Latest Patents
One of his latest patents is titled "Method and apparatus for providing power control for CDMA dispatch services." This invention addresses the need for power control among listening participants in CDMA dispatch services. The concept involves 'shared channel signaling windows' for shared traffic channels. In this embodiment, the beginning of a signaling window is announced on the traffic channel, allowing remote units with the highest frame error rates to compute the shortest transmit delays. During this window, remote units transmit their power control signaling according to their calculated delays, enabling listening participants to perform power control signaling as needed.
Another significant patent is "Method and apparatus for providing a dispatch patch service in a CDMA communication system." This invention discloses a method and apparatus that facilitate a dispatch patch service within a CDMA communication framework. A communication unit involved in a dispatch call can request a base site to patch a target, either a dispatch group or an individual, into the current call. By providing the CDMA long-code mask used for the present call to the patch target, a new long-code mask can be generated for ongoing dispatch calls.
