1. A method of wireless communication at a network entity, comprising:
transmitting, to a user equipment (UE), an indication of repetitive scheduling of a downlink control channel, wherein the indication triggers a correspondence between the repetitive scheduling of the downlink control channel and one or more repetition factors for one or more uplink control channels other than an uplink control channel that carries one or more acknowledgement (ACK) or negative ACK (NACK) messages for the downlink control channel, each of the one or more repetition factors corresponding to a repetition count for uplink control messages on the one or more uplink control channels; and
receiving, from the UE on the one or more uplink control channels, repetitions of an uplink control message according to a first repetition factor of the one or more repetition factors for the one or more uplink control channels.
 
10. A method of wireless communication at a user equipment (UE), comprising:
receiving, from a network entity, an indication of repetitive scheduling of a downlink control channel, wherein the indication triggers a correspondence between the repetitive scheduling of the downlink control channel and one or more repetition factors for one or more uplink control channels other than an uplink control channel that carries one or more acknowledgement (ACK) or negative ACK (NACK) messages for the downlink control channel, each of the one or more repetition factors corresponding to a repetition count for uplink control messages on the one or more uplink control channels; and
transmitting, to the network entity on the one or more uplink control channels, repetitions of an uplink control message according to a first repetition factor of the one or more repetition factors for the one or more uplink control channels.
 
16. An apparatus for wireless communication at a network entity, comprising:
a transceiver;
a memory configured to store instructions; and
one or more processors communicatively coupled with the transceiver and the memory, wherein the one or more processors are configured to execute the instructions to:
transmit, to a user equipment (UE), an indication of repetitive scheduling of a downlink control channel, wherein the indication triggers a correspondence between the repetitive scheduling of the downlink control channel and one or more repetition factors for one or more uplink control channels other than an uplink control channel that carries one or more acknowledgement (ACK) or negative ACK (NACK) messages for the downlink control channel, each of the one or more repetition factors corresponding to a repetition count for uplink control messages on the one or more uplink control channels; and
receive, from the UE on the one or more uplink control channels, repetitions of an uplink control message according to a first repetition factor of the one or more repetition factors for the one or more uplink control channels.
 
24. An apparatus for wireless communication at a user equipment (UE), comprising:
a transceiver;
a memory configured to store instructions; and
one or more processors communicatively coupled with the transceiver and the memory, wherein the one or more processors are configured to execute the instructions to:
receive, from a network entity, an indication of repetitive scheduling of a downlink control channel, wherein the indication triggers a correspondence between the repetitive scheduling of the downlink control channel and one or more repetition factors for one or more uplink control channels other than an uplink control channel that carries one or more acknowledgement (ACK) or negative ACK (NACK) messages for the downlink control channel, each of the one or more repetition factors corresponding to a repetition count for uplink control messages on the one or more uplink control channels; and
transmit, to the network entity on the one or more uplink control channels, repetitions of an uplink control message according to a first repetition factor of the one or more repetition factors for the one or more uplink control channels.
