    Abstract: A method and apparatus for mitigating effects of multipath fading, interference, and noise in a single sideband (SSB) signal transmitted by a radio communication system and demodulated by a portable subscriber unit (122) utilizing a demodulator (304) compensated by a pilot signal power (406). The apparatus performs the mitigation process by calculating (708) a pilot fading threshold in addition to a muting threshold. When samples of the mean pilot signal power fall below the fading threshold, the compensation of the demodulated signal is adjusted (714). In addition, when the mean analog message signal power falls below the muting threshold, the samples included in the predetermined portion of the message are muted (718).

    Abstract: A method and apparatus is used for transmitting an outbound message in a two-way messaging system having a plurality of cells employing frequency reuse. The outbound message is transmitted to a selective call transceiver (122) utilizing a first frequency reuse plan (312). The two-way messaging system awaits a positive acknowledgment (316, 318) from the selective call transceiver (122) confirming that the outbound message was received with an acceptable quality. The two-way messaging system retransmits the outbound message to the selective call transceiver (122) utilizing a second frequency reuse plan (332), in response to receiving a negative acknowledgment and also in response to failing to receive any acknowledgment within a predetermined time after transmitting the outbound message.

    Abstract: Grâce à la méthode et à l'appareil décrits, une unité de communication (10) transmet une demande de voie de communication et l'installation de base (12) la plus proche procède à l'attribution ou à l'affectation de la voie de communication. Une installation de base reçoit le signal de demande de voie, mesure le niveau d'intensité du signal reçu, et si ce niveau dépasse un certain seuil, une voie de communication est affectée à l'unité de communication demandeuse, ce qui crée une liaison de communication. Si l'intensité du signal de demande de voie ne dépasse pas le seuil fixé, l'installation de base retarde l'attribution d'une voie de communication pendant une durée inversement proportionnelle au niveau d'intensité du signal mesuré afin de permettre à d'autres installations de base d'attribuer une voie de communication à l'unité de communication demandeuse. Si l'installation de base constate qu'une autre installation de base a attribué une voie de communication à l'unité de communication demandeuse, le processus d'affectation est interrompu, et l'installation de base continue à rechercher des signaux de demande de voie.

    Abstract: A communication system is designed that reduces co-channel interference when heterogeneous users are sharing spectrum. The system design enables a plurality of pairs of users to communicate their channel utilization time periods by using the durations and start or stop times of certain transmissions to signal the start times and durations of later transmissions. Other system users using possibly different communications protocols and different modulation technologies can measure the durations of received transmissions and to infer channel usage based on these durations.

    Abstract: A non-real time messaging system (200) for targeting messages to a subscriber unit (222) comprises a synchronized profile of where a subscriber unit should be located (a predetermined base transmission area for transmission of messages to the subscriber unit) maintained between a controller (212) and the subscriber unit. The subscriber unit detects when the subscriber unit is not within the receiving range of a predetermined base transmission area, informs the controller and the controller directs subsequent transmissions to an area identified by the subscriber unit and otherwise transmits subsequent messages to the predetermined base transmission area. The system further includes a plurality of base receivers (217) coupled to the controller for receiving transmissions from the subscriber units and allowing the controller to detect when the subscriber unit is not within the receiving range of a predetermined base transmission area.
