System Architecture for a Cellular Network with Cooperative Mobile Relay

This paper describes a comprehensive system architecture that enables mobile-to-mobile communications for the purpose of enhancing the capacity of the cellular network. The architecture is developed using LTE Release-10 as the baseline. The impact on the protocol stack is discussed in detail. Neighbor discovery mechanisms are described to enable users to identify potential helper mobiles to enable a cooperative mobile relay. Resource partitioning for the mobile-to-mobile link is detailed and changes to the design of the HARQ entity structure and timing are discussed.

Uplink system capacity of a cellular network with cooperative mobile relay

This paper studies the performance of a hybrid cellular network with cellular controlled direct radio links between multiple mobile User Equipments (UEs). The main focus is on the uplink of the proposed system with multiple idle UEs acting as relays to assist the communication of any given UE with an active connection. In the presence of multiple UEs as relays, the Base Station (BS) dynamically chooses the best relay to maximize the throughput of each radio link. We present system capacity results using Monte Carlo system simulation techniques. Further, we compare results with and without the use of distributed beam forming techniques. Our results indicate that cell edge capacity could be improved by more than 99% by using idle UEs in the system as mobile relays. The performance improvement at cell edge is achieved while improving the mean cell throughput by more than 50%.

Mobility management for dense networks

This paper considers a Wireless Local Area Network consisting of Access Points that can provide only a limited cone of coverage. A dense access point deployment is required for such a network to provide coverage over a substantial area. Such a deployment introduces challenges associated with support of terminal mobility, backhaul management load and association. In this paper, we propose simple yet effective solutions to these problems.
