Selectively providing system information in a heterogeneous network environment
First Claim
1. An apparatus for selectively providing system information in a heterogeneous network environment including a first network overlaid on a second network, the apparatus comprising:
- a location determination unit configured to receive an uplink signal transmitted from user equipment and to determine a first network base station in the first network, which is closer to the user equipment, as compared to other first network base stations in the first network;
a mapping table configured to store information on at least one second network cell in a second network, which is overlaid on a first network cell of the determined first network base station, and is spatially in a comparatively close distance to the determined first network base station in the first network among, as comparted to other second network cells overlaid on the first network cell of the determined first network base station; and
a signal processor configured to determine, among the entire second network cells overlaid on the first network cell of the determined first network base station, at least one second network cell spatially close to the determined first network base station based on the mapping table, to obtain system information of the determined at least one second network cell.

Abstract
Described embodiments provide an apparatus and method for selectively providing system information in a heterogeneous network environment including a first network overlaid on a second network. The apparatus may include a location determination unit, a mapping table, and a signal processor. The location determination unit may be configured to determine a first network base station in the first network. The mapping table may be configured to store information on at least one second network cell in a second network, which is spatially in a comparatively close distance to each first network base station in the first network. The signal processor may be configured to determine at least one second network cell spatially close to the determined first network base station based on the mapping table and to transmit system information of the at least one second network cell to the user equipment.

11. A method for selectively obtaining system information in a heterogeneous network environment including a first network overlaid on a second network, the method comprising:
-
receiving an uplink signal transmitted from user equipment; determining, among a plurality of first network base stations included in a first network cell, one first network base station closer to the user equipment, as compared to the other of the plurality of first network base stations; determining, among entire second network cells overlaid on the first network cell of the determined first network base station, at least one second network cell mapped to the determined first network base station based on a mapping table including a mapping relation between the first network base stations and the second network cells; and obtaining system information, to be provided to the user equipment, of the determined at least one second network cell, wherein the mapping table includes information on one or more overlaid second network cells in the second network spatially in a comparatively close distance to each of the first network base stations included in the first network cell, as compared to other second network cells among the entire second network cells overlaid on the first network cell. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18)
