Abstract: A wireless communication method is described for a channel state information reporting method. The reporting method may include a communication node performing the following example operations: (1) Performing differential operation on a sequence of coefficients used to compose the precoding matrix vector with a certain vector, where the differential operation may be performed on adjacent frequency domain units in order to produce a resulting sequence. The sequence of coefficients of the certain vector is a sequence formed by the value of the certain vector's coefficients on the different unit of the frequency domain. (2) The resulting sequence can be transformed to obtain another sequence on another domain. (3) Send back at least some of the data in the another sequence to a network node.
