Abstract
The present disclosure relates to methods for controlling a transmitted power of a sidelink communication and belongs to the communication field. The method includes the followings: when V2X communication is conducted between a first UE and a second UE, the first UE obtains a transmitted power of a reference signal from the second UE and measures a received power of receiving the reference signal by the second UE; the first UE determines a path loss based on a difference between the received power and the transmitted power of the reference signal, and determines a transmitted power of the first UE conducting V2X communication with the second UE based on the path loss.

A method for controlling a transmitted power of a sidelink communication, being applied to a first user equipment (UE) in a vehicle to everything (V2X) and comprising:
- obtaining, by the first UE, a transmitted power of a second UE sending a reference signal;
- measuring, by the first UE, a received power of receiving the reference signal sent by the second UE;
- determining, by the first UE, a path loss based on a difference between the first transmitted power and the received power of the reference signal;
- determining, by the first UE and based on the path loss, a second transmitted power of the first UE conducting V2X communication with the second UE,
- wherein determining, by the first UE, the path loss based on the difference between the first transmitted power and the received power of the reference signal, comprises:
- determining, by the first UE, a path loss of a first communication from at least two candidate path losses based on a priority sequence.
A method of controlling a transmitted power of a sidelink communication, being applied to a first user equipment (UE) in a vehicle to everything (V2X) and comprising:
- measuring, by the first UE, a received power of a reference signal sent by a second UE;
- sending, by the first UE, the received power to the second UE;
- receiving, by the first UE, a path loss from the second UE, wherein the path loss is determined by the second UE for the first UE conducting V2X communication with the second UE;
- determining, by the first UE and based on the path loss, a transmitted power of the first UE conducting V2X communication with the second UE,
- wherein the method further comprises:
- determining, by the first UE, a path loss of a first communication from at least two candidate path losses based on a priority sequence.
A terminal, comprising:
- a processor;
- a transceiver connected to the processor;
- wherein the processor is configured to:
- obtain, by the first UE, a first transmitted power of a second UE sending a reference signal;
- measure, by the first UE, a received power of receiving the reference signal sent by the second UE;
- determine, by the first UE, a path loss based on a difference between the first transmitted power and the received power of the reference signal;
- determine, by the first UE and based on the path loss, a second transmitted power of the first UE conducting V2X communication with the second UE;
- and
- measure, by the first UE, a received power of a reference signal sent by a second UE;
- send, by the first UE, the received power to the second UE;
- receive, by the first UE, a path loss from the second UE, wherein the path loss is determined by the second UE for the first UE conducting V2X communication with the second UE;
- determine, by the first UE and based on the path loss, a transmitted power of the first UE conducting V2X communication with the second UE,
- wherein determining, by the first UE, the path loss based on the difference between the first transmitted power and the received power of the reference signal, comprises:
- determining, by the first UE, a path loss of a first communication from at least two candidate path losses based on a priority sequence.
