Automatic repeat request (ARQ) schemes, and in particular hybrid-ARQ (HARQ) schemes,
which jointly adopt forward error correction (FEC) and ARQ, are essential to provide reliable …

Rate-splitting multiple access (RSMA) has attracted a lot of attention as a general and
powerful multiple access scheme. In the uplink, instead of encoding the whole message into …

Non-orthogonal multiple access (NOMA) is a promising candidate radio access technology
for future wireless communication systems, which can achieve improved connectivity and …

This paper employs hybrid automatic repeat request (HARQ) to assist the cognitive non-
orthogonal multiple access (NOMA) scheme for secure transmission in Internet of Things …

As opposed to hybrid automatic repeat request with incremental redundancy (HARQ-IR) that
all the resources are occupied to resend the redundant information, cross-packet HARQ (XP …

This work investigates the design of Hybrid Automatic Repeat Request (HARQ) strategies for
downlink Rate-Splitting Multiple Access (RSMA). The existence of private and common …

This work presents a novel K-Repetition based Hybrid Automatic Repeat reQuest (HARQ)
scheme for uplink sparse code multiple access (SCMA) systems. Our core idea is to apply …

This work presents a novel K-Repetition based HARQ scheme for LDPC coded uplink
SCMA by employing a network coding (NC) principle to encode different packets, where K …

A variable-length cross-packet hybrid automatic repeat request (VL-XP-HARQ) is proposed
to boost the spectral efficiency (SE) and the energy efficiency (EE) of communications. The …

Automatic repeat request (ARQ) schemes, and in particular hybrid-ARQ (HARQ) schemes,
