In this paper a novel resource allocation scheme is presented that beneficially exploits these potentials of relaying by means of concurrent resource scheduling under control of a central station.
While such work made great strides toward understanding the potential of relay networks, it dealt mainly with ideal configurations with no interference.
We propose two key radio resource management techniques to exploit the full potential of relay enhanced cellular OFDMA networks: dynamic and flexible resource assignment in a relay enhanced cell and cooperative relaying.
A large number of cooperative techniques have been reported in the literature showing the potential of relay-assisted scenarios.
In Section 3 the potential of relaying in a setting with a complete channel model was seen.
A fixed and static resource assignment will not allow to exploit the full potential of relay-based deployments since the relay deployments can have very different properties as illustrated in Section 3. Therefore, we propose that the BS flexibly assigns parts or all of the available system resources to itself and to each RS in the relay enhanced cell.
On taking these results together, CAMTA have the potential of relaying calcium signalling via calmodulin binding domain and stress signalling via CG-1 and ABRE binding motif.
Thus, without properly assigning the resources inside the cell the potential benefits of relaying are lost and the performance might even degrade.
The resource allocation of cellular users has a significant impact on the potential gains of relay-aided D2D transmissions, and relay selection has an important influence on the resource allocation scheme.
Even though these assessment results have been obtained for WINNER OFDMA parameters, they give also insights on the potential benefits of relays for OFDMA-based cellular systems like WiMAX and 3GPP Long-Term Evolution (LTE).
