INDICATION OF RETRANSMISSION FOR UPLINK IN NTN SYSTEMS - A simplified explanation of the abstract
This abstract first appeared for US patent application 18555760 titled 'INDICATION OF RETRANSMISSION FOR UPLINK IN NTN SYSTEMS
Abstract: This disclosure presents solutions for a communication system of a non-terrestrial network (NTN) node and a user equipment (UE) to determine, where the NTN node can determine one or more HARQ retransmission schemes for one or more LCHs used by the UE. The HARQ retransmission scheme can be mapped into one, two, or five bits of the DCI signal, depending on the mapping algorithm selected. In some example embodiments, LCHs can be grouped by using similar LCH prioritization or similar HARQ retransmission schemes. HARQ retransmission schemes can be mapped to the LCG. If there remains sufficient data space in the TBS/UL, other LCH can be included into the transmission even though the other LCH utilize different HARQ retransmission schemes. The UE can encode its HARQ transmission using the HARQ retransmission scheme indicated for the LCH the UE is utilizing.
Key Features and Innovation:
- Communication system for NTN node and UE to determine HARQ retransmission schemes for LCHs.
- Mapping of HARQ retransmission schemes into DCI signal bits.
- Grouping of LCHs based on similar prioritization or retransmission schemes.
- Inclusion of additional LCHs in transmission if data space allows, even with different retransmission schemes.
- Encoding of HARQ transmission based on the selected retransmission scheme for the LCH.
Potential Applications: - Satellite communication systems - Non-terrestrial networks - Wireless communication technologies
Problems Solved: - Efficient allocation of HARQ retransmission schemes for LCHs - Optimization of data transmission in non-terrestrial networks - Improved reliability and performance of communication systems
Benefits: - Enhanced data transmission efficiency - Increased reliability in communication systems - Optimal utilization of network resources
