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: Provided are a method and device for transmitting control information in a wireless communication system. In particular, a base station transmits, to a terminal, an RNTI mapped to a downlink terminal group or an uplink terminal group including a terminal, and a terminal ID instructing the terminal in the downlink terminal group or the uplink terminal group. The RNTI and the terminal ID are used to set control information, and the control information includes an identification information field instructing whether scheduling information on the terminal exists, a scheduling information field for the terminals in each terminal group, and a first CRC field. The first CRC field is encoded for the scheduling information field for the terminals in each terminal group. The set control information is transmitted to the terminal.

Abstract: Provided are a method and device for transmitting control information in a wireless communication system. In particular, a downlink resource block group including a downlink resource block in a downlink frequency bandwidth is set, and an uplink resource block group including an uplink resource block in an uplink frequency bandwidth is set. If the downlink frequency bandwidth is smaller than the uplink frequency bandwidth, the downlink resource block group is mapped to the uplink resource block group. The ratio of the number of uplink resource blocks to the number of downlink resource blocks is set so that the number of uplink resource block groups and the number of downlink resource block groups become the same. The uplink and downlink resource block groups are mapped according to the ratio. Control information on the mapping is transmitted through the downlink resource block groups.

Abstract: The present invention relates to a method and apparatus for transmitting and receiving data in a wireless communication system supporting a low latency service. According to the present invention, a terminal transmits a request message for requesting transmission of data to provide the low latency service in an idle state to a base station, and in response to the request message, receives a response message including resource information related to transmission and reception of low latency service data from the base station, thereby when additional data is generated for providing the low latency service for transmitting and receiving the low latency service data, the additional resources may be extended to transmit the additional data.

Abstract: Provided are a method and an apparatus for performing communication in a wireless communication system. Specifically, a control channel element is configured by using a resource element group in the same symbol of a resource block. The resource element group includes a plurality of resource elements in the same symbol. The resource block is transmitted in units of sTTIs which is set to be shorter than TTI. A control channel corresponding to the control channel element, and a data channel scheduled by the control channel are configured. The control channel and the data channel are transmitted in different frequency bands. Data is transmitted through the data channel.
