Abstract
For use in a multicast wireless communication network comprising a plurality of base stations, various methods for encoding retransmissions to a plurality of mobile stations are provided. Each method includes transmitting a plurality of data packets to the plurality of mobile stations. Each method also includes creating at least one redundancy packet by using at least two of the plurality of data packets and binary XOR addition. Each method further includes transmitting at least one redundancy packet to the plurality of mobile stations.
Claims21
For use in a multicast wireless communication network comprising a plurality of base stations, a method for encoding retransmissions to a plurality of mobile stations, the method comprising the steps of:
- transmitting a plurality of data packets to the plurality of mobile stations;
- creating at least one redundancy packet by using at least two of the plurality of data packets and binary XOR addition;
- and
- transmitting the at least one redundancy packet to the plurality of mobile stations.
A multicast wireless communication network comprising a plurality of base stations, each of the base stations capable of encoding retransmissions to a plurality of mobile stations, each base station configured to:
- transmit a plurality of data packets to the plurality of mobile stations;
- create at least one redundancy packet by using at least two of the plurality of data packets and binary XOR addition;
- and
- transmit the at least one redundancy packet to the plurality of mobile stations.
A mobile station capable of accessing a multicast wireless communication network comprising a plurality of base stations, the mobile station configured to:
- receive from one of the base stations a plurality of data packets;
- receive from the one base station at least one redundancy packet, the at least one redundancy packet created by using at least two of the plurality of data packets and binary XOR addition;
- and
- recover a data packet received in error from the one base station by using the at least one redundancy packet, a subset of the plurality of data packets and XOR binary addition.
