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.

Claim (Index 1):
A communications system, comprising:\n a plurality of remote units comprising optical-to-electrical converters and electrical-to-optical converters, each configured to define a home coverage cell among a plurality of coverage cells in the communications system to communicate one or more downlink signals to one or more client devices located within a boundary of the home coverage cell; and a central unit comprising electrical-to-optical converters and optical-to-electrical converters and communicatively coupled to the plurality of remote units over an optical fiber-based communications medium, wherein a selected remote unit among the plurality of remote units is configured to:\n identify at least one selected client device located in at least one overlapping coverage area between the home coverage cell of the selected remote unit and at least one neighboring coverage cell defined by at least one neighboring remote unit among the plurality of remote units; \n receive channel-data information from the at least one selected client device; \n form a first radio frequency (RF) beam based on the channel-data information to distribute at least one first downlink signal among the one or more downlink signals to the at least one selected client device; and \n coordinate with the at least one neighboring remote unit based on the channel-data information to form at least one second RF beam to distribute the at least one first downlink signal from the at least one neighboring remote unit to the at least one selected client device, and \n the selected remote unit and the at least one neighboring remote unit are configured to form the respective first RF beam and the at least one second RF beam based on a defined time-frequency resource.
