    Abstract: A method of controlling a load at a wireless communication base station includes determining an indication of a maximum path loss between the base station and any high speed data users currently in a cell served by the base station. A target loading limit for the cell is set based upon the determined indication of the maximum path loss. In disclosed examples, the indication of the maximum path loss corresponds to a distance between a high speed user and a base station. Another factor considered in disclosed examples includes the data rate of such a high speed user.

    Abstract: In one embodiment of the instant invention, a non-coherent transmission method for uplink control signals is provided. The transmission methodology uses a constant amplitude zero-autocorrelation (CAZAC) sequence for relatively short control signal lengths. The methodology includes creating a CAZAC sequence, truncating the CAZAC sequence into a plurality of segments; and transmitting each of the segments within a predetermined window of time.
