In　the　realm　of　6G　wireless　networks,　virtual　reality　(VR)　360-degree　videos　stand　out　as　a　pivotal　application.　Researches　on　the　users＇　quality　of　experience　(QoE)　for　VR　360-degree　videos　mainly　focus　on　video　coding　and　transmission　schemes,　with　a　limited　investigation　into　the　impacts　of　wireless　channels.　To　fill　this　gap,　this　paper　emulates　VR　360-degree　video　transmission　on　three　kinds　of　wireless　channels:　additive　Gaussian　white　noise　(AWGN),　Rayleigh　fading,　and　Rician　fading　channels.　The　performance　metrics　for　the　wireless　physical　layer　including　signal-to-noise　ratio　(SNR),　end-to-end　delay,　and　bit　error　rate　are　investigated　for　their　impacts　on　the　performance　metrics　of　video　transmission,　including　video　bitrate,　stalling　time,　and　start-up　delay.　Finally,　a　comprehensive　QoE　score　is　derived　based　on　measured　application-layer　quality.　Furthermore,　we　fit　the　functions:　i)　a　log-scaling　law　of　QoE　vs.　bandwidth,　and　ii)　a　Sigmoid　function-scaling　law　for　QoE　vs.　SNR.　The　results　shed　light　on　guiding　physical　layer　network　optimization　aimed　at　improving　the　subjective　QoE　of　VR　videos.
