息块包括N个系统信息块中需要更新的系统信息块；和/或，M个系统信息块中包括终端关心的系统信息块(如，SIB1、MIB等)中需要更新的系统信息块。本申请实施例并不限定于此。
综上所述，可选地，基站在以下至少四种情况下，会向终端发送第一信息。
情况一
基站基于订阅信息，向终端发送第一信息。
具体地，终端关心的第二系统信息块发生改变时，终端会接收到基站发送的更新的第二系统信息块。其也意味着，如果需要更新的第二系统信息块不是终端所关心的，且不符合下列其它情况，那么基站不需要将需要这些系统信息块发送给终端，从而可以节省资源。或者，当需要更新的第二系统信息块中包括终端所关心的第二系统信息块、还包括终端不关心的第二系统信息块时，那么基站只需要将终端所关心的更新的第二系统信息块发送给终端即可，进而也能够节省资源。
可选地，该第一信息中可以包括N个系统信息块中更新的第二系统信息块的更新信息。
情况二
警告信息到达基站。可选地，ETWS信息和/或CMAS信息到达基站。
ETWS、CMAS等警告信息用于向公众及时发布地震、海啸等紧急信息，指导公众避险和自救。因此，当ETWS、CMAS等警告信息出现时，基站也会向具有此能力的终端发送ETWS、CMAS等警告信息。
作为示例，在LTE系统中，ETWS、CMAS等警告信息都是包括在SIB10～SIB12中的。包含ETWS、CMAS等警告信息的系统信息块虽也是终端所关心的系统信息块，如前所述，对于有ETWS/CMAS能力的终端来说，向基站发送的SI订阅信息中可以不包括包含ETWS、CMAS等警告信息的SIB10～SIB12的索引。因为ETWS、CMAS等警告信息出现时，基站也会将包含ETWS、CMAS等警告信息的系统信息块发送给终端。
应理解，在不同系统中，ETWS、CMAS等警告信息可能包括在不同的SIB中。本申请实施例对ETWS、CMAS等警告信息包括在哪些SIB中不作限定。
情况三
MIB和/或SIB1信息发生改变。可选地，M个系统信息块包括MIB的更新信息和/或SIB1的更新信息。
MIB中包括一些数量有限但最重要也最频繁发生的参数，终端必须使用这些参数来获取其它的系统信息。终端向基站发送的SI订阅信息中可以不包括MIB。MIB信息发生改变后，基站也会向终端发送MIB的更新信息。
SIB1中包括用来判断某小区是否适合于小区选择的参数，以及其它SIB的时域调度信息。终端向基站发送的SI订阅信息可以不包括SIB1。SIB1信息发生改变后，基站也会 向终端发送SIB1的更新信息。
情况四
基站向终端发送第一系统信息块的信息。
M个系统信息块中包括第一系统信息块，第一系统信息块是包括与时间相关的信息的系统信息块。
可选地，基站可以基于终端发送的时间精度，确定第一系统信息块的发送周期。从而可以避免基站频繁地发送第一系统信息块，造成资源的浪费。
应理解，以上列举的情况仅为示例性说明，本申请并未限定于此。例如，情况1、情况2、情况3同时存在。
基站至少在上述四种情况下，向终端发送第一信息，第一信息包括M个系统信息块，M个系统信息块中包括终端关心的第二系统信息块的更新信息和/或第一系统信息块的信息。这样可以避免基站向终端发送的第一信息中包括终端不关心的系统信息块的信息，从而导致资源的浪费。
终端接收到第一信息后，会进行信息处理。例如，当终端接收到第一系统信息块的信息时，会直接应用该第一系统信息块的信息。又如，当终端接收到更新的第二系统信息块时，终端会根据第二系统信息块的信息类型，确定生效时间。又如，当终端接收到警告信息时，会直接应用该警告信息。
一种可能的方式中，终端根据M个系统信息块的生效时间进行处理。其中，M个系统信息块的生效时间表示的是更新和/或应用M个系统信息块的时间。更新可以理解为更新系统信息块中的参数；应用可以理解为收到信息后直接处理该信息，或者，直接应用该信息。一种可能的方式中，当所述第一信息中包括与时间相关的信息时，确定所述与时间相关的信息直接生效。当M个系统信息块中包括ETWS和/或CMAS等警告信息时，终端会直接响应或应用该信息，该信息立即生效；当M个系统信息块中包括更新的第二系统信息块时，生效时间可以是指更新第二系统信息块中的参数的时间。可以理解的是，系统信息块的生效时间可以基于系统信息块的类型确定。本申请实施例中，根据系统信息块的类型确定生效时间，可以使得基站与终端同时更新系统信息块，进而使得基站与终端的系统信息保持一致。
可选的，系统信息块的生效时间可以是协议规定的时间，也可以是基站将生效时间携带于第一信息中，发送给终端。应理解，在本申请实施例中，生效时间可以为立即，也可以为某个绝对时间，也可以为某个帧、某个子帧、某个时隙、某个符号等。本申请实施例对此不作限定。
接下来，具体说明能够使基站与终端保持生效时间一致的两种方式。
方式一
协议规定生效时间，或，协议默认生效时间
可选地，根据所述M个系统信息块的类型确定所述M个系统信息块的生效时间，所述生效时间是更新和/或应用所述M个系统信息块的时间。
基站可以根据系统信息块的类型决定生效时间，终端同样也根据系统信息块的类型决定生效时间，进而使得系统信息保持一致。例如，可以根据系统信息块的索引确定系统信息块的类型。
可选地，当所述第一信息中包括第一类系统信息块时，确定所述第一类系统信息块直接生效，所述第一类系统信息块至少包括以下三种信息中的至少一种：与时间相关的信息、地震与海啸预警系统ETWS的信息和商业移动告警系统CMAS的信息；或，当所述第一信息中包括第二类系统信息块时，确定所述第二类系统信息块的信息在下一个修改周期生效，其中，所述第二类系统信息块包括更新的系统信息块；或，当所述第一信息中包括第二类系统信息块时，确定所述第二类系统信息块的信息在下一个修改周期中所述第二类系统信息块对应的第一次传输时机生效。
第一类系统信息块，表示的是立即生效的系统信息块。例如，与时间相关的信息、ETWS信息或CMAS等警告信息等。对于第一类系统信息块来说，生效时间为立即。与时间相关的信息、ETWS信息或CMAS等警告信息等，只是举例说明，本申请并未限定于此。
第二类系统信息块包括的是更新的系统信息块，例如MIB、SIB1等。更新系统信息块可以理解为更新系统信息块中的参数。
应理解，MIB和SIB1都有相应的发送周期。
OSI中系统信息块通过SI消息发送，一个SI消息跟一个SI窗口(SI-window)相关联，该SI窗口内只能发这个SI消息且可以重复发送多次(发多少次，在哪些子帧上发送等，取决于基站的实现)，但不能发送其它SI消息。SI窗口之间是紧挨着的(如果相邻的话)，既不重叠，也不会有空隙。所有SI消息的SI窗口长度都相同。不同SI消息的周期是相互独立的。
图6是适用于本申请实施例的系统信息块变更周期的示意图。如图6所示，不同的现状代表不同的系统信息块。其中，SIBx、SIBy是泛指除MIB、SIB1之外的系统信息块。从图中可看出，每个系统信息块对应的传输时机可能不同。且，在下一个修改周期(即，下一个变更周期)中，不同的系统信息块传输的时机、次数也不同。例如，对于MIB来说，可能在下一个修改周期中传输9次。图6中还示出了MIB、SIB1、SIBx、SIBy在当前变更周期(current modification period)的下一个修改周期(next modification period)的第一次传输时机。
假如M个系统信息块在下一个修改周期中所述M个系统信息块对应的第一次传输时机生效。具体地，如图6所示，M个系统信息块的生效时间是在下一个修改周期中的第一次传输时机。
需要说明的是，上述具体的系统信息块的生效时间只是示例性说明，本申请并未限定于此，对于终端和基站来说，只要系统信息块的生效时间保持一致即可。例如，除包含ETWS、CMAS等警告信息的系统信息块、包含与时间相关的信息的系统信息块，立即生效外，其余系统信息块的生效时间都是在下一个修改周期的边界生效。例如，生效时间也可以是：ETWS、CMAS等警告信息立即生效；MIB、SIB1信息的生效时间是下一个修改周期的边界生效；其他SIB信息的生效时间可以是在下一个修改周期中对应SI窗口生效。
对于ETWS、CMAS等警告信息，如前所述，ETWS、CMAS等警告信息用于向公众及时发布地震、海啸等紧急信息，指导公众避险和自救。因此，终端接收到ETWS、CMAS等警告信息后，会立即生效。
方式二
基站将生效时间携带于第一信息中。
可选地，所述第一信息还包括所述M个系统信息块的生效时间，所述生效时间是更新和/或应用所述M个系统信息块的时间。
例如，当M个系统信息块中包括MIB、SIB1的更新信息时，即表示上述这些信息需要更新。那么M个系统信息块的更新信息中还包括：MIB和SIB1的生效时间。具体地生效时间可以是下一个修改周期的边界，或者，也可以是在下一个修改周期中MIB和SIB1第一次传输时机生效。
M个系统信息块的生效时间可以相同也可以不同。例如，该M个系统信息块共用一个生效时间；或者，该M个系统信息对应P个生效时间，其中P≤M，P为正整数。本申请实施例对此不限定。
需要说明的是，上述具体的系统信息块的生效时间只是示例性说明，本申请并未限定于此，对于终端和基站来说，只要系统信息块的生效时间保持一致即可。例如，除需要立即生效的系统信息块外，其余终端关心的系统信息块的生效时间都是在下一个修改周期的边界生效。
需要说明的是，上述两种方式只是示例性说明，任何可以使得基站与终端同时更新系统信息块的方式都在本申请实施的范围内。例如，当终端接收到M个系统信息块的信息，并接收到M个系统信息块中部分系统信息块的生效时间，那么对于有生效时间的部分系统信息块，可以根据接收到的生效时间确定这些部分系统信息块的生效时间；对于没有生效时间的系统信息块，可以都默认为立即生效。
在本申请实施例中，也可以通过监听寻呼的方式，接收第一信息。
可选地，从所述基站接收第一信息之前，包括：从所述基站接收指示信息，所述指示信息用于指示在公共搜索空间上监听寻呼消息，所述公共搜索空间能传输所述第一信息；所述从基站接收第一信息，包括：监听所述寻呼消息，并在所述公共搜索空间上从所述基站接收第一信息。
可选地，所述公共搜索空间位于公共带宽部分BWP上，所述公共BWP能传输所述第一信息，所述公共BWP位于至少两个BWP重叠的位置，所述两个BWP供两个终端使用。
在本申请实施例中，系统信息块更新后，基站可以通过广播的形式通知终端。具体地，公共搜索空间对于不同的终端是不同的，针对不同的终端会单独配置公共搜索空间。如果单独为终端配置公共搜索空间，终端会直接监听寻呼。如果没有为终端单独配置公共搜索空间，但是有公共的公共搜索空间供多个终端使用，即，如果终端当前工作的active BWP上包含任何可以广播系统信息的公共搜索空间时，基站向终端发送指示信息，指示终端在该公共搜索空间上监听第一信息。基站向终端发送的第一信息通过广播的形式发送至终端。
在本申请实施例中，提出了虚拟BWP(即，公共BWP的一例)。接下来结合图7具体描述。
基站确定公共BWP，所述公共BWP位于至少两个BWP重叠的位置，所述两个BWP供两个终端使用；所述基站通过所述公共BWP向所述至少两个终端中的至少一个终端发送寻呼信息和/或系统信息。
基站为终端在active BWP上配置公共搜索空间，那么终端就可通过监听此公共搜索 空间来或获取寻呼消息或者系统信息。BWP是根据终端单独配置的(UE specific)，不同终端的BWP很有可能是重叠的。如果不同终端的BWP有重叠，却为每个终端单独配置公共搜索空间以及终端所调度的PDSCH资源，这样会造成资源的浪费。因此，本申请实施例提供一种方案，当基站为不同终端在各自的BWP上配置公共搜索空间的时候，如果这两个BWP是有重叠部分的，就将此公共搜索空间以及它对应的PDSCH资源配置在重叠的部分。
具体地，基站为BWP重叠的终端在重叠的位置配置虚拟BWP来广播寻呼以及系统信息，该虚拟BWP是不同于正常active BWP的一种BWP，在配置时需要特定编号。图7示出了虚拟BWP的示意图。
如图7所示，对于终端1，至少分配有BWP1、BWP2、BWP3、BWP4；对于终端2，至少分配有BWP1、BWP2、BWP3、BWP4。终端1的BWP和终端2的BWP具有重叠部分，因此，可选地，重叠的部分配置有虚拟BWP1(Virtual BWP1)、虚拟BWP2、虚拟BWP3。其中，虚拟BWP1可以包含有终端1的BWP1、BWP2、BWP4，还包含有终端2的虚拟BWP1。虚拟BWP2可以仅包含有终端2的BWP2。虚拟BWP3包含有终端1的BWP3和BWP4，还包含有终端2的BWP3和BWP4。
可选地，所述公共BWP的配置参数至少包括：标识、频域资源、带宽、子载波间隔。
基站为虚拟BWP配置标识，例如，虚拟BWP1、虚拟BWP2、虚拟BWP3。每个虚拟BWP上配有频域资源、带宽、子载波间隔。
应理解，上述虚拟BWP1、虚拟BWP2、虚拟BWP3、以及终端1和终端2只是示例性说明，本申请并未限定于此，任何可以将多个终端重叠部分配置虚拟BWP的方式都包含在本申请实施例的范围内。例如，虚拟BWP1可以包含有终端1的BWP1、BWP4，还包含有终端2的虚拟BWP1。虚拟BWP2可以包含有终端1和终端2的BWP2。
终端1和/或终端2根据虚拟BWP的配置去监听寻呼消息，当寻呼消息指示系统信息更改或者ETWS/CMAS通知后，在此虚拟BWP上接收系统信息。
本申请实施例，通过在重叠资源上部署公用的公共搜索空间，可以降低资源消耗，提高资源利用率。
可选地，所述第一信息承载于RRC信令。
该RRC信令可以是广播的形式，也可以是专用RRC的形式。当第一信息承载于专用RRC信令上时，可以实现终端获取系统信息块的信息，进而节省寻呼开销。当第一信息中包括第一系统信息块的信息，并承载于广播信道上时，可以通过寻呼的方式通知终端与时间相关的信息。
当M个系统信息块需要更新时，基站可以通过专用RRC信令将需要更新的M个系统信息块的更新信息发送至终端。具体地，如果当前终端在initial BWP上，终端可以正常接收广播来获取发生改变的系统信息块。如果当前终端不在初始BWP上，基站通过专用RRC信令给终端发送消息，该消息包含更新的系统信息块的内容，可选地，还可以包括更新的系统信息块的生效时间。
通过专用RRC信令，可以实现终端在active BWP上获取系统信息块。如果当前终端在active BWP上，基站不需要在active BWP上发送寻呼消息，进而节省寻呼开销。
可选地，所述从基站接收第一信息之前，包括：检测寻呼消息，所述寻呼消息中携带 所述与时间相关的信息的通知信息。
具体地，当第一信息中包括第一系统信息块时，基站可以基于第一系统信息块的发送周期发送第一系统信息块。当基站采用广播的形式发送第一系统信息块时，终端可以先监听寻呼消息，监听有没有第一系统信息块的通知信息，如果监听到，再去读。避免资源的浪费。
下面结合图8以一个具体实施例为例，描述通过专用RRC信令的方式通知终端系统信息块需要更新的实施方式。应理解，除以下描述外，下述实施例还可以参考前述各实施例中的相关描述，以下为了简洁，不再赘述。
210，终端进入连接状态。
220，终端向基站发送SI订阅信息。
该SI订阅信息中包括终端关心的系统信息块。
可选地，该SI订阅信息中包括N个系统信息块的索引和/或与T个系统信息块相关的能力信息，其中，T为小于或等于N的正整数。
通过将终端关心的系统信息块发送至基站，以便基站在终端关心的第二系统信息块需要更新时通知终端，对于终端不关心的第二系统信息块需要更新时，不需要通知终端。
此外，终端将与系统信息块相关的能力信息发送给基站，可以使得基站根据终端的能力发送系统信息，进而避免浪费资源。
关于SI订阅信息同方法100中的相似，为了简洁，此处不再赘述。
230，终端关心的系统信息块需要更新，或者，发现ETWS/CMAS信息。
如果终端是具有ETWS/CMAS信息的能力，当终端关心的系统信息块需要更新时，或者，发现ETWS/CMAS等警告信息时，基站会将收到的信息或是更新的系统信息块发送至终端。
240，基站向终端发送专用RRC信令，该信令中携带需要更新的、终端关心的系统信息块。
基站可以通过RRC信令来发送需要更新的系统信息块。这种方法是处于active BWP上的连接态终端的数目较少时，尤其有效，其实现简单，对现有协议改动较小，且基站不需要在active BWP上发送寻呼消息，可以节省寻呼开销。
需要更新的系统信息块的具体生效时间如上述方法中所述，此处不再赘述。
应理解，本申请实施例中的具体的例子只是为了帮助本领域技术人员更好地理解本申请实施例，而非限制本申请实施例的范围。
应理解，在本申请的各种实施例中，上述各过程的序号的大小并不意味着执行顺序的先后，各过程的执行顺序应以其功能和内在逻辑确定，而不应对本申请实施例的实施过程构成任何限定。
本申请实施例，通过基站获知终端关心的系统信息块，使得在系统信息块需要更新或者是收到警告信息时，只需将终端关心的系统信息块发送至终端即可，对于终端不关心的系统信息，不需要发送至终端，从而能够避免资源的浪费。
另外，本申请实施例，通过使得基站和终端更新系统信息块的时间保持一致，例如，可以是基于协议确定生效时间，或基站将需要更新的系统信息的生效时间也发送至终端，从而使得基站和终端的系统信息保持同步。
可以理解的是，上述各个方法实施例中，由终端实现的方法和操作，也可以由可用于终端的部件(例如芯片或者电路)实现，由基站实现的方法和操作，也可以由可用于基站的部件(例如芯片或者电路)实现。
