Assuming that the quality of all user channels is available to a central controller, a simple scheme which maximizes the utility function defined as the sum logarithm throughput of all users has been shown to guarantee proportional fairness. However, to acquire the channel quality information may consume substantial amount of resources. In this work, it is assumed that probing the quality of each user's channel takes a fraction of the coherence time, so that the amount of time for data trans","authors_text":"(2) Northewstern University, China, Dongning Guo (2) ((1) Tsinghua University, Hui Zhou (1), Pingyi Fan (1), US)","cross_cats":["math.IT"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.IT","submitted_at":"2010-09-14T09:39:52Z","title":"Joint Channel Probing and Proportional Fair Scheduling in Wireless Networks"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1009.2602","kind":"arxiv","version":1},"verdict":{"created_at":null,"id":null,"model_set":{},"one_line_summary":"","pipeline_version":null,"pith_extraction_headline":"","strongest_claim":"","weakest_assumption":""}},"verdict_id":null}}],"author_attestations":[],"timestamp_anchors":[],"storage_attestations":[],"citation_signatures":[],"replication_records":[],"corrections":[],"mirror_hints":[],"record_created":{"event_id":"sha256:e11d61f3ffcd0502a9953666088e65ccb448cf6ca56fc5de949cca574c3e9c0c","target":"record","created_at":"2026-05-18T04:40:56Z","signer":{"key_id":"pith-v1-2026-05","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","signer_id":"pith.science","signer_type":"pith_registry"},"payload":{"attestation_state":"computed","canonical_record":{"metadata":{"abstract_canon_sha256":"ce9ceeb434d4c918aef8cf32b46dbe531422275458ebf0ed72f2830df7fe94b9","cross_cats_sorted":["math.IT"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.IT","submitted_at":"2010-09-14T09:39:52Z","title_canon_sha256":"c648c1632f79c495525219e942aa186b8c045d1cd184b144ca9ae7d9b654f585"},"schema_version":"1.0","source":{"id":"1009.2602","kind":"arxiv","version":1}},"canonical_sha256":"1e3b8631bca3bf45fd200e8dbcfac4a972390b3cdceee9ce6a5be027060708a3","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"1e3b8631bca3bf45fd200e8dbcfac4a972390b3cdceee9ce6a5be027060708a3","first_computed_at":"2026-05-18T04:40:56.725969Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T04:40:56.725969Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"oUTSRD69+7so6fNB0Y7vNGTls1PorqhsWTSWQ0jAI3ZwB0d9PeV+EOyks+B9q6rmiNh2pDj2DE3kb8SJtQwmBw==","signature_status":"signed_v1","signed_at":"2026-05-18T04:40:56.726397Z","signed_message":"canonical_sha256_bytes"},"source_id":"1009.2602","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:e11d61f3ffcd0502a9953666088e65ccb448cf6ca56fc5de949cca574c3e9c0c","sha256:5690f6510157e58414834c71692d173675941b63c268ffd6e4f94f040d6a1163"],"state_sha256":"ee960833cdee2ae13c738213c543268f45cf81d30b48289df59b4fde2a20197c"}
