  • Patent number: 9332563
    Abstract: A wireless communication includes: a communication unit; a storage unit; a transmission buffer; and a controller. The communication unit wirelessly communicates with a reception terminal. The storage unit stores information relating to a timing at which the reception terminal changes from a first state to a second state. The first state is a state of being able to receive data and continues for a first period. The second state is a state of being unable to receive data and continues for a second period. The first period is extended by a fixed duration when the reception terminal in the first state receives data. The transmission buffer temporarily stores segmented data constituting transmission data to be transmitted to the reception terminal. The controller controls the communication unit to wirelessly transmit dummy data to the reception terminal by the timing if the segmented data is not stored in the storage unit.
