Title:
The method, user terminal, and base station which discover a cell
Document Type and Number:
Japanese Patent JP6190808
Kind Code:
B2
Abstract:
Two alternative embodiments are disclosed to enable a user equipment to efficiently discover small cells using a secondary carrier. The user equipment has a primary carrier link to a base station. In addition, the user equipment has a secondary carrier link to a network node in a small cell within a macro cell supported by the base station. The small cells are discovered through novel beacon signals or through modified PSS/SSS transmissions.
