  • Publication number: 20190302230
    Abstract: A disclosed method includes: dividing an signal into a first signal and a second signal; performing frequency multiplication and amplification on the first signal to obtain an intermediate signal of corresponding power and frequency, and using the second signal as a local oscillation signal. The method further includes dividing the intermediate signal into a first intermediate signal and a second intermediate signal, and using the first intermediate signal as a reference signal; performing frequency mixing on the second intermediate signal and the local oscillation signal to obtain a mixed signal, which is a high-frequency millimeter wave signal; transmitting the mixed signal by a transmitting antenna; and performing frequency mixing on the signal received by a receiving antenna and the reference signal to obtain an intermediate-frequency controllable signal having a frequency consistent with that of the output signal of the signal source.

  • Patent number: 10375582
    Abstract: A mobile device transmits data over a shared spectrum in an uplink channel to a base station in a contention-based access scheme. The mobile device obtains data to be wirelessly transmitted over the shared spectrum in the uplink channel to the base station. The uplink channel is formatted with a frame/subframe structure with a predetermined timing. The mobile device determines whether the shared spectrum is free for transmission according to a listen before transmit procedure. When the shared spectrum is free for transmission, the mobile device contends with other mobile device to gain access to the uplink channel. After gaining access to the uplink channel, the mobile device transmits the data over the shared spectrum in the uplink channel to the base station.
