Optimal Multicast of Tiled 360 VR Video in OFDMA Systems.
IEEE Communications Letters（2018）
摘要
In this letter, we study optimal multicast of tiled 360 virtual reality (VR) video from one server (base station or access point) to multiple users in an orthogonal frequency division multiple access (OFDMA) system. For given video quality, we optimize the subcarrier, transmission power, and transmission rate allocation to minimize the total transmission power. For given transmission power budget,...
