Abstract: Embodiments of the disclosure relate to a multi-source same-cell wireless distribution system (WDS) with dynamic source adaptation. In this regard, the WDS includes multiple remote units each configured to distribute a downlink communications signal having identical cell identification in a respective coverage area. The WDS includes a signal distribution circuit communicatively coupled to multiple signal sources. The signal distribution circuit can dynamically determine a selected coverage cell among multiple coverage cells having a client device load higher than a predefined load threshold. Accordingly, the signal distribution circuit can redistribute the defined source capacity of a selected signal source among the multiple signal sources exclusively to the selected coverage cell. By dynamically distributing more capacity to the selected coverage cell with higher client device load, it is possible to increase data throughput, thus helping to provide improved user experience in the selected coverage cell.

Abstract: Wideband digital distributed communications systems (DCSs) employing reconfigurable digital signal processing circuit for scaling supported communications services are disclosed. The DCS includes a head-end unit that includes front end downlink signal processing circuit to receive and distribute downlink communications signals for communications services (i.e., communications bands) to remote units. The remote units also include front end uplink signal processing circuits to receive uplink communications signals to be distributed to the head-end unit. The front end signal processing circuits are either equipped with broadband filters, or such filters are eliminated, to allow the DCS to be scaled to pass added communications bands. The front end processing circuits include analog-to-digital conversion (ADC) circuits for converting received analog communications signals into digital communications signals so that the digital communications signals can be processed by digital signal processing circuit that can flexibly be configured and reconfigured to support the added communications bands.

Abstract: Supporting distributed massive multiple-input multiple-output (DM-MIMO) in a distributed communications system (DCS) is disclosed. The DCS includes multiple remote units each configured to communicate downlink and uplink radio frequency (RF) communications signals with a number of user equipment (UEs) at different UE locations in the DCS. Each remote unit includes multiple antennas, multiple RF chains, and an RF switch circuit configured to dynamically couple the RF chains to a subset of antennas in accordance to the UE locations such that the subset of antennas can be activated to concurrently radiate the downlink RF communications signals and absorb the uplink RF communications signals. By dynamically activating the subset of antennas in accordance to the UE locations, it is possible to optimize signal strength and channel quality for each UE in the DCS, thus making it possible to improve wireless data capacity of the DCS with negligible additional hardware cost.
