==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
* Mobile broadband networks

== Problems Solved ==
This technology solves issues related to:
* Efficient scheduling of downlink channels
* Reliable transmission of data in wireless 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.
