    Abstract: In the method of making downlink operational measurements a measurement request from one of a main controller and a first base station is sent to at least a second base station. The measurement request requests the second base station to instruct mobile terminals in communication therewith to make operation measurements of at least one signal transmitted by the first base station. The second base station transmits a measurement instruction to the mobile terminals in communication therewith in response to the measurement request. The measurement instruction instructs the mobile terminals in communication with the second base station to make operational measurements of the signal transmitted from the first base station. Then the second base station receives results of the operational measurements from the mobile terminals in communication therewith. Alternatively or in addition, the second base station makes the operational measurements.

    Abstract: A wireless telecommunications system base station architecture is disclosed that supports receive diversity, sectorization, and radio pooling without the need for a sniffer radio or a switching matrix between the radios and the receive antennas. An illustrative embodiment of the present invention comprises: a first receive antenna (606) for receiving a first incoming signal; a second receive antenna (606) for receiving a second incoming signal; a first transmit antenna (606) for transmitting into a first sector; a second transmit antenna (606) for transmitting into a second sector; a first switch (607) for receiving a first outgoing signal and a first control signal, and for routing the first outgoing signal to at least one of the first transmit antenna and the second transmit antenna based on the first control signal; and a first radio (601) for receiving the first incoming signal from the first receive antenna and the second incoming signal from the second receive antenna, and for providing the first outgoing signal and the first control signal to the first switch.

    Abstract: Apparatus for properly receiving communication signals having relatively high dynamic ranges and which are transmitted by equipment of a communication system includes a receiver comprising a plurality of filters (606,608,610) each of which represents a frequency band assigned a specific dynamic range. A controller (624) coupled to the receiver determines the amplitude of the received signals. The controller is also coupled to a call processing module (628). The controller also determines whether the received signal is in the proper frequency band; that is whether the amplitude of the received signal is within the assigned dynamic range of the frequency band within which the signal is transmitted. When the signal is not in the proper frequency band, the controller in conjunction with the call processing module transmits a message to the equipment that transmitted the received signal instructing the equipment as to which frequency band to transmit the signal.

    Abstract: High speed data transfer from a base station to a mobile terminal is provided using an additional wide band communication channel that supplements the communications provided by the reverse (mobile to base station) and forward (base station to mobile) links used in cellular or PCS communications systems. In one embodiment, the standard forward and reverse links are used as control channels for data transfers over the additional or adjunct forward wide band channel. In another embodiment, the communications carried out over the narrow band forward link channel are sent over the adjunct wide band forward channel thereby eliminating the need for a narrow band forward link channel.

    Abstract: In a mobile communication system, independent versions of a signal are transmitted over plural antennas. The antennas are either spatially separated or orthogonally polarized with respect to each other so that the independent versions of the signal are not subjected to correlated fading. Each independent version of the signal is transmitted from a respective antenna a fixed delay after transmission of a previous version of a signal from a different antenna. The fixed delay is at least one information bit of the signal. Received versions of the signal are equalized in an equalizer or RAKE architecture to provide a composite signal. The equalizer has respective sets of equalizer taps that are separated from adjacent sets of equalizer taps by the fixed delay. The RAKE architecture has respective sets of RAKE forgers that are separated from adjacent sets of RAKE fingers by the fixed delay.
