A method includes obtaining a plurality of conflict lists including a conflict list for each communication device. The method also includes obtaining resource requirement values. A resource requirement value indicates a number of orthogonal channels that are required to satisfy demand associated with a communication device. The method includes determining that two or more communication devices are associated with a particular resource requirement value. The method also includes selecting a particular communication device by using the conflict lists to perform a maximum independent set analysis based on the two or more communication devices. The method further includes assigning a set of orthogonal channels to the particular communication device. The set of orthogonal channels include a number of orthogonal channels that is based on the particular resource requirement value. The method also includes configuring a communication system to communicate with the particular communication device based on the set of orthogonal channels.

Systems and methods for reuse of spectrum resources

A distributed beamforming system including a platform terminal and a plurality of user terminals is disclosed. An individual user terminal includes a receiver configured to receive a plurality of individual wireless signals, where the plurality of individual wireless signals are transmitted by the platform terminal and are orthogonal with respect to one another. The individual user terminal also includes one or more frequency converters configured to transform each of the plurality of individual wireless signals to an intermediate frequency. The individual user terminal is configured to coherently combine the plurality of individual wireless signals together to form a beamformed signal.

Distributed beamforming system with user side beamforming processing

A distributed beamforming system includes a platform terminal and a plurality of user terminals. The platform terminal includes an antenna array including a plurality of antenna elements. Each antenna element transmits a wide-area beam configured to encompass each of the plurality of user terminals. The platform terminal also includes one or more processors in electronic communication with the antenna array and a memory coupled to the one or more processors. The memory stores data into a database and program code that, when executed by the one or more processors, causes the platform terminal to receive an incoming signal and split the incoming signal into a plurality of individual wireless signals. Each individual wireless signal corresponds to one of the plurality of antenna elements of the antenna array. The system also transmits the plurality of individual wireless signals to the user terminal by the antenna array.

A method of coordinating reuse of spectrum in a communication system in which a communication node is configured to communicate with devices that are located in multiple regions is described. The method includes obtaining a maximum interference constraint, and determining respective conflicts lists for one or more individual regions of the multiple regions. The conflicts list for each individual region includes at least one other region of the multiple regions for which a pairwise interaction with the individual region violates the maximum interference constraint. Further, the method includes assigning spot beam colors to the multiple regions using the determined conflicts lists such that pairs of regions that violate the maximum interference constraint with respect to one another are assigned different spot beam colors. Still further, the method includes causing the communication node to configure multiple spot beams in accordance with the assigned spot beam colors.
