Aspects provide techniques and apparatus for wireless communications (e.g., for saving power when performing control channel processing when in an idle mode or in a 'PDCCH only' in connected mode). An exemplary method includes performing, using a processor, a first type of control channel processing in a first connection state using a firmware image stored in internal memory of the processor, wherein performing control channel processing comprises accessing memory external to the processor, determining one or more conditions for entering a low-power mode (LPM) associated with the processor are satisfied, entering the LPM based on the determination, wherein entering into the LPM includes at least one of disabling or disallowing access to the external memory based on entering the LPM, and performing, using the processor, a second type of control channel processing using the firmware image stored in internal memory of the processor based on entering the LPM.

Power saving via PHY firmware island

Systems and methods for allocating transmit power among multiple interfaces in a wireless communication system are disclosed. In one embodiment, the method comprises determining a first power level used for transmission over a first air interface, determining a second power level used for transmission over a second air interface, comparing a composite of the first power level and the second power level to a threshold power level, and adjusting the second power level based on the comparison.

Allocating transmit power among multiple air interfaces

Systems and methods for allocating transmit power among multiple interfaces in a wireless communication system are disclosed. In one embodiment, the method comprises determining a first power level that is used for transmitting over a first air interface, determining a maximum power level available for transmitting over a second interface, comparing the first power level to the maximum power level, determining a second power level that is used for transmitting over the second air interface based on the comparison of the first power level to the maximum power level, and generating a power-based payload constraint based on the second power level.
