Common signalling mode for use with multiple wireless formats
View Patent ↗A method is provided for operating a wireless local device. In this method a local device receives a beacon for a current superframe in a common signal format. The beacon includes time slot assignment information. The local device then determines a device format for the transmission of data to a remote device based on format determination information. The device format can be one of a common signal format, and one or more wireless formats. The local device then determines one or more remote device time slots in the superframe assigned for transmission of the data to the remote device based on the time slot assignment information. Finally, the local device transmits the data in the one or more remote device time slots to the remote device using the device format.
