Predictive control for radio frequency coexistence management in multi-rf communication device

A multi-RF communication device, comprising:

• a memory;
• a plurality of radio frequency (RF) resources;
• and
• a processor coupled to the memory, and the plurality of RF resources, wherein the processor is configured with processor-executable instructions to perform operations comprising:
• determining a time that an RF coexistence event between a victim subscription (“victim”) and an aggressor subscription (“aggressor”) will next start, wherein:
• the RF coexistence event comprises a period in which uplink transmissions on a first RF resource overlap in time with downlink reception on a second RF resource;
• and
• the aggressor activity is supported by a first wireless communication network associated with the first RF resource and the victim activity is supported by a second wireless communication network associated with the second RF resource;
• determining whether a selected power-control remedial action is viable;
• and
• implementing the selected power-control remedial action upon the start of the next RF coexistence event in response to determining that the selected power-control remedial action is viable, wherein implementing the selected power-control remedial action comprises:
• sending a power UP command on the victim's closed-loop downlink power control 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
• sending a power DOWN command on the victim's closed-loop downlink power control to the second wireless communication network just after the transmission by the aggressor finishes.

A multi-RF communication device, comprising:

• means for determining a time that an RF coexistence event will next start between an aggressor subscription (“aggressor”) and a victim subscription (“victim”), 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 the victim activity 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;
• means for determining whether the selected power-control remedial action is viable;
• and
• means for implementing the selected power-control remedial action upon the start of the next RF coexistence event in response to determining that the power-control remedial action is viable, wherein the means for implementing the selected power-control remedial action comprises:
• means for sending a power UP command on the victim's closed-loop downlink power control to the second wireless communication network just before a transmission by the aggressor is about to start;
• means for waiting for the aggressor to finish the transmission;
• and
• means for sending a power DOWN command on the victim's closed-loop downlink power control to the second wireless communication network just after the transmission by the aggressor finishes.

A non-transitory processor-readable storage medium having stored thereon processor-executable software instructions configured to cause a processor of a multi-RF communication device to perform operations comprising:

• determining a time that an RF coexistence event will next start between an aggressor subscription (“aggressor”) and a victim subscription (“victim”), 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 the selected power-control remedial action is viable;
• and
• implementing the selected power-control remedial action upon the start of the next RF coexistence event in response to determining that the power-control remedial action is viable, wherein implementing the selected power-control remedial action comprises:
• sending, to the second wireless communication network, 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
• sending, to the second wireless communication network, a power DOWN command on the victim's closed-loop downlink power control just after the transmission by the aggressor finishes.
