Tóm tắt

Trong các hệ thống 5G và tương lai, giao tiếp siêu tin cậy và độ trễ thấp (URLLC) được xem là yếu tố chủ chốt để hỗ trợ các dịch vụ quan trọng đa dạng, chẳng hạn như tự động hóa công nghiệp, chăm sóc sức khỏe từ xa và giao thông thông minh. Tuy nhiên, hai yêu cầu nghiêm ngặt của URLLC: độ trễ cực thấp và độ tin cậy cực cao đã đặt ra những thách thức lớn trong thiết kế hệ thống. Trong bài viết này, các khái niệm cơ bản và các ứng dụng tiềm năng của URLLC sẽ được giới thiệu trước. Sau đó, các nghiên cứu tiên tiến về URLLC ở lớp vật lý, lớp liên kết và lớp mạng sẽ được tổng quan. Ngoài ra, một số chủ đề nghiên cứu tiềm năng và thách thức cũng sẽ được xác định.
