    Abstract: A method and apparatus providing softer handoff of a mobile unit (90) between sectors (50, 70, and 80) of a common base station (60). A sectorized base station (60) comprises a set of demodulation elements (240A - 204N). Each demodulation element (240A - 204N) may be assigned to a signal from one of a plurality of sectors. The output of the demodulators (240A - 204N) are combined before the decoding process independent of the sector from which the data originated. This configuration provides improved output data reliability, more stable power control, and more efficient use of resources at the base station.

    Abstract: A method for providing power control with variable data rate, the method comprising: receiving a data frame having an input data rate selected from a plurality of possible input data rates; selecting an encoding rate based on the input data rate; encoding data frames to produce output symbols, repeating output symbols using first and second generating polynomials and multiplexing the repeated output symbols, selecting a puncturing format to puncture data bits and producing output data having a constant output data rate for a number of possible input data rates based on a combination of input data rates, selected encoding rate and selected puncturing format for providing said variable data rate communication link; determining a frame error rate for a number of possible input data rates; calculating differences between the frame error rates and a target error rate and adjusting the power depending on whether the difference is greater, equal or less than a predetermined threshold.
