It is assumed that there are some sub-channels in each cell which should be allocated among some users. Also, each user is subjected to a power constraint. The underlying problem is a non-convex mixed integer non-linear optimization problem which does not have a trivial solution. To solve the problem, having fixed the consumed power of each user, and assuming low co-channel interference region, the sub-channel allocation problem is reformulate into a more ","authors_text":"Ata Khalili, Soroush Akhlaghi","cross_cats":["cs.IT","math.IT"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"eess.SP","submitted_at":"2017-11-28T20:23:51Z","title":"Power Control and Scheduling In Low SNR Region In The Uplink of Two Cell Networks"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1711.10538","kind":"arxiv","version":2},"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:f62fd13dc3217c81b28c222d15622853971e70381526f337dcbfe6ebb9a90a4d","target":"record","created_at":"2026-05-17T23:41:22Z","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":"eff3ffba5b28cf84bfddcb1e123612fcacf2822f51d7095ce7fbeda6e65012fd","cross_cats_sorted":["cs.IT","math.IT"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"eess.SP","submitted_at":"2017-11-28T20:23:51Z","title_canon_sha256":"2211e8b98db3d331de86f315164685b6822263ef4ac0ce9c73ce86df5b0ce628"},"schema_version":"1.0","source":{"id":"1711.10538","kind":"arxiv","version":2}},"canonical_sha256":"2ef3c4f56a1751311a0f25e9a1c93c0a06af9e54787eb72991c847d3cee8f50a","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"2ef3c4f56a1751311a0f25e9a1c93c0a06af9e54787eb72991c847d3cee8f50a","first_computed_at":"2026-05-17T23:41:22.223783Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-17T23:41:22.223783Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"xDEELeYdJlKXVF9XtmVPZNc0uAGWUrpe+ap/idGoYL/BTFN6YshajSPSYbtdTj+l7PyHj35kYB5zNt3VugkVCw==","signature_status":"signed_v1","signed_at":"2026-05-17T23:41:22.224274Z","signed_message":"canonical_sha256_bytes"},"source_id":"1711.10538","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:f62fd13dc3217c81b28c222d15622853971e70381526f337dcbfe6ebb9a90a4d","sha256:07f0f80617b5af691f14a64276ac170260ea27572646ea9a031fdf29bffdf6a4"],"state_sha256":"11ba94007a4ffc39670b490cb068452b78f1b08fee2f52db50cdd653c8639f08"}
