Patent ID: 8792431

Claim:
A wireless communication apparatus comprising: a first signal communicating unit that receives a first signal of a first wireless communication system or transmits, based on allocation information of a wireless communication resource which information is transmitted in a predetermined cycle, the first signal of the first wireless communication system; a second signal communicating unit that receives or transmits a second signal of a second wireless communication system different from the first wireless communication system; and a controller that: restricts the first signal communicating unit to transmit the first signal of the first wireless communication system using the wireless communication resource and allows the second signal communicating unit to transmit or receive the second signal in a period of a first frame among a plurality of frames composing a TDM controlling cycle, the period during which the allocation information is not transmitted; does not restrict the first signal communicating unit to transmit the first signal of the first wireless communication system using the wireless communication resource allocated by the allocation information in any frame, among the plurality of frames, other than the first frame; and performs a retransmission control for retransmitting the first signal, which is not correctly transmitted or received in the first frame, in at least one frame, among the plurality of frames, subsequent to the first frame, wherein the controller withdraws the restriction by the time the controller receives the allocation information transmitted in the predetermined cycle after the controller starts the restriction, and wherein the controller receives a request to retransmit data which is not correctly transmitted or received during the restriction and the controller transmits, based on the allocation information received after the withdrawal of the restriction, the data in response to the request.
