—This paper analyzes wireless network control for remote estimation of linear time-invariant dynamical systems under various Hybrid Automatic Repeat Request (HARQ) packet retransmission schemes. In conventional HARQ, packet reliability increases gradually with additional packets; however, each retransmission maximally increases the Age of Information and causes severe degradation in estimation mean squared error (MSE) performance. We optimize standard HARQ schemes by allowing partial…

It is shown that the minimum error covariance estimator is time-varying, stochastic, and it does not converge to a steady state, and the architecture is independent of the communication protocol and can be implemented using a finite memory buffer if the delivered packets have a finite maximum delay.
