Abstract: A method and apparatus for allocating resources for a machine type communication user equipment (MTC UE) in a wireless communication system is provided. A base station indicates a transport block size (TBS) directly, adapts a code rate according to repetition numbers across multiple subframes in a MTC physical downlink shared channel (M-PDSCH) for the MTC UE, and allocates resources for the M-PDSCH by using the indicated transport block size and the adapted code rate. The TBS may be determined based on a modulation and coding scheme (MCS) only.

Abstract: The present invention provides: a base station for repeatedly transmitting a physical downlink control channel (PDCCH) during a first subframe bundle comprising a plurality of subframes, and transmitting a PDSCH related to the PDCCH; and user equipment for receiving the PDCCH and the PDSCH. The PDSCH can be transmitted to the user equipment starting from subframe n+k, which is the kth subframe after the last subframe n−1 in the first subframe bundle, wherein k is an integer bigger than 0. The first subframe bundle may begin from a predetermined or fixed position.

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 data by a transmitter. The method may comprise the steps of: when a transport block (TB) is divided into n data blocks, adding additional information after each of the n data blocks; and adding a cyclic redundancy check (CRC) after the last additional information. Here, the CRC may be generated on the basis of the n data blocks, and the n pieces of additional information added after each of data blocks.

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: A method and apparatus for transmitting a physical HARQ indicator channel (PHICH) in a wireless communication system is provided. A base station (BS) transmits multiple uplink (UL) grants for multiple user equipments (UEs), receives UL data from the multiple UEs, and transmits a group-common PHICH as a response to the UL data received from the multiple UEs.

Abstract: Provided is a method for receiving a downlink control channel in a machine type communication (MTC) device. A method for receiving a downlink control channel can comprise the steps of: receiving first configuration information about an MTC device-operable subband among system bands of a cell; receiving second configuration information, about a subframe, for monitoring a downlink control channel in a cell-specific search space (CSS); and switching from a subband with respect to the first configuration information to a pre-configured cell-common subband and then receiving, in the cell-common subband in a subframe with respect to the second configuration information, a downlink control channel in the CSS and another channel.

Abstract: A system information update notification may be transmitted/received in system information modification period n, updated system information may be transmitted/received in system information modification period (n+1), and the updated system information may be applied from a particular time point after the system information modification period (n+1). The updated system information may include EPDCCH configuration information or start OFDM symbol information which enables a UE to start control/data reception.

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.
