20230231685 · 2023-07-20 ·

Demodulation of 5G and 6G messages involves complex demodulation reference signals that occupy valuable resource grid area. Disclosed are numerous configurations of short-form demodulation reference types that provide sufficient modulation information to enable a receiver to determine all of the predetermined modulation levels of the modulation scheme, while consuming minimal resources. Selection of the appropriate modulation scheme and demodulation reference type generally depends on many competing factors. Therefore, an AI model may be required. The AI model may be trained on network data to recommend when a different modulation scheme would be beneficial, as the network default or to serve a particular user device. The AI model may be configured to select between the disclosed short-form demodulation references and prior-art demodulation reference signals, thereby optimizing the subsequent network performance as well as individual user satisfaction, while minimizing costs, bandwidth, power, and especially avoiding interference with neighboring cells.

Dynamic low-power scheme for wireless transceivers

Technologies directed to improving power for wireless transceivers are described.

PHASOR IQ DEMODULATION

A method for demodulating an RF signal to polar in-phase and quadrature (IQ) components that includes converting an RF signal with an analog-to-digital converter and calculating the polar in-phase and quadrature (IQ) components of the RF signal as an IQ phasor phase angle and an IQ amplitude using a digital processor. The analog-to-digital converter uses a sampling rate, where, when the sampling rate used has sampling rates other than 3 times an RF carrier frequency of the RF signal, a digital logic circuit splines data to the sampling rate of 3 times the RF carrier frequency of the RF signal. The digital processor calculates the polar in-phase and quadrature (IQ) components of the RF signal as an IQ phasor phase angle and an IQ amplitude using addition, subtraction, multiplication, division, and absolute value.
