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.

Abstract: The present invention relates to a wireless communication system. More specifically, the present invention relates to a method and a device for performing reflective Quality of Service (QoS) in wireless communication system, the method comprising: receiving a DL PDU with a QoS flow ID via a DL DRB identified by a first DRB ID from a network; determining whether or not to update UL QoS flow to DRB mapping rule according to a value of the QoS flow ID; and transmitting UL data via a UL DRB mapped to QoS flow ID of the UL data based on the UL QoS flow to DRB mapping rule, wherein if the QoS flow ID is not a specific value but a first QoS flow ID, the UL QoS flow to DRB mapping rule is updated such that a UL DRB mapped to the first QoS flow ID is changed to a UL DRB identified by the first DRB ID, and wherein if the QoS flow ID is the specific value, the UE doesn't update the UL QoS flow to DRB mapping rule.

Abstract: A method and a device for communicating using a wireless frame in a TDD-based wireless communication system are provided. Specifically, a first indicator indicating a first DL and UL subframe configuration and a second indicator indicating a second DL and UL subframe configuration for a wireless frame are received. Information on a third DL and UL subframe configuration for the wireless frame, determined by the first and second indicators, is received. A portion of the third DL and UL subframe configuration is determined by the second indicator, and the remaining portion of the third DL and UL subframe configuration is determined by the first indicator. According to the third DL and UL subframe configuration, a downlink signal is received and an uplink signal is transmitted.

Abstract: Disclosed is a method of transmitting signals by a transmitting side device having multiple antennas. In this method, the transmitting side device spatially modulates information to be transmitted, where the information is spatially modulated to be represented based on which antennas among the N antennas are selected to be used for transmission. And, the transmitting side device transmits the spatially modulated information through the selected antennas. Here, the number of the selected antennas for transmitting one transmission information unit (hereinafter, ‘M’ where M≤N) is plural. And, different sequence of the selected antennas represents different information to be transmitted.
