Shortened transmission time interval configuration based on user equipment capabilities

A method for wireless communication at a base station, comprising:

• receiving an indicator representing a feedback processing timing capability of a user equipment (UE) to simultaneously process transmissions having a first transmission time interval (TTI) duration according to a first feedback processing timeline and a second TTI duration according to a second feedback processing timeline for each of a plurality of supported bands or band combinations, the first TTI duration being shorter than the second TTI duration;
• scheduling a component carrier within a frequency band of each supported band or band combination of the plurality of supported bands or band combinations based at least in part on the received indicator, wherein the indicator comprises a value pair indicating a supported downlink TTI duration and a supported uplink TTI duration for a first supported band or band combination of the plurality of supported bands or band combinations;
• and
• transmitting information within the frequency band of the component carrier based at least in part on the scheduling.

An apparatus for wireless communication, comprising:

• a processor;
• memory coupled to the processor;
• and
• instructions stored in the memory and operable, when executed by the processor, to cause the apparatus to:
• determine, for each of a plurality of supported bands or band combinations, a feedback processing timing capability of a user equipment (UE) to process transmissions having a first transmission time interval (TTI) duration according to a first feedback processing timeline and a second TTI duration according to a second feedback processing timeline, the first TTI duration being shorter than the second TTI duration;
• and
• transmit an indicator representing the feedback processing timing capability for the each of the plurality of supported bands or band combinations and whether the UE is capable of simultaneously processing the first TTI duration and the second TTI duration in each supported band or band combination of the plurality of supported bands or band combinations, wherein the indicator comprises a value pair indicating a supported downlink TTI duration and a supported uplink TTI duration for a first supported band or band combination of the plurality of supported bands or band combinations.
