5G Air Interface

Different application requirements for air interface technology is complex and diverse, a unified new air interface with flexibility and adaptability is proposed to meet these requirements. New air interface consists of building blocks and configuration mechanisms such as adaptive waveform, adaptive protocols, adaptive frame structure, adaptive coding and modulation family and adaptive multiple access schemes. With these blocks and mechanisms, the air interface is able to accommodate the future wide variety of user services, spectrum bands and traffic levels.
