Abstract: A method for transmitting and receiving a signal by a terminal in a wireless communication system is disclosed in the present invention. More particularly, the method comprises the steps of: receiving an indicator for changing the usage of a specific subframe corresponding to a sub-component carrier from a network; determining whether near-end crosstalk between the sub-component carrier and another component carrier occurs if the usage of the subframe is changed according to the indicator; and transmitting and receiving a signal to and from the network through the sub-component carrier according to the changed usage if it is determined that the near-end crosstalk does not occur.

Abstract: A method for requesting an uplink scheduling is provided. In the case that there is an SR PUCCH resource established on a secondary cell, not an SR PUCCH resource established on a primary cell, and a special secondary cell is in a state of de-activation at the time of sending an uplink scheduling request, the uplink scheduling request is stopped and a random access procedure is initiated. If the uplink scheduling request can be sent on a plurality of cells at the same point of time, that is, if there are a plurality of uplink resources available for the uplink scheduling request at the same point of time, the uplink scheduling request is sent only on one of the plurality of cells (and using only one uplink resource).

Abstract: The present invention relates to a wireless access system that supports unlicensed bands, and relates to a method for reporting channel state information when a partial subframe (pSF) is formed. A method for user equipment (UE) reporting channel state information (CSI) in a wireless access system that supports unlicensed bands according to an embodiment of the present invention may comprise the steps of: receiving a downlink burst configured to an unlicensed band cell (U cell) supporting unlicensed bands as far as a certain subframe; measuring CSI with respect to the downlink burst; and reporting the measured CSI to a base station. In this regard, if a pSF is included in the downlink burst, the UE does not consider the pSF to be a valid downlink subframe for CSI measurement, and the pSF may be formed to have a smaller size than a general subframe.
