Abstract: Provided are a method and device for transmitting a scheduling request in a wireless communication system. In detail, a terminal receives, from a base station, resource allocation information for indicating a semi-persistent scheduling request and a scheduling request resource. The terminal receives, from the baste station, a first indicator for indicating whether the semi-persistent scheduling resource is activated and a second indicator for indicating whether the scheduling request resource is activated. The terminal determines whether the scheduling request can be transmitted on the basis of the first indicator and the second indicator. The terminal transmits the scheduling request to the base station via the scheduling request resource indicated by the resource allocation information.

Abstract: Provided are a method and an apparatus for obtaining downlink synchronization in a wireless communication system. The wireless communication system that is proposed has an environment in which the resource location of a downlink synchronization signal changes due to the application of multiple numerology. Particularly, a terminal receives synchronization signal information from a base station. The synchronization signal information includes candidate resources from which synchronization signals with respect to a tracking area can be transmitted, and the order of detecting the synchronization signals from the candidate resource win respect to the tracking area. The terminal detects the synchronization signal on the basis of the synchronization signal information.

Abstract: Provided are a method and an apparatus for transmitting uplink data in a wireless communication system. Specifically, a first terminal transmits a random access preamble for requesting a connectionless transmission. The first terminal receives a random access response comprising scheduling information of the uplink data. The first terminal transmits the uplink data, a reference signal selected by the terminal and terminal identification information of the terminal from a first overlapping resource utilized by a second terminal. The first terminal receives, as a response for the uplink data, a response signal comprising a terminal identification information field containing terminal identification information corresponding to each reference signal.

Abstract: A method and 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 herein suggests a method for increasing the receipt reliability of a terminal with respect to a multiplex transmission activation indicator indicating the start of multiplex transmission. Particularly, a terminal checks the receipt of a multiplex transmission activation indicator transmitted, from a first base station, for every predetermined subframe. If the terminal succeeds in receiving the multiplex transmission activation indicator, an ACK signal associated with the multiplex transmission activation indicator is transmitted to the first base station. Here, the multiplex transmission activation indicator indicates that the first base station and a second base station are capable of transmitting the same data for a predetermined time together.

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: Provided are a method and a device for transmitting data in a wireless communication system. More particularly, a terminal transmits a first transmission preamble and a second transmission preamble so as to estimate an uplink channel. If a common temporary identifier is assigned to the first and second transmission preambles, a common response message for the first and second transmission preambles is received. If temporary identifiers that are different from each other are respectively assigned to the first and second transmission preambles, respective individual response messages for the first and second transmission preambles are received. Data is transmitted by means of an estimated uplink channel. The first transmission preamble is transmitted in a plurality of resource regions, and the second transmission preamble is transmitted in one resource region.
