摘要： Embodiments of this application provide an integrated circuit, a chip, and an electronic device, and relate to the field of microelectronic circuit technologies, to reduce an integrated circuit malfunction caused by electrostatic discharge. The integrated circuit includes a substrate and a transistor disposed on the substrate. A gate of the transistor is coupled to a first end of a switch component, and a second end of the switch component is coupled to a ground end. The switch component is configured to be in a turn-on state or a turn-off state under control of a control signal received by a control end. The switch component in the turn-on state transmits an electrostatic voltage of the gate of the transistor to the ground end. Alternatively, the switch component in the turn-off state disconnects the gate of the transistor from the ground end.

摘要： A subframe configuration switching method and apparatus provided in the present invention relate to the communications field, and are used for subframe configuration switching. Impact of subframe configuration switching on a service of a terminal can be greatly reduced, and therefore service experience of the terminal is improved. The method includes: determining, by a base station, that a subframe configuration of a cell needs to be changed from a first configuration to a second configuration, and notifying a terminal in the cell of the change in the subframe configuration of the cell; sending, by the base station, the second configuration to the terminal in the cell when first duration that is after the notification expires; and making, by the base station, the second configuration effective when second duration that is after the base station sends the second configuration expires, where the base station does not perform initial transmission scheduling on the terminal in the cell within the first duration, and the base station does not schedule the terminal in the cell within the second duration.

摘要： The present invention provides a method and a device for interleaving processing in a WLAN system, and relates to the field of communications technologies. The technical problem to be solved is: when the number of data sub-carriers changes, interleaving parameters change accordingly; therefore, interleaver hardware needs to be modified, thus resulting in a high cost. The method may specifically include: obtaining, by a WLAN device, a predetermined number of identifiers of valid positions from any sub-interleaving processing contained in an interleaving processing; determining valid input positions of the interleaving processing according to the identifiers of the valid positions; transmitting data bits to be transmitted in the valid input positions, and transmitting bit 0 and/or bit 1 or no data bit in other non-valid input positions of the interleaving processing other than the valid input positions; modulating data bits transmitted in interleaving processing output positions to obtain modulation signals and mapping the modulation signals onto the corresponding data sub-carriers respectively. The present invention can be applied in interleaving processing of data bits to be transmitted.

The embodiments of the present invention further provide an antenna system, including a barrel directional antenna array, a radio frequency transceiver, and a baseband signal processing and control unit. Based on the barrel directional antenna array, the antenna system can adjust the quantity of sectors in a 360-degree range based on a change in a service volume in the 360-degree sector, so that an adjusted sector service capacity threshold can accommodate the service volume in the 360-degree sector.

摘要： The present invention provides a dielectric resonator, a dielectric filter, and a method for fabricating the dielectric resonator or the dielectric filter. The dielectric includes: a solid dielectric resonator body, a blind hole located on one side of the solid dielectric resonator body, a metallized layer covering both a surface of the solid dielectric resonator body and a surface of the blind hole, and a demetallized notch located at the metallized layer on the surface of the blind hole. The dielectric resonator provided in the present invention can not only implement tuning of the dielectric resonator, but also reduce impact on the resonance frequency of the dielectric resonator after the dielectric resonator is tuned, where the impact is caused by that the demetallized notch is covered by a metal material in an assembly process of the dielectric resonator, and can further reduce signal energy that is leaked from the notch.
