METHOD AND APPARATUS FOR DYNAMIC BACKHAUL RESOURCE ALLOCATION IN A RADIO ACCESS NETWORK

摘要

Methods and apparatus for resource allocation in the backhaul network of a radio access network are provided. Devices such as schedulers communicate utility functions to a traffic engineering controller. Each utility function expresses amount of utility associated with at least one prospective backhaul resource allocation, from the perspective of the device or clients or UEs served thereby. The traffic engineering controller incorporates the utility functions into an objective to be maximized, subject to constraints such as backhaul link capacity constraints. A backhaul resource allocation is determined by solving a corresponding optimization problem. The traffic engineering controller then instructs various entities in the backhaul network to implement the resource allocation.
