Inventor: HIRANO JUN
IPC: H04W84/12
Filed: 2002-07-08
Abstract: <P>PROBLEM TO BE SOLVED: To enhance a data transmission efficiency in radio communication adopting the TDMA system (in particular, radio communication in compliance with the IEEE802.11 standards) wherein an idle time is provided between data transmitted/received by a radio communication terminal on a radio block.  <P>SOLUTION: The data transmission efficiency is enhanced in the radio communication between radio communication terminals by reducing a transmission time of a header added to data or the idle time. Concretely, the transmission time of the header is reduced by adding the header to the data for each of the prescribed number of times of transmission data and transmitting the other data without adding the header to them, for example. Further, the data transmission efficiency is enhanced by performing a method of acquiring the header of the data on the radio block in advance, a method of utilizing identification information as the header, or a method of attaining transmission of consecutive data by reducing an IFS (interframe space) after Ack (reception confirmation information) or the like.  <P>COPYRIGHT: (C)2004,JPO
