Abstract

Systems and methods presented herein provide for optimizing or otherwise improving capacity in a communication network. In one embodiment, a method is operable in a network hub that is communicatively coupled to UEs via a plurality of communication links. Each communication link has a different data rate capacity and each UE comprises a profile that indicates its data rate capabilities (e.g., modulation schemes and the like). The method includes detecting communications of the UEs, determining the data rate capabilities of the UEs from their profiles, and determining how many different data rate capacities the network hub supports over the communication links. The method also includes grouping the UEs according to their data rate capabilities, generating a common profile for each UE group, and assigning the communication links to the UE groups based on their common profiles.
