Description

To maximize the sum rate under the constraint of both the total power and the minimal rate provision of the multicast service. The main contributions of this paper can be summarized as follows: the system provide a quantitative study on an adaptive resource allocation scheme by jointly considering IC and LB in MCNs. The system also presents a novel frequency reuse scheme to mitigate interference and maintain high spectral efficiency. The resource planning domain is benefitted by adapting orthogonal frequency division multiple accesses (OFDMA) as multiple access mechanism (recommended by third generation partnership project – Long Term Evolution (3GPP- LTE standard). The resource allocation in OFDMA ensures that no two users are assigned a common resource in a cell at a given time, thereby eliminating intra- cell interference (due to transmissions within the cell). Now, main research focus is on inter- cell interference (ICI).
