Abstract
The various embodiments include a dual-SIM-dual-active (DSDA) device and methods for implementing pipelining of operation registration data and conflict checking to predict radio frequency co-existence interference between two subscriptions operating on the DSDA device. The DSDA device may predict when a subscription (the “aggressor”) de-senses the other subscription (the “victim”) as a result of the aggressor's scheduled operations, by analyzing the conflicting operation registration data prior to the scheduled operation execution time. The operation registration data is received and analyzed close in time to the scheduled execution of the operation to limit the possibility of changes in the operation schedule and registration data.
