Abstract: Provided are a method and an apparatus for transmitting a maximum stratum level in a wireless communication system. An evolved NodeB (eNB) or a home eNB (HeNB) having a global positioning system (GPS) constitutes a maximum stratum level indicating a maximum value of a hop capable of supporting radio interface based synchronization (RIBS) and transmits the constituted maximum stratum level to a small cell. Meanwhile, the small cell determines whether a stratum level is greater than the maximum stratum level, and transmits the maximum stratum level to the eNB or the HeNB having the GPS when the stratum level is greater than the maximum stratum level.

Abstract: A method and apparatus for determining a length of a physical downlink shared channel (PDSCH) (or, a partial subframe) in a wireless communication system is provided. A user equipment (UE) detects at least one of starting orthogonal frequency division multiplexing (OFDM) symbol or ending OFDM symbol of a PDSCH in an unlicensed carrier, and determines the length of the PDSCH in the unlicensed carrier based on the at least one of the starting OFDM symbol or the ending OFDM symbol of the PDSCH in the unlicensed carrier. The UE may detect the at least one of starting OFDM symbol or ending OFDM symbol based on a physical downlink control channel (PDCCH) or a reference signal (RS) pattern.

Abstract: A method and apparatus for transmitting/receiving a downlink channel in a wireless communication system are provided. A downlink control channel and a downlink data channel corresponding to the downlink control channel are transmitted/received within a transmission time interval (TTI). A reference signal (RS) of an antenna port used for transmission of both the downlink control channel and the downlink data channel is transmitted/received on an OFDM symbol with the downlink control channel, and an RS of an antenna port used only for transmission of the downlink data channel is transmitted in the remaining OFDM symbol(s) of the TTI.

Abstract: The disclosure of the present specification provides a method for receiving a physical downlink shared channel (PDSCH) on a low-capability (LC) or low-cost (LC) device. The method may comprise the steps of: receiving repetition of a downlink control channel in the case that the LC device is set to coverage enhancement (CE); determining a last subframe where the reception is terminated; and determining a start subframe for receiving the repetition of the PDSCH on the basis of the last subframe. The reception of the PDSCH starts at the k-th effective subframe after subframe n, and the subframe n may be the last subframe where the reception of the downlink control channel is terminated. K is greater than or equal to 2, and the effective subframe may be predetermined.
