ABSTRACT:
Disclosed is a frame structure in a high-speed wireless personal area network (WPAN) and a message transmitting method thereof which enable communications among devices existing in different piconets by using a device that provides a bridging function in the IEEE 802.15.3 WPAN. In a high-speed WPAN system which includes a parent piconet having a plurality of devices and a child piconet using time slots allocated by the devices located in the parent piconet, and a bridge device located in the child piconet, that broadcasts information about the devices of the parent piconet and information about the devices of the child piconet to the devices included in the high-speed WPAN, and operates to perform a data transfer between a first specified device in the child piconet and a second specified device in the parent piconet. A specified device included in the high-speed WPAN constructs a MAC (Media Access Control) header data structure for a data transmission so that the data structure includes a source piconet identification (ID) field for indicating the piconet to which the specified device belongs, and a destination piconet ID field for indicating the destination piconet to which the destination device, to which the specified device intends to transmit data, belongs.
