Abstract: A multistage combining sub-system for a distributed antenna system (“DAS”) is disclosed. The combining sub-system can receive broadband uplink signals from remote units of the DAS. The sub-system can divide the received broadband uplink signals into sets of narrowband uplink signals. The combining sub-system can select subsets of narrowband uplink signals from the sets of narrowband uplink signals. The subsets can be selected based on the narrowband signals in the subsets having a signal characteristic indicative of useful information. The combining sub-system can combine the selected subsets of narrowband uplink signals for routing to a base station. Combining the selected subsets of narrowband uplink signals can involve excluding narrowband uplink signals that are not included in the selected subsets of narrowband uplink signals.

Abstract: Certain aspects involve a wideband remote unit. The wideband remote unit can include one or more antennas and an analog-to-digital converter (“ADC”). The antenna can receive wideband signals. The wideband signals can include an uplink RF signal and a leaked downlink RF signal. The uplink RF signal can have an uplink signal power at or near a noise level. The leaked downlink RF signal can have a downlink signal power greater than the uplink signal power. The ADC can convert the received wideband signals to digital RF signals representing the uplink signal and the downlink signal. The wideband remote unit can transmit the digital RF signals to a unit of a DAS that is in communication with a base station.

Abstract: Certain features relate to compensating for a roundtrip delay caused by a distributed antenna system. A delay unit communicatively coupled to a base station can intercept the delay compensation signaling communicated between the digital baseband unit of the base station and the radio transmitter unit of the base station. The delay unit can adjust the delay compensation signaling by adding to the delay compensation signaling the pre-determined fiber delay caused by the DAS. In some aspects, the delay unit can delay the control words for a base station operating under the Common Public Radio Interface standard. In other aspects, the delay unit can delay the round-trip time measurement message for a base station operating under the Open Base Station Architecture Initiative standard.

Abstract: Systems and methods are provided for optimizing power allocation in distributed antenna systems and other signal distribution systems using variable and static gains. A power optimization sub-system can receive downlink signals from one or more base stations. The power optimization sub-system can group the downlink signals into a first set of downlink signals for which a static gain is to be applied and a second set of downlink signals for which a variable gain is to be applied. The power optimization sub-system can determine a gain for at least some of the signals to which a variable gain is to be applied. The determined gain can be sufficient to achieve a target metric. The power optimization sub-system can apply the static gain to the first set of signals and apply the determined gain to the second set of signals.
