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

This abstract first appeared for US patent application 20240235875 titled 'HARQ FEEDBACK CODEBOOK FOR MULTICAST AND UNICAST

The abstract describes a patent application for a wireless device that receives a codebook based on timing sets for feedback associated with multicast and unicast downlink data. The device determines the number of downlink slots based on a union of the timing sets and transmits feedback to a network node using the codebook. The codebook also determines the number of feedback bits for each downlink slot based on possible resource allocations for multicast and unicast channels.

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.
