Open the CIPO recordAbstract From the Canadian patent
To select a transmission mode to use for a data transmission via a MIMO channel from station A to station B, station A obtains channel information used for spatial processing and determines the age of this information. Station A selects one of multiple transmission modes based on the age of the channel information and possibly other information (e.g. the fading characteristic of the MIMO channel). To select rate(s) to use for the data transmission, station A obtains channel state information (CSI) indicative of the received signal quality for the MIMO channel e.g. received SNRs or , "initial" rates. Station A determines the age of the CSI and selects one or more "final" rates based …
