Abstract

Devices and methods to use base stations to communicate with user equipment (UE) terminals in an indoor setting are disclosed. For example, user equipments such as mobile telephone devices may be used in a building with multiple floors. The building may be supplied with antenna elements organized into antenna groups with each group serving an area of the building—a floor for example. The base station, utilizing the antenna groups, communicates with the UE terminals via one or more radio resources. The base station manages radio resources to communicate with multiple UE terminals. The base station selectively activates and deactivates the antenna groups to reduce multiple access interference and to efficiently utilize the radio resources.
