eXtended Reality XR Over 5G NR: Capacity Analysis

Abstract: 5G connectivity is supposed to bring significant elements to augmented reality, virtual reality, and mixed reality, collectively known as XR, or eXtended Reality. While 5G new radio has some support for XR through the support of ultra reliable low latency communications; the requirements for XR are more stringent. More precisely, the throughputs are on the order of 30-250 Mbps, 10-15 msec latencies for air interface and high reliability (PER 10^-2).

We will talk about challenges in terms of meeting these requirements along with some research results that may increase the capacity of the system. In particular we compare the baseline zeroforcing precoding to a precoding based on uplink sounding and interference probing and show an increase in system capacity and reliabilities.

Speaker bio: Diana Maamari received her BS and MS degrees with high distinction in electrical and computer engineering from Balamand University in Lebanon. She received her PhD in electrical and computer engineering from University of Illinois Chicago in 2015. Her research interests focus on information theory and wireless communication. She has been a senior research and standards engineer with Futurewei (Huawei USA) since May, 2015. Her current focus is researching 5G NR, in particular MAssive MIMO, extended Reality (XR), FDD enhancements and sounding reference signal design, URLLC enhancements. She has more than 20 patents and patent applications, and numerous publications in the areas of wireless communications and information theory.
