Abstract: Embodiments of the present invention provide improved systems and methods for adjusting system tests based on detected interference. In one embodiment, a system comprises a host unit; a system test controller to control the performance of system tests, wherein a system test to detect the reception of an interfering signal comprises disabling the generation of tones for transmission through the communication system. The system also comprises multiple remote antenna units communicatively coupled to the system test controller to transmit signals to multiple wireless terminals, wherein a remote antenna unit comprises: an antenna; a transceiver, coupled to the antenna; a signal detector that measures reverse and forward power of signals transmitted to and received from the antenna; and a microcontroller to control the antenna unit, wherein upon receiving a command to perform interference testing, the microcontroller adjusts a subsequent test based on measurements of the reverse power by the signal detector.

Abstract: One embodiment is directed to a method (and system and apparatus) for determining timing for a time division duplex (TDD) signal in a distributed antenna system (DAS). The method comprises (and the system and apparatus are configured for) grouping power samples of a downlink portion of the TDD signal into blocks corresponding to a respective time period, comparing power samples of the blocks to a power threshold, assigning the blocks as ON or OFF based on a number of power samples in a respective block that are above the power threshold, identifying a start of a downlink burst in the TDD signal as an ON block preceded by at least a minimum number of consecutive OFF blocks, and controlling at least one component in the DAS based on the start of the downlink burst.
