Contention-based Grant-free Transmission with Extremely Sparse Orthogonal Pilot Scheme
Zhifeng Yuan, Zhigang Li, Weimin Li +1
Due to the limited number of traditional orthogonal pilots, pilot collision will severely degrade the performance of contention-based grant-free transmission. To alleviate the pilo…

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…
