A power outage processing method: receiving, by a controller in a base station, notification information sent by a first power source, where the notification information is used to indicate that a power outage has occurred on the first power source; the base station includes M radio units, and the M radio units are supplied with power by N power sources, where each power source is connected to at least one radio unit; and the first power source is one of the N power sources, and the N power sources are all supplied with power by using a power grid, determining, by the controller based on connection relationships between the N power sources and the M radio units, a radio unit connected to the first power source; and instructing, by the controller, all or some of radio units connected to the first power source to reduce power consumption.

This application provides a signal transmission method, a terminal device, and a network device. The method includes: determining, by a terminal device, a first transmit power based on an access status of the terminal device at a current coverage level and/or a first power control parameter; and transmitting a signal at the first transmit power.

This application discloses a data transmission solution. A terminal device generates channel state information and data for transmission in a data channel. The transmit power of the data channel is determined based on the number of bits used to transmit the data and the number of bits used to transmit the channel state information. The solution of this application reduces bit error probability and improves data decoding accuracy.

Aspects of the subject disclosure may include, for example, segmenting an assigned spectrum into a lower portion, a middle portion, and an upper portion, establishing one or more full power wireless connections in the middle portion of the assigned spectrum, and establishing one or more reduced power wireless connections in the upper and lower portions of the assigned spectrum. Other embodiments are disclosed.

This disclosure relates to apparatus and methods for radio-frequency (RF) switching circuits, and more particularly for a PIN diode driver circuit for high speed, high repetition rate and/or high power applications. The PIN diode driver may include a dual voltage reverse bias provided to the PIN diode, which dual voltage reverse bias may be provided by a first, relatively lower voltage, power supply and a second, relatively higher voltage, power supply. The relatively lower voltage is to discharge an intrinsic layer of the PIN diode at a lower voltage than during reverse bias of the PIN diode at the second relatively higher bias voltage in order to reduce overall power consumption.
