Highlights and Novelties
1- Firstly, a new achievable rate formula is discussed to characterize the decoding error probability for haptic users.

2- Secondly, haptic traffic forecasting mechanisms are reviewed to reduce uplink transmission due to a grant-based scheduling mechanism in LTE.

3- Thirdly, radio resource allocation and collaborative communications are discussed to achieve the ultra-low latency and ultra-high reliable requirements.

4 - Finally, the research challenges are provided.

 

Manuscript Abstract
Tactile Internet (TI) is an evolution of the Internet of Thing (IoT). It enables haptic communications in critical-mission applications such as industrial automation, autonomous driving, healthcare, etc. Quality of Service (QoS) requirements of haptic communications are stringent in end-to-end (E2E) latency within 1 ms and reliability up to 99.9999999%. In addition, haptic data is extremely bursty. It is hard to effectively allocate radio resource to serve haptic service. Haptic traffic forecasting mechanisms can deal with the problem with supports of machine learning (ML) models. Moreover, haptic communication comprises of collaborative communications. It includes collaboration among multi-haptic users and multi-modal data. Therefore, in this paper, we aim to review the state-of-the-art and research challenges of haptic traffic forecasting, radio resource allocation, collaborative communications for the Tactile Internet-enabled haptic communications. Firstly, a new achievable rate formula is discussed to characterize the decoding error probability for haptic users. Secondly, haptic traffic forecasting mechanisms are reviewed to reduce uplink transmission due to a grant-based scheduling mechanism in LTE. Thirdly, radio resource allocation and collaborative communications are discussed to achieve the ultra-low latency and ultra-high reliable requirements. Finally, research challenges are provided
