Abstract: An improved method and system for performing a pilot signal searching operation in anticipation of handoff in mobile station (18) communication between base stations (12, 14). The mobile station (18) maintains a list of Active Set pilot signals transmitted from base stations with which the mobile station is to communicate through, and a list of Neighbor Set pilot signals (N) from base stations within a predetermined proximity of the mobile station (18). The searching operation contemplates comparing pilot signal strength measurements corresponding to each base station entry within the Neighbor Set (N) to a first predetermined level. One or more entries from the Neighbor Set (N) having a base station signal strength measurement greater than the first predetermined level may be placed in the Pre-Candidate Set (PC). The strength of the pilot signals associated with entries in the Pre-Candidate Set (PC) are then further evaluated to determine eligibility within the Candidate Set (C), from which are selected the entries comprising the Active Set.

Abstract: The power control process of the present invention enables a base station communicating over a forward packet channel to a mobile radio to control the power of the mobile radio transmitting over a reverse packet channel to the base station. The base station maintains a maximum energy per bit to total interference spectral density ratio threshold for the reverse channel as well as a desired threshold that results in a low frame error rate. By comparing each radiotelephone's estimated energy per bit to total interference spectral density ratio to the desired and maximum thresholds, power control commands to increase or decrease the radiotelephone's transmit power are generated depending on the outcome of the comparison.

Abstract: A method and apparatus for simulating signal interference within a communication system, such wireless or cellular communication systems. The communication system is preferably of a type in which code division multiple access (CDMA) spread spectrum communication signals are used. The method for simulating signal interference power received by a base station receiver includes estimating a first composite signal power (100, 110) corresponding to the sum of signal power transmitted by a first set of simulated users located in a first cell. An estimate is also made of a first normalized data rate (410) for transmission of the composite signal. A first interference signal is then generated (114, 126, 128, 130) at a power level determined on the basis of the first composite signal power and normalized data rate. In a preferred implementation, the first interference signal power is adjusted in accordance with an average power fluctuation (420) arising as a consequence of closed loop power control (715). Further, a second composite signal power is determined by estimating the sum of signal power transmitted by a second set of simulated users located outside of the first cell. A similar estimate is made of a second normalized data rate at which this signal power is transmitted by the second set of simulated users. This allows the generation of a second interference signal based on the second composite signal power and normalized data rate. Generation of the first interference signal will typically involve synthesis of electrical noise (160) over a predetermined frequency band. The power of the electrical nois is then adjusted (170) in accordance with the product of the first composite signal power and the first normalized data rate. Furthermore, a random variable sequence may be used (400, 460, 530) to model variations in the first composite signal power.

Abstract: A novel and improved apparatus for encoding a signal which is bursty in nature. In a code excited linear prediction algorithm, short term redundancies are removed by formant synthesis filter (6) and long term redundancies are removed by pitch synthesis filter (4) from digitally sampled speech, and the residual signal which is bursty in nature must be encoded. The residual signal is encoded using three parameters a burst shape index corresponding to a burst shape provided by burst element (10), a burst gain which scales the burst shape through scalar multiplication in multiplier (14), and a burst location value which determines the temporal location of the scaled burst in variable delay element (16). Together the three parameters specify a waveform to match the residual signal. Further disclosed is a closed loop exhaustive search method by which to find the best match to the residual waveform and a partially open loop method wherein the burst location is determined by an open loop analysis of the residual waveform, and the burst shape and gain parameters are determined in a closed loop fashion. The matching operations are performed by minimizing the mean squared error (MSE) using summing element (18), energy computation element (20) and minimization element (22).

Abstract: The process of the present invention enables a communication link to have a higher data rate input signal while maintaining a constant data rate output signal. The method first convolutionally encodes the input data signal to produce a plurality of convolutionally encoded signals. Each of the convolutionally encoded signals are comprised of a plurality of data symbols. Each data symbol is repeated a predetermined number of times to produce a code repetition data sequence at a predetermined and fixed rate. The data sequence is then punctured such that symbols in predetermined locations of the data sequence are deleted thus generating a data sequence at a predetermined and fixed rate which is lower than that of the original data sequence. The encoded signals with the repeated data symbols are multiplexed to produce a data sequence.

Abstract: A method of invoking and cancelling voice and data service between a mobile unit and a base station. Using a standard telephone system, the connection for a voice service and a data service is the same. With the introduction of the digital wireless link, the voice connection and the data connection are different. Therefore new dialing commands which indicate the intent of the connection are created. These commands can also be used to designate the intent of the call from a mobile unit capable of data and voice service but not capable of simultaneous voice and data service. They can also be used to invoke simultaneous voice and data services.
