Ultra-Reliable Low Latency Communications (URLLC)

Ultra-Reliable Low Latency Communications (URLLC) is a critical component of 5G technology, designed to support applications that require highly reliable data transmission and extremely low latency. Key aspects of URLLC include:


  1. Low Latency: Achieving latencies as low as 1 millisecond, which is crucial for applications where real-time responsiveness is essential, such as autonomous driving and remote surgery[1][3].
  2. High Reliability: Providing a reliability of up to 99.999%, ensuring that data transmission is highly dependable. This level of reliability is necessary for mission-critical applications where failures could have severe consequences, such as in industrial automation and smart grids[1][3].
  3. Efficient Data Transfer: Supporting efficient scheduling of data transfers, achieving shorter transmission times through larger subcarriers and even scheduling overlapping transmissions[3].

URLLC is used in various applications, including:

  1. Autonomous vehicles
  2. Industrial automation
  3. Healthcare, such as remote surgery
  4. Augmented/Virtual Reality
  5. Smart grids


To achieve these stringent requirements, 5G networks utilize technologies like network slicing, beamforming, and packet retransmission protocols[1][3][5]. URLLC is one of the three main service categories of 5G, alongside Enhanced Mobile Broadband (eMBB) and Massive Machine-Type Communications (mMTC), each serving different use cases and requirements within the 5G ecosystem[1][5].
