本申请涉及通信领域，并且更具体地，涉及一种无线通信方法和设备。
背景技术
在长期演进(Long Term Evolution，简称为“LTE”)系统中，终端设备可以对基站发送的参考信号进行测量，以获取小区的信号质量。
终端设备可以根据该小区的信号质量，是否触发小区切换。
在未来的5G系统中，如何判断小区的信号质量是一项亟待解决的问题。
发明内容
本申请实施例提供一种无线通信方法和设备，可以根据小区中发送的多个同步信号块中的至少一个同步信号块的测量结果，进行小区的信号质量的判断，实现了5G系统中的小区的信号质量的判断。
第一方面，提供了一种无线通信方法，包括：
终端设备针对第一小区中发送的多个同步信号块中的至少一个同步信号块，进行测量；
根据测量结果，所述终端设备确定所述第一小区对应的信号质量。
因此，在本申请实施例中，可以根据小区中发送的多个同步信号块中的至少一个同步信号块的测量结果，进行小区的信号质量的判断，实现了5G系统中的小区的信号质量的判断。
结合第一方面，在第一方面的一种可能的实现方式中，所述多个同步信号块中每个同步信号块分别占用不同的频域资源。
结合第一方面或其上述任一种可能的实现方式，在第一方面的另一种可能的实现方式中，所述第一小区包括所述终端设备当前的服务小区和/或为所述终端设备的邻小区。
结合第一方面或其上述任一种可能的实现方式，在第一方面的另一种可能的实现方式中，所述方法还包括：
所述终端设备接收所述网络设备发送的指示信息，所述指示信息用于指示待测量的所述至少一个同步信号块。
结合第一方面或其上述任一种可能的实现方式，在第一方面的另一种可能的实现方式中，所述第一小区为所述终端设备当前的服务的小区，所述至少一个同步信号块为所述终端设备进行同步的同步信号块。
基于该种实现方式，由于仅需要根据终端设备进行同步的同步信号块进行测量，需要测量的同步信号块的数量较少，终端设备的负担较轻。
结合第一方面或其上述任一种可能的实现方式，在第一方面的另一种可能的实现方式中，所述至少一个同步信号块为所述第一小区中的所有同步信号块。
基于该种实现方式，终端设备可以对第一小区的所有同步信号块进行测量，可以综合所有同步信号块的测量结果，确定第一小区对应的信号质量。
针对该种实现方式，如果第一小区为终端设备的当前服务小区，如果本成员载波上存在部分频率资源上信号质量较好，则终端设备不需要触发上报事件，减少了终端设备切换到其他小区的概率，可以实现尽可能利用本小区的不同频率资源来服务好用户。
结合第一方面或其上述任一种可能的实现方式，在第一方面的另一种可能的实现方式中，所述至少一个同步信号块为所述终端设备的工作带宽内的所有同步信号块。
基于该种实现方式，可以避免终端设备测量自身工作带宽外的SS block，可以避免终端设备在不同的频率资源上的过多测量，因为在终端设备进行测量时，需要将终端设备调谐到相应的频率资源上才可能测量，处理较为复杂。
结合第一方面或其上述任一种可能的实现方式，在第一方面的另一种可能的实现方式中，所述至少一个同步信号块为配置的同步信号块集合中的所有同步信号块。
具体地，可以预配置(出厂预配置或网络设备预配置)带宽成员载波内一个同步信号块集合中的同步信号块进行测量，该同步信号块集合包括同步信号块可以根据实际情况改变。该同步信号块集合可以包括小区内的全部或部分同步信号块。
结合第一方面或其上述任一种可能的实现方式，在第一方面的另一种可能的实现方式中，所述根据测量结果，所述终端设备确定所述第一小区对应的信号质量，包括：

该无线通信系统100还包括位于网络设备110覆盖范围内的至少一个终端设备120。终端设备120可以是移动的或固定的。可选地，终端设备120可以指接入终端、用户设备(User Equipment，UE)、用户单元、用户站、移动站、移动台、远方站、远程终端、移动设备、用户终端、终端、无线通信设备、用户代理或用户装置。接入终端可以是蜂窝电话、无绳电话、会话启动协议(Session Initiation Protocol，SIP)电话、无线本地环路(Wireless Local Loop，WLL)站、个人数字处理(Personal Digital Assistant，PDA)、具有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、车载设备、可穿戴设备、未来5G网络中的终端设备或者未来演进的PLMN中的终端设备等。

可选地，5G系统或网络还可以称为新无线(New Radio，NR)系统或网络。
图1示例性地示出了一个网络设备和两个终端设备，可选地，该无线通信系统100可以包括多个网络设备并且每个网络设备的覆盖范围内可以包括其它数量的终端设备，本申请实施例对此不做限定。

应理解，本文中术语“系统”和“网络”在本文中常被可互换使用。本文中术语“和/或”，仅仅是一种描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B这三种情况。另外，本文中字符“/”，一般表示前后关联对象是一种“或”的关系。
图2是根据本申请实施例的无线通信方法200的示意性流程图。该方法200可选地可以应用于图1所示的系统，但并不限于此。如图2所示，该方法200包括以下至少部分内容。
在210中，终端设备针对第一小区中发送的多个同步信号块中的至少一个同步信号块，进行测量。
可选地，本申请实施例的小区可以等价于载波(成员载波)。
可选地，在本申请实施例中，所述多个同步信号块(Synchronization Signal Block，SSB)中每个同步信号块分别占用不同的频域资源。同步信号块之间的频域资源可选地不重叠。
对于5G系统，可以支持带宽很大的宽带成员载波，例如带宽为400MHz甚至1GHz的宽带成员载波。对于具备非常大的带宽的宽带成员载波，其不同的频率位置的传播特性可能会有较大的差异。例如宽带成员载波的高频段处与低频段处的路损等方面会有较大的差异。基于此，可以在带宽成员载波内，发送多个SS Block。
对于终端设备，由于不同的使用场景以及不同的成本考虑，在同一个系统宽带成员载波内，会分布具备多种工作带宽的终端，例如系统带宽为400MHz，则可能分布有400MHz的带宽的终端，还可能有100MHz、40MHz、10MHz带宽的终端设备。这样，如果在系统宽带成员载波内仅存在一个SS block位置，则具有较小工作带宽的终端在其工作带宽内可能不存在SS block，因此，可以增加发送的SS Block的位置，使得终端设备的工作带宽或附近存在SS Block的机率增加。其中，终端设备在需要接收SS block以进行时频同步、无线资源管理(Radio Resource Management，RRM)测量以及读取物理广播信道(Physical Broadcasting Channel，PBCH)时，可以调频到SS block所在的频率位置。
在5G系统中，网络设备可以向终端设备发送包含多个同步信号块 (Synchronization Signal block)的SS burst set，每一个SS block(SSB)内包含主同步信号(Primary Synchronization Signal，PSS)、辅同步信号(Secondary Synchronization Signal，SSS)、物理广播信道(Physical Broadcasting Channel，PBCH)。且SS block在系统带宽内的频率位置不限定于系统带宽的中心频点位置。例如，如图3所示，在带宽成员载波的带宽内，可以发送SSB1，SSB2，SSB3和SSB4，该4个SSB可以占有不同的频域资源。
可选地，在本申请实施例中，所述第一小区为所述终端设备当前的服务小区或为所述终端设备的邻小区。其中，该邻小区可以与终端设备所属的服务小区属于同网络(例如，均为NR系统)或者，属于不同的网络(例如，服务小区为NR系统，邻小区属于LTE系统)。
可选地，在本申请实施例中，网络设备可以向终端设备发送指示信息，该指示信息用于指示待测量的至少一个同步信号块，终端设备可以根据网络设备发送的指示信息，在相应的同步信号块上进行测量。
可选地，在本实施例中，也可以在终端设备上预设(出厂预设)需要测量的同步信号块，无需网络设备的指示。
在220中，根据测量结果，所述终端设备确定所述第一小区对应的信号质量。
可选地，本申请实施例提到的测量结果可以包括信号强度，例如，参考信号接收功率(Reference Signal Receiving Power，RSRP)，或者，类似于RSRP的信号强度；和/或，包括信号与干扰的关系值，例如，参考信号接收质量(Reference Signal Receiving Quality，RSRQ)，信号与干扰加噪声比(Signal to Interference plus Noise Ratio，SINR)，或者，类似于RSRQ或SINR的值。
可选地，在测量的同步信号块包括多个同步信号块时，对测量的所述多个同步信号块的测量结果进行处理，以确定所述第一小区对应的信号质量。
具体地说，对测量的所述多个同步信号块的测量结果进行平均处理，以确定所述第一小区对应的信号质量。其中，该处理可以是算数平均处理，也可以是加权平均处理。
可选地，在本申请实施例中，在测量的同步信号块包括多个同步信号块时，将测量的所述多个同步信号块的测量结果中的信号质量最好的结果或信 号质量最差的结果，确定为所述第一小区对应的信号质量。
在一种实现方式中，所述第一小区为所述终端设备当前的服务的小区，测量的所述至少一个同步信号块为所述终端设备进行同步的同步信号块。
基于该种实现方式，由于仅需要根据终端设备进行同步的同步信号块进行测量，需要测量的同步信号块的数量较少，终端设备的负担较轻。
在终端设备对进行同步的同步信号块进行测量时，该测量的同步信号块仅有一个，可以将一个同步信号的测量结果，确定为第一小区对应的信号质量。
在一种实现方式中，测量的所述至少一个同步信号块为所述第一小区中的所有同步信号块。
基于该种实现方式，终端设备可以对第一小区的所有同步信号块进行测量，可以综合所有同步信号块的测量结果，确定第一小区对应的信号质量。
针对该种实现方式，如果第一小区为终端设备的当前服务小区，如果本成员载波上存在部分频率资源上信号质量较好，则终端设备不需要触发上报事件，减少了终端设备切换到其他小区的概率，可以实现尽可能利用本小区的不同频率资源来服务好用户。
在一种实现方式中，测量的所述至少一个同步信号块为所述终端设备的工作带宽内的所有同步信号块。
具体地，终端设备可以在自身的工作带宽上检测到的同步信号块进行测量。
例如，从网络侧看1个成员载波是400MHz，每100MHz含有1个SS block，UE自己带宽200MHz，对应成员载波的低频的200MHz，涵盖了2个SS block，则就测量这2个SS block。
基于该种实现方式，可以避免终端设备测量自身工作带宽外的SS block，可以避免终端设备在不同的频率资源上的过多测量，因为在终端设备进行测量时，需要将终端设备调谐到相应的频率资源上才可能测量，处理较为复杂。
在一种实现方式中，所述至少一个同步信号块为配置的同步信号块集合中的所有同步信号块。
具体地，可以预配置(出厂预配置或网络设备预配置)带宽成员载波内一个同步信号块集合中的同步信号块进行测量，该同步信号块集合包括同步信号块可以根据实际情况改变。该同步信号块集合可以包括小区内的全部或 部分同步信号块。
可选地，在本申请实施例中，在所述第一小区对应的信号质量满足第一触发条件时，执行与所述第一触发条件相对应的操作。
在一种实现方式中，所述第一触发条件相对应的操作是启动上报指示所述第一小区对应的信号质量的信息。
例如，在第一小区为终端设备的当前服务小区时，如果第一小区对应的信号质量差于一定值，则终端设备可以启动上报指示第一小区对应的信号质量的信息，以便于网络设备可以根据该信息，确定是否对终端设备进行小区切换。
例如，在第一小区为终端设备的相邻小区时，如果第一小区对应的信号质量优于一定值，则终端设备可以启动上报指示第一小区对应的信号质量的信息，以便于终端设备可以根据该信息，确定是否对终端设备进行小区切换。
例如，在第一小区包括终端设备的当前服务小区和相邻小区时，如果当前服务的小区对应的信号质量差于一定值，且终端设备的邻小区的信号质量由于一定值，则终端设备可以启动上报指示该当前服务小区和相邻小区的信号质量的信息，以便于终端设备可以根据该信息，确定是否对终端设备进行小区切换。
在一种实现方式中，所述第一触发条件相对应的操作是：针对第二小区中发送的同步信号块和/或参考信号进行测量，和/或启动上报指示所述第二小区对应的信号质量的信息，其中，所述第二小区对应的信号质量是通过针对第二小区中发送的同步信号块和/或参考信号进行测量得到的。
例如，在第一小区为终端设备的当前服务小区时，如果第一小区对应的信号质量差于一定值，则终端设备可以对相邻小区的同步信号块和/或参考信号进行测量和/或启动上报指示该相邻小区对应的信号质量的信息，为后续可能的小区切换做准备。
例如，在第一小区为终端设备的相邻小区时，如果第一小区对应的信号质量差于一定值，则终端设备可以对其他相邻小区的同步信号块和/或参考信号进行测量和/或启动上报指示该其他相邻小区对应的信号质量的信息，为后续可能的小区切换做准备。
可选地，本申请实施例中提到的参考信号可以是信道状态信息参考信号(Channel State Information Reference Signal，CSI-RS)或下行小区专用信号 (Cell-Specific Reference Signal，CRS)。
可选地，该第二小区可以与第一小区同网络或异网络。
为了便于理解，以下将结合几种事件进行描述。
事件A1(Serving becomes better than threshold)：表示服务小区信号质量高于一定门限，满足此条件的事件被上报时，网络设备可以停止异频/异系统测量。
事件A2(Serving becomes worse than threshold)：表示服务小区信号质量低于一定门限，满足此条件的事件被上报时，网络设备可以启动异频/异系统测量。
事件A3(Neighbour becomes offset better than serving)：表示同频邻区质量高于服务小区质量，满足此条件的事件被上报时，网络设备启动同频切换请求。
事件A4(Neighbour becomes better than threshold)：表示异频邻区质量高于一定门限量，满足此条件的事件被上报时，网络设备可以启动异频切换请求。

事件B1(Inter RAT neighbour becomes better than threshold)：表示异系统邻区质量高于一定门限，满足此条件事件被上报时，网络设备启动异系统切换请求。
事件B2(Serving becomes worse than threshold1 and inter RAT neighbour becomes better than threshold2)：表示服务小区质量低于一定门限并且异系统邻区质量高于一定门限。
为了更加清楚地理解上述事件，以下将结合A2和A3事件进行详细说明。
A2事件
A2事件的触发条件是：Ms+Hys＜Thresh；
A2事件的取消条件是：Ms-Hys＞Thresh；
其中，Ms是服务小区的测量结果；Hys为事件的迟滞参数.；Thresh是事件的触发阈值。
A3事件

其中，Mn是邻小区的测量结果；0fn是邻小区频率的特定偏差；Ocn邻小区的小区特定偏差；Ms当前服务小区测量值；Ofs是服务小区的频率特定偏差；Ocs是邻小区的小区特定偏差；Hys是该事件的迟滞参数。
应理解，本申请实施例的触发测量上报的事件还可以是其他事件，以上事件不应对本申请实施例构成特别的限定。
