Abstract:
A communication method for a CSMA network including a radio terminal and a base station supporting RTS/CTS, includes: the base station transmitting an RTS frame to the radio terminal during a transmission-suspend-period in which the radio terminal suspends transmission to prevent a collision of packets; the radio terminal transmitting an RTR frame to the base station after the transmission-suspend-period has elapsed; and the base station transmitting a data frame to the radio terminal in response to the RTR frame.
