Providing for access point assisted signal acquisition for heterogeneous access point wireless networks is described herein. By way of example, a closed subscriber group (CSG) base station, such as a home NodeB (HNB) can be configured to provide temporary, limited access to a UE that is not authorized to access the HNB. Upon receiving and rejecting an access probe, the HNB can negotiate with a surrounding macro network to provide service for the UE. Further, the HNB can forward signal acquisition data, to assist in proper decoding of pilot or synchronization signals of the macro network. In particular aspects, the HNB can reduce power or blank transmissions on reserved access resources to reduce interference for the UE. By these and other disclosed mechanisms, the HNB can assist a non-CSG subscriber to obtain network service, and mitigate interference effects due to proximity to the UE.
