Abstract
Aspects of the disclosure provide a method, an apparatus, and a non-transitory computer-readable medium for compressing channel state information (CSI). Under the method, a CSI matrix is decomposed, at a first device, into a first vector including a plurality of significant numbers extracted from the CSI matrix. A second vector is generated by multiplying the first vector with a linear operator. A length of the second vector is less than a length of the first vector. The second vector is sent from the first device to a second device along with a number of the plurality of significant numbers in the first vector. The method is implemented in software instructions, and when processing circuitry of the apparatus executes the software instructions, the processing circuitry of the apparatus performs the method. The software instructions are stored in the non-transitory computer-readable medium.
