==HARQ FEEDBACK CODEBOOK FOR MULTICAST AND UNICAST - A simplified explanation of the abstract==


This abstract first appeared for US patent application 18553741 titled 'HARQ FEEDBACK CODEBOOK FOR MULTICAST AND UNICAST

==Simplified Explanation==

The abstract describes a wireless device that uses a codebook to provide feedback to a network node based on different types of downlink data. The codebook is determined by combining timing sets for multicast and unicast data, and the feedback bits are determined based on resource allocation lists for each type of data.

* Wireless device obtains a codebook based on timing sets for multicast and unicast data feedback.
* Number of downlink slots in the codebook is determined by combining the timing sets.
* Feedback is transmitted to a network node using the codebook.
* Feedback bits for each downlink slot are determined based on resource allocation lists for multicast and unicast data.

== Potential Applications ==
This technology can be applied in:
* Wireless communication systems
* Multicast and unicast data transmission
* Network optimization

== Problems Solved ==
This technology helps in:
* Efficient feedback transmission
* Resource allocation for different types of data
* Improving network performance

== Benefits ==
The benefits of this technology include:
* Enhanced communication reliability
* Optimal resource utilization
* Improved network efficiency

== Potential Commercial Applications ==
This technology can be used in:
* 5G networks
* IoT devices
* Telecommunication infrastructure

== Possible Prior Art ==
One possible prior art could be the use of codebooks for feedback transmission in wireless communication systems.

== Unanswered Questions ==
=== How does this technology impact battery life in wireless devices? ===
The abstract does not mention the impact of this technology on the battery life of wireless devices. It would be interesting to know if the increased feedback transmission affects the power consumption.

=== Are there any limitations to the number of feedback bits that can be transmitted? ===
The abstract does not specify any limitations on the number of feedback bits that can be transmitted. It would be important to understand if there are any restrictions on the amount of feedback that can be provided.


==Original Abstract Submitted==

A wireless device () obtains a codebook that is based on a first downlink data to uplink feedback timing set () for feedback associated with multicast downlink data and a second downlink data to uplink feedback timing set () for feedback associated with unicast downlink data. A number of downlink slots associated with the codebook is determined based on a union of the first set and the second set. The wireless device transmits feedback to a network node () based on the codebook. A number of feedback bits () in the codebook for a downlink slot associated with the codebook is determined based on a union of a first Time Domain Resource Allocation, TDRA, list and a second TDRA list. The first list indicates possible allocations of symbols for a downlink shared channel for multicast. The second list indicates possible allocations of symbols for a downlink shared channel for unicast.
