Age and Energy Tradeoff for Multicast Networks With Short Packet Transmissions
IEEE Transactions on Communications, 2021Age of information (AoI) and energy efficiency (EE), as two important performance metrics in status update systems, usually cannot be simultaneously optimized. This paper investigates the age and energy tradeoff for multicast networks with retransmissions, where each sensed status update is encoded as a short blocklength packet and is broadcasted to ...

Permutation-Based Short-Packet Transmissions Improve Secure URLLCs in the Internet of Things [PDF]
IEEE Internet of Things Journal, 2023 As a promising candidate for ultrareliable and low-latency communications, the recent permutation-based transmission concept substantially improves the resource utilization efficiency in the Internet of Things (IoT). In this context, the Age of Information (AoI) experienced in permutation-based short-packet transmissions is characterized in a wiretap ...

A Method for Reliable Permutation Transmission in Short-Packet Communication Systems
2023The paper describes the research, development, and implementation of a method for permutation transmission over communication channels with a bit error probability close to 0.5. The developed method can be used for communication systems with non-separable factorial coding, in particular, to implement a three-pass cryptographic protocol based on ...

Downlink NOMA Transmission for Low-Latency Short-Packet Communications
2018 IEEE International Conference on Communications Workshops (ICC Workshops), 2018This work introduces non-orthogonal multiple access (NOMA) into short-packet communications to reduce latency over the air interface in wireless networks. Specifically, we address the optimization of transmission rates and power allocation to maximize the effective throughput of the user with a higher channel gain while guaranteeing the other user ...

Sparse Vector Coding-based Superimposed Transmission for Short Packet URLLC
2021 IEEE Wireless Communications and Networking Conference Workshops (WCNCW), 2021Sparse vector coding (SVC) based on position indices is emerging as a key enabler for short packet ultra-reliable and low latency communications (URLLC), since it can achieve better block error rate (BLER) performance and lower transmission latency. In this paper, we propose a SVC-based superimposed transmission (SVC-ST) scheme to further enhance the ...
