Embodiment 1
[0085] The present invention is based on a communication model of a piconet in a high-speed wireless network, and a digital signal processor (DSP) (1) is used to provide functions such as generation and analysis of frames in a media access control layer (MAC), which is equivalent to providing media access control layer control Function of the entity (MLME). The Field Programmable Gate Array (FPGA) (2) is mainly used for baseband processing, codec and time synchronization between physical layers, which is equivalent to providing the functions required by the Physical Layer Control Entity (PLME).
[0086] figure 1It is a system block diagram of a wireless communication device for a beacon frame relay method in a high-speed wireless personal area network of the present invention. The resource exchange center (1-1) of the protocol stack deframes and assembles the data packets from the upper-layer application module, as well as stores and schedules the data frames. The external m...

The invention discloses a method for beacon frame relay in a high-speed wireless personal network, which is characterized by comprising the following steps: making a request of beacon frame relay for other wireless communication equipment in a superframe channel competition visit period by wireless communication equipment, packaging a beacon frame and corresponding control information into a relay response frame after a beacon request frame is received by other wireless communication equipment, sending back the wireless communication equipment in which the beacon frame is lost, and obtaining a channel distribution list and time synchronous information by the wireless communication equipment in which the beacon frame is lost through the beacon frame and time offset information carried by the relay response frame. The spatial gain of a wireless environment and an existing protocol reserved interface are utilized by the beacon frame relay method of the invention, the system expense is less, the acceptance rate of the beacon frame of the wireless communication equipment is improved, and the system robustness is finally improved.
