1. A method for wireless communications implemented by a user equipment (UE), comprising:
transmitting, by the UE, a data message to a receiver via a first radio access technology of the UE;
storing the data message in a retransmission buffer;
dynamically scaling up or down, by the UE, a size of an acknowledgement window based at least in part on available memory of the UE, wherein the size of the acknowledgement window indicates a threshold quantity for data messages awaiting acknowledgement in the retransmission buffer, and wherein a system memory utilization threshold is less than the size of the acknowledgement window;
transmitting, via the first radio access technology, a feedback request to the receiver in a subsequent data message based at least in part on the system memory utilization threshold for the retransmission buffer being satisfied due to storage of the data message; and
transmitting a low system memory indication to a second radio access technology of the UE different from the first radio access technology based at least in part on the system memory utilization threshold for the retransmission buffer being satisfied.
