Power saving by combining multiple bandwidth parts (BWPs) into a single wideband channel

An apparatus for wireless communications by a user equipment (UE), comprising:

• means for detecting, in response to a bandwidth part (BWP) switch, a first BWP of a first carrier aggregation signal and a second BWP of a second carrier aggregation signal, each within a predetermined frequency range of each other;
• means for tuning a radio frequency (RF) channel to a center of a wideband channel including the first BWP and the second BWP;
• and
• means for processing the wideband channel including both the first BWP of the first carrier aggregation signal and the second BWP of the second carrier aggregation signal with a single phase locked loop (PLL).

A user equipment (UE), comprising:

• a processor;
• a memory coupled with the processor;
• and
• instructions stored in the memory and operable, when executed by the processor, to cause the UE:
• to detect, in response to a bandwidth part (BWP) switch, a first BWP of a first carrier aggregation signal and a second BWP of a second carrier aggregation signal, each within a predetermined frequency range of each other;
• to tune a radio frequency (RF) channel to a center of a wideband channel including the first BWP and the second BWP;
• and
• to process the wideband channel including both the first BWP of the first carrier aggregation signal and the second BWP of the second carrier aggregation signal with a single phase locked loop (PLL).

A non-transitory computer-readable medium having program code recorded thereon, the program code executed by a processor and comprising:

• program code to detect, in response to a bandwidth part (BWP) switch, a first BWP of a first carrier aggregation signal and a second BWP of a second carrier aggregation signal, each within a predetermined frequency range of each other;
• program code to tune a radio frequency (RF) channel to a center of a wideband channel including the first BWP and the second BWP;
• and
• program code to process the wideband channel including both the first BWP of the first carrier aggregation signal and the second BWP of the second carrier aggregation signal with a single phase locked loop (PLL).
