PDRS: A Fast Non-iterative Scheme for Massive Grant-free Access in Massive MIMO
Yihua Ma, Zhifeng Yuan, Weimin Li +1
Grant-free multiple-input multiple-output (MIMO) usually employs non-orthogonal pilots for joint user detection and channel estimation. However, existing methods are too complex fo…
LMMSE Processing for Cell-free Massive MIMO with Radio Stripes and MRC Fronthaul
Zhifeng Yuan, Yihua Ma, Guanghui Yu
Cell-free massive MIMO provides ubiquitous connectivity for multiple users, and implementation using radio stripes is very efficient. Compared with collocated massive MIMO, the maj…
Efficient Parallel Schemes for Cell-free Massive MIMO Using Radio Stripes
Yihua Ma, Zhifeng Yuan, Guanghui Yu +1
Cell-free massive MIMO provides ubiquitous connectivity for multiple users, and implementation using radio stripes is very efficient. This paper proposes a parallel scheme for radi…
White Paper on Critical and Massive Machine Type Communication Towards 6G
Nurul Huda Mahmood, Stefan Böcker, Andrea Munari +28
The society as a whole, and many vertical sectors in particular, is becoming increasingly digitalized. Machine Type Communication (MTC), encompassing its massive and critical aspec…
Contention-based Grant-free Transmission with Independent Multi-pilot Scheme
Zhifeng Yuan, Weimin Li, Zhigang Li +2
Contention-based grant-free transmission is very promising for future massive machine-type communication (mMTC). In contention-based transmission, the random pilot collision is a c…
