Abstract: The disclosure provides a method and device used for node in wireless communication. The first node first receives a first reference signal and a second reference signal, then determines a first power within a range not greater than a first maximum power, and finally transmits 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. Through determining an upper limit of a transmitting power on a sidelink using a measurement result against a cellular network link, the disclosure can reduce interferences to the cellular network while ensuring the sidelink performance, and can optimize the transmitting power on the sidelink to reduce the power consumption of the terminal, thereby improving the overall performance of the system.

Abstract: The present disclosure provides a method and a device in a User Equipment (UE) and a base station used for wireless communications. The UE receives first information; determines first sub-information out of the M piece(s) of sub-information; receives a first radio signal in a first time-frequency resource set; the first information comprises the M piece(s) of sub-information, each of the M piece(s) of sub-information indicates a reference signal group, and a reference signal group comprises at least one reference signal. The first sub-information indicates a first reference signal group. A reference signal in a reference signal group indicated by at least one of the M piece(s) of sub-information is transmitted by a first serving cell, and the first serving cell is not added by the UE. The above method not only obtains performance advancement brought by serving cell handover, but also avoid time delay and service interrupt.
