本公开基于申请号为202211210675.X、申请日为2022年09月30日的中国专利申请提出，并要求该中国专利申请的优先权，该中国专利申请的全部内容在此以引入方式并入本公开。
技术领域
本公开涉及通信技术领域，具体涉及一种传输指示方法、装置、通信设备和存储介质。
背景技术
基站节能作为节省运营商开支，实现无线通信领域低碳高效的手段之一，获得了运营商、设备商的一致支持。从时域角度来看，由于存在周期性广播信号，如同步信号块(SSB)、系统信息及其调度信息，这些符号无法实现基站的睡眠，在增强技术的研究中将会考虑如何进行此类信号的传输优化，增加基站的睡眠时间。如增大SSB及系统信息块(SIB，System Information Block)的传输周期，从而增加基站可进入睡眠的时隙个数、符号个数，节省基站能耗。
在单载波的场景下，由于终端只能通过单个的载波实现初始接入，当SSB和系统信息的传输周期增大以后，此时终端并不知道在哪个SSB传输时机上会有SSB发送，因此会在每个传输时机上尝试去检测，对于终端来说，能耗较高。因此，在上述场景下，如何识别系统信息的周期，目前尚无有效解决方案。

本公开实施例提供了一种传输指示方法。图1为本公开实施例的传输指示方法的流程示意图一；如图1所示，所述方法包括：
步骤101：网络设备发送包含同步信号的下行信号；其中，所述下行信号用于确定以下至少之一：
PBCH的传输时机或者传输周期；
类型0-PDCCH的传输时机或者传输周期；
系统信息的传输时机或者传输周期。
本实施例中，所述网络设备发送包含同步信号的下行信号，可以认为是网络设备发送下行信号或第一信号，所述下行信号或第一信号中包含同步信号。以同步信号中包括PSS为例，则网络设备发送包含PSS的下行信号，或者网络设备发送下行信号或第一信号，所述下行信号或第一信号中包括PSS。
本实施例中，作为一种示例，同步信号可包括多种类型，不同类型的同步信号的传输特性可能不同，例如不同类型的同步信号的传输样式(pattern)或传输周期不同，则网络设备可通过不同类型的同步信号的传输特性对PBCH的传输时机或者传输周期、类型0-PDCCH(type0-PDCCH)的传输时机或者传输周期、系统信息的传输时机或者传输周期等进行指示。 其中，需要说明的是，在下行信号用于指示PBCH的传输时机或者传输周期的情况下，下行信号中包括的同步信号不包括PBCH，即可通过除PBCH以外的其他类型的同步信号的传输特性对PBCH的传输时机或者传输周期进行指示。
在一些可选实施例中，所述网络设备发送包含同步信号的下行信号，包括以下至少之一：
所述网络设备以第一周期在至少一个第一传输时机发送包含PSS的下行信号；

可选地，所述下行信号用于确定PBCH的传输时机或者传输周期；其中，所述PBCH以第三周期在第三传输时机上与PSS和SSS共同发送；所述第二周期为所述第一周期的N倍，N为大于或等于1的正整数，所述第三周期为所述第二周期的M倍，M为大于或等于1的正整数。
常规技术方案中，同步信号块(SSB)包括PSS、SSS和PBCH。通常情况下，SSB的传输周期为20毫秒(ms)。而通过增大同步信号的传输周期，从而增加基站可进入睡眠的时隙个数、符号个数等等，以达到节省基站能耗的作用。因此本实施例中，通过增大同步信号的周期，进而达到可达到上述效果。另外，通过不同类型的同步信号的传输周期不同，从而实现对PBCH的传输时机或者传输周期、类型0-PDCCH的传输时机或者传输周期、系统信息的传输时机或者传输周期等进行指示。
除了传输周期，SSB在每个周期内具有一定的时域分布，同一个周期内的所有SSB位置均会限制在5ms内。这种结构可确保终端可以在5ms内完成对所有SSB的测量，而无须在一个周期内多次打开测量窗口，有利于终端测量和节省功耗。同时，在5G NR中，对于宏站覆盖场景，基站通 常需要配置半静态帧结构。在半静态帧结构下，下行资源通常被配置在下上行转换周期的前半部，将周期内的SSB集中放置在5ms内有利于将SSB放置在半静态帧结构所配置的下行资源中。参照图2所示，为低频段5ms窗内包含SSB的时隙分布示意图，其中非空白部分代表有SSB发送的时隙。
SSB在一个5ms时间窗内的具体时域分布位置与SSB子载波间隔及频段有关。目前协议中给出了实例A(Case A)、实例B(Case B)、实例C(Case C)、实例D(Case D)、实例E(Case E)五种SSB的排布方式，其中Case A/B/C针对6GHz以下频段，Case D/E针对高频毫米波。各种排布方式下SSB的具体位置如下：
1.实例A(Case A)：针对15kHz SSB子载波间隔的场景。SSB的第一个符号的位置序号为{2,8}+14*n。对于对应Lmax＝4的频段，n＝0,1，即仅占据2个时隙(slot)；对于对应Lmax＝8的频段，n＝0,1,2,3，需占据4个时隙。图3a给出了SSB子载波间隔采用15kHz且Lmax＝4时，SSB在5ms窗内的位置。
2.实例B(Case B)：针对30kHz SSB子载波间隔。SSB的第一个符号位置序号为{4,8,16,20}+28*n。对于对应Lmax＝4的频段，n＝0；对于对应Lmax＝8的频段，n＝0,1。图3b给出了SSB子载波间隔采用30kHz且Lmax＝8时，Case B SSB在5ms窗内的位置。
3.实例C(Case C)：针对30kHz子载波间隔。SSB的第一个符号位置序号为{2,8}+14*n。对于对应Lmax＝4的频段，n＝0,1；对于对应Lmax＝8的频段，n＝0,1,2,3。图3b给出了采用30kHz SSB子载波间隔且Lmax＝8时，Case C SSB在5ms窗内的位置。
4.实例D(Case D)：针对SSB子载波间隔为120kHz的场景。SSB的第一个符号位置为{4,8,16,20}+28*n，对于6GHz以上的高频段(Lmax＝64)，n＝0,1,2,3,5,6,7,8,10,11,12,13,15,16,17,18。
5.实例E(Case E)：针对SSB子载波间隔为240kHz的场景，SSB的第一个符号位置为{8,12,16,20,32,36,40,44}+56*n，对于6GHz以上的高频段，n＝0,1,2,3,5,6,7,8。
值得注意的是，对于6GHz以下频段采用30kHz SSB子载波间隔时，SSB存在两种摆放方式：Case B、Case C(如3b所示)。
这里可以看到每个SSB会有确定的起始符号位置，从起始符号开始连续传输4个符号，承载SSB，这里将每个4符号的SSB的传输机会，称为一个传输时机。可以看到一个传输时机可以包含多个符号，位于一个时隙内。这些排布方式实际上给出了在一个周期内的不同SSB索引的传输时机。对于同一个SSB索引来说，它会按照SSB的周期，比如20ms(或其他值)在其对应的传输时机上重复传输。
本实施例中，下行信号中包括的同步信号包括PSS，和/或，包括PSS和SSS；其中，以第一周期在至少一个第一传输时机仅发送PSS，以第二周期在第二传输时机共同发送PSS和SSS，也就是说，PSS的传输周期和SSS的传输周期不同，并且在发送SSS的同时共同发送PSS。参照图4所示，图4中的(a)示出的是常规技术方案中SSB的传输，传输周期为20ms。图4中的(b)示出本实施例中下行信号的传输，本示例中，PSS依然按照传统的20ms的传输周期进行传输，但SSS的传输周期为40ms，即N等于2，也即每隔一个PSS，才会出现SSS与PSS伴随传输。当然上述仅为示例，在其他实施例中，N也可为其他取值，本实施例中对此不做限定。
本实施例中，PBCH仅会与PSS和SSS共同传输，因此只有在PSS和SSS共同传输的传输时机，才有可能传输PBCH。参照图4所示，PBCH的传输周期为80ms，即M等于2，也即每隔一次PSS和SSS共同传输的传输时机，才会出现PBCH与PSS和SSS伴随传输。当然上述仅为示例，在其他实施例中，M也可为其他取值，本实施例中对此不做限定。其中，所述 PBCH与PSS和SSS共同发送，具体可以是指在SSB的传输时机(如第三传输时机)上同时发送PBCH、PSS和SSS，也即在SSB的传输时机(如第三传输时机)所对应的连续4个符号上同时发送PBCH、PSS和SSS。
对于终端的检测来说，终端会在同步栅格上先检测PSS，终端解码PSS信号，获得部分小区取值为{0,1,2}。在解调PSS后，终端将继续尝试解码SSS，SSS有336个取值，对应336个由两个127长的m序列模二加后得到的Gold序列，从而获得部分小区取值范围为{0,1，…335}；最终根据公式得到完整小区ID。之后再解调PBCH，获得必要的小区信息等。
本实施例中，终端检测到PSS之后，在相同的传输时机(occasion)上有可能检测到SSS，也有可能没有检测到SSS，则终端可以基于此判断，后续PBCH的检测只需要在PSS和SSS同时出现的时刻检测。参照图4中所示，例如，UE1在某传输时机搜索PSS，获取到PSS之后，并未获取到SSS，则UE1就会到下一个传输时机(20ms的传输周期)去获取SSS，并尝试检测PBCH，检测到PSS和SSS之后，并未获取到PBCH，则UE只会继续以每隔40ms间隔尝试获取PBCH，而不会在只有PSS的传输时机上检测，从而节省终端能耗。又例如，对于UE2，在某传输时机上同时检测到PSS和SSS，但没有检测到PBCH，则终端会跳过下一个检测时机，间隔一个时机去检测PBCH，从而实现了终端节能；或者会在下一个检测时机进行检测，可能只检测到PSS，进一步在下一个检测时机进行检测，检测到PBCH，并同时检测到PSS和SSS，从而明确了PSS和SSS的传输周期为40ms。
在一些可选实施例中，所述PBCH用于指示类型0-PDCCH的传输时机和/或系统信息的传输时机。
本实施例中，在检测到PBCH的传输时机对应类型0-PDCCH(type0-PDCCH)搜索空间去检测type0-PDCCH，也即PBCH的传输时机 是与type0-PDCCH的传输时机或传输周期相关联的或对应的，即本实施例中包含同步信号的下行信号能够隐含指示type0-PDCCH。而type0-PDCCH是用于调度系统信息的，也即本实施例中包含同步信号的下行信号还能够隐含指示系统信息的传输时机或者传输周期。其中，示例性的，系统消息可以是系统信息块(SIB，System Information Block)，如SIB1。
在本公开的一些可选实施例中，所述下行信号包含以第四周期共同发送的PSS、SSS和PBCH，所述下行信号中的PBCH用于指示以下至少之一：
类型0-PDCCH的传输时机或者传输周期；
系统信息的传输时机或者传输周期。
本实施例中，所述第四周期可以是常规技术方案中SSB的传输周期，例如20ms。则本实施例中是指采用常规的20ms传输周期传输包含有PSS、SSS和PBCH的下行信号，也即传输SSB。本实施例中，可通过PBCH中的比特指示以下至少之一：类型0-PDCCH的传输时机或者传输周期；系统信息的传输时机或者传输周期。示例性的，通过PBCH中的有限比特指示类型0-PDCCH和/或系统信息的传输周期，常规的传输周期是20ms，类型0-PDCCH和/或系统信息的传输周期可以是40ms、80ms、160ms等等，则需要2比特进行指示。当然，类型0-PDCCH和/或系统信息的传输周期不限于上述示例，还可以是其他取值，本实施例中对此不做限定。
其中，所述共同发送的PSS、SSS和PBCH，具体可以是指在SSB的传输时机上同时发送PBCH、PSS和SSS，也即在SSB的传输时机所对应的连续4个符号上同时发送PBCH、PSS和SSS。
在一些可选实施例中，所述PBCH中的MIB信息的预留比特和/或PBCH中与时隙相关的比特用于指示以下至少之一：
类型0-PDCCH的传输时机或者传输周期；
系统信息的传输时机或者传输周期。
PBCH信道中，携带高层24比特(bit)的信息和物理层的8比特的信息，其中，高层24比特中具有1个预留比特。上述PBCH中的MIB信息的预留比特即为高层的预留比特。物理层的8比特中，4比特为系统帧号的四位最低位比特(LSB)，2比特为系统半帧指示，3比特为SSB索引(SSB index)的三位最高位比特(MSB)。对于最大波束个数Lmax＝64的情况，该信息指示SSB index的3位MSB。对于6GHz以下频段，最大只支持8波束，SSB index已经完全通过PBCH的解调参考信号(DMRS，Demodulation Reference Signal)确定，因此，在6GHz以下的低频中，使用了这3bit中的其中1bit，与ssb-SubcarrierOffset字段联合指示SSB与SIB1控制信道之间子载波级别的偏移，其他2bit则为预留信息；则上述PBCH中与时隙相关的比特即为上述场景下的物理层的比特。也即，PBCH中携带了高层的MIB信息，还会产生8比特时序相关的比特(timing related PBCH payload bits)，可以使用MIB中的1个预留比特和/或与时隙相关的比特(8比特)中的最后两位在L不等于64时作为预留的两比特指示类型0-PDCCH和/或SIB1的传输周期或传输时机。例如00表示默认20ms周期，01表示40ms，10表示80ms，11表示160ms等等。指示传输时机包括指示以多少周期的间隔在周期内传输，或者说指示传输时间出现的间隔，或出现的时隙位置等。
在本公开的一些可选实施例中，所述方法还包括：所述网络设备基于所述系统信息的传输时机或者传输周期发送系统信息，和/或，基于类型0-PDCCH的传输时机或者传输周期发送所述类型0-PDCCH。
可选地，用于传输所述系统信息的无线帧的帧标识与所述系统信息的传输周期满足约定关系，和/或，用于传输类型0-PDCCH的无线帧的帧标识与类型0-PDCCH的传输周期满足约定关系。
本实施例中，若通过PBCH指示系统信息或传输类型0-PDCCH(也即 调度系统信息的控制信道)的传输周期，则还需要确定传输周期内的传输时机。例如系统信息以Prep＝80ms周期进行传输，则每隔4个SSB的传输时机会出现一个系统信息的传输时机，则系统信息出现在4个传输时机中的哪一个需要提前约定。本实施例中，示例性的，可以约定SFN*10 mod Prep＝0，或者SFN mod(Prep/10)＝0的无线帧作为传输系统信息的传输时机；如果Prep的单位为10ms的情况下，约定SFN mod Prep＝0的无线帧作为传输系统信息的传输时机；其中，SFN表示系统帧号(System Frame Number)，每隔SFN对应的帧定时为10ms，Prep表示系统信息的传输周期。这样，终端在接收完PBCH能够获得帧定时10ms，根据PBCH中的2比特指示，能够知道当前系统信息(如SIB1)传输的传输周期，根据约定关系确定系统信息(如SIB1)的传输时机，只在这些传输时机上进行系统信息(如SIB1)的检测。当然，还可采用其他约定关系确定传输时机，本实施例中对此不做限定。类似的，类型0-PDCCH的传输时机的确定方式参照系统信息的传输时机的确定方式，这里不再赘述。
示例性的，参照图5所示，按照20ms的传输周期传输SSB。UE1检测到PBCH，获得帧定时10ms，通过PBCH中的比特指示可确定SIB1的传输周期为80ms，则可根据约定关系确定SIB1的传输时机，进而在对应的传输时机读取SIB1以及调度PDCCH(即type0-PDCCH)。其中，调度PDCCH(即type0-PDCCH)是用于调度SIB的，也即通过读取调度PDCCH(即type0-PDCCH)实现对SIB的读取。
在本公开的一些可选实施例中，所述方法还包括：所述网络设备接收终端发送的第一信号，所述第一信号用于请求或触发网络设备以第四周期发送系统信息和/或类型0-PDCCH；所述网络设备以第四周期在第四传输时机发送系统信息和/或类型0-PDCCH。
本实施例中，在采用上述PBCH指示类型0-PDCCH的传输时机或者传 输周期和/或系统信息的传输时机或者传输周期的情况下，类型0-PDCCH的传输周期和/或系统信息的传输周期可能较长，大于常规的20ms。若终端对时延要求较高，则终端还可以主动发起请求，请求或触发网络设备以第四周期(20ms)发送系统信息。其中，所述第一信号例如可以使用物理随机接入信道(PRACH，Physical Random Access Channel)类似的前导码(preamble)，即终端通过发送前导码请求或触发网络设备以第四周期发送系统信息和/或类型0-PDCCH。进一步地，网络设备接收到第一信号后，以第四周期(20ms)在第四传输时机发送系统信息和/或类型0-PDCCH。
参照图6所示，UE检测到SSB中的PBCH，获得帧定时10ms，通过PBCH中的比特指示可确定SIB1或类型0-PDCCH的传输周期为80ms，则可根据约定关系确定SIB1或类型0-PDCCH的传输时机，进而在对应的传输时机读取SIB1以及调度PDCCH(即type0-PDCCH)。UE可发送第一信号，请求提前获得SIB1。这里的提前是指，原来按照80ms传输的SIB1或类型0-PDCCH，在基站接收到第一信号后，基站回到按照传统的20ms(或其他约定的周期)的周期在下一个20ms周期对应的SSB所确定的时频资源位置发送SIB1及其调度PDCCH的信息。按照现有流程SSB中的PBCH中的pdcch-ConfigSIB1——8bit，用来指示用于调度SIB1消息的控制资源集合(CORESET)的时频资源位置，以及相应的type0-PDCCH搜索空间的参数；因此，当SSB按照20ms周期传输时，其对应的PBCH指示的用于调度SIB1消息的控制信息的周期也会由较大的周期恢复到20ms，type0-PDCCH及其对应的CORESET的信息通过PBCH指示，确定检测的时频资源位置，进而通过type0-PDCCH搜索空间中检测到的PDCCH，确定检测SIB1的时频位置，获得SIB1。而在按照80ms传输的SIB1或类型0-PDCCH时，并不是每个PBCH后面都会在相同周期伴随着SIB1或类型0-PDCCH。UE在下一个SSB的传输时机接收SIB1以及调度PDCCH，获 取到随机接入信息，发起随机接入流程。
在一些可选实施例中，所述网络设备接收终端发送的第一信号，包括：所述网络设备在发送所述同步信号的第五传输时机所处的无线帧的最后一个子帧接收所述第一信号。
本实施例中，由于帧结构周期10ms必然重复一次，因此可以在接收SSB的时机所处的无线帧的最后一个子帧来传输。
基于上述实施例，本公开实施例还提供了一种传输指示方法。图7为本公开实施例的传输指示方法的流程示意图二；如图7所示，所述方法包括：
步骤201：终端接收包含同步信号的下行信号；基于所述下行信号确定以下至少之一：PBCH的传输时机或者传输周期；类型0-PDCCH的传输时机或者传输周期；系统信息的传输时机或者传输周期。
本实施例中，作为一种示例，同步信号可包括多种类型，不同类型的同步信号的传输特性可能不同，例如不同类型的同步信号的传输样式(pattern)或传输周期不同，则网络设备可通过不同类型的同步信号的传输特性对PBCH的传输时机或者传输周期、类型0-PDCCH的传输时机或者传输周期、系统信息的传输时机或者传输周期等进行指示。其中，需要说明的是，在下行信号用于确定PBCH的传输时机或者传输周期的情况下，下行信号中包括的同步信号不包括PBCH，即可通过除PBCH以外的其他类型的同步信号的传输特性对PBCH的传输时机或者传输周期进行指示。则终端可根据接收到的下行信号中的同步信号的类型及其传输特性确定以下至少之一：PBCH的传输时机或者传输周期；类型0-PDCCH的传输时机或者传输周期；系统信息的传输时机或者传输周期。
在一些可选实施例中，所述终端接收包含同步信号的下行信号，包括以下至少之一：
所述终端以第一周期在至少一个第一传输时机接收包含PSS的下行信号；
所述终端以第二周期在第二传输时机接收包含PSS和SSS的下行信号。
可选地，其中，所述PBCH以第三周期在第三传输时机上与PSS和SSS共同发送；所述第二周期为所述第一周期的N倍，N为大于或等于1的正整数，所述第三周期为所述第二周期的M倍，M为大于或等于1的正整数。
本实施例中，下行信号中包括的同步信号包括PSS，和/或，包括PSS和SSS；其中，以第一周期在至少一个第一传输时机仅发送PSS，以第二周期在第二传输时机共同发送PSS和SSS，也就是说，PSS的传输周期和SSS的传输周期不同，并且在发送SSS的同时共同发送PSS。
本实施例中，PBCH仅会与PSS和SSS共同传输，因此只有在PSS和SSS共同传输的传输时机，才有可能传输PBCH。因此终端检测到PSS之后，在相同的传输时机(occasion)上有可能检测到SSS，也有可能没有检测到SSS，则终端可以基于此判断，后续PBCH的检测只需要在PSS和SSS同时出现的时刻检测，从而确定PBCH的传输周期或传输时机。参照图4中所示，例如，UE1在某传输时机搜索PSS，获取到PSS之后，并未获取到SSS，则UE1就会到下一个传输时机(20ms的传输周期)去获取SSS，并尝试检测PBCH，检测到PSS和SSS之后，并未获取到PBCH，则UE只会继续以每隔40ms(即间隔第二周期)间隔尝试获取PBCH，而不会在只有PSS的传输时机上检测，从而节省终端能耗。又例如，对于UE2，在某传输时机上同时检测到PSS和SSS，但没有检测到PBCH，则终端会跳过下一个检测时机，间隔一个时机去检测PBCH，从而实现了终端节能；或者会在下一个检测时机进行检测，可能只检测到PSS，进一步在下一个检测时机进行检测，检测到PBCH，并同时检测到PSS和SSS，从而明确了PSS和SSS的传输周期为40ms。
在一些可选实施例中，所述PBCH用于指示类型0-PDCCH的传输时机和/或系统信息的传输时机。
本实施例中，在检测到PBCH的传输时机对应类型0-PDCCH(type0-PDCCH)搜索空间去检测type0-PDCCH，也即PBCH的传输时机是与type0-PDCCH的传输时机或传输周期相关联的或对应的，即本实施例中包含同步信号的下行信号能够隐含指示type0-PDCCH。而type0-PDCCH是用于调度系统信息的，也即本实施例中包含同步信号的下行信号还能够隐含指示系统信息的传输时机或者传输周期。其中，示例性的，系统消息可以是系统信息块(SIB，System Information Block)，如SIB1。
在本公开的一些可选实施例中，所述下行信号包括以第四周期共同发送的PSS、SSS和PBCH，所述下行信号中的PBCH用于指示以下至少之一：

本实施例中，所述第四周期可以是常规技术方案中SSB的传输周期，例如20ms。则本实施例中是指采用常规的20ms传输周期传输包含有PSS、SSS和PBCH的下行信号，也即传输SSB。本实施例中，可通过PBCH中的比特指示以下至少之一：类型0-PDCCH的传输时机或者传输周期；系统信息的传输时机或者传输周期。示例性的，通过PBCH中的有限比特指示类型0-PDCCH和/或系统信息的传输周期，常规的传输周期是20ms，类型0-PDCCH和/或系统信息的传输周期可以是40ms、80ms、160ms等等，则需要2比特进行指示。当然，类型0-PDCCH和/或系统信息的传输周期不限于上述示例，还可以是其他取值，本实施例中对此不做限定。
在一些可选实施例中，所述PBCH中的MIB信息的预留比特和/或PBCH中与时隙相关的比特用于指示以下至少之一：
类型0-PDCCH的传输时机或者传输周期；
系统信息的传输时机或者传输周期。
在本公开的一些可选实施例中，所述方法还包括：所述终端基于所述系统信息的传输时机或者传输周期接收系统信息，和/或，基于所述类型0-PDCCH的传输时机或者传输周期接收类型0-PDCCH。
可选地，用于传输所述系统信息的无线帧的帧标识与所述系统信息的传输周期满足约定关系，和/或，用于传输类型0-PDCCH的无线帧的帧标识与类型0-PDCCH的传输周期满足约定关系。
本实施例中，若通过PBCH指示系统信息或传输类型0-PDCCH(也即调度系统信息的控制信道)的传输周期，则还需要确定传输周期内的传输时机。例如系统信息以Prep＝80ms周期进行传输，则每隔4个SSB的传输时机会出现一个系统信息的传输时机，则系统信息出现在4个传输时机中的哪一个需要提前约定。本实施例中，示例性的，可以约定SFN*10 mod Prep＝0，或者SFN mod(Prep/10)＝0的无线帧作为传输系统信息的传输时机；如果Prep的单位为10ms的情况下，约定SFN mod Prep＝0的无线帧作为传输系统信息的传输时机；其中，SFN表示系统帧号(System Frame Number)，每隔SFN对应的帧定时为10ms，Prep表示系统信息的传输周期。这样，终端户在接收完PBCH能够获得帧定时10ms，根据PBCH中的2比特指示，能够知道当前系统信息(如SIB1)传输的传输周期，根据约定关系确定系统信息(如SIB1)的传输时机，只在这些传输时机上进行系统信息(如SIB1)的检测。当然，还可采用其他约定关系确定传输时机，本实施例中对此不做限定。
在本公开的一些可选实施例中，所述方法还包括：所述终端发送第一信号，所述第一信号用于请求或触发网络设备以第四周期发送发送系统信息和/或类型0-PDCCH；所述终端以第四周期在第四传输时机接收系统信息和/或类型0-PDCCH。
本实施例中，在采用上述PBCH指示类型0-PDCCH的传输时机或者传输周期和/或系统信息的传输时机或者传输周期的情况下，类型0-PDCCH的传输周期和/或系统信息的传输周期可能较长，大于常规的20ms。若终端对时延要求较高，则终端还可以主动发起请求，请求或触发网络设备以第四周期(20ms)发送系统信息。其中，所述第一信号例如可以使用物理随机接入信道(PRACH，Physical Random Access Channel)类似的前导码(preamble)，即终端通过发送前导码请求或触发网络设备以第四周期发送系统信息和/或类型0-PDCCH。进一步地，网络设备接收到第一信号后，以第四周期(20ms)在第四传输时机发送系统信息和/或类型0-PDCCH。
