Abstract: A method and a device for transmitting reference signals in a wireless communication system are disclosed. For these, a sequence is acquired to be used for the reference signals, and the reference signals are transmitted through subframes comprising a first type subframe and a second type subframe. Here, the first type subframe includes a first number of OFDM symbols and the second type subframe includes a second number of OFDM symbols. And, a first position of OFDM symbol for transmitting the reference signals at the first type subframe is the same as a second position of OFDM symbol for transmitting the reference signals at the second type subframe.

Abstract: A method and apparatus for allocating resources to a low cost user equipment (UE) in a wireless communication system is provided. A base station (BS) allocates at least one sub-bandwidth among a system bandwidth to a low cost UE, and transmits information on the allocated at least one sub-bandwidth to the low cost UE. The at least one sub-bandwidth may include a set of resource physical resource blocks (PRBs) that the low cost UE can access at a given subframe.

Abstract: The present invention relates to, in a wireless access system supporting an unlicensed band, methods for configuring and scheduling a partial subframe (pSF) and devices for supporting same. A method for receiving data through a cell (U cell) configured in an unlicensed band in a wireless access system for supporting an unlicensed band comprises the steps of: a terminal receiving control information from a base station through a primary cell (P cell) which is configured in a licensed band; and the terminal receiving, on the basis of the control information, downlink data from the base station through an unlicensed band cell (U cell) which is configured in an unlicensed band, wherein, if cross-carrier scheduling is configured in the terminal, the terminal not anticipating, as the subframe for receiving the downlink data, a partial subframe (pSF) which is transmitted in a state of having the first part of symbol emptied, wherein the pSF is configured to be smaller than one subframe.
