In practical 5G networks, the gNB does not directly observe the destination-side Age of Information (AoI) and must make scheduling decisions under stringent slot-level runtime constraints. In this paper, we develop a low-complexity AoI-aware scheduling policy for 5G cellular under limited observability. We first design a low-complexity estimator that infers UE-side packet timestamps and destination-side AoI from gNB-visible observat"},"claims":{"count":4,"items":[{"kind":"strongest_claim","text":"The LC estimator and MW-LC achieve performance close to a richer estimator-based AoI policy from the literature.","source":"verdict.strongest_claim","status":"machine_extracted","claim_id":"C1","attestation":"unclaimed"},{"kind":"weakest_assumption","text":"The low-complexity estimator can accurately infer UE-side packet timestamps and destination-side AoI from gNB-visible observations under realistic 5G slot-level constraints.","source":"verdict.weakest_assumption","status":"machine_extracted","claim_id":"C2","attestation":"unclaimed"},{"kind":"one_line_summary","text":"A low-complexity estimator and MW-LC Max-Weight policy enable practical AoI-aware uplink scheduling in 5G under limited observability, matching richer policies in NetSim and MATLAB simulations.","source":"verdict.one_line_summary","status":"machine_extracted","claim_id":"C3","attestation":"unclaimed"},{"kind":"headline","text":"A low-complexity estimator enables practical Age-of-Information scheduling in 5G despite limited observability.","source":"verdict.pith_extraction.headline","status":"machine_extracted","claim_id":"C4","attestation":"unclaimed"}],"snapshot_sha256":"0b2b735faaf1870796b5831d005f5dea252a056223c1b706ea5877c757b6a79c"},"source":{"id":"2605.13012","kind":"arxiv","version":1},"verdict":{"id":"2c25ae09-aaa9-4193-9f65-84fe091e229d","model_set":{"reader":"grok-4.3"},"created_at":"2026-05-14T18:29:31.679053Z","strongest_claim":"The LC estimator and MW-LC achieve performance close to a richer estimator-based AoI policy from the literature.","one_line_summary":"A low-complexity estimator and MW-LC Max-Weight policy enable practical AoI-aware uplink scheduling in 5G under limited observability, matching richer policies in NetSim and MATLAB simulations.","pipeline_version":"pith-pipeline@v0.9.0","weakest_assumption":"The low-complexity estimator can accurately infer UE-side packet timestamps and destination-side AoI from gNB-visible observations under realistic 5G slot-level constraints.","pith_extraction_headline":"A low-complexity estimator enables practical Age-of-Information scheduling in 5G despite limited observability."},"references":{"count":17,"sample":[{"doi":"","year":2011,"title":"Minimizing age of information in vehicular networks,","work_id":"1e872526-ae65-4482-8cf1-ce86d64dfac3","ref_index":1,"cited_arxiv_id":"","is_internal_anchor":false},{"doi":"","year":2017,"title":"Update or wait: How to keep your data fresh,","work_id":"8efddd6e-c2ff-4990-83b3-d0e6237a8e5f","ref_index":2,"cited_arxiv_id":"","is_internal_anchor":false},{"doi":"","year":2021,"title":"Age of information: An introduction and survey,","work_id":"007a3c93-0e5d-43cc-b811-13d1c16d32f2","ref_index":3,"cited_arxiv_id":"","is_internal_anchor":false},{"doi":"","year":2019,"title":"Scheduling algorithms for optimizing age of information in wireless networks with throughput constraints,","work_id":"1a2cbcde-8aa7-4f68-89c8-d55310fba18a","ref_index":4,"cited_arxiv_id":"","is_internal_anchor":false},{"doi":"","year":2025,"title":"AoI-QPS: Age-of- information aware efficient queue-proportional scheduling,","work_id":"e1fbaa87-5925-4372-949a-c2b7234a8d54","ref_index":5,"cited_arxiv_id":"","is_internal_anchor":false}],"resolved_work":17,"snapshot_sha256":"b08e40d6ae3df28b3092f65d953c99c817e6def26ad404ea34f03983d9046ff1","internal_anchors":0},"formal_canon":{"evidence_count":2,"snapshot_sha256":"831ee4de153d2c59c7b2572c3110c9cdc5aeed9f00f70676c6d75c3c3cb1df56"},"author_claims":{"count":0,"strong_count":0,"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"builder_version":"pith-number-builder-2026-05-17-v1"}
