Title:
RADIO COMMUNICATION METHOD, RADIO COMMUNICATION TERMINAL, AND RADIO LAN SYSTEM
Document Type and Number:
WIPO Patent Application WO/2004/006508
Kind Code:
A1
Abstract:
A radio communication method and the like capable of improving the data transmission efficiency in a radio communication by the TDMA method (especially radio communication based on the IEEE802.11 standard) by arranging an empty time between data transmitted/received by a radio communication terminal on a radio interval. In a radio communication between radio communication terminals, by reducing the transmission time of the header added to data and an empty time, it is possible to improve the data transmission efficiency. More specifically, for example, a header is added to data for each predetermined number of data transmissions and the other data are transmitted without adding any header, thereby reducing the header transmission time. Moreover, it is possible to improve the data transmission efficiency by a method for acquiring a header of data on a radio interval in advance, a method for utilizing the identification information as a header, and a method for reducing the IFS (InterFlame Space) after Ack (reception acknowledgement information), thereby enabling continuous data transmission.
