Both decode-forward (DF) and amplify-forward (AF) are considered, and are compared with the point-to-point (P2P) scheme which does not use the relay. The question as to whether DF and AF can decrease the latency of communicating a number of bits with a given reliability requirement is addressed. Latency expressions for the three schemes are derived. Although both DF and AF use a block-transmission structure which sends the information over multiple transmission blocks, they can both achieve latencies lower th","authors_text":"Anas Chaaban, Aydin Sezgin","cross_cats":["math.IT"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.IT","submitted_at":"2014-09-09T10:49:15Z","title":"When Can a Relay Reduce End-to-End Communication Delay?"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1409.2674","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:b35a8e4a75b1f411bd68cc5913286f3b33b1bd2dd412cc7a93c452434bbc2776","target":"record","created_at":"2026-05-18T02:43:10Z","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":"2a8601a9f86b407cb772cd6ef866999e513d960a409a39a13c43b966bddaff27","cross_cats_sorted":["math.IT"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.IT","submitted_at":"2014-09-09T10:49:15Z","title_canon_sha256":"89f5cb6f19296d2569a232f993df432cce47f13ade5ad6cdf76a1eed54282946"},"schema_version":"1.0","source":{"id":"1409.2674","kind":"arxiv","version":1}},"canonical_sha256":"fd39f15470938f5794a43634574e88adbbf03df41049a821558368fb0340d998","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"fd39f15470938f5794a43634574e88adbbf03df41049a821558368fb0340d998","first_computed_at":"2026-05-18T02:43:10.023232Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T02:43:10.023232Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"K90zqyyWOEyoNwOB45Ayccknk8dbTfTW5APASjwOv6JLVUmfuucrbDM3rOFlqLbJNOrXQy8fLHiXBPS1M/LSCg==","signature_status":"signed_v1","signed_at":"2026-05-18T02:43:10.023711Z","signed_message":"canonical_sha256_bytes"},"source_id":"1409.2674","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:b35a8e4a75b1f411bd68cc5913286f3b33b1bd2dd412cc7a93c452434bbc2776","sha256:aa7faea313aa466c6c7baafd4a2e7c2c3e966703861c561533041683ff881059"],"state_sha256":"7ef95b9b517d5fedce240a9408747889ac177b147117ccea984004ace75a3179"}
