Title:
METHOD AND DEVICE FOR LOW LATENCY COMMUNICATION IN COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2019/199051
Kind Code:
A1
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.
