Abstract: Disclosed by the present application are a method and device used in a node for wireless communication. A first node receives a first reference signal in a first time unit; first channel information is sent in a second time unit. The measurement of the first reference signal is used for generating the first channel information; said first channel information indicates the first channel quality; if the first bit block occupies a first reference resource block and the average receive power on each RE is a first power value, then the first bit block using the transmission mode corresponding to the first channel quality can be received by the first node having a transmission block error rate which does not exceed a first threshold; the first power value is related to the measurement of the first reference signal. The described method prevents the situation wherein when one node sends a reference signal to another node in Sidelink, ambiguity between the two nodes' understanding of the CSI arises because of the change in transmission power.
