Senior Engineer (PI)/Engineer (PI)/Engineering Associate (PI), Wireless Sys Design (5G Base Station)

Ref. ID:  CEO/CT/BSOL/1296


The Hong Kong Applied Science and Technology Research Institute (ASTRI) was founded by the Government of the Hong Kong Special Administrative Region in 2000 with the mission of enhancing Hong Kong’s competitiveness through applied research. ASTRI’s core R&D competence in various areas is grouped under four Technology Divisions: Communications Technologies, Trust and AI Technologies, Integrated Circuits and Systems, and IoT Sensing and AI Technologies.


It is applied across six core areas which are Smart City, Financial Technologies, New Industrialisation and Intelligent Manufacturing, Digital Health, Application Specific Integrated Circuits, and Metaverse.


Over the years, ASTRI has nurtured a pool of research, I&T talents and received numerous international awards for its pioneering innovations as well as outstanding business and community contributions. To date, ASTRI has transferred almost 1400 technologies to the industries and been granted more than 1000 patents in the Mainland, the US, and other countries.


To support our constant endeavour to position Hong Kong as a world-class smart city and an international hub of innovation and technology, we are seeking qualified professionals to fill the following position(s):


Projects Description:
The project team plans to carry out studies on 3GPP Release 17 technologies related to the enhancements of time synchronization and quality of service (QoS), including 1) 5G base station time synchronization accuracy; 2) 5G enhancements to support survival time requirements.


The project team will develop algorithms on mitigation mechanisms for large propagation delays in 5G Non-Terrestrial Networks (NTN):

  • (a) Reference timing advance values broadcast by base station and timing advance values of terminals;
  • (b) Random access channel occasions for multiple terminals; and
  • (c) Scheduling offset value of uplink transmission. The algorithms are compliant with 3GPP standard specifications.
