Abstract :

In this paper, the problem of resource management in wireless virtual reality (VR) is studied. Rate of transmission information in VR is essential so for ascertaining low latency in acquiring QoS in VR, mmWave technology should be used. In wireless LAN technology (WLAN) this frequency band is introduced in IEEE802.11ad/ay. Resource allocation in this standard is MU-MIMO with OFDM modulation. Working at mmWave frequency band requires massive number of antenna so for reducing the complexity in hardware it is better to select some number of them by hybrid beamforming. Processing delay, transmission delay and queue delay should be considered in acquiring QoS metric. Our metric is based on these delays that are computed by downlink and uplink rates from hybrid beamforming. Trend of transmission delay and our utility function in various SNR values are analyzed
