    Abstract: Provided are a method for reporting an antenna port weighting vector. The method includes: receiving quantization mode information of weighting coefficients of second vectors configured by a second node, or reporting to a second node quantization mode information of weighting coefficients of the second vectors; and reporting to the second node the second vectors and weighting coefficients of the second vectors quantized according to the quantization mode information; where the quantization mode information includes information indicating a quantization state set; a first vector is an antenna port weighting vector and consists of the second vectors; and the second vectors include at least one of the following vectors: vectors of which elements have a one-to-one correspondence with antenna ports or vectors of which elements have a one-to-one correspondence with reported frequency domain sub-bands.

    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.
