Provided is a method for selectively performing an uplink scheduling request (SR) by a terminal on the basis of an adaptive uplink channel state threshold value, and an apparatus supporting the same. The terminal may calculate an uplink channel state threshold value on the basis of a variation of a short-term average uplink channel state and a long-term average uplink channel state, determine an uplink channel state predictive value on the basis of a downlink channel state, and determine whether to perform an uplink scheduling request on the basis of the uplink channel state predictive value and the uplink channel state threshold value.

Method and apparatus for performing uplink scheduling request by terminal

Provided are a method by which a terminal selectively performs an operation on the basis of a terminal operation mode in a wireless communication system, and a device for supporting the method. The terminal determines a terminal group to which the terminal belongs, on the basis of a battery residual quantity and a battery residual quantity threshold value, calculates channel quality on the basis of a downlink reference signal, determines a terminal operation mode on the basis of the determined terminal group, the calculated channel quality, and the channel quality threshold value, and performs an operation on the basis of the determined terminal operation mode, wherein the terminal group can be any one of an energy insufficient group (EIG) and an energy sufficient group (ESG).
