  • A researcher from Nahdlatul Ulama University (UNU) Yogyakarta has proposed a method to optimize 6G network performance for efficiency and energy savings.
  • The proposed Frequency-Time Index Modulation Multiple Access (FT-IMMA) technology allows billions of devices to transmit data simultaneously without network congestion.
  • This research, published in IEEE Transactions on Vehicular Technology, aims to address challenges in 6G implementation, such as high infrastructure costs and signal obstruction.

A researcher from Nahdlatul Ulama University (UNU) Yogyakarta, I Nyoman Apraz Ramatryana, has developed a method to optimize the performance of future 6G networks, making them more efficient and energy-friendly. Apraz, who is also pursuing postdoctoral studies at Khalifa University in the UAE, introduced the Frequency-Time Index Modulation Multiple Access (FT-IMMA) technology.

With this optimization method, the results allow billions of devices to transmit data simultaneously without having to trigger network congestion.

This innovative approach allows billions of devices to transmit data simultaneously without causing network congestion. Apraz explained that 6G technology, slated for official launch in 2030, promises speeds up to 100 times faster than 5G, supporting integrations like Artificial Intelligence and the Internet of Things. However, its implementation faces significant hurdles, including high infrastructure costs, the short range of high-frequency waves, and signal blockage by physical structures.

In simple terms, this research proposes a new method so that many devices can send data simultaneously on the 6G communication network without having to queue or ask for a schedule first from the transmitter tower.

— I Nyoman Apraz RamatryanaExplaining the core function of the FT-IMMA system.

Apraz likens the data traffic in 6G networks to vehicles on a highway. Previously, vehicles could only be managed by separate controls for lanes (frequency) or entry times (scheduling). His FT-IMMA system, however, combines these into a two-dimensional approach. This allows data to "slip in" intelligently by selecting specific combinations of frequency and time resources. This novel combination is key to conserving spectrum waves and minimizing energy waste during transmission, thereby reducing the risk of data collisions compared to conventional methods.

Like a toll road, previously vehicles (data) could only be regulated by entering based on lanes (frequency) or times (entry hours) separately.

— I Nyoman Apraz RamatryanaUsing an analogy to explain the previous limitations in network traffic management.

The research, published in the IEEE Transactions on Vehicular Technology, focuses on simplifying data transmission procedures in transmitter systems. Apraz stated that the FT-IMMA scheme is projected to significantly impact six strategic areas, including immersive communication. This method offers a more efficient way to manage data flow, addressing critical challenges that could hinder the widespread adoption of 6G technology.

So that data can slip in intelligently by choosing a specific combination of frequency and time resources.
