Abstract
A wireless communication method and apparatus for the same performs access control in the following manner, where an acquisition of a right to transmit is performed by CSMA access control method, and a collision of transmitted data packets among different communication apparatuses is prevented for facilitating a stable transmission of data packets from each of the apparatuses in a predetermined interval. The transmission of a data packet having a predetermined data length under a cyclical access control sets an access control start time at a time that is after a lapse of predetermined amount of time from the previous acquisition of the right to transmit. As a result, the competition of the right to transmit is resolved due to a different access control start time set for the next transmission.
