Abstract: A method and an apparatus for a light active estimation mechanism for backhaul management at a small cell base station are disclosed. For example, the method may include transmitting a first data packet from the small cell base station to a network entity, receiving a second data packet from the network entity in response to the transmission, calculating a time delay between the transmitting of the first data packet and the receiving of the second data packet, and determining whether or not a backhaul of the small cell base station is congested based on the calculated time delay. As such, light active estimation mechanism for backhaul management at a small cell base station may be achieved.

Abstract: A test system emulates the analog processing portion of a communication device and adjusts input signals based on distortions specified by a user and control signals generated by a baseband processing portion of the communication device. The distortions can be specified in terms of the baseband. One or more of the control signals can be bypassed to investigate the effect of each of the control signals alone, or in various combinations. An operator interface can be provided that allows the user to set up and conduct the tests, and monitor the results. Facilities are also provided to allow the reference voltage at the baseband processing portion to be adjusted while maintaining the appropriate reference voltage for components in the test system.
