摘要： The present disclosure provides a method and a device in a node used for wireless communication. A first node receives a first information element, the first information element being used for indicating a first reference power value; and receives a second information set, the second information set comprising a second information element, the second information element being used for indicating a second limit power value; and transmits a first radio signal with a first power value; a target receiver of the first radio signal includes a transmitter of the first information element, the first power value is related to a smaller value between the first reference power value and the second limit power value. Taking into account restrictions resulted from interference when adjusting a transmitting power of a desired signal, the present disclosure can address interferences that may occur in V2X system in unicast or groupcast transmission.

摘要： The present application discloses a method and a device in a node for wireless communications. A first node receives a first signaling group, the first signaling group being used to indicate a first signature sequence group and a second signature sequence group; transmits a first signature sequence in a first time interval; and transmits a second characteristic sequence in a second time interval; whether the first signature sequence belongs to the first signature sequence group or the second signature sequence group is used for selecting the second signature sequence; any signature sequence in the first signature sequence group is associated with a shared channel resource unit in a first period. The present application avoids the situation where the first node persistently selects random access preambles without being associated with a shared channel resource unit, thus ensuring that the requirement on access delay for UE is satisfied.
