    Abstract: In a reverse link of a wireless CDMA communication system, a method of maintaining an idling mode connection between a field unit and a base transceiver station is provided using various techniques to maintain the idle mode connection at a reduced power level. A preferred embodiment computes a time slot or frame offset based on modulo function using a field unit identifier in order to distribute field unit maintenance transmissions among available slots or offsets. An alternate embodiment detects explicit signaling states changes at the physical layer and causes power target changes. A further embodiment transmits maintenance data during predetermined time intervals, coordinated between the field units and BTS, allowing power levels to be adjusted accordingly.

    Abstract: A wireless repeater employing echo cancellation uses a non-linear element in digital baseband to compress the digital transmit signal waveform, thereby allowing distortions in the transmitter circuit as well as interference to be cancelled. In one embodiment, the repeater applies non-linear baseband compression to the digital transmit signal in the digital domain to reduce the peak-to-average amplitude of the digital transmit signal prior to digital-to-analog conversion and prior to over-the-air transmission and prior to sampling of the digital transmit signal for use as the reference signal for echo cancellation. The intentionally introduced non-linear distortion in the transmit signal improves echo cancellation and stability of the repeater. In one embodiment, the non-linear compression is applied only when the digital transmit signal is at or exceed a given power level or a given gain level.

    Abstract: A base station receives a reverse link signal from a given field unit that includes a common code (i.e., shared by other field units) and a unique orthogonal code (i.e., distinguishing the given field unit from other field units). The reverse link signal travels in a multi-path environment along a primary path and at least one secondary path. The base station makes a diversity decision based on the unique orthogonal code seen at two different phases. The base station determines a gross timing offset to align the common code of the given field unit with the common code from other field units using unique orthogonal codes. The given field unit makes a corresponding coarse adjustment of the phase of its common code.

    Abstract: A method of managing the number of base station engaged in soft hand-off in a mobile communication system. The method involves manipulating a subscriber based directional antenna so as to control the number of base transceiver stations, pilot channels, beacon signals or other signals detected to be used in soft hand-off processing. The adaptive antennas are modified to manage the number of active set members, such as by manipulating direction, beamwidth, or other antenna parameters.

    Abstract: An improved arrangement is described for signaling enhanced capabilities of a wireless data communication system to a dual-mode wireless handset seeking access to such capabilities and normally operating in a first (non-enhanced) mode. The arrangement, which is especially advantageous for ascertaining operating mode capabilities of a new cellsite to which the handset is being handed off from an existing cellsite, includes a separate capabilities server that is associated with the system and contains a data base populated with information indicative of such capabilities. The handset generates a suitable query message which is transmitted to the data base in the first mode after the handoff to retrieve the capability information for the new cellsite location. The handset is switched from the first mode to the second (enhanced) mode for post-handoff operation if the retrieved capability information indicates that the new cellsite is capable of operation in the enhanced mode.

    Abstract: A repeater environment is provided operative to deploy a feedback cancellation loop that is adaptively coupled with an antenna array such that a selected metric can be derived by deploying a selected filter bank operative to process the signal on a bin by bin basis and the derived metric can be applied to the antenna array and feedback cancellation loop combination to improve signal integrity and amplification. In an illustrative implementation, an exemplary repeater environment comprises, a transmitter, a receiver, an equalized feedback cancellation loop circuitry comprising a filter bank, the cancellation loop being operatively coupled to an antenna array. In the illustrative implementation, the feedback cancellation loop can receive signals as input from a cooperating antenna array and provide output signals such as a feedback leakage signal to a cooperating antenna array.
