Abstract

Técnicas para la transmision de datos provenientes de antenas virtuales en lugar de antenas físicas. Cada antena virtual puede ser mapeada para algunas o todas las antenas físicas por medio de un mapeo diferente. El funcionamiento de diferentes conjuntos de por lo menos una antena virtual es evaluado sobre la base de una o más métricas tales como la calidad de la senal, el rendimiento, la proporcion general y similares. El conjunto de antena virtual con el mejor funcionamiento es seleccionado para ser utilizado. En caso de que la seleccion de antena virtual se realice por parte del receptor, entonces la informacion de estado de canal para el conjunto de la antena virtual realice por parte del receptor, entonces la informacion de estado de canal para el conjunto de la antena virtual seleccionado puede ser enviado hacia el transmisor. La informacion de estado de canal puede abarcar las antenas virtuales seleccionadas, la calidad de la senal por las proporciones para las antenas virtuales seleccionadas, una o más matriz STP decodificacion utilizados para formar las antenas virtuales seleccionadas, y similares. El transmisor y/o el receptor utilizan la antena virtual seleccionada para transmision de datos.
