技术领域
本公开涉及通信应用的技术领域，尤其涉及一种信息传输方法、网络设备及终端。
背景技术
随着无线通信系统的发展，终端类型和业务类型多样化，终端省电、节约网络资源和满足各种业务类型的需求并存。其中，非连续接收(Discontinous receive，DRX)是用户设备(User Equipment，UE)(或称为终端)节电的一项重要技术方案。该方案下，UE在没有数据发送和接收需求的时候，进入DRX关闭(DRX-OFF)状态，同时UE的部分设备，例如，射频，或是基带，处于关闭或是低功耗状态，从而达到节电的目的。一旦有数据的收发，则UE需要醒来进行数据的收发。进一步的，在DRX空闲(DRX-Idle)状态下，UE周期性的在寻呼时刻(Paging occasion，PO)时刻检测寻呼paging，完成检测后，则可以进入睡眠模式，达到省电的目的。
为了进行paging的检测，在paging检测之前，UE需要进行网络同步以及时频跟踪。下一代通信(Next radio，NR)中，SS/PBCH(同步广播信号块)是周期性发送的，发送周期可以配置为5ms，10ms，20ms，40ms，80ms或160ms。所以，在UE检测paging的时刻，UE要提前完成同步和时频跟踪，例如如果UE处在强干扰环境下，或是UE处于小区覆盖边缘，或是UE处于和网络非同步的状态，此时可能需要2-3个SS/PBCH burst set(同步广播信号块发送集合)来完成同步和信道跟踪，即UE可能至少要提前醒来1个SS/PBCH周期，以免UE在PO时刻之前收不到SS/PBCH信号，无法进行paging检测。此时如果SS/PBCH周期配置较长，例如大于20ms，或是SS/PBCH  burst set内SS/PBCH的个数较少，例如，1时隙(slot)仅配置了1个SS/PBCH，则UE需要提前醒来更长的时间，从而带来更多的UE的功耗。

具体实施方式
为使本公开要解决的技术问题、技术方案和优点更加清楚，下面将结合具体实施例及附图进行详细描述。
为使本领域技术人员能够更好地理解本公开实施例的技术方案，先进行如下说明。
如图1所示，当终端处于空闲态时，进入一种极低电量的睡眠状态，终端周期性的醒来，在PO时刻检测paging信号。当数据收发完成后，UE再次进入极低电量的睡眠状态。其中，I-DRX cycle表示无线资源控制(Radio Resource Control，RRC)空闲态下的DRX周期。
相关技术中，RRC空闲(Idle)或非激活(inactivity)状态下，SS/PBCH是周期性的发送，考虑在DRX-Idle/Inactivity下，UE在paging检测之前完成同步和时频跟踪。如图2所示，不同配置和实现下，UE需要提前醒来的时间也不同。
情况一：UE和网络基本同步，UE没有落在小区边缘，且UE没有受到强干扰，且SS/PBCH配置一个slot：实现上，理想的，UE可以先缓存一个slot的数据，接收该slot数据后，UE先进行SS/PBCH的检测，获取同步信 息和时频跟踪信息，进一步的，进行paging的检测，进一步的，根据检测结果进行物理下行共享信道PDSCH的检测。其他的，更一般的情况是，UE需要提前醒来检测SS/PBCH，完成同步和时频跟踪，接下来在paging occasion的时刻，接收和检测paging。
情况二：UE和网络不同步，或UE落在小区边缘，或是UE受到强干扰：UE需要多个SS/PBCH burst set来完成同步和时频跟踪，例如，UE至少需要提前一个SS/PBCH周期醒来。或者，UE需要接收多个SS/PBCH burst set以完成同步和时频跟踪。
根据上述描述可知，为了实现同步UE至少需要提前1个SS/PBCH周期醒来，从而带来较多功耗，基于此，本公开实施例提供了一种信息传输方法，应用于网络设备，如图3所示，该方法包括：
步骤301：在目标时间窗口内，发送目标同步广播信号块SS/PBCH；
其中，所述目标时间窗口对应的时间长度小于目标发送周期对应的时间长度，所述目标发送周期为同步广播信号块SS/PBCH的发送周期，所述目标时间窗口位于寻呼时机之前，或者，所述目标时间窗口的结束时刻与所述寻呼时机所在的时刻相同，所述目标同步广播信号块SS/PBCH是指所述终端进行网络同步和/或时频跟踪所需要的至少一个同步广播信号块。例如，终端处于小区的中心位置时，所述目标广播信号块SS/PBCH可具体为一个同步广播信号块SS/PBCH，当终端处在强干扰环境下，或是终端处于小区覆盖边缘，或是终端处于和网络非同步的状态时，上述目标广播信号块SS/PBCH可具体包括多个同步广播信号块SS/PBCH。
上述目标时间窗口的时间长度可以是网络预定义的，例如，网络设备配置的当前的SS/PBCH的发送周期为160ms，则上述目标时间窗口对应的时间长度可以定义为10ms；上述目标时间窗口的时间长度也可以是网络配置或半静态配置的，例如通过无线资源控制RRC信令；上述目标时间窗口的时间长度还可通过下行控制信息(Downlink Control Information，DCI)动态配置。
具体的，所述目标时间窗口对应的时间长度小于目标发送周期对应的时间长度包括：
所述目标时间窗口的时间长度小于所述网络设备可配置的最小目标发送 周期对应的时间长度。
例如，NR-R15中目标发送周期可以配置为5ms，10ms，20ms，40ms，80ms或160ms，则上述目标时间窗口的时间长度可以配置为小于5ms。
或者，所述目标时间窗口对应的时间单元的个数小于所述目标发送周期对应的时间单元的总个数。
这里，网络设备在上述目标时间窗口内发送目标SS/PBCH，终端在该目标时间窗口内接收目标SS/PBCH，由于该目标时间窗口对应的时间长度小于同步广播信号块SS/PBCH的发送周期，从而使得终端能够在寻呼时机之前的较短时间内完成同步和/或时频跟踪，进而降低了终端的功耗。
进一步地，在上述步骤301在目标时间窗口内，发送目标同步广播信号块SS/PBCH之前，所述信息传输方法还包括：
获取终端的节能配置信息；在所述节能配置信息指示终端支持节能配置的情况下，发送所述目标同步广播信号块SS/PBCH。
上述终端的节能配置信息用于指示终端是否支持节能配置。
具体的，上述获取终端的节能配置信息包括：
网络设备获取终端上报的节能配置信息，或者，获取网络设备为所述终端配置的节能配置信息。
这里，上述节能配置信息可以由网络静态或半静态配置，也可以由网络通过DCI动态指示。
进一步地，上述步骤301在目标时间窗口内，发送目标同步广播信号块SS/PBCH之后，所述信息传输方法还包括：
在所述寻呼时机发送寻呼消息。
进一步地，上述步骤301在目标时间窗口内，发送目标同步广播信号块SS/PBCH，包括：
在所述目标时间窗口内的第一时刻，开始发送所述目标同步广播信号块SS/PBCH，所述第一时刻为所述目标时间窗口内的第一时间单元对应的时刻，且所述第一时刻为所述目标时间窗口的起始时刻或位于所述起始时刻之后的时刻。
可选的，该第一时间单元可具体为目标时间窗口内的第一个时间单元， 该第一时间单元具体为计数器、时隙、子帧、正交频分复用(Orthogonal Frequency Division Multiplexing，OFDM)符号、循环前缀正交频分复用(Cyclic Prefix-OFDM，CP-OFDM)符号或离散傅里叶变换扩频的正交频分复用(Discrete Fourier Transform-Spread-OFDM，DFT-s-OFDM)符号。可选的，上述第一个时间单元为第一个时隙。
另外，所述目标广播信号块SS/PBCH发送完成的第二时刻为所述目标时间窗口的结束时刻或位于所述结束时刻之前的时刻；
所述目标时间窗口的结束时刻所在的第二时间单元与所述寻呼时机所在的第三时间单元相同；
或者，所述目标时间窗口的结束时刻所在的第二时间单元位于所述寻呼时机所在的第三时间单元之前。
这里，上述第二时间单元为计数器、时隙、子帧、正交频分复用OFDM符号、循环前缀正交频分复用CP-OFDM符号或离散傅里叶变换扩频的正交频分复用DFT-s-OFDM符号；
上述第三时间单元为计数器、时隙、子帧、正交频分复用OFDM符号、循环前缀正交频分复用CP-OFDM符号或离散傅里叶变换扩频的正交频分复用DFT-s-OFDM符号。
需要说明的是，第二时间单元和第三时间单元的时间粒度相同，例如，如果第二时间单元为时隙，则第三时间单元也为时隙；如果第二时间单元为OFDM符号，则第三时间单元也为OFDM符号。
进一步地，所述目标同步广播信号块SS/PBCH在所述目标时间窗口内占用N个连续的或非连续的时间单元，N为正实数。
上述时间单元可具体为时隙，如图4所示，可在目标时间窗口内发送一个时隙的目标SS/PBCH，也可在目标时间窗口内发送多个时隙的目标SS/PBCH。
具体的，在上述时间单元为时隙时，目标SS/PBCH可在所述目标时间窗口内占用N个连续的时隙，在上述时间单元为OFDM符号时，目标SS/PBCH可在所述目标时间窗口内占用N个非连续的OFDM符号。
或者，如果没有多个波束配置，则目标SS/PBCH可在所述目标时间窗口 内占用N个连续的时间单元，如果有多个波束配置，则目标SS/PBCH可在所述目标时间窗口内占用N个连续的或者非连续的时间单元。
或者，如果子载波间隔SCS小于或等于30KHz时，则目标SS/PBCH可在所述目标时间窗口内占用N个连续的时间单元；如果子载波间隔SCS大于30KHz时，则目标SS/PBCH可在所述目标时间窗口内占用N个非连续的时间单元。
另外，在目标SS/PBCH可在所述目标时间窗口内占用N个连续的时隙时，每个slot内的目标同步广播信号块的时频位置可以和NR R15的SS/PBCH的时频位置相同，也可以是基站配置的；所述N个连续的slot的总的发送时长小于或者等于所述目标时间窗口的时间长度。
这里，N可以是基站和UE根据提前约定的规则确定的，可以是基站配置的，可以是UE自己决定的，也可以是UE自己决定后通知给基站的，其他确定N的方法本公开实施例不做具体限定。其中，N可以是静态、半静态或动态配置的、或者通过基站和UE预定义，或者通过RRC信令配置，或者MAC CE(控制单元)静态或半静态配置，也可以是通过DCI动态配置的。
具体的，N是由网络设备根据终端的同步状态、终端所处的小区位置和/或终端所处位置的干扰强度配置的；
或者，N是协议预先约定的；
或者，N是由终端确定后并通知给所述网络设备的。
其中，所述时间单元包括：计数器、时隙、子帧、正交频分复用OFDM符号、循环前缀正交频分复用CP-OFDM符号或离散傅里叶变换扩频的正交频分复用DFT-s-OFDM符号。
作为第一种可选的实现方式，根据终端的同步状态配置N的取值，该实现方式可具体包括：
如果终端处于非同步状态，则N的取值可以大于1，例如N＝3，用于尽快完成同步和时频跟踪；上述N个时间单元可以是连续的也可以是非连续的，如果基站配置了多波束，则根据所述目标时间窗口的大小和波束的个数，配置N的取值。
如果终端处于同步状态，则N的取值可以配置成1。
作为第二种可选的实现方式，根据终端所处位置的干扰强度配置N的取值，该实现方式可具体包括：
如果终端处于强干扰环境，且UE的无线资源管理RRM测量量，例如，接收信号的强度指示RSSI高于或等于第一门限，所述第一门限为实数，或者参考信号接收质量RSRQ低于或等于第二门限，所述第二门限为实数，则所述N的取值可以配置为大于1的实数，例如N＝3，用于提高同步精度和提高时频跟踪精度。如果UE测量RSSI低于或等于第二门限，则所述N的取值可以配置为1，所述第二门限小于或等于第一门限。
作为第三种可选的实现方式，根据终端所处的小区位置配置N的取值，该实现方式可具体包括：
如果所述UE处于小区边缘位置，例如，UE测量的信号与干扰加噪声比SINR低于或等于第三门限，所述第三门限为实数，或者RSRQ低于或等于第四门限，所述第四门限为实数，或者RSRP低于或等于第五门限，所述第五门限为实数，则所述N的取值可以配置为大于1的实数，例如N＝3；如果所述UE测量的SINR高于或等于第五门限，则N的取值可以等于1。所述第五门限大于或等于第三门限。
需要说明的是，如果基站需要同时配置多个UE的N的取值，则基站可以给多个UE配置一个N值，也可以给每个UE配置不同的N值，具体的，取决于基站的算法实现。
