5G is expected to be ubiquitous and to be used for many tasks that are difficult or impossible to do wirelessly today. The key will be 5G Ultra-Reliable Low-Latency Communication (URLLC), according to a new publication from 5G Americas that lays out the potential of URLLC, the ways in which those goals can be reached and the challenges that must be overcome to do so.
5G Ultra-Reliable Low-Latency Communications
URLLC applications and services provide low latency, high reliability, massive density and improved energy efficiency, according to the group. Examples of uses of URLLC are factory automation, autonomous driving, industrial internet and smart grid.
The publication, “New Services & Applications With 5G Ultra-Reliable Low Latency Communication,” describes the underpinnings of the new technology, the new approaches needed to make it a reality and describes its key requirements.
“With the wide range of unique 5G services, the context of communication will expand to vehicles, high-speed trains, drones and industrial robots with the change agent being URLLC. With such advancement, mission-critical applications have stringent communication performance and reliability requirements,” 5G Americas President Chris Pearson said in a press release. “To support such complex communication, low latency is seen as a crucial ingredient with URLLC as a key enabler in this new age of connectivity.”
The publication describes use cases for URLLC in smart transportation, industry automation and tele-surgery. It discusses the latency and reliability requirements for each and the bottlenecks that may threaten success. The document discusses performance evaluation of designs and implementation of the 5G physical layer, multiple access layers and air interface blocks that are key to latency reduction and reliability gains. Other approaches, such as multi-access edge computing, also are discussed.
The document was written by 5G Americas staff and is available for free download from the website. Rao Yallapragada from Intel and Jing Jiang from Qualcomm led the working group that wrote the paper.
