Abstract: Provided is a next-generation wireless local area network (WLAN) frame communication method. The communication method may include modulating a first symbol in a signal field A (SIG-A) of a next-generation WLAN frame using a first modulation method, modulating a second symbol in the SIG-A of the next-generation WLAN frame using a second modulation method, and modulating a short training field (STF) signal of the next-generation WLAN frame in response to a next-generation WLAN mode.

Abstract: A reference signal (RS) transmission system to transmit a channel state information (CSI) RS for extraction of CSI to a relay and a macro terminal is disclosed. The base station transmits information on a sub frame containing the CSI RS to the relay or the macro terminal. The macro terminal and the relay receive the CSI RS using the information on the sub frame. The macro terminal and the relay extract the CSI using the CSI RS and transmit the extracted CSI to the base station.

Abstract: Disclosed are a method and an apparatus for providing low-latency services in a communication system. A downlink communication method may comprise receiving downlink control information (DCI) including resource allocation information from a base station through a control channel of a subframe receiving downlink data from the base station through a data channel of a subframe #n+k indicated by the resource allocation information included in the DCI; and transmitting a first hybrid automatic repeat request (HARM) response for the downlink data to the base station through a control channel of a subframe #n+k+l. Thus, the performance of the communication system can be improved.
