技术领域
本申请涉及无线通信领域但不限于无线通信领域，尤其涉及一种小区信号质量确定方法、小区选择或重选方法、通信设备及存储介质。
背景技术
在无线通信系统中，利用无线信号进行通信。无线信号的载频的频率有高低之分。例如，对于5G通信，载频的频率范围在6至100Ghz的高频频段上。对于利用5G频谱资源的5G新载波(New Radio，NR)小区，可能都配置有多个载波，这样的小区信号质量是基于多个载波的载波质量确定的。在用户设备(User Equipment，UE)进行小区选择或重选时，需要考虑到小区的小区信号质量。
在现有技术中，发现UE可能频繁发生小区选择或重选，从而导致UE因小区选择或重选消耗大量的功耗，进而导致UE的待机时机长的问题。

具体实施方式
以下结合说明书附图及具体实施例对本申请的技术方案做进一步的详细阐述。
如图1所示，本实施例提供一种小区信号质量确定方法，应用于第一通信设备中，这里的第一通信设备可包括UE或基站，包括：
步骤S110：确定小区内波束质量超过质量门限的波束的波束个数；
步骤S120：根据所述波束个数，确定小区信号质量。
在一些实施例中，所述波束个数与所述小区信号质量正相关。
本实施例中提供的UE可为各种类型的UE，例如，手机、平板电脑或可穿戴设备等人携带的通信终端、车载终端和/或物联网终端等通信设备。
在步骤S110中会确定小区内波束质量超过质量门限的波束的波束质量，例如，通过波束测量可以检测到UE当前所在地理位置对应的小区发射的多个波束的波束质量。当所述第一通信设备为UE时，所述UE可为处于连接态的UE，优选可为处于去激活态的UE或空闲态的UE。
所述波束质量可为参考信号接收功率(Reference Signal Receiving Power，RSRP)、参考信号接收质量(Reference Signal Receiving Quality，RSRQ)或信号噪声干扰比(Signal to Interference plus Noise Ratio，SINR)等可以表征UE对小区当前发送的波束的波束质量。
在本实施例中，小区A发送了4个波束，UE1分别测量了这4个波束，其中，测量的两个波束的波束质量超过质量门限，这两个波束即为上述波束质量超过质量门限的波束。
在本实施例中，在计算小区信号质量时，会综合考虑波束质量超过质量门限的波束的波束质量及波束质量超过质量门限的波束的个数这两个参数。若所述波束个数与小区信号质量是正相关的，即表明，则波束质量超过质量门限的波束的个数与小区信号质量的变化方向是相同的。在一些实施例中，波束质量超过质量门限的波束的波束个数与小区信号质量的补偿值是正相关的，即，小区信号质量与所述补偿值是正相关的。
在本实施例中，在步骤S120中可包括：
根据波束质量超过质量门限的波束的波束质量确定第一质量参数；
根据波束质量超过质量门限的波束的波束个数确定第二质量参数；
结合所述第一质量参数及所述第二质量参数，确定小区信号质量。
在本实施例中，所述第一质量参数可为波束质量超过质量门限的波束的波束质量的线性平均。
假设波束质量超过所述质量门限的波束个数为K，则所述第二质量参数可为：K个波束质量超过质量门限的波束对应的质量调整值，该质量调整值与K的取值正相关。
小区信号质量，是决定于第一质量参数和第二质量参数这两个部分的。在一些实施例中，若两个小区的第一质量参数相同，则K越大，则所述小区信号质量就越大，若K越小，则所述小区信号质量越小。总之，波束质量超过质量门限的波束的波束个数(即K)与所述小区信号质量正相关。
所述小区信号质量越大，则该小区被UE重选的概率就越高。
总之，所述小区信号质量，用于所述UE进行小区选择或重选。
本申请实施例还提供一种小区选择或重选方法，所述方法可包括：
确定小区内波束的波束质量；
确定出波束质量超过质量门限的波束个数K；
结合波束质量超过质量门限的波束的波束质量和K计算小区信号质量；
根据所述小区信号质量，进行小区选择或重选。所述小区信号质量的大小K的大小正相关。
例如，根据所述小区信号质量，进行小区选择或重选，选择，包括：
选择小区信号质量高的小区为重选后驻留的小区。
在一些实施例中，如图2所示，所述步骤S120可包括：
步骤S121：计算波束质量超过质量门限的至少部分波束的波束质量的线性平均；例如，有N个波束的波束质量超过质量门限，则这里的波束质量超过质量门限的至少部分波束，可包括：这N个波束的波束质量，或，这N个波束中的S个波束的波束质量，所述S为小于N的正整数。
步骤S122：当K大于或等于数量门限N时，根据所述线性平均及第一补偿值，确定所述小区信号质量，其中，所述小区信号质量不小于所述线 性平均；
和/或，
步骤S123：当K小于N时，根据所述线性平均及第二补偿值，确定所述小区信号质量，其中，所述小区信号质量小于所述线性平均。
在本实施例中，所述线性平均相当于前述的第一质量参数，在一些实施例中，所述第一质量参数还可为波束质量超过质量门限的波束的波束质量的中位值，总之，不局限于所述线性平均。
当K大于或等于数量门限时，根据线性平均和第一补偿值，确定出所述小区信号质量，这样得到的小区信号质量，会大于所述线性平均。
若K小于数量门限，说明当前波束质量大于质量门限的波束的个数较少，为了降低UE选择对应的小区，会基于线性平均和第二补偿值得到一个小于线性平均的小区信号质量。
在一些实施例中，所述第一补偿值可为线性平均的正向补偿值，而所述第二补偿值可为线性平均中的负向补偿值。
在本实施例中，所述线性平均可为多个波束的波束质量的加权平均值。
在本实施例中引入了所述数量门限及波束个数来确定一个补偿值，该补偿值是为前述第一补偿值还是第二补偿值，取决与波束个数K与数量门限之间的关系，这样的话，确保小区信号质量与K的正相关。所述第一补偿值和所述第二补偿值可为前述的第二质量参数的一种。进一步地，结合线性平均和第一补偿值或第二补偿值，可以计算出最终的小区信号质量，可为UE的小区选择或重选提供参考参数。
在本实施例中，作为第二质量参数的第一补偿值和第二补偿值，是与数量门限相关的，而在一些实施例中，可仅与波束个数K自身相关。
在一些实施例中，所述步骤S122的可实现方式有多种，以下提供8种可选方式：
可选方式一：所述步骤S122可包括：
利用如下公式计算所述小区信号质量；
小区信号质量＝f(Qbeam1，Qbeam2，…，QbeamN)+(K-N) m*Qoffset1；
可选方式二：所述步骤S122可包括：
小区信号质量＝f(Qbeam1，Qbeam2，…，QbeamN)*(K/N) m*Qoffset1；
可选方式三：所述步骤S122可包括：
小区信号质量＝f(Qbeam1，Qbeam2，…，QbeamK)+(K-N) m*Qoffset1；
可选方式四：所述步骤S122可包括：
小区信号质量＝f(Qbeam1，Qbeam2，…，QbeamK)*(K/N) m*Qoffset1；
可选方式五：
小区信号质量＝f(Qbeam1，Qbeam2，…，QbeamN)+(K-N) m；
可选方式六：
小区信号质量＝f(Qbeam1，Qbeam2，…，QbeamN)*(K/N) m；
可选方式七：
小区信号质量＝f(Qbeam1，Qbeam2，…，QbeamN)*(K/N) m；
可选方式八：
小区信号质量＝f(Qbeam1，Qbeam2，…，QbeamK)*(K/N) m。
在上述可选方式中，
所述f(Qbeam1，Qbeam2，…，QbeamN)为N个波束的波束质量的线性平均；其中，其中，所述N个波束为所述小区内波束质量最优的N个波束；
所述f(Qbeam1，Qbeam2，…，QbeamK)为K个波束的波束质量的线性平均；所述K个波束的波束质量超过所述质量门限；。故在可选方式一、可选方式二、可选方式五及可选方式六中，仅有N个波束质量最佳的波束质量超过质量门限的波束的波束质量参与小区信号质量的技术，而在可选 方式三、可选方式四、可选方式七及可选方式八中，所有波束质量超过质量门限的波束的波束质量都参与小区信号质量的计算。
在上述计算函数关系中，N为数量门限；所述Qoffset1为所述第一偏移值；所述Qbeamx为第x个波束的波束质量。
在本实施例中，所述Qoffset1可为基站或移动管理实体等网络侧设备预先配置的偏移量。在本实施例中所述第一偏移量的取值为正数，所述m可为正数，所述m的取值可为小数或整数，可选为1、2或3等取值。这里的m为计算小区信号质量中补偿值得指数参量的一种。
所述步骤S123的可实现方式也包括多种，以下提供几种可选方式：
可选方式一：
小区信号质量＝f(Qbeam1，Qbeam2，…，QbeamN)+(K-N) m；
可选方式二：
小区信号质量＝f(Qbeam1，Qbeam2，…，QbeamK)+(K-N) m*Qoffset2；
可选方式三：
小区信号质量＝f(Qbeam1，Qbeam2，…，QbeamN)*(K/N) m；
可选方式四：
小区信号质量＝f(Qbeam1，Qbeam2，…，QbeamK)*(K/N) m*Qoffset2；
可选方式五：
小区信号质量＝f(Qbeam1，Qbeam2，…，QbeamN)*(K-N) m；
可选方式六：
小区信号质量＝f(Qbeam1，Qbeam2，…，QbeamN)+(K-N) m*Qoffset2；
可选方式七：
小区信号质量＝f(Qbeam1，Qbeam2，…，QbeamN)*(K/N) m；
可选方式八：
小区信号质量＝f(Qbeam1，Qbeam2，…，QbeamN)*(K/N) m*Qoffset2；；
其中，所述f(Qbeam1，Qbeam2，…，QbeamK)为K个波束的波束质量的线性平均，其中，所述K个波束为波束质量超过波束门限的波束；
所所述f(Qbeam1，Qbeam2，…，QbeamN)为N个波束质量最佳的波束的波束质量的线性平均。所述Qoffset2为所述第二偏移值，所述Qbeamx为第x个波束的波束质量；所述x为小于或等于K的整数，m的取值为正数。
在本实施例中，f(Qbeam1，Qbeam2，…，QbeamK)为波束质量超过质量门限的波束的波束质量的线性平均，即对应于前述第一质量参数；所述(K-N)*Qoffset2或所述(K/N)*Qoffset2对应于前述所述第二质量参数。
显然在本实施例中，K与小区信号质量的正相关，可体现在：K与小区信号质量的正比关系，或者，正向加权关系等。
在一些实施例中，所述Qoffset1的取值和所述Qoffset2的取值相同，总之，所述UE可能会从基站接收Qoffset1及Qoffset2这两个参数。
在还有一些实施例中，K小于N，与，K大于或等于N，这两种情况下，计算小区信号质量的偏移量为同一个，该偏移量可以称为共用偏移量，此时，所述基站可能仅会向UE下发一个Qoffset0的取值。
则不管K是小于N，还是K大于或等于N的取值，都可以采用如下公式的至少其中之一，来计算所述小区信号质量。
小区信号质量＝f(Qbeam1，Qbeam2，…，QbeamN)+(K-N) m；
小区信号质量＝f(Qbeam1，Qbeam2，…，QbeamN)+(K-N) m*Qoffset0；
小区信号质量＝f(Qbeam1，Qbeam2，…，QbeamN)*(K/N) m；
小区信号质量＝f(Qbeam1，Qbeam2，…，QbeamN)*(K/N) m*Qoffset0；
小区信号质量＝f(Qbeam1，Qbeam2，…，QbeamK)+(K-N) m；
小区信号质量＝f(Qbeam1，Qbeam2，…，QbeamK)+(K-N) m*Qoffset0；
小区信号质量＝f(Qbeam1，Qbeam2，…，QbeamK)*(K/N) m；
小区信号质量＝f(Qbeam1，Qbeam2，…，QbeamK)*(K/N) m*Qoffset0。
在一些实施例中，所述小区信号质量还可直接是f(Qbeam1，Qbeam2，…，QbeamK)
如图8所示，根据所述小区信号质量进行UE的小区选择或重选可采用以下方法：
步骤S101：根据所述小区信号质量进行小区评级；
步骤S102：判断多个小区的所述小区评级的差值是否小于差值门限；
步骤S103：若所述差值小于所述差值门限，选择波束质量超过所述质量门限的波束个数最多的小区为小区选择或重选的目标小区。
在一些情况下，若利用本实施例中方法进行小区选择或重选时，所述小区信号质量可为对应小区所包含波束的波束质量的线性平均，例如，选择出小区A中所包含的波束质量超过质量门限的波束为M个，则该小区A的小区质量，可为该M个波束的波束质量的平均。
在另一些情况下，本实施例中用于计算小区评级的小区信号质量，也可以是与超过质量门限的波束个数正相关的小区信号质量。
在本实施例中所述小区信号质量，可为RSRP或RSRQ等取值，在本实施例中，基于小区信号质量计算出小区评级。例如，当UE初始接入网络时，会扫描附近的网络，然后计算出所述小区信号质量，然后根据小区信号质量进行小区评级，然后判断UE扫描到的多个小区中小区评级的最高的几个小区的小区评级的差值是否小于差值门限，若小于差值门限，说明这几个小区的信号质量差不多，则此时UE优先选择波束质量超过质量门限的波束最大的小区，为UE初始选择的小区，完成小区选择。
在进行UE的初始小区选择时，可以采用如下公式计算所述小区评级：
R＝Qmeas；例如，所述Qmeas前述小区内波束的线性平均值，再例如，所述Qmeas还可为线性平均值与第一补偿值或第二补偿值之和。
在一些实施例中，所述R＝Qmeans可为参考信号的RSRP或RSRQ。
所述小区重选可为UE已经接入到网络，UE会在满足重选条件时进行小区重选，则此时UE已经有了当前的服务小区，一般情况下，所述UE可以扫描到服务小区及与服务小区相邻的邻小区的小区信号质量，该小区信号质量可以采用本实施例中任意一种方式计算。然后基于该小区信号质量计算小区评级，然后基于小区评级的差值与差值门限的比较，来进行小区重选。
例如，根据小区信号质量进行小区评级，然后判断UE扫描到的多个小区中小区评级的最高的几个小区的小区评级的差值是否小于差值门限，若小于差值门限，说明这几个小区的信号质量差不多，则此时UE优先选择波束质量超过质量门限的波束最大的小区，为UE完成小区重选。
进行小区重选时，在服务小区和邻小区的小区评级相近时，为了减少UE的不必要的切换，可以采用如下函数关系计算所述小区评级。
R s＝Q meas,s+Q Hyst-Qoffset temp
R n＝Q meas,n-Qoffset-Qoffset temp；
其中，所述Rs可服务小区的小区评级；所述Rn可为邻小区的小区评级；所述Q Hyst可服务小区的测量迟滞，Qmeas,n是邻小区的小区信号质量，例如，可为RSRQ或RSRP；Qmeas,s是服务小区的小区信号质量；Qoffset为邻小区的第一测量偏置，Qoffset temp为小区的临时偏置。
在一些实施例中，所述步骤S101可包括以下至少之一：
判断多个同频小区的所述小区评级的差值是否小于差值门限；
判断多个具有相同优先级的异频小区的所述小区评级的差值是否小于差值门限。同频小区为小区频点相同的小区，异频小区为小区频点不同给的小区。若多个小区既非同频小区，也非具有相同优先级的异频小区，则不是基于差值门限进行小区选择或重选的小区，从而避免不具有相同优先级的异频小区采用本实施例提供的小区重选或选择方法，导致UE选择到小 区信号质量差的小区，进而导致的UE的通信质量差的问题。
以上提供了几种计算小区信号质量的方式，但是具体实现时，不局限于上述任意一种。
在一些实施例中，如图3所示，所述方法还包括：
步骤S100：从基站接收计算参数。在本实施例中，所述计算参数还可包括：计算函数，这里的计算函数可为前述步骤S122和/或步骤S123中的计算关系式，该计算函数也可以为预先由基站和UE协商的，或已经写入通信标准中的函数关系式，即预先配置在UE中的。总之，所述计算参数，可为用于计算所述小区信号质量的各种参数。所述计算参数可包括：符号参数、例如，运算符号、因变量的变量参数，例如，波束个数、例如，偏移量，例如，波束质量等变量参数。在一些实施例中所述计算参数还可包括：差值门限。所述差值门限，用于进行小区重选的目标小区的确定；若多个小区的小区评级的差值小于所述差值门限时，选择波束质量超过所述质量门限的波束个数最多的小区为目标小区；所述小区评级是基于小区的所述小区信号质量确定的。
在一些实施例中所述计算参数可为预先存储在所述第一通信设备中的，第一通信设备本地读取所述计算参数即可。例如，所述计算参数可为规定在通信协议中的，所述第一通信设备在出厂之前就被写入了所述计算参数。在还有一些实施例中，所述计算参数可为所述第一通信设备和第二通信设备预先协商的，在本次执行所述步骤S110至步骤S120时，可以本地读取所述计算参数即可。
所述步骤S120可包括步骤S120’；所述步骤S120’可包括：根据所述波束个数，利用所述计算参数确定所述小区信号质量。
在本实施例中，所述计算参数可包括：质量门限、数量门限、偏移量及指数参量中的一个或多个。在本实施例中，所述偏移量可为前述第一偏 移量、第二偏移量及共用偏移量其中的一个或多个。所述指数参量可为前述函数中的m。
在本实施例中，所述步骤S100可包括：接收所述基站发送的携带有所述计算参数的广播消息；和/或，向所述基站发送请求消息；接收基站基于所述请求消息发送的所述计算参数。
在本实施例中所述广播消息可为系统消息。所述计算参数可以直接携带在广播消息，这样的话，只要位于该小区内的UE就能够接收到该计算参数。
所述广播消息中可以携带一个或多个系统消息块(System Information Block，SIB)，所述计算参数可为SIB中的消息内容，例如，承载在SIB中的特定字段中。
在一些实施例中，所述系统消息可为基本系统消息和辅助系统消息。所述基本系统消息会由基站周期性的广播，而所述辅助系统消息基站仅会基于UE的请求进行发送。所述计算参数还可以携带在所述辅助系统消息中，若一个UE新驻留该小区之后，所述UE可以通过随机接入请求等向基站请求所述辅助系统消息，这样就会接收到辅助系统消息中携带的发送参数。故在一些实施例中，所述UE可以通过向基站发送请求，并接收基站基于请求返回的计算参数，计算所述小区信号质量。
在一些实施例中，所述请求消息不局限于基于随机接入请求发送，在另一些实施例中，还可以基于其他发送方式所述随机请求。
所述计算参数，可为基站接收到请求之后在小区内广播的，也可以通过无线连接(Radio Resource Connection，RRC)等单播消息单播给所述UE，在还有些实施例中，还可以通过组播方式组播多个均请求所述计算参数的UE的。
在一些实施例中，所述步骤S120可包括：
当所述UE处于空闲态或去激活态时，根据波束质量超过质量门限的波束的波束质量及K，确定所述小区信号质量。
在本实施例中若所述UE处于空闲态，或者，是去激活态，才采用本申请实施例提供的方法，计算与K正相关的小区信号质量。
所述空闲态为所述UE与网络侧未建立RRC连接的状态；所述去激活态，所述UE与无线侧未建立RRC连接但是与核心网侧建立有连接的状态。
所述网络侧可包括无线侧和与所述无线侧连接的核心网侧。典型的无线侧的无线网元可包括：基站，或无线网络控制器(Radio Network Controller，RNC)。典型的核心网的网元可包括：移动管理实体(MME)或网关(Gateway，GW)等。
当然在一些实施例中，所述方法还可应用于处于连接态的UE中。所述连接态为所述UE与无线侧和核心网侧都建立有连接的状态。
如图4所示，本申请实施例提供一种小区信号质量确定方法，应用于第二通信设备，该第二通信设备可为基站等设备，包括：
步骤S210：获取计算参数，所述计算参数至少包括：质量门限及偏移量；其中，所述质量门限，用于供第一通信设备确定波束质量超过所述质量门限的波束个数；所述偏移量及所述波束个数，用于计算补偿值；所述补偿值，用于计算小区信号质量；
步骤S220：发送所述计算参数。
这里的基站可为无线侧设备，可为演进型基站(eNB)或下一代基站(gNB)等。
步骤S210中获取计算参数，可包括：读取预先配置的计算参数，也可以包括基于参考参数，动态确定所述计算参数。在本实施例中，所述计算参数可至少包括质量门限，所述质量门限可用于UE确定波束质量超过质量门限的波束，即波束质量好的好波束。例如，根据当前负载量，可动态确 定当前小区的波束质量的质量门限等。
在步骤S220中发送计算参数，具体可包括：将所述计算参数携带在广播消息中，广播发送，例如，周期性的广播携带有所述计算参数的系统消息。
在一些实施例中，所述步骤S220可包括：
接收基站发送的请求消息；
在接收到所述请求消息之后，发送所述计算参数。
在还有一些实施例中，所述步骤220可包括：
统计在预定时间段内请求所述计算参数的UE的个数；
当所述UE的个数超于预定值时，广播所述计算参数，或者向请求计算参数的多个UE组播所述计算参数；
当所述UE的个数小于预定值时，向请求所述计算参数的UE单播所述计算参数。
所述预定值可为1、2或3等具体取值。
在一些实施例中，
数量门限，其中，所述数量门限，用于计算所述小区信号质量；
指数参量，用于计算所述补偿值；
其中，所述偏移量包括：第一偏移量、第二偏移量及共用偏移量的至少其中之一，所述第一偏移量，用于当波束个数K大于或等于N时，计算所述补偿值，其中，N为所述数量门限；所述第二偏移量，用于当K小于N时，计算补偿值；所述共用偏移量，用于当K大于或等于N时和K小于N时，计算所述补偿值；所述补偿值，用于确定小区信号质量。此处的所述指数参量可为前述的m。所述计算参量还可以包括：前述函数中的其他参量，例如，计算函数中的运算符等。
在一些实施例中，所述计算参数还包括：差值门限；其中，所述差值 门限，用于进行小区重选的目标小区的确定；若多个小区的小区评级的差值小于所述差值门限时，选择波束质量超过所述质量门限的波束个数最多的小区为目标小区；所述小区评级是基于小区的所述小区信号质量确定的。
在一些实施例中，所述第一偏移量和所述第二偏移量的取值相同。
在另一些实施例中，所述偏移量不区分第一偏移量和第二偏移量，不管K是不小于N，还是小于N，都可以基于一个相同的偏移量计算所述小区信号值，该偏移量称之为共用偏移量。
本实施例还提供另一种信息处理方法，包括：
基站发送计算参数；
UE接收所述计算参数；
UE确定出待计算小区信号质量的小区的波束质量超过质量门限的波束个数；
UE以所述波束个数为因变量，利用所述计算参数计算出与所述波束个数正相关的小区信号质量；
UE根据所述小区信号质量，进行小区选择或重选。
所述小区信号质量越高，则对应的小区被重选的概率越高。
在一些实施例中，所述计算参数可至少包括：前述的第一偏移量、第二偏移量及共用偏移量的至少其中之一；其中，所述第一偏移量和第二偏移量的取值可以相等，也可以不相等。所述第一偏移量和所述第二偏移量可以统称为偏移量；所述偏移量可为所述基站中静态配置的参数，也可以是所述基站动态确定的。
所述共用偏移量，同时可以用于K小于N时的小区信号质量的计算，还可以用于K大于或等于N时的小区信号质量的计算。
例如，所述偏移量可与所述小区的小区频点正相关，例如，所述小区频点为小区可提供的载频的频率，这样确定小区信号质量不仅可以减少UE 的小区选择或重选频次，还促使优先选择高频点的小区，以确保UE的通信质量。
又例如，所述偏移量与所述小区的负载量负相关，这样确定小区信号质量不仅可以减少UE的小区选择或重选频次，还可以促使UE优先重选到负载率较低的小区，从而实现小区之间的负载均衡。
在一些实施例中，所述数量门限可以是基站预先配置的，也可以是根据小区的参数动态的确定的，例如，N可与小区提供的波束的总个数正相关。这样的不同的小区对应的N的取值不同。
如图9所示，本申请实施例还提供一种小区选择或重选方法，包括：
步骤S310：确定小区内波束质量超过质量门限的波束的波束个数；
步骤S320：根据所述波束个数，确定小区选择或重选的目标小区。
在本实施例中，可以直接根据对应小区的波束质量超过质量门限的波束个数来选择小区选择或重选的目标小区，例如，终端根据当前测得的多个小区中包括的波束质量超过质量门限的最多波束的小区为目标小区进行小区的初始选择或者重选。在一些实施例中，在进行小区选择或重选时，可以不用计算小区信号质量。但是在一些实施例中还会计算小区信号质量，再基于小区信号质量及小区内波束质量超过质量门限的小区的波束个数来选择目标小区。故所述步骤S320可包括：
基于小区信号质量进行小区评级；
判断多个小区的所述小区评级的差值是否小于差值门限；
若所述差值小于所述差值门限，选择所述波束个数最大的小区作为小区选择或重选的目标小区。
此处的小区信号质量可以采用任意一种方法进行计算，例如，可以采用图1至图4中所示的方法进行计算。
在一些实施例中，所述判断多个小区的所述小区评级的差值是否小于 差值门限，包括以下至少之一：
判断多个同频小区的所述小区评级的差值是否小于差值门限；
判断多个具有相同优先级的异频小区的所述小区评级的差值是否小于差值门限。
在本实施例中的所述差值门限可由基站通过各种消息下发的，例如，通过系统消息下发的，也可以是预先配置在基站中的。
如图10所示，本实施例还提供一种通信设备，包括：
第三确定单元310，配置为确定小区内波束质量超过质量门限的波束的波束个数；
选择单元320，配置为根据所述波束个数，确定小区选择或重选的目标小区，例如，选择所述波束个数最大的小区作为小区选择或重选的目标小区。
所述第三确定单元310及所述选择单元320均可对应于程序单元，可以通过处理器的执行实现波束质量查过质量门限的波束个数的统计及目标小区的选择。
所述选择单元320，配置为基于小区信号质量进行小区评级；判断多个小区的所述小区评级的差值是否小于差值门限；若所述差值小于所述差值门限，选择所述波束个数最大的小区作为小区选择或重选的目标小区。
所述多个小区的小区评级的差值包括：
多个小区之间的小区评级的差值，例如，小区A和小区B，所述小区评级的差值为：所述小区A的小区评级与小区B的小区评级之间的差值。
在一些实施例中，所述选择单元320，还配置为执行以下至少之一：
判断多个同频小区的所述小区评级的差值是否小于差值门限；
判断多个具有相同优先级的异频小区的所述小区评级的差值是否小于差值门限。
以下结合上述任意实施例提供几个具体示例：
示例1：
本示例提供一种小区信号质量确定方法，包括：
网络侧广播小区信号质量计算相关的参数(即计算参数)，可包括：判断是否为好波束的质量门限Threshold，和参与计算小区信号质量的最多个波束的数量门限N。
特别的，该波束质量可以是RSRP，RSRQ或SINR；
该计算参数可以是通过周期性的系统消息广播或者是按需求(on demand)的方式获取，即UE向基站请求获得；
闲置态(Idle)或去激活态(inactive)的UE应用如下公式计算服务小区和邻区的质量：
线性平均的基础上，根据实际测量到的超过门限的波束数K，进行调整得到最终的小区信号质量；如K>N，这样小区信号质量会被调高一些；K<N，此时，小区信号质量会被调低一些。
如果某小区实际测量到的超过质量门限的波束个数K>＝N，则小区信号质量＝线性平均(Qbeam1，Qbeam2，…，QbeamN)+(K-N)*Qoffset1；或，小区信号质量＝线性平均(Qbeam1，Qbeam2，…，QbeamN)*K/N*Qoffset1
其中，Qbeam1，Qbeam2，…，QbeamN为UE检测到的超过质量门限的N个最好的beam的质量，Qoffset1为对小区信号质量的偏移量；
如果某小区实际测量到的超过质量门限的beam数K<N，则
小区信号质量＝线性平均(Qbeam1，Qbeam2，…，QbeamK)+(K-N)*Qoffset2
或变形：
小区信号质量＝线性平均(Qbeam1，Qbeam2，…，QbeamK)*K/N*Qoffset2
其中，Qbeam1，Qbeam2，…，QbeamN为UE检测到的超过质量门限 的K个最好的beam的质量，Qoffset2为对小区信号质量的偏移量。
特别地，对于同一个小区选择或重选过程，Qoffset2可以与Qoffset1相同，也可以不同；对于小区选择和重选过程，对应的这两个参数可以相同、也可不同；这两个参数的发送方式可以是周期性系统广播的、也可是按需发送的(可与质量门限Threshold的和N一起或独立发送)，还可以是标准中固定好的值。UE根据计算出的服务小区和邻区质量，以及标准定义的选择或重选准则，进行小区的选择或重选过程。
示例2：
对于闲置态或去激活态的UE，小区选择或重选过程的小区信号质量计算，既要考虑最好的多个波束的线性平均之后的结果，也要考虑满足门限的好波束的数目。否则如果只看好波束的线性平均后的数值(如下表1所示)，可能会选择或重选到好波束数少的小区。而由于波束的质量变化较快，可能会导致UE频繁进行重选或产生乒乓重选效应，浪费UE的功耗。
Figure PCTCN2019070695-appb-000001
从表1可见，当N＝5/4时，小区2的小区信号质量最高；当N＝3/2/1时，小区1的信号质量最高。而实际上，由于小区1的好波束数更多，且最好的三个波束都好于小区2的三个波束，UE应该选择或重选至小区1才更合理。因此，合理的小区计算，既与测量到的好波束数有关，也与网络侧配置的N值相关。本申请提案提出了一种既考虑好波束线性平均的结果，又考虑好波束的波束数目，以及网络侧配置的N的小区信号质量计算方法，满足空闲态和去激活态下UE选择或重选的需求。
在示例1和示例2中，所述好波束即为波束质量大于质量门限的波束，即前述波束质量超过质量门限的波束。
示例3：
本示例提供一种小区选择或重选方法，包括：
基站广播小区质量计算相关的参数，例如质量门限、数量门限及差值门限等计算参数。
UE利用线性平均的公式计算邻小区和/或本小区的小区质量。
对于同频或相同优先级的异频小区，根据小区评级准则对当前的服务小区和邻小区进行评级：
R s＝Q meas,s+Q Hyst-Qoffset temp
R n＝Q meas,n-Qoffset-Qoffset temp
在本示例中，Qmeas,s为服务小区的参考信号接收功率RSRP，Q Hyst为服务小区的测量迟滞，Qmeas,n是目标小区的参考信号接收功率RSRP，Qoffset为目标小区的第一测量偏置，Qoffset temp为小区的临时偏置。对于评级差距在一定范围差值门限(Delta)内的小区，认为小区质量相当，UE优先重选到质量超过门限的波束数目最多的小区。
特别地，该Delta值可能是标准定义好的、固定在标准中的，也可能是基站通过广播或者按需的方式发给UE的。
如图5所示，本实施例提供一种通信设备，所述通信设备为第一通信 设备，所述第一通信设备可为UE，包括：
第一确定单元110，配置为确定小区内波束质量超过质量门限的波束的波束个数；
第二确定单元120，配置为根据所述波束个数，确定小区信号质量。
在一些实施例中，K与所述小区信号质量正相关。
所述第一确定单元110和第二确定单元120，均可以对应于UE中的中央处理器、微处理器、数字信号处理器、应用处理器、可编程阵列或应用处理器等。
所述处理器可通过计算机程序等可执行指令的执行，确定出与小区信号质量正相关的小区信号质量。
在一些实施例中，所述第二确定单元120，具体计算波束质量超过质量门限的至少部分波束的波束质量的线性平均；
当所述波束个数K大于或等于数量门限N时，根据所述线性平均及第一补偿值，确定所述小区信号质量，其中，所述小区信号质量不小于所述线性平均；
或者，
当K小于N时，根据所述线性平均及第二补偿值，确定所述小区信号质量，其中，所述小区信号质量小于所述线性平均。
在一些实施例中，所述第二确定单元120，可配置为采用以下函数的至少其中之一计算所述小区信号质量；
