Power saving of wireless communications receivers

A user equipment (UE) comprising:

• one or more radio frequency (RF) chains;
• at least one processor;
• and
• a non-transitory computer-readable storage medium coupled to the at least one processor and storing programming instructions for execution by the at least one processor, the programming instructions instructing the at least one processor to perform operations comprising:
• determining, by the UE in communications with a base station (BS) pursusant to a normal power mode (NPM), whether to enter into a reduced power mode (RPM) for a duration, wherein the NPM is characterized by one or more normal-power parameters comprising a normal sampling frequency and a normal signal bandwidth, wherein the RPM is characterized by one or more reduced-power parameters comprising a reduced sampling frequency compared to the normal sampling frequency of the NPM or a partial signal bandwidth compared to the normal signal bandwidth of the NPM;
• in response to determining to enter into the RPM for the duration, powering down, by the UE, into the RPM by operating with the one or more reduced-power parameters for the duration of the RPM;
• and
• powering up, upon expiry of the duration of the RPM by the UE, into the NPM by resuming to the normal sampling frequency of the NPM and the normal signal bandwidth of the NPM.

A non-transitory computer-readable media storing computer instructions for operating in a reduced power mode (RPM) of a user equipment (UE), that when executed by the UE, cause the UE to perform operations comprising:

• determining, by the UE in communications with a base station (BS) pursusant to a normal power mode (NPM), whether to enter into the RPM for a duration, wherein the NPM is characterized by one or more normal-power parameters comprising a normal sampling frequency and a normal signal bandwidth, wherein the RPM is characterized by one or more reduced-power parameters comprising a reduced sampling frequency compared to the normal sampling frequency of the NPM or a partial signal bandwidth compared to the normal signal bandwidth of the NPM;
• in response to determining to enter into the RPM for the duration, powering down, by the UE, into the RPM by operating with the one or more reduced-power parameters for the duration of the RPM;
• and
• powering up, upon expiry of the duration of the RPM by the UE, into the NPM by resuming to the normal sampling frequency of the NPM and the normal signal bandwidth of the NPM.
