Patent ID: 8526516

Claim:
In a multiple input multiple output (MIMO) wireless communication system, a method for error correction, comprising: receiving an original signal in an initial MIMO format; detecting an error in the original signal; notifying a transmitter of the error detected in the original signal; receiving a new retransmitted signal in a first retransmitted MIMO format, different from the initial MIMO format, the new retransmitted signal including at least a fraction of encoded bits of the original signal; correcting the original signal by applying the new retransmitted signal to the original signal; sending feedback about the original signal to transmitter, wherein the transmitter switches the first retransmitted MIMO format from the initial MIMO format according to the sent feedback, wherein the initial MIMO format and the first MIMO format are chosen from the group including: closed-loop MIMO, open-loop MIMO, multi-user MIMO, single-user MIMO, non-cooperative MIMO, cooperative MIMO, non-CDD MIMO, CDD MIMO, or a combination thereof, and wherein the initial MIMO format and the first retransmitted MIMO format have a different MIMO rate.
