Method and apparatus for point-to-multipoint data communication with arq

摘要

The method involves delivering data to multiple wireless destinations by the issuing of a negative acknowledge message (418) from a receiving terminal upon detecting a second outstanding block error (416). The transmitting terminal sends an error correction block for all the blocks up to but not including the block with the second detected error, which increases the throughput. Each receiver is independent of the other receivers and decodes the incoming blocks. Every receiver performs the error detection function on every received block and detects whether or not the block has been received correctly.
