Method and device for relay communication in a user equipment or a base station

A method for a user equipment for relay communication, comprising:

• receiving first information, the first information comprising a first power value and a first coefficient;
• and
• transmitting a first wireless signal;
• wherein the product of the first power value and the first coefficient is used to determine a transmission power of the first wireless signal.

A method for a user equipment for relay communication, comprising:

• transmitting second information, wherein the second information comprises a first channel quality;
• and
• receiving a first wireless signal;
• wherein a transmitter of the first wireless signal is a first node;
• the first channel quality is for a channel of the first node to the UE;
• a receiver of the second information comprises a first cell;
• the maintenance base station of the first cell and the first node are non-co-located;
• the first channel quality is used to determine the transmission power of the first wireless signal.
