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…

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…
