Abstract

The present invention relates to a method for reporting a channel state in a wireless communication system according to one embodiment of the present invention, wherein a terminal can retune between a plurality of narrowbands and receive data, and the method may comprise the steps of: receiving a configuration for reporting a channel state; calculating a channel quality indicator for all the plurality of narrowbands if a periodical broadband feedback mode is configured according to the configuration for reporting a channel state; and reporting the calculated channel quality indicator.

Description

technical field [0001] The present disclosure relates to wireless communication systems, and more particularly, to methods and apparatus for reporting channel status. Background technique [0002] Various technologies including machine-to-machine (M2M) communication and various devices requiring high data rates, for example, smart phones and tablet personal computers (PCs) have appeared and are gaining popularity. Consequently, the amount of data to be processed in cellular networks is growing rapidly. In order to meet such rapidly increasing data processing requirements, carrier aggregation (CA), cognitive radio, etc. for effectively using a greater number of frequency bands have been developed for increasing the amount of data transmitted in a limited frequency band Multiple Input Multiple Output (MIMO), Coordinated Multipoint Transmission and Reception (CoMP), etc. Furthermore, the communication environment is evolving towards an increased density of nodes accessible by...
