Patent ID: 11211984

Abstract:
The present invention relates to a method for reporting a channel state for a narrowband-Internet of Things (NB-IoT) terminal in a wireless communication system, the method, according to one embodiment of the present invention, being executed by a NB-IoT terminal configured so as to operate in a single resource block (BR)-unit NB, and comprising the steps of: receiving, from a base station, a request for the reporting of aperiodic channel state information; according to the request, calculating a channel quality indicator of at least one NB corresponding to a resource for which channel state information is being measured; and transmitting the calculated channel quality indicator to the base station, wherein the channel quality indicator is calculated during a valid subframe interval comprising at least one subframe, wherein the valid subframe interval may exclude a subframe in which a synchronization signal is transmitted from the at least one NB, or a subframe in which the terminal monitors a different NB that is not the at least one NB.
