5G network subscription is increasing rapidly, especially in the industry sector, to support ultra-reliable low latency communication (URLLC) use cases. 5G network communication is well-known for its reliability and low latency. It is the best mobile network generation available today. 5G network communication enables fast and efficient communication in use cases requiring energy efficiency, massive device density, high reliability, and low latency. It is the 5G URLLC service that makes industrial automation, smart grid utility supply, intelligent transport systems, and remote diagnosis and surgery a reality.
Let’s learn more about URLLC use cases.
What Is URLLC?
In the 5G network, URLLC enables short transmission, efficient data transfer, and low latency. URLLC service ensures short transmissions either through larger subcarrier spacing or by overlapping the transmissions. URLLC service is significant when employing 5G communication technology in remote surgery and self-driving cars. The URLLC service makes the 5G network a trusted platform for mission-critical applications requiring low latency and reliable connectivity.
Mini-Slot Scheduling Ensures High Reliability and Low Latency
URLLC service in 5G supports use cases requiring extremely low latency in the range of 1 millisecond and reliability of the order 99.999%. The features of low latency and high reliability are achieved through mini-slot-based scheduling.
Usually, in mobile networks, shorter transmission is realized through larger subcarrier spacing. However, URLLC service achieves efficient scheduling by introducing mini-slot scheduling. In mini-slot scheduling, the scheduling unit is smaller than the regular slots and aids in enhancing the latency requirements needed in URLLC use cases.
Supporting Low Latency
URLLC use case data requires very low latency and utilizes mini-slot scheduling. The mini-slot transmission preempts the current data transmission for quick transmission of URLLC use case data requiring extremely low latency. Mini-slot transmission can overlap URLLC data transmission with data from other service areas – for example, enhanced mobile broadband.
Supporting High Latency
The 5G network adopts codes and protocols to achieve high reliability. URLLC data transmission includes repetition using pre-configured periodic grants. The pre-configured periodic grants are not in need of dynamic uplink grants. Logical channel prioritization restrictions are used when isolating the resources of a pre-configured grant for URLLC services. The Packet Data Convergence Protocol (PDCP) packet duplication and Low-Density Parity Check Codes (LDPC) are two other protocols and codes used in 5G architecture to enhance the reliability of URLLC data.
In the upcoming section, we will discuss one of the most significant URLLC use cases: healthcare.
URLLC Use Case: Healthcare
URLLC use cases are mission-critical applications that require end-to-end security, definite time bounded data delivery, and 99.999% reliability. Healthcare is one of the major URLLC use cases; let’s explore a few ways URLCC is used in the industry.
Remote Diagnosis and Surgery
Remote diagnosis and surgery is the emerging application of 5G URLLC service in the healthcare sector. Medical machines, patient sensors, and monitoring devices for disease diagnosis and surgical procedures must be secure and accessible. Data needs to be available for the right medical personnel, yet confidentiality must be maintained as well. 5G URLLC supports these applications.
Medical IoT Sensors
The use of IoT sensors is supported by 5G URLLC. These sensors track the location and performance of medical hardware such as ventilators, insulin pumps, ECG machines, etc. The inventory management of all these machines, supplies, drugs, and medical waste is also handled with the support of IoT sensors. Timely maintenance and repairs can be also ensured with tracking using IoT sensors.
Augmented Reality-Assisted Surgery
Augmented reality-assisted surgery is an important URLLC use case supported by 5G network architecture. Robotic arms and sensors can perform diagnosis and surgery. There is a dependency on augmented reality-assisted surgery to target surgical resection to enhance accuracy and minimize relapse risk.
Virtual Reality Headsets
The use of virtual reality (VR) headsets is a common URLLC use case in medical practice. VR headsets help doctors view the internal parts of the human body. Surgeons use VR headsets for surgery as well as surgical plan discussions. URLLC data transmission is extremely important while using VR headsets, as it helps overcome the latency issue between the action and response, thereby expanding the VR experience in the medical world.
