In order to deliver mobile services, multimedia broadcast multicast services (MBMSs) over single frequency networks (MBSFNs) have been standardized for long term evolution (LTE) systems, where an MBSFN comprises a number of synchronized base stations (BSs) cooperatively multicasting MBMS streams. In this letter, we propose a two-phase power allocation algorithm for an MBSFN. The algorithm first decides...
This paper proposes a resource allocation algorithm for multicasting video streams to users with diverse screen sizes. In order to gain from multicasting, quality of the channel has to be sufficiently high for the all users, and probability that such channel happens become lower as the number of the users grows. Therefore, this paper considers orthogonal frequency division multiple access (OFDMA)...
This paper presents a joint resource allocation and interference avoidance algorithm for uplink transmissions in a multi-cell cognitive radio network (CRN), which overlays with a multi-cell primary network (PN). We consider a primary willingness based coexistent architecture. Primary base stations will broadcast pilot signals and interference margins to the CRN for interference channel evaluation...
