Hybrid ARQ (HARQ) protocol takes advantage of the retransmissions in ARQ to enable the receiver to decode the currently received data by combining it with all the previously received transmissions that were not successfully decoded. Each successive retransmission improves the probability of correctly decoding the data. To support HARQ, the receiver is required to store the previously received unsuccessful transmissions for combining with future retransmissions. The storage of the previously received unsuccessful transmissions can be very large depending on type of the HARQ protocol used. A method and apparatus are disclosed that enable reduced memory storage requirements while maintaining the HARQ performance requirements. The reduced memory requirements result in reduced cost, reduced power consumption and lowered cost."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and apparatus for reduced HARQ buffer storage","description":"Automatic Repeat Request (ARQ) protocol is used in many modern telecommunication systems for improved link level reliability.
