    Abstract: Techniques for reporting acknowledgement (ACK) information and channel quality indication (CQI) information in a wireless communication system are described. A user equipment (UE) may be able to receive data from up to two cells with dual-cell operation. The UE may determine CQI information for a first cell, determine CQI information for a second cell, and send the CQI information for both cells on a feedback channel with a single channelization code. The UE may process a control channel from each cell and, if control information is received from the cell, may further process a data channel from the cell to receive data sent to the UE. The UE may determine ACK information for each cell based on processing results for the data and control channels from that cell. The UE may send the ACK information for both cells on the feedback channel with the single channelization code.

    Abstract: Un procedimiento para habilitar la diversidad de transmisión con formación de haz de enlace ascendente, que comprende: recibir (604), mediante un dispositivo de comunicación inalámbrica, WCD (510, 1100), un vector de ponderación de formación de haz en respuesta a la transmisión mediante el WCD (510, 1100) de al menos un primer canal piloto y al menos un segundo canal piloto; aplicar (606) el vector de ponderación de formación de haz recibido a al menos uno del primer canal piloto, uno o más canales de datos y uno o más canales de control, y opcionalmente aplicar (610) un segundo vector de ponderación de formación de haz obtenido a partir del vector de ponderación de formación de haz recibido al segundo canal piloto, en el que el vector de ponderación de formación de haz se determina para maximizar una relación de señal a ruido para al menos uno de los uno o más canales de datos y para al menos uno de los uno o más canales de control; y transmitir (612), usando dos o más antenas (516), el primer canal piloto, el segundo canal piloto, al menos uno de los uno o más canales de datos, y al menos uno de los uno o más canales de control, y en el que el primer canal piloto, el al menos uno de los uno o más canales de datos, y el al menos uno de los uno o más canales de control se transmiten usando una antena virtual dominante de las dos o más antenas (516) y el segundo canal piloto es transmitido usando una antena virtual más débil de las dos o más antenas (516).
