Abstract

Official abstract text for this publication.

A wireless transmit/receive unit (WTRU) is described. The WTRU includes a front-end unit (FEU), a signal processing unit (SPU), and a resource management unit (RMU). The FEU receives a radio frequency (RF) signal, generates time-interleaved samples, an includes: a first array of first time-interleaved samplers, a second array of second time-interleaved samplers, and a third array of third time-interleaved samplers. The SPU receives and combines the plurality of time-interleaved samples and generates a signal quality measurement and in-phase and quadrature-phase (IQ) complex samples. The RMU receives the signal quality measurement and allocates FEU resources in conjunction with a front-end unit controller (FEUC) based on the signal quality measurement. The FEUC generates control signals based on the received signal quality measurement from the RMU.

First claim

Opening claim text (preview).

What is claimed: 1. A wireless transmit/receive unit (WTRU), the 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: a first array of first time-interleaved samplers, a second array of second time-interleaved samplers, and a third array of third time-interleaved samplers; a signal processing unit (SPU) configured to receive and combine the plurality o…
