请参考图1，其示出了本公开实施例提供的一种无线通信系统的结构示意图。如图1所示，无线通信系统是基于移动通信技术的通信系统，该无线通信系统可以包括：若干个用户设备110以及若干个基站120。
其中，用户设备110可以是指向用户提供语音和/或数据连通性的设备。用户设备110可以经无线接入网(Radio Access Network，RAN)与一个或多个核心网进行通信，用户设备110可以是物联网用户设备，如传感器设备、移动电话和具有物联网用户设备的计算机，例如，可以是固定式、便携式、袖珍式、手持式、计算机内置的或者车载的装置。例如，站(Station，STA)、订户单元(subscriber unit)、订户站(subscriber station)，移动站(mobile station)、移动台(mobile)、远程站(remote station)、接入点、远程用户设备(remote terminal)、接入用户设备(access terminal)、用户装置(user terminal)、用户代理(user agent)、用户设备(user device)、或用户设备(user equipment)。或者，用户设备110也可以是无人飞行器的设备。或者，用户设备110也可以是车载设备，比如，可以是具有无线通信功能的行车电脑，或者是外接行车电脑的无线用户设备。或者，用户设备110也可以是路边设备，比如，可以是具有无线通信功能的路灯、信号灯或者其它路边设备等。
基站120可以是无线通信系统中的网络侧设备。其中，该无线通信系统可以是第四代移动通信技术(the 4th generation mobile communication，4G)系统，又称长期演进(Long Term Evolution，LTE)系统；或者，该无线通信系统也可以是5G系统，又称新空口系统或5G NR系统。或者，该无线通信系统也可以是5G系统的再下一代系统。其中，5G系统中的接入网可以称为NG-RAN(New Generation-Radio Access Network，新一代无线接入网)。
其中，基站120可以是4G系统中采用的演进型基站(eNB)。或者，基站120也可以是5G系统中采用集中分布式架构的基站(gNB)。当基站120采用集中分布式架构时，通常包括集中单元(central unit，CU)和至少两个分布单元(distributed unit，DU)。集中单元中设置有分组数据汇聚协议(Packet Data Convergence Protocol，PDCP)层、无线链路层控制协议(Radio Link Control，RLC)层、媒体访问控制(Media Access Control，MAC)层的协议栈；分布单元中设置有物理(Physical，PHY)层协议栈，本公开实施例对基站120的具体实现方式不加以限定。
基站120和用户设备110之间可以通过无线空口建立无线连接。在不同的实施方式中，该无线空口是基于第四代移动通信网络技术(4G)标准的无线空口；或者，该无线空口是基于第五代移动通信网络技术(5G)标准的无线空口，比如该无线空口是新空口；或者，该无线空口也可以是基于5G的更下一代移动通信网络技术标准的无线空口。

为了便于本领域内技术人员理解，本公开实施例列举了多个实施方式以对本公开实施例的技术方案进行清晰地说明。当然，本领域内技术人员可以理解，本公开实施例提供的多个实施例，可以被单独执行，也可以与本公开实施例中其他实施例的方法结合后一起被执行，还可以单独或结合后与其他相关技术中的一些方法一起被执行；本公开实施例并不对此作出限定。
为了更好地理解本公开任一个实施例所描述的技术方案，首先，对相关技术中的终端与网络之间同步的场景进行说明：
在一个实施例中，在无线资源控制(RRC，Radio Resource Control)空闲态下，可以使用附加的时频跟踪参考信号(TRS，Tracking Reference Signal)或者小区参考信号(CRS，Cell Reference Signal)来辅助终端进行终端与网络之间的时频域同步，相较于SSB同步，TRS或CRS的配置可以配置得离PO时刻更近，而原来的SSB是离PO位置较远的。因此，终端需要提前很久醒过来和SSB同步。而采用了附加的TRS或者CRS之后，则可以更晚醒过来，因此，可以更加省电。
在一个实施例中，可以在系统消息中广播附加的TRS或者CRS的配置信息，以及TRS或者CRS是否在广播的可用状态信息。TRS/CRS的配置信息可以认为和可用状态信息是分别指示的。即网络可能配置了TRS/CRS，但是并没有进行实际传输。也就是说，并没有给处于RRC空闲态的终端使用。
在一个实施例中，TRS或者CRS是否在广播的状态信息都是需要通知处于RRC非连接态的终端的，因为终端需要根据有效的TRS或者CRS的信息来决定如何进行和网络的同步。若二者不一致则会带来较大的问题。例如，网络是在发送有效的TRS或者CRS信息的，若终端认为没有，则终端就会采用原来同步SSB的方式进行同步，会造成较大耗电；反之，若网络是停止发送有效的TRS或者CRS信息的，若终端还是按原有的方式去进行同步，则会造成同步精度下降。
在一个实施例中，可以是通过系统消息更新的方式或者采用寻呼下行控制信息DCI或者寻呼提前指示PEI的方式通知用户。无论是何种方式，因为都需要发送寻呼DCI，而不同用户的PO是根据UE ID取模计算出来的，因此，不可能所有的终端在同样的时间点都同时收到基站的指示。
在一个实施例中，请参见图2，如果TRS或者CSI-RS的可用性变更的周期复用了系统消息变更的周期，则会存在如下问题：网络需要在特定的时间边界进行可用性变更。假设该特定的时间边界为系统消息修改边界(T2)。若在系统消息修改边界之前(T1)连接态用户都突然切换走了，则导致从T1时 刻开始，此时没有TRS或者CRS资源了。而终端的配置需要在T2时刻更新，但是终端在T1之后的PO位置，还在使用原来的TRS或者CSI-RS的方式在进行同步去获取寻呼DCI(图中举例是3个在不同位置的PO的用户)，导致监听不到寻呼DCI，因此，导致此后都在使用错误的TRS或者CSI-RS在同步，但是事实上网络已经关闭了TRS或者CSI-RS。
在一个实施例中，假设网络中同时存在非连续接收周期DRX用户和配置有增强非连续接收周期eDRX用户。对于DRX用户而言，其DRX周期会小于系统消息变更的周期，因此一定会在系统消息变更的周期内收到寻呼消息。但是，对于eDRX的用户而言，其系统消息更新边界为256SFN，即每间隔2.56s。此时若网络按照eDRX更新边界进行TRS/CRS资源可用性更新，则意味着网络需要一直保持TRS/CRS资源发送，直到通知完eDRX的用户，即允许的更新边界点为2.56s。在一个实施例中，采用两套TRS或者CRS资源，一套用于DRX用户，而一套用于eDRX用户，后者需要在eDRX的更新边界进行更新。这样的话，两套TRS/CRS的发送会带来一个资源的浪费。
如图3所示，本实施例中提供一种终端与网络同步的方法，其中，该方法由终端执行，该方法包括：
步骤31、基于是否接收到可用性指示信息的结果，确定同步参考信号的可用性状态；
其中，可用性指示信息至少指示：同步参考信号的状态为可用状态或者为不可用状态；同步参考信号用于处于无线资源控制RRC非连接态的终端与网络之间的同步。
这里，本公开所涉及的终端可以是但不限于是手机、可穿戴设备、车载终端、路侧单元(RSU，Road Side Unit)、智能家居终端、工业用传感设备和/或医疗设备等。这里，处于RRC非连接态的终端可以是处于RRC空闲态的终端或者是处于RRC非激活态的终端。这里，终端可以是寻呼的寻呼监听周期大于设置阈值的终端。
本公开中涉及的基站可以是终端接入网络的接入设备。这里，基站可以为各种类型的基站，例如，第三代移动通信(3G)网络的基站、第四代移动通信(4G)网络的基站、第五代移动通信(5G)网络的基站或其它演进型基站。
在一个实施例中，同步参考信号，包括时频跟踪参考信号TRS和信道状态信息参考信号CSI-RS中的至少之一。需要说明的是，同步参考信号也可以是其他可以用于终端和网络之间同步的参考信号，在此不做限定。
在一个实施例中，可用性指示信息可以是用于指示同步参考信号的状态从可用状态切换至不可用状态的信息；或者，可用性指示信息也可以是用于指示同步参考信号的状态从不可用状态切换至可用状态的信息。
示例性地，可以是通过显性方式指示可用性状态。例如，如果可用性指示信息的预定信息域指示第一值，同步参考信号的状态为可用状态；或者，如果可用性指示信息的预定信息域指示第二值，同步参考信号的状态为不可用状态。
示例性地，也可以是通过隐性方式指示可用性状态。例如，如果消息携带可用性指示信息的预定信息域，同步参考信号的状态为可用状态；或者，如果消息未携带可用性指示信息的预定信息域，同步参考信号的状态为不可用状态。
在一个实施例中，可以是基站配置同步参考信号的配置信息。这里，配置信息至少指示传输同步参考信号的时域和/或频域信息。基站可以是根据是否广播同步参考信号的确定结果确定可用性指示信息。示例性地，如果基站在广播同步参考信号，可用性指示信息指示同步参考信号的状态为可用状态，或者，如果基站未广播同步参考信号，可用性指示信息指示同步参考信号的状态为不可用状态。需要说明的是，是否广播同步参考信号可以是基站确定的。
在一个实施例中，基站向终端发送可用性指示信息；响应于终端接收到可用性指示信息，终端根据可用性指示信息确定同步参考信号的可用性状态，或者，响应于终端未接收到可用性指示信息，终端根据预定方式确定同步参考信号的可用性状态。这里，预定方式可以是区别于根据可用性指示信息确定同步参考信号的可用性状态的方式。例如，可以是根据系统消息中携带的信息确定同步参考信号的可用性状态的方式，在此不做限定。
在一个实施例中，响应于终端接收到可用性指示信息且可用指示信息指示同步参考信号的可用性状态为可用状态，终端确定同步参考信号为可用状态；或者，响应于终端接收到可用性指示信息且可用指示信息指示同步参考信号的可用性状态为不可用状态，终端确定同步参考信号为不可用状态。这里，在同步参考信号为可用状态时，终端可以基于同步参考信号执行终端与网络之间的同步。需要说明的是，在同步参考信号为不可用状态时，终端不可以基于同步参考信号执行终端与网络之间的同步。
在一个实施例中，在终端未接收到可用性指示信息时，终端可以根据基于SSB的同步方式进行网络与终端之间的同步。或者，在终端接收到可用性指示信息且可用性指示信息指示同步参考信号为不可用状态时，终端可以根据基于SSB的同步方式进行网络与终端之间的同步。如此，能够适应于不同的网络场景。
在一个实施例中，在终端未接收到可用性指示信息时，终端可以根据第一方式确定的同步参考信号的状态进行网络与终端之间的同步，其中，第一方式为基于预定配置状态确定可用性状态的方式。这里，预定配置状态可以被预先配置为可用状态或者不可用状态。需要说明的是，终端根据第一方式进行网络与终端之间的同步之前，需要接收到同步参考信号的配置信息。
在一个实施例中，在终端未接收到可用性指示信息时，终端可以根据第二方式确定的同步参考信号的状态进行网络与终端之间的同步，其中，第二方式为基于系统消息确定可用性状态的方式。这里，可以是系统消息携带可用性状态的指示信息，该指示信息可以指示同步参考信号为可用状态或者不可用状态。这里，如前述，系统消息可以通过显性方式或者隐性方式指示可用性状态的指示信息，在此不做限定。在一个实施例中，系统消息还可以携带同步参考信号的配置信息。
在一个实施例中，响应于接收到可用性指示信息，根据可用性指示信息确定同步参考信号的可用性状态。在终端基于接收到的可用性指示信息确定同步参考信号的可用性状态后，可以在根据更新周期确定的某个预定时间点更新同步参考信号的可用性状态。作为一种实施例，更新周期为小区默认的DRX寻呼周期。在一个实施例中，在预定时间点更新同步参考信号的可用性状态可以是在接收到可用性指示信息的更新周期的起点更新同步参考信号的可用性状态。
在一个实施例中，响应于接收到可用性指示信息，根据可用性指示信息确定同步参考信号的可用性状态。在确定同步参考信号的可用性状态后，立即生效可用性指示信息指示的可用性状态。或者，响应 于接收到可用性指示信息，根据可用性指示信息确定同步参考信号的可用性状态。在确定同步参考信号的可用性状态后，在下一个DRX周期生效可用性指示信息指示的可用性状态。
在一个实施例中，响应于接收到可用性指示信息，根据可用性指示信息确定同步参考信号的可用性状态。在达到更新周期的边界时，生效可用性指示信息指示的可用性状态；其中，更新周期用于更新同步参考信号的可用性状态。这里，更新周期可以与系统消息的变更周期相同。
需要说明的是，可用性状态的更新可以是不同于可用性状态的生效的过程。可用性状态被更新并不代表可用性状态已经生效。只有在可用性状态已经生效后，才可以基于同步参考信号执行终端与网络之间的同步。
在一个实施例中，如果终端的寻呼监听周期大于更新周期，确定不能接收到可用性指示信息，此时，终端基于预定方式确定同步参考信号的可用性状态。或者，如果无线通信质量小于信号质量阈值，确定不能接收到可用性指示信息，此时，终端基于预定方式确定同步参考信号的可用性状态。这里，预定方式，可以包括：第一方式，基于预定配置状态确定可用性状态的方式；和/或，第二方式，基于系统消息确定可用性状态的方式。
在一个实施例中，终端不能接收到可用性指示信息可能是：尝试解码，但是，因为信号质量原因导致解码失败。
在一个实施例中，终端不能接收到可用性指示信息可能是：从信号覆盖范围外到信号覆盖范围内(out of coverage到return to coverage)。需要说明的是，在本公开中，终端不能接收到可用性指示信息的原因不做具体限定，包括各种导致不能接收到可用性指示信息的情况。
在一个实施例中，如果终端的寻呼监听周期小于更新周期，确定能够接收到可用性指示信息，此时，可以根据可用性指示信息确定同步参考信号的可用性状态。
作为一种实施例，更新周期为小区默认的DRX寻呼周期。
需要说明的是，本公开中术语“大于”也涵盖了“大于等于”的含义，“小于”也涵盖了“小于等于”的含义。
在本公开实施例中，基于是否接收到可用性指示信息的结果，确定同步参考信号的可用性状态；其中，可用性指示信息至少指示：同步参考信号的状态为可用状态或者为不可用状态；同步参考信号用于处于无线资源控制RRC非连接态的终端与网络之间的同步。这里，由于同步参考信号的可用性状态是根据处于RRC非连接态的终端是否接收到可用性指示信息的结果确定的，相较于处于RRC非连接态的终端在接收到和未接收到可用性指示信息的情况下都是基于单一方式确定同步参考信号的可用性状态的方式，可以适应于可用性指示信息的接收情况，使得终端与网络之间的同步更加可靠和精确。
需要说明的是，本领域内技术人员可以理解，本公开实施例提供的方法，可以被单独执行，也可以与本公开实施例中一些方法或相关技术中的一些方法一起被执行。
如图4所示，本实施例中提供一种终端与网络同步的方法，其中，该方法由终端执行，该方法包括：
步骤41、响应于接收到可用性指示信息，根据可用性指示信息确定同步参考信号的可用性状态。
在一个实施例中，如果终端的寻呼监听周期小于更新周期，确定能够接收到可用性指示信息，此时， 可以根据可用性指示信息确定同步参考信号的可用性状态。
在一个实施例中，响应于接收到可用性指示信息且可用指示信息指示同步参考信号的可用性状态为可用状态，确定同步参考信号为可用状态；或者，响应于接收到可用性指示信息且可用指示信息指示同步参考信号的可用性状态为不可用状态，确定同步参考信号为不可用状态。
在一个实施例中，响应于接收到可用性指示信息，根据可用性指示信息确定同步参考信号的可用性状态。在确定同步参考信号的可用性状态后，可以立即生效可用性指示信息指示的可用性状态；或者，在确定同步参考信号的可用性状态后，可以在下一个DRX周期生效可用性指示信息指示的可用性状态。
这里，在可用性状态被生效后，就可以基于生效后的可用性状态执行终端与网络之间的同步。在一个实施例中，在终端接收到可用性指示信息且可用性指示信息指示同步参考信号为不可用状态时，终端可以根据基于SSB的同步方式进行网络与终端之间的同步。

在一个实施例中，可以是根据无线通信质量确定更新周期。示例性地，响应于无线通信质量大于质 量阈值，更新周期大于周期阈值；或者，响应于无线通信质量小于质量阈值，更新周期小于周期阈值。如此，更新周期可以适应于无线通信质量。
在一个实施例中，在按照更新周期更新同步参考信号的可用性状态后，终端并不能基于该可用性状态立即执行终端与网络之间的同步，还需要生效该可用性状态。只有在生效该可用性状态后，终端才能够执行终端与网络之间的同步。
在一个实施例中，更新周期与系统消息的变更周期相同。
在一个实施例中，更新周期为小区默认的DRX寻呼周期。
需要说明的是，本领域内技术人员可以理解，本公开实施例提供的方法，可以被单独执行，也可以与本公开实施例中一些方法或相关技术中的一些方法一起被执行。

在一个实施例中，可以是根据无线通信质量确定更新周期。示例性地，响应于无线通信质量大于质量阈值，更新周期大于周期阈值；或者，响应于无线通信质量小于质量阈值，更新周期小于周期阈值。如此，更新周期可以适应于无线通信质量。
需要说明的是，本领域内技术人员可以理解，本公开实施例提供的方法，可以被单独执行，也可以与本公开实施例中一些方法或相关技术中的一些方法一起被执行。
