Patent ID: 8532039

Claim:
A wireless transmit/receive unit (WTRU) comprising: a front-end unit (FEU) configured to receive a radio frequency (RF) signal and to generate a plurality of time-interleaved samples, wherein the FEU includes: an array of time-interleaved bandpass charge samplers configured to activate based on a predetermined threshold; and an array of time-interleaved voltage samplers configured to activate based on the predetermined threshold; a signal processing unit (SPU) configured to receive and combine the plurality of time-interleaved samples and to generate a signal quality measurement and in-phase and quadrature-phase (IQ) complex samples; a resource management unit (RMU) configured to receive the signal quality measurement and allocate FEU resources in conjunction with a front-end unit controller (FEUC) based on the signal quality measurement; and wherein the FEUC is configured to generate a plurality of control signals based on the received signal quality measurement from the RMU, and wherein on a condition that the signal quality measurement is below the predetermined threshold, a plurality of time-interleaved bandpass charge samplers and a plurality of time-interleaved voltage samplers are activated.
