Abstract

This disclosure provides systems, methods and apparatuses for enabling collision mitigation for a user equipment (UE) operating in a dual active mode. In some aspects, the UE may generate a communication for a first subscription in a first time window associated with a first priority for a time domain division pattern with a second subscription. The UE may transmit, using the first subscription, the communication in a second time window associated with a second priority for the time domain division pattern. For example, the second time window associated with the second priority may be a time window in which traffic for the first subscription is prioritized. In some aspects, the UE may select modified periodic intervals for transmissions of a communication to mitigate collisions associated with the time domain division pattern. For example, a transmission time of the periodic communication may be varied (or randomized) over time.
