摘要： This is disclosed a communication apparatus. A receiving unit receives plural data frames which are transmitted from other communication apparatus. An error detection unit checks whether each data frame is received correctly or incorrectly. A determination unit estimates a first overhead and a second overhead and determines whether or not to send a block acknowledgement frame by comparing the first and the second overheads. The determination unit estimates the first overhead being caused by sending the block acknowledgement frame and the second overhead being caused by not sending the block acknowledgement frame. The receiving unit receives the data frames which are retransmitted from the other communication apparatus after a certain period of time has passed without sending the block acknowledgement frame, the data frames retransmitted from the other communication apparatus including both data frames which are correctly received and incorrectly received.
