Abstract: Techniques for supporting distributed multiple-input multiple-output (MIMO) transmissions are described. In one design, a user equipment (UE) determines channel estimates for multiple cells and reports the channel estimates. The UE thereafter receives a data transmission sent by the multiple cells to the UE based on the channel estimates. The data transmission may include at least one data stream, and each data stream may be sent by one cell or the multiple cells to the UE. In another design, a UE determines first and second channel estimates for first and second cells, respectively, and reports the channel estimates. The UE then receives a first data transmission sent by the first cell to the UE based on the first channel estimate. The UE also receives a second data transmission sent by the second cell to another UE and steered away from the UE based on the second channel estimate.

Abstract: Un aparato (102) de comunicaciones inalámbricas, que comprende: un medio para proporcionar cobertura de una primera célula (104i) mediante un primer sistema (106i) de antena; un medio para proporcionar cobertura de una segunda célula (104j) mediante un segundo sistema (106j) de antena; un medio de procesamiento de datos para su transmisión a un dispositivo móvil de la primera célula utilizando los primero y segundo sistemas de antena caracterizado por: un medio de generación de unas primera y segunda señales de referencia para su transmisión en las primera y segunda células, respectivamente; y un medio de punzonado (102) de los datos para su transmisión en la primera célula cuando las primera y segunda señales de referencia no entren en colisión y de punzonado (102) de la primera señal de referencia cuando las primera y segunda señales de referencia entren en colisión, para hacer posible que el dispositivo móvil genere la segunda estimación de canal procedente de la segunda señal de referencia.

Abstract: Systems and methods for providing coverage to a first cell (104i) through a first antenna system (106i) and coverage to a second cell (104 j) through a second antenna system (106g). Data is also processed for transmission to a mobile device (108i) in the first cell using the first and second antenna systems.
