Receiver front-end power consumption reduction via linearity and sensitivity adaptation

A wireless communication device may operate in different power modes based at least on a decoding of a Physical Data Control Channel (PDCCH). The wireless communication device may operate its receiver front end circuitry (RX AFE) in any one of a number of different power modes, and may switch to ope...

More Information
Summary:A wireless communication device may operate in different power modes based at least on a decoding of a Physical Data Control Channel (PDCCH). The wireless communication device may operate its receiver front end circuitry (RX AFE) in any one of a number of different power modes, and may switch to operating the RX AFE in a different power mode based at least on decoding of the PDCCH. The transmit leakage does not need to be monitored, and the wireless communication device may adjust/adapt the sensitivity and linearity of its RX AFE based on PDCCH decoding and in some cases based additionally on one or more metrics, to reduce power consumption. The different power modes may correspond to different respective combinations of sensitivity level and linearity level at which the RX AFE is operating.
