摘要： The disclosure provides a method and a device in a node for wireless communication. A first node first receives a first radio signal and a second radio signal, and transmits first information when a trigger condition is met. The first radio signal and the second radio signal are used for determining a channel quality of a first link and a channel quality of a second link respectively, the channel quality of the first link and the channel quality of the second link are used together for determining the trigger condition. The first information comprises a first parameter, and the first parameter is applied only to the first link of the first link and the second link. According to the above design, the triggering of PHR for a sidelink in V2X systems is associated with both the channel quality of the sidelink and the channel quality of a cellular link.

摘要： The present disclosure provides a method and a device in a first node for wireless communication. The first node first performs a monitoring on first-type signalings, in which K1 first-type signalings are detected; and then transmits a first radio signal in a first time-frequency resource set; each of the K1 first-type signalings is associated to the first time-frequency resource set; a first signaling is a last first-type signaling of the K1 first-type signaling; the first radio signal is used for determining the receiving of first-type signaling(s) associated to the first time-frequency resource set before the first signaling; or is used for determining the decoding of bit blocks scheduled by the K1 first-type signalings. With the above-mentioned designs, the present disclosure manages to address missed detection of sidelink scheduling signaling caused when a data receiver sends NACK-only feedback in V2X, thereby further improving the entire system performance.

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, interferences that may occur in V2X system in unicast or groupcast transmission are addressed.
