The method can include the victim node receiving downlink signal information from an aggressor node. The victim node can estimate a channel impulse response for a channel between the aggressor node and the victim node using the downlink signal information. The victim node can estimate an inter-node interference signal for the channel using the downlink signal information and the channel impulse response. The victim node can receive an uplink signal from a wireless device, wherein the downlink signal information is received prior to the reception of the uplink signal. The victim node can subtract the estimated inter-node interference signal from the uplink signal to form an inter-node interference compensated uplink signal to substantially cancel the inter-node interference from the aggressor node in the uplink signal."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Inter-node interference cancellation","description":"A method for cancelling inter-node interference at a victim node is disclosed, which method may be executed as instructions on a machine, where the instructions are included on at least one computer r","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9699731","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
