Base station and radio terminal

A base station for a wireless LAN system realizing band-widening using a plurality of communication channels, the base station comprising:

• a plurality of physical layers corresponding to the plurality of communication channels, and each that transmits and receives a radio signal conforming to an IEEE 802.11 standard using a corresponding communication channel;
• and
• a media access control (hereinafter, “MAC”) layer,
• when transmitting, that divides an entire data frame conforming to the IEEE 802.11 standard from a head of the data frame, in accordance with a transmission rate of each physical layer, and allots the divided data frame to the physical layers so that burst times of the communications channels are substantially equal, and
• when receiving, that combines data frames received via a plurality of communication channels through operations opposite to those performed when transmitting.
