Method, device, and system for notifying information about power difference

A terminal device, comprising:

• a transceiver;
• and
• one or more processors in communication with the transceiver and to a non-transitory memory storage, wherein the one or more processors execute computer-executable instructions of the non-transitory memory storage to cause the one or more processors to perform operations comprising:
• receiving, by the transceiver, first information from a network device, wherein:
• the first information is used to indicate a first power difference, the first power difference is associated with a first waveform, and the first power difference comprises an offset between a power of a reference signal and a power of a first physical downlink shared channel (PDSCH) on which the first waveform is used;
• and
• the first information is used to indicate a plurality of power differences, and at least two of the plurality of power differences correspond to different waveforms;
• and
• obtaining the first power difference.

A method for notifying information about a power difference, comprising:

• determining, by a network device, first information, wherein:
• the first information is used to indicate a first power difference, the first power difference is associated with a first waveform, and the first power difference comprises an offset between a power of a reference signal and a power of a first physical downlink shared channel (PDSCH) on which the first waveform is used;
• and
• the first information is used to indicate a plurality of power differences, and at least two of the plurality of power differences correspond to different waveforms;
• and
• sending, by the network device, the first information to a terminal device.

A method for notifying information about a power difference, comprising:

• receiving, by a terminal device, first information from a network device, wherein:
• the first information is used to indicate a first power difference, the first power difference is related to a first waveform, and the first power difference is an offset between a power of a reference signal and a power of a first physical downlink shared channel PDSCH on which the first waveform is used;
• and the first information is used to indicate a plurality of power differences, and at least two of the plurality of power differences correspond to different waveforms;
• and
• obtaining, by the terminal device, the first power difference.
