METHOD AND DEVICE FOR MEASURING CHANNEL QUALITY

摘要

A method and a device for measuring channel quality are provided. The method includes: receiving first signal characteristic information and second signal characteristic information sent by a network side, where the first signal characteristic information is used to indicate a first signal, and the second signal characteristic information is used to indicate a second signal; receiving a downlink signal sent by each node in multiple nodes, obtaining a downlink channel response and downlink interference of each node respectively according to the first signal and the second signal in the downlink signal sent by each node; obtaining downlink channel quality information of each node according to the downlink channel response and the downlink interference of each node; and reporting the downlink channel quality information of each node to the network side. According to embodiments of the present invention, overheads for the node to send signaling is greatly lowered.
