Abstract: Embodiments of the present invention relate to a wireless access system supporting a non-licensed band and, more particularly, to methods for transmitting or receiving sub-frame length information indicating the lengths of current and next sub-frames, and apparatuses for supporting the same. As an embodiment of the present invention, a method for receiving sub-frame (SF) length information in a wireless access system supporting a non-licensed band may comprise the steps of: receiving a signal including first SF length information indicating the lengths of one or more of a current SF and a next SF in sub-frame number n−1 (SF # n−1); and receiving one or more of a downlink physical channel and a downlink signal in the SF # n−1 on the basis of the first SF length information. Here, the first SF length information may indicate that the current SF or the next SF is the end SF of a downlink transmission burst in the non-licensed band.

Abstract: A method for and apparatus for supporting scheduling groups based on devices characteristics in a wireless communication system is provided. A wireless device receives a group identification(ID) to monitor a physical downlink control channel (PDCCH) for Machine Type Communication (MTC), receives the PDCCH with the group ID at a predetermined subframe, and configures a physical downlink shared chancel (PDSCH) and a physical uplink shared chancel (PUSCH) shared with MTC UEs by the PDCCH of grant. And, more efficient and accurate scheduling with lower complexity and reduction of control overhead, for multi-UEs is provided in this invention.
