Abstract: Embodiments provide an uplink signal acknowledge method. In the method, an uplink signal sent by a terminal device for tracking the terminal device can be received by a base station or a transmission/reception point (TRP). A downlink tracking acknowledge message can be sent to the terminal device. The downlink tracking acknowledge message can include at least one of the following: information about a status in which the base station or the TRP tracks the terminal device, timing advance information required by the terminal device to send an uplink tracking signal, power adjustment information required by the terminal device to send the uplink signal, and access control information of the terminal device. The base station or the TRP sends the downlink tracking acknowledge message to the terminal device, so that the terminal device learns whether a network has tracked the terminal device.
