Handling of non-numeric data to flow control feedback timing

A method for wireless communication implemented by a base station, comprising:

• transmitting, to a user equipment (UE), first downlink control information scheduling a first downlink data transmission, the first downlink control information indicating a non-numeric data-to-flow control feedback timing;
• transmitting, to the UE, second downlink control information scheduling a second downlink data transmission, the second downlink control information indicating a numeric data-to-flow control feedback timing;
• transmitting, to the UE, third downlink control information activating semi-persistent scheduling downlink data transmissions from the base station and indicating resources of a first uplink channel allocated for flow control feedback for a semi-persistent scheduling downlink data transmission of the semi-persistent scheduling downlink data transmissions;
• and
• receiving flow control feedback for the first downlink data transmission based at least in part on a second uplink channel corresponding to the numeric data-to-flow control feedback timing and the first uplink channel.

An apparatus for wireless communication implemented by a user equipment (UE), comprising:

• a processor,
• memory coupled with the processor;
• and
• instructions stored in the memory and executable by the processor to cause the apparatus to
• receive, from a base station, first downlink control information scheduling a first downlink data transmission, the first downlink control information indicating a non-numeric data-to-flow control feedback timing;
• receive, from the base station, second downlink control information scheduling a second downlink data transmission, the second downlink control information indicating a numeric data-to-flow control feedback timing;
• identify resources of a first uplink channel allocated for flow control feedback for a semi-persistent scheduling downlink data transmission;
• and
• manage a flow control feedback for the first downlink data transmission based at least in part on a second uplink channel corresponding to the numeric data-to-flow control feedback timing and the first uplink channel.
