We first propose two coding schemes for the discrete memoryless case: simultaneous encoding for the sub-messages in the first one and superposition encoding in the second one, both with rate splitting and Gel'fand-Pinsker coding. The corresponding achievable rate regions are established. Moreover, for the Gaussian case, we focus on the simultaneous encoding scheme and propose an \\emph{active interference cancel","authors_text":"Jinhua Jiang, Lili Zhang, Shuguang Cui","cross_cats":["math.IT"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.IT","submitted_at":"2011-04-19T07:37:26Z","title":"Interference Channel with State Information"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1104.3661","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:abb30a76d6e57a8781c5cb338e57f99ea677039d2de3f9238b8ec28d9ed32c67","target":"record","created_at":"2026-05-18T02:22:02Z","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":"01a12c1617e733dbf00f8c30305ac716fdd164672bb6485775e0f76f9c23a1a2","cross_cats_sorted":["math.IT"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.IT","submitted_at":"2011-04-19T07:37:26Z","title_canon_sha256":"e6458cb70e5c17b34b233a7a3ea14489c239c40d894605d0f8b4f8433072a15d"},"schema_version":"1.0","source":{"id":"1104.3661","kind":"arxiv","version":2}},"canonical_sha256":"ddcfe768162457654fd044cb6abc8d792aaa7cd28ae74597a66743e284d81ecd","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"ddcfe768162457654fd044cb6abc8d792aaa7cd28ae74597a66743e284d81ecd","first_computed_at":"2026-05-18T02:22:02.270758Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T02:22:02.270758Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"+0GWwd9ChYsG7uAkByCsRbJboPmk6t6vJuTSYqsgfTG28UEX0aQPCg5CFbRG1bk8Pciswa2sgwfY+V/vmil6DQ==","signature_status":"signed_v1","signed_at":"2026-05-18T02:22:02.271511Z","signed_message":"canonical_sha256_bytes"},"source_id":"1104.3661","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:abb30a76d6e57a8781c5cb338e57f99ea677039d2de3f9238b8ec28d9ed32c67","sha256:b7abc731738640234ad77a8cbd6a4cc367d86a874d522484cdd0d9e8bd61b896"],"state_sha256":"7037491eb1105bb435d272cc3fcae48071747096bb306302671ab323c2d477ec"}
