Abstract: A learning method of distributed artificial intelligence is disclosed. The method is comprising: updating, by the local device, parameters of a corresponding local model by training the local model based on a corresponding local dataset; generating, by the local device, compressed gradient information by compressing gradients of the parameter of the local model; transmitting, by the local device, the compressed gradient information to a parameter server; reconstructing, by a parameter server, gradients of the parameters of the local model based on the compressed gradient information received from the local device; and updating, by the parameter server, parameters of a global model based on the reconstructed gradients of the parameters of the local model.

Abstract: Disclosed are a method and an apparatus for enhanced conditional handover (CHO). An operation method of a base station may comprise: receiving a measurement report message from a terminal; transmitting a CHO request message to one or more candidate target cells; receiving a CHO request ACK message from the one or more candidate target cells; and transmitting an RRC reconfiguration message including CHO status report configuration information to the terminal, wherein the CHO status report configuration information requests transmission of information for determining a target cell to which terminal is likely to be handed over among the one or more candidate target cells.

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.
