Recently, Single-Cell Point-to-Multipoint (SC-PTM) has been studied in 3GPP as an agile broadcast/multicast mechanism. Due to cell-level support of the multicast service, SC-PTM can adjust the service area dynamically and its scheduling is quite agile. In the conventional SC-PTM, however, a single multicast transmission is set for the worst user and provided for all the users regardless of their channel...
We study the radio resource management (RRM) in orthogonal frequency division multiple access (OFDMA) involved heterogeneous networks, to maximize the system sum-rate under the proportional user rate constraint. An analytical model which reflects the network access features is presented. Allowing multi-homing access and resource element sharing, the RRM problem can be formulated as a linear programming...
In the heterogeneous networks, radio resource management (RRM) plays an important role to utilize the potential network diversity. In this paper, we study the RRM strategy in the heterogeneous networks involved with an orthogonal frequency division multiple access (OFDMA) network, with the aim of maximizing the minimum user throughput. An analytical model which reflects the feature of heterogeneous...
