Balancing Queueing and Retransmission: Latency-Optimal Massive MIMO Design.
IEEE Transactions on Wireless Communications(2020)
摘要
One fundamental challenge in 5G URLLC is how to optimize massive MIMO systems for achieving low latency and high reliability. A natural design choice to maximize reliability and minimize retransmission is to select the lowest allowed target error rate. However, the overall latency is the sum of queueing latency and retransmission latency, hence choosing the lowest target error rate does not always...
