Radio Frequency Reinforcement Learning (RFRL) is anticipated to be a widely
applicable technology in the next generation of wireless communication systems,
particularly 6G and next-gen military communications. Given this, our research
is focused on developing a tool to promote the development of RFRL techniques
that leverage spectrum sensing. In particular, the tool was designed to address
two cognitive radio applications, specifically dynamic spectrum access and
jamming. In order to train and test reinforcement learning (RL) algorithms for
these applications, a simulation environment is necessary to simulate the
conditions that an agent will encounter within the Radio Frequency (RF)
spectrum. In this paper, such an environment has been developed, herein
referred to as the RFRL Gym. Through the RFRL Gym, users can design their own
scenarios to model what an RL agent may encounter within the RF spectrum as
well as experiment with different spectrum sensing techniques. Additionally,
the RFRL Gym is a subclass of OpenAI gym, enabling the use of third-party ML/RL
Libraries. We plan to open-source this codebase to enable other researchers to
utilize the RFRL Gym to test their own scenarios and RL algorithms, ultimately
leading to the advancement of RL research in the wireless communications
domain. This paper describes in further detail the components of the Gym,
results from example scenarios, and plans for future additions.

Analyzing the Development of RFRL Gym for Reinforcement Learning in Wireless Communications
Radio Frequency Reinforcement Learning (RFRL) is poised to become a crucial technology in the next generation of wireless communication systems, including 6G and next-gen military communications. To support the development of RFRL techniques that leverage spectrum sensing, our research focuses on creating a tool called RFRL Gym. This tool aims to address two important cognitive radio applications: dynamic spectrum access and jamming.
One of the key requirements for training and testing reinforcement learning (RL) algorithms in these applications is the availability of a simulation environment that accurately replicates the conditions an agent would encounter within the Radio Frequency (RF) spectrum. This is where the RFRL Gym comes into play. It has been specifically designed to allow users to design their own scenarios, simulate RL agent interactions within the RF spectrum, and experiment with different spectrum sensing techniques.
An important aspect of the RFRL Gym is its compatibility with OpenAI gym, a popular framework for developing and evaluating RL algorithms. By being a subclass of OpenAI gym, the RFRL Gym offers users the flexibility to leverage third-party machine learning and RL libraries. This enhances the potential for interdisciplinary collaboration and allows researchers from various domains to contribute to the advancement of RL research in wireless communications.
The future of RFRL Gym is promising as its codebase will be made open-source, enabling other researchers to utilize it for testing their own scenarios and RL algorithms. By sharing this tool with the research community, we aim to foster collaboration and accelerate the progress of RL research in the wireless communications domain.
Multi-disciplinary Nature
