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 #n; 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 (HARQ) 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.

Abstract: An operation method of a terminal includes receiving configuration information from a serving base station; measuring channel states of the serving base station and a target base station; when a difference between received signal strengths of the serving base station and the target base station is not less than a handover preparation offset, determining that a handover preparation event has occurred and transmitting a measurement report message to the serving base station; and when the difference is equal to or greater than a handover execution offset, determining that a handover execution event has occurred and transmitting a handover indication message informing of execution of a handover to the target base station. The channel state is normal state, abnormal state, or RLF state, and the configuration information indicates a different handover preparation offset and a different handover execution event according to the channel state.

Abstract: Disclosed is an operation method of a terminal in a mobile communication system. The operation method may comprise starting a T310 timer when a physical layer out-of-synchronization occurs in a PDCCH transmitted from a first base station; confirming that an RLF occurs when the PDCCH does not transition to a physical layer in-sync state until the T310 timer expires; performing re-establishment of PDCP layers and RLC layers for all radio bearers except an SRB0; suspending all the radio bearers except the SRB0; performing RRC connection re-establishment with a second base station selected through cell selection; and resuming all the radio bearers when the RRC connection re-establishment with the second base station succeeds.

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.
