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.

Abstract: The disclosure of the present specification provides a method for receiving a downlink control channel in a machine type communication (MTC) device configured to operate in only a partial band of the system band of a cell. The method may comprise the steps of: considering the number of physical resource block (PRB) pairs, to which a downlink control channel can be mapped, to be one of 2, 4, and 8; when the considered number of PRB pairs is greater than the number of PRB pairs to which the downlink control channel is actually mapped, determining that the downlink control channel is not included in PRB pairs except the number of PRB pairs to which the downlink control channel is actually mapped; and receiving the downlink control channel in only as many PRB pairs as the number of PRB pairs to which the downlink control channel is actually mapped, on the basis of the determination.

Abstract: A disclosure of the present specification provides a method for transmitting an uplink channel and a demodulation reference signal (DMRS) by a machine type communication (MTC) device. The method may comprise the steps of: determining a frequency resource area for transmitting an uplink channel so as to have a size equal to or smaller than the size of a physical resource block (PRB) including 12 subcarriers; generating a DMRS sequence for some sub-carriers among the 12 subcarriers when the frequency resource area for transmitting the uplink channel is determined to have a size smaller than the size of the PRB including the 12 subcarriers; and transmitting the uplink channel and the DMRS on the some subcarriers in the PRB.

Abstract: Information indicating one of possible PDSCH start subframes may be provided to the UE via the PDCCH. The PDSCH corresponding to the PDCCH may be transmitted/received starting from the indicated subframe. The possible PDSCH start subframes may be determined based on the ratio of the maximum number of PDCCH repetitions in the PDCCH search space and may be determined based on the ratio of the number of times related to the PDSCH repetition after the PDCCH search space.

Abstract: The present specification provides a method for obtaining downlink synchronization in a machine type communication (MTC) apparatus. The MTC apparatus may comprise the steps of: receiving an MTC-dedicated synchronization signal from a base station on the subframe before a subframe which attempts to receive a paging message; obtaining a downlink synchronization of the base station through the synchronization signal; and after obtaining the downlink synchronization, attempting to receive the paging message. Here, the MTC-dedicated synchronization signal may be received on the same sub-band as a sub-band on which the paging message is received, from among the entire system band of the base station.

Abstract: One downlink control information DCI may be divided into first DCI and second DCI to be transmitted/received. The first DCI may be transmitted/received within a control region of a first TTI of a first time length. The first DCI may include information about the second DCI in a second TTI of a second time length shorter than the first time length. The first DCI may be transmitted/received using first decoding candidates for transmission of the first DCI among decoding candidates in the search space in the control region of the first TTI. The decoding candidates other than the first decoding candidate among the decoding candidates in the search space may be used for transmission/reception of legacy DCI.
