1. A base station comprising a central scheduler to schedule communications for a plurality of transmitter-receiver pairs, wherein the central scheduler is configured to:
- select a cluster of the transmitter-receiver pairs based on a minimum singular value of direct channel information for each of the pairs; and
instruct the pairs of the selected cluster to perform an interference alignment technique, the interference alignment technique using channel state information.

12. A method for adaptive clustering of transmitter-receiver pairs, the method comprising:
-
selecting a cluster of transmitter-receiver pairs based on a minimum singular value of direct channel information; and instructing the pairs of the selected cluster to perform an interference alignment technique when a target throughput rate can be achieved, wherein performing the interference alignment technique provides an increase an overall achievable throughput for the pairs of the selected cluster. - View Dependent Claims (13, 14, 15, 16)
