Abstract

In a wireless communication system where different frequency bands Fl, F2) are deployed to generate various communication zones (22,24), pilot signal set management for a plurality of pilot.Signals generated from an additional coverage zone (24) is based on identifying a preselected signal set from the plurality of pilot signals and determining whether a predetermined criterion is met.

Description

[0001] Claim Priority Pursuant to 35 U.S.C § 119 [0002] This patent application claims the title of "Hand-in and Hand-out Procedures in a Multi-Carrier Communication System" filed on May 20, 2008. 054,762 assigned to the present assignee and expressly incorporated herein by reference. technical field [0003] The present invention relates generally to communications and, more particularly, to pilot set management for non-uniform multi-carrier communication systems. Background technique [0004] In wireless networks, such as wireless cellular networks, network operators typically deploy a minimum amount of bandwidth to provide service coverage to end users in a given geographic area. The foregoing minimal amount of bandwidth is sometimes referred to as an overlay carrier. As user demand increases, network operators add additional bandwidth to increase capacity to meet demand. This extra bandwidth is sometimes referred to as a capacity carrier. In order to meet the need...
