技术领域
本公开实施例涉及通信技术领域，尤其涉及一种功率确定方法及终端设备。
背景技术
在移动通信系统中，为了保证业务传输(例如语音业务传输或数据业务传输)质量，终端设备可以基于S准测(即驻留小区的选择接收电平值Srxlev>0)，选择驻留小区驻留。
目前，一个小区的选择接收电平值可以通过测量该小区的参考信号接收功率(Reference Signal Received Power，RSRP)及其他参数确定，且一个小区的RSRP通常是通过对终端设备中接收到该小区的参考信号的所有逻辑天线端口的接收功率进行线性平均得到的。
然而，上述方式中，由于一个小区的RSRP是通过对多个逻辑天线端口的接收功率进行线性平均得到的，因此可能使得确定的该小区的RSRP和该小区的实际RSRP相差较大，从而可能导致终端设备将满足S准则的小区确定为不满足S准则的小区，进而终端设备重新进行小区测量和选择。如此，导致终端设备无法准确地选择驻留小区。
发明内容
本公开实施例提供一种功率确定方法，以解决终端设备无法准确地选择驻留小区的问题。为了解决上述技术问题，本申请是这样实现的：
第一方面，本公开实施例提供了一种功率确定方法，该方法应用于终端设备，该方法包括：获取M个目标比值；并根据该M个目标比值，确定目标接收功率值。其中，该目标接收功率值为目标接收天线的接收功率值，每个目标比值为M个目标功率值中的一个目标功率值与最大目标功率值的比值，该最大目标功率值为M个目标功率值中的最大值，该M个目标功率值为M个逻辑天线端口的接收功率值，该M个逻辑天线端口为终端设备的目标接收天线的逻辑天线端口，M为大于1的整数。
第二方面，本公开实施例提供了一种终端设备，该终端设备可以包括获取模块和确定模块。其中，获取模块，用于获取M个目标比值，每个目标比值为M个目标功率值中的一个目标功率值与最大目标功率值的比值，该最大目标功率值为M个目标功率值中的最大值，该M个目标功率值为M个逻辑天线端口的接收功率值，该M个逻辑天线端口为终端设备的目标接收天线的逻辑天线端口，M为大于1的整数；确定模块，用于根据获取模块获取的M个目标比值，确定目标接收功率值，该目标接收功率 值为目标接收天线的接收功率值。
第三方面，本公开实施例提供一种终端设备，该终端设备包括处理器、存储器及存储在存储器上并可在处理器上运行的计算机程序，该计算机程序被处理器执行时实现如上述第一方面中的功率确定方法的步骤。
第四方面，本公开实施例提供一种计算机可读存储介质，该计算机可读存储介质上存储计算机程序，该计算机程序被处理器执行时实现如上述第一方面中的功率确定方法的步骤。
在本公开实施例中，可以获取M个目标比值(每个目标比值为M个目标功率值中的一个目标功率值与最大目标功率值的比值，该最大目标功率值为M个目标功率值中的最大值，该M个目标功率值为M个逻辑天线端口的接收功率值，该M个逻辑天线端口为终端设备的目标接收天线的逻辑天线端口)；并根据该M个目标比值，确定目标接收功率值(该目标接收功率值为目标接收天线的接收功率值)。通过该方案，由于M个目标比值中的每个目标比值为一个目标功率值与最大目标功率值的比值，即每个目标比值可以表示每个目标功率值与最大目标功率值之间的接近程度，因此根据该M个目标比值可以确定信号发送方(例如网络设备)的各个逻辑天线端口的状态。如此，由于本公开实施例在确定终端设备的目标接收天线的接收功率值时考虑了发送方的各个逻辑天线端口的状态，因此可以使得确定的目标接收天线的接收功率值(即上述目标接收功率值)更加接近目标接收天线的实际接收功率值，即该目标接收功率值能够准确地反映终端设备所测量的小区的信号覆盖强度，从而使得终端设备可以准确地判断该小区是否满足驻留条件，进而保证终端设备可以准确地选择驻留小区。

具体实施方式
下面将结合本公开实施例中的附图，对本公开实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本公开一部分实施例，而不是全部的实施例。基于本公开中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。

本文中的术语“第一”和“第二”等是用于区别不同的对象，而不是用于描述对象的特定顺序。例如，第一预设公式和第二预设公式等是用于区别不同的预设公式，而不是用 于描述预设公式的特定顺序。
在本公开实施例中，“示例性的”或者“例如”等词用于表示作例子、例证或说明。本公开实施例中被描述为“示例性的”或者“例如”的任何实施例或设计方案不应被解释为比其它实施例或设计方案更可选或更具优势。确切而言，使用“示例性的”或者“例如”等词旨在以具体方式呈现相关概念。
在本公开实施例的描述中，除非另有说明，“多个”的含义是指两个或者两个以上，例如，多个元件是指两个或者两个以上的元件等。
本公开实施例提供一种功率确定方法及终端设备，可以获取M个目标比值(每个目标比值为M个目标功率值中的一个目标功率值与最大目标功率值的比值，该最大目标功率值为M个目标功率值中的最大值，该M个目标功率值为M个逻辑天线端口的接收功率值，该M个逻辑天线端口为终端设备的目标接收天线的逻辑天线端口)；并根据该M个目标比值，确定目标接收功率值(该目标接收功率值为目标接收天线的接收功率值)。通过该方案，由于M个目标比值中的每个目标比值为一个目标功率值与最大目标功率值的比值，即每个目标比值可以表示每个目标功率值与最大目标功率值之间的接近程度，因此根据该M个目标比值可以确定信号发送方(例如网络设备)的各个逻辑天线端口的状态。如此，由于本公开实施例在确定终端设备的目标接收天线的接收功率值时考虑了发送方的各个逻辑天线端口的状态，因此可以使得确定的目标接收天线的接收功率值(即上述目标接收功率值)更加接近目标接收天线的实际接收功率值，即该目标接收功率值能够准确地反映终端设备所测量的小区的信号覆盖强度，从而使得终端设备可以准确地判断该小区是否满足驻留条件，进而保证终端设备可以准确地选择驻留小区。
本公开实施例中的终端设备可以为移动终端，也可以为非移动终端。示例性的，移动终端可以为手机、平板电脑、笔记本电脑、掌上电脑、车载终端、可穿戴设备、超级移动个人计算机(ultra-mobile personal computer，UMPC)、上网本或者个人数字助理(personal digital assistant，PDA)等，非移动终端可以为个人计算机(personal computer，PC)、电视机(television，TV)、柜员机或者自助机等，本公开实施例不作具体限定。
本公开实施例提供的功率确定方法的执行主体可以为上述的终端设备，也可以为该终端设备中能够实现该功率确定方法的功能模块和/或功能实体，具体的可以根据实际使用需求确定，本公开实施例不作限定。下面以终端设备为例，对本公开实施例提供的功率确定方法进行示例性的说明。
本公开实施例中，在终端设备开机、从连接态转到空闲态或者重新进入服务区的情况下，终端设备需要选择某个小区驻留。在终端设备选择驻留小区的过程中，终端设备需要先获取小区的接收功率值(即终端设备在该小区中的接收功率值)，并基于S准则，通过该接收功率值判断该小区是否满足驻留条件，从而再确定是否驻留到该小区。具体的，终端设备可以获取终端设备的不同接收天线的接收功率值，并将这些接收功率值中的最大接收功率值确定为该小区的接收功率值，然后终端设备可以基于S准则，通过该小区的接收功率值判断该小区是否满足驻留条件。在该小区满足驻留条件的情况下，终端设备可以选择该小区驻留，在该小区不满足驻留条件的情况下，终端设备可以重新搜索其他小区驻留。由于M个目标比值中的每个目标比值为一个目标功率值与最大目标功率值的比值，即每个目标比值可以表示每个目标功率值与最大目标功率值之间的接近程度，因此根据该M个目 标比值可以确定信号发送方(例如网络设备)的各个逻辑天线端口的状态。如此，由于本公开实施例在确定终端设备的目标接收天线的接收功率值时考虑了发送方的各个逻辑天线端口的状态，因此可以使得确定的目标接收天线的接收功率值(即上述目标接收功率值)更加接近目标接收天线的实际接收功率值，即该目标接收功率值能够准确地反映终端设备所测量的小区的信号覆盖强度，从而使得终端设备可以准确地判断该小区是否满足驻留条件，进而保证终端设备可以准确地选择驻留小区。
下面结合各个附图对本公开实施例提供的功率确定方法进行示例性的说明。
如图1所示，本公开实施例提供一种功率确定方法，该方法可以包括下述的S201-S202。
S201、终端设备获取M个目标比值。
其中，每个目标比值可以为M个目标功率值中的一个目标功率值与最大目标功率值的比值，该最大目标功率值可以为M个目标功率值中的最大值，该M个目标功率值可以为M个逻辑天线端口的接收功率值，即每个目标功率值为一个逻辑天线端口的接收功率值，该M个逻辑天线端口可以为终端设备的目标接收天线的逻辑天线端口，M为大于1的整数。
本公开实施例中，终端设备可以有多个接收天线(即物理天线)，每个接收天线可以包括多个逻辑天线端口，不同的逻辑天线端口可以传输不同的信号。
可选地，本公开实施例中，上述目标接收天线可以为多个接收天线中的任意一个接收天线。
可选地，本公开实施例中，上述一个逻辑天线端口的接收功率值可以为该逻辑天线端口接收到的信号的功率值。其中，该信号可以为终端设备所测量的小区的参考信号。
示例性的，假设终端设备的目标接收天线包括5个逻辑天线端口(即M＝5)，且该5个逻辑天线端口的接收功率值分别记为P(1),P(2),P(3),P(4),P(5)，以及P(1)为这5个逻辑天线端口的接收功率值中的最大值，那么终端设备可以根据这5个逻辑天线端口的接收功率值获取5个目标比值，分别记为P ratio(1)，P ratio(2)，P ratio(3)，P ratio(4)，P ratio(5)，其中，
Figure PCTCN2020098247-appb-000001
S202、终端设备根据M个目标比值，确定目标接收功率值。
其中，上述目标接收功率值即为目标接收天线的接收功率值。
可选地，本公开实施例中，上述目标接收功率值，即目标接收天线的接收功率值可以为RSRP值，也可以为接收信号强度指示(received signal strength indication，RSSI)值等任意可能的接收功率值，具体可以根据实际使用需求确定，本公开实施例不作限定。
可选地，本公开实施例中，在终端设备获取M个目标比值之后，终端设备可以依次判断M个目标比值与预设阈值的大小，在M个目标比值中的全部目标比值均小于某个阈值的情况下，终端设备可以采用下述的第一预设公式，确定目标接收功率值；在M个目标比值中的任意一个目标比值大于或等于某个阈值的情况下，终端设备可以采用下述的第二预 设公式，确定目标接收功率值。
示例性的，本公开实施例中，结合上述图1，如图2所示，上述S202具体可以通过下述的S202a-S202b实现。
S202a、在M个目标比值中的全部目标比值均小于预设阈值的情况下，终端设备采用第一预设公式，确定目标接收功率值。
需要说明的是，本公开实施例中，由于M个目标比值中的每个目标比值为一个目标功率值与最大目标功率值的比值，即每个目标比值可以表示每个目标功率值与最大目标功率值之间的接近程度，因此根据该M个目标比值可以确定信号发送方(例如网络设备)的各个逻辑天线端口的状态。进而，在M个目标比值中的全部目标比值均小于预设阈值的情况下，可以理解为每个目标功率值与最大目标功率值比较接近，则终端设备可以确定发送方当前所有逻辑天线端口处于非关闭(非mute)状态，即发送方当前所有逻辑天线端口都可以正常传输信号。或者在M个目标比值中的至少一个目标比值小于或等于预设阈值的情况下，可以理解为M个比较比值中至少有一个目标比值与最大目标功率值相差较大，则终端设备可以确定发送方的所有逻辑天线端口中至少一个逻辑天线端口处于关闭(mute)状态，即发送方的所有逻辑天线端口中至少一个逻辑天线端口无法正常传输信号。
可选地，本公开实施例中，上述预设阈值具体可以根据实际使用需求确定，本公开实施例不作限定。
可选地，本公开实施例中，上述第一预设公式可以为：

其中，P为目标接收功率值，P(i)为M个目标功率值中的第i个目标功率值，M为目标接收天线上的逻辑天线端口的数量，1≤i≤M。
示例性的，以上述S201中举例的数据为例，假设5个目标比值分别记为P ratio(1)，P ratio(2)，P ratio(3)，P ratio(4)，P ratio(5)；在P ratio(1)，P ratio(2)，P ratio(3)，P ratio(4)，P ratio(5)均小于预设阈值的情况下，则终端设备可以根据上述第一预设公式，计算得到上述目标接收天线的目标接收功率值为
Figure PCTCN2020098247-appb-000003
其中
Figure PCTCN2020098247-appb-000004
S202b、在M个目标比值中的至少一个目标比值大于或等于预设阈值的情况下，终端设备采用第二预设公式，确定目标接收功率值。
可选地，本公开实施例中，上述第二预设公式可以为：
Figure PCTCN2020098247-appb-000005
其中，P为目标接收功率值，P ratio(i)为M个目标比值中的第i个目标比值，F i(P ratio(1),...,P ratio(i),...P ratio(M))为转换函数，P(i)为M个目标功率值中的第i个目标功率值，M为目标接收天线接收到的信号的数量，1≤i≤M。
本公开实施例中，上述F i(P ratio(1),...,P ratio(i),...P ratio(M))为转换函数，其可以用于将M个目标比值P ratio(1),...,P ratio(i),...P ratio(M)转换为M个加权系数。例如，同时输入M个目标比值P ratio(1),...,P ratio(i),...P ratio(M)，可以同时输出M个加权系数。其中，每个加权系数均为0至1之间的小数。
示例性的，以上述S201中举例的数据为例，假设5个目标比值分别记为P ratio(1)，P ratio(2)，P ratio(3)，P ratio(4)，P ratio(5)，那么，若P ratio(1),P ratio(2),P ratio(3),P ratio(4),P ratio(5)中至少一个大于或等于预设阈值，则终端设备可以根据上述第二预设公式，计算得到上述目标接收功率值
Figure PCTCN2020098247-appb-000006
其中，F 1,F 2,F 3,F 4,F 5可以通过将P ratio(1),P ratio(2),P ratio(3),P ratio(4),P ratio(5)同时输入到上述转换函数中得到，且F 1,F 2,F 3,F 4,F 5均为0至1之间的小数。
本公开实施例中，由于M个目标比值中的每个目标比值为一个目标功率值与最大目标功率值的比值，即每个目标比值可以表示每个目标功率值与最大目标功率值之间的接近程度，因此根据该M个目标比值可以确定信号发送方(例如网络设备)的各个逻辑天线端口的状态。如此，由于本公开实施例在确定终端设备的目标接收天线的接收功率值时考虑了发送方的各个逻辑天线端口的状态，因此可以使得确定的目标接收天线的接收功率值(即上述目标接收功率值)更加接近目标接收天线的实际接收功率值，即该目标接收功率值能够准确地反映终端设备所测量的小区的信号覆盖强度，从而使得终端设备可以准确地判断该小区是否满足驻留条件，进而保证终端设备可以准确地选择驻留小区。
可选地，本公开实施例中，终端设备在获取M个目标比值之前，可以先获取M个目标功率值，然后根据M个目标功率值，得到M个目标比值。

S201a、终端设备计算M个目标功率值中的每个目标功率值与最大目标功率值的比值，得到M个目标比值。
本公开实施例中，在终端设备获取到M个目标功率值之后，终端设备可以确定M个目标功率值中的最大值，然后终端设备可以根据M个目标功率值和M个目标功率值中的最大值确定M个目标比值，即分别计算M个目标功率值中的每个目标功率值和M个目标功率值中的最大值的比值，得到M个目标比值。可以理解，一个目标功率值可以对应一个目标比值。
本公开实施例中，对上述目标比值的其他描述具体可以参照上述S201中对目标比值 的相关描述，为避免重复，此处不再赘述。
本公开实施例中，由于M个目标比值中的每个目标比值为一个目标功率值与最大目标功率值的比值，即每个目标比值可以表示每个目标功率值与最大目标功率值之间的接近程度，因此根据该M个目标比值可以确定信号发送方(例如网络设备)的各个逻辑天线端口的状态，从而根据该目标比值确定的目标功率值准确度较高。
可选地，本公开实施例中，上述S203具体可以通过下述的S203a-S203b实现。
S203a、终端设备获取M个功率平均值。
其中，M个功率平均值中的每个功率平均值可以为M个逻辑天线端口中的一个逻辑天线端口在目标范围内的接收功率平均值。具体的，一个逻辑天线端口在目标范围内的接收功率平均值可以理解为该逻辑天线端口在目标范围内的接收到的信号的功率平均值。
可选地，本公开实施例中，上述目标范围可以为目标时长或目标带宽。具体的，M个功率平均值中的每个功率平均值可以为一个逻辑天线端口在目标时长内接收到的信号的功率平均值；或者，M个功率平均值中的每个功率平均值可以为一个逻辑天线端口在目标带宽内接收到的信号的功率平均值。具体可以根据实际使用需求确定，本公开实施例不作限定。
可选地，本公开实施例中，上述目标时长可以为满足实际使用需求的任意时长，具体可以根据实际使用需求确定，本公开实施例不作限定。
可选地，本公开实施例中，上述目标带宽可以为系统带宽，也可以为系统带宽中满足实际使用需求的任意带宽，具体可以根据实际使用需求确定，本公开实施例不作限定。
示例性的，假设终端设备的目标接收天线包括5个逻辑天线端口，目标时长为0.01h(小时)，且目标接收天线的5个逻辑天线端口在0.01h内接收到的信号的功率分别记为：P total(1),P total(2),P total(3),P total(4),P total(5)，则终端设备可以获取5个功率平均值，分别为P mean(1),P mean(2),P mean(3),P mean(4),P mean(5)，其中，

S203b、终端设备将M个功率平均值作为M个目标功率值。
本公开实施例中，在终端设备获取到M个功率平均值之后，终端设备可以将M个功率平均值作为M个目标功率值。
示例性的，以上述S203a和上述S201中的数据为例，在终端设备获取到5个功率平均值P mean(1),P mean(2),P mean(3),P mean(4),P mean(5)之后，终端设备可以将P mean(1)作为P(1)，将P mean(2)作为P(2)，将P mean(3)作为P(3)，将P mean(4)作为P(4)，将P mean(5)作为P(5)，即
Figure PCTCN2020098247-appb-000009
Figure PCTCN2020098247-appb-000010
本公开实施例中，由于每个目标功率值分别是终端设备目标接收天线的一个逻辑天线端口在目标时长或目标带宽内的功率平均值，因此终端设备获取的目标功率值能够准确的表示该逻辑天线端口接收到的功率大小，从而使得终端设备通过该目标功率值确定的目标比值的准确度较高。
可选地，本公开实施例中，在终端设备包括多个接收天线(例如N个接收天线)的情况下，终端设备确定N个接收天线中的每个接收天线的接收功率值，从而可以得到多个接收功率值。并且，在终端设备确定多个接收功率值之后，终端设备可以根据多个接收功率值中的最大接收功率值，基于S准则判断目标小区是否满足驻留条件。
示例性的，本公开实施例中，结合上述图1，如图4所示，在上述S202之后，本公开实施例提供的功率确定方法还可以包括下述的S204。
S204、在终端设备确定多个接收功率值之后，终端设备根据多个接收功率值中的最大接收功率值，基于S准则判断目标小区是否满足驻留条件。
其中，上述目标小区为终端设备所测量的小区，上述多个接收功率值为多个接收天线的接收功率值。即多个接收功率值中的每个接收功率值为多个接收天线中的一个接收天线的接收功率值。
本公开实施例中，在终端设备的目标接收天线为多个接收天线时，终端设备可以针对终端设备的每个接收天线分别执行本公开实施例中提供的功率确定方法，确定多个接收天线中每个接收天线的接收功率值，从而可以得到多个接收功率值。并且，在终端设备确定多个接收功率值之后，终端设备可以根据多个接收功率值中的最大接收功率值，基于S准则判断目标小区是否满足驻留条件。在终端设备判断目标小区满足驻留条件的情况下，终端设备可以在该目标小区发起驻网请求，在终端设备判断目标小区不满足驻留条件的情况下，终端设备可以再次搜索其他小区驻留。
本公开实施例中，由于终端设备是根据多个接收天线中的最大接收功率值，基于S准则能够来判断目标小区是否满足驻留条件的，从而该判断结果比较准确。
需要说明的是，本公开实施例中，上述各个方法附图所示的功率确定方法均是以结合本公开实施例中的一个附图为例示例性的说明的。具体实现时，上述各个方法附图所示的功率确定方法还可以结合上述实施例中示意的其它可以结合的任意附图实现，此处不再赘述。
