Claim Text:
1. A method for performing communication by a terminal in a wireless communication system, the method comprising: estimating an energy consumption level of the terminal for a current modulation and coding scheme (MCS) level used for the terminal, and configuring first information indicating the energy consumption level for the current MCS level; estimating a plurality of energy consumption levels of the terminal for a plurality of candidate MCS levels applicable to the terminal, and configuring second information indicating the plurality of energy consumption levels for the plurality of candidate MCS levels; transmitting a parameter related to energy consumption to a base station (BS), wherein the parameter related to energy consumption includes the first information, the current MCS level, the second information, the plurality of candidate MCS levels, a precoding matrix indicator (PMI), and a rank indicator (RI); after transmitting the parameter, transmitting a bandwidth request message or a scheduling message to the BS; after transmitting the bandwidth request message or scheduling message, receiving, from the BS, information regarding a communication technique determined based on the parameter; and performing communication with the BS according to the determined communication technique, wherein the transmitting of the parameter related to energy consumption of the terminal to the BS is performed only when a remaining battery capacity of the terminal is equal to or less than a threshold value.
