Embodiments of the present invention relate to a wireless communication system, and more particularly, to a technology for allocating a Channel State Information-Reference Signal in a wireless communication system. In some examples, this may be achieved by generating maps that use non-physical locations that are still within standard location data formats at a game service provider and providing the maps andor map data to map server providers showing game worlds mapped to those coordinates. A first set of ports from the multiple ports and a second set of ports from the multiple ports are managed by a first network control entity when the switch fabric system is in a first configuration. X may be one or more elements selected from the group of alkaline metal and Tl element.
