1. An apparatus comprising:
at least one processor; and
at least one memory including computer program code;
the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus at least to:
determine, by a network node, a second time domain resource allocation table, the second time domain resource allocation table being different from a first time domain resource allocation table, the first time domain resource allocation table used for indicating time domain resources allocated to a physical downlink shared channel for communications with a user equipment (UE) and the second time domain resource allocation table used for generating one or more hybrid automatic repeat request (HARQ) acknowledgements (ACKs) and negative ACKs (NACKs) by the UE, wherein entries in the first time domain resource allocation table are mapped into overlapping entries in the second time domain resource allocation table, wherein the mapping is determined based at least on a starting or ending allocation symbol;
transmit, by the network node, configuration information to the UE, the configuration information indicating to the UE to use the second time domain resource allocation table for generating the one or more HARQ ACKs and NACKS;
transmit, by the network node, HARQ ACK/NACK bit-bundling information to the UE, the bit-bundling information comprising: a first indication to the UE to use a bit-bundling operation when at least two entries in the first time domain resource allocation table are mapped to one entry in the second time domain resource allocation table, a second indication to the UE to use the bit-bundling operation based on a logical AND operation for ACK and NACKs associated with the at least two entries in the first time domain resource allocation table which have associated downlink control information (DCI) or expected semi persistent scheduling (SPS) physical downlink shared channel (PDSCH) allocations, and a third indication to the UE to use the bit-bundling operation is based on a logical OR operation for ACK and NACKs associated with all entries of a plurality of entries in the first time domain resource allocation table mapped to one entry in the second time domain resource allocation table;
transmit, by the network node, downlink data to the UE; and
in response to transmitting the downlink data, receive, by the network node, the one or more ACKs and NACKs from the UE based on a bit-bundling operation being performed that is based at least on the transmitted bit-bundling information when at least two entries in the first time domain resource allocation table are mapped to one entry in the second time domain resource allocation table.
