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 subframes, 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 is presented for a communication apparatus to transmit an uplink signal in a wireless communication system. The communication apparatus receives a control channel signal including resource allocation information indicating a plurality of non-consecutive resource sets, each of the resource sets including a single resource block group (RBG) or at least two consecutive RBGs. The communication apparatus transmits the uplink signal using the RBGs of the plurality of non-consecutive resource sets indicated by the resource allocation information of the control channel signal. The resource allocation information uses a combinatorial index corresponding to at least four different indices, s0, s1, s2 and s3, to indicate the two or more non-consecutive resource sets, whereby s0 and s1−1 indicate a starting RBG and an ending RBG, respectively, of a first resource set, or s2 and s3−1 indicate a starting RBG and an ending RBG, respectively, of a second resource set.
