Coordinated wireless communications using multiple transmission time intervals

An apparatus for communication, comprising:

• a processor;
• memory in electronic communication with the processor;
• and
• instructions stored in the memory;
• wherein the instructions are executable by the processor to cause the apparatus to:
• determine, in a system that supports communications with a first cell using a first transmission time interval (TTI) duration and communications with a second cell using a second TTI duration that is shorter than the first TTI duration, a first quasi-co-location configuration for the communications with the first cell using the first TTI duration;
• determine a second quasi-co-location configuration for the communications with the second cell using the second TTI duration;
• identify an association between a first quasi-co-location indication of the first quasi-co-location configuration for the communications with the first cell using the first TTI duration and a second quasi-co-location indication of the second quasi-co-location configuration for the communications with the second cell using the second TTI duration;
• and
• perform communications using at least one of the first TTI duration or the second TTI duration, the communications based at least in part on identifying the association.
