Scheduling of transmission time intervals

A method comprising:

• determining a first semi-persistent scheduling resource assignment indicating a first set of resources, the first set of resources comprising a first plurality of time domain resources, wherein each time domain resource of the first plurality of time domain resources has a first transmission time interval length;
• determining a second semi-persistent scheduling resource assignment indicating a second set of resources, the second set of resources comprising a second plurality of time domain resources, wherein each time domain resource of the second plurality of time domain resources has a second transmission time interval length, and wherein the first transmission time interval length is different from the second transmission time interval length;
• transmitting the first semi-persistent scheduling resource assignment using a first semi-persistent scheduling radio network identifier;
• and
• transmitting the second semi-persistent scheduling resource assignment using a second semi-persistent scheduling radio network identifier.

An apparatus comprising:
