Abstract: An operation method of a terminal in a communication system includes receiving bandwidth part (BWP) change information from a base station in a BWP i; changing an operation BWP of the terminal from the BWP i to a BWP j even when a transmission and reception procedure of first data in the BWP i is not completed at a BWP changing point indicated by the BWP change information; and performing a data transmission and reception procedure of second data in the BWP j, wherein the BWP i and the BWP j are different BWPs, and i and j are different integers.

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 are a method and a device for low latency communication in a communication system. An operation method of a base station comprises the steps of: transmitting first scheduling information of data units, transmitted through A sections in subframe #n, to a terminal through a first control channel in subframe #n; transmitting the data units to the terminal through the A sections; and transmitting second scheduling information of data unit(s), transmitted through B section(s) in subframe #(n+k) following subframe #n, to the terminal through a second control channel in subframe #(n+k). Therefore, the performance of the communication system can be improved.
