摘要： 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.

摘要： A method and device for estimating the time of arrival (ToA) of a radio signal are proposed. The radio signal comprises M subsignals carried on M subcarriers, where M is an integer ≥2. The number of propagation paths and the time of arrival associated with a first path are estimated. The technique can improve ToA estimation accuracy, especially in a multipath fading channel, and reduce the need for channel information.
