1. An apparatus for wireless communication, comprising:
- a receive chain configured to receive a wireless communication signal and configured to produce an output signal from a wireless spectrum portion of the wireless communication signal when activated;
a signal processor coupled to the receive chain to receive the output signal and to produce a processed signal set; and
a controller coupled to the receive chain and the signal processor and configured to sample the wireless spectrum portion, wherein the wireless spectrum portion comprises a carrier being monitored and at least one other carrier at which one or more non-macro cells are deployed, by activating the receive chain and by employing the signal processor to search the processed signal set for a target non-macro cell pilot.

Abstract
Embodiments include access terminals, computer readable media, and wireless communication systems. These sample a wireless spectrum portion that includes macro cell carrier and at least one other target carrier where non-macro cells are deployed, using a receive chain, a signal processor, and a controller. The wireless spectrum portion is processed to resolve portions corresponding to macro cell carrier and at least one additional carrier where target non-macro cells are deployed. The processed signal is searched for at least one target non-macro cell pilot and the macro carrier portion is used for a paging monitoring operation.

12. A wireless communications apparatus, comprising:
-
means for employing an antenna to convert a portion of a wireless signal to an electric signal; means for employing a signal processor to transform the electric signal into a processed symbol set; and means for employing a data processor to analyze the processed symbol set and extract macro cell paging information pertinent to the apparatus from one carrier of the wireless signal and to extract information indicating presence of a target non-macro cell from another carrier of the wireless signal. - View Dependent Claims (13, 14)
