Data packets scheduling and encoding method for multicast automatic repeat request communication system, involves transmitting one of composite data packets to two receivers by sender.
2006 (English)Patent (Other (popular science, discussion, etc.))
NOVELTY - The method involves obtaining feedback information from two receivers indicating received data packets, and forming a composite data packet as a weighted linear combination of regular data packets. Coding weights of a weight vector are adapted based on the feedback information for each of the composite data packet, such that the composite packet represents a linear combination of the regular packets for the receivers of the data packet previously received by the receivers during a multicast session. One of the composite data packets is transmitted to the receivers by a sender. USE - Method for scheduling and encoding data packets for transmission in a multicast session from a sender to two receivers in a multicast automatic repeat request (ARQ) communication system. Can also be used in a cellular system with a base station in communication with a set of mobile terminals. ADVANTAGE - The method effectively schedules and encodes the data packets for transmission in the multicast session from the sender to the receivers in the multicast automatic repeat request (ARQ) communication system. The method enables improved throughput efficiency for the reliable multicast, and provides deterministically decodable re-transmission scheme. The method provides highly throughput-efficient strategy for reliable multicasting. The method efficiently provides the multicast strategy that enables enhanced throughput, reduced delay and/or reduced energy consumption. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a sender for use in a multicast automatic repeat request (ARQ) communication system, comprising an arrangement for scheduling and encoding data packets for transmission in a multicast session from the sender to two receivers. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic flow diagram of a method for scheduling and encoding regular data packets into a composite data packet.
