摘要： A simplified method for frequency offset estimation in a TDMA cellular PCS environment using &pgr;/4-shifted DQPSK comprises the steps of multiplying a complex conjugate of a received complex-valued symbol and a succeeding symbol to produce a comparison vector having an angle equal to the phase angle between the received complex-valued symbol and the succeeding symbol, rotating the comparison vector so that the angle thereof is between 0° and 90°, and estimating the frequency offset by determining a constant deviation of the phase angle from an ideal phase angle value of 45° by calculating an average phase angle for a plurality of successive comparison vectors or correlating the rotated comparision vector against a bank of unit vectors to determine a maximum correlation.

摘要： An algorithm calculates a correction value to be applied to a slot in an adjustment period for power correction. For each slot, the algorithm determines whether adding a correction value in a given slot would bring the actual accumulative adjustment value closer or farther from a total desired power correction value for the adjustment period. In one embodiment, the correction value is added to consecutive slots in the adjustment period to conduct the correction as fast as possible. The algorithm also checks the total amount of adjustment applied to the slots over a sliding adjustment window within the adjustment period to make sure that the total amount of adjustment applied to the slots in the adjustment window do not exceed a predetermined maximum threshold.

摘要： A method of scaling soft symbols of an uplink E-DCH is provided, where the E-DCH is received from a user in a network for processing in a base station receiver in the network employing a log-MAP turbo decoding algorithm to process the E-DCH. The E-DCH includes an E-DPDCH from which the soft symbols are generated at the base station receiver, and an E-DPCCH used to transmit control information associated with the E-DPDCH, which along with configuration information from a radio network controller (RNC) of the network enables the base station receiver to determine a reference amplitude ratio linked to the actual power offset of the E-DPDCH from the legacy DPCCH. In the method, an estimated E-DPDCH to DPCCH amplitude ratio that represents a scaling factor for the soft symbols is determined, and the soft symbols are scaled by the scaling factor to enable the soft symbols to be processed by the log-MAP turbo decoding algorithm in the base station receiver.

摘要： An algorithm calculates a correction value to be applied to a slot in an adjustment period for power correction. For each slot, the algorithm determines whether adding a correction value in a given slot would bring the actual accumulative adjustment value closer or farther from an accumulative adjustment target value. The accumulative adjustment target value has a linear relationship with the slot number and is calculated for each slot to ensure that any corrections are evenly distributed over the adjustment period for a smooth correction. In one embodiment, the algorithm also checks the total amount of adjustment applied to the slots over a sliding adjustment window to make sure that the total amount of adjustment applied to the slots in the adjustment window do not exceed a predetermined maximum threshold.

摘要： A method of adjusting a power level of communications over a channel in a wireless communications network. In the method, a determination (e.g., by a radio network controller (RNC)) is made regarding a number of base stations actively communicating with a mobile station. For example, the determination may indicate whether the mobile station is engaged in soft handoff or simplex mode. One of a plurality of power control algorithms (e.g., a fixed offset power control algorithm, a channel quality indicator (CQI) power control algorithm, etc.) is selected based on the determination. A power level of communications over the channel (e.g., a downlink communications channel to the mobile station) is then adjusted in accordance with the selected power control algorithm.

摘要： In a method of controlling transmit power for a user call migrating between a first entity and a second entity in a base station of a wireless communication system, power control may be performed, as a call of the user is migrated from the first to the second entity, or vice versa, based on an adjustment ratio value. Parameters for balancing transmit power as the user call is migrated from the first entity to the second entity may be selected so that any difference in transmit power does not adversely affect system performance.
