Slow and fast adaptive modulation and coding for uplink massive MIMO systems with packet retransmission

open access: yesIET Communications, Volume 16, Issue 9, Page 915-928, June 2022., 2022
Abstract Here, the authors consider the uplink of a cellular massive multiple‐input multiple‐output (MIMO) system with maximum ratio combiner (MRC) at base stations (BSs). To achieve a better QoS provisioning, users in the cells employ link adaptation using adaptive modulation and coding (AMC) in conjunction with packet retransmission.

Cloud‐edge collaboration based peer to peer services redirection strategy for passive optical network

open access: yesIET Communications, Volume 16, Issue 8, Page 902-914, May 2022., 2022
Abstract With the increasing number of fibre access users, P2P file sharing download traffic has gradually become one of the enormous bandwidth consumptions for the access network. Localizing traffic could save bandwidth and reduce latency, but it caused optical line terminal (OLT) overload problems.
