    • A wireless communication apparatus which is capable of communicating with a first wireless terminal holding a first data packet by Bluetooth includes a search unit, a first transceiver transmitting, a first controller, and a scheduling unit. The search unit reserves a search, and executing the search. The first transceiver transmits the first and second control packets, and receives the first data packet and a second data packet. The first controller reserves a transmission of the second control packet to the first wireless terminal, the first controller giving instructions to transmit the second control packet to the first transceiver. The scheduling unit accepts the reservation from the first controller and the search unit, the scheduling unit preferentially allowing a transmission of the second control packet compared with the search, and allowing the search when no reservation of the transmission of the second control packet is made.
    • 能够与通过蓝牙保持第一数据包的第一无线终端通信的无线通信装置包括搜索单元,第一收发器发送,第一控制器和调度单元。 搜索单元保留搜索并执行搜索。 第一收发器发送第一和第二控制分组,并且接收第一数据分组和第二数据分组。 第一控制器保留第二控制分组到第一无线终端的传输,第一控制器给出将第二控制分组发送到第一收发机的指令。 调度单元从第一控制器和搜索单元接受预约,调度单元优先地允许与搜索相比发送第二控制分组,并且当不进行第二控制分组的传输的预留时允许搜索。
