1、需求

        客户需求，5G手机在部分场景需要显示成5G+。当带宽大于50M时，显示5G+。

2、Android对应接口

2.1、MTK 平台

04-24 09:55:15.854  1917  2026 D RILJ    : [UNSL]< UNSOL_PHYSICAL_CHANNEL_CONFIG [{mConnectionStatus=PrimaryServing,mCellBandwidthDownlinkKhz=15000,mCellBandwidthUplinkKhz=0,mNetworkType=LTE,mFrequencyRange=MID,mDownlinkChannelNumber=2147483647,mUplinkChannelNumber=2147483647,mContextIds=[-1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, 1, 2],mPhysicalCellId=487,mBand=0,mDownlinkFrequency=0,mUplinkFrequency=0}, {mConnectionStatus=SecondaryServing,mCellBandwidthDownlinkKhz=80000,mCellBandwidthUplinkKhz=0,mNetworkType=NR,mFrequencyRange=HIGH,mDownlinkChannelNumber=2147483647,mUplinkChannelNumber=2147483647,mContextIds=[-1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, 1, 2],mPhysicalCellId=19,mBand=0,mDownlinkFrequency=0,mUplinkFrequency=0}] [PHONE0]

可以通过ServiceState.java的getCellBandwidths获取对应带宽

public int[] getCellBandwidths() {
    return mCellBandwidths == null ? new int[0] : mCellBandwidths;
}

2.2、高通平台

        高通平台Log中找了一圈，也没找到对应判断带宽的接口，最后在QMI中中找到对应代码

    rildata::NrIconEnum_t convertUiMask(const dsd_sys_ui_mask_v01& ui_mask) {
    if (0 != (QMI_DSD_UI_MASK_3GPP_5G_UWB_V01 & ui_mask)) {
      Log::getInstance().d("[DSDModemEndPointModule]: convertUiMask UWB");
      return rildata::NrIconEnum_t::UWB;
    } else if (0 != (QMI_DSD_UI_MASK_3GPP_5G_BASIC_V01 & ui_mask)) {
      Log::getInstance().d("[DSDModemEndPointModule]: convertUiMask BASIC");
      return rildata::NrIconEnum_t::BASIC;
    } else {
      Log::getInstance().d("[DSDModemEndPointModule]: convertUiMask NONE");
      return rildata::NrIconEnum_t::NONE;
    }
  } 

SystemUI显示逻辑

private static MobileIconGroup getNrIconGroup(int nrIconType , int phoneId) {
        MobileIconGroup iconGroup = TelephonyIcons.UNKNOWN;
        switch (nrIconType){
            case NrIconType.TYPE_5G_BASIC:
                iconGroup = TelephonyIcons.FIVE_G_BASIC;
                break;
            case NrIconType.TYPE_5G_UWB:
                iconGroup = TelephonyIcons.FIVE_G_UWB;
                break;
        }
        return iconGroup;
    }

当QM上报UWB时表示为大带宽，显示5g+
