Abstract: A narrowband interference cancellation system, method and digital signal processor is disclosed that removes narrowband interference in wide band communication systems. The system includes a narrowband processing component, wideband processing component, soft metric generator and at least one filter. The system is configured to receive a signal, identify one or more narrowband interferers in the received signal and filter out identified narrowband interferers. The narrowband processing component includes a filter bank configured to separate the received signal into a predetermined number of channel bands and identify a band with interference. The wide band processing component provides an average level for an unfiltered version of the received signal. The soft decision metric generator produces metrics based on predetermined thresholds. The filters receive coefficients that are determined using outputs from the soft decision metric generator that are first averaged using long term integrators and then stored in lookup tables.

Abstract: An apparatus, architecture and method for floor control in a Push-to-Talk system. A mobile station (203) may transmit a floor request message or messages and request multiple floors. Each floor may correspond to a media type having multiple media streams. A PoC server (201) assigns a priority to media types and/or media streams such that for example, a mobile station (203) may have a floor to transmit a video clip having audio and video streams to a talk group (207), and a member of the talk group may have a floor to transmit audio voice commentary on the media to the talk group (207). The embodiments of the present invention enable multimedia communication use cases without the need for duplication of the state machine at each node, thereby conserving resources.

Abstract: A method (600) performed by a packet scheduler of an access point (215) of adaptively resizing a scheduling window in a Quality of Service enabled Local Area Network (200) is disclosed. The packet scheduler schedules data packets for a given duration, termed a scheduling window. The packet scheduler according to an embodiment of the invention adaptively changes the duration of the scheduling window based on the QoS requirements of data packets to be transmitted to and from the access point (215). In particular, the duration of the scheduling window is changed based on the delay requirement of the data packet having the most constraint QoS requirement.

Abstract: A communication device and method for controlling reverse link transmissions. The device receives a broadcast transmission signal and determines a quality level of the broadcast transmission signal. It then communicates with the base station to establish how frequently reverse link transmissions will occur depending on the determined quality level. Alternatively, a network element can determining when a parameter crosses a threshold and transmit a message to select wireless communication devices to start gating on a reverse link when the parameter crosses the threshold.

Abstract: A method and apparatus for mitigating the impact of lost data due to cell reselection for mobile stations operating in packet data transfer mode is described. A mobile station may perform cell reselection 2 to 4 times per minute when located in an urban area, even if the mobile station remains stationary. A mobile station moving through a communications network (100) may cross over various cell and routing area boundaries. Further, a mobile station operating in push-to-talk mode may lose up to 8 seconds of data when reselecting a cell in a new routing area. A serving cell transmits an information element (301, 303, 305) in which the mobile station is informed whether cells in its neighbor list are in the same routing area as its serving cell. If the radio link to the serving cell is acceptable then the mobile station avoids reselection to cells outside its serving cell routing area.
