摘要： 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.

摘要： The present disclosure discloses a method and device used in wireless communication node. A first node receives first information and second information via an air interface, the first information indicating a first time offset value, and the second information indicating a first time-domain resource relative to a first instant of time; the first instant of time is associated with a first time unit. By designing the first time offset value in the present disclosure, whenever a terminal A expects a terminal B to transmit, the terminal B is able to transmit according to a timing obtained by itself and there is no need for multiple interactions between these terminals to acquire a timing advance (TA), thus improving radio signal transmission efficiency on sidelink in IOT and V2X systems and the system's overall performance.

摘要： The disclosure provides a method and a device in a node for wireless communication. A first node first receives a first bit field and Q second-type bit field(s), and then transmits L radio signal(s) at a first power value; the first bit field is used for determining a first reference signal resource set; each of the Q second-type bit field(s) indicates one power offset; the first power value is only related to power offsets indicated by all second-type bit fields among the Q second-type bit field(s) that correspond to a first index, and the first index is one of K1 indexes associated to the first reference signal resource set; and the first index is related to the L reference signal resource set(s). Multiple times of repetition based uplink transmissions employ a uniform power control mechanism under multiple beams, which reduces hardware requirements at terminal side and improves transmission performance.
