Pipelining Registration and Conflict Detection in Dual-SIM-Dual-Active Communication Device Coexistence

摘要

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.

主权项

1. A method of mitigating interference between communication operations in a wireless communication device having a shared processor configured to execute the method, the method comprising:
receiving, in a co-existence manager configured to be executed by the shared processor, data of a first future communication operation of a first communication circuit to occur in a future time slot prior to the future time slot; comparing the data of the first future communication operation with data of a second future communication operation of a second communication circuit prior to the future time slot by the co-existence manager; determining based on the data of the first and second future communication operations whether a conflict will occur between the first and second future communication operations during the future time slot by the co-existence manager; and implementing an interference mitigating operation during the future time slot in response to determining that the conflict will occur between the first and second future communication operations during the future time slot, by the shared processor.
