Abstract: Briefly, in accordance with one embodiment, a method of transmitting signals is provided. Signal waveforms are transmitted from at least two respective sectors. The at least two respective sectors are from at least two different sets of a superset of sectors. The transmitted signal waveforms include signal waveforms at least nearly mutually orthogonal at least along a particular signal dimension. An advantage of such an embodiment, for example, is reduced signal interference.

Abstract: In a data communication system capable of variable rate transmission, high rate packet data transmission improves utilization of the forward link and decreases the transmission delay. Data transmission on the forward link is time multiplexed and the base station transmits at the highest data rate supported by the forward link at each time slot to one mobile station. The data rate is determined by the largest C/I measurement of the forward link signals as measured at the mobile station. Upon determination of a data packet received in error, the mobile station transmits a NACK message back to the base station. The NACK message results in retransmission of the data packet received in error. The data packets can be transmitted out of sequence by the use of sequence number to identify each data unit within the data packets.

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.
