    Abstract: Certain features relate to a digital multichannel interface between a base station and a repeater in a telecommunications system, such as a distributed antenna system. The digital multichannel interface can provide streams of I/Q samples that carry information from multiple carriers of a wideband communications signal as well as semi-static control information for the telecommunications system. The digital multichannel interface can also transport frame timing information between the base station and the repeater. The frame timing information can maintain synchronization between the uplink transmit frames carrying uplink I/Q samples and the downlink transmit frames carrying downlink I/Q samples.

    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 signal powers above a threshold signal power. 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: The present disclosure describes devices, systems, and methods for allocating bandwidth among communication links in a telecommunication system. Some aspects can involve identifying multiple transmission modes used to transmit downlink signals via remote units of a telecommunications system to groups of terminal devices. Each group of terminal devices may receive downlink signals using a respective transmission mode. Respective weights can be assigned to the groups of terminal devices based on the transmission modes. The downlink signals, which are provided to each remote unit associate with each group of terminal devices, can be configured using a respective signal power that is associated with a respective weight for the group of terminal devices associated with the respective remote unit.

    Abstract: Certain features relate to a remote antenna unit having a multi-stage isolation sub-system for isolating uplink and downlink signal paths. A multi-stage isolation sub-system in the remote antenna unit can include a first stage device that is configured to generate a cancellation signal for canceling unwanted downlink signals received at the uplink antenna. The isolation sub-system can also include a second stage device configured to generate a cancellation signal that attenuates residual noise and intermodulation products generated in the downlink path and received in the uplink path. The multi-stage isolation sub-system can combine the cancellation signals with signals received on the uplink path in order to cancel or attenuate downlink leakage signals and residual noise present on the uplink path.
