US 12,193,036 B2 · Time domain resource allocation-based HARQ-ACK feedback generation

Abstract

This disclosure provides systems, devices, apparatus and methods, including computer programs encoded on storage media, for TDRA-based HARQ-ACK feedback generation. In aspects, a UE and a base station may determine that at least one TDRA candidate of a set of TDRA candidates for a PDSCH transmitted from a base station has more than one possible location within a slot. Based on the determination that the at least one TDRA candidate has more than one possible location within the slot, the UE may generate and transmit corresponding HARQ-ACK feedback to the base station, which may decode the HARQ-ACK feedback.

Dependent claims

A method of wireless communication at a user equipment (UE), comprising:

determining that at least one time-domain resource allocation (TDRA) candidate of a set of TDRA candidates for receiving a physical downlink shared channel (PDSCH) has more than one possible location within a slot based on a starting symbol of each of a plurality of physical downlink control channel (PDCCH) monitoring occasions within the slot and a length of the at least one TDRA candidate;
and
transmitting hybrid automatic repeat request (HARQ) acknowledgement (ACK) (HARQ-ACK) feedback based on the at least one TDRA candidate having more than one possible location within the slot.
