Abstract: A method and apparatus for coordinating the time at which a mobile station (5) performs searches for alternative systems to which a hard handoff will occur. In one system which includes the present invention, the mobile station (5) receives a command which instructs the mobile station (5) as to when to tune to alternative frequencies in order to search for indications of the presence of an alternative system. In another system which includes the present invention, predetermined times are defined with respect to a reference point in time that is common to both an origination base station (10) and a mobile station (5). The mobile station (5) tunes to alternative frequencies to perform searches only during these predetermined times. In addition, the mobile station (5) coordinates the transmission of reports which indicate the results of searches for alternative systems such that these reports are only transmitted from the mobile station (5) when the mobile station (5) is tuned to the origination frequency.

Abstract: Apparatuses for a transmitter and a receiver which enhance the performance of a system utilizing interleaving and transmit diversity by reordering the sequence of symbols transmitted along the different transmission channels. This enhancement is accomplished by providing different shuffling functions in conjunction with the interleavers and deinterleavers used with different transmission channels, which decreases the probability of loss of sequential symbols when transmission channels or antennas become correlated.

Abstract: Techniques to adjust the setpoint of a power control loop in a wireless communication system. The setpoint may be adjusted based on frame status indicative of erased/good decoded frames, one or more (typically soft) metrics 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 include one of a re-encoded power metric and a modified Yamamoto metric. 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: 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.

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.
