Abstract: A method and apparatus for transmitting a power headroom report (PHR) in a wireless communication system is provided. A user equipment (UE) transmits a first PHR for a first carrier group, which is configured by a first eNodeB (eNB), to a second eNB; and transmitting a second PHR for a second carrier group, which is configured by the second eNB, to the first eNB. Te first PHR and the second PHR include a PHR for a physical uplink control channel (PUCCH) regardless of whether simultaneous transmission of the PUCCH and a physical uplink shared channel (PUSCH) is configured or not.

Abstract: The disclosure of the present specification provides a method in which a narrowband-Internet of things (NB-IoT) device transmits an uplink channel. The method comprises: determining an uplink subcarrier spacing for transmitting an uplink channel; determining the length of a subframe on the basis of the subcarrier spacing; and transmitting the uplink channel in a subframe having the determined length. The last part of the subframe may be excluded from the transmission of the uplink channel.

Abstract: The present description provides a method for transmitting a scheduling request (SR) in a low-capability (LC) or low-cost (LC) device. The method can comprise a step for receiving an upper layer signal comprising an SR subframe offset and an SR transmission period. The upper layer signal can further comprise information about the number of repetitions. Also, the method can comprise the steps of: determining, on the basis of the SR transmission period and SR subframe offset, a subframe on which the SR is to be transmitted; determining the number of repeated transmissions of the SR on the basis of the information; and transmitting the SR on the determined subframe. The SR can repeatedly be transmitted on a plurality of subframes that begin from the determined subframe.
