正如 Android 开发人员参考所述，TelephonyManager 仅针对 5G SA 网络返回 CellInfoNr，而针对 5G NSA 网络返回 CellInfoLte。我需要获取 NSA 网络的信号强度信息，但找不到有关如何从 CellSignalStrengthLte 获取它的信息。

据我了解，5G 使用同步信号和信道状态信息，而不是像 4G 那样使用特定于小区的参考信号，因此通常的 RSRP、RSRQ 和 RSSI 信息对 5G 网络毫无用处。

我是否理解错了，因此这些指标实际上与 NSA 网络相关，或者我如何从 CellSignalStrengthLte 对象中获取相关指标？

也许可以帮助您致电 TelephoneManager。您可以在下面看到所有类型。

使用这样的函数：

   fun getNetworkInfo() : Int {
    val networkInfo = connectivityManager.activeNetworkInfo
    if (networkInfo.type == ConnectivityManager.TYPE_MOBILE) {
    return networkInfo.subtype
    } else -1
   }

而不是解析 Int 以检查哪种类型的连接。

连接类型：

 * Do not add negative types.
