Enhanced hybrid automatic repeat request acknowledgement/negative acknowledgement configurations associated with initial physical downlink control channel communications

An apparatus for wireless communication at a network node, comprising:

• one or more memories;
• and
• one or more processors, the one or more processors, individually or collectively and based at least in part on information stored in the one or more memories, being configured to:
• transmit, to a user equipment (UE), configuration information indicative of a modulation and coding scheme (MCS) reserved for re-transmission, wherein the configuration information is further indicative of an enhanced hybrid automatic repeat request (HARQ) acknowledgement/negative acknowledgement (ACK/NACK) configuration associated with initial physical downlink control channel (PDCCH) communications;
• transmit, to the UE, an initial PDCCH communication;
• transmit, to the UE, a re-transmission of the initial PDCCH communication;
• and
• receive, from the UE in association with the configuration information, enhanced HARQ ACK/NACK information indicative of a failure of the UE to receive the initial PDCCH communication, wherein the enhanced HARQ ACK/NACK information comprises a dedicated bit, added to a HARQ ACK/NACK communication, that indicates the failure of the UE to receive the initial PDCCH communication.

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

• receiving, by the UE and from a network node, configuration information indicative of an enhanced hybrid automatic repeat request (HARQ) acknowledgement/negative acknowledgement (ACK/NACK) configuration associated with initial physical downlink control channel (PDCCH) communications;
• receiving, by the UE and from the network node, a re-transmission of an initial PDCCH communication;
• identifying, by the UE, a failure of the UE to receive the initial PDCCH communication;
• and
• transmitting, by the UE and to the network node in association with the configuration information, enhanced HARQ ACK/NACK information indicative of the failure of the UE to receive the initial PDCCH communication, wherein the enhanced HARQ ACK/NACK information comprises a dedicated bit, added to a HARQ ACK/NACK communication, that indicates the failure of the UE to receive the initial PDCCH communication.
