US 12,587,321 B2 · UE configured for enhanced type 3 HARQ-ACK codebook triggering by DCI format

Abstract

An apparatus and system are described to provide enhanced Type-3 HARQ-ACK codebook transmission are described. A gNB configures a UE for hybrid automatic repeat request (HARQ)-acknowledgment (ACK) (HARQ-ACK) retransmission using the enhanced Type-3 codebook using radio resource control signaling. The enhanced Type-3 codebook is triggered by downlink control information (DCI) format 1_1 or 1_2 and transmitted using a physical uplink control channel (PUCCH) or a physical uplink shared channel (PUSCH). Information in the DCI includes: whether to use configured, activated, or indicated carriers, cell indexes for the carriers, whether to use all HARQ processes, use only semi-persistent scheduling (SPS) processes, or use only non-SPS processes, whether to use all priority HARQ processes, use only high priority HARQ processes, or use only low priority HARQ processes, and HARQ process range.

Dependent claims

An apparatus for a user equipment (UE) configured for operation in a fifth-generation new radio (5G NR) network, the apparatus comprising:

processing circuitry;
and memory, wherein the processing circuitry is configured to:
decode radio resource control (RRC) configuration information received from a gNodeB (gNB) to enable enhanced Type 3 HARQ-ACK codebook triggering by a downlink control information (DCI) format;
decode the DCI format received from the gNB requesting a Type-3 HARQ-ACK codebook report;
determine a PDSCH HARQ-ACK Enhanced Type 3 Index value from an enhanced Type 3 codebook indicator field in the DCI format when the DCI format schedules a physical downlink shared channel (PDSCH) reception;
determine the PDSCH HARQ-ACK Enhanced Type 3 Index value from a value of a modulation and coding scheme (MCS) field of the DCI format when the DCI format does not schedule the PDSCH reception and when the DCI format does not include the enhanced Type 3 codebook indicator field;
and determine the enhanced Type 3 HARQ-ACK codebook based on the PDSCH HARQ-ACK Enhanced Type 3 Index value for transmission to the gNB.
