Predictive control for radio frequency coexistence management in multi-SIM-multi-active (MSMA) devices

A method for implementing a radio frequency (RF) coexistence management strategy on a multi-RF communication device for managing effects of an aggressor communication activity (“aggressor”) on a victim communication activity (“victim”), comprising:

• determining when an RF coexistence event will next start, wherein:
• the RF coexistence event comprises a period in which uplink transmissions on a first RF resource of the communication device overlap in time with downlink reception on a second RF resource of the communication device, and
• the aggressor is supported by a first wireless communication network associated with the first RF resource and the victim is supported by a second wireless communication network associated with the second RF resource:
• determining whether a power-control remedial action is viable;
• and
• implementing the power-control remedial action when the RF coexistence event will next start in response to determining that the power-control remedial action is viable, wherein implementing the power-control remedial action comprises:
• configuring the victim to send a power UP command on the victim's closed-loop downlink power control just before a transmission by the aggressor is about to start;
• waiting for the aggressor to finish the transmission;
• and
• configuring the victim to send a power DOWN command on the victim's closed-loop downlink power control just after the transmission by the aggressor finishes.

A multi-radio frequency (RF) communication device, comprising:

• a memory;
• at least a first RF resource and a second RF resource;
• and
• a processor coupled to the memory, the first RF resource, and the second RF resource, wherein the processor is configured with processor-executable instructions to:
• determine when an RF coexistence event between a victim communication activity (“victim”) and an aggressor communication activity (“aggressor”) will next start, wherein:
• the RF coexistence event comprises a period in which uplink transmissions on the first RF resource overlap in time with downlink reception on the second RF resource, and
• the aggressor is supported by a first wireless communication network associated with the first RF resource and the victim is supported by a second wireless communication network associated with the second RF resource;
• determine whether a power-control remedial action is viable;
• and
• implement the power-control remedial action when the RF coexistence event will next start in response to determining that the power-control remedial action is viable, wherein the processor is further configured with processor-executable instructions to implement the power-controlled remedial action by:
• configured the victim to send a degraded channel quality indicator (CQI) report to the second wireless communication network just before a transmission by the aggressor is about to start;
• waiting for the aggressor to finish the transmission;
• and
• configuring the victim to send a non-degraded CQI report to the second wireless communication network just after the transmission by the aggressor finishes.
