Abstract: The disclosure provides a power adjustment method and apparatus for adjusting power of a serving cell. The serving cell sends a first message to a first terminal to indicates to configure a first measurement bandwidth as a center bandwidth, where a frequency range of the center bandwidth is less than a frequency range of a full bandwidth, the full bandwidth represents a maximum bandwidth allocated to the serving cell, and the first measurement bandwidth is used by the first terminal to measure channel quality; the serving cell reduces power in a second bandwidth, where a frequency range of the second bandwidth is a frequency range obtained by subtracting the frequency range of the center bandwidth from the frequency range of the full bandwidth; and the serving cell increases power in the center bandwidth. The increase of the power in the center bandwidth can increase a coverage of the serving cell.

Abstract: Embodiments of this application provide antenna switching methods and apparatuses. In an implementation, a first communication device determines a first antenna identifier based on air interface transmission information, the first communication device sends the first antenna identifier to a digital switch, and the digital switch switches from a second switch state to a first switch state based on the first antenna identifier, where the first switch state indicates that a second communication device communicates with the first antenna within a first time unit, and the second switch state indicates that the second communication device communicates with a second antenna within a second time unit.
