14 . The apparatus of claim 12 , wherein the UE behavior configuration is associated with one or more individual communications associated with the UE that are RRC configured.
15 . The apparatus of claim 9 , wherein the scheduled communication is one of a periodic communication, a communication based on semi-persistent scheduling (SPS), or a communication based on a configured grant (CG).
16 . The apparatus of claim 1 , wherein the indication corresponds to a wakeup signal associated with the second radio, and wherein the preconfigured duration corresponds to a discontinuous reception (DRX) on duration.
17 . The apparatus of claim 1 , further comprising a transceiver coupled to the at least one processor.
18 . A method of wireless communication at a user equipment (UE), comprising:
identifying, while a second radio of the UE is on, a scheduled communication associated with a first radio of the UE, wherein the scheduled communication is independent from an indication via the second radio, wherein the first radio corresponds to a main radio and the second radio corresponds to a low power wake up receiver; and

21 . The method of claim 19 , further comprising:
switching on the second radio after the first radio has been on for the preconfigured duration based on no reception of scheduling information for a further communication associated with the first radio via the first radio while the first radio is on for the preconfigured duration.
22 . The method of claim 19 , further comprising:
receiving, via the first radio, scheduling information for a further communication associated with the first radio from a network node within the preconfigured duration after the first radio is switched on;
