Managing secondary node and channel assignment based on wireless device characteristics
Systems and methods provide for assignment of wireless devices to a secondary node based on a characteristic of the wireless device and properties of the secondary node. The method may be triggered when noise reaches a predetermined threshold. HPUEs may be assigned to secondary nodes having a high reverse noise and channels having a high spectral efficiency and LPUEs may be assigned to secondary nodes having a lower reverse noise and a lower spectral efficiency.
