1. An apparatus configured for wireless communications, comprising:
a memory comprising computer-executable instructions; and
a processor configured to execute the computer-executable instructions and cause the apparatus to:
receive a beam failure recovery response (BFRR) message on a second cell, wherein the BFRR message is associated with failure of a beam associated with a first cell; and
communicate on the first cell using a default beam after a duration starting from reception of the BFRR message, wherein the duration comprises a larger of a first duration of a fixed number of symbols based on a first subcarrier spacing (SCS) of the first cell and a second duration of the fixed number of symbols based on a second SCS of the second cell.
