Abstract

Methods are provided that enable mitigation of desense from a transmission on a first radio frequency (RF) resource associated with a first SIM to a receiver circuit of a second RF resource associated with a second SIM in the same device. A multi-SIM wireless device, such as a dual-SIM dual active (DSDA) device, may utilize characteristics of uplink and downlink signals to determine an optimal action that reduces interference from conflicting signals. Mitigating actions do not require involvement on the network side, and may greatly improve processing time for implementing interference prevention measures.
