Web19 okt. 2024 · The optimization strategy can be applied into fading channels. Finally, numerical simulation results show that the proposed SMP-HARQ could improve throughput performance compared to existing HARQ schemes for IoT applications over both the AWGN and Rayleigh fading channels, particularly in the low SNR regions. WebUplink HARQ operation is asynchronous for NB-IoT UEs, BL UEs or UEs in enhanced coverage except for the repetitions within a bundle. For NB-IoT UEs, BL UEs or UEs in enhanced coverage, the parameter UL_REPETITION_NUMBER provides the number of transmission repetitions within a bundle.
