Title:
SYSTEM AND METHOD FOR TRANSMISSION REDUNDANCY IN WIRELESS COMMUNICATIONS
Document Type and Number:
WIPO Patent Application WO/2020/098776
Kind Code:
A1
Abstract:
The present invention provides a system and method for ultra reliable low latency communication (URLLC) which can be achieved by redundant transmission with two or more links at one or more RAN nodes. In order to achieve URLLC communication, methods supporting the PDCP packet duplication and/or higher layer packet duplication are applied to various RAN architectures such as CA architecture, DC based architecture with one connection to the core network (CN), DC based architecture with two or more connections to the CN, CA and DC combined architecture, and CU/DU split architecture.
