Abstract: Method and apparatus for congestion control in a wireless communication system. In one embodiment, the status of a congestion bit indicates the type of adjustment, such as increase or decrease, to be performed at an access terminal to determine the next data rate for transmissions on the reverse link. The status of the congestion bit is determined by comparing a congestion parameter to a predetermined threshold (186). One embodiment implements an outerloop threshold having a margin with respect to the desired congestion metric threshold. The outerloopthreshold is adjusted in response to comparing a measured congestion metric to the desired threshold (192, 194, 196). The outerloop threshold adjustment maintains the congestion metric to within a predetermined probability of exceeding the desired threshold.

Abstract: An expander for radially expanding a tubular element by axial movement of the expander through the tubular element is provided. The expander comprising an expander member having a front part of a first cross-sectional size; a rear part of a second cross-sectional size larger than the first cross-sectional size; and an intermediate part arranged between said front part; and, rear part and having a cross-sectional size varying between said first and second cross-sectional sizes. The expander member is provided with fluid supply means for supplying pressurized fluid to the inner surface of the tubular element at a location opposite the intermediate part when the expander member is arranged in the tubular element.

Abstract: A method and corresponding apparatus separately estimates signal amplitude and noise in received signals, particularly symbols encoded using turbo codes. The method and apparatus, however, may be applied to such estimation in power control wireless systems (CDMA systems), other concatenated coding schemes, etc. A method and apparatus initially estimate the signal and noise, separately, in the received signal, such as by using curve fitting techniques. Thereafter, a finer estimate is provided by using the amplitude of received pilot symbols or using an estimate of the noise from the received pilot symbols.

Abstract: Techniques to adjust the setpoint of a power control loop in a wireless communicaton system. The setpoint may be adjusted based on frame status indicative of erased/good decoded frames, one or more (typically soft) metri cs indicative of the confidence in the decoded results, power surplus/deficit indicative of the difference between the received signal quality and the setpoint and a threshold Eb/Nt needed for the desired level of performance, or a combination thereof. The metrics may include re-encoded symbol error rate, re-encoded power metric, modified Yamamoto metric, minimum or average LLR among decoded bits, number of decoding iterations, and possibly others, The setpoint may be adjusted in different manners and/or by different amounts depending on the above-noted factors. The techniques may be employed for forward and/or reverse links in CDMA systems.

Abstract: A power control system for controlling the transmission power in a system wherein the transmission power may be gated or capped. The receiver employs a combination of closed loop and outer loop power control. The outer loop is frozen upon detection by the receiver that the signal has been capped or gated.

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: Method and apparatus for controlling transmission power in a closed loop power control system, wherein power control commands are based on the energy of the previous power control commands. In one embodiment, the method compares changes in the received energy of received power control commands against expected changes in those commands based on previously transmitted power control commands, and identifies suspicious responses to said previously transmitted power control commands. Hypothesis testing of the received power control commands is performed accordance any identified suspicious responses.
