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.
