A retransmission scheme in IEEE 802.11be synchronized multi-link WLANs

摘要

A novel retransmission scheme, considering both trans-mission rate and frame error rate, is proposed to alleviate the inefficien-cies caused by head-of-line blocking and null padding problems duringretransmission in IEEE 802.11be synchronous multi-link wireless localarea networks. Simulation results show that the proposed scheme improvesthroughput by up to 200% over the legacy scheme by reallocating lostsubframes and adding effective duplicate subframes to multiple links.
