6G FR3 Channel Emulation and ISAC

6G aims to connect the physical, digital, and human worlds through emerging technology focusing on new spectrum utilization, artificial intelligence (AI) integration into networks and devices, digital twins, and new network architectures. It emphasizes the exploration of new frequency ranges and technologies for wireless communications, focusing on the FR3 7 GHz to 24 GHz upper mid-band.

6G Requirements: A Drive Towards Deterministic Channel Models

6G necessitates deterministic channel models due to evolving use cases and technologies. The application note outlines directives such as near-field communications, accurate location-based services, and integrated sensing and communication (ISAC), which demand more precise channel modeling than previous generations.

6G system simulations and product development require accurate channel modeling. Learn how the Keysight Channel Studio generates radio channel models for various wireless technologies.

• 6G FR3 RF Channel Modeling
  The application note explores the requirements and challenges of RF channel modeling for the 6G FR3 frequency range, mainly focusing on extreme MIMO and massive MIMO antennas. It discusses ongoing 3GPP initiatives to enhance channel modeling for this frequency range.
• Prototyping Integrated Sensing and Communications
  3GPP radio access technology supports location-based services for positioning, but the specifications do not have the built-in capability to detect objects unconnected to the radio access network. Integrated sensing and communication means using the same devices and possibly even the same signals (waveforms) for both communication and sensing purposes. Learn more about the integration of sensing capabilities into communication networks, including various sensing modes and use cases enabled by integrated sensing and communication systems.
• ISAC Channel Modeling
  The sensing part of integrated sensing and communication encompasses numerous use cases not supported by TR 38.901 channel models.
  Learn more about the requirements for channel modeling in integrated sensing and communication systems, addressing gaps in existing channel models, and ongoing 3GPP initiatives to develop suitable models.
• Prototyping TRP Monostatic Integrated Sensing and Communication System
  The Keysight Channel Studio and PROPSIM channel emulator for TRP monostatic ISAC testing enable prototyping ISAC monostatic and bistatic TRP / UE scenarios, from system simulations to testing with real hardware. The solution also emulates a range of factors like Doppler, multipath, channel delay, signal direction, range path loss, blocking effects, noise, and programmable interference for sensing and communication signals.
