Abstract: A method for wireless communications is provided. The method includes applying independent power controls to two or more carriers from a set of high speed packet access signals. The method includes monitoring power across the two or more carriers to determine power levels for the set of high speed packet access signals. The method also includes adjusting at least one of an open loop control, an inner loop control, or an outer loop control in view of the power levels for the set of packet access signals.

Abstract: A method is provided comprising generating data samples of received signals; demodulating the data samples to provide recovered symbols; deinterleaving the recovered symbols; decoding the recovered symbols to recover decoded data bits transmitted by an access terminal; encoding, interleaving and modulating the decoded data bits to form samples from the access terminal; and removing or cancelling a contribution of the access terminal from the data samples. Corresponding electronic hardware, software module and storage medium are also provided.

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 terminal de acceso (260) que se configura para la comunicación inalámbrica con una red de acceso (204) dentro de un sector (1032). El terminal de acceso (206) incluye un transmisor (2608) para transmitir un canal de tráfico inverso a la red de acceso (204), una antena (2614) para recibir señales desde la red de acceso (204), un procesador (2602) y memoria (2604) en comunicación electrónica con el procesador (2602). Las instrucciones almacenadas en la memoria (2604) implementan un método de determinar si una aprobación de asignación de la energía actual (1374) para un flujo (1216) en el terminal de acceso (206) se ha recibido desde la red de acceso (204). Si la aprobación de asignación de la energía actual (1374) sigue estando activa, se fija una asignación de la energía actual (1338a) para el flujo igual a la aprobación de asignación de la energía actual (1374). Si la aprobación de asignación de la energía actual (1374) no se ha recibido, determinar la asignación de la energía actual para el flujo; se determina una asignación de la energía actual (1338a) para el flujo.
