We consider a time-division duplex (TDD) system where transmitters acquire their channel state information (CSI) by decoding the pilot sequences sent by the receivers. Since global CSI knowledge is required for IA, the transmitters have also to exchange their estimated CSIs over a backhaul of limited capacity (i.e. imperfect case). Under this setting, we characterize in this paper the stability region of the system under both the imper","authors_text":"Anthony Ephremides, Matha Deghel, M\\'erouane Debbah, Mohamad Assaad","cross_cats":["math.IT"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.IT","submitted_at":"2016-05-03T12:43:55Z","title":"Queueing Stability and CSI Probing of a TDD Wireless Network with Interference Alignment"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1605.00873","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":"sha256:079fd8d2aa78f8871f392629fdd291ce8c48882b712294f904c79b296a012e36","target":"record","created_at":"2026-05-18T00:57:49Z","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":"c6bfa7eb6143add373af0ccb186f57e1841da6ce9b303a9f6f25e697f69fca70","cross_cats_sorted":["math.IT"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.IT","submitted_at":"2016-05-03T12:43:55Z","title_canon_sha256":"c4724b7c68caddb4af9a4d13068e9d24901c263b1e8a8b8bf890866de617c5a7"},"schema_version":"1.0","source":{"id":"1605.00873","kind":"arxiv","version":1}},"canonical_sha256":"38f58f6caea75243245b22c94f9690f37e4601144a113281b5fb7bdcd631ff3b","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"38f58f6caea75243245b22c94f9690f37e4601144a113281b5fb7bdcd631ff3b","first_computed_at":"2026-05-18T00:57:49.653567Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:57:49.653567Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"JG83xfurFlQQQH5cAlzX1AJEIsV6v2ZS2wsLRvx/HQpSt4RFRHHQNBW1EGuZYt7vEbW+8gr/T1VqFOArkQe5Ag==","signature_status":"signed_v1","signed_at":"2026-05-18T00:57:49.654233Z","signed_message":"canonical_sha256_bytes"},"source_id":"1605.00873","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:079fd8d2aa78f8871f392629fdd291ce8c48882b712294f904c79b296a012e36","sha256:c3c5b4781cae7211f8f8009a3004a07d106f12f4738abd3b39fd01c4b25eca3f"],"state_sha256":"de7ec32a5cfb75c05eae6037f412f2f8030ce6f6d90c6a138b829fc77594f878"}
