Abstract
Systems and methods for scheduling transmissions from multi-beam transmitters to sets of receivers are provided. An angle of departure is determined for each of the receivers, and the transmissions to the receivers is then scheduled on the basis of the separation between the angles of departure between the receivers. For example, a constraint may be imposed that no two receivers having an angle of departure separated by less than a first minimum will be scheduled during an even scheduling interfold. Some implementations include a prioritized scheduling system in which high priority receivers are scheduled according to a performance metric subject to the angle departure constraint, and subsequently low priority receivers as scheduled only subject to the angle departure constraint.
