具体实施方式
下面将参照附图更详细地描述本公开的示例性实施例。虽然附图中显示了本公开的示例性实施例，然而应当理解，可以以各种形式实现本公开而不应被这里阐述的实施例所限制。相反，提供这些实施例是为了能够更透彻地理解本公开，并且能够将本公开的范围完整的传达给本领域的技术人员。
本申请的说明书和权利要求书中的术语“第一”、“第二”等是用于区别类似的对象，而不必用于描述特定的顺序或先后次序。应该理解这样使用的数据在适当情况下可以互换，以便这里描述的本申请的实施例例如能够以除了在这里图示或描述的那些以外的顺序实施。此外，术语“包括”和“具有”以及他们的任何变形，意图在于覆盖不排他的包含，例如，包含了一系列步骤或单元的过程、方法、系统、产品或设备不必限于清楚地列出的那些步骤或单元，而是可包括没有清楚地列出的或对于这些过程、方法、产品或设备固有 的其它步骤或单元。
在4G和5G通信系统中处于无线资源控制层空闲态(Radio Resource Control idle，RRC_idle)下的终端需要在预配置的时间上检测网络设备发送的寻呼信号，具体寻呼信号过程如下：盲检测寻呼无线网络临时标识(Paging Radio Network Temporary Identity，P-RNTI)对应的PDCCH，如果没有检测到该PDCCH，则结束本次检测；如果检测到PDCCH存在，则进一步检测该PDCCH指示的物理下行共享信道(Physical Downlink Share Channel，PDSCH)，若检测出的PDSCH不是该终端的寻呼信号，则结束检测。在RRC_idle状态下，终端周期性的检测寻呼信号，每次检测PDCCH和PDSCH的功耗较大，但检测到属于自身的寻呼信号的概率较低，不利于终端省电。
在非连续接收(Discontinuous Reception，DRX)场景下，其中，DRX的基本机制是：为处于连接(RRC_connected)状态下的终端配置一个DRX周期(cycle)，如图1所示，图1表示DRX周期的时域示意图，该DRX cycle包括激活期(On Duration)和休眠期(Opportunity for DRX)，在激活期内终端监听并接收PDCCH，在休眠期内终端不接收下行信道的数据以节省功耗。也就是说，在时域上，时间被划分为一个个连续的DRX cycle。其中，DRX起始偏移(drxStartOffset)用于指示DRX cycle的起始子帧，长DRX周期(longDRX-Cycle)用于指示long DRX cycle占用多少个子帧。其中，这两个参数都是由longDRX-CycleStartOffset字段确定的。激活期定时器(On Duration Timer)指定了从DRX cycle的起始子帧算起，需要监听PDCCH的连续子帧数(即激活期持续的子帧数)。
在大多数情况下，当一个终端在某个子帧被调度并接收或发送数据后，很可能在接下来的几个子帧内继续被调度，如果等到下一个DRX cycle再进行接收或发送，这些数据将会带来额外的延迟。为了降低此类延迟，终端在被调度后会持续处于激活期，即会在配置的激活期内持续监听PDCCH。具体地，在终端被调度初传数据时，会启动或重启一个去激活定时器(drx-InactivityTimer)，在该定时器未超时期间终端始终处于激活期。其中，drx-InactivityTimer指定了当终端成功解码一个指示初传的上行(Uplink，UL)或下行(Downlink，DL)用户数据的PDCCH后，持续位于激活态的连续子 帧数。即每当终端有初传数据被调度，该定时器就重启一次。
本公开的一些实施例提供了一种信息检测方法，应用于终端，如图2所示，该方法包括以下步骤：
步骤21：检测网络设备发送的提前指示信号。
其中，提前指示信号包括：唤醒信号WUS和睡眠信号GTS中的至少一种。
为了在DRX场景下，进一步节省盲检测Paging信号或PDCCH的功耗，提出了WUS和GTS的概念，其中，WUS和GTS统称为提前指示信号。其中，在idle状态或者RRC connected状态的每一个DRX周期中，或者在RRC connected状态(DRX OFF)时，终端在盲检测Paging信号或PDCCH之前，网络设备首先传输一个WUS给终端，终端在相应时刻醒过来检测该WUS。若终端检测到该WUS，则终端盲检测Paging信号或PDCCH；否则，该终端不盲检测Paging信号或PDCCH，并继续休眠。如图3所示，假设网络设备为终端配置WUS时，终端可在物理信道检测WUS，若检测到WUS，则确定在下一个DRX周期内需要进行PDCCH检测，若未检测到WUS，则确定在下一个DRX周期内无需进行PDCCH检测，继续保持休眠状态。或者，在idle状态或者RRC connected状态的每一个DRX周期中，终端在盲检测Paging信号或PDCCH之前，网络设备还可以传输一个GTS给终端，终端在相应时刻醒过来检测该GTS。若终端检测到该GTS，则终端不盲检测Paging信号或PDCCH，并继续休眠；否则，终端盲检测Paging信号或PDCCH。其中，检测WUS或GTS相比盲检测Paging信号或PDCCH复杂度更低且更为省电。
进一步地，目前提前指示信号(包括WUS或GTS)的设计包括下面几种：OOK(on-off keying)、具有不连续发送或者没有不连续发送的序列(with or without DTX)、经过信道编码的载荷(payload)如PDCCH等、序列+载荷(如接收序列完成同步，然后在同步状态下接收payload)。
其中，以序列为例，提前指示信号可以是不连续发送(Discontinuous Transmission，with DTX)或者没有不连续发送(without DTX)的。以with DTX为例：当提前指示信号承载WUS序列时，若终端检测到该WUS序列，则确定在下一个DRX周期内需要进行PDCCH检测，若未检测到该WUS序列， 则确定在下一个DRX周期内无需进行PDCCH。同理，当提前指示信号承载GTS序列时，若未检测到该GTS序列，则确定在下一个DRX周期内需要进行PDCCH检测，若检测到该GTS序列，则确定在下一个DRX周期内无需进行PDCCH检测。以without DTX为例：当提前指示信号承载WUS序列时，若检测到WUS序列为第一序列格式，则确定在下一个DRX周期内需要检测对应的PDCCH，若检测到WUS为第二序列格式，则确定在下一个DRX周期内无需检测对应的PDCCH，终端继续睡眠。同理，当提前指示信号承载GTS序列时，若检测到GTS序列为第三序列格式，则确定在下一个DRX周期内需要检测对应的PDCCH，若检测到GTS为第四序列格式，则确定在下一个DRX周期内无需检测对应的PDCCH，终端继续睡眠。
步骤22：若提前指示信号指示检测物理下行控制信道PDCCH，则通过目标传输资源检测PDCCH。
其中，这里所说的目标传输资源尤其指的是目标频域资源，包括目标带宽(bandwidth)、目标带宽部分(Bandwidth Part，WP B)、目标信道(channel)等。5G系统中为了节省电量，终端可以工作在一个比较小的工作带宽(如5MHz)，而网络设备的一个小区会配置比较大的系统带宽(如100MHz)，该大带宽中的终端工作的小带宽部分则认为是带宽部分(Bandwidth Part，BWP)，当然BWP也可以配置为整个系统带宽。网络设备可以为终端配置1个或多个BWP，并通过激活或去激活BWP的方式变换终端工作的BWP。
在一种可选实施例中，目标传输资源可以通过但不限于以下方式之一确定：预定义方式确定，根据终端的标识信息确定，根据提前指示信号所在频域资源确定，以及根据提前指示信号所在频域资源确定。
其中，预定义方式确定，例如：目标BWP为协议预定义确定的，如协议预定义第一个BWP为目标BWP；
网络设备配置或重配置方式确定，如目标BWP为网络设备配置或重配置的；其中，网络设备可通过预设信令将目标传输资源指示给终端，相应地，终端在步骤22之前还包括：接收网络设备通过预设信令发送的目标传输资源的指示信息。其中，预设信令包括但不限于：主系统信息块(Master Information Block，MIB)，系统信息块(System Information Block，SIB)，无线资源控制 (Radio Resource Control，RRC)信令，媒体接入控制(Media Access Control，MAC)控制单元(Control Element，CE)和物理层信令(L1signaling，如PDCCH)的至少一项。
可选地，接收网络设备通过预设信令发送的目标传输资源的指示信息的步骤可参照以下方式实现：接收网络设备通过RRC信令发送的指示信息；将指示信息指示的N个带宽部分BWP中的一个，确定为目标传输资源，其中，N为大于或等于1的整数。也就是说，终端将网络设备通过RRC信令配置下来的多个BWP中的一个作为目标BWP。例如：目标BWP可以是RRC信令配置的最大4个BWP中的一个。其中，网络设备为每个终端配置最多4个下行BWP和最多4个上行BWP。
在一种可选实施例中，将指示信息指示的N个带宽部分BWP中的一个，确定为目标传输资源的步骤，包括：将指示信息指示的N个BWP中除带宽最大的前M个BWP之外的其他BWP中的一个，确定为目标传输资源，其中，M为大于或等于1的整数。也就是说，终端还可以将RRC信令配置的最大的4个BWP之外的一个BWP确定为目标BWP，即目标BWP不属于RRC信令配置的最大4个BWP中的一个。可选地，还可以将指示信息指示的N个BWP中除带宽最大的BWP之外的其他BWP中的一个，确定为目标传输资源。
根据终端的标识信息(UE ID)确定，如目标BWP根据UE ID计算得到，具体为：通过哈希函数将终端的标识(UE ID)映射到N组下行BWP上；UE ID包括国际移动用户识别码(International Mobile Subscriber Identity，IMSI)、分组域用户临时标识符(Packet-Temporary mobile subscriber identification，P-TMS)、用户临时标识符(Temporary mobile subscriber identification，TMS)或者短格式；
根据提前指示信号所在频域资源确定，即目标传输资源的频域位置与提前指示信号所在频域资源的位置相关联。
可选地，当目标传输资源根据提前指示信号所在频域资源确定时，目标传输资源可以是提前指示信号所在频域资源，即目标BWP与提前指示信号所在BWP相同。或者，目标传输资源是与提前指示信号所在频域资源相对应的 频域资源，即根据目标BWP与提前指示信号所在BWP的预设资源映射关系(或称为映射表)，以及提前指示信号所在BWP来确定目标带宽部分。
也就是说，当目标传输资源根据提前指示信号所在频域资源确定时，步骤22包括：通过提前指示信号所在频域资源检测PDCCH；或者，根据预设资源映射关系，通过与提前指示信号所在频域资源相对应的目标频域资源检测PDCCH；其中，预设资源映射关系为目标传输资源与提前指示信号所在频域资源的对应关系。预设资源映射关系(即目标BWP与提前指示信号所在BWP的映射表)具体举例为：目标BWP1对应着BWP 1，目标BWP2对应着BWP 2，...，目标BWP N对应着BWP N等。当提前指示信号所在BWP为BWP2时，PDCCH的检测位置为目标BWP2。其中，预设资源映射关系为预定义的、网络设备配置或重配置的。
另外，在另一种可选实施例中，为了确定终端是否检测到提前指示信号，步骤21之后，还包括：若检测到提前指示信号，则向网络设备反馈一应答信息ACK；或者，若未检测到提前指示信号，则向网络设备反馈一非应答信息NACK。
可选地，提前指示信号还用于指示但不限于以下终端行为中的至少一项：
终端激活第一激活载波集，其中，第一激活载波集包括主小区(Primary cell，Pcell)、辅小区(Secondary cell，Scell)和主辅小区(Primary Secondary cell，PScell)中的至少一项；第一激活载波集为网络设备通过预设信令(或称为预设信息或预设信道)配置给终端的。其中，预设信令包括：主系统信息块MIB、系统信息块SIB、无线资源控制RRC信令、媒体接入控制MAC控制单元CE和物理层信令(如PDCCH)中的至少一项。终端检测到提前指示信号后的第一激活载波集(first active Component Carrier set)，包括Pcell、Pcell和Scell，first active CC set是网络设备配置或重配置的，或者协议预定义的；若first active CC set为网络设备配置或重配置的具体为：网络设备通过MIB、SIB、RRC信令、MAC CE和物理层信令的至少一项配置。
终端在目标传输资源上读取系统信息块SIB和主系统信息块MIB中的至少一项；其中，提前指示信号指示终端读取SIB(或者RMSI或OSI)，或者读取MIB/PBCH，具体为：不同WUS序列或不同GTS序列指示不同的终端 行为，若终端检测到指示读取SIB的目标WUS序列，则终端读取SIB。
终端在目标传输资源上进行下行同步；其中，提前指示信号指示终端进行下行同步，其中，下行同步包括通过同步信号块(Synchronous Signal Block，，SSB)同步或者通过信道状态指示参考信号(Channel State Information Reference Signal，CSI-RS)同步。其中，同步信号块(Synchronous Signal Block，SS Block)，占用20个资源块(Resource Block，RB)，在15KHz的子载波间隔(Sub-carrier Spacing，SCS)时20个RB总共占用了3.6MHz的带宽。其中，SS Block中包括：主同步信号(Primary Synchronous Signal，PSS)、辅同步信号(Secondary Synchronous Signal，SSS)和物理广播信道(Physical Broadcast Channel，PBCH)。终端和一个小区进行同步(包括时间同步和频率同步)并获取到对应的定时关系，该定时关系包括子帧编号(subframe number)和系统帧编号(System Frame Number，SFN)。当需要读取到该小区的特定的SS Block时，例如该SS Block关联RMSI或OSI时，该特定的SS Block被称为小区定义的SS Block(cell-defining SS Block)。
终端在目标传输资源上进行重附着；其中，提前指示信号指示终端重新做一次附着(Attach)过程。
终端在目标传输资源上读取商用移动告警系统指示(Commercial Mobile Alert Service Indication，cmas-Indication)信息和地震海啸预警系统指示(Earthquake Tsunami Early Warning System Indication，etws-Indication)信息；也就是说，提前指示信号指示终端读取cmas-Indication和/或etws-Indication信息。终端检测到指示读取cmas-Indication和/或etws-Indication信息的目标WUS序列时，读取cmas-Indication和/或etws-Indication。
终端在目标传输资源上发送物理随机接入信道(Physical Random Access Channel，PRACH)或探测参考信号(Sounding Reference Signal，SRS)，也就是说，提前指示信号指示终端在目标载波或目标BWP上发PRACH或SRS。目标载波或BWP是网络设备配置或重配置的，或者协议预定义的，或者根据UE ID计算出来的，或者根据提前指示信号所在BWP确定出来的。
其中，上述目标传输资源包括：目标载波或目标BWP，或者目标PRB组。
本公开的一些实施例的信息检测方法中，终端在提前指示信号指示终端需要检测PDCCH时，终端在目标传输资源上进行PDCCH的检测，其中，目标传输资源的确定可通过预定义方式、网络设备配置或重配置方式、根据终端的标识信息计算方式、根据提前指示信号所在频域资源确定方式等确定，这样终端即可确定PDCCH的具体检测位置，从而降低了终端盲检PDCCH的复杂度。

如图6所示，本公开的一些实施例的信息传输方法，应用于网络设备，包括以下步骤：
步骤61：向终端发送提前指示信号。
其中，提前指示信号包括：唤醒信号WUS和睡眠信号GTS中的至少一种。进一步地，目前提前指示信号(包括WUS或GTS)的设计包括下面几种：OOK(on-off keying)、序列(with or without DTX)、经过信道编码的载荷(payload)如PDCCH等、序列+载荷(如接收序列完成同步，然后在同步状态下接收payload)。以序列为例，提前指示信号可以是不连续发送(Discontinuous Transmission，with DTX)或者without DTX的。
步骤62：若提前指示信号指示检测物理下行控制信道PDCCH，则通过目标传输资源向终端发送PDCCH。
其中，这里所说的目标传输资源尤其指的是目标频域资源，包括目标带宽(bandwidth)、目标带宽部分(Bandwidth Part，WP B)、目标信道(channel)等。
其中，目标传输资源通过以下方式之一确定：
预定义方式确定，例如：目标BWP为协议预定义确定的，如协议预定义第一个BWP为目标BWP。
网络设备配置或重配置方式确定，如目标BWP为网络设备配置或重配置的；当目标传输资源为网络设备配置或重配置方式确定时，通过目标传输资源向终端发送所述PDCCH的步骤之前还包括：通过预设信令向终端发送目标传输资源的指示信息；其中，预设信令包括：主系统信息块MIB、系统信息块SIB、无线资源控制RRC信令、媒体接入控制MAC控制单元CE和物理层信令中的至少一项。可选地，通过预设信令向终端发送目标传输资源的指示信息的步骤包括：通过RRC信令向终端发送的指示信息；其中，目标传输资源为指示信息指示的N个带宽部分BWP中的一个，例如：目标BWP可以是RRC信令配置的最大4个BWP中的一个。另一种特殊实施例中，目标传输资源为N个BWP中除带宽最大的前M个带宽部分BWP之外的其他BWP中的一个，其中，M为大于或等于1的整数，如终端还可以将RRC信令配置的最大的4个BWP之外的一个BWP确定为目标BWP，即目标BWP不属于RRC信令配置的最大4个BWP中的一个。可选地，还可以将指示信息指示的N个BWP中除带宽最大的BWP之外的其他BWP中的一个，确定为目标传输资源。
根据终端的标识信息确定，如目标BWP根据UE ID计算得到，具体为：通过哈希函数将UE ID映射到N组下行BWP上；UE ID包括IMSI、P-TMS、TMS或者短格式。
根据提前指示信号所在频域资源确定。
可选地，当目标传输资源根据提前指示信号所在频域资源确定时，通过目标传输资源向终端发送PDCCH的步骤包括：通过提前指示信号所在频域资源向终端发送所述PDCCH，即目标BWP与提前指示信号所在BWP相同。
或者，根据预设资源映射关系，通过与提前指示信号所在频域资源相对应的目标频域资源向所述终端发送所述PDCCH。其中，预设资源映射关系为目标传输资源与提前指示信号所在频域资源的对应关系。即根据目标BWP与提前指示信号所在BWP的预设资源映射关系(或称为映射表)，以及提前指示信号所在BWP来确定目标带宽部分。其中，预设资源映射关系为预定义的、网络设备配置或重配置的。
另外，在另一种可选实施例中，为了确定终端是否检测到提前指示信号， 向终端发送提前指示信号的步骤之后，还包括：接收终端在检测到所述提前指示信号时反馈的应答信息ACK；或者，接收终端在未检测到所述提前指示信号时反馈的非应答信息NACK。

终端在目标传输资源上读取系统信息块SIB和主系统信息块MIB中的至少一项。
终端在目标传输资源上进行下行同步。

终端在目标传输资源上发送物理随机接入信道或探测参考信号。其中，上述目标传输资源包括：目标载波或目标BWP，目标传输资源为预定义、网络设备配置或重配置、或者根据终端的标识信息确定的。
其中值得指出是，上述提前指示信号的具体指示实施例与终端侧实施例相似，为避免重复，故不再一一赘述。
本公开的一些实施例的信息传输方法中，网络设备在提前指示信号指示终端需要检测PDCCH时，在目标传输资源上传输PDCCH，其中，目标传输资源的确定可通过预定义方式、网络设备配置或重配置方式、根据终端的标识信息计算方式、根据提前指示信号所在频域资源确定方式等确定，这样网络设备和终端均可确定PDCCH的具体检测位置，在终端盲检PDCCH时可降低盲检复杂度。
