6G Downlink Transmission via Rate Splitting Space Division Multiple Access Based on Grouped Code Index Modulation
Wenchao Zhai, Yishan Wu, Jun Zhao +1
A novel rate splitting space division multiple access (SDMA) scheme based on grouped code index modulation (GrCIM) is proposed for the sixth generation (6G) downlink transmission.…
A GCICA Grant-Free Random Access Scheme for M2M Communications in Crowded Massive MIMO Systems
Huimei Han, Lushun Fang, Weidang Lu +3
A high success rate of grant-free random access scheme is proposed to support massive access for machine-to-machine communications in massive multipleinput multiple-output systems.…
Intelligent Reflecting Surface Aided Network: Power Control for Physical-Layer Broadcasting
Huimei Han, Jun Zhao, Dusit Niyato +2
As a recently proposed idea for future wireless systems, intelligent reflecting surface (IRS) can assist communications between entities which do not have high-quality direct chann…
Sparse Message Passing Based Preamble Estimation for Crowded M2M Communications
Zhaoji Zhang, Ying Li, Lei Liu +1
Due to the massive number of devices in the M2M communication era, new challenges have been brought to the existing random-access (RA) mechanism, such as severe preamble collisions…
A High Throughput Pilot Allocation for M2M Communication in Crowded Massive MIMO Systems
Huimei Han, Xudong Guo, Ying Li
A new scheme to resolve the intra-cell pilot collision for M2M communication in crowded massive multiple-input multiple-output (MIMO) systems is proposed. The proposed scheme permi…
