Abstract: Provided are a method and an apparatus for transmitting a scheduling request in a wireless communication system. Particularly, a terminal receives, from a base station, allocation information for an SR resource and allocation information for an SPS resource. The terminal transmits a scheduling request through the SR resource or the SPS resource. The allocation information for the SR resource indicates that the SR resource is allocated to a first period. The allocation information for the SPS resource indicates that the SPS resource is allocated to a second period. When the scheduling request is transmitted through the SPS resource, the scheduling request is not transmitted through a predetermined plurality of subframes including the SPS resource.

Abstract: Here, operation for 3D beam forming is disclosed. UE, receiving reference signals from one or more base stations (eNBs), may report feedback information comprising precoding matrix information to the one or more eNBs. The precoding matrix information indicates a first type precoding matrix for a horizontal direction and a second type precoding matrix for a vertical direction. eNBs may transmit signals, which are precoded based on a third type precoding matrix for beam forming both on the horizontal direction and the vertical direction.

Abstract: A method and a device for receiving a signal in a wireless communication system to which a multiplex transmission technique is applied are provided. The wireless communication system proposed therein suggests a method for performing multiplex transmission when base stations within a network are synchronized. Particularly, a terminal receives, from a first base station, control information for the transmission of an M number of transmission blocks. The control information includes information for allocating multiplex transmission resources available for the first base station and a second base station during a predetermined subframe. The terminal receives the M number of transmission blocks from the first base station and the second base station via the multiplex transmission resources. Here, the M number of transmission blocks receives from the first base station and the M number of transmission blocks received from the second base station are decoded by using the same reference signal.

Abstract: According to the present invention, a first physical downlink control channel (PDCCH) and a second PDCCH can be transmitted to user equipment. A first physical downlink data channel (PDSCH) corresponding to the first PDCCH, and a second PDSCH corresponding to the second PDCCH can be transmitted to the user equipment. When the first PDSCH has a lower decoding priority than the second PDSCH, and the decoding timing of the first PDSCH and the decoding timing of the second PDSCH overlap, the user device may decode the second PDSCH and not the first PDSCH at the decoding timing, and transmit information with respect to the first PDSCH as first ACK/NACK information. As a reply to the first ACK/NACK information, a third PDCCH not having a corresponding PDSCH may be transmitted to the user equipment.

Abstract: A method for transmitting and receiving a packet performed by a first network node in a wireless communication system according to the present disclosure includes receiving a first message in relation to a connection configuration of a specific flow from a user equipment (UE); receiving a second message in relation to a response to the first message from a second network node (e.g., MME/GW); checking whether the first flow ID and the second flow ID are identical; transmitting a UL grant to the UE by considering a processing time of the UE; and receiving a third message from the UE through the UL grant.

Abstract: Provided are a method and an apparatus for transmitting retransmission data using an HARQ in a wireless communication system. Specifically, it is determined whether there is a radio resource for transmitting retransmission data. When the radio resource exists, a DCI format including a retransmission indicator field is configured. The retransmission indicator field indicates whether the retransmission data is general retransmission data or opportune retransmission data. The opportune retransmission data is retransmitted before an ACK/NACK signal for initial transmission data is received. The retransmission data is transmitted through the radio resource according to scheduling of a configured DCI format.
