Dr. Angela Yingjun ZhangTopic: Service Caching in Mobile Edge Computing

Abstract

In recent years, researchers have investigated a wide range of topics related to mobile edge computing (MEC) from both the mobilecomputing and the wireless communications perspectives, such as MEC architecture and virtualization, computation offloading,task scheduling and resource management. In comparison, service caching has been severely under-investigated. Service cachingrefers to pre-storing the necessary programs for task computation at MEC servers. It effectively reduces the real timedelay/bandwidth cost on acquiring and initializing service applications when computation tasks are offloaded to the MEC servers.The limited caching space at edge servers calls for careful design of caching placement to determine which programs to cache overtime. This is in general a complicated problem that highly correlates with the computation offloading and resource allocationdecisions. In this talk, I am going to introduce our recent work on MEC service caching in various scenarios.

Dr. Kyle JamiesonTopic: Quantum Computation for MIMO Detection and LDPC Decoding in Wireless Networks

Abstract

User demand for increasing amounts of wireless capacity continues to outpace supply, and while 5G wireless designs begin to addressthis, even higher-performance 6G roadmap systems now remain impractical in part because their algorithms are extremelycomputationally demanding. The base station's computational capacity is thus becoming one of the key limiting factors on wirelesscapacity. I will discuss work in centralized radio access network (C-RAN) architecture designs backed by quantum computation. We haveimplemented two such designs on the D-Wave 2000Q quantum annealer, the first a Large MIMO detector, and the second an LDPCdecoder. Our experimental results evaluate these systems on real and synthetic channel traces, showing that 30 ?s of compute time onthe 2000Q can enable 48 user, 48 AP antenna BPSK MIMO detection at 20 dB SNR with a bit error rate of 10-6. For LDPC decoding, ourquantum decoder achieves a performance improvement over an FPGA based soft belief propagation LDPC decoder, by reaching a biterror rate of 10?8 and a frame error rate of 10-6 at an SNR gap of up to 3.5 dB.

Dr. Petar PopovskiTopic: Signposts for Latency and Reliability on the way Beyond 5G Wireless

Abstract

Perhaps the main innovation in 5G wireless systems has been the platform approach to connectivity: using a single system that anflexibly support connections with very diverse requirements. To achieve this, three generic services have been defined: enhancedMobile Broadband (eMBB), Ultra-Reliable Low-Latency Communication (URLLC), and massive Machine Type Communication (mMTC).URLLC is intended for mission-critical connectivity, postulated to have very stringent requirement both on latency and reliability. This talkwill provide a perspective on latency and reliability requirements beyond 5G. We will discuss the need to decouple latency and reliabilityinto two different design dimensions. Then it will address the issue of measuring and guaranteeing reliability and the necessity of usingmachine learning concepts in this respect. Another theme will be related to the spectrum usage and ways to assess its performance inthe context of heterogeneous connection requirements. Finally, the talk will address the impact of smart contracts and distributedledger on the IoT traffic, requiring revision of the definitions of latency and reliability.

Dr. Zhu HanTopic: Reconfigurable Intelligent Surface for 6G: Communication, Sensing, and Localization

AbstractTo spearhead the emergence of future intelligent communication and sensing platform, many advanced techniques have been investigated suchas small cell and massive MIMO to support ubiquitous high-speed data services. However, their performances greatly depend on the dynamic andunpredictable wireless propagation. Against this background, reconfigurable intelligent surface (RIS) stands out as a novel approach to improvethe quality of communication links and extend coverage. It is capable to actively shape the uncontrollable wireless environments into a desirableform via flexible phase shift reconfiguration without extra hardware or power costs. To better exploit the potential of such a technique, it isessential to develop distributed configuration, to design new protocols, to explore and implement suitable application scenarios, as well as toperform intelligent control and orchestration. This proposal will emphasize on RIS aided cellular communication and its applicability to a variety ofIoT use cases. We will first give a comprehensive introduction of the RIS techniques by revealing its unique features compared to traditionalantenna arrays. Second, RIS-aided

communications will be discussed targeting at network capacity

improvement and coverage extension from different aspects such as

hybrid beamforming design and structure optimization. Third, two

typical RIS-aided IoT applications will be developed, i.e., smart

sensing and enhanced localization. Challenges on protocol design,

signal processing, intelligent configuration, and implementation

issues will be addressed.
