Abstract: A method and apparatus for efficient candidate frequency search while initiating a handoff in a code division multiple access communication system. The method includes when the pilot signal is transmitted by the mobile station that is power controlled to a target receive level, the traffic channel power level is increased relative to the pilot channel to improve receiver performance. An improved feature is that the received pilot received at the base station stays the same while the receiver receives extra energy in the redundant traffic symbols received to enhance the probability of correctly decoding the received frame. The base station detects the absence of the mobile station transmitted signal from the frequency of interest. If the base station is aware of the starting time and duration of the absence, it can focus its detection during this predetermined time period. The performance can be improved if the absence of the signal is spread across two frames at the frame boundary.

Abstract: A method and apparatus for performing inter-system hard handoff between communication systems or inter-frequency hard handoff within a CDMA communication system is disclosed. The purpose of this invention is to reduce the probability of dropped calls during inter-system hard handoff. In the event that a hard handoff attempt is unsuccessful, the mobile station will return to the original system with information which the communication system of the present invention uses to assist in the performance of future handoff attempts. Alternatively, with no handoff attempt made, the mobile station monitors the destination system then returns to the original system with information used to assist in subsequent handoff attempts. The information returned from monitoring a CDMA system consists of results of a search for one or more pilots given at offsets in a specific list provided to the mobile station by the base station or a set of offsets based upon a predetermined search algorithm.

Abstract: Systems and methods for controlling power in a wireless communication system having multiple reverse-link channels. One embodiment comprises adjusting power levels of a first set of channels and a corresponding pilot channel while maintaining a set traffic-to-pilot (T/P) ratio between them, and adjusting T/P ratios for one or more remaining channels independently of the power level of the pilot channel. A base station determines whether frames received on the first set of channels contain errors and sends messages to a mobile station to increment or decrement the power levels, respectively, if the frames do or do not contain errors. T/P ratios of the additional channels are adjusted by determining whether frames received on the additional channels contain errors, incrementing or decrementing the T/P ratios appropriately, and transmitting the T/P ratios to the mobile station, which controls the transmission parameters for the respective channels in accordance with the received T/P ratios.

Abstract: A method for power control in a wireless communication system. An initial transmission of a data frame in the reverse link is received, and a first energy level of the data frame is measured. An energy deficit in the first energy level is then measured if the first energy level is insufficient to correctly decode the data frame, so that when the data frame is retransmitted with a second energy level equal to a difference between the first energy level and the energy deficit, the data frame can be correctly decoded with combined energy of the first energy level and the second energy level.

Abstract: An encoder adds redundancy to a block of information bits to be transmitted via different stations in a communication system. The redundancy permits decoding of the received symbols from less than a complete encoded block of information. The symbols received from the different stations are combined before decoding. The present invention relates to broadcast or multicast communications, otherwise known as point-to-multipoint communications, in a wireline or a wireless communication system.
