Reducing Latency in MEC Networks With Short-Packet Communications

IEEE Transactions on Vehicular Technology
Different from the conventional transmit-then-compute scheme, which has been widely considered in mobile edge computing (MEC) networks, we propose a transmit-while-compute scheme to reduce the average latency.

Performance analysis of short-packet communications with incremental relaying

Computer Communications, 2021
Abstract In the fifth generation (5G) cellular system, short-packet communication is a key enabler to support critical applications, i.e., ultra-reliable low-latency communications (URLLCs), where finite block-length codewords are adopted. However, the short-packet communication suffers from a higher decoding error rate and has a lower transmission ...

Age of Information for Short-Packet Covert Communication

IEEE Wireless Communications Letters, 2021
In this letter, we develop a new framework to jointly characterize covertness and timeliness of short-packet communications, in which a new metric named covert age of information (CAoI) is first proposed and then a closed-form expression for the average CAoI is derived.

Coding Performance Modeling for Short-Packet Communications

2019 53rd Asilomar Conference on Signals, Systems, and Computers, 2019
In this paper, an analytic model is developed to predict the performance of modern error correcting codes and modulation schemes over wireless channels with non-ideal channel estimation. The model is based on recent advances in finite- blocklength information theory, which provide accurate performance metrics for the transmission of short packets.

NOMA-Assisted Secure Short-Packet Communications in IoT

IEEE Wireless Communications, 2020
The Internet of Things (IoT) is expected to provide ubiquitous wireless machine-type communication devices and extensive information collection, resulting in an unprecedented amount of privacy and secrets exposed to the radio space. Security issues become a major restriction on the further development of IoT.
