User Detection Performance Analysis for Grant-Free Uplink Transmission in Large-Scale Antenna Systems
Jonghyun Kim, Kyung Lin Ryu, Kwang Soon Kim
In this paper, user detection performance of a grant-free uplink transmission in a large scale antenna system is analyzed, in which a general grant-free multiple access is consider…
Ultrareliable and Low-Latency Communication Techniques for Tactile Internet Services
Kwang Soon Kim, Dong Ku Kim, Chan-Byoung Chae +9
This paper presents novel ultrareliable and low-latency communication (URLLC) techniques for URLLC services, such as Tactile Internet services. Among typical use-cases of URLLC ser…
Large-Scale Cloud Radio Access Networks with Practical Constraints: Asymptotic Analysis and Its Implications
Kyung Jun Choi, Kwang Soon Kim
Large-scale cloud radio access network (LS-CRAN) is a highly promising next-generation cellular network architecture whereby lots of base stations (BSs) equipped with a massive ant…
Latency-Optimal Uplink Scheduling Policy in Training-based Large-Scale Antenna Systems
Kyung Jun Choi, Kwang Soon Kim
In this paper, an uplink scheduling policy problem to minimize the network latency, defined as the air-time to serve all of users with a quality-of-service (QoS), under an energy c…
Cooperative Hybrid ARQ Protocols: Unified Frameworks for Protocol Analysis
Ilmu Byun, Kwang Soon Kim
Cooperative hybrid-ARQ (HARQ) protocols, which can exploit the spatial and temporal diversities, have been widely studied. The efficiency of cooperative HARQ protocols is higher th…
Generalized Cross-correlation Properties of Chu Sequences
Jae Won Kang, Younghoon Whang, Hyo Yol Park +1
In this paper, we analyze the cross-correlation properties for Chu sequences, which provide information on the distribution of the maximum magnitudes of the cross-correlation funct…
