Abstract
Various methods and communications devices to reduce a bandwidth utilization of a backhaul link in a wireless communications system are provided. By way of example, bandwidth utilization is reduced by relegating the compression of data to the downlink transmission, storing only reference keys in the cache of the transmitting device, and taking advantage of an asymmetrical cache structure between communicating devices. Support is provided for a user equipment to move from one node to another node.
