Shared channel preparation time for multi-cell scheduling with different subcarrier spacings for scheduled cells

An apparatus for wireless communication at a network entity, comprising:

• one or more memories;
• and
• one or more processors coupled with the one or more memories and configured to cause the network entity to:
• output, via a third cell associated with a third cell subcarrier spacing, a message that schedules a first shared channel communication via a first cell associated with a first subcarrier spacing and a second shared channel communication via a second cell associated with a second subcarrier spacing, wherein the first subcarrier spacing is different than the second subcarrier spacing;
• participate in the first shared channel communication via the first cell at least a time gap after output of the message wherein the time gap is based at least in part on the third cell subcarrier spacing, the first subcarrier spacing, and the second subcarrier spacing;
• and
• participate in the second shared channel communication via the second cell at least the time gap after output of the message.

A method for wireless communications at a user equipment (UE), comprising:

• receiving, via a third cell associated with a third cell subcarrier spacing, a message that schedules a first shared channel communication via a first cell associated with a first subcarrier spacing and a second shared channel communication via a second cell associated with a second subcarrier spacing, wherein the first subcarrier spacing is different than the second subcarrier spacing;
• participating in the first shared channel communication via the first cell at least a time gap after reception of the message, wherein the time gap is based at least in part on the third cell subcarrier spacing, the first subcarrier spacing, and the second subcarrier spacing;
• and
• participating in the second shared channel communication via the second cell at least the time gap after reception of the message.
