Second base stations allow access to wireless devices and configure a second plurality of almost blank subframes. Second base stations configure the same set of subframes as the second plurality of almost blank subframes. Third base stations allow access to a restricted subset of wireless devices and configure a third plurality of almost blank subframes. At least two base stations in the third base stations configure different set of subframes as the second plurality of almost blank subframes."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Almost blank subframe allocation in heterogeneous network","description":"A first base station provides overlapping coverage area with second base stations and third base stations.
