Abstract: In the present invention, a part of a first demodulation reference signal sequence generated on the basis of a basic subcarrier interval (hereinafter, a first subcarrier interval) is used for a second subcarrier interval which is K times the first subcarrier interval. Values selected one for every K from among values constituting the first demodulation reference signal sequence may be used as values constituting a second demodulation reference signal sequence for the second subcarrier interval.

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: The present invention discloses a method of transmitting an SSS (secondary synchronization signal), which is transmitted by a base station, in a wireless communication system. The method includes the steps of determining a first shift based on a first and a second cell identifiers for identifying a cell, and determining a second shift index based on the first cell identifier and transmitting the SSS using a first sequence which is generated based on the first shift index and a second sequence which is generated based on the second shift index. In this case, the first shift index can be determined as K times a value determined based on the first and second cell identifiers, where K is an integer equal to or greater than 3.
