While most existing works focus on physical layer approaches to exploit its capacity gain, the benefits of two-way relaying on upper layers are much less investigated. In this paper, we study the cross-layer design and optimization for delay quality-of-service (QoS) provisioning in two-way relay systems. Our goal is to find the optimal transmission policy to maximize the weighted sum throughput of the two users in the physical layer while guaranteeing the individual statistical delay-QoS requ","authors_text":"Cen lin, Meixia Tao, Yuan Liu","cross_cats":["math.IT"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.IT","submitted_at":"2012-05-15T07:16:31Z","title":"Cross-Layer Optimization of Two-Way Relaying for Statistical QoS Guarantees"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1205.3277","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:be530433d8b430ddd412be812b160a913f2cdd38d2e286f2ad78968b001f7a63","target":"record","created_at":"2026-05-18T03:55:36Z","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":"c141d41835b07db7dfd63e829f9211d9d2f9c8772cdae44f8cc0283c030caa08","cross_cats_sorted":["math.IT"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.IT","submitted_at":"2012-05-15T07:16:31Z","title_canon_sha256":"f49e718b52c4351140237101f73f3a79d9a53ce1e7b97316704037263d31663a"},"schema_version":"1.0","source":{"id":"1205.3277","kind":"arxiv","version":1}},"canonical_sha256":"28174a2997ebd0485889ef50106c88aafe4839b512fae198b09fb6d7cf6473e1","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"28174a2997ebd0485889ef50106c88aafe4839b512fae198b09fb6d7cf6473e1","first_computed_at":"2026-05-18T03:55:36.440746Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T03:55:36.440746Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"lJWZPcN5ihLNrNET50ULEjWV7duH2YwAzOQFURMKNA/OVmMfRqNXkKRVyxxNiQGUbmF/vRz99gFvQ3vl8lG8Bw==","signature_status":"signed_v1","signed_at":"2026-05-18T03:55:36.441357Z","signed_message":"canonical_sha256_bytes"},"source_id":"1205.3277","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:be530433d8b430ddd412be812b160a913f2cdd38d2e286f2ad78968b001f7a63","sha256:253d2ba2750f71f0abc487bd8f1c97e7174a7f809a68babdaf5f51d0f792d114"],"state_sha256":"2a4f42a10f1b2e8965851ca8e86aef9d5aa2ddaebf1f0cf44ad985c8a7a7ae0e"}
