Abstract: Un procedimiento para la comunicación inalámbrica, que comprende: proporcionar L símbolos de señales a cada uno de una pluralidad de ensanchadores (S1...SM), donde L > 1; con cada uno de la pluralidad de ensanchadores (S1...SM), ensanchar dichos L símbolos de señales para obtener un conjunto respectivo de L símbolos de salida, obteniéndose cada conjunto de L símbolos de salida mediante el ensanchamiento de los L símbolos de señales con una matriz de ensanchamiento (912) correspondiente al ensanchador respectivo; y asignar el conjunto respectivo de L símbolos desde salida de cada ensanchador a L unidades de recursos dentro de uno de múltiples bloques de tiempo frecuencia (914) correspondientes al ensanchador respectivo.

Abstract: Systems and methodologies are described that facilitate establishing a forward link acknowledgement channel and transmitting acknowledgment signals thereupon. In particular, the signals can be spread within contiguous channel clusters in a tile where the signals in the cluster are mutually orthogonal to one another. Additionally, the signals can be multiplexed over a plurality of frequency regions. In this regard, the acknowledgment signals are diverse with respect to frequency and interference; moreover, the signals can be received and decoded even where one of the channels experiences high interference. Furthermore, the acknowledgement signals can also communicate a channel deassignment value, which allows devices to utilize persistent channels in communicating data to one another

Abstract: Techniques for transmitting signaling with localized spreading are described. In one design, a transmitter (e.g., a base station) spreads multiple signaling symbols to obtain multiple sets of output symbols and further maps the multiple sets of output symbols to multiple time frequency blocks. The spreading may be localized to each time frequency block. Prior to the spreading, the transmitter may scale the multiple signaling symbols with multiple gains determined based on the transmit power for these signaling symbols. The transmitter may scramble the scaled signaling symbols to obtain scrambled symbols and may spread the scrambled symbols to obtain the multiple sets of output symbols. The transmitter may map each set of output symbols to a respective time frequency block.

Abstract: Se describen técnicas para transmitir señalización con dispersión localizada. En un diseño, un transmisor (por ejemplo, una estación base) dispersa e múltiples símbolos de señalización para obtener múltiples conjuntos de símbolos de salida y mapea además los múltiples conjuntos de símbolos de salida en múltiples bloques de frecuencia tiempo. La dispersión puede localizarse en cada bloque de frecuencia tiempo. Antes de la dispersión, el transmisor puede escalar los múltiples símbolos de señalización con múltiples ganancias determinadas con base en la potencia de transmisión para estos símbolos de señalización. El transmisor puede encriptar los símbolos de señalización escalados para obtener símbolos encriptados y puede dispersar los símbolos encriptados para obtener los múltiples conjuntos de símbolos de salida. El transmisor puede mapear cada conjunto de símbolos de salida en un bloque de frecuencia tiempo respectivo.
