Method and device used for node in wireless communication

A first node for wireless communication, comprising:

• a first receiver, to receive a first reference signal from a base station and a second reference signal from a terminal equipment;
• a first processor, to determine a first power within a range not greater than a first maximum power;
• and
• a first transmitter, to transmit a first radio signal with the first power;
• wherein:
• the first maximum power is related to a measurement result against the first reference signal and is not related to a measurement result against the second reference signal;
• and the first power is related to the measurement result against the second reference signal;
• the terminal equipment receives the first radio signal;
• the base station and the terminal equipment are non co-located;
• a physical layer channel occupied by the first radio signal comprises a PSSCH;
• the measurement result against the first reference signal comprises a path loss, determined by the first node according to the received first reference signal, from the base station to the first node;
• and
• the measurement result against the second reference signal comprises an RSRP of the second reference signal.

A second node for wireless communication, comprising:

• a second transmitter, to transmit a first reference signal;
• wherein:
• a first maximum power is related to a measurement result against the first reference signal, and is not related to a measurement result against a second reference signal transmitted from a terminal equipment;
• the first reference signal and the second reference signal are received by a first node;
• the terminal equipment receives a first radio signal transmitted from the first node to transmit the second reference signal, wherein a first power of the first radio signal is related to the measurement result against the second reference signal;
• the first power is within a range not greater than the first maximum power;
• the second node is a base station;
• the second node and the terminal equipment are non co-located;
• a physical layer channel occupied by the first radio signal comprises a PSSCH;
• the measurement result against the first reference signal comprises a path loss, determined by the transmitter of the first radio according to the received first reference signal, from the second node to the transmitter of the first radio signal;
• and
• the measurement result against the second reference signal comprises an RSRP of the second reference signal.
