The method includes determining whether a user equipment (UE) is a legacy UE or a non-legacy UE, determining non-D2D sub-frames which will collide with D2D sub-frames if the UE is the non-legacy UE, determining whether the non-D2D sub-frames are available, and scheduling a new HARQ packet for the UE in the determined non-D2D sub-frames if the determined non-D2D sub-frames are available."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Apparatus and method for collision avoidance between hybrid automatic repeat request transmission and device to device transmission in communication system supporting device to device scheme","description":"A method for avoiding a collision between a hybrid automatic repeat request (HARQ) transmission and a device to device (D2D) transmission by a base station (BS) in a communication system supporting a ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9629174","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.
