Abstract: This application discloses example power control methods and apparatuses. One example method includes receiving, by a first node, first information sent by a second node, where the first information is used to determine a first transmit power, where the first transmit power is a power used when the first node sends downlink information to the second node through a first link, where the first link is a link between the first node and the second node, and where the first node is an upper-level device of the second node. The first node can then determine the first transmit power based on the first information.

Abstract: This application provides a cell selection method and apparatus, to resolve abnormal wireless communication between a terminal device and a selected cell. The method includes: A terminal device may obtain a first offset of at least one first to-be-selected cell. The first offset is used to determine a cell selection parameter of the at least one first to-be-selected cell. The cell selection parameter includes a cell selection receive level value Srxlev and/or a cell selection receive quality value Squal. Next, the terminal device may determine, based on uplink capability as to whether the terminal device can perform uplink enhancement, the cell selection parameter of the at least one first to-be-selected cell by using the first offset. Then, the terminal device may determine a first cell from the at least one first to-be-selected cell based on the cell selection parameter.

Abstract: This application provides a cell reselection method, a terminal device, and a network device. The terminal device may be a low-bandwidth terminal device, so that a time period for the terminal device to perform cell reselection is reduced, and power consumption of the terminal device is reduced. The method includes: The terminal device receives first indication information sent by the network device, where the first indication information indicates information about an initial bandwidth part of a first cell, the first cell is a neighboring cell of a second cell, and the second cell is a cell on which the terminal device currently camps. The terminal device determines, based on a type of the terminal device and the first indication information, whether to reselect to the first cell.
