Abstract: The present invention relates to a wireless communication system. More particularly, the present invention relates to a method and an apparatus for a terminal controlling uplink power in the wireless communication system, comprising the steps of: configuring an uplink subframe (UL SF) of a first set and a UL SF of a second set; receiving a downlink control information (DCI) format including a bitmap for indicating transmit power control (TPC) for a plurality of terminals; and controlling transmit power of an uplink channel by using TPC information on the terminals from the bitmap, wherein the TPC information is used for controlling transmit power of an uplink channel transmitted from the UL SF of the first set when the DCI format comprises a first identifier, and the TPC information is used for controlling transmit power of an uplink channel transmitted from the UL SF of the second set when the DCI format comprises a second identifier.

Abstract: A device attempts to detect an on/off indicator for a plurality of transmission types in a first subframe. The device determines, as a transmission type of a second subframe, a transmission type corresponding to the detected on/off indicator out of the plurality of transmission types. The on/off indicator indicates whether the device expects that transmission according to the determined transmission type will be performed in the second subframe.

Abstract: Provided are method and device for transmitting/receiving control information. A downlink grant can comprise information indicating whether or not an uplink grant is transmitted in the same subframe. If the information indicates that an uplink grant exists, a user equipment attempts detection of the uplink grant in the same subframe in which the downlink grant is received. If not, the user equipment does not attempt detection of the uplink grant. For low latency, the subframe can be shorter than an existing subframe.

Abstract: A method and apparatus for transmitting/receiving a downlink channel in a wireless communication system are provided. A physical downlink control channel (PDCCH) can be transmitted using one or more resource element groups (REGs) among a plurality of REGs in a transmission time interval (TTI). Each of the plurality of REGs occupies 12 consecutive resource elements (REs) belonging to a physical resource block (PRB) along a frequency domain within an orthogonal frequency division multiplexing (OFDM) symbol with or without a reference signal (RS) in the TTI.
