A stable modulation-index Bluetooth (BT) transmitter circuit includes a baseband modulator circuit to generate a baseband BT signal. An intermediate frequency (IF) circuit adds a frequency offset to the baseband BT signal with a low IF and generates a modulated signal. A digital-to-analog converter (DAC) converts the modulated signal to an analog signal that is upconverted using a voltage controlled oscillator (VCO). The baseband frequency offset is subtracted from the corresponding radio-frequency (RF) signal by reducing the local oscillator (LO) frequency by the same amount. This has the effect of modulating the carrier leakage away from the center frequency of the transmitted BT signal. The resulting RF signal is transmitted to a receiver.

UE-related measurements taken on a Pcell in a wireless communication system are formed into a set of data. The Pcell overlaps with Scell(s). The UE-related measurements on the Pcell are for a specific UE in the Pcell. Using a ML algorithm applied to the set of data, achievable channel quality is predicted for the specific UE for each of the Scell(s). The predicted achievable channel qualities are output for the specific UE to be used for Scell selection. At a RAN node, the set of data is sent toward an Scell prediction module for the module to determine information suitable to enable Scell selection for the specific UE. The RAN node receives information from the module allowing the RAN node to inform the selected UE of Scell(s) to be used for Scell selection for the specific UE. A node may train the ML algorithm using UE-related measurements on the Pcell.

Aspects of the subject disclosure may include, for example, a method in which a processing system identifies a plurality of performance indicators comprising device performance indicators for a plurality of communication devices on a cellular network and network performance indicators for the cellular network. The method also includes obtaining historical data regarding the plurality of performance indicators for each of a series of time points during a past time period; the historical data for each of the plurality of performance indicators form an array of values for that performance indicator.

Other embodiments are disclosed.

Apparatus and methods that mitigate interferences between two vehicle-to everything (V2X) communications channels to maintain a sufficient communication range for both channels.
