Abstract: Embodiments of the disclosure relate to supporting cooperative transmission in massive multiple-input multiple-output (MIMO) systems, such as a wireless distribution system (WDS). A WDS includes a plurality of remote units each defining a home coverage cell. A selected remote unit can coordinate with a neighboring remote unit(s) to help mitigate inter-cell interference for a selected client device(s) located in an overlapping coverage area between the home coverage cell of the selected remote unit and a neighboring coverage cell(s) defined by the neighboring remote unit(s). The selected remote unit receives channel-data information from the selected client device(s) and forms a first radio frequency (RF) beam based on the channel-data information to distribute a downlink signal(s) to the selected client device. The selected remote unit coordinates with the neighboring remote unit(s) based on the channel-data information to form a second RF beam to distribute the downlink signal(s) to the selected client device.

Abstract: Components, systems, and methods for reducing location-dependent destructive interference in distributed antenna systems operating in multiple-input, multiple-output (MIMO) configuration are disclosed. Interference is defined as issues with received MIMO communications signals that can cause a MIMO algorithm to not be able to solve a channel matrix for MIMO communications signals received by MIMO receivers in client devices. These issues may be caused by lack of separation (i.e., phase, amplitude) in the received MIMO communications signals. Thus, to provide amplitude separation of received MIMO communications signals, multiple MIMO transmitters are each configured to employ multiple transmitter antennas, which are each configured to transmit in different polarization states. In certain embodiments, one of the MIMO communications signals is amplitude adjusted in one of the polarization states to provide amplitude separation between received MIMO communications signals. In other embodiments, multiple transmitter antennas in a MIMO transmitter can be offset to provide amplitude separation.
Abstract translation: 公开了用于减少在多输入多输出（MIMO）配置中工作的分布式天线系统中的位置相关的破坏性干扰的组件，系统和方法。 干扰被定义为接收的MIMO通信信号的问题，这可能导致MIMO算法不能解决由客户端设备中的MIMO接收机接收的MIMO通信信号的信道矩阵。 这些问题可能由接收的MIMO通信信号中的分离（即，相位，振幅）的缺失引起。 因此，为了提供接收的MIMO通信信号的幅度分离，多个MIMO发射机被配置为使用多个发射机天线，每个发射机天线被配置为以不同的极化状态发射。 在某些实施例中，MIMO通信信号中的一个被调整为偏振状态之一，以提供接收的MIMO通信信号之间的幅度间隔。 在其他实施例中，MIMO发射机中的多个发射机天线可以被偏移以提供振幅分离。

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: Embodiments of the disclosure relate to a massive multiple-input multiple-output (M-MIMO) wireless distribution system (WDS) and related methods for optimizing the M-MIMO WDS. In one aspect, the M-MIMO WDS includes a plurality of remote units each deployed at a location and includes one or more antennas to serve a remote coverage area. At least one remote unit can have a different number of the antennas from at least one other remote unit in the M-MIMO WDS. In another aspect, a selected system configuration including the location and number of the antennas associated with each of the remote units can be determined using an iterative algorithm that maximizes a selected system performance indicator of the M-MIMO WDS. As such, it may be possible to optimize the selected system performance indicator at reduced complexity and costs, thus helping to enhance user experiences in the M-MIMO WDS.

Abstract: A communication circuit in a wireless communications system (WCS) is provided. The WCS employs self-interference cancellation (SIC) circuitry to suppress an interference signal(s) associated with an uplink communications signal(s) in a target uplink band(s). A communication circuit is employed to provide more accurate temporal and phase estimates about interference signal(s) in the target uplink band(s). The communication circuit utilizes an anchor downlink signal, which can be any of the downlink communications signals communicated in the WCS, to help determine an optimal phase shift for uplink communications signal(s) in the target uplink band(s). Accordingly, the SIC circuitry can suppress the interference signal(s) in the target uplink band(s) based on the optimal phase shift. By determining the optimal phase shift in the target uplink band(s), it is possible to achieve accurate temporal and phase synchronization in the SIC circuitry, thus helping to achieve higher and more stable interference suppression in the WCS.

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.
