Hybrid Automatic Repeat Request (HARQ) Based on Codeblock Groups in New Radio Systems - A simplified explanation of the abstract
This abstract first appeared for US patent application 18404410 titled 'Hybrid Automatic Repeat Request (HARQ) Based on Codeblock Groups in New Radio Systems
Simplified Explanation
The abstract describes embodiments of a communication system involving User Equipment (UE) and Generation Node-B (gNB) for scheduling data transmission on a physical downlink shared channel.
- UE receives a physical downlink control channel (PDCCH) that schedules a physical downlink shared channel (PDSCH) on a component carrier (CC) of multiple CCs.
- PDCCH includes a total downlink assignment index (DAI) and a counter DAI for HARQ-ACK feedback of the PDSCH.
- Total DAI indicates the number of CCs and slots for the HARQ-ACK feedback.
- UE encodes the HARQ-ACK feedback to indicate successful decoding of the PDSCH.
- Size and position of the HARQ-ACK feedback are determined based on the total DAI and counter DAI.
Potential Applications
- 5G communication systems
- Wireless networks
Problems Solved
- Efficient scheduling of data transmission
- Reliable feedback mechanism for data decoding
Benefits
- Improved data transmission efficiency
- Enhanced reliability in communication systems
Potential Commercial Applications
Optimized data transmission in:
- Telecommunications
- Internet of Things (IoT) devices
Possible Prior Art
Prior art may include:
- Previous methods of scheduling data transmission in wireless communication systems
- Existing feedback mechanisms for data decoding in communication networks

Original Abstract Submitted
Embodiments of a User Equipment (UE), Generation Node-B (gNB) and methods of communication are disclosed herein. The UE may receive a physical downlink control channel (PDCCH) that schedules a physical downlink shared channel (PDSCH) in a slot, and on a component carrier (CC) of a plurality of CCs. The PDCCH may include a total downlink assignment index (DAI) and a counter DAI for hybrid automatic repeat request acknowledgement (HARQ-ACK) feedback of the PDSCH. The total DAI may indicate a total number of pairs of CCs and slots for the HARQ-ACK feedback. The UE may encode the HARQ-ACK feedback to include a bit that indicates whether the PDSCH is successfully decoded. A size of the HARQ-ACK feedback may be based on the total DAI, and a position of the bit may be based on the counter DAI.
