Abstract: A novel and improved method for performing transmit power control is described. A signal is transmitted at a transmit power and includes a traffic channel transmitted at a traffic channel transmit power, and a pilot channel transmitting at a pilot channel transmit power. The receive energy of the pilot channel is measured, and compared with a threshold. A power control command is generated and transmitted to the system generating the signal. This determines whether the command is to be applied to either the traffic channel, the pilot channel, or the entire signal. The power of the determined channel(s) is adjusted accordingly.

Abstract: In a communication system capable of variable rate transmission, scheduling of high speed data transmission improves utilization of the forward link and decreases the transmission delay in data communication. Each remote station is assigned one primary code channel for the duration of the communication with a cell. Secondary code channels of various types and transmission capabilities can be assigned by a channel scheduler for scheduled transmission of data traffic at high rates. Secondary code channels are assigned in accordance with a set of system goals, a list of parameters, and collected information on the status of the communication network. Secondary code channels can be grouped into sets of secondary code channels. Data is partitioned in data frames and transmitted over the primary and secondary code channels which have been assigned to the scheduled user.

Abstract: A method and apparatus for controlling transmission power in a mobile communication system is disclosed. The method disclosed provides for a closed-loop power control method. A characteristic of a propagation path between a first communication station and a second communication station is determined and a power control step size selected accordingly. Closed loop power control commands are received at the first communication station and its transmission energy is adjusted in accordance with the closed loop power control commands and the power control step size.

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 for time synchronizing a slave base station 62 with a reference base station 64. The slave base station attains synchronization with the reference base station through messages transmitted from and received by a mobile station 60 in the soft handoff region between the reference base station and the slave base station. First, the round trip delay between the mobile station and the reference base station is measured by the reference base station. Once the mobile station acquires the signal from the slave base station, it measures and reports the difference between the amount of time it takes a signal to travel from the reference base station to it and the amount of time it takes a signal to travel from the slave base station to it. The last measurement necessary is a measurement by the slave base station of the time difference between the time it received the reverse link signal from the mobile and the time of transmission of a forward link signal from the base station.

Abstract: In the present invention, the slave base station (64) attains synchronization with reference base station (62) through messages (50) transmitted from and received by a mobile station (60) either in the soft handoff region between the reference base station (62) and the slave base station (64) or within a range which allows the mobile station (80) to communicate with the slave base station (64).When the mobile station (62) is not in communication with both the reference base station and the slave base station (62), the n the round trip delay between the mobile station and the reference base station is measured by the reference base station (62). The reference base station (62) communicates the PN code used by the mobile station over the reverse link to the slave base station. The slave base station (64) acquires the signal (504) from the mobile station (60) and determines when the signal from the mobile station arrives. The slave base station (64) then makes and estimates as to the length of the delay between transmission of a signal from the mobile station (60) to the slave base station (64). Based upon these measurements and estimates, the slave base station (64) determines the error which is present in the slave base station system time. 1 claim, 9 figures

Abstract: In a method for negotiating service configuration in a communication system having at least one dedicated channel which is not shared by communication devices in the communication system, a request message indicative of a proposed service configuration is generated in a service negotiator (20). The request message is multiplexed, in a multiplexer (22) coupled to the negotiator (20), with an information data signal to produce a multiplexed signal. The multiplexed signal is encoded in an encoder (24) interposed between the multiplexer (22) and a transmitter (26) in accordance with a service configuration selected by the service negotiator (20). The multiplexed and encoded signal is transmitted by the transmitter (26) over the dedicated channel. Received signals are decoded a decoder (16) interposed between a receiver (14) and a demultiplexer (18). A response message indicative of a response to the proposed service configuration is received by the receiver (14). A determination is made by the service negotiator (20) whether the response message is indicative of a mutually acceptable service configuration. The encoder (24) is directed by the service negotiator (20) to encode the information data signal in accordance with the proposed service configuration if the response message is indicative of an acceptable service configuration. The encoder (24) is directed by the service negotiator (20) to encode the information data signal with a universal default service configuration if the response message is not indicative of an acceptable service configuration.
