Contention-based nonorthogonal massive access with massive MIMO

China Communications, 2020
The sporadic communication character of massive machine-type communication systems provides natural advantages to utilize the principle of compressive sensing (CS). However, due to the high computational complexity of CS algorithms, CS-based contention-free access schemes have limited scalability and high computational complexity for massive access ...

Mixed Massive Random Access

2020 IEEE 20th International Conference on Communication Technology (ICCT), 2020
In this paper, the massive random access scenario that a part of users transmit both common and user-specific information and the others transmit only common information is considered, and a mixed massive random access scheme is proposed. In the proposed scheme, the common information is transmitted by unsourced random access (URA) technique, and the ...

On the design of massive access

2017 9th International Conference on Wireless Communications and Signal Processing (WCSP), 2017
In this paper, we design a fully non-orthogonal communication framework for spectral-efficient massive access. Firstly, we propose a non-orthogonal channel estimation (NOCE) method, which can achieve a balance between channel state information (CSI) accuracy and the length of pilot sequence. Then, we present a massive multiple-input multiple-out (MIMO)

Random Access with Massive-Antenna Arrays

2016 IEEE 83rd Vehicular Technology Conference (VTC Spring), 2016
Recently massive multi-input multi-output (MIMO) techniques have attracted growing research interest. However, most existing works assume centralized control, which may involve a heavy overhead as the number of users also becomes massive. In this paper, we focus on random-access massive MIMO systems.
