Abstract
The claimed subject matter facilitates sharing antennas among carriers co-located at a base station such to increase throughput of the individual carriers. Thus, the carriers can effectively receive multiple-input/multiple-output (MIMO) from mobile devices though the individual antennas of the carrier alone are not sufficient to receive such signals. A co-sharing interface is provided that takes signals from antennas of one carrier and forwards the signals to a second co-located carrier. In this regard, a carrier can receive signals from a related set of antennas as well as the co-sharing interface component (from a set of antennas related to a disparate carrier) and process the signals in conjunction. Thus, the signals can be disparate portions of a MIMO signal. In addition, the co-sharing interface can modify the signals as defined by the carrier receiving the signals from the interface, such as by applying gain control, alarming, bypass circuitry, and/or amplification.
