Mimo wireless data transmission system

Abstract

A MIMO wireless data transmission system including a data arrangement in which data to be sent is divided for each transmission stream of MIMO with adding an error detection code thereto and thereby resending a subframe's worth of data when an error occurred at the time of resending. It therefore becomes to avoid the same frame being sent again at the time of resending.

1 . A MIMO wireless data transmission system, in which a first wireless device sends a data using MIMO and a second wireless device receives the data, wherein the first wireless device divides all of or a part of a send data into a plurality of subframes, adds an error detection code to each of the subframes, sends each of the subframes using a stream of an eigen-mode transmission, and resends a subframe having an error of the send data, the subframe being notified from the second wireless device that received the send data, and wherein the second wireless device detects an error of the respective subframes sent from the first wireless device, and notifies the first wireless device of a subframe in which an error occurred.
