Abstract: The present disclosure discloses a method and a device in nodes used for wireless communications. A first node first receives a first radio signal and a second radio signal; and then determines that transmitting power of first control information in a first time window is a first power value and transmitting power of second control information in a second time window is a second power value; and transmits the first control information in the first time window with the first power value; the first power value is unrelated to the second power value, and the second power value is relevant to whether the first time window overlaps with the second time window. The present disclosure designs power allocation priorities of first control information and second control information to optimize both transmission performance and efficiency of a feedback channel in sidelink.

Abstract: The present disclosure discloses a method and device for narrowband mobile communication in wireless communication. The base station transmitting first information, wherein the first information comprising a first power value and a first coefficient, transmitting a second wireless signal. The product of the first power value and the first coefficient is used to determine the transmission power of the first wireless signal. The transmitter of the first wireless signal is a first node. The present disclosure enables the transmitting UE to have a lower transmission power to ensure the receiving performance of the relay UE. In addition, the present disclosure can simultaneously reduce interference of data reception for the conventional UE on the base station side, thereby improving overall system performance.
