1. A method, comprising:
- utilizing a hierarchical structure to organize at least one node base station (nodeB) and at least one home node base station (home nodeB), wherein the hierarchical structure prioritizes a home nodeB over a nodeB;
receiving a portion of data related to system information block (SIB) from at least one of a nodeB and a home nodeB, wherein the SIB is configured to enable a user equipment (UE) to discover the home nodeB;
communicating a detection notification related to a home nodeB to a macro network; and
employing at least one of the hierarchical structure or the portion of data related to SIB to enable the UE to select between the home nodeB or the nodeB.

Abstract
Systems and methodologies are described that facilitate cell search, selection, and reselection within a wireless communication network that includes a home node base station (home nodeB). A user equipment (UE) can detect a home nodeB and communicate such identification to a macro network that includes at least one node base station (nodeB). The detected home nodeB and nodeB can be hierarchically structured in order to prioritize connectivity with the home nodeB over the nodeB. Such prioritization can be implemented by broadcasting home nodeB parameters and macro nodeB parameters having identification information therewith.
