However, the use of large antenna arrays with beamforming demands precise beam-alignment between transmitter and receiver, and may entail huge overhead in mobile environments. This paper investigates the design of an optimal interactive beam-alignment and data communication protocol, with the goal of minimizing power consumption under a minimum rate constraint. The base-station selects beam-alignment or data communication and the beam parameters, based on feedback from the u","authors_text":"Muddassar Hussain, Nicolo Michelusi","cross_cats":["math.IT"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.IT","submitted_at":"2018-05-16T01:38:13Z","title":"Energy-Efficient Interactive Beam-Alignment for Millimeter-Wave Networks"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1805.06089","kind":"arxiv","version":4},"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:c9d5a2e48174fad5468e28174ef1581471f006e9ee85a6a651d6c04b3394a962","target":"record","created_at":"2026-05-17T23:58:48Z","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":"2ce654be134e7751a96f9d504b95b56bb83b6a0c87d568e70c2632d2836c6bad","cross_cats_sorted":["math.IT"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.IT","submitted_at":"2018-05-16T01:38:13Z","title_canon_sha256":"5e811b4f7b11c3f8d8f4385688c4a7541c1135a986de967cfee82f020c204fac"},"schema_version":"1.0","source":{"id":"1805.06089","kind":"arxiv","version":4}},"canonical_sha256":"c85784e20446d8c0e5314f77bb9e93aaaf15d3782fae3a647f98327760d60199","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"c85784e20446d8c0e5314f77bb9e93aaaf15d3782fae3a647f98327760d60199","first_computed_at":"2026-05-17T23:58:48.005718Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-17T23:58:48.005718Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"KX2tEYsbn6n6k0ASZef3ryxT4u4L3J4KmMjwnwELPavAqMzSOHexhUWyi1+9WBR2c8NG254bTizqBMFNgrw1Bw==","signature_status":"signed_v1","signed_at":"2026-05-17T23:58:48.006859Z","signed_message":"canonical_sha256_bytes"},"source_id":"1805.06089","source_kind":"arxiv","source_version":4}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:c9d5a2e48174fad5468e28174ef1581471f006e9ee85a6a651d6c04b3394a962","sha256:1e0ceee0e8828f2c2a669e90e57ae3d4ce894ff4d30c83f9c6dd113b3dd3d250"],"state_sha256":"cdb40f37c94a6a745444654ee7e34c89f546be240e4bc1da31b7822ade581f93"}
