This paper focuses on the profit maximization problem in a reconfigurable intelligent
surfaces (RIS) aided computing network, where multiple heterogeneous users offload their …

Nonorthogonal multiple access (NOMA) with a grant-free access has received a lot of
attention due to its support to massive machine-type communication (mMTC) devices. The …

Grant-free random access is an effective solution to enable massive access for future
Internet of Vehicles (IoV) scenarios based on massive machine-type communication …

In recent years, there have been increased demands for aggregating sensor information
from several sensors owing to the spread of the Internet of Things (IoT). However, packet …

This paper considers an asynchronous grant-free non-orthogonal multiple access (NOMA)
systems which can be applied in massive machine-type communications (mMTCs) and …

An asynchronous transmission scenario for non-orthogonal multiple access (NOMA) user
signals with arbitrary phase offset is investigated in this paper. To improve the system …

In this paper, low-complexity algorithms based alternating direction method of multiplier
(ADMM) framework are proposed for joint channel estimation, activity detection and delay …

This paper performs a comprehensive survey on transmission schemes for the large‐scale
Internet of things (IoT) networks with nonorthogonal multiple access (NOMA). By solving the …
