Wake-up signal transmission method and apparatus
By allowing the terminal device to select appropriate resources between PRACH resources and chirp signal resources to send the uplink wake-up signal, the problem of increased power consumption in 5G terminals is solved, achieving energy saving and reducing the complexity of network device detection.

Abstract
A wake-up signal transmission method and apparatus. In the method, a terminal device determines a third resource from a first resource and a second resource, on the basis of a service requirement of the terminal device and / or the position of the terminal device. The terminal device sends an uplink wake-up signal to a network device using the third resource. The first resource is a resource dedicated to transmitting an uplink wake-up signal in a physical random access channel (PRACH) resource, and the second resource is a resource corresponding to a chirp signal. The method enables the terminal device to select a suitable resource from the first resource and the second resource to send the uplink wake-up signal, making it possible to achieve energy saving while ensuring service performance.
