摘要

The pivotal characteristics of upcoming information communication networks are smart device interconnection and extensive global reach [1, 2]. Over the past four decades, significant advancements have been made, driven by the integration of technologies such as massive multiple input multiple output (MIMO) [3–5], orthogonal frequency division multiplexing (OFDM) [6–8], and polar codes [9–11]. These innovations have enabled the fifth generation (5G) networks to achieve impressive benchmarks, including Gbps-level transmission speeds, millisecond-level latency, and network capacities reaching into the millions [12–16]. Such developments form the essential infrastructure for the intelligent interconnection of everything.
