The present disclosure relates to a method and apparatus for pushing subscription data in Internet of things. The method includes: parsing a subscription condition set into a first attribute set in response to receiving the subscription condition set; acquiring device data; parsing the device data into a second attribute set; performing Bloom filtering on attribute elements in the second attribute set one by one in a predetermined order by taking an attribute element set in the first attribute set as a filter condition; stopping the Bloom filtering on the other attribute elements in the second attribute set in the case that a Bloom filtering result of one attribute element indicates an occurrence of mismatch; and returning to the step of acquiring the device data.

Embodiments of the present disclosure disclose a radio remote unit, a receiver, and a base station. The radio remote unit includes at least one receive channel pair, a first local oscillator module, a second local oscillator module, a local oscillator switching switch, and a controller. Each receive channel pair includes a first receive channel and a second receive channel. Each receive channel in each receive channel pair includes a filtering module, a frequency mixing module connected to the filtering module, and a digital processing module connected to the frequency mixing module. A frequency mixing module on the second receive channel is connected to the first local oscillator module and the second local oscillator module by the local oscillator switching switch. The controller is configured to receive an operating mode that is sent by a base station, and control the local oscillator switching switch to perform switching.

Present application provides embodiments of a transmitter and an interference cancellation method. The transmitter includes: a first digital predistorter (DPD), a power amplifier (PA), and a first processor located on a feedback channel of the transmitter and separately connected to the PA and the first DPD. The first processor performs, according to a feedback cancellation signal, interference cancellation on a signal of the feedback channel, to acquire a first mixed signal, and sends the first mixed signal to the first DPD. The first DPD is configured to perform linear predistortion processing according to a first baseband signal on a first transmit channel and the first mixed signal, to generate a first predistortion signal. The PA is configured to amplify and then transmit a to-be-transmitted signal using an antenna. The to-be-transmitted signal is the first predistortion signal or a signal obtained according to the first predistortion signal.
