Abstract: A repeater for re-transmitting an incoming RF signal comprising: a first antenna array for receiving the incoming RF signal; a second antenna array for transmitting an outgoing RF signal; and a transceiver for down-converting the incoming RF signal to a down-converted signal, processing the down-converted signal, and up-converting the processed signal to produce the outgoing RF signal. The first antenna array is cross-polarized with respect to the second antenna array. The repeater also comprises an echo processor for attenuating in the down-converted signal an echo signal associated with the outgoing RF signal. The echo processor delays transmission of the outgoing RF signal in order to minimize the echo signal.

Abstract: A small office/home office base transceiver station (SOHO BTS) server capable of managing interference by correlating pilot strength measurements sent by mobile devices and directing the attenuation settings for each transmit path. An array of antennas coupled to an array of transmit paths are selectively activated one at a time. When a transmit path is activated, the SOHO BTS server sets the associated variable attenuator to its maximum level. The SOHO BTS server detects whether a radio environment report or and a pilot strength measurement message (PSMM) containing information about a mobile station's pilot strength is present. When the pilot strength is greater than a predetermined value, the SOHO BTS server increases the setting on the attenuator. Otherwise, the SOHO BTS server decreases the attenuator setting until such pilot strength information is available or if the lowest attenuator setting has been set. The other transmit paths are also tested accordingly.

Abstract: Beamforming techniques to limit radiated power where there is the potential for interference with macro-cellular coverage or with adjacent mobile stations. Smart antenna beamforming techniques (including the use of angle of arrival information) are combined with access probe information to determine the direction for radiated power and the level of the needed transmitted power as well for the small office or home (SOHO) environment. The placement of RF power in the SOHO specific to where it is needed, minimizes radiating power in directions where it will cause interference with macrocell coverage. In addition, the beamforming techniques provide a base transceiver station with an economical method to quickly solve coverage issues internal to a SOHO, without introducing interference external to this coverage environment. In addition, there specific placement of the RF power where it is needed provides an increase in spectral efficiency of a deployed network.

Abstract: A system and method is disclosed for improving downlink performance of an adaptive antenna array in a vehicular environment. The system comprises a mobile station that has a first mobile antenna and a second mobile antenna. A spatial signature estimator associated with a base transceiver station obtains spatial signatures from signals from the first mobile antenna and from the second mobile antenna within an uplink interval. Correlation circuitry uses the spatial signatures to identify a least changing spatial signature to obtain an optimal downlink beamforming weight vector to be used in the transmission of a signal to the mobile station in the next downlink interval.
