Selectively assigning uplink transmission layers
Selectively assigning uplink transmission layers for uplink transmissions from wireless devices to access nodes based on any combination of uplink usage characteristics and signal conditions. Wireless devices configured to transmit uplink data on one or more orthogonal transmission layers from each antenna. Instructing wireless devices to add transmission layers is based on an uplink usage and other characteristics such as type of transmission, time of day, distance from serving access node, etc.
