Transmission method for sender and receiver information in wireless asynchronous data transfer system.
1998 (English)Patent (Other (popular science, discussion, etc.))
NOVELTY - The data word of a PDU is encoded as a function of an identification vector, without increasing the bandwidth required for transmission of the PDU from the sender to the receiver. The vector includes a priori identification information regarding the sender and the receiver, and a corresponding data frame is sent from the sender to the receiver. USE - For transmitting sender and receiver information such as access point and wireless terminal identifier data in a wireless asynchronous data transfer system. ADVANTAGE - Ensures that the wireless terminal receives and decodes only intended downlink transmissions. The data integrity and the transmission security are enhanced, without diminishing the bandwidth efficiency. Permits wireless terminal or access point to recognize an unintended data, and enables the discarding of the transmission. DETAILED DESCRIPTION - A protocol data unit (PDU) with a data word is generated at the sender side. An INDEPENDENT CLAIM is also included for receiver status determination method. DESCRIPTION OF DRAWING(S) - The figure indicates the transportation of sender and receiver identification information.
