图2为本申请一实施例提供的检测窗指示方法流程示意图，如图2所示，该方法包括：
S201、网络设备生成控制信道的配置信息。
该控制信道的配置信息包括控制信道的检测窗指示信息字段，一个控制信道的检测窗指示信息字段用于指示下述至少一项：检测窗的时间长度、检测窗的周期、检测窗的时域起始位置信息。
具体地，控制信道的检测窗指示信息字段指示检测窗的时间长度、检测窗的周期、检测窗的时域起始位置信息中任意一项时，另外两项可以是预设的或者根据预设的映射关系获取。
举例说明，
a)控制信道的检测窗指示信息字段指示检测窗的时间长度时，检测窗的周期和检测窗的时域起始位置信息可以是预设的检测窗的周期、预设的检测窗的时域起始位置信息。
或者，网络设备/终端根据控制信道对应的载频、以及该载频与控制信道检测窗的时域起始位置信息的映射关系，获取检测窗的时域起始位置信息。网络设备/终端可以根据公共信号块的周期、公共信号块的周期与检测窗的周期之间的映射关系，获取检测窗的周期。
或者，检测窗的时域起始位置信息，根据检测窗的时域起始位置信息与检测窗的时间长度的映射关系、以及检测窗的时间长度确定；类似地，检测窗的周期，根据检测窗的周期与检测窗的时间长度的映射关系、以及检测窗的时间长度确定。
b)控制信道的检测窗指示信息字段指示检测窗的周期时，检测窗的时间长度和检测窗的时域起始位置信息可以是预设的检测窗的时间长度、预设的检测窗的时域起始位置信息。
或者，网络设备/终端根据控制信道对应的载频、以及该载频与控制信道检测窗的时域起始位置信息的映射关系，获取检测窗的时域起始位置信息。网络设备/终端根据控制信道对应的载频、以及该载频与检测窗的时间长度的映射关系，获取检测窗的时间长度。

c)控制信道的检测窗指示信息字段指示检测窗的时域起始位置信息时，检测窗的时间长度为预设检测窗的时间长度，检测窗的时域起始位置信息为预设检测窗的时域起始位置信息。
或者，网络设备/终端根据控制信道对应的载频、以及该载频与检测窗的时间长度的映射关系，获取检测窗的时间长度。网络设备/终端可以根据公共信号块的周期、公共信号块的周期与检测窗的周期之间的映射关系，获取检测窗的周期。

或者，进一步地，一个控制信道的检测窗指示信息字段用于指示下述至少两项：检测窗的时间长度、检测窗的周期、检测窗的时域起始位置信息。
本申请中，一个控制信道的检测窗指示信息字段可以包括1个或多个比特位，该字段的值对应不同的检测窗指示信息。例如，该字段的某个值对应一组：检测窗的时间长度，检测窗的周期，或者，该字段的某个值对应一组：检测窗的时间长度、检测窗的时域起始位置信息，或者，该字段的某个值对应一组：检测窗的周期、检测窗的时域起始位置信息，或者，该字段的某个值对应一组：检测窗的时间长度，检测窗的周期，检测窗的时域起始位置信息。
其中，上述检测窗的时域起始位置信息可以是一个时间位置信息。例如，第几个slot，第几个符号，或者第几个slot的第几个符号，也可以是该检测窗相对某个参考点的一个偏置量(即，相对时间位置信息)，例如是与slot或者符号的offest；终端可以根据检测窗的时域起始位置信息确定出该检测窗的时域起始位置。
可选地，该参考点可以是某个公共信号块对应的时间点，如，第i个SS/BCH block，i为大于等于1的自然数，该参考点也可以是某个其他时间点，如某个固定帧，固定时隙，或固定符号等。该参考点可以是预定义的或隐式指示的，这里不做具体限定。
可选的，每个SS/BCH block关联一个控制信道的检测窗，检测窗的时域起始位置(例如起始slot)可以根据第一个SS/BCH block关联的检测窗与系统帧的起始时域位置的偏移offset，和该检测窗关联的SS/BCH block的索引index确定。其中，第一个SS/BCH block关联的检测窗与系统帧的起始时域位置的偏移offset可以根据协议确定，例如，根据一个固定值和子载波间隔确定。
可选的，在确定起始的slot之后，还可以再确定在该slot中偏移几个符号，即可以理解为从该slot的第几个符号开始。具体第几个符号可以根据系统设定或者协议约定确定。
采用本申请提供的方式，就不用“检测窗的时间长度，检测窗的周期，检测窗的时域起始位置信息”等各项检测窗信息各占用几个比特位了，通过联合编码用一个字段就可以指示出至少两项检测窗信息的组合，从而节约了比特位。需要说明的是，这里不排除可以将上述至少一项检测窗信息与控制信道的其他配置信息，如控制信道资源集合的大小，控制信道资源集合的时间间隔，控制信道资源集合的梳齿信息等中的至少一个进行联合编码和指示，这里不做具体限定。

S202、网络设备向终端发送该控制信道的配置信息。
可选地，网络设备通过物理广播信道向终端发送控制信道的配置信息。
S203、终端根据该控制信道的配置信息确定该控制信道的检测窗。
终端获取了控制信道的配置信息后，可以确定出该控制信道的检测窗。网络设备在检测窗内的某个时频资源上发送控制信息，相应地，终端在该检测窗内进行控制信道的盲检测。
这里的控制信道可以为系统信息的控制信道或随机接入响应的控制信道或寻呼信道的控制信道，本申请不做具体限定。其中，A的控制信道指的是A的调度信道，A可以为上述系统信息，随机接入响应或寻呼信道中的任意一个。其中，系统信息的控制信道可以是CORESET of Type0-PDCCH(the control resource set of the Type0-PDCCH common search space)，其中，CORESET of Type0-PDCCH的配置信息是在MIB中指示的，可以通过MIB中的指示信息pdcch-ConfigSIB1指示，该指示信息的高4位和低4位联合指示CORESET of Type0-PDCCH的时频资源位置(例如，连续的几个RB以及连续的几个符号)。其中，Type0-PDCCH可以用于SIB1(也可以称为RMSI)调度信息的传输。
而系统信息可以为：剩余最小系统信息(Remaining Minimum System Information，RMSI)，其他系统信息(Other System Information，OSI)，或其他类型的系统信息中的任意一种，本申请不做具体限定。
本实施例中，网络设备生成控制信道的配置信息，该控制信道的配置信息包括控制信道的检测窗指示信息字段，一个控制信道的检测窗指示信息字段用于指示下述至少两项：检测窗的时间长度、检测窗的周期、检测窗的时域起始位置信息。进而网络设备将控制信道的配置信息发送给终端，终端根据控制信道的配置信息确定出该控制信道的检测窗。实现了通过一个字段指示检测窗的时间长度、检测窗的周期、检测窗的时域起始位置信息中至少两项，并实现以尽量更少的比特位指示更多信息的效果。
可选地，控制信道的检测窗指示信息字段指示下述信息中的任意两项：检测窗的时间长度、检测窗的周期、检测窗的时域起始位置信息。
相应地，除了控制信道的检测窗指示信息字段指示的两项信息以外的信息为预设信息或者由预设的映射关系确定。
即控制信道的检测窗指示信息字段指示两项信息时，其他项可以预先配置或者由预设的映射关系隐式指示。
一种实施方式中，控制信道的检测窗指示信息字段用于指示检测窗的时间长度和检测窗的周期。
例如，控制信道的检测窗指示信息字段仅包括2比特，可以指示4种“检测窗的时间长度(单位：时隙slot)和检测窗的周期(单位：毫秒ms)”的信息值。以检测窗的时间长度的可能取值集合为{1slot，2slots,4slots}，而检测窗的周期的可能取值集合为{10ms，20ms,40ms,80ms}为例：
可选地，这4种“检测窗的时间长度和检测窗的周期”的信息值可以包括：(4slots,80ms)、(2slots,40ms)、(1slot,20ms)、(1slot,10ms)；或者，
(4slots,40ms)、(2slots,20ms)、(2slots,10ms)、(1slot,10ms)；或者，
(4slots,80ms)、(2slots,40ms)、(2slots,20ms)、(1slot,10ms)。
具体地，以假设(4slot,80ms)、(2slot,40ms)、(1slot,20ms)、(1slot,10ms)4种情况为例，控制信道的检测窗指示信息字段这2比特为“00”时标识(4slot,80ms)、为“01”时标识(2slot,40ms)、为“10”时标识(1slot,20ms)、为“11”时标识(1slot,10ms)。当然不以上述举例为限。例如，检测窗的时间长度的可能取值可以为上述取值外的其他值，如8slots，而检测窗的周期的可能取值也可以为上述取值外的其他值，如160ms等，这里不做具体限定。
又例如，控制信道的检测窗指示信息字段仅包括3比特，可以指示8种“检测窗的时间长度和检测窗的周期”的信息值。以检测窗的时间长度的可能取值集合为{1slot，2slots,4 slots}，而检测窗的周期的可能取值集合为{10ms，20ms,40ms,80ms}为例。
可选地，这8种“检测窗的时间长度和检测窗的周期”的信息值可以包括：(4slots,80ms)、(4slots,40ms)、(4slots,20ms)、(2slots,40ms)、(2slots,20ms)、(2slots,10ms)、(1slot,20ms)、(1slot,10ms)；或者，
(4slots,80ms)、(4slots,40ms)、(4slots,20ms)、(4slots,10ms)、(2slots,80ms)、(2slots,40ms)、(2slots,20ms)、(2slots,10ms)。
与上例类似，控制信道的检测窗指示信息字段的不同值可以对应不同的“检测窗的时间长度和检测窗的周期”的信息值，假设“000”标识(4slots,80ms)，其他类似，不再一一赘述。
上述2比特的4种“检测窗的时间长度和检测窗的周期”的信息值和3比特的8种“检测窗的时间长度和检测窗的周期”的信息值满足：较大的检测窗的时间长度对应的检测窗周期也较大，或较大的检测窗周期对应的检测窗的时间长度也较大。即，根据检测窗的时间长度可确定检测窗的周期或根据检测窗的周期可确定检测窗的时间长度。考虑到，控制信道的调度自由度是由该控制信道的检测窗的时间长度和检测窗的周期共同决定的，而上述配置方法可实现控制信道的调度自由度的最大化。综上，该设计既可节省控制信道检测窗的指示信息比特数，又能最大化检测窗配置的灵活性，进而保证控制信道调度的自由度。
相应地，网络设备还需要获取检测窗的时域起始位置信息。终端也需要获取检测窗的时域起始位置信息。
具体实现过程中，获取检测窗的时域起始位置信息可以有下述至少一种方式：
(1)网络设备/终端获取预设的检测窗的时域起始位置信息。
即可以预先通过协议或者信息交互设置好检测窗的时域起始位置信息。(2)控制信道检测窗的时域起始位置信息与控制信道对应的载频相关。
具体可以是网络设备/终端根据控制信道对应的载频、以及该载频与控制信道检测窗的时域起始位置信息的映射关系，获取检测窗的时域起始位置信息。
即预先设置载频与控制信道检测窗的时域起始位置信息的映射关系。
以检测窗的时域起始位置信息为检测窗相对某个参考点的一个偏置量为例，例如：控制信道对应的载频频段小于6千兆赫兹(GHz)时，检测窗相对SS/BCH block的偏置量为0个时间单位；而在控制信道对应的载频频段大于或等于6GHz时，检测窗相对SS/BCH block的偏置量为M个时间单位，M为大于0的实数。这里对M的具体值不作限制，时间单位可以是时隙，半帧，帧，SS/BCH块的时间间隔或至少一个符号的短时隙等中的至少一个。应理解，这里对于载频频段的分类只是一种可能的示例，不排除可以有其他的载频频段的分类方法。
(3)检测窗的时域起始位置信息由检测窗的时间长度和/或检测窗的周期隐式指示。
具体可以是网络设备/终端根据检测窗的时间长度和/或检测窗的周期，获取检测窗的时域起始位置信息。
检测窗的时间长度和检测窗的周期确定后，网络设备/终端根据检测窗的时间长度、以及检测窗的时间长度与检测窗的时域起始位置信息的映射关系可以获取检测窗的时域起始位置信息。例如：检测窗的时间长度越大，指示检测窗的时域起始位置信息的偏置量就越大。或者直接配置检测窗的时间长度的某个值对应检测窗的时域起始位置的某个值。
或者，网络设备/终端根据检测窗的周期、以及检测窗的周期与检测窗的时域起始位置信息的映射关系可以获取检测窗的时域起始位置信息。类似地，可以是检测窗的周期越大，指 示检测窗的时域起始位置信息的偏置量就越大。或者直接配置检测窗的周期的某个值对应检测窗的时域起始位置的某个值。
或者，网络设备/终端根据检测窗的时间长度和检测窗的周期、以及“检测窗的时间长度和检测窗的周期”与检测窗的时域起始位置信息的映射关系可以获取检测窗的时域起始位置信息。在此不作限制。类似地，可以是检测窗的时间长度越大、检测窗的周期越大。或者直接配置检测窗的时间长度的某个值对应检测窗的周期的某个值。
终端获取检测窗的时域起始位置信息的方法，可以参照上述网路设备获取检测窗的时域起始位置信息的方法。
另一种可能的实施方式中，控制信道的检测窗指示信息字段用于指示检测窗的时域起始位置信息和所述检测窗的时间长度。
例如，控制信道的检测窗指示信息字段包括3比特，可以指示8种“检测窗的时域起始位置信息和检测窗的时间长度”的信息值。
可选地，这8种“检测窗的时域起始位置信息和检测窗的时间长度”的信息值包括：(0offset,1slot)、(0offset,2slot)、(0offset,4slot)、(1offset,1slot)、(1offset,2slot)、(m offset,1slot)、(m offset,2slot)、(m offset,4slot)。其中，m为大于0的实数。
其中，检测窗的时间长度可以是由N个时间单元组成，时间单元可以是slot、mini-slot(1个或多于1个符号)、帧、子帧、半帧、一个控制信道资源集合对应的时域间隔、一个公共信号块对应的时域间隔等。offset标识检测窗的偏置量单位，1个offset也可以是下述一种量级的时间：slot、mini-slot(1,2,4,7符号的时域间隔)、帧、子帧、半帧、一个控制信道资源集合对应的时域间隔、一个公共信号块对应的时域间隔等，在此不具体限定。
控制信道的检测窗指示信息字段的不同值标识不同的“检测窗的时域起始位置信息和检测窗的时间长度”。假设“000”标识(0offset,1slot)，其他类似，在此不具体限定。
相应地，网络设备还要获取检测窗的周期。终端收到配置信息后，也需要获取检测窗的周期。
与前述实施例类似地，网络设备获取检测窗的周期，可以下述至少一种方式：
(1)网络设备/终端获取预设的检测窗的周期。
即预先设置或确定检测窗的周期。
(2)检测窗的周期与公共信号块的周期相关。这里，该公共信号块可以包括：同步信号(synchronization signal，SS)块(block)、物理广播信道(physical broadcast channel，PBCH)块中至少一个。可以记为SS/PBCH block。
具体地，网络设备/终端可以根据公共信号块的周期，获取检测窗的周期。例如可以预先设置或确定公共信号块的周期与检测窗的周期之间的映射关系，这样在获取公共信号块的周期之后，就可以得到控制信道检测窗的周期。可选地，可以预定义控制信道检测窗的周期等于公共信号块的周期。或，预定义控制信道检测窗的周期等于公共信号快周期的k倍，这里k是预定义的自然数。
(3)检测窗的周期由检测窗的时间长度和/或检测窗的时域起始位置信息隐式指示。
检测窗的时间长度和检测窗的时域起始位置信息确定后，网络设备/终端根据检测窗的时间长度、以及检测窗的时间长度与检测窗的周期的映射关系可以获取检测窗的周期。可以是检测窗的时间长度越大、检测窗的周期越大。或者直接配置检测窗的时间长度的某个值对应检测窗的周期的某个值。
或者，网络设备/终端根据检测窗的时域起始位置信息、以及检测窗的时域起始位置信息 与检测窗的时域起始位置信息的映射关系可以获取检测窗的周期。类似地，可以是指示检测窗的时域起始位置信息的偏置量越大、检测窗的周期也越大。或者直接配置检测窗的时域起始位置的某个值对应检测窗周期的某个值。
或者，网络设备/终端根据检测窗的时间长度和检测窗的时域起始位置信息、以及“检测窗的时间长度和检测窗的时域起始位置信息”与检测窗的周期的映射关系可以获取检测窗的周期。在此不作限制。可以是检测窗的时间长度越大、指示检测窗的时域起始位置信息的偏置量越大。或者直接配置检测窗的时间长度的某个值对应指示检测窗的时域起始位置的某个值。
网络设备/终端根据检测窗的时域起始位置信息、以及检测窗的时域起始位置信息与检测窗的时域起始位置信息的映射关系可以获取检测窗的周期。可选地，该检测窗的时域起始位置信息为该检测窗相对网络设备发送的第一个公共信号块集合(SS burst set)的第一个公共信号块(SS block)的相对时间偏移量，基于此偏移量终端可推断得到检测窗的周期信息。
终端收获取检测窗的周期的具体过程，可以参照上述网络设备获取检测窗的周期的过程，在此不再赘述。
一种实施例中，所述控制信道的检测窗指示信息字段用于指示检测窗的时域起始位置信息和所述检测窗的周期；
所述方法还包括：
所述网络设备获取所述检测窗的时间长度。
一种可能的设计中，所述网络设备获取所述检测窗的时间长度，包括下述至少一种方式：
所述网络设备获取预设的所述检测窗的时间长度；
所述网络设备根据所述控制信道对应的载频、以及所述载频与所述检测窗的时间长度的映射关系，获取所述检测窗的时间长度；
所述网络设备根据所述检测窗的时域起始位置信息和/或所述检测窗的周期，获取所述检测窗的时间长度。
终端侧获取检测窗的时间长度过程，可以参照网络设备获取检测窗的时间长度，不再赘述。
另一种实施例中，控制信道的检测窗指示信息字段指示“检测窗的时间长度，检测窗的周期，检测窗的时域起始位置信息”三者的组合。
这种情况下，其中一项的值可以由另外一项或两相决定。
例如，检测窗的时间长度根据检测窗的周期和/或检测窗的时域起始位置信息确定；例如检测窗的周期和/或检测窗的时域起始位置信息(指示检测窗的时域起始位置信息的偏置量)越大，检测窗的时间长度就越大。
检测窗的周期根据检测窗的时间长度和/或检测窗的时域起始位置信息确定；例如检测窗的时间长度和/或检测窗的时域起始位置信息(指示检测窗的时域起始位置信息的偏置量)越大，检测窗的周期就越大。
检测窗的时域起始位置信息根据检测窗的时间长度和/或检测窗的周期确定；例如检测窗的时间长度和/或检测窗的周期越大，检测窗的时域起始位置信息(指示检测窗的时域起始位置信息的偏置量)就越大。
在上述实施例的基础上，检测窗的周期或检测窗的周期的取值范围可以根据系统信息传输时间间隔确定。
确定上述配置信息之前，可以先根据系统信息传输时间间隔(RMSI TTI)确定检测窗的 周期或检测窗的周期的取值范围，这样可以进一步减少“检测窗的时间长度、检测窗的周期、检测窗的时域起始位置信息”组合的可能性，从而可以使得检测窗指示信息字段所需的比特位更少。
例如：RMSI TTI为80ms时，检测窗的周期可以为下述集合中的至少一种{10ms，20ms，40ms，80ms}。
RMSI TTI为160ms时，检测窗的周期可以为下述集合中的至少一种{20ms，40ms，80ms，160ms}。
而系统信息传输时间间隔也需要通过物理广播信道发送给终端，为节省广播信道的信令开销，该系统信息传输时间间隔可以是预定义的或隐式指示的。
可选地，网络设备和终端侧预定义一个系统信息传输的重复次数，通过广播信道中配置的系统信息传输时间间隔和此预定义的重复次数，可隐式确定系统信息控制信道检测窗的周期。反之亦然，预定义一个系统信息传输的重复次数，通过广播信道配置的系统信息控制信道检测窗周期和此预定义的重复次数，可隐式确定系统信息的传输时间间隔。
另一种实施方式中，网络设备和终端侧可预定义系统信息的传输时间间隔，通过在广播信道中配置的系统信息传输的重复次数和此预定义的传输时间间隔，可隐式确定系统信息控制信道检测窗的周期；或，通过广播信道中配置的系统信息控制信道检测窗的周期和此预定义的传输时间间隔，可隐式确定系统信息传输的重复次数。
可选地，网络设备和终端侧也可预定义控制信道检测窗的周期，通过广播信道中配置的系统信息的传输时间间隔和此预定义的检测窗周期，可隐式确定系统信息传输的重复次数；或，通过广播信道中配置的系统信息传输的重复次数和此预定义的检测窗周期，可隐式确定系统信息的传输时间间隔。
另外，上述检测窗的时间长度和检测窗的周期可以相互关联，可以实现系统信息控制信道资源调度的灵活性。
例如：检测窗的时间长度由检测窗的周期确定。或者，检测窗的周期由检测窗的时间长度确定。
图3为本申请中检测窗的结构示意图。每个阴影的方块标识一个检测窗。
如图3所示，检测窗的时间长度越长，检测窗的周期也会越长。
或者说，检测窗的周期越长，检测窗的时间长度也会越长。
进一步地，上述控制信道的检测窗指示信息字段还可以指示控制信道的资源集合(Control Resource Set，CORESET)与公共信号块的资源复用方式。
反之，网络设备/终端也可以根据控制信道的资源集合(Control Resource Set，CORESET)与公共信号块的资源复用方式确定检测窗的指示信息字段。
例如，网络设备/终端根据CORESET与公共信号块的资源复用方式确定检测窗的时间长度值，当复用方式为频分复用方式时，检测窗的时间长度为1个slot，而当复用方式为时分复用方式时，检测窗的时间长度为大于1个slot，如2个或4个slots等。
这里资源复用方式可以包括：时分复用方式、频分复用方式等。控制信道的检测窗指示信息字段指示检测窗相关信息的同时，还可以指示控制信道的资源集合与公共信号块的资源复用方式。例如通过检测窗的信息(检测窗的时间长度、检测窗的周期、检测窗的时域起始位置信息中一项或多项)与“控制信道的资源集合与公共信号块的资源复用方式”的映射关系，间接指示控制信道的资源集合CORESET与公共信号块的资源复用方式。
可选地，假设控制信道的检测窗指示信息字段指示的检测窗的时域起始位置(以相对某 个参考点的offset为单位)和所述检测窗的时间长度(以slot为单位)为下述一种：(0,1)、(m,1)、(m,2)、(m,4)，其中，m为大于0实数。
在此基础上，(0,1)对应的控制信道的资源集合与公共信号块的资源复用方式为频分复用方式。
(m,1)或(m,2)或(m,4)对应的控制信道的资源集合与公共信号块的资源复用方式为时分复用方式。
展开来说，假设控制信道的检测窗指示信息字段指示“检测窗的时域起始位置(offset)和所述检测窗的时间长度(slot)”为(0,1)时，也就间接指示了(0,1)对应的控制信道的资源集合与公共信号块的资源复用方式为频分复用方式。
不以上述实施例为限，也可以预先设置“检测窗的时间长度和检测窗的周期”与控制信道的资源集合与公共信号块的资源复用方式的映射关系，其间接指示的方式类似，在此不再赘述。
进一步地，上述m还可以由该检测窗的控制信道对应的载频确定。
可以预先设置或确定控制信道对应的载频与m之间的映射关系，例如：
控制信道对应的载频小于3GHz时，m＝4。
控制信道对应的载频大于或等于3GHz、小于6GHz时，m＝8。
控制信道对应的载频大于或等于6GHz时，m＝64。
在上述实施例的基础上，检测窗的周期或检测窗的周期的取值范围可以根据系统信息传输时间间隔确定。
确定上述配置信息之前，可以先根据系统信息传输时间间隔(RMSI TTI)确定检测窗的周期或检测窗的周期的取值范围，这样可以进一步减少“检测窗的时间长度、检测窗的周期、检测窗的时域起始位置信息”组合的可能性，从而可以使得检测窗指示信息字段所需的比特位更少。
例如：RMSI TTI为80ms时，检测窗的周期可以为下述集合中的至少一种{10ms，20ms，40ms，80ms}。
RMSI TTI为160ms时，检测窗的周期可以为下述集合中的至少一种{20ms，40ms，80ms，160ms}。
可选地，检测窗的时域起始位置信息也可以根据控制信道对应的载频确定。与前述网络设备根据控制信道对应的载频确定检测窗的时域起始位置信息不同的是，检测窗的时域起始位置信息可以为预设值时，也可以为由控制信道对应的载频隐式确定的。
例如：控制信道对应的载频频段小于6千兆赫兹(GHz)时，检测窗的时域起始位置为某个帧或某个半帧中的时间单元0；而在控制信道对应的载频频段大于或等于6GHz时，检测窗时域起始位置为某个帧或某个半帧中的时间单元M，M为大于0的实数。其中，可选地，这里的时间单元可以是slot、mini-slot(1,2,4,7符号的时域间隔)、帧、子帧、半帧、一个控制信道资源集合对应的时域间隔、一个公共信号块对应的时域间隔等，这里不做具体限定。应理解，这里对于载频频段的分类只是一种可能的示例，不排除可以有其他的载频频段的分类方法。
终端在获取控制信道对应的载频后，就可以相应地确定出检测窗的时域起始位置信息。网络设备在控制信道的配置信息之前或之后，也可以根据控制信道对应的载频检测窗的时域起始位置信息。
或者，检测窗的时域起始位置信息由对应控制信道的资源集合CORESET的时间间隔确 定。即可以由对应控制信道的资源集合CORESET的时间间隔隐式指示。
具体可以是，网络设备/终端根据CORESET的时间间隔，获取检测窗的时域起始位置信息。控制信道CORESET的时间间隔确定后，网络设备/终端根据CORESET的时间间隔、以及CORESET的时间间隔与检测窗的时域起始位置信息的映射关系可以获取检测窗的时域起始位置信息。反之也成立，即检测窗的时域起始位置信息确定后，根据检测窗的时域起始位置信息、以及CORESET的时间间隔与检测窗的时域起始位置信息的映射关系，获取CORESET的时间间隔。
或者，检测窗的时域起始位置信息由控制信道对应的系统参数确定。即可以由控制信道对应的系统参数隐式指示。
具体可以是，网络设备/终端根据控制信道对应的系统参数获取检测窗的时域起始位置信息。
控制信道对应的系统参数确定后，网络设备/终端根据该系统参数、以及控制信道的系统参数与检测窗的时域起始位置信息的映射关系可以获取检测窗的时域起始位置信息。该系统参数可以指信号传输的子载波间隔信息。这里，控制信道对应的系统参数与控制信道调度的数据信道的系统参数是相同的，即，控制信道对应的系统参数与控制信道调度的数据信道的系统参数相同。控制信道调度的数据信道可以为系统信息，随机接入相应，寻呼信道等。
类似地，检测窗的时间长度或检测窗的时间长度的取值范围也可以由所述控制信道对应的载频确定。
例如：控制信道对应的载频频段小于6GHz时，检测窗的时间长度或检测窗的时间长度的取值范围可以为下述任一项：1slot、2slots。控制信道对应的载频频段大于或等于6GHz时，检测窗的时间长度或检测窗的时间长度的取值范围可以为下述任一项：2slots、4slots。需要说明的是，这里对于载频频段的分类只是一种可能的示例，不排除可以有其他的载频频段的分类方法。
终端在获取控制信道对应的载频后，也可以相应地确定出检测窗的时间长度。网络设备在控制信道的配置信息之前或之后，也可以根据控制信道对应的载频确定检测窗的时间长度或检测窗的时间长度的取值范围。
类似地，检测窗的周期也可以由所述控制信道对应的载频确定。例如：控制信道对应的载频频段小于6GHz时，检测窗的周期或检测窗周期的取值范围可以为下述任一项：10ms，20ms，40ms，80ms。
控制信道对应的载频频段大于或等于6GHz时，检测窗的周期或检测窗周期的取值范围可以为下述任一项：20ms，40ms，80ms，160ms。需要说明的是，这里对于载频频段的分类只是一种可能的示例，不排除可以有其他的载频频段的分类方法。
终端在获取控制信道对应的载频后，也可以相应地确定出检测窗的周期。网络设备在控制信道的配置信息之前或之后，也可以根据控制信道对应的载频确定检测窗的周期或检测窗的周期的取值范围。
需要说明的是，多个不同SS/BCH块关联的检测窗之间可以出现重叠或部分重叠，即多个公共信号块可以共享一个检测窗。多个连续的公共信号块关联的检测窗可以是连续的或非连续的，这里不做具体限定。
在上述实施例的基础上，网络设备还可以通过广播信道向终端指示相邻的任意两个公共信号块关联的检测窗之间的间隔值。这里的间隔值指的是时间间隔值，可以为检测窗的起始符号之间的间隔。这里的相邻指的是两个相邻的公共信号块，比如在同一个时隙中的两个相 邻的公共信号块。
可选地，网络设备可根据实际传输的公共信号块，或者公共信号块数目，灵活配置相邻的任意两个公共信号块关联的检测窗之间的时间间隔值给终端，候选的检测窗之间的时间间隔值可以包括：0,1/3,1/2,1,2等值中的至少一个。其中，0表示相邻的任意两个公共信号块关联的检测窗完全重叠，大于0小于1的候选值，如1/3,1/2表示相邻的任意两个公共信号块关联的检测窗部分重叠，大于1的候选值，如1,2表示相邻的任意两个公共信号块关联的检测窗不重叠，间隔长度为1个或2个检测窗长度。
终端根据接收到的上述时间间隔值和检测到的公共信号块时间索引确定该公共信号块关联的检测窗的实际位置。
图4为本申请另一实施例提供的检测窗指示方法流程示意图，如图4所示，该方法包括：
S401、网络设备生成控制信道的检测窗指示信息，该控制信道的检测窗指示信息用于指示下述一项或多项：检测窗的时间长度、检测窗的周期、以及检测窗的时域起始位置信息。
其中，当控制信道对应的载频为第一载频时，控制信道的检测窗指示信息由物理广播信道中N1个比特位构成。
当控制信道对应的载频为第二载频时，控制信道的检测窗指示信息由物理广播信道中N2个比特位构成。
N1大于N2，N1、N2均为大于0的整数。
需要说明的是，在不同载频下，可用的比特位数量不同，第一载频时比第二载频时可用的比特位数量多，那么在控制信道对应的载频为第一载频时，就可以使用更多的比特位来指示检测窗的信息。
S402、网络设备向终端发送检测窗指示信息。
S403、终端根据检测窗指示信息确定检测窗。
本实施例中，网络设备生成控制信道的检测窗指示信息，用于指示下述一项或多项：检测窗的时间长度、检测窗的周期、以及检测窗的时域起始位置信息。当控制信道对应的载频为第一载频时，控制信道的检测窗指示信息由物理广播信道中N1个比特位构成，当控制信道对应的载频为第二载频时，控制信道的检测窗指示信息由物理广播信道中N2个比特位构成，其中，N1大于N2。进而网络设备向终端发送检测窗指示信息，终端根据检测窗指示信息确定检测窗。实现了灵活根据不同载频下可用比特位的不同数量，尽可能用较多的比特位指示检测窗，这样也可以指示更多种不同的检测窗。
可选地，当控制信道对应的载频为第一载频时，N1个比特位包括：公共信号块的时间索引字段。
需要说明的是，当控制信道对应的载频为第一载频时，物理广播信道负载(payload)存在未使用的字段，这些未使用的空闲字段可以用来指示检测窗。
举例说明，第一载频可以为小于等于6GHz的任意载频频段，控制信道对应的载频为小于等于6GHz时，PBCH payload中存在未使用的3比特公共信号块时间索引字段，那么在本身可用作控制信道的检测窗指示信息的比特位基础上，还可以再增加3bit公共信号块时间索引字段。
相应地，第二载频为大于6GHz的任意载频频段。
进一步地，本申请还提供一种系统信息指示方法。该系统信息指示方法可以独立于本申请的其他实施方式单独存在，也可以与本申请其他实施方式的结合使用。
网络设备生成系统信息的指示信息，所述系统信息的指示信息用于指示：公共信号块对 应的系统信息是否存在，其中，所述系统信息指示信息由所述公共信号块内的物理广播信道中的N1个比特位显式或隐式指示给终端。并向终端发送上述系统信息的指示信息。终端接收上述系统信息的指示信息，然后确定系统信息。N1为大于0的整数。
其中，所述N1个比特位为用于指示物理资源块对栅格的偏移量指示信息位；或，所述N1个比特位为广播信道的CRC(Cyclic Redundancy Check，循环冗余校验)掩码指示位；或，所述N1个比特位为广播信道的公共信号块时间索引指示位和或广播信道中的系统信息控制信道配置信息指示位。
具体地，每个公共信号块关联一个系统信息的控制信道检测窗，进一步地，通常一个公共信号块关联一个系统信息(如，RMSI)。在系统带宽很宽和或多波束场景下，当小区内时域和频域上的公共信号块的个数很多而每个公共信号块均关联一个系统信息时，将导致小区内的系统信息的资源开销很大。另一方面，终端基于对多个公共信号块做联合信道质量测量可提高信道质量的测量精度，如无线资源管理(Radio Resource Management，RRM)测量的测量精度，但为获取到基本的系统接入信息则不需要读多份系统信息。因此，为减少系统信息的资源开销，避免不必要的系统信息的传输，一些公共信号块可能不会关联相应的系统信息。每个公共信号块是否关联对应的系统信息，如RMSI信息可通过基站通过广播信道显式或隐式通知给终端。即，网络设备通过每个公共信号块中的广播信道显式或隐式通知该公共信号块对应的RMSI是否存在。
其中，上述显式的方式为通过在公共信号块内的广播信道中显式增加1比特来指示该公共信号块对应的RMSI是否存在。隐式的方式为通过广播信道中一些域字段的特定状态，优选地，网络设备通过公共信号块中的广播信道指示该公共信号块对应的RMSI是否存在的方式有如下几种：
1)网络设备通过公共信号块里的广播信道中的物理资源块对栅格(又可以称为物理资源块栅格)的偏移量指示信息指示该公共信号块对应的RMSI(又可以称为SIB1)是否存在。其中，指示该公共信号块对应的SIB1是否存在，也可以认为指示的是该公共信号块对应的SIB1的调度信息是否存在。其中SIB1的调度信息可以携带在类型0物理下行控制信道的控制资源集合(CORESET of Type0-PDCCH，该控制资源集合用于Type0-PDCCH的公共搜索空间)所承载的信息中。因而，指示该公共信号块对应的SIB1是否存在，也可以认为指示的是该公共信号块对应的用于Type0-PDCCH的公共搜索空间的控制资源集合是否存在。
该物理资源块栅格偏移量可以以子载波为单位。该物理资源块对栅格的偏移量指示信息主要用作初始接入阶段RMSI及RMSI CORESET(又可以称为CORESET of Type0-PDCCH)的时频资源指示，具体用来指示公共信号块的物理资源块对栅格与系统公共物理资源块对索引间的偏移量信息(也就是公共信号块的物理资源块栅格与系统公共物理资源块对间的偏移量信息，如偏移的子载波的数目)。正常的广播信道中的物理资源块对栅格的偏移量指示信息值的取值包括{0,1,2,3,4,5,6,7,8,9,10,11}中的任意一个。当公共信号块没有对应的RMSI时，此信息域字段将存在一些特定状态，此时，网络设备通过设置广播信道中的物理资源块对栅格的偏移量指示信息值为某个特殊值，如，不同于正常的物理资源块对栅格的偏移量指示信息值的任意一个其他值，12等，而当公共信号块有对应的RMSI时，广播信道中的物理资源块对栅格的偏移量指示信息值为正常的信息指示值，即{0,1,2,3,4,5,6,7,8,9,10,11}中的任意一个，通过公共信号块内广播信道中的物理资源块对栅格的偏移量指示信息值的不同取值，可实现每个公共信号块有没有对应的RMSI的隐式指示。
2)网络设备通过公共信号块里的广播信道中的CRC掩码隐式指示该公共信号块对应的 RMSI是否存在，如，公共信号块对应的RMSI存在时对应一种掩码值，而公共信号块对应的RMSI不存在时对应另一种掩码值。
3)第一载频频段(6GHz)时，网络设备通过公共信号块里的广播信道中的公共信号块时间索引信息字段显式指示该公共信号块对应的RMSI是否存在。和/或，第二载频频段(大于或等于6GHz)时，网络设备通过公共信号块里的广播信道中的RMSI控制信道配置信息字段指示该公共信号块对应的RMSI是否存在。具体的指示方法，类似于方式1)中通过物理资源块对坐标的偏移量指示信息进行指示的方式，即通过RMSI控制信道配置信息中的任意一个或几个字段的不同取值来实现每个公共信号块有没有对应的RMSI的隐式指示。
