Abstract
In a time division, multiple access system, a base station (102) transmits an isochronous beacon (404, 422) at the start of each frame (400), conveying control and timing information. Following the isochronous beacon (404), isochronous time slots (414, 416, 418, 420) are dynamically allocated for communication of isochronous data. After communication of the isochronous data, the remainder of the frame (400) before the next isochronous beacon (422) is used for transmission of packets of asynchronous data. This technique gives priority to the isochronous data, which is real time, while also maximizing the bandwidth allocated for asynchronous data. A single transmitter circuit (124, 158) and receiver circuit (122, 156) at each station are used for communication of both isochronous data and asynchronous data.
