According to an embodiment, a wireless communication apparatus includes a packet generator, a queue unit, a predictor and a scheduler. The packet generator packetizes data. The queue unit temporarily stores a packet to be transmitted. The predictor predicts a transmission time of a first packet to obtain a first time. The scheduler outputs a second packet to the queue unit at a second time earlier than the first time. An interval from a third time when transmission of the second packet is complete until the first time is equal to or shorter than a predetermined period.
