  • Patent number: 11956067
    Abstract: According to one embodiment, a wireless base station includes a transmitter and a receiver. The transmitter transmits a control signal and one or more operation signals to the second wireless communication terminal. The control signal instructs to transmit a signal that requests terminal-to-terminal communication between a first wireless communication terminal and the second wireless communication terminal. The operation signals are used for operating at least a part of the first wireless communication terminal. The receiver is capable of receiving at least one of a response signal or a data signal transmitted from the first wireless communication terminal to the second wireless communication terminal after the operation signals are transmitted.
