Abstract: A communication apparatus determines a serving cell that can perform information synchronization with a to-be-activated SCell, where the serving cell is an activated cell or a known cell. The communication apparatus determines a first SSB in SSBs sent by the to-be-activated SCell, where the first SSB corresponds to a second SSB sent by the serving cell. The communication apparatus activates the to-be-activated SCell based on the first SSB sent by the to-be-activated SCell and timing information and beam information of the second SSB.

Abstract: Embodiments of the present invention relate to the field of mobile communications technologies, and in particular, to an indoor positioning method and an apparatus. In this solution, a positioning server obtains floor numbers of floors on which at least one base station is located; the positioning server receives identification information of a first terminal; the positioning server determines the first terminal according to the identification information; and the positioning server determines vertical location information of the first terminal according to the floor numbers of the floors on which the at least one base station is located. When a terminal is located indoors, positioning is meaningful only when a specific floor on which the terminal is located is determined.

Abstract: This application discloses a measurement method and a device, to resolve the following problem: A collision occurs in a process of performing two measurement tasks by a terminal device, affecting measurement efficiency of the terminal device. In this method, after the terminal device simultaneously or successively receives measurement requests sent by devices initiating two measurement tasks, the terminal device may preferentially perform any one of the two measurement tasks, thereby ensuring completion quality of the measurement task. In this way, when devices initiating two measurement tasks instruct the terminal device to perform the two corresponding measurement tasks, a collision can be avoided in a process of performing the two measurement tasks by the terminal device, thereby ensuring measurement efficiency of the terminal device.
