Abstract: A method and apparatus for providing an improved soft handoff algorithm in a wireless communication system for third generation code division multiple access ("CDMA") systems. The method comprises establishing communication between the wireless communication device and the at least one serving base station, the at least one serving base station having a list of at least one neighboring base station which neighbors the respective serving base station, monitoring the reverse channel signal strength at the wireless communication device from at least one neighboring base station, transmitting to a base station controller the wireless communication device signal strength detected at each neighboring base station, compiling at the base station controller a list of effective neighboring base stations from the at least one neighboring base station based on the monitored wireless communication device signal strength, transmitting the list of effective neighboring base stations to each at least one serving base station, periodically transmitting a neighboring base station list update message to the wireless communication device, the neighboring base station list update message including the effective neighboring base station list, storing the effective neighboring base station list as a neighbor set in the wireless communication device, performing forward channel signal strength searching of the neighbor set in the wireless communication device after storing the effective neighbor list as the neighbor set, and monitoring the signals from the effective neighboring base stations to accomplish a handoff between the at least one service base station and the receiving neighboring base station.

Abstract: In a code division multiple access communication system (100), a method and accompanying apparatus provide for controlling gain of a forward supplemental channel (482) by determining gain level of a forward fundamental channel (481) associated with supplemental channel (482) for being targeted for a common mobile station, determining an adaptive margin (Ma) for fundamental channel (481) and determining a forward supplemental channel gain (Gsch) based on the gain of supplemental channel (482) and the Ma. The Gsch may be successively decreased for subsequent data frames targeted for the common mobile station on supplemental channel (482) by successively decreasing the Ma until receiving a supplemental channel frame erasure indicator from the common mobile station. The Gsch may be increased for a subsequent data frame targeted for the common mobile station on supplemental channel (482) by increasing the Ma after receiving the supplemental channel frame erasure indicator from the common mobile station.

Abstract: A multi-carrier receiver capable of receiving one or multiple frequency channels simultaneously is described. In one design, the multi-carrier receiver includes a single radio frequency (RF) receive chain, an analog-to-digital converter (ADC), and at least one processor. The RF receive chain processes a received RF signal and provides an analog baseband signal comprising multiple signals on multiple frequency channels. The ADC digitizes the analog baseband signal. The processor(s) digitally processes the samples from the ADC to obtain an input sample stream. This digital processing may include digital filtering, DC offset cancellation, I/Q mismatch compensation, coarse scaling, etc. The processor(s) digitally downconverts the input sample stream for each frequency channel to obtain a downconverted sample stream for that frequency channel. The processor(s) then digitally processes each downconverted sample stream to obtain a corresponding output sample stream. This digital processing may include digital filtering, downsampling, equalization filtering, upsampling, sample rate conversion, fine scaling, etc.
