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 20240163886 titled 'Hybrid Automatic Repeat Request (HARQ) Based on Codeblock Groups in New Radio Systems

Simplified Explanation

The abstract describes a patent application related to communication methods between user equipment (UE) and generation node-b (gnb) in a wireless network.

• The UE receives a physical downlink control channel (PDCCH) that schedules a physical downlink shared channel (PDSCH) on a component carrier (CC) of multiple CCs.
• The PDCCH includes 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 indicates the total number of CCs and slots for the HARQ-ACK feedback.
• The UE encodes the HARQ-ACK feedback to include a bit indicating successful decoding of the PDSCH.
• The size of the HARQ-ACK feedback is based on the total DAI, and the position of the bit is based on the counter DAI.

Potential Applications

This technology can be applied in:

• 5G and beyond wireless communication systems
• Internet of Things (IoT) devices

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.
