Results in brief

Flexible Channel Coding for 6G Short Packet Communication

The upcoming sixth-generation (6G) mobile networks are poised to tackle global challenges like urbanization and the digital divide by aligning with the UN Sustainable Development Goals (SDGs), aiming to empower individuals, sense the environment, and strengthen global ecosystems by 2030. Achieving this demands capabilities far beyond current 5G standards, particularly for critical use cases like wireless factory automation and autonomous driving, which require ultra-high reliability, ultra-low latency, high-resolution localisation, and precise inter-device synchronicity. A key hurdle is the need for highly flexible and efficient short packet communications, as current channel coding and decoding techniques are insufficient for the short to moderate blocklengths vital for 6G. This project focused on developing novel rateless coding schemes and decoding algorithms specifically optimised for finite blocklengths, offering flexibility in code rates and blocklengths, and featuring low-complexity decoding to mitigate latency. The main objectives of this project are as follows: • Objective 1: Develop flexible and granular rateless codes for finite blocklength channels. • Objective 2: Reduce decoding complexity of the designed rateless codes. • Objective 3: Minimise decoding iterations through novel approaches.

Project objective

The emerging sixth-generation (6G) of mobile networks will be a key part of the solution to the constantly increasing problem of urbanization and the digital divide. 6G has aligned its focus to the United Nations sustainable development goals (SDGs) and aims by 2030 to achieve the following targets: a) empower people by providing services and solutions to individuals and society; b) sense the environment by performing extensive hyper-local measurements and c) strengthen the world by reinforcing the ecosystem according to the SDGs. Key 6G use cases such as wireless factory automation and autonomous driving will require ultra-high reliability and ultra-low latency, high-resolution localization, and high-accuracy inter-device synchronicity. These requirements are well beyond the capabilities of existing mobile standards, including the fifth-generation (5G) mobile. Short packet communications play a key role in meeting the low latency requirements of many 6G applications. Despite recent progress, the design of effective channel coding and decoding techniques for short packet communications is still far from sufficiency. 6G communication systems require flexibility in the blocklength and coding rates. Short and moderate blocklength codes (approx. from 100 bits to a few thousand bits) with close-to-optimal performance are required for 6G. A promising solution is rateless codes carefully optimized for short blocklength and able to provide flexibility in code rates, blocklength, and decoding complexity. The main objective of this project is to develop new rateless coding schemes and decoding algorithms, to address the flexibility and bit-granularity for finite blocklength channel codes, and to design low-complexity decoding algorithms to address the latency issue in 6G short packet communications. It is expected that our results can largely improve the performance of 6G networks in terms of latency, reliability, flexibility and complexity.
