Abstract: A resource is assigned to each of a plurality of distributed, independent hardware resources in a base station, the resource comprising a sequence of radio frequency resources that follow a hopping sequence. Hardware resources are identified that are available to transmit a page via their respective assigned first resource. One of the identified available hardware resources from which to transmit the page is selected to transmit the page via the resource to which the selected hardware resource is assigned. The page is received at a user terminal via the resource; and a page response is transmitted via another resource to the selected hardware resource in response to the page.

Abstract: A method and apparatus for mitigating co-channel and inter-channel interference in an antenna array system. According to one aspect, the channel-select filter of a base station or other communication device is modified to detect inter-channel interference on at least one non-primary channel when the transmitter is communicating with a remote user terminal on a primary channel. The spatial characteristic of the interference is determined and used to obtain a weight that mitigates the inter-channel interference. According to another aspect, the spatial characteristic of co-channel and/or inter-channel ghost signal interference caused by a transmitter is determined and used to mitigate the effects of such interference.

Abstract: In one embodiment of the present invention, a receiver can only properly receive signals that were intended for the receiver because the data descrambling (230) depends on the identity of the receiver. In one embodiment, the invention is a communication device including a data source (202) containing data to be transmitted to a remote radio, and a randomizer (206) to scramble the data using an identifier related to the remote radio. In one embodiment, at least a part of the identifier related to the remote radio is used as a least part of a seed of the randomizer (206).

Abstract: A data stream is transmitted between a base station and user terminal. A first resource that is available to transmit a page is selected at the base station and the page transmitted from the base station via the first resource. The page is received at the user terminal via the first resource and a second resource that is available to transmit a page response is selected at the user terminal. A page response is transmitted from the user terminal via the second resource in response to the page. A data stream is then transmitted between the base station and user terminal via a third resource. In one embodiment, the first, second and third resources utilize the same sequence of radio frequency resources that follow a hopping sequence among a set of available radio frequency resources. In one embodiment, at least two of the first, second and third resources utilize the same sequence of radio frequency resources. In yet another embodiment, the resources utilize different sequences of radio frequency resources.

Abstract: A method, communication device, and machine-readable medium. The method includes sending a first poll from a first base station having a smart antenna system to a first user terminal. The first base station receives a first uplink response signal from the first user terminal as a result of the first user terminal successfully receiving the first poll. The first base station also receives at least one other uplink response signals as a result of at least one other remote user terminal successfully receiving a second poll from a second base station. The first base station transmits downlink data to the first user terminal using a downlink smart antenna processing strategy for transmitting to the first user terminal, including mitigating interference to the first and one or more other remote communication devices from which the first base station received a first or other uplink response signal and that may be receiving during transmission of downlink data to the first user terminal. The downlink smart antenna processing strategy is using the first and other received uplink response signals. The first base station uses a first protocol with its associated user terminals and the second base stations uses a second protocol that is coordinated with the first protocol to enable the first base station to receive the first and other uplink response signals from second and one or more other remote communication devices that may be receiving during the step of transmitting downlink data to the first user terminal.
