A user terminal supports multiple spatial multiplexing (SM) modes such as a steered mode and a non-steered mode. For data transmission multiple data , streams are coded and modulated in accordance with their selected rates to obtain multiple data symbol streams. These streams are then spatially processed in accordance with a selected SM mode (e.g. with a matrix of steering vectors for the steered mode and with the identity matrix for the nonsteered mode) to obtain multiple transmit symbol streams for transmission from multiple antennas. For data reception, multiple received symbol streams are spatially processed in accordance with the selected SM mode (e.g. with a matrix of …

Why it's free to use
- Filed October 24, 2003 and granted February 12, 2013. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended October 24, 2023.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by October 24, 2025.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
