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. ## Claims ### Claim 1 A measurement method, comprising: after receiving, by a terminal device, a first measurement request from a device initiating a first measurement task, and before the first measurement task ends, receiving, by the terminal device, a second measurement request from a device initiating a second measurement task, wherein the first measurement request comprises a first priority of the first measurement task, and the second measurement request comprises a second priority of the second measurement task;
