Abstract
In a radio communication system a method and apparatus enables sharing a bandwidth between two protocols that can support different maximum numbers of subchannels (510-516, 602-614) in the bandwidth. The protocols utilize transmission frames (402) having frame durations (716) that are integer multiples of one another. A fixed portion (102) of the system synchronizes (1002) the frames of the two protocols and determines (1004) a sharing plan for the subchannels utilized by each protocol. The sharing plan applies to a subsequent group of frames. The fixed portion vectors (1008) a portable receiver (122, 123) that has a message to be received in accordance with the sharing plan prior to transmission of the subsequent group of frames. Both the fixed portion and the portable receiver share (1010) the bandwidth between the two protocols in accordance with the sharing plan during transmission of the subsequent group of frames.
