Method for bi-directional communication between source device and destination device during allocated channel time

摘要

A method and device for bidirectionally transmitting and receiving data during an allocated channel time using a CSMA/CA contention system are provided. The method includes receiving a first data frame from the destination device, transmitting an acknowledgement (ACK) to the destination device, checking whether a channel is idle for a predetermined waiting time, after the source device transmits the ACK to the destination device, and transmitting a second data frame to the destination device if a channel is idle for a predetermined waiting time.
