Abstract: An apparatus and method for identifying remote communications transmitted via a repeater from remote communications not transmitted via the repeater. The method comprises the steps of receiving a plurality of signal transmissions originating from a plurality of remote stations, wherein each of the signal transmissions is associated with a call originating from one of the plurality of remote stations; processing the plurality of received signal transmissions to identify received transmissions that include a discriminant applied by a repeater; and designating each of the plurality of received signal transmissions as being transmitted via the repeater if the received signal transmission includes the discriminant.

Abstract: Apparatus and methods are disclosed for determining a tolerable propagation delay between a repeater and a base station in a communication system. In on e embodiment, a tolerable length of fiber optic cable between a repeater and a base station is determined. More particularly, a desired search window size in time is determined. A maximum fiber optic cable delay value is determined based on the desired search window size. Also, a ratio value of fiber optic cable delay value to fiber optic cable length is then determined. The tolerable length of the fiber optic cable is then determined based on the maximum fiber optic cable delay value and the ratio value.

Abstract: A method and apparatus are disclosed for setting total reverse link gain between a repeater and a base station. The method and apparatus generally comprise setting total reverse link gain between a repeater and a base station comprises determining an operating point for the repeater; establishing a reverse communication link between the base station and a transceiver device within a coverage area of the repeater; determining if an increase in a reverse link gain is substantially equal to an increase in a noise figure of the base station, using a transmit power of the transceiver device; and adjusting the reverse link gain by an amount based on the operating point and based on a difference in reverse link gain values, if the increase in the reverse link gain is substantially equal to the increase in the noise figure of the base station, to set the total reverse link gain.

Abstract: A method and apparatus for providing handoff between two communication systems. The systems can be CDMA systems operating at different frequencies or systems employing different technologies. In the first system, a base station (4) is configured to provide communications to two or more sectors, with at least one sector assigned to a corresponding repeater (8) which provides coverage overlapping that of both systems. As the remote station (6) moves into the coverage area of the repeater (8), the pilot signal of the repeater (8) is identified, measured and sent to the first system. If the measured pilot signal is above a predetermined add threshold, the repeater (8) is added to the active set of the remote station. The first system can handoff the remote station (6) to the second system: (1) upon initiation of a soft handoff by the base station of the first system; (2) if the pilot signal strength of the repeater (8), as measured by the remote station (6), exceeds a predetermined handoff threshold; (3) if the base station (4) of the first system is dropped from the active set of the remote station (6); (4) if the repeater of the first system is dropped from the active set of the remote station (6); or (5) if the base station (4) and repeater (8) of the first system are dropped from the active set of the remote station (6).

Abstract: Communications between a mobile and first and second base stations in a cellular system are directed by measuring the round trip delay of an active communication signal between the first base station and the mobile and entering a measurement directed hard handoff state by an active communication control unit located in a first mobile switching center of the system. The active communication control unit accesses a measurement directed hard handoff table to determine, on the basis of the measured round trip delay corresponding to the first active communication signal, whether the location of the mobile corresponds to an area where handoff is desirable, that is handoff will most likely not drop the communication in progress.

Abstract: The present invention is a novel and improved method and apparatus for transmitting and receiving code division multiple access (CDMA) signals. In a described embodiment of the invention, the radio frequency (RF) signals are received through a first polarization RF unit and a second polarization RF unit generating right slant samples and left slant samples. The right slant samples and the left slant samples are each searched and multipath processed independently and the resulting sets of soft decision data combined and decoded. In a preferred embodiment of the invention, right slant and left slant instances of the signal are generated and transmitted to increase the likelihood of differently polarized instances of the signal being available at the receive system.
