摘要：
The multimedia broadcast/multicast service over a single frequency network (MBSFN) can significantly improve the spectral efficiency (SE) by conserving transmitting resources, while broadcasting popular data in the MBSFN mode. As more users demand the same data in all MBSFN area, the energy efficiency will improve. This paper uses a low computational complexity deployment algorithm to optimize the broadcast cells with MBSFN transmissions in stochastic geometry networks. Simulations show that broadcasting with this algorithm has better energy efficiency than both unicasting and broadcasting with point-to-multipoint (PTM) in each cell. The efficiency gain is very important to the user equipment distribution. © 2018, Tsinghua University Press. All right reserved.
