Abstract: A measurement method using a synchronization signal block, a terminal device, and a base station. In the method, a terminal device can determine a first adjustment parameter of a to-be-measured neighboring cell, and determine, based on the first adjustment parameter, a first synchronization signal block-based measurement timing configuration SMTC window corresponding to the to-be-measured neighboring cell. Then, the terminal device measures the to-be-measured neighboring cell based on the first SMTC window.

Abstract: A communication method and apparatus. A terminal device determines, based on first information received from a first network device, that a second network device has first time information, where the first time information is time information having precision that is higher than precision of second time information of the first network device. The terminal device obtains the first time information of the second network device based on the first information. The terminal device obtains high-precision time information to improve communication reliability.

Abstract: A radio resource control (RRC) connection resume method includes receiving, by a first network device, an RRC connection resume request message from a terminal device. The RRC connection resume request message is used to request to resume an RRC connection of the terminal device. The method also includes sending a first message to a second network device. The first message includes auxiliary information. The auxiliary information includes at least one of information used by the terminal device to perform redirection or information used by the terminal device to perform cell reselection, or the auxiliary information indicates that the first network device cannot respond to the RRC connection resume request message of the terminal device. The method further includes receiving an RRC release message from the second network device. The method additionally includes sending the RRC release message to the terminal device.

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.
