The document "Open Source-based 5G Sidelink Testbed" provides information on the configuration and implementation of a 5G sidelink testbed. It discusses the use of open-source software and hardware for creating a 5G sidelink system. The testbed includes the use of a physical sidelink feedback/control channel, resource pool allocation, and RF parameter configurations. The document also describes the OTA (over-the-air) testing using USRP (Universal Software Radio Peripheral) devices and provides results on the performance of the system. Overall, the document focuses on the technical aspects of building and testing a 5G sidelink system. The text excerpt provides details about the physical layer overview and development of the 5G Sidelink (SL) mode 2 prototype. It discusses various components such as the Physical Sidelink Shared Channel (PSSCH), Physical Sidelink Broadcast Channel (PSBCH), and SL synchronization block (S-SSB). The development process follows a software development cycle and utilizes existing 5G Open Air Interface (OAI) code. The prototype is tested using simulators and over-the-air (OTA) testing with Universal Software Radio Peripherals (USRPs). The focus is on implementing and validating the full 5G SL features. We have developed a full 5G Sidelink (SL) testbed based on open source software. The testbed includes the implementation of the Physical Sidelink Broadcast Channel (PSBCH) and the Physical SL Shared Channel (PSSCH). We have also conducted OTA testing and demonstrated synchronization between a SyncRef UE and a nearby UE. The testbed utilizes software-defined radios (SDRs) and can operate in various spectrum configurations. Our work focuses on the development of the physical layer SL channels and demonstrates the potential performance of 5G SL. We have validated our development framework through RF simulations and OTA testing, which showed promising results. The testbed has the capability to support a broad range of devices and applications, including vehicle platooning, wearable devices, industrial IoT, and public safety communication. Our goal is to provide a comprehensive set of advantages to the overall 5G network.
