AI Technical Summary

Technical Problem

In MIMO evolution scenarios, the UE cannot measure the path loss between multiple TRPs and the UE, especially when the auxiliary TRP does not send downlink signals, making it impossible to obtain accurate path loss.

Method used

The terminal device obtains and filters the signal power estimation results it sends, and then sends power information to the network device. The network device calculates the path loss difference based on the received power estimation results and the power information. Finally, the terminal device obtains the path loss between each TRP and itself.

Benefits of technology

It enables accurate acquisition of path loss between terminal devices and multiple TRPs in DL single-TRP and UL multi-TRP scenarios, improving the reliability and accuracy of uplink signal measurement.

Abstract

Provided in the embodiments of the present application are path loss acquisition methods, devices, a communication apparatus and a medium. A terminal device can acquire a path loss between the terminal device and a network device. A path loss acquisition method comprises: acquiring a first transmission power estimation result corresponding to a first signal and a second transmission power estimation result corresponding to a second signal, the first signal being a signal sent by a terminal device to a first network device, and the second signal being a signal sent by the terminal device to a second network device; sending first power information to the first network device and / or the second network device, the first power information being determined on the basis of the first transmission power estimation result and the second transmission power estimation result; and receiving first information from the first network device, the first information being used for indicating a difference value between a first path loss and a second path loss, the first path loss being a path loss between the first network device and the terminal device, and the second path loss being a path loss between the second network device and the terminal device.
