Multi-modality services bring much higher requirements on the network for high data rate, low latency and high reliability communication to enable multi-modality interactions. The IMT-2020 networks and beyond need to support traffic flow coordination of multi-modality communication to ensure extreme user service experience. The objective of this Recommendation is to specify the requirements, framework and potential enhanced functionalities for multi-modality communication, in the context of IMT-2020 and beyond.
