    Abstract: A channel structure has at least two channel sets. Each channel set contains multiple channels and is associated with a specific mapping of the channels to the system resources available for data transmission. Each channel set may be defined based on a channel tree having a hierarchical structure. To achieve intra-cell interference diversity, the channel-to-resource mapping for each channel set is pseudo-random with respect to the mapping for each remaining channel set. In each scheduling interval, terminals are scheduled for transmission on the forward and/or reverse link. The scheduled terminals are assigned channels from the channel sets. Multiple terminals may use the same system resources and their overlapping transmissions may be separated in the spatial domain. For example, beamforming may be performed to send multiple overlapping transmissions on the forward link, and receiver spatial processing may be performed to separate out multiple overlapping transmissions received on the reverse link.

    Abstract: Systems and methods for controlling transmission power are provided. The systems and methods vary the power of a signal provided to a power amplifier based upon the location of a frequency or frequencies of signals to be transmitted within the transmission frequency band, the location of a hop region within the transmission frequency band, the bandwidth of signals to be transmitted, or combinations of these approaches.

    Abstract: Una estructura de canal tiene por lo menos dos conjuntos de canales; cada conjunto de canales consta de multiples canales y esta asociado con un mapeo especifico de los canales a los recursos del sistema disponibles para transmision de datos; cada conjunto de canales se puede definir con base en un arbol de canal que tiene una estructura jerarquica; para lograr la diversidad de interferencia intra-celula, el mapeo de canal-a-recurso para cada conjunto de canales es seudo-aleatorio con respecto al mapeo para cada conjunto de canales restante; en cada intervalo de programacion, las terminales son programadas para transmision en el enlace de avance y/o inverso; a las terminales programadas se les asignan canales de los conjuntos de canales; multiples terminales pueden utilizar los mismos recursos de sistema y sus transmisiones en traslape se pueden separar en el dominio espacial; por ejemplo, la formacion de haces se puede realizar para enviar multiples transmisiones en traslape en el enlace de avance, y el procesamiento espacial del receptor se puede ejecutar para separar multiples transmisiones en traslape recibidas en el enlace inverso.
