Provided are a data processing method, node and terminal. The method includes: before sending data, a first node performing a perception measurement on a first channel of transmission data within a pre-determined time duration; the first node acquiring a first perception measurement result of the perception measurement; and the first node processing data according to the first perception measurement result. By means of the embodiments of the present application, the problems in the relevant art of an interference between uplink and downlink data transmissions of a neighbor cell or a present cell, and a resource collision can be solved.
