Joint Transmit Precoding and Reflect Beamforming Design for IRS-Assisted MIMO Cognitive Radio Systems
Weiheng Jiang, Yu Zhang, Jun Zhao +2
Cognitive radio (CR) is an effective solution to improve the spectral efficiency (SE) of wireless communications by allowing the secondary users (SUs) to share spectrum with primar…
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.…
A Stackelberg Game Approach to Resource Allocation for IRS-aided Communications
Yulan Gao, Chao Yong, Zehui Xiong +3
It is known that the capacity of the intelligent reflecting surface (IRS) aided cellular network can be effectively improved by reflecting the incident signals from the transmitter…
Intelligent Reflecting Surface-Assisted Bistatic Backscatter Networks: Joint Beamforming and Reflection Design
Xiaolun Jia, Xiangyun Zhou, Dusit Niyato +1
Bistatic backscatter communication (BackCom) allows passive tags to transmit over extended ranges, but at the cost of having carrier emitters either transmitting at high powers or…
Intelligent Reflecting Surface-Aided Joint Processing Coordinated Multipoint Transmission
Meng Hua, Qingqing Wu, Derrick Wing Kwan Ng +2
This paper investigates intelligent reflecting surface (IRS)-aided multicell wireless networks, where an IRS is deployed to assist the joint processing coordinated multipoint (JP-C…
