摘要

In this letter, we take the lead in investigating the average AoI performance for polar coded status updates over the additive white Gaussian noise (AWGN) channels. Compared with the non-automatic repeat request (non-ARQ) scheme, the hybrid ARQ with chase combining (HARQ-CC) scheme can effectively reduce the average AoI, especially in the low signal-to-noise ratio (SNR) region. Then, to improve th...
