SYSTEM AND METHOD OF OPERATING A MIMO SYSTEM
First Claim
1. A MIMO system comprising a first apparatus (10) having means (M1-4) for transmitting a plurality of encoded data streams and a second apparatus (12) having means (DM1-4) for receiving and means (DC1-4) for decoding the encoded data streams, the performance of the second apparatus (12) being dependent on the order in which the received encoded data streams are decoded, further comprising, at the first apparatus (10), means (52) for determining information relating to the decoding order and means (50) for transmitting the determined information to the second apparatus (12), and at the second apparatus (12), means (20) for selecting a decoding order in response to the information relating to the decoding order received from the transmitting apparatus (10).

Abstract
A MIMO system comprising a transmitting station (10) for transmitting a plurality of encoded data streams and a receiving station (12) for receiving and for decoding the encoded data streams, the performance of the receiving station being dependent on the order in which the received encoded data streams are decoded, wherein information relating to the decoding order is determined at the transmitting station and is signalled to the receiving station.

- 4. A method of operating a MIMO system comprising a first apparatus (10) transmitting a plurality of encoded data streams, and a second apparatus (12) receiving and decoding the encoded data streams, the performance of the second apparatus (12) being dependent on the order in which the received data streams are decoded, further comprising the first apparatus (10) determining information relating to decoding order and signalling the information to the second apparatus (12), and the second apparatus (12) selecting a decoding order in response to receiving the information relating to decoding order.
- 7. An apparatus (10) for transmitting data in a MIMO system, comprising means (M1-4) for transmitting a plurality of encoded data streams to a receiving apparatus (12), means (52) for determining information relating to decoding order of the data streams, and means (50) for transmitting the determined information to the receiving apparatus (12).
- 12. An apparatus (12) for receiving from a transmitting apparatus (10) in a MIMO system, comprising means (DM1-4) for receiving a plurality of encoded data streams, decoding means (DC1-4) for decoding the plurality of encoded data streams, wherein the performance of the decoding means (DC1-4) is dependent on the order in which the encoded data streams are decoded, and means (20) for selecting a decoding order in response to information relating to decoding order received from the transmitting apparatus (10).
