Patent ID: 10218477

Abstract:
Embodiments of the present application disclose a method and an apparatus for determining channel quality. The method comprises: at the same time when a data symbol is sent to a receiver by using a channel, receiving at least one reference signal by using the channel; and determining, at least according to the at least one reference signal, quality of the channel at a corresponding moment when the data symbol is sent to the receiver. The method and the apparatus in the embodiments of the present application can avoid delay and latency problems in estimation of channel quality because a reference signal and data are separately sent in different subframes, thereby improving the real-time performance and accuracy of determining channel quality; moreover, the granularity of determining channel quality is within a same subframe or even each symbol, and in this way, in a process of transmitting a piece of data, quality of a radio channel at different moments may be estimated, so that changes of the quality of the radio channel during an entire sending time can be determined more precisely.
