Channel quality measurement and feedback method and apparatus

Abstract

Embodiments of the present invention provide a channel quality measurement and feedback method and apparatus. The method includes: receiving K reference signals sent by a transmit end, performing channel quality measurement based on the K reference signals, determining L pieces of channel state information CSI based on a measurement result, and sending the L pieces of CSI to the transmit end. K is a positive integer, L is a positive integer, and each of the L pieces of CSI includes index number information of J sub-bands, or each of the L pieces of CSI includes index number information of P reference signals, J is a positive integer, and P is a positive integer. In the embodiments of the present invention, a method for measuring channel quality based on a reference signal can improve system performance.
