Methods for enhancing scheduling efficiency in HARQ-ACK disabled IoT NTN - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240340888 titled 'Methods for enhancing scheduling efficiency in HARQ-ACK disabled IoT NTN

Simplified Explanation: The patent application describes a system and method to increase the peak data rate achieved in HARQ feedback-disabled user equipment in a narrowband Internet of Things (NB-IoT) non-terrestrial network system.

  • The system involves NB-IoT devices connected to a gNodeB through a satellite, where downlink control information (DCI) N0 is received at the UE.
  • The UE checks a Hybrid Automatic Repeat reQuest (HARQ) process number field to confirm the HARQ feedback is disabled.
  • The system determines the actual number of scheduled transmission blocks (TB) in an uplink based on a new data indicator field and a number of scheduled TBs for unicast field in the DCI N0.
  • The actual number of scheduled TBs can be greater than two without adding new bits to the DCI N0.

Key Features and Innovation:

  • Increasing peak data rate in HARQ feedback-disabled UE in NB-IoT non-terrestrial network system.
  • Utilizing new data indicator field and scheduled TBs for unicast field in DCI N0.
  • Achieving higher data rates without adding new bits to DCI N0.

Potential Applications:

  • Enhancing data transmission efficiency in NB-IoT networks.
  • Improving connectivity and data rates for IoT devices in non-terrestrial networks.

Problems Solved:

  • Addressing limitations in peak data rates for HARQ feedback-disabled UEs.
  • Optimizing data transmission in narrowband IoT networks.

Benefits:

  • Increased peak data rates for UEs.
  • Enhanced data transmission efficiency.
  • Improved connectivity for IoT devices.

Commercial Applications: The technology can be applied in satellite communication systems, IoT networks, and other non-terrestrial communication setups to boost data rates and improve connectivity for various applications.

Questions about the Technology: 1. How does the system determine the actual number of scheduled transmission blocks in the uplink? 2. What are the key advantages of increasing peak data rates in HARQ feedback-disabled UEs in NB-IoT networks?


Original Abstract Submitted

a system and method is provided for increasing a peak data rate achieved in harq feedback-disabled user equipment (ue) in a narrow band internet of things (nb-iot) non-terrestrial network (ntn) system where nb-iot devices are connected to the gnodeb (gnb) through a satellite where a downlink control information (dci) n0 is received at the ue and the ue checks a hybrid automatic repeat request (harq) process number field to confirm the harq feedback is disabled, where the system determines an actual number of scheduled transmission blocks (tb) in an uplink based on a new data indicator field and a number of scheduled tbs for unicast field in the dci n0. the actual number of scheduled tbs being greater than two without adding new bits to the dci n0.
