Abstract:
A hybrid channel quality measurement method is presented. The method includes: performing a first channel measurement according to Channel State Information Reference Signals (CSI-RSs), and transmitting a first channel measurement feedback to a base station according to a first channel measurement result; determining whether to perform a second channel measurement feedback based on Demodulation Reference Signals (DMRSs) after the first channel measurement feedback is performed; and performing a second channel measurement according to the DMRSs when determining to perform the second channel measurement feedback, and transmitting the second channel measurement feedback to the base station according to a second channel measurement result.
