Aspects of this disclosure relate to user equipment rate selection. Sum rates can be compared including and excluding a candidate layer. Based on the comparison, the candidate layer can be included in a layer set. Rate selection for user equipments of a cluster can be performed based on the layer set. In certain applications, user equipment rate selection can be performed for multiple clusters of user equipments and network nodes. In such applications, inter-cluster interference can be nulled.

Rate selection for user equipments of cluster

Aspects of this disclosure relate to forming clusters of user equipments and network nodes. A first cluster of first user equipments and first network nodes in a first section can be formed for a time slot. A second cluster of second user equipments and second network nodes in a second section can be formed for the time slot such that the first user equipments are protected from interference associated with the second cluster. During the time slot, the first section has higher priority than the second section. Multiple-input multiple-output wireless communications can occur during the time slot (a) from the first network nodes to the first user equipments and (b) from the second network nodes to the second user equipments.
