Title: Innovative Contributions of Inventor Mohamed Sana

Introduction

Mohamed Sana, an accomplished inventor based in Grenoble, France, has made significant strides in the field of telecommunications through his innovative patents. With a total of three patents to his name, he has been at the forefront of developing advanced methods that enhance cellular network functionality.

Latest Patents

One of his most recent inventions is a novel method for associating user equipment in a cellular network according to a transferable association policy. This method employs a multi-agent reinforcement learning (MARL) algorithm, designed specifically for use in heterogeneous networks like 5G. As user equipment enters the network, the associated agent downloads an instance of a pre-trained association meta model. The agent then constructs local and global observation vectors to encode both the state of the equipment and its environmental context, allowing for informed association decisions.

Additionally, Mohamed has developed a distance estimation method for Low Power Wide Area (LPWA) networks, alongside a position estimation method linked to it. This invention involves first and second nodes transmitting narrow band signals at multiple carrier frequencies to estimate the distance between them. The process harnesses complex values derived from the received signals to provide an estimation through a neural network that has been previously trained for this specific task.
